A study of the hypothermic effects of general anaesthesia during breast surgery and its amelioration by the use of a thermal drape to most of the body exclusive of the operating site. Two groups of patients are compared, using a constant anaesthetic technique, a single surgeon and the same operating conditions except for the omission or inclusion of thermal drapes. A review of the homeostatic mechanisms of temperature control and other methods of maintaining body temperature are included.

BACKGROUND: For Ascension Health's Healthcare That Is Safe strategy, Sacred Heart Hospital (SHH) and Columbia St. Mary's (CSM) served as alpha sites to develop strategies to eliminate perioperative adverse events (POAEs). The alpha sites set an interim goal of a 50% reduction of POAEs, then 100%, or elimination of POAEs by July 2008.

OBJECTIVE: This study sought to evaluate whether surgical clips affect tissue conductivity and thereby alter the induction of radiofrequency ablation lesions and to determine whether therapy is safe after previous placement of clips in the liver. MATERIALS AND METHODS: An ex vivo porcine hepatic model was used. Three clips were placed around a radiofrequency electrode at 10, 20, and 30 mm from the point of insertion. Clips were arranged in a plane either perpendicular or parallel to the electrode track.

The upper oesophageal sphincter can prevent regurgitation of oesophageal contents into the pharynx following gastrooesophageal reflux in the awake patient. Upper oesophageal sphincter pressure was recorded with a Dent sleeve after hypnosis with midazolam (n = 7) and also during the rapid intravenous induction of anaesthesia with thiopentone (n = 16) or ketamine (n = 7). Thiopentone decreased mean (SD) sphincter pressure from an awake value of 43 (19) to 9 (7) mmHg (p less than 0.001) and midazolam from 38 (25) to 7 (3) mmHg (p less than 0.02).

OBJECTIVE: To compare the hemodynamic stability and time to recovery of consciousness after long-duration (> 3 h) neurosurgery with 2 anesthetic protocols: total intravenous anesthesia with propofol as the single hypnotic agent and inhalational anesthesia with isoflurane. PATIENTS AND METHOD: We studied 58 middle-aged patients (range 40-50 years) scheduled for intracranial surgery. The patients, who all scored over 13 on the Glasgow coma scale before surgery, were randomly divided into two groups: 27 in group I received isoflurane and 31 in group II received propofol.

Between April 1994 and June 1997, 197 thyroidectomies and 21 cervical explorations for hyperparathyroidism were performed under hypnosedation (HYP) and compared to the operative data and postoperative courses of a closely-matched population (n = 121) of patients operated on under general anaesthesia (GA). Conversion from hypnosis to GA was needed in two cases (1%). All surgeons reported better operating conditions for cervicotomy using HYP.

Since 1992, we have used hypnosis routinely in more than 1400 procedures in plastic surgery. Our clinical success and experience with this technique led us to test wether hypnosis using active patient collaboration, could be used as an effective adjunct to conscious intravenous sedation ("hypnosedation", (HS)) for endocrine surgery, as an alternative to general anaesthesia. On a total of 1905 cervical endocrine surgical procedures performed between 1995 and 1998, 296 thyroidectomies and 33 cervical explorations for hyperparathyroidism were conducted under HS.

BACKGROUND: The effects of anesthetics on airway protective reflexes have not been extensively characterized in children. The aim of this study was to compare the laryngeal reflex responses in children anesthetized with either sevoflurane or propofol under two levels of hypnosis using the Bispectral Index score (BIS). The authors hypothesized that the incidence of apnea with laryngospasm evoked by laryngeal stimulation would not differ between sevoflurane and propofol when used in equipotent doses and that laryngeal responsiveness would be diminished with increased levels of hypnosis.

Intraoperative awareness has been reported to occur in 0.8-5.0% of paediatric patients undergoing anaesthesia and, therefore, seems to be more common than in adults (incidence 0.1-0.2%). In adult patients, the consequences of intraoperative awareness are well known and can be severe, in children, however, they have not yet been adequately studied.

BACKGROUND: Changes in heart rate variability (HRV) during anesthesia likely result from the interaction of hypnosis, surgical stimulation, analgesia and direct cardiovascular effects of drugs, but the interaction between these variables is unclear. This study was designed to characterize the impact of both surgical nociception and analgesia on HRV in propofol-anesthetized patients.
