Randomized Controlled Trial Comparative Study Clinical TrialPostoperative analgesia at home after ambulatory hand surgery: a controlled comparison of tramadol, metamizol, and paracetamol.
We compared in a prospective, randomized, double-blinded study the analgesic efficacy of three drugs in 120 ASA I and II patients scheduled to undergo ambulatory hand surgery with IV regional anesthesia. At discharge, oral analgesic tablets were prescribed as follows: tramadol 100 mg every 6 h, metamizol 1 g every 6 h, and paracetamol (acetaminophen) 1 g every 6 h. Rescue medication consisted of oral dextropropoxyphene 100 mg on demand. ⋯ Although tramadol was more effective, its use was associated with the highest frequency and intensity of adverse effects and the most patient dissatisfaction. Metamizol and acetaminophen provided good analgesia with a small incidence of side effects. For patients undergoing ambulatory hand surgery, postoperative pain can last longer than 2-3 days, and there is a need for both better education before the procedure and oral analgesic therapy at home.

Randomized Controlled Trial Clinical TrialTransient neurologic symptoms after spinal anesthesia with lidocaine in obstetric patients.
We investigated the relationship between intrathecal lidocaine and transient neurologic symptoms in the obstetric population because lidocaine spinal anesthetics are commonly used for various obstetric procedures, and little has been reported in this regard from within this population. In this study, 58 ASA physical status I patients presenting for postpartum bilateral tubal ligation under spinal anesthesia were randomized to receive either hyperbaric 5% lidocaine or 0.75% bupivacaine in a double-blinded manner. ⋯ The incidence of transient neurologic symptoms with lidocaine was 3% (95% confidence interval = 0.1%--17.8%) and that with bupivacaine was 7% (95% confidence interval = 0.9%--23.5%), (P = not significant). Symptoms consistent with this syndrome occurred within 24 h without any associated sensory or motor deficits or functional impairment, and resolved within 48 h without any intervention.

Randomized Controlled Trial Comparative Study Clinical TrialThe use of esmolol as an alternative to remifentanil during desflurane anesthesia for fast-track outpatient gynecologic laparoscopic surgery.
We compared esmolol and remifentanil infusions with respect to their effect on intraoperative hemodynamic stability and early recovery after outpatient laparoscopic surgery when administered as IV adjuvants during desflurane anesthesia. After premedication with midazolam 2 mg IV, anesthesia was induced with propofol 2 mg. kg(-1) IV in combination with either esmolol 1 mg. kg(-1) IV (n = 27) or remifentanil 1 microg. kg(-1) IV (n = 26) and succinylcholine 1 mg. kg(-1) IV according to a randomized, double-blinded protocol. Anesthesia was initially maintained with desflurane 2.5% (subsequently titrated to maintain an electroencephalogram-bispectral index value of 60) and nitrous oxide 65% in oxygen. ⋯ Both drugs were associated with frequent "postanesthesia care unit bypass" rates (78-81%), short times to "home readiness" (119-120 min), excellent patient satisfaction (81-85%), and rapid resumption of normal activities (2.6-3.2 d). Fast-tracked patients were ready for discharge home significantly earlier (112 +/- 46 vs 151 +/- 50 min). We concluded that esmolol infusion is an acceptable alternative to remifentanil infusion for maintaining hemodynamic stability during desflurane-based fast-track anesthesia for outpatient gynecologic laparoscopic surgery.
