Effect of Sustained Inflations on Lung Atelectasis During Pediatric Laparoscopic Surgery

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.ObjectivesTo assess the effect of general anaesthesia and capnoperitoneum on lung atelectasis in the paediatric patients by using LUS examinationTo assess the effect of sustained inflations as a recruitment manoeuvre in decreasing lung atelectasis caused by general anaesthesia and capnoperitoneum by using LUS examinationHypothesis 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.
