Abstract

Pain is an unpleasant experience associated with tissue damage. Peripheral tissue injury results in functional disturbances in the nervous system. Modern anaesthesiologists are not only concerned about pre-operative and intra operative care of the patient but also with postoperative welfare of the patient. In present study we have compared the efficacy of injection Bupivacaine 0.25% infiltration preoperatively versus postoperatively on duration of postoperative analgesia, VAS at the onset of pain, total analgesia requirement in 24 hours. 150 patients belonging to ASA Class I and II between the age of 15 and 75 who underwent lower abdominal surgeries belonging to either sex were included in the study. The patients were randomly allocated to three groups. Control Group(C) received 20ml normal saline, preoperative group (A) received 0.25% bupivacaine before incision, postoperative group (B) received 0.25% bupivacaine before closure. Duration of analgesia, VAS score at the time of first request of analgesia and total doses of analgesia over 24hrs were recorded. The total analgesia requirement was reduced over 24 hours in the group B in which the infiltration was done postoperatively.
