Researchers at the Yale School of Medicine have shown that hypnosis can reduce preoperative anxiety for adults undergoing ambulatory surgery.

Participants in the study were split into two groups prior to their surgery. Within the preoperative holding area, one group of patients received empathic attention from a staff member who listened to the patient and offered support, and the other group of patients underwent a 45-minute hypnotic session with the suggestion of relaxation and well being by an anesthesiologist trained in hypnosis.

Prior to the hypnosis, anxiety levels of both groups of patients were similar. Following intervention, participants in the hypnosis group reported significantly lower levels of anxiety.

Calmer surgery patients are important because reports have shown pre-surgery anxiety to be linked to greater postoperative pain, increased need for painkillers, and longer recovery times, according to the researchers.

The length of time patients spend under anesthesia during outpatient facial plastic surgery procedures is not linked to their risk of injury or death, according to a study in the January issue of the Archives of Facial Plastic Surgery.

In a study of 1,200 patients who underwent facial plastic surgery between July 1995 and February 2005, study authors found that 1,032, or 86%, were under anesthesia for more than 240 minutes. Participants who were in the longer anesthesia group underwent multiple facial procedures, while patients in the shorter anesthesia group had only rhinoplasty.

Each participant was monitored the day after surgery. No deaths were reported in the study, and the rate of complications was similar for patients in both groups. The authors report that there were no complications that are typically attributed to longer anesthesia times, including intractable postoperative nausea, vomiting, and pain.

The authors conclude that regulatory bodies that are creating surgical guidelines should have a detailed understanding of the specific risks associated with different types of surgery in order to avoid generalization and nondata-driven regulation.
