How to choose a suitable intraabdominal pressure level during single-incision laparoscopic surgery in children

Laparoscopic surgery has become a common procedure in pediatric patients. However, adverse hemodynamic changes such as the increase of intraabdominal pressure (IAP) may occur laparoscopic surgery. The aim of this study is find a method to set a suitable IAP level in children before laparoscopic surgery. From Jan 2012 to Dec 2014, data were collected from a total of 1776 children needing laparoscopic high ligation of hernia sac. A retrospective data analysis was performed using a new defined variant Index A which had information of age, body mass index (BMI) and duration of pneumoperitoneum. The blood pressures (SBP and DBP) and the PaCO2 were increased but SV showed no changes in patients after CO2 insufflation. The complications were found in 32 cases including 2 cases with subcutaneous emphysemarelated to the CO2 insufflation directly, 3 cases of respiratory infection, 5 cases of incision infection and 2 cases of urinary tract infection) and technique related. Furthermore, the risks of complications were negatively associated with the Index A. An IAP can be optimal set up in laparoscopic high ligation of hernia sac by using the Index A.
