Oxygen therapy breathes new life into woman lying in coma

हाइपर माने सामान्य से ऊपर (ज्यादा )और बारिक बोले तो वायुदाब (प्रेशर )से सम्बंधित वायुमंडलीय दाब को मिलीबार में अभिव्यक्त किया जाता है। 

हाइपरबारिक मेडिसिन का मतलब हुआ बढे हुए ऑक्सीजन दाब (दाबित ऑक्सीजन )द्वारा चिकित्सा। जिसमें मरीज़ को एक ऐसे कक्ष में रखा जा सकता है जिसमें उसे ऑक्सीजन सामान्य वायु दाब से दो या तीन गुना दाब पर मुहैया करवाई जाती है। ऐसा होने पर बढ़े  हुए दाब पर शरीर के हर ऊतक  को ऑक्सीजन पहुँचती है जो चंद ग्रोथ फेक्टर्स के निर्माण को प्रेरित करती है जादुई स्टेम सेल्स का निर्माण भी करवा सकती  है ऐसे में मधुमेह जैसे रोगों में लाइलाज हो चुके आसानी से न भरे जा सकने वाले जख्मों को भी भरने के मौके पैदा हो जाते हैं ,एम्पुटेशन को टाला जा सकता है। किसी धमनी में किसी भी वजह से एयर एम्बोलस (एयर बबिल)फंस जाने पर दाबित ऑक्सीजन उसे हटाने में सहायक सिद्ध हुई है अन्यान्य रोगों का समाधान बनती है बढ़े  हुए दाब पर दी गई ऑक्सीजन चिकित्सा। पढ़िए एक विरल अनूठा समाधान ऑक्सीजन चिकत्सा पर : 

Oxygen therapy breathes new life into woman lying in 

coma 

Mumbai: When Sonabai Morasker boards a bus for Shippur village near Kolhapur on April 

25,she will leave without the 

memory of four days she spent in a state of unconsciousnessor comain a city hospital.A widow 

who manages her tiny 

farm back home,Morasker did not wake up after the effects of the anaesthesia wore off 

following an open heart surgery 

to replace a leaky mitral valve in February first week.



An MRI scan showed the culpritair bubbles,or air embolism,in her brain.With Morasker 

showing 

no signs of 

improvement even after four days,doctors at L H Hiranandani Hospital in Powai placed her in 

an oxygen chamber.And 

in 

what could pass off for the script of a Bollywood blockbuster,within 15 minutes of receiving 

oxygen therapy,the 42-year-

old woman opened her eyes and wanted to know where she was.


When TOI met Morasker in her rented room in Kharghar last week,she had no recollection of 

the drama that unfolded 

on 

February 2.I remember the operation theatres bright lights before closing my eyes.The next 

thing was I opened my eyes 

in a similar room, she said.





Sonabai has no memory of four days after her heart surgery 



Its rare that air bubbles dont damage brain,say doctors 

Sonabai Morasker,who has survived an air bubble in her brain,has no recollection of the four 

days after her heart 

surgery in February.


Immediately after she came around,the doctor asked her if she recognized me.She said,This 

is 

my Prakash, her son-in-

law Prakash Kesarkar revealed.


Hiranandani Hospital doctors are amazed at Moraskers complete recovery.Her neurological 

examination after a month 

of discharge showed that she hasnt suffered any brain damage, said Dr Vaishnav 

Manmath,who specializes in 

hyperbaric oxygen therapy.It is rare that air bubbles detected in a persons do not cause any 

damage.


Morasker suffers from rheumatic heart disease,a condition in which the heart gets damaged 

due to a bacterial infection 

in childhood.She couldnt walk even a few steps without getting breathless.The sarpanch gave 

us a letter and 

recommended that we come to Hiranandani Hospital for free treatment, said 

Prakash.Accordingly,Morasker underwent 

a valve replacement at the Powai hospital on February 2.The next morning,the ICU nurses 

informed her family that she 

hadnt woken up after the surgery.We were shattered as we waited for doctors to go through a 

series of tests and 

treatment, Prakash said.According to doctors,air bubbles can occur due to a number of 

reasonsfrom being strapped to 

a heart-lung machine to fixing of an intravenous line.Cardiologist Dr Ameya Amonkar 


said,There is no way of pinning 

down a reason for air bubbles.As hyperbaric oxygen is the best treatment it,we immediately 

recommended her for it. 

According to Dr Manmath,as oxygen was being delivered under pressure,the air bubbles in 

Moraskers brain got 

dissolved into the blood plasma.



The medical world,however,is a bit skeptical.If the woman has no brain damage even after 

bubbles stopped blood flow 

to her brain for four days,it means that she is plain lucky, said a doctor from Nair Hospital who 

didnt want to be 

identified.


Dr Sangeeta Rawat,who heads the neurological department of KEM Hospital in Parel,said,It 

seems like a mystery.How 

was it that there was no brain damage despite there being no blood supply for so long She felt 

the coma was perhaps 

induced by some metabolic reason such as lack of some electrolytes rather than air 

bubbles.Sonabai is blissfully 

unaware of all the medical nuances.Shes happy that she can now walk fast and climb stairs 

without having to stop.

