Most of us are hoping that, through some kind of nuclear accident or other, we’ll get super powers. It’s just a matter of time, right? If you could pick what power would you take? Super strength is the superpower that everybody wants most. So the first thing you’ll want to do in your career as a superhero is try to lift something huge and heavy. Well, I have good news for you some of these dreams can be realized by the exoskeleton – a device that can increase a person’s muscular strength due to an external frame.
Like many other things in our lives, exoskeletons gradually step over the boundary that separates the ambitious dreams from our everyday life. Being originally just ideas, concepts, myths and legends of science fiction, today new versions of exoskeletons appear almost every week.
Let’s have a quick look at exoskeleton’s history. The earliest exoskeleton-like device was invented by Russian engineer Nicholas Yagn. According to U.S. Patents 420 179(A) Nicholas Yagn In his patent application wrote “Be it known that I, NICHOLAS YAGN, a subject of the Russian Emperor, residing at St. Petersburg, Russia, have invented certain new and useful Improvements in Apparatus for Facilitating Walking, Running, and Jumping”. That Apparatus was patented half a year later in January 28, 1890.
But according to defense technical information center the first TRUE exoskeleton was co-developed by General Electric and United States military in the 1960’s and it was named Hardiman. It made lifting 25 pounds feel like lifting only 1 pound. Wow, it sounds great, but unfortunately it was impractical due to its 1500 pound weight. A lot of experiments and researches were made to make a better light-weight exoskeleton. Nowadays a robotic suit that was once real in a comic book, now gives superhuman power to the wearer and is available for use in military field, medical field and physical working field.
Let me share with you how this technology can be a real benefit to the military. Imagine that you are a soldier and you have to operate high in the Afghanistan Mountains. You also were ordered to take 220 pounds up in that level. Now think how exhausted you would be once you got there. But exoskeleton provides you with the ability to carry that weight same distance but to have energy left to execute the mission. The good example of that exoskeleton is TALOS (Tactical Assault Light Operator Suit). According to the article “Welcome to TALOS, Where Tony Stark Meets G.I. Joe.” by Daniel Nadler, The TALOS is armored exoskeleton, which not only protects the soldier from being hit by bullets and fragments, but also allows him to easily and freely move around the battlefield with equipment weighing up to 100 pounds. It also has the ability to monitor vitals and stop bleeding in case of receiving the wound and includes “a wearable computer, similar to Google Glass, to help soldiers aim their weapons”.
While some organizations are working on developing exoskeletons for military purposes, to create the perfect soldier for killing enemies, others are working on developing suits that allow the paraplegic and injured people to lead the fulfilling life. Thus the HAL exoskeleton designed specifically for the rehabilitation of people with problems of the musculoskeletal system. Anneli Nilsson in her article ” Gait Training Early After Stroke with a New Exoskeleton” says that exoskeleton obeys bio-electrical signals emanating from the human brain as the muscles in the human body. This exoskeleton allows such people to return to normal active life. And those who only recently could not get up from their wheelchairs, are now able to at least walk again and even climb stairs. Hybrid Assistive Limb exoskeleton also designed for the elderly, for whom even a trip to the grocery store has become a complex and sometimes impossible process.
The most significant example of exoskeleton is the exoskeleton that is available for use in physical working field. According to Neil Bowdler, the journalist of BBC News, “Engineers in Italy have developed a wearable robot which can enable users to lift up to 110 pounds in each extended hand. It could be developed to work in factories or to clear debris and rescue survivors in earthquake zones”. Another suit that still doesn’t have name was developed in Japan to post-accident clean-up at Fukushima. According to the article “Powered Exoskeleton to Help Cleanup Fukushima Post Meltdown” this suit increases the force that protects against radioactive dust and saves from overheating. The most interesting thing in that Suit – is that it really looks like the suit of the Iron Man.
To sum up, we have seen that exoskeleton can increase the person’s strength and allow him to lift heavy-weight things. It can be used in military, medical and physical working fields. Nowadays technologies that seemed unimaginable to us amaze us and allow us to do the things we could previously only dream of. Next time when you will be watching movies such as Iron Man, Star Wars, Matrix, G.I. Joe: The Rise of Cobra, Spy Kids: All the Time in the World and Aliens remember that robotic suits are no longer science fiction. The unbelievable future for exoskeletons have already come. And remember that the next Iron man is YOU!

