Randomized Controlled Trial Clinical Trial
Post-operative effects of tramadol administered at wound closure.
The aim of this prospective, randomized and double-blind study was to assess the effects of a high dose of the analgesic tramadol administered at the conclusion of surgery on extubation time, sedation, and post-anaesthetic shivering. Forty adult patients, ASA physical status I or II, underwent laparoscopic surgery of about 1 h duration and received a standardized anaesthesia that was maintained with isoflurane in O2/N2O. Tramadol 3 mg kg-1 (n = 20) was administered intravenously at the beginning of wound closure, and was compared with saline (n = 20). ⋯ There were no adverse effects on time to extubation and sedation, and discharge-ready time was shorter in the tramadol group (P < 0.05 compared with control). Pain scores in the post-anaesthesia care unit (PACU) were statistically not different between the two groups, but significantly more supplemental medication was administered in the control group to treat shivering and/or pain. In conclusion, administration of a high dose of tramadol at the end of surgery prevents post-anaesthetic shivering without prolongation of extubation time, and shortens the PACU/discharge-ready time.

Randomized Controlled Trial Clinical Trial
Reducing the incidence of sore throat with the laryngeal mask airway.
The incidence of sore throat after the use of the laryngeal mask was assessed with a randomized trial in 839 patients. Sore throat occurred more often in women, older patients or after multiple insertion attempts. It was found that the frequency in women, but not in men, was lowered from 11.9% to 3.9% (P = 0.012) by reducing intracuff pressure to the minimum required for an effective seal.
