Abstract

Introduction: One significant side effect of hyperbaric oxygen treatment (HBOT) is middle ear barotrauma (MEBT) may require tympanostomy tube (grommet) insertion by the Ear, Nose and Throat service. Where timely HBOT is needed, routine insertion of grommets under local anaesthesia (LA) is becoming common.

Aims: To investigate the differences between patients receiving HBOT and concurrent grommets under LA versus general anesthesia (GA) at The Townsville Hospital (TTH).

Methods: A retrospective chart analysis of patients receiving HBOT between 2008 and 2012 and requiring grommets was undertaken.

Results: Thirty-one (5%) out of 685 patients treated with HBOT from 2008 to 2012 received grommets. Twelve cases received grommets under LA, and 19 under GA. Twenty out of the 31 cases had grommets following MEBT and the remainder prophylactically. Complications of grommet insertion comprised two cases with blocked grommets. There was a significant difference (P = 0.005) in the time in days from ENT referral to HBOT between the LA group (median 1 day, range 0-13 days) and the GA group (median 8 days, range 0-98 days).

Conclusion: A greater number of hyperbaric patients received grommets under GA than LA at the TTH. Insertion of grommets under LA was safe, offering advantages to both the patient and the treating team in the setting of HBOT-associated otic barotrauma.