Sacks (1999) describes encephalitis lethargica as a sleeping-sickness disease that killed five million people during the epidemic from 1916 to 1926 all over the world. It appeared mysteriously from nowhere. Some researches consider it as the aftermath of the Spanish flue. This disease attacks brain and nerve cells, but it necessary to understand that patients are not brain dead. They are still very intelligent and smart people. They are just imprisoned in themselves for decades. Different patients have different symptoms. For example, sleepiness, personality changes, tics and stiffness as well as totally lacking of emotions, feelings and desires. Post-encephalitic syndrome appears years later after the attack of encephalitic letargica. Patients can have the same symptoms as in encephalitic lethargica or can have different ones. Some of the symptoms are stiffness, sweaty, tics, respiratory crisis, festinatia and many others. Symptoms can remit and disappear, stay for years or lead to the rapid death. This illness has no one pattern, but, in fact, it is very unpredictable. Every patient can tell his or her own experience and all these stories won’t be the same.
Moreover, patients’ stories and experiences are the part of themselves. In other words these are what formed their self-identity. However, in Sacks encephalitic lethargica, post-encephalitic syndrome and the L-DOPA treatment made his patients feel as if they were losing their “sense of ‘self'” (p.54). By this term, Sacks means self-define – who they are and who they were, feelings and emotions, and whether or not the internal person matches the external one.
First of all, a person is always asking him or herself “who am I?”. Sacks’s patients also asked themselves who they were and who they became. Frances D. was very successful in her life. She had a career as a legal secretary and was very active woman in social and civil affairs until the illness attacked her (p.40). She used to have a fully control over her life, but becoming ill, she described her life as “[…] I cannot start and I cannot stop. Either I am held still, or I am forces to accelerate. I no longer seem to have any in-between states” (as citied in Sacks, p.40). Frances was not already the same as she was before the disease. She was out of control of her life. Hester Y. also wrote in her diary “I’m fifty-five, bent double…a cripple… a hag… I used to be pretty, Dr. Sacks; you’d never believe it now… I’ve lost my husband and son […] I’ve been asleep for twenty years and grown old in my sleep” (as citied in Sacks, p.104-105). This terrible disease had stolen their identity, their sense of “self”. They both understood that they were not the same as they were in the best time of their lives, in the time when they were beautiful and successful. This disease also had stolen the families that were also a part of who they were. But some patients had no even chances to develop their identity as it happened with Rolando P. who was struck with encephalitic lethargica at the age of 30 months old. “I’ve been shut up in illness since the day I was born… That’s a hell of a life for someone to have… Why the hell couldn’t I have died as a kid?” (as citied in Sacks, p.125). Patients with stolen sense of “self” wanted to end their lives with suicide or just die by themselves of despair and hopelessness.
Second, the sense of “self” is about feelings and emotions, because they also form people’s identity. Some patients were emotionless even when someone tried to be intolerable to them. This disastrous disease thieved all of emotions from Magda. She had only feelings by apathy and indifference. Nothing concerned her. It seemed that she was incapable of emotional reaction:
I ceased to have any moods, I ceased to care about anything. Nothing moved me – not even the death of my parents. I forgot what it felt like to be happy or unhappy. Was it good or bad? It was neither. It was nothing (as citied in Sacks, p. 71).
Other people, being peaceful and emotionally equable before the disease, became very restless and irritable after that. For example, Mr. O faced with frequent mood-swings. He could either fall into depression or exultant mood (p. 88).
After taking L-DOPA, patients first felt very delighted and inspired. They could finally express their emotions through laugh and tears decades later. Leonardo described his first L-DOPA experience as “I feel like a man in love. I have broken thorough the barriers which cut me off from love” (as citied in Sacks, p. 209). It seemed that L-DOPA was like a solving of all the problems; it was the drug that was able to return the patients back to the real life, to the sense of “self”, to the emotions that they hadn’t have for years. The evidence for that is the speech of Hester:
I’m a new person, I feel it, I feel it inside, I’m a brand new person. I feel so much, I can’t tell you what I feel. Everything’s changed, it’s going to be a new life now… […] I would like to express my feelings fully. It is so long since I had any feelings. I can’t find the words for my feelings. I would like to have a dictionary to find words for my feelings… (as cited in Sacks, p. 101-102).
