Randomized Controlled Trial Comparative Study Clinical Trial[Analgesia after laparoscopic cholecystectomy by intraperitoneal administration of bupivacaine].
The aims of this study were to assess the analgesic effect of the intraperitoneal topical administration of 0.375% bupivacaine in patients undergoing laparoscopic cholecystectomy and to carry out a pharmacokinetic study of bupivacaine administered topically by intraperitoneal route. ⋯ Intraperitoneal administration of 0.6 mL.kg-1 of 0.375% bupivacaine is ineffective in reducing postoperative pain after laparoscopic cholecystectomy. Furthermore these high doses of bupivacaine may result in toxic plasma concentrations. This technique is not safe and cannot be recommended.

Review[Indications and role of albumin for vascular loading during postoperative intensive care].
Prospective clinical trials comparing human albumin to other plasma volume expanders during the three first postoperative days in adult patients were analysed. Fifteen studies were selected. Nine of them concerned the evaluation during the immediate postoperative period, after cardiac surgery with cardiopulmonary bypass (CPB). ⋯ After cardiac surgery, mainly uncomplicated coronary artery bypass graft or valve replacement, albumin can be substituted by HES. These conclusions are only valid for blood losses below 50% of blood volume. The place of isooncotic albumin for fluid resuscitation in case of blood loss exceeding 50% of blood volume cannot be specified.

Randomized Controlled Trial Comparative Study Clinical Trial[Intubation conditions: importance of the rate of repetition of the train-of-four].
To assess that neuromuscular relaxation onset of the adductor pollicis (AP) is related to neuromuscular stimulation rate. To assess that train-of-four (TOF) at 0.05 Hz is a more accurate indicator of optimal tracheal intubation time and conditions, than TOF at 0.08 Hz. ⋯ Low stimulation rate (TOF at 0.05 Hz) of AP is a reliable technique to determine the appropriate intubation time for patients paralyzed with vecuronium.

Review[Indications and role of albumin for vascular loading in trauma patients and during preoperative period].
The use of albumin solutions for volume replacement remains controversial. The last American guidelines recommend the use of albumin for resuscitation in case of a contra-indication of artificial colloids or the requirement of sodium restriction. Recent trials did not show any beneficial effect of albumin on the mortality and morbidity rates. ⋯ For resuscitation, albumin could be used when the recommended upper limit of hydroxyethyl starch vol-ume has been reached and fresh frozen plasma not yet required. During preoperative haemodilution, low molecular weight hydroxyethyl starch has at least the same efficacy as albumin. When a rheological effect is required, albumin could be used.

Review[Three-in-one block or femoral nerve block. What should be done and how?].
The "3 in 1" block and the femoral nerve block are widely used for lower limb surgery and postoperative analgesia. Whether these blocks are in fact a same regional block with two different names or represent definitively two different blocks remains controversial. A large number of anatomical as well as functional variations of the lumbar plexus have been described and complicate a rational analysis of the spread of local anaesthetics following these blocks. ⋯ However, once the "3 in 1" block is well performed, a complete anaesthesia covering the territories of the femoral nerve, the lateral femoral cutaneous nerve, and the obturator nerve occurs. Specific indications of each technique are different: major knee surgery and postoperative analgesia for the "3-in-1" block and leg surgery for femoral nerve block. The best approach for knee arthroscopy remains open for discussion.
