A Low Cost Face Mask for Inhalation Anaesthesia in Rats

Abstract

Inhalation anaesthesia in small laboratory rodents has become very popular in Biomedical Research. A  common method to deliver volatile anesthetic agents is through a face mask. The main disadvantage of this  method is the exposure of personnel to anaesthetic agents. The authors describe a low-cost face mask, made  with materials commonly accessible in the operating room that can be connected to an anaesthetic machine  eliminating personnel exposure to hazardous levels of anaesthetic agents and allowing for effective adjustments  to the anaesthetic depth.