But, unfortunately, this inspirational period didn’t last long in most cases. After exultant mood, patients lost their feelings of peace and calm. L-DOPA exploded their emotions in a bad way. Frances depicted her emotional state as:
That’s it! You’ve thrown-out the whole pharmacy at me. I’ve been up, down, sideways, inside-out, and everything else. I’ve been pushed, pulled, squeezed, and twisted. I’ve gone faster, and slower, as well as so fast I actually stayed in one place. And I keep opening up and closing down, like a human concertina…” (as citied in Sacks, p. 61).
As a result some patients asked the doctor to stop the course of L-DOPA, because they felt that it was better for them to stay alone, imprisoned in themselves (as citied in Sacks, p. 219).
In opposition to Frances, Mrs. Y. adapted herself to these reactions to L-DOPA. She successfully piloted herself “through physiological storms of an incredible ferocity and unpredictability” (p. 107).
The most significant component of sense of “self” is whether or not the internal person matches the external one. After awakening patients found out that they became 20-40 years older compared to what they remembered about themselves. Rose R. said, “I know it’s ’69, I know I’m 64 – but I feel it’s ’26, I feel I’m 21” (as citied in Sacks, p. 83). All patients reacted differently on the fact that they are much older than they were before. Some accepted this fact quite easily, some didn’t. “But she is a Sleeping Beauty whose ‘awakening’ was unbearable to her, and who will never be awoken again” (p.87). As it was mentioned above, Hester’s internal person didn’t match the external one too. She remembered herself beautiful and pretty, but she understood that she was not the same anymore at her 55 (as citied in Sacks, p.104-105).
To sum up all above, all patients in spite of the fact that their brain and nerve cells were affected by the disease were very intelligent. Some were good in reading, some were good in writing, crocheting, doing crosswords and in many other things. Undoubtedly, this illness stole the part of their sense of “self” in three different aspects of it: in self-defining, in feelings and emotions, and in matching the internal person to the external one. But still they were the personalities with the strong characters.

Neurocognitive disorder is a disease of a mental health due to which nerve cells – neurons – are damaged; as a result they are not able to function normally and die. People with this disease have troubles in everyday activities, because of decline in memory, behavior, bodily functions and other basic skills. Dementia, as a category of the neurocognitive disorder, maybe caused by depression, side effects from medications, delirium, using of alcohol, etc. According to Gaugler, James, Johnson, Scholz, and Weuve (2014) there are different types of dementia, such as Alzheimer’s disease, Parkinson’s disease, vascular dementia, Creutzfeldt -Jakob disease, dementia with Lewy bodies, Frontotemporal lobar degeneration, mixed dementia, pressure hydrocephalus, and others (p. 6-7).
Alzheimer’s disease is the most common type of dementia. It was first identified more than 100 years ago. According to statistic, about 5.2 million Americans of different ages have this disease in 2014 (p.16). In addition, “almost two-thirds of Americans with Alzheimer’s are women”(p. 17). Alzheimer’s symptoms are “difficulty remembering recent conversations, names or events […]; apathy and depression […] impaired communication, disorientation, confusion, poor judgment, behavior changes and, ultimately, difficulty speaking, swallowing and walking” (p.6). However, “the brain changes of Alzheimer’s may begin 20 or more years before symptoms appear”. There are some risk factors. The first factor is age. People of 65 or older are susceptible to this disease. The second factor is family history. Individuals, who have parents or siblings with that disease, are at risk (p.9). Cardiovascular disease can be the other risk factor. “A healthy heart helps ensure that enough blood is pumped through these blood vessels, and healthy blood vessels help ensure that the brain is supplied with the oxygen and nutrient-rich blood it needs to function normally” (p.10). Scientist also discovered the link between education and the disease. “People with fewer years of formal education are at higher risk for Alzheimer’s and other dementias than those with more years of formal education” (p.11).
