Movement of the endotracheal tube during laparoscopic hernia repair.
Laparoscopic surgery is not without its problems, and one of the less known is cephalad displacement of the carina and relative movement of the endotracheal tube in the trachea. The aetiology of this is presumably a consequence of both pneumoperitoneum and the Trendelenburg position frequently adopted during laparoscopic surgery. ⋯ We conclude that the endotracheal tube does not routinely migrate towards the carina when laparoscopic hernia repair is performed under these conditions.

Effects of vecuronium and rocuronium in antagonistic laryngeal muscles and the anterior tibial muscle in the cat.
Adequate vocal cord paralysis and full recovery of laryngeal muscle function are important when muscle relaxants are used perioperatively. This study was designed to compare the effects of vecuronium and rocuronium at the vocal cord abductor and adductor muscles and the anterior tibial muscle in cats. ⋯ In cats, the time course of neuromuscular blockade after vecuronium and rocuronium differs in antagonistic laryngeal muscles. The protective laryngeal function of glottis closure recovers later than vocal cord abduction after both vecuronium and rocuronium.
