A comparative study of pre-incisional and post-incisional wound infiltration of bupivacaine for post-operative pain relief in abdominal surgeries
Journal Title: Medpulse International Journal of Anesthesiology - Year 2018, Vol 8, Issue 2
Abstract
Background:Topical infiltration of local anaesthetic in the surgical site is a simple, easy and attractive technique recommended for providing a longer post-operative pain free period and decreased opioid requirements.Materials and Methods: 50 adults (20-50yrs) scheduled for lower abdominal surgeries under general anaesthesia, were enrolled into 2 equal groups in this prospective, randomized and double-blind study. Group-I receivedinfiltration of20 ml of 0.25% Bupivacaine before skin incision while Group-II received the same as wound infiltration before skin closure. Post-operatively patients were assessed for severity of pain at 2, 4, 6, 8, 10, 16, 20and 24 hours according to Visual AnalogueScale (VAS).Also patients were observed for duration of analgesia, total no. of doses of Diclofenac sodium required for 24 hours, vital parameters and any complications. Data was analyzed using Chi-square and unpaired t-test.Results: Up to 6 hours all the patients in Group-I and Group-II had no pain to mild pain but after 8 hours all patients in Group-I while only 6 patients in Group-II had mild pain which was statistically significant. After 10 hours statistically, significant no. of Group-II patients had moderate to severe pain compared to Group-I. The mean duration of analgesia in Group I was 9.6± 1.1 hours while it was 8 ±0.8 hours in Group-II which was statistically significant. Total no. of analgesic doses required post-operatively was 1.5 ± 0.34 in Group – I while it was 2.4 ± 0.3 in Group – II which was again statistically significant. There was a significant increase in the vital parameters at 10 hours in group I patients. There was significant increase in vital parameters at 8, 16 and 24 hrs in group II patients.Conclusion: Our study confirms the belief that pre-incisional surgical wound infiltration facilitates a smooth and pain-free transition into post-operative period.
