Randomized Controlled Trial Clinical Trial
[The effect of continuous intra-articular and intra-bursal infusion of lidocaine on postoperative pain following shoulder arthroscopic surgery].
We evaluated the effects of continuous intra-articular and intra-bursal infusion of lidocaine on postoperative pain following shoulder arthroscopic surgery. Forty-one ASA I-II patients scheduled for shoulder arthroscopic surgery, were allocated into following four groups. The patients, after intra-articular arthroscopic surgery, either received intra-articular lidocaine (Group I, n = 10) or did not (Group III, n = 10). ⋯ The VAS scores and the number of analgesic requests were significantly lower (P < 0.05) in Group I than Group III, and in Group II than Group IV throughout the postoperative observation period. No adverse effects were observed during this study. We conclude that continuous intra-articular and intra-bursal infusion of lidocaine provides effective postoperative pain relief for shoulder arthroscopic surgery.

Randomized Controlled Trial Multicenter Study Clinical Trial
[Evaluation of efficiency of ACD-CPR and STD-CPR; a multi-institutional study].
We compared the efficacy of ACD-CPR and STD-CPR based on 64 multi-institutional reports. No significant differences were observed in the rate of restoration of spontaneous circulation (ROSC) and in cardiopulmonary parameters during CPR using the two methods. ⋯ ETCO2 never exceeded 20 mmHg in the non-ROSC cases, but it was higher in the ROSC cases. ACD-CPR is a good choice when trained persons are present or when extra hands are available to continue the CPR.

Randomized Controlled Trial Clinical Trial
[Dose-response study of preincisional buprenorphine on emergence time and postoperative analgesic requirement in patients anesthetized with sevoflurane].
The effect of intravenous buprenorphine on emergence time from sevoflurane anesthesia and postoperative analgesic requirement was evaluated after otolaryngeal surgeries. Forty-five patients were randomly assigned to one of three treatment groups (n = 15 each): Control-group received saline as a control; 2 micrograms-group received buprenorphine 2 micrograms.kg-1; and 4 micrograms-group received buprenorphine 4 micrograms.kg-1, respectively. Study drug was administered intravenously at the induction of general anesthesia. ⋯ In the control-group, the 2 micrograms-group, and the 4 micrograms-group, 10, 1, and 3 patients, requested additional analgesics during the first 24 hours after surgery, respectively (control-group vs. 2 micrograms-group and 4 micrograms-group, P < 0.05). Nausea and vomiting occurred more frequently in the 2 micrograms-group and the 4 micrograms-group. We conclude that buprenorphine (2 or 4 micrograms.kg-1) reduced analgesic requirement during the first 24 hours after surgery without delaying emergence from sevoflurane anesthesia.
