The aim of our study is to assess the beneficial effect of sustained inflations as a recruitment manoeuvre, using LUS examinations, on the degree of lung atelectasis that occurs in pediatric patients undergoing laparoscopic surgery. Objectives * To assess the effect of general anaesthesia and capnoperitoneum on lung atelectasis in the paediatric patients by using LUS examination * To assess the effect of sustained inflations as a recruitment manoeuvre in decreasing lung atelectasis caused by general anaesthesia and capnoperitoneum by using LUS examination Hypothesis Our main hypothesis is that the use of repeated Sustained Inflation as a recruitment manoeuvre in pediatric patients undergoing laparoscopic surgery will result in decreased atelectasis compared to conventional ventilation.
