Local Anesthetic Infiltration During Pediatric Percutaneous Nephrolithotomy Improves Postoperative Analgesia

Abstract

Objective: Percutaneous nephrolithotomy is not pain-free due to the procedure itself and presence of post-operative diversion. Our purpose was to evaluate the efficacy of local anesthetic infiltration in postoperative analgesia in children who undergo percutaneous nephrolithotomy. Materials and Methods: Forty-two renal units were included to our study. Local anesthesia group received prilocaine and bupivacaine injection through the percutaneous access line where patients received no local anesthetic constituted the control group. All patients received the same anesthesia protocol and 15 mg/kg paracetamol infusion postoperatively four times a day. Post-operative pain scores of patients were evaluated by using FLACC-FPS scales. Patients with pain scores >= 4 received meperidine 1 mg/kg as rescue analgesic. Results: Between the two groups there was no significant difference in pain scores except 24th hour, where the local anesthesia group found to be favorable. The need (p=0.040) and total number (p=0.018) of rescue analgesic was significantly less in local anesthesia group. According to need for repetitive analgesic dose, the local anesthesia group was founded to be more advantageous (p=0.017). The postoperative analgesic satisfaction of parents' was favorable in local anesthesia group (p=0.002). Conclusion: In pediatric percutaneous nephrolithotomy, preemptive local anesthetic infiltration reduces postoperative pain, the need for analgesics, the number of analgesics used and also improves patient comfort and analgesic satisfaction.
