The Influence of Warm Bupivacaine on Supraclavicular Plexus Block Characteristics

3. november 2019 opdateret af: Mansoura University

The Influence of Bupivacaine Temperature on Supraclavicular Plexus Block Characteristics

Despite PH adjustment of local anesthetic solution improves the quality of the block in all respects with special advantage of early onset of sensory and motor block, adequate level of analgesia, and prolongation of duration of block, the effect of warmed bupivacaine should have the same effect which have not been evaluated on supraclavicular plexus block for upper limb surgery.

The warmed bupivacaine used in supraclavicular plexus block may reduce sensory and motor block onset and prolong the duration of analgesia when compared to bupivacaine at operating room temperature.

Detaljeret beskrivelse

The aim of this study is to compare the effect of warm bupivacaine 0.5% at 37◦C versus bupivacaine 0.5% at operating room temperature at 23◦C on ultrasound-guided supraclavicular plexus block characteristics as regard sensory block onset time, motor block onset time, duration of sensory and motor block , effective duration of analgesia, total analgesics requirement, complications and side effects.
