Case ReportsAirway difficulty after a brachial plexus subclavian perivascular block.
We report a case of upper airway obstruction after subclavian perivascular block in a patient with a preexisting unrecognized paralyzed vocal cord on the opposite side. We discuss the incidence of vocal cord paralysis after subclavian perivascular block and the risk of airway compromise if contralateral vocal cord paralysis is known or suspected.

Comparative Study
Effect of dexamethasone on motor brachial plexus block with bupivacaine and with bupivacaine-loaded microspheres in a sheep model.
It has been suggested that dexamethasone potentiates the sensory block produced by bupivacaine when both drugs are loaded in microspheres. The aim of the study was to evaluate the effect of dexamethasone on the brachial plexus block obtained with plain bupivacaine and bupivacaine-loaded microspheres. ⋯ Despite the delayed onset of motor block, the incorporation of dexamethasone in bupivacaine-loaded microspheres dramatically increases the duration of action (700 +/- 485-5160 +/- 2136 min), which could be clinically relevant when such a drug-delivery system will be available.

Case ReportsThree in one block for unilateral knee arthrotomy in an old lady.
An old lady having septic arthritis of right knee joint underwent arthrotomy under three in one block for femoral, obturator and lateral cutaneous nerve of thigh in inguinal region, with catheter in situ. She was a case of chronic obstructive airway disease with ischaemic heart disease, so operation and postoperative pain management was planned under regional block. Anaesthesia was started by giving regional block with 0.25% bupivacaine at first and maintained with intermittent injection of 0.125% bupivacaine. The patient was pain free and comfortable though out the perioperative period.
