Evaluation of the Effectiveness of Local Anesthetic Agent Infiltration into Port Sites at Preoperative Period with It's Correlation to Post Operative Analgesia in Laparoscopic Surgical Procedures-A Retrospective and Comparative Study

Background: Postoperative pain management remains a significant challenge in laparoscopic surgery despite its minimally invasive nature. This study aimed to evaluate the effectiveness of preoperative local anesthetic infiltration at port sites and its correlation with postoperative analgesia requirements in laparoscopic procedures. Methods: This retrospective comparative study analyzed data from 52 patients who underwent elective laparoscopic procedures. Patients were divided into two groups: Group A (n=26) received preoperative port-site infiltration with 0.5% bupivacaine, while Group B (n=26) did not receive local anesthetic infiltration. Postoperative pain scores, analgesic requirements, recovery parameters, and patient satisfaction were compared between the groups. Results: Patients who received preoperative local anesthetic infiltration demonstrated significantly lower visual analog scale pain scores at all time points during the first 24 postoperative hours compared to the control group (p<0.001). The time to first analgesic request was significantly prolonged in Group A (210.4 ± 45.3 min vs. 78.2 ± 25.6 min, p<0.001), and total tramadol consumption was reduced by 50% (73.1 ± 26.5 mg vs. 146.2 ± 38.7 mg, p<0.001). Group A also showed earlier ambulation (5.2 ± 1.1 vs. 7.8 ± 1.6 hours, p<0.001), shorter PACU stay (42.7 ± 10.3 vs. 58.4 ± 13.7 min, p<0.001), and lower incidence of postoperative nausea and vomiting (15.4% vs. 42.3%, p=0.033). Patient satisfaction was significantly higher in the local anesthetic group, with 84.7% rating their pain management as "excellent" or "good" compared to 46.2% in the control group (p=0.002). Conclusion: Preoperative local anesthetic infiltration at port sites significantly reduces postoperative pain, decreases analgesic requirements, and improves recovery parameters in patients undergoing laparoscopic procedures. This simple, safe, and cost-effective technique should be considered as a routine component of multimodal ...
