Hyperbaric Oxygen
Therapy for Cerebral Palsy
Page 8 of 10
What are the
benefits of HBOT
-
Improved quality of life. By promoting
healing of the problem wound, adding HBO therapy can mean the difference
between disability, loss of limb, and healing.
-
Improved care. By delivering high
oxygen under pressure, hypoxic tissue can be restored and healing takes
place.
-
Lower costs. By accelerating healing
and the reduction of extensive medical care, HBOT coincides with
cost-containment goals of major insurance providers.
What are the
contraindications of HBO?
-
Upper respiratory infections and
chronic sinusitis make it difficult for the patient to clear his/her ears.
Often decongestants are used to open the sinuses, and occasionally surgical
myringotomy is necessary to maintain open Eustachian tubes. Sometimes it is
better to interrupt treatment for three or four days to allow the
respiratory infection to clear.
-
High fever can predispose to oxygen
seizures but in such cases drugs can be given to lower the fever.
-
In some patients with severe emphysema
and COPD the only stimulus to breathe is hypoxemia, as they have lost their
sensitivity to normal levels of CO-2. These patients may cease breathing if
placed in the hyperbaric chamber.
-
Patients who have a lower than normal
seizure threshold may be more prone to develop seizures due to oxygen
toxicity. If HBO treatment is a requirement, additional anticonvulsants can
be added to these patients' regimens.
-
HBO treatment is absolutely
contraindicated for patients with pneumothorax, or collapse lung, and
caution is used with HBO treatment if a patient has a history of spontaneous
pneumothorax.
-
HBO is not recommended for patients
who have active cancerous conditions.
-
If a woman is pregnant, HBO is not
recommended for precautionary reasons, except in life-threatening
emergencies.
What are the
possible side effects of HBOT?
-
Barotrauma or ear and sinus
discomfort. A patient may experience a fullness and an uncomfortable
pressure in the ears. This can be relieved by slowing the rate of
descent/ascent so that the patient is comfortable with the change in
pressure. Also, decongestants taken prior to treatment is sometimes helpful.
-
Oxygen toxicity. This may occur,
particularly when therapy is given at more than 2.4 ATA. This is minimized
by not exposing the patient to greater pressure or longer times than are
known to be safe for the body and its organs. Some patients are susceptible
to high O2 partial pressures. Treatment is the discontinuance of HBOT.
-
Serous otitis. Rarely, fluid
accumulates in the ears as a result of changes in pressure in the ears and
sinuses resulting in a possible ruptured membrane. Treatment is the
discontinuance of HBOT and a referral to an ENT physician.
-
Temporary worsening of
near-sightedness (Myopia). After twenty or more treatments, especially if
the patient is over forty years of age, it is possible to experience a
temporary diminution in the ability to focus on thins far away. This is
temporary and vision typically returns to its pre-treatment level about six
weeks after cessation of therapy. It is not advisable to get a new
prescription for glasses until at least eight weeks have passed after
hyperbaric therapy.
-
Temporary improvement in
far-sightedness (Presbyopia). Also, after twenty or more treatments,
especially if the patent is over forty years of age, there is a possibility
to experience an improvement in the ability to see things close up or to
read without glasses. However, this is temporary and the vision should
return to its previous level of acuity in about six weeks following
cessation of Hyperbaric treatment.
-
Numb fingers. A small portion of
patients sometimes notice a numb feeling in the fourth and fifth fingers of
the hands after twenty or more treatments. This should not be of concern and
should disappear within about six weeks following cessation of therapy.
What is the treatment process like?
The treatment process may be modified for
different types of chambers, either the monoplace or the multi-place chamber. In
the monoplace chamber, one person at a time is treated, whereas in the
multiplace chamber where more than one patient is treated at the same time, with
an attendant present in the chamber.
Only 100% cotton gown, which is supplied, is permitted in the chamber. No
cosmetics, perfumes, deodorants, hair preparations, wigs or jewelry are worn
during the treatments. Patients are advised not to take carbonated drinks or
alcohol for at least four hours prior to each treatment, and that they should
give up smoking and tobacco products, as these interfere with the body's ability
to transport oxygen.
Once inside the chamber, the patient will be experience the changing pressure
which is the same as that felt in an airplane when ascending or landing. Prior
to the treatment, the patient is instructed in techniques of equalizing the
ear/sinus pressure by yawning, swallowing, or attempting to blow through the
nose while holding it shut. During the treatment the individual will be
breathing 100% oxygen, dispersing oxygen into the blood plasma and delivering up
to 15 times as much oxygen to tissues as would breathing room air. The treatment
length is 60 - 90 minutes, depending the diagnosis and the physician's
determination of treatment. The acrylic walls allow for the trained technicians
to closely monitor the patient, as well as providing comfortable viewing out of
the chamber. From inside the chamber the patient can always communicate with the
attending technician via intercom, as well as watch TV, listen to music, or just
take a nap.
What does the Hyperbaric
technician need to know before giving HBOT?
-
you experience a cold, flu symptoms,
sinus or nasal congestion, or chest congestion
-
there may be a possibility of
pregnancy
-
your medications have changed
-
you have skipped a meal prior to HBO
treatment
-
you are a diabetic and did not take
your insulin prior to treatment
-
you have any concerns or anxiety
