“…11,12 Some authors have suggested simply pouring local anesthetics into the abdominal cavity, as the majority of the patient's pain in the postoperative period does seem deep in the abdomen following laparoscopy. 13 Some authors have discussed that this method may decrease patient safety as abdominal anesthetics likely have higher intravascular absorption than other methods of administration. 14 Cases of toxicity have been reported, a specific syndrome of local anesthetic systemic toxicity (LAST) has been described.…”

Objective: We set out to evaluate whether the instillation of bupivacaine versus a saline solution into the peritoneal cavity at time of laparoscopic gynecologic surgery will reduce postoperative pain and postoperative opioid consumption. Data Sources: We searched six databases: Web of Science, SCOPUS, Cochrane CENTRAL, ClinicalTrials.Gov, MEDLINE and PubMed. Our search strategy had no restriction on time or languages and included all studies that met our search algorithm up to March of 2021. Methods of Study Selection:We included only randomized trials that met our search strategy for the outcomes of 1) pain intensity 24 hours after surgery, 2) pain intensity 6 hours after surgery, and 3) length of hospital stay. Tabulation, Integration, and Results: We analyzed continuous data using mean difference (MD) with relative 95% confidence interval (CI). We included 8 randomized clinical trials. We found that intraperitoneal bupivacaine showed significant difference from the saline group regarding pain intensity 24 hours after surgery (MD= −0.73 [−1.10, −0.36]) (P = 0.01) and pain intensity 6 hours after surgery (MD= −1.12 [−2.22, −0.02]) (P = 0.05). Overall, patients allocated to the placebo group seemed to need other analgesics earlier than patients allocated to the bupivacaine group (MD=145. 08 [51.37, 238.79] (P = 0.02)). There was no significant difference regarding the length of hospital stay (MD= −0.44 [−1.44, 0.56]) (P = 0.39). Conclusion: Bupivacaine significantly reduced the visual analog pain score for pain compared with that of the placebo at 6 and 24 hours postoperatively. There was no significant difference in hospital stay. Prospero Registration: CRD42021254268.
