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.

Randomized Controlled Trial Clinical Trial[Prevention of increase of blood pressure and intracranial pressure during endotracheal intubation in neurosurgery: esmolol versus lidocaine].
To compare the preventive effects of esmolol and lidocaine on the increase in mean arterial pressure (MAP) and intracranial pressure (ICP) during endotracheal intubation in neurosurgery. ⋯ Esmolol or lidocaine as an iv bolus of 1.5 mg.kg-1 before laryngoscopy and intubation do not completely prevent the increase in MAP and ICP.

Review[Is albumin administration useful in critical care for burnt patients?].
The most typical reaction of the organism after a major burn consists in transcapillary shift from plasma into interstitial space. Capillary hyperpermeability, but also changes in colloid osmotic gradient and decrease in interstitial hydrostatic pressure, explain the fluid shift to burned and, at minor importance, non burned areas during the first post-burn day. The extent of capillary hyperpermeability results in inefficiency of colloid infusions in reducing fluid shift to burned areas. ⋯ However, for most groups, restoration of a functional interstitial space has priority during the 24 first post-burn hours, justifying crystalloid supply without colloids. Furthermore, colloid infusion could be responsible for delayed pulmonary oedema, in the first days following initial fluid replacement. After 24 post-burn hours, in patients experiencing severe albumin depletion, infusion of human albumin is justified, in order to favour oedema resorption.

Multicenter Study[Anesthesia and intensive care of subarachnoid hemorrhage. A survey on practice in 32 centres].
To assess the current practices in anaesthesia and intensive care in patients experiencing subarachnoid haemorrhage (SAH). ⋯ Twenty-nine French and three non French centers answered the questionnaire. In 14 centers, more than 60 SAH had been treated in the previous year. Angiography was performed under sedation with a benzodiazepine associated with an opioid (54%). Criteria for choosing an endovascular approach were the site of the aneurysm (81%), its neck size (42%) and the underlying disease (42%). Anaesthesia was induced with either propofol (60%) or thiopentone (40%) associated with an opioid and a muscle relaxant. It was maintained with either isoflurane (59%) or propofol (41%). Nitrous oxide was often associated (62%). During anaesthesia, nimodipine (84%), mannitol (69%), anticonvulsants (47%), dopamine (31%) and lidocaine (9%) were also administered. Postoperatively, nimodipine was administered for prophylaxis of vasospasm (97%) and transcranial Doppler was employed to diagnose vasospasm (50%). Other techniques of care included hypervolaemia (89%), controlled arterial hypertension (36%) and haemodilution (36%).

Comparative Study Clinical Trial[Combined spinal and epidural analgesia for labor. Prolongation by addition of a minidose of clonidine to sufentanil. An initial study].
The effect of adding a minidose of clonidine to intrathecal sufentanil during the early first stage of a painful labour was evaluated in this preliminary open-label, non-randomised trial. Group 1 received sufentanil 5 micrograms + clonidine 30 micrograms intrathecally (n = 10) and group 2 only intrathecal sufentanil 5 micrograms (n = 11). The two groups were not statistically different regard-ing age, weight, height, primiparity (67 vs 50%), oxytocin use (37 vs 60%), initial cervical dilation (m +/- DS: 2.9 +/- 1.1 vs 2.9 +/- 1 cm) and VAS pain scores (70 +/- 14 vs 68 +/- 19 mm). ⋯ Side effects, such as hypotension, pruritus and sedation, were not statistically different between groups. Nausea and motor blockade did not occur. In conclusion, the addition of a minidose (30 micrograms) of clonidine to sufentanil 5 micrograms given intrathecally seems to potentiate markedly the analgesia obtained during the early first stage of labour.
