Randomized Controlled Trial Clinical Trial
Efficacy of therapeutic suggestions for improved postoperative recovery presented during general anesthesia.
There have been claims that the postoperative course of patients may be improved by presentation during general anesthesia of therapeutic suggestions which predict a rapid and comfortable postoperative recovery. This study evaluated the effectiveness of such therapeutic suggestions under double-blind and randomized conditions. A tape recording predicting a smooth recovery during a short postoperative stay without pain, nausea, or vomiting was played during anesthesia to about half the patients (N = 109), while the remaining, control patients were played a blank tape instead (N = 100). ⋯ There were no meaningful, significant differences in postoperative recovery of patients receiving therapeutic suggestions and controls. These negative results were not likely to be due to insensitivity of the assessments of recovery, as they showed meaningful interrelations among themselves and numerous differences in recovery following different types of surgery. Widespread utilization of therapeutic suggestions as a routine operating room procedure seems premature in the absence of adequate replication of previously published positive studies.

Application of the laryngeal mask airway to thyroid surgery and the preservation of the recurrent laryngeal nerve.
We report our experience of using the laryngeal mask airway (LMA) in 13 consecutive patients undergoing thyroid surgery and discuss the advantages and limitations of the technique. We also describe a method, based on the use of the LMA, for identifying and preserving the recurrent laryngeal nerve during thyroid surgery.
