Effect of Self-acupressure on Middle Ear Barotrauma Associated With Hyperbaric Oxygen Therapy
Sponsor: Chang Gung Memorial Hospital
Summary
Middle ear barotrauma (MEB) is the most common complication during hyperbaric oxygen therapy (HBOT). Though Valsalva and Toynbee maneuvers have been proposed to prevent MEB, still some patients discontinue HBOT due to severe otalgia, hemorrhage or perforation of tympanic membrane associated with HBOT. Currently, there is no optimal prophylactic management for MEB associated with HBOT. The aim of this protocol is to investigate the efficacy of self-acupressure therapy on MEB associated with HBOT.

Interventions
Self-acupressure therapy
The self-acupressure therapy is as follows: Patients are in sitting position, applied firm pressure (3-5 kg of pressure) with the fingertips in a circular motion at a speed of two circles per second for a duration of one min per acupoint. A 1-2-s rest is applied after each ten circles. The complete process lasts for about 5 min.
Combined Valsalva and Toynbee maneuvers
Valsalva maneuver: blowing against a closed mouth and nostrils, increasing the middle ear pressure. Toynbee maneuver: swallowing while the mouth and nostrils are closed, decreasing the middle ear pressure.
