Comparative Study
Axillary brachial plexus block--an underused technique in the accident and emergency department.
To compare axillary brachial plexus block and Bier's block as methods of providing upper limb anaesthesia. ⋯ Brachial plexus blocks are an alternative form of providing upper limb anaesthesia in the accident and emergency department. They are relatively simple to perform, well tolerated by patients, and have the advantage of providing prolonged analgesia without the need for additional medication.

Randomized Controlled Trial Clinical TrialContinuous axillary brachial plexus block for postoperative pain relief. Intermittent bolus versus continuous infusion.
The aim of this study was to compare the efficacy and safety of continuous axillary brachial plexus block by infusion and by intermittent injection of bupivacaine 0.25% in the management of postoperative pain. ⋯ Overall, both techniques provided safe and effective postoperative analgesia. As compared with continuous infusion, intermittent bolus administration resulted in lower plasma bupivacaine levels despite similar infusion rates.

Bilateral trigeminal nerve palsy during an extensive lumbar epidural block.
A rare case of trigeminal nerve blockade arising in the course of obstetric lumbar epidural anaesthesia is described. There was extensive bilateral spread of nerve-block up to the C4 level with respiratory distress after top-up for caesarean section, and subsequent epidurography revealed high epidural spread of contrast. The mechanism of the trigeminal nerve palsy was the source of some controversy, particularly as to whether intracranial spread of local anaesthetic had occurred, possibly following accidental subdural or subarachnoid injection.

Distribution of local anesthetic solution in retromediastinal block. Preliminary experimental results.
Interpleural anesthesia blocks pain perception from the thoracoabdominal wall without impairment of leg function. Bilateral interpleural anesthesia is not recommended because of possible bilateral impairment of respiratory function. Infiltration of the retromediastinum with local anesthetic might cause bilateral thoracoabdominal somatic block and block of sympathetic afferents from the abdominal cavity without impairing respiration. ⋯ Block of pain perception from the abdominal wall and cavity is possible by injection of local anesthetic into the retromediastinum via a catheter introduced through the esophageal diaphragm hiatus. The block would not be expected to impair respiratory or leg function. Its efficacy and safety have yet to be established.
