Abstract

Purpose: To evaluate the efficacy of intraoperative local anesthetic infiltration in combination with intravenous paracetamol infusion on postoperative pain management in patients who underwent percutaneus nephrolithotomy (PCNL). Patients and Methods: Sixty adult patients were randomized into three groups with 20 cases in each: Group SP, 20mL saline was infiltrated through the whole nephrostomy tract intraoperatively and this was followed by intravenous paracetamol (4 x 1 g) infusion postoperatively; group LP, 20mL of 0.25% levobupivacaine infiltration to the nephrostomy tract followed by intravenous paracetamol infusion; Group LS, 20mL of 0.25% levobupivacaine infiltration to the nephrostomy tract followed by intravenous saline infusion. In the postoperative period, the pain status of patients was evaluated at postoperative 6 and 24 hours by using the visual analogue scale (VAS). In patients who did not completely respond, meperidine (1mg/kg intramuscularly) was administered as an additional "rescue'' analgesic. Patient satisfaction from the postoperative analgesia management was assessed by a 5 point scale. Results: There was no statistically significant difference between the three groups regarding the demographic characteristics, surgical complications, and postoperative hospital stay. Our findings revealed that in group LP, the amount and frequency of opioid used and related side effects was lesser, VAS score was lower, time to full mobilization was shorter, and the patient satisfaction score was higher when compared with the other two groups. Conclusion: Levobupivacaine infiltration through the nephrostomy tract in combination with intravenous paracetamol infusion was shown to be safe and efficacious as an analgesia method after PCNL.
