Randomized Controlled Trial Clinical Trial
Latency of brachial plexus block. The effect on onset time of warming local anaesthetic solutions.
A double-blind study was set up to investigate the effect of warming local anaesthetic solutions on the latency of onset of subclavian perivascular brachial plexus blocks. Twenty-four adult patients were randomly allocated into two equal groups. ⋯ The speed of onset of sensory blockade was significantly increased when the temperature of the local anaesthetic solution was increased to 37 degrees C. There were no adverse side effects in either group.

The ankle block is a safe and effective means of providing sensory anesthesia to the foot. The nerve supply to the foot at the level of the ankle is relatively superficial and consists of five nerve branches. The posterior tibial, which supplies the plantar aspect of the foot; the saphenous, supplying the medial portion of the foot; the deep peroneal, supplying an area between the great and second toes; the superficial peroneal, two branches supplying the majority of the dorsum of the foot; and the sural nerve, which supplies the lateral aspect of the foot. Using a small amount of local anesthesia, these nerves can be effectively anesthetized to prepare areas of the foot for surgical intervention.
