Major laparoscopic surgery under regional anesthesia: A prospective feasibility study

Abstract

Background: Laparoscopic surgeries have attained the status of a gold standard for most of the abdominal pathology; we therefore performed this study to assess feasibility and safety of major laparoscopic surgeries like laparoscopic cholecystectomy (LC) and laparoscopic assisted vaginal hysterectomy (LAVH)/total laparoscopic hysterectomy (TLH) under regional anesthesia that is combined spinal epidural anesthesia (CSE) with normal pressure pneumoperitoneum using intrathecal fentanyl with bupivacain.

Methods: In a zonal government hospital, 50 patients were selected prospectively for LC and LAVH/TLH, under normal pressure (12 mmHg) pneumoperitoneum and under CSE over a span of fifteen months. Injection bupivacaine (0.5%) and 20 μg of fentanyl were used for spinal anesthesia. Plain bupivacaine (0.5%) was used for epidural anesthesia.

Results: We successfully performed the operations in 48 patients without major complications. CSE was converted to general anesthesia in two patients due to distressing shoulder tip pain. Age varied between 25 and 70 years. Duration of operation time (skin to skin) was between 50 and 170 min. Five patients had urinary retention and one developed localized pruritis. There was no incidence of respiratory depression, aspiration or headache.

Conclusion: Laparoscopic surgeries with normal pressure CO2 pneumoperitoneum are feasible and safe under CSE. Incidence of postoperative shoulder pain was minimal due to use of intrathecal fentanyl and complications were less and easily manageable.
