[Truncal anesthesia of the foot at the level of the ankle: an additional reference mark for the approach to the posterior tibial nerve].
Nerve trunk blocks at the ankle could be a most interesting technique of regional anaesthesia. Unfortunately the posterior tibial nerve is difficult to locate with the usual recommended anatomical landmarks (the tibialis posterior artery). The use of the flexor hallucis longus tendon as an additional landmark has been tested in 71 patients scheduled for surgery on the foot (emergency trauma surgery, amputations, ingrowing toe-nails, removal of bedsores, verrucas). ⋯ Anaesthesia was obtained in 10 +/- 3 min, lasting from 180 to 240 min. There were 88.7% excellent results (n = 63), with 7% fair (n = 5) and 4.2% bad (n = 3) results. Failure concerned 5 cases of tibial nerve block, often due to landmark difficulties (great toe previously amputated, significant ankle oedema, lack of operator experience) and, in 3 cases, forgetting to block a nerve involved.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
Continuous blockade of the lumbar plexus after knee surgery--postoperative analgesia and bupivacaine plasma concentrations. A controlled clinical trial.
In a double blind, randomised, controlled investigation the analgesic effect of a continuous block of the lumbar plexus with bupivacaine compared with sodium chloride was examined in 20 patients with postoperative pain after knee-joint surgery. The infusion was given through a catheter inserted in the neurovascular fascial sheath of the femoral nerve, according to the three-in-one block technique. The patients treated with bupivacaine had significantly lower pain scores and a significantly lower demand for morphine. Side effects related to the catheters or the infusions of bupivacaine were not observed.

Randomized Controlled Trial Clinical Trial
Ilioinguinal nerve blockade for analgesia after caesarean section.
Bilateral ilioinguinal nerve blockade was performed, using 0.5% plain bupivacaine 10 ml to each side, in 13 patients having elective Caesarean section under general anaesthesia. Pain scores and requirement for postoperative analgesia were compared with 13 patients in a control group. ⋯ In the control group, patients required more analgesia in the first 24 h after surgery compared with patients having ilioinguinal nerve blockade. There were no observed adverse effects following nerve blocks.

Randomized Controlled Trial Clinical Trial
Rectus sheath block for diagnostic laparoscopy.
Sixty adult females of ASA grade 1 or 2 scheduled to undergo diagnostic laparoscopy were allocated randomly to one of two groups. In group A, laparoscopy was performed with a standardised general anaesthetic technique alone. ⋯ Postoperative analgesia was assessed at 1, 6 and 10 hours after operation. Visual analogue pain scores in group B were significantly lower than in group A despite a greater use of intramuscular analgesic injections in group A (p less than 0.005 in each case).
