Does Local Infiltration of Anesthesia Reduce Port-site Pain in Gynecological Laparoscopic Surgeries? A Pilot Study

Abstract

Abstract Objectives: The objectives of this study were to evaluate the visual analog scale (VAS) score in patients receiving port-site bupivacaine infiltration in gynecological laparoscopic surgeries and to compare it with those receiving placebo and to evaluate the additional analgesic requirement in the first 24 h after surgery. Materials and Methods: A prospective interventional study was conducted on 60 women scheduled for benign gynecological laparoscopic surgeries. Patients were randomized into two groups using an alternative sequential method of allocation. Approval from the Institute’s Ethics Committee was sought. Informed written consent was taken from all the patients. All laparoscopic surgeries were performed under general anesthesia. Double-blinding was done. A VAS with a 10 cm vertical score ranging from “no pain” to “worst possible pain” was used to assess the postoperative pain when the patient awakened in the operating room (2 h after surgery), then after 6 and 24 h. The primary outcome measured was pain perception by the patient (as VAS scores), and the secondary outcome was the need for additional analgesia. Results: Comparison of both groups with the VAS score shows P > 0.001, i.e., nonsignificant in all the groups. Additional analgesics were required in 56% of the patients in the intervention group and 60% of the patients in the control group; however, 44% and 40% of the patients from the intervention and control groups, respectively, do not require any additional analgesic in the postoperative period. Conclusion: The local infiltration of bupivacaine does not significantly reduce the port-site postoperative pain in gynecological laparoscopic surgeries.
