Randomized Controlled TrialAnalgesic efficacy of the intra-articular administration of high doses of morphine in patients undergoing total knee arthroplasty.
Although the efficacy of intraarticular (IA) morphine is still controversial, it has been shown that higher doses promote better results and consequently decrease postoperative analgesic consumption, characterizing a dose-dependent peripheral action. A controlled, randomized, double-blind study was undertaken to evaluate the efficacy of the intra-articular administration of 10 mg of morphine in patients undergoing total knee arthroplasty. ⋯ The treatment group had lower NS than the control group in M1 and M2, while significant differences were not observed in the other moments. The time until the first request of analgesics was significantly higher in the treatment group, and analgesic consumption in the first 24 hours was also lower in this group. The incidence of side effects did not differ between both groups. We concluded that the postoperative IA administration of 10 mg of morphine promoted a longer period without rescue analgesics and reduced their consumption in the first 24 hours.

Randomized Controlled Trial Comparative StudyDisposable versus reusable laryngeal tube suction for ventilation in patients undergoing laparoscopic cholecystectomy.
The laryngeal tube suction II (LTS-II) is a recent version of reusable supraglottic airway devices allowing gastric drainage. In this prospective, randomized study we compared insertion and ventilation of disposable LTS-II (LTS-D) with reusable type (LTS-II) for airway management under conditions with elevated intra abdominal pressure induced by capnoperitoneum. ⋯ Both devices provide a secure airway under conditions of elevated intra abdominal pressure.
