Brief Summary

Background: We performed this prospective clinical study to compare the post-operative recovery profile of our patients after transperitoneal and retroperitoneal laparoscopic nephrectomy techniques. Our primary aim was to compare post-operative epidural analgesic consumption of transperitoneal (Group T) and retroperitoneal (Group R) laparoscopic nephrectomy patients within the first 24 hours. Methods: Forty-four patients scheduled for elective transperitoneal or retroperitoneal laparoscopic nephrectomies were enrolled. All patients in both groups received epidural catheter, 2.5ml test dose of lidocaine 2% and general anesthesia induction. At the end of the surgery, patients were given 1g IV paracetamol and 10ml 0.25% bupivacaine through epidural catheters and extubated. In the post-operative care unit, patients started to receive a continuous infusion of 0,1% bupivacaine and 1µg/ml fentanyl 5ml/h with patient-controlled boluses of an additional 4ml by a patient controlled epidural analgesia (PCEA) device. They were prescribed IV tramadol 1mg/kg as a rescue analgesic (Visual analog scale (VAS)≥4). Total analgesic consumptions from PCEA devices, VAS scores at rest and during mobilization, heart rates (HRs), systolic (SBPs)/diastolic blood pressures (DBPs) at extubation (0th min-basal) and at post-operative 30th min, 2nd, 6th, 12th, 18th and 24th hours as well as number of patients who require rescue analgesic were recorded. Nausea, vomiting, time to first mobilization, return of bowel sounds and hospital stay were also documented.

Study Arms (2)

Transperitoneal laparoscopic nephrectomy

ACTIVE COMPARATOR

Patients in this group underwent transperitoneal laparoscopic nephrectomy in 45-60º modified flank position after receiving epidural catheter in the sitting position before the surgery.

Drug: Transperitoneal laparoscopic nephrectomy

Retroperitoneal laparoscopic nephrectomy

ACTIVE COMPARATOR

Patients in this group underwent retroperitoneal laparoscopic nephrectomy in lateral decubitis position after receiving epidural catheter in the sitting position before the surgery.

Drug: Retroperitoneal laparoscopic nephrectomy

Interventions

After the surgery: 10 ml 0.25% bupivacaine through epidural catheters before extubation and continuous infusion of 0,1% bupivacaine and 1 µg/ml fentanyl 5 ml/h with patient-controlled boluses of an additional 4 ml, with a lockout time of 20 min and 4-h limit of 30 ml by a patient controlled epidural analgesia (PCEA) device

Also known as: Patient controlled epidural analgesia (PCEA)
