Randomized Controlled Trial Comparative Study Clinical Trial
Regional anaesthesia for circumcision. Subcutaneous ring block of the penis and subpubic penile block compared.
In this prospective study techniques for the subcutaneous ring block of the penis and subpubic block of the penis for analgesia after circumcision were compared. Forty-five boys having circumcision as day-case patients were allocated randomly to have either a subcutaneous ring block or a subpubic penile block. The blocks were inserted after induction of anaesthesia but before surgery. ⋯ Four of the 24 boys who had subpubic penile blocks and nine of the 16 boys who had subcutaneous ring blocks were given morphine for post-operative pain (P = 0.015). The surgeons complained about oedematous tissues in three patients, all of whom had had subcutaneous ring blocks. The subpubic penile block provided significantly better analgesia than the subcutaneous ring block of the penis.

Randomized Controlled Trial Comparative Study Clinical Trial
The addition of opioids to local anaesthetics in brachial plexus block: the comparative effects of morphine, buprenorphine and sufentanil.
We compared the duration of analgesia produced by a mixture of lignocaine and bupivacaine, either alone or combined with morphine (75 micrograms.kg-1), buprenorphine (3 micrograms.kg-1) or sufentanil (0.2 microgram.kg-1) in 80 patients after brachial plexus block for orthopaedic surgery of the upper limb. The characteristics of analgesia were evaluated hourly using a visual analogue scale. ⋯ The median duration (range) of satisfactory analgesia was: 11.5 (8-15) h without an opioid, 21 (9-27) h with morphine, 20 (14-34) h with buprenorphine and 24.5 (11-38) h with sufentanil. We conclude that the addition of an opioid to a local anaesthetic mixture lengthens the duration of analgesia.

Incomplete sensory blockade of the foot after sciatic nerve block in the popliteal fossa may be related to the motor response that was elicited when the block was performed. We investigated the appropriate motor response when a nerve stimulator is used in sciatic nerve block at the popliteal fossa. ⋯ Inversion is the motor response that best predicts complete sensory blockade of the foot. Incomplete blockade of the sciatic nerve may be a result of the size of the sciatic nerve, to separate fascial coverings of the tibial and common peroneal nerves, or to blockade of either the tibial or common peroneal nerves after branching from the sciatic nerve.

Clinical TrialSuperficial and deep cervical plexus block for carotid artery surgery: a prospective study of 1000 blocks.
Cervical plexus blocks are performed for carotid surgery to allow neurological assessment of the awake patient. The aim of this study was to establish the frequency of success, complications, and patient acceptance of the technique. ⋯ We conclude that superficial and deep cervical plexus block has a high success rate, low complication rate, and high patient acceptance rate. Caution should, however, be exercised to ensure a low intravascular injection rate which is of most concern with this technique, because blood was aspirated in 30% of patients during performance of the block.
