Comparative Study between Bupivacaine and Bupivacaine Plus Potassium Chloride for Brachial Plexus Block
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 3
Abstract
Background: Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. The prime duty of any anesthesiologist is to relive pain in the perioperative period. Today regional anesthesia is well established as equal to general anesthesia in effectiveness and patient acceptability. Regional anesthesia is blocking of peripheral nerve conduction in a reversible way using local anesthetic agents. Materials and Methods: Sixty patients of age group between 20 and 70 years of either sex of ASA Grade I and II category posted for various types of upper limb surgeries. The patients were randomly allocated into two groups. Supraclavicular brachial plexus block was performed. Group I (potassium group) – 30 ml of 0.375% bupivacaine with 0.2 mmol of potassium chloride (prepared by adding 0.1 ml of potassium chloride and 10 ml distilled water to 20 ml of 0.5% bupivacaine). Group II (plain bupivacaine group) received 30 ml of 0.375% bupivacaine only. The following parameters were observed after performing supraclavicular brachial plexus block in both groups: (1) The onset time of sensory and motor blockade. (2) The quality of sensory and motor blockade. (3) The duration of blockade. Result: The onset of sensory and motor blockade was early in potassium group when compared to plain bupivacaine group, the duration of the blockade was prolonged in potassium group when compared to other group, the quality of blockade was better in potassium group when compared to other group. Conclusion: The present study concludes that addition of potassium chloride to bupivacaine had a significant clinical advantage over plain bupivacaine on onset time, duration and quality of sensory and motor blockade in brachial plexus block.
