EFFECT OF POTASSIUM CHLORIDE AS A LOCAL ANAESTHETIC ADJUVANT FOR SUPRACLAVICULAR BRACHIAL PLEXUS BLOCK FOR UPPER LIMB SURGERIES
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2016, Vol 5, Issue 15
Abstract
BACKGROUND Supraclavicular brachial plexus block is a popular and widely employed regional nerve block technique. It provides safe, effective, low cost anaesthesia along with prolonged post-operative analgesia. Administration of adjuvant along with the local anaesthetic helps in prolonging the pain free period. This study was designed to compare the effect of plain bupivacaine and addition of potassium chloride to bupivacaine in brachial plexus block. METHODS This was a prospective, double blind study in which 60 patients of ASA 1 and 2, aged 20 to 70 years undergoing elective and emergency upper limb surgeries done in Father Muller Medical College Hospital. They were randomly selected and divided into 2 groups to receive 0.375% bupivacaine with 0.2mmol of potassium chloride (group-K) and 0.375 bupivacaine (group-B). Anaesthetist who took no part in brachial block prepared the study drug. Spontaneous breathing was preserved using face mask. The analgesic onset, duration of analgesia, sensory and motor blockade was compared and any adverse event were recorded and treated. Collected data was statistically analysed by student âtâ test and Chi square test. RESULTS Group-K had a faster onset of sensory and motor blockade, prolonged duration of action than group-B. Quality of blockade was better in adjuvant added group-K. CONCLUSION Potassium chloride as an adjuvant to bupivacaine has advantages in supraclavicular brachial plexus block for upper limb surgeries.
