Overview
The aim of this prospective randomized controlled study is to compare the effect of US-guided Recruitment Manauvere (RM) versus individualized positive end-expiratory pressure (PEEP) on oxygenation and preventing respiratory complications in pediatric patients undergoing laparoscopic abdominal surgeries.
Description
Atelectasis is among the most frequent postoperative pulmonary complications (PPCs) of general anesthesia with an incidence of between 68% and 100% in children. Atelectasis impairs gas exchange, thus causing hypoxemia and other respiratory disorders such as acute lung injury and pneumonia.
Pneumoperitoneum is another risk factor for perioperative atelectasis. It elevates the diaphragm and intra-abdominal pressure. In order to prevent atelectasis, applying positive end-expiratory pressure (PEEP) or an alveolar recruitment Maneuvere (RM) have shown beneficial effects.
Lung ultrasound (US) is a noninvasive, radiation-free, convenient, and reproducible bedside imaging modality for anesthesia-induced atelectasis in children.
