Brief Summary

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.

Detailed 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.

Primary Outcome Measures
NameTimeMethod
Intraoperative oxygenationOne hour after second recruitment Maneuvere

Intraoperative oxygenation which will be assessed by P/F ratio (the ratio of arterial oxygen partial pressure (PaO2 in mmHg) to fractional inspired oxygen P/F ratio will be assessed before induction of anesthesia, one hour after pneumoperitoneum, and after second recruitment Maneuvere (RM)

Secondary Outcome Measures
NameTimeMethod
Mean arterial blood pressure (MAP)One hour after extubation

Mean arterial blood pressure (MAP) will be assessed before induction of anesthesia, immediately after intubation, after first recruitment Maneuvere (RM), one hour after pneumoperitoneum, after second recruitment Maneuvere (RM), and one hour after extubation.

Lung ultrasound scores24 hours after extubation

Lung ultrasound scores to assess anesthesia-induced atelectasis and will be performed immediately after intubation, one hour after pneumoperitoneum, one hour after extubation, and 24 hours after extubation

Heart rateOne hour after extubation

Heart rate (HR) will be assessed before induction of anesthesia, immediately after intubation, after first recruitment Maneuvere (RM), one hour after pneumoperitoneum, after second recruitment Maneuvere (RM), and one hour after extubation.

Postoperative pulmonary complication24 hours postoperative

Early postoperative pulmonary complication in the first 24 hours postoperative.
