Sudden Appearance of Water in Flowmeter During Air/Oxygen and Sevoflurane Anaesthesia

摘要

Endotracheal intubation was performed, and a water bubbling sound was heard from the anaesthesia device immediately after the release of gases to administer the O2-air-sevoflurane mixture. The flowmeter on the anaesthesia device was then found to be filled with water. The breakdown of the dryer in the medical air compressor system was determined as the source of the problem, since a greasy fluid mixture was released from the air-wall outlets in all rooms. Consequently, the anaesthesia team should keep in mind that problems as seen in the current case might emerge and should be alert.
