Effectiveness of Local Bupivacaine Wound Infiltration in Post-Operative Pain Relief After Caesarean Section
Objective: The objective of my study is to compare local bupivacaine wound infiltration with placebo during caesarean section under spinal anaesthesia in terms of mean pain scores and analgesia requirement
Study Design: Randomized Controlled Trial
Place and Duration: Department of Gynaecology and Obstetrics, Benazir Bhutto Hospital, Rawalpindi, all patients admitted from OPD, Emergency and from High Risk Ward from 16 February 2013 to 15 August 2013.
Results: In our study, 86%(n=43) patients in Group-A and 82%(n=41) of patients in Group-B were between 18-30 years of age, while 14%(n=7) in group A and 18%(n=9) in Group-B were between 31-45 years, mean+sd was calculated as 26.52+4.54 in Group-A and 26.88+4.16 in Group-B. Comparison of pain score in both groups was recorded which was 1.98+0.91 in Group-A and 2.8+1.23 in Group-B, p value was calculated as 0.00026, which shows a significant difference between the two groups. In addition, the comparison of requirement of analgesia in both groups reveals that in Group-A 32.00mg+51.27 and in Group-B 82.00mg+84.97 of tramadol was administered on demand, p value was calculated as 0.00057, which shows a significant difference between the two groups.
Conclusion: We concluded that local bupivacaine wound infiltration is significantly effective as compared to placebo in postoperative pain relief and decreases analgesia requirement after caesarean section.
