Randomized Controlled Trial Comparative Study Clinical TrialOnset and offset of intrathecal morphine versus nalbuphine for postoperative pain relief after total hip replacement.
We designed this study to compare the postoperative analgesic effects of intrathecal morphine and nalbuphine, the endpoints being onset and offset of action. ⋯ We conclude that after total hip replacement, administration of intrathecal nalbuphine resulted in a significantly faster onset of pain relief and shorter duration of analgesia than intrathecal morphine.

Randomized Controlled Trial Clinical TrialRandomised, placebo-controlled study of the postoperative analgesic effects of ketoprofen after spinal fusion surgery.
The additive effect of non-steroidal anti-inflammatory drugs administered with propacetamol after major orthopaedic surgery has not been studied. Thus, we performed a prospective, placebo-controlled study to assess the analgesic effects of ketoprofen in patients undergoing spinal fusion surgery and receiving propacetamol. ⋯ Ketoprofen reduced morphine requirements and improved postoperative analgesia in patients undergoing major spinal surgery and receiving propacetamol.

Randomized Controlled Trial Clinical TrialEffects of intraperitoneal lidocaine combined with intravenous or intraperitoneal tenoxicam on pain relief and bowel recovery after laparoscopic cholecystectomy.
Previous work has demonstrated that intraperitoneal (i.p.) lidocaine may provide analgesia after laparoscopic cholecystectomy. The aim of this prospective, randomized, double-blind study was to compare pain relief, recovery variables, and side effects after i.p. instillation of lidocaine plus tenoxicam given either i.v. or i.p. after laparoscopic cholecystectomy. ⋯ Combination of intraperitoneal lidocaine and tenoxicam provided better analgesia on movement, and faster return of bowel function compared with i.p. lidocaine and i.v. tenoxicam during the 24 h period after surgery.

Clinical TrialLight-guided intubation via the intubating laryngeal mask using a prototype illuminated flexible catheter. Clinical experience in 400 patients.
The transillumination of the soft tissues of the neck using lighted stylets has been used as an aid for tracheal intubation. We evaluated the efficacy and safety of a prototype illuminated flexible catheter to facilitate light-guided intubation through the intubating laryngeal mask. ⋯ We conclude that the use of the illuminated flexible catheter facilitates the intubation through the intubating laryngeal mask. The suggested light-guided intubating method proved to be a simple, safe and effective technique.

Case ReportsUse of an EEG-bispectral closed-loop delivery system for administering propofol.
Closed-loop control of propofol delivery was instituted in three patients who received a propofol infusion as part of: (Case 1) general "balanced" anesthesia, (Case 2) total intravenous anesthesia, and (Case 3) monitored anesthesia care. The bispectral index was the input variable used in a proportioned, integral and differential controller to determine the infusion rate of propofol required to maintain a stable level of hypnosis (Cases 1 and 2) or sedation (Case 3). This feedback control system provided intraoperative hemodynamic stability and a prompt recovery from the sedative-hypnotic effects of propofol.
