Background: The analgesic efficacy of peri-incisional infiltration and intraperitoneal instillation of ropivacaine in laparoscopic donor nephrectomy has not been clearly established.
Methods: This randomized, controlled, double-blind trial allocated living donors undergoing left-sided laparoscopic donor nephrectomy to one of the following 4 groups: peri-incisional normal saline (NS) and intraperitoneal NS (group A, n = 30), peri-incisional 0.375% ropivacaine and intraperitoneal NS (group B, n = 31), peri-incisional NS and intraperitoneal 0.15% ropivacaine (group C, n = 31), and peri-incisional 0.375% and intraperitoneal 0.15% ropivacaine (group D, n = 32). Pain status was assessed using the visual analog scale at rest and during coughing at 2, 12, 24, and 48 hours postoperatively. Patient-controlled analgesia and additional rescue analgesic consumption were calculated by conversion to an equivalent dosage of morphine. This study did not include prisoners or those individuals who were coerced or paid as study participants.
Results: The patient demographics and perioperative outcomes, including operative time, blood loss, and incision length, were comparable between the groups. The pain scores and number of patients who experienced shoulder pain at all postoperative time points did not differ significantly among the 4 groups. Postoperative analgesic consumption was similar in all groups, and there was no difference in the length of hospital stay.
Conclusion: Peri-incisional infiltration and intraperitoneal instillation of ropivacaine did not reduce postoperative pain or analgetic consumption.
