Background and aim Pain following laparoscopy is mostly because of irritation of the diaphragm and stretching of the peritoneum associated with carbon dioxide insufflation. In this study, we evaluate the effectiveness of periportal xylocaine infiltration and intraperitoneal instillation of l-bupivacaine at the beginning of laparoscopy in pediatrics in reducing postoperative pain, delaying the onset and reducing the total dose of rescue analgesia, and improving perioperative hemodynamics. Patients and methods After receiving ethical committee approval in Kasr Al Ainy University Hospital and parents' consent, 40 ASA I and II children were allocated randomly to two groups. In group I, l-bupivacaine 0.5% instilled into the peritoneal cavity immediately after gas insufflation at a dose 2 mg/kg. In group II, normal saline was instilled instead of l-bupivacaine. All patients were subjected to preincisional periportal lidocaine 1% infiltration. Heart rate (HR) and blood pressure were recorded at 5 min intervals starting from the preoperative period until 6 h postoperatively. The Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) score was used, and the onset and dose of pethidine were recorded. Results HR was lower in group I and HR4 was significantly lower (P < 0.001). The mean arterial blood pressure (MAP) was also lower in group I. It was significantly lower in MAP3 and MAP4 (P = 0.049 and 0.004, respectively). The median pain score was significantly lower in group I (P = 0.001). Onset of rescue analgesia demand was longer in group I and the total dose of pethidine was significantly lower in group I (P < 0.001). Conclusion Periportal lidocaine infiltration and intraperitoneal l-bupivacaine instillation in pediatric laparoscopy, after pneumoperitoneum, reduced postoperative pain and improved perioperative hemodynamics.