Parkinson’s disease is another type of dementia. It’s “a chronic and progressive movement disorder meaning that symptoms continue and worsen over time” (“What is Parkinson’s Disease?”, n.d.). There are about one million people with Parkinson’s disease in the US. Zotz, T. G. G., Souza, E. A., Israel, V. L., and Loureiro, A. P. C. (2013) reported that:
With the clinical diagnosis of Parkinson’s disease, the individual may show an alteration in postural reactions such as straightening, balance, protective extension, difficulty in corporal rotation and reduced muscular strength. Such symptoms are accentuated when the patient is subjected to situations of stress, fatigue or pressure, which can exacerbate the freezing phenomenon and postural compromise, leading to a sudden loss of balance (p. 102).
According to Gaugler, James, Johnson, Scholz, and Weuve scientists reported two kinds of treatment for neurocognitive diseases: pharmacologic and non-pharmacologic. Pharmacologic treatment is based on drugs, which effectiveness may vary from patient to patient.”Non-pharmacologic therapies are those that employ approaches other than medication, such as physical therapy and reminiscence therapy (therapy in which photos and other familiar items may be used to elicit recall)” (p.14).
Physical activity plays a huge role in neurorehabilitation process. According to Bowes, Dawson, Jepson, and McCabe (2013) it positively affects “the cognition, activities of daily life and independence, functional ability, and mental health” (p.2). If physical activity is undertaken in a group then patients increase their social network, as a result, they don’t feel loneliness. It is also very important to choose the right type of physical activity:
For example, walking outdoors may help re-establish a connection with nature and the local community; dancing may provide enjoyment and feelings of wellbeing. Physical activity is also likely to have physical health benefits, helping maintain a normal lifestyle and reducing the risk of other disease (e.g. heart disease) (p.2).
Physical activity increases patients’ strength, improves their sleep quality, their balance becomes better too, and there are also significant reduction in falls and a reduction in wandering behavior. For example, “She’s developed a lot more strength and she now can get herself to the toilet and back. So that in itself is great. (Interview 9103)”. (p.7-8). Gardening, games and housework could also help patients to maintain or return skills:
I think it’s about maintaining skills as well, particularly with things like the gardening, which some of the men really enjoy. And they have a good workout sometimes… And it’s normality… and keeping the skills that they’ve got. (Interview 8682) (p.8).
Based on the researches made in Bowes, Dawson, Jepson, and McCabe it becomes clear that physical activity benefits patients and improve their overall quality of lives. One of the best physical activities for patients with neurocognitive diseases is the aquatic therapy.
Water has a number of unique physical properties that are appropriate for various rehabilitation purposes. These properties include a relatively high specific thermal capacity and thermal conductivity, as well as the ability to provide resistance and the hydrostatical pressure on the body and its buoyancy. The two forces – the gravity and buoyancy act simultaneously on the human body in the water. Moreover, in the aquatic environment patients could perform movements in three dimensions, which are impossible in the air; it is a great social and psychological significance for people with disabilities. The buoyancy of the human body in the water is used in healing and rehabilitation practice for reducing stress, compression on joints, muscles, and connective tissue, as well as strain on the heart that is caused by the excessive body weight. The physical characteristics of the water allow patients to do a wide range of exercises more easily than it is possible on land. An important role for the recovery and rehabilitation does the hydrostatic water pressure. It increases proportionally to the depth of immersion of man. Immersion in water can be a supplement to circulation or peripheral edema due to venous or lymphatic insufficiency. Zotz, T. G. G., Souza, E. A., Israel, V. L., and Loureiro, A. P. C. reported that aquatic therapy can “improve the quality of life, reduce postural instability and the risk of falling in the elderly, and to enhance treatments for different disorders” (p.102).That is why hydrotherapy or aquatic therapy has positive effects on patients with neurologic and musculoskeletal conditions.
According to Myers, Capek, Shill, and Sabbagh (2013), “patients with decreased conditioning, cognitive impairments, reduced strength and endurance, head and spinal cord injuries, stroke, amputation, arthritis, osteoporosis, chronic back pain, and movement disorders may benefit from aquatic therapy”. There are also groups of patients for whom the aquatic therapy is contradicted. Such patients are persons with aquaphobia, fever, infections, cardiovascular disease, open wounds and incontinence. Patients with incontinence can be the “candidates for this therapy only if they are toileted before entering the pool and are provided with commercially available incontinence swim briefs” (p.4).
