A Family Doctor’s Tale – BAROTRAUMA
What is Barotrauma?
Barotrauma can occur in workers exposed to compressed air environment.
Barotrauma can affect air filled spaces in the body for example the sinuses, ears and lungs.
What is the cause of Barotrauma?
The most common cause is diving and tunneling works.
What are the Signs and symptoms of Barotrauma?
Barotrauma presents with symptoms of:
1.Joint pains
2.rashes
3.breathing symptoms
4.neurological symptoms
5.intravascular coagulation in severe cases
What are the types of Barotrauma?
Barotrauma is divided into :
1.Sinus barotrauma with acute pain over the sinus area or nasal or postnasal bleeding
2.Middle ear Barotrauma with pain in the ear, bleeding from the ear, burst eardrum,together with hypoacusis, tinnitus, vertigo and hearing loss
3.Inner ear Barotrauma with severe vertigo and hearing loss of affected side
4.Pulmonary Barotrauma with chest pain, breathlessness, unconsciousness, subcutaneous emphysema.
What are the risk factors for Barotrauma?
Risk factors for barotrauma are:
1.medical unfitness – workers with pre=existing medical conditions,chronic disease of the ears, poor air passages of the lungs are at higher risk
2.any sudden changes of pressures -pressures of more than 1 bar cause higher risk of barotrauma
3.long working hours in compressed air( more than 4 hours)
4.failure to follow proper decompression procedure
5.smoking
6.coughing
7.breath holding
8.infections involving the ear or upper respiratory tract
Diagnostic Criteria of Work relatedness:
A good occupational history to determine the worker’s exposure to hyperbaric or high pressure environment.
The worker may be exposed to:
1.tunneling or shaft sinking in water bearing strata
2.caisson works on river beds
3.pressure checks on aircraft
4.work in medical locks or recompression chambers
5.diving
Investigation to establish work relationship to barotrauma:
Correlate exposure history and work periods to symptoms of compression and investigation results such as sinus, chest, long bones x-rays, audiograms.
Check correlation with workers’ record of work in compressed air or diving.
What is the management of Barotrauma?
Management:
1.Treatment for barotrauma may involve the use of antihistamines, decongestants, analgesics and antibiotics depending on how severe the case is.
2.Sinus x-rays, audiograms and tympanograms are useful to further investigate the condition.
How is Barotrauma prevented?
Prevention:
1.Avoid further exposure to compressed air during recovering from barotrauma.
2.Avoid entering compressed air environment if there is a cold, sore throat, earache or chest infection.
3.treat cases of contact dermatitis with creams and corticosteroids.
