Intermittent Positive Pressure Inflation During Microscopic Endolaryngeal Surgery

Explosion during surgery for gastric outlet obstruction

“…During ITJV, intratracheal pressure should always be monitored [2]. Less reliable is to listen carefully to the change of the noise emitting from the glottis during respiration [I].…”

“…Less reliable is to listen carefully to the change of the noise emitting from the glottis during respiration [I]. If only intratracheal pressure is monitored [2], or if HFJV is used, an automatic cut-off of the jet at a safe pressure should be incorporated into the ventilator [3], because the time from total closure of the glottis to dangerously high pressure is too short for the anaesthetist to react. If monitoring of airway pressure is impossible, 'a safe overdose of muscle relaxant' should be used [4].…”

Complications and technical aspects of jet ventilation for endolaryngeal procedures

“…Airway pressure monitoring helps to avoid the risk of barotrauma in connection with translaryngeal catheter jet ventilation ( 18). With adequate monitoring of ITJV ( 19), we have avoided barotrauma during 25 years (150–200 cases/year).…”