MIND MATTERS 

Coma is a prolonged state of unconsciousness in which a person is unresponsive to his or her 

environment.The 

patient looks like he / she is sleeping,but fails to wake up.It can be temporary or permanent 

depending on the injury to 

the brain On February 2,Sonabai Morasker (43) is admitted to a Powai hospital for a mitral 

heart valve replacement 

surgery She doesnt gain consciousness after the anaesthesia effect wears off Doctors then 

run 


a series of 

tests,including an MRI,and find that an air bubble (air embolism) in her brain is the cause of her 

unconsciousness She 


is given oxygen therapy Hyperbaric medicine (known as hyperbaric oxygen therapy [HBOT]) is 

the medical use of oxygen 

at a level higher than atmospheric pressure When a patient is placed in HBOT,it enhances the 

bodys natural healing 

process by inhalation of 100% oxygen in a total body chamber 

Case Of The Racing Legend 


In December 2013,former Formula 1 driver Michael Schumacher suffers severe brain injuries 

after striking a rock while 

skiing.The German racer has been in a medically induced coma at Grenoble University 

Hospital where he is being 

treated since January 

Hyperbaric oxygen therapy


Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized room. Hyperbaric 

oxygen therapy is a well-established treatment for decompression sickness, a hazard of scuba 

diving. Other conditions treated with hyperbaric oxygen therapy include serious infections, 

bubbles of air in your blood vessels, and wounds that won't heal as a result of diabetes or 

radiation injury.

In a hyperbaric oxygen therapy room, the air pressure is raised up to three times higher than 

normal air pressure. Under these conditions, your lungs can gather up to three times more 

oxygen than would be possible breathing pure oxygen at normal air pressure.

Your blood carries this oxygen throughout your body, stimulating the release of substances 
called growth factors and stem cells, which promote healing.

Why it's done


Your body's tissues need an adequate supply of oxygen to function. When tissue is injured, it 
requires even more oxygen to survive. Hyperbaric oxygen therapy increases the amount of 
oxygen your blood can carry. An increase in blood oxygen temporarily restores normal levels of 
blood gases and tissue function to promote healing and fight infection.
Hyperbaric oxygen therapy is used to treat a wide assortment of medical conditions, and 
different medical institutions use this treatment in a variety of ways. Your doctor may suggest 
hyperbaric oxygen therapy if you have one of the following conditions:
  • Bubbles of air in your blood vessels (arterial gas embolism)
  • Decompression sickness
  • Carbon monoxide poisoning
  • A wound that won't heal
  • A crushing injury
  • Gangrene
  • Skin or bone infection that causes tissue death
  • Radiation injuries
  • Burns
  • Skin grafts or skin flaps at risk of tissue death
  • Severe anemia

Although more research regarding hyperbaric oxygen therapy is under way, currently there's 

insufficient scientific evidence to support claims that hyperbaric oxygen therapy can effectively 

treat the following conditions:
  • Allergies
  • Arthritis
  • Autism
  • Cancer
  • Cerebral palsy
  • Chronic fatigue syndrome
  • Cirrhosis
  • Fibromyalgia
  • Gastrointestinal ulcers
  • Stroke

Risks


Hyperbaric oxygen therapy is generally a safe procedure, and complications are rare. But, as with any medical procedure, it does carry some risk.
Potential complications include:
  • Temporary nearsightedness (myopia) caused by increased blood oxygen levels
  • Middle ear and inner ear injuries, including leaking fluid and eardrum rupture, due to increased air pressure
  • Organ damage caused by air pressure changes (barotrauma)
  • Seizures as a result of too much oxygen (oxygen toxicity) in your central nervous system

How you prepare


Pure oxygen can cause fire if there is a source of ignition, such as a spark or flame, and 

adequate fuel. Because of this, you can't take any items into the hyperbaric oxygen therapy 

room that could ignite a fire, such as lighters or battery powered devices. In addition, to limit 

sources of excess fuel, you may need to remove hair and wound-care products that are 

petroleum-based and potentially flammable. Ask a member of your health care team for 

specific instructions prior to your first hyperbaric oxygen therapy session.

What you can expect


During hyperbaric oxygen therapy

Hyperbaric oxygen therapy typically is performed as an outpatient procedure and does not 
require hospitalization. If you're already hospitalized and require hyperbaric oxygen therapy, 
you'll remain in the hospital during a hyperbaric oxygen therapy session. Alternately, you may 
be transported to and from the hospital to a hyperbaric oxygen therapy session if the 
procedure 
is performed at an outside facility.
Depending on the type of medical institution you go to and the reason you require treatment, 
you may receive hyperbaric oxygen therapy in one of two settings:
  • A unit designed for one person. In an individual (monoplace) unit, you lie down on a padded table that slides into a clear plastic tube about 7 feet long.
During hyperbaric oxygen therapy, the air pressure in the room is approximately two to three 
times normal air pressure. The increased air pressure will create a temporary feeling of 
fullness 
in your ears — similar to what you might feel in an airplane or at a high elevation — that can be 
relieved by yawning.
A therapy session may last from one to two hours. Members of your health care team monitor 
you and the therapy unit throughout your treatment.

After hyperbaric oxygen therapy

You may feel lightheaded following your treatment. Typically, this feeling goes away within a 
few 
minutes and doesn't limit normal activities.
  • A room designed to accommodate several people. In a multiperson hyperbaric oxygen 
  • room — which usually looks like a hospital waiting room inside — you may sit or lie down. A 
  • lightweight, clear hood may be placed over your head to deliver the oxygen to you, or you 
  • may wear a mask over your face to receive the oxygen.

Results


To be effective, hyperbaric oxygen therapy requires more than one session. The number of 

hyperbaric oxygen therapy sessions you require depends on your medical condition. Some 
conditions, such as carbon monoxide poisoning, can be treated in as few as three visits. 
Others, such as nonhealing wounds, may require 25 to 30 treatments.
Hyperbaric oxygen therapy alone can often effectively treat decompression sickness, arterial 
gas embolism and severe carbon monoxide poisoning.
To effectively treat other conditions, hyperbaric oxygen therapy is used as part of a 
comprehensive treatment plan and administered in conjunction with additional therapies and 
medications that fit your individual needs.
