Randomized Controlled Trial Comparative Study Clinical TrialTropisetron or droperidol in the prevention of postoperative nausea and vomiting. A comparative, randomised, double-blind study in women undergoing laparoscopic cholecystectomy.
Women undergoing laparoscopic cholecystectomy are susceptible to postoperative nausea and vomiting (PONV). This study was undertaken to evaluate the efficacy of tropisetron or droperidol for preventing PONV after laparoscopic cholecystectomy. ⋯ Tropisetron, when compared with droperidol, had no better efficacy on the prevention of postoperative nausea but resulted in a significantly lower incidence of vomiting after laparoscopic cholecystectomy.

Block of the brachial plexus branches by the humeral route. A prospective study in 503 ambulatory patients. Proposal of a nerve-blocking sequence.
Brachial plexus is usually approached by the supraclavicular or axillary route. A technique for selective blockade of the branches of the plexus at the humeral canal using electrolocation has recently been proposed. The aim of the present study was to assess the feasibility of this technique in the ambulatory patient and to determine the optimal sequence of nerve-blocking. ⋯ This study shows that the nerve block at the humeral canal is an efficient and safe technique. Considering the onset times of nerve blocks, the following sequence for blockade can be recommended: median, ulnar, radial, musculocutaneous, medial (brachial and antebrachial) cutaneous nerves. The selective blockade of the main nerves of the upper limb at the humeral canal can be recommended for surgery of the forearm and the hand in the ambulatory patient.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialEpidural ropivacaine 7.5 mg/ml for elective Caesarean section: a double-blind comparison of efficacy and tolerability with bupivacaine 5 mg/ml.
Ropivacaine is a new local anaesthetic drug known to be less cardiotoxic than bupivacaine. The aims of this comparative study with bupivacaine were to evaluate efficacy, safety and tolerability for the mother and the neonate when using ropivacaine 7.5 mg/ml for epidural anaesthesia for elective Caesarean section. ⋯ Ropivacaine 7.5 mg/ml administered epidurally resulted in equally effective anaesthesia for Caesarean section as bupivacaine 5 mg/ml. Because of the lower cardiotoxicity of ropivacaine, the new amide has a potential in replacing bupivacaine when used epidurally for Caesarean section.

Meta AnalysisProphylactic ondansetron for postoperative emesis. Meta-analysis of its effectiveness in patients with previous history of postoperative nausea and vomiting.
The objective of this study was to compare, by means of meta-analysis, the postoperative antiemetic efficacy of ondansetron in patients with and without antecedents of postoperative nausea and vomiting. ⋯ The effectiveness of ondansetron in the prevention of postoperative vomiting is not affected by the patients' PH-PONV.

Case ReportsClinical experience using intrathecal (IT) bupivacaine infusion in three patients with complex regional pain syndrome type I (CRPS-I).
To date, there is no reliable method for treating the severe pain and for modifying the natural evolution of CRPS-I. Therefore, we explored the effect of long-term IT bupivacaine infusion (with or without buprenorphine) on this syndrome. ⋯ The IT pain treatment with bupivacaine (with or without buprenorphine) alleviated the "refractory" pain, but affected neither the associated symptoms and signs of the CRPS-I, nor its natural evolution. Thus, the IT treatment cannot be recommended in preference to other pain treatment regimens for CRPS-I.
