Title: [abstract] THE EARS IN DIVING, OTOLOGIC AND PULMONARY BAROTRAUMA
Author: Warriner, RA
Abstract: INTRODUCTION: Boyle's Law Problems: Barotrauma: pneumocephalus, sinus, middle ear, inner ear, teeth, pneumothorax, subcutaneous emphysema, pneumomediastinum - pneumopercardium, hollow viscus perforation and gas embolism. METHOD:1. Identification of types of lung over pressure injuries (LOPI) and predisposing factors, extravascular air/gas in LOPI, subcutaneous emphysema, mediastinal emphysema, pneumopericardium, pneumothorax and tension pneumothorax. 2. Ear and Sinus Barotrauma: ear components: middle ear, inner ear, tympanic membrane anatomy and physiology, evaluating ear equilization- typanometry as aid to assessing Eustacian tube patiency, and patency of nasal passages. Equalizing techniques, equalizing problems. Indications, site and technique for myringotomy. External ear- Otitis Externa and Barotitis Externa: Cause, prevention and treatment. 3. Sinus Barotrauma, Dental Barotrauma, Mask squeeze RESULT: Guidelines to prevent ear and sinus barotraumas: Confirm equalizing and let patient practice, let the patient blow his/her nose pre HBO, insert nasal decongestant for the initial treatment, prompt equalizing 1:4 seconds during pressurization, monitor patient closely during pressurization, plan to have Otovent/Polizer (or Heliox) available, ensure patients DO NOT equalize on ascent, examine the ears after the first treatment and treat any MEBT, instruct patients to continue equalizing for 2 hours post treatment, if unsuccessful/complicated: myringotomy/PETs. CONCLUSION: 1. Prevention of MEBT (Middle ear barotraumas): Explain, Educate, Evaluate, Exercise, Encourage, Enhance, and Elective Myringotomy/PETs, 2. What to do if a patient experiences ear pain during a dive: Discontinue compression, Decompress 0.5 meters, Differentiate cause, Direct proper techniques, and Decompress to surface, and 3. Treatment of MEBT. Diagnose degree, Determine cause, Decongest, Delay diving until healed.
