Anesthetized surgical patients frequently become hypothermic, because of decreased metabolic heat production, increased heat loss, surgical exposure, and dry respiration gases. Intraoperative hypothermia may trigger postoperative protein breakdown, shivering, myocardial ischemia, and many other problems. For that reason, heat conservation is a major anesthetic management. ⋯ Rectal temperature increased 0.62 degrees C after 60 minutes in the Warm Touch group, but significant changes were absent in warming blanket group. Temperature gradient between the rectum and finger-tip skin decreased markedly in the Warm Touch group. This study suggests that Warm Touch is useful to restore body temperature and to prevent postoperative problems arising from intraoperative hypothermia.

Comparative Study Clinical Trial Controlled Clinical Trial
[Postoperative nausea and vomiting after gynecologic abdominal surgery--a comparison of propofol versus inhalational technique].
Propofol has been reported to reduce emesis. This study was performed to evaluate the incidence of postoperative nausea and vomiting (PONV) in gynecologic abdominal surgery patients after propofol anesthesia and inhalational anesthesia. Sixty patients were evaluated for the incidence of PONV. ⋯ Those of postoperative vomiting were 0.17 after propofol and 1.00 following inhalational anesthesia (P < 0.01). For the gynecologic abdominal surgery patients, PONV was significantly less following intravenous anesthesia with propofol than after isoflurane or sevoflurane inhalational anesthesia. This study indicated that propofol anesthesia was useful in reducing PONV after gynecologic abdominal surgery.

Comparative Study
[Which laryngoscope is the most stressful in laryngoscopy; Macintosh, Miller, or McCoy?].
Stress responses during laryngoscopy were compared among the situations using three different laryngoscopes, Macintosh (curved standard blade), Miller (straight blade), or McCoy (levering). Blood pressure, heart rate (in 58 patients) and plasma concentration of catecholamines (in 29 patients) were measured before, during and after laryngoscopy without tracheal intubation. ⋯ Heart rate and plasma norepinephrine concentration were not different among the three groups. These results suggest that the stress response during laryngoscopy without intubation is the biggest in using the Miller laryngoscope and the smallest in using the McCoy laryngoscope.
