Nitrous oxide use and endotracheal tube rupture.
Nitrous oxide is an important and widely used anesthetic agent. However, during lengthy surgical procedures, significant amounts of nitrous oxide diffuse into the endotracheal tube cuff, causing sequelae that may include increased cuff pressures, tracheal trauma, increased postoperative discomfort, and cuff rupture. In this paper, two cases are presented in which the endotracheal tube cuff used to deliver this anesthetic agent ruptured after more than four hours of surgery. Two simple means of limiting the diffusion of nitrous oxide into the cuff and thus preventing this occurrence are described.