It is well known that the water influence positively on human’s body. Here emerges the question as to what effects the aquatic therapy has on patients with neurocognitive diseases? Because of the wide range of healing properties of water, the aquatic therapy benefits patients and can be an important part of the neurological rehabilitation.
First of all, it has the effect on the musculoskeletal system. Zotz, T. G. G., Souza, E. A., Israel, V. L., and Loureiro, A. P. C. mentioned that aquatic therapy “may be an excellent alternative to land exercise for individuals who lack confidence, have a high risk of falling, or have joint pain that limits their ability to practice center-of-gravity shifts beyond the limits of their base of support” (p.104). Myers, Capek, Shill, and Sabbagh also reported that “Buoyancy in the water and the viscosity of water compared with air enable nonambulatory persons and those at high risk of falls to practice balancing skills while strengthening their lower extremity musculature without the risk of falling”. Patients with neurocognitive diseases and problems with movements can move freely in the water without fear of falling. As a result, water exercisers improve their postural and motor skills. “This study implies that while gait, balance, and lower body strengthening activities reduce fall risk, aquatic exercises are more effective” (p. 5). Therapist should also be careful with some patients who have increased adipose tissue or hypotonicity, because such patients may become unstable. Moreover, according to Morris (1995) “decreased weightbearing through the joints may further diminish sensory input for clients with sensory deficits”. But if the appropriate water depth is used, these problems can be avoided (p. 22). In addition, when a patient immerses in the water to a level of the neck, hydrostatic pressure of the water increases his blood flow in the non-working muscles. This kind of increasing in the muscle blood flow improves the muscular performance by oxygen saturation and removal of metabolic products. Thus, muscle training becomes more effective.
Aquatic therapy exercises, their duration and frequency should be also prescribed individually for every patient. In that way, patient of 89-year-old with Alzheimer’s disease, in Myers, Capek, Shill, and Sabbagh, was prescribed aquatic therapy “twice weekly for 30 minutes over a period of 3 months”. As a result, his fall risk scores trended downward (p.3).
The second example of the aquatic therapy’s effects is the cardiovascular effect. In many ways, this effect is caused by the influence of hydrostatic pressure. It causes a change in the functional state of the cardiovascular system, even in a motionless person who stands in the water. According to Hall, Swinkels, Briddon, and McCabe (2008) these “mechanisms are based around the effects of hydrostatic pressure, which by virtue of its effect on the cardiovascular system may relieve pain by reducing peripheral edema and, centrally, by dampening sympathetic nervous activity” (p.873). When a patient is immersed in the water in an upright position of the body, the hydrostatic pressure on the lower limbs contributes the transferring of the venous blood from the periphery to the heart, but this effect will only occur if the patient is in the water up to the neck. In that position central venous pressure increases to about 60%, and the heart volume and the stroke volume to about 30% (p.877).
The respiratory effect is the third advantage of the aquatic therapy. Ide, Belini, and Caromano (2005) told that “the aquatic respiratory exercise strengthened aspiratory muscles. We believe that this improvement occurred because of the influence of the physical properties of water which increase the volunteers’ respiratory efforts compared to exercising in air” (p.155). Moreover, water immersion of the body results transferring of blood from the periphery, increasing blood flow in the organs of the thoracic cavity, and the increment of hydrostatic pressure on the chest increases the resistance of its chest excursions, thereby reducing the vital capacity and enhancing the muscle work of apparatus of external respiration. Reduced weight bearing due to buoyancy and increased support of abdominals which is provided by the hydrostatic pressure of water, can help patients with a weak breathing diaphragm. Consequently, the load that falling on respiratory system during exercises in water can be used to improve the respiratory function and strength of respiratory muscles. According to Becker (2009) “A review in 2006 concluded that respiratory muscle training tended to improve expiratory muscle strength, vital capacity, and residual volume” (p.863).
There are different breathing results depending on the temperature of the water. Еhe breath-holding occurred at the first minutes of the cold hydroprocedure, than the breathing becomes more frequent and, finally, deepens and slows down. Warm water therapy treatments don’t not significantly change the quality of breathing, but speaking about hot water therapy, it speeds up and reduces the depth of breathing.
