The duration of action of bupivacaine, levobupivacaine, ropivacaine and pethidine in peripheral nerve block in the rat.
There is a current interest in local anaesthetic drugs/formulations exhibiting long durations of sensory block and minor motor-blocking effects. ⋯ Equimolar doses of the investigated local anaesthetics exerted similar durations of sensory blockade in a peripheral nerve block model in the rat.

Randomized Controlled Trial Comparative Study Clinical TrialComparison between single injection transthecal and subcutaneous digital blocks.
A randomized double blinded study was performed on 142 patients to evaluate two different techniques of single injection digital anaesthesia. In group A, 86 digits in 71 patients were anaesthetized by a single injection transthecal technique using 3 cc of lignocaine and bupivacaine mixture. ⋯ Total anaesthesia of the digit was achieved in 75 (94%) digits. These two techniques were found to have no differences in effectiveness, distribution, onset and duration of anaesthesia.

The use of continuous paravertebral analgesia was studied in 15 children with a mean age of 9.8 years (2-16 years). Nine patients received pre-emptive and postoperative paravertebral analgesia while six children studied earlier in the series received only post operative paravertebral analgesia. ⋯ There were no pulmonary complications and no complications related to the continuous paravertebral infusion of bupivacaine. We conclude that continuous paravertebral block is an effective and safe method for post thoracotomy pain relief in children.