The most significant example of positive effects of the aquatic rehabilitation is psychophysiological effect. According to Broach and Dattilo (1996), “psychological benefits of participants in aquatic therapy have been identified to include improved mood, enhanced self-esteem and body image, and decreased anxiety and depression” (p.212). Water immersion forms a powerful sensory inflow from skin receptors of different modalities that can radically change the functional state of the central nervous system and vegetative nervous system, significantly increase the energy potential of the brain and its plasticity, enabling the higher nervous activity. Hot water, increasing the sensitivity of the mechanical and thermal receptors of the skin, and making more frequent the number of afferent impulses, has a stimulating effect. Cold hydro procedures (the first phase of the reaction) leads to the similar effect. Prolonged use of procedures with both cold and hot water follows by the development of the second phase of the reaction – the depression of central nervous system (p.215).
Psychological effects are also dependent on water temperature. Immersion in warm water causes a general relaxation and comfort. On the contrary, cold water gives a flow of energy for most people. The neutral effect of the warm water can be used to create a feeling of comfort and reassurance of overexcited or aggressive patients, whereas the activating effect of cold water is used to increase the activity during exercises for those who usually have little activity.
It is believed that the observed psychological effects including mood improvement may be caused by the activation process in the reticular formation. When a patient takes a hot bath, the concentration of endorphins in his blood plasma increases and as a result can cause his or her euphoric reaction. For example, in Myers, Capek, Shill, and Sabbagh, the stuff noticed that their 89-year-old patient “was smiling more and talking more clearly without his usual trouble finding words. He even joked with the staff” (p.4).
To sum up, it is known from ancient times that water has healing properties and influences positively on human’s body. Thus, the aquatic therapy is used in neurological rehabilitation of patients with neurocognitive diseases. The aquatic therapy benefits patients on musculoskeletal and cardiovascular systems. Patients also have the respiratory and psychophysiological effects after the aquatic therapy. Aquatic therapy is one of the most effective methods of recovery and rehabilitation, only in the case when it is taken into account the functional condition of a patient and met the security measures for its implementation.

Gawande (2007) shows the relations between doctors and patients as well as the medicine behind the scene; it is like a separate world that is unseen to a regular person. In this world the doctor does his best to make the patient feel better, to prescribe a better medication, to become a good doctor and even better. This word “better” is going through the book from the beginning up to the end. Gawande identifies three topics: “Diligence”, “Doing Right”, and “Ingenuity”. He tells the readers about the importance of simple health care procedures like washing hands in order to drop in the epidemic rate in the hospitals, about the doctors who worked on mopping-up the polio among the Indian population, and about those who strived to save the lives of American soldiers in Iraq. Comfort level for the patients and cultural requirements are also discussed as well as insurance systems and service pricelists. The most significant problems that are mentioned by Gawande are the suing the doctors for their malpractices, and whether or not doctors should participate in executions by lethal injection. At the end the readers can learn more about how become a good doctor, how accept the failures, reflect on failures and find new solutions – even through creativity – to avoid these failures in the future.
Gawande hit upon a very important idea that “But making medicine go right is less often like making a difficult diagnosis than like making sure everyone washes their hands” (p.21). By this statement Gawande means that often people think that medicine is only about diagnosis, but in fact the health of an every single person is consists of thousands of steps, such as following health care rules, fighting till the end, and being creative.
First of all, following health care rules can prevent serious illnesses and diseases. According to Gawande, “Bacterial counts on the hands range from five thousand to five million colony-forming units per square centimeter. […]. The worst place is under the fingernails” (p.17). Doctors examine a lot of patients each day and if they don’t wash their hands, don’t use sterile gloves and don’t sterilize the instruments, they can easily communicate infection from one patient to another. Gawande acknowledges his possible mistakes in this passage:
Until that moment, when I stood there looking at the sign on his door, it had not occurred to me that I might have given him that infection. But the truth is I may have. One of us certainly did (p. 28).
Due to doctors either are lazy to follow hand hygiene rules or just forget about them, millions of patients are infected in the hospitals and as a result many of them die. Such doctors and nurses can be easily sued for malpractice. However, they all should understand that this simple step of washing hands can save a lot of lives and drop in the epidemic rate in the hospitals. Thus, lives of millions of patients are literally in the doctors’ hands.
Another instance of following the health care rules to avoid serious diseases is to be vaccinated when you should to be. When the epidemic breaks out, scientists do their best to find the vaccine for this or that disease. Gawande gives us an example of polio – the disease that strikes children under age five in India (p. 35). A huge campaign for polio immunization was launched there. Thousands of vaccinators went from house to house to inoculate children. It was up to parents whether or not do this vaccination to their children. But they had to understand that this simple process of immunization could save the life of their children and stop the spreading of the disease. Unfortunately, not all people realized that and as a result a lot of children became paralyzed because of not taking the drop. Gawande describes the conversation between mother and the doctor:
The mother said that a health worker had come around with polio drops a few weeks before her daughter became sick. But she had heard from other villagers that children were getting fevers from the drops. So she refused the vaccination. A look of profound sadness now swept over her (p. 50).
In that way, it is very important to follow health care rules, because these are what help people to stay healthy, prevent diseases and avoid terrible results, such as death.
Still another example of thousands of small steps that make the path to the success is fight till the end. Due to the progress in medicine, there are big chances for soldiers to survive after getting injuries during the war such as gunshot wounds to the stomach, liver, chest and others. One of the main important things is whether or not doctors start the treatment on time and whether or not they fight till the end to save the soldiers’ lives. In the war every minute and even every second has its own value. That’s why time is one of the cruelest things during the war. Colonel Ronald Bellamy claimed, “Civilian surgeons talk of having a “Golden Hour” during which most trauma victims can be saved”. But there are also “Golden Five Minutes” for soldiers with blood loss (as citied in Gawande, p. 57). If during these minutes the urgent treatment has started, probably, the soldiers would live. Moreover, it is also important what kind of treatment is provided and whether or not doctors put their whole soul, all their desires to save the soldiers. Life is priceless, that’s why doctors have to do their best to pull soldiers out of the death.
People also ask doctors very often questions like “Should they put her through yet more of this? Or should they take her home and let her die?” But where is the border between what doctors can do and what they can’t do (p. 159)? According to Gawande, “the truth is we want doctors who fight” (p. 159). “Even when we don’t know that a patient can be completely normal and healthy, we want doctors to fight” (p. 160). Such a great responsibility lies with doctors. They should definitely fight. Only this kind of behavior can lead the doctors to the success, even if they were not able to save someone’s life. We never know what the last attempt can do. Maybe the last desperate attempt can lead the patient to the recovery. That’s why it is so important to fight till the very end, especially when the patients, their friends and relatives believe in doctors’ help so much.
The most significant example of how thousands of small steps make the path to the success is doctors’ ingenuity. Ingenuity is not less important than doctors’ skills and professionalism. Only due to all these things together, these simple steps, doctors can be successful in what they do. “Nonetheless, what I saw was: better is possible. It does not take genius. It takes diligence. It takes moral clarity. It takes ingenuity. And above all, it takes a willingness to try” (p. 246). Doctors don’t have to be afraid of being creative and should give a try to something they have invented, even if it seems so simple and primitive. Who knows maybe exactly this innovation will improve the quality of the medicine and will help to save people’s lives. Gawande gives us an example of this kind of simple idea. It is a measurement of a newborn’s physical condition that was invented by Virginia Apgar – the first woman who was admitted to the surgical residency at Columbia University College of Physicians and Surgeons (p.185). “The Apgar Score, as it became universally known, allowed nurses to rate the condition of babies at birth on a scale from zero to ten” (p. 187). This innovation amazed doctors. It allowed them to give an immediate feedback to what they did. According to Gawande “The score also changed the choices they made about how to do better” (p. 190).
To sum up all above, Gawande considers that the ultimate success consists not only of difficult diagnosis, but it is the result of cooperation between doctors and patients. Moreover thousands of steps are essential to the way to the success. Following health care tips, fighting up to the end and doctors’ ingenuity these are what can save millions of lives and lead to the doctors’ professional triumph. However, not only in the medical field these steps are very important. Our whole life should be based on single steps that will lead us to the height of our success.
