Brief Summary

Anesthesia-induced atelectasis is a well-known entity observed in approximately 68-100% of pediatric patients undergoing general anesthesia. The collapse of dependent lung zones starts with anesthesia induction but can persist for hours or even days after surgery. Such anesthesia-related atelectasis has a number of negative clinical consequences such as the impairment of arterial blood oxygenation and lung mechanics as well as the predisposition for ventilator-associated lung injury. The adjustment of ventilator settings for preventing the occurrence of atelectasis and for reducing pulmonary complications remains controversial. Lung sonography (LUS) plays an important role in diagnosing pulmonary diseases in children, including atelectasis of different origins. LUS has demonstrated its high sensitivity and specificity for diagnosing anesthesia-induced atelectasis in children.

Outcome Measures

Primary Outcomes (1)

  • Compare lung aeration between protective mechanical ventilation and recruitment maneuvers in pediatric patients scheduled for abdominal laparoscopic surgery using ultrasound imaging and a four point aeration score to assess the lung aeration

    Compare lung aeration between protective mechanical ventilation and recruitment maneuvers in pediatric patients scheduled for abdominal laparoscopic surgery using ultrasound imaging and a four point aeration score (0: normal lung aeration, 1: moderate loss of lung aeration, 2: severe loss of lung aeration, 3: complete loss of lung aeration and lung consolidation).

    intraoperative

Secondary Outcomes (1)

  • Lung aeration score pre/post the recruitment maneuver during laparoscopic surgery

    intraoperative

Study Arms (2)

Control group

NO INTERVENTION

Patients received standard protective mechanical ventilation during all surgery, with tidal volumen 6 ml/kg and positive end-expiratory pressure (PEEP) level of 5 (centimeter of water) cmH2O.

Recruitment maneuver group

EXPERIMENTAL

Patient received a lung recruitment maneuver after pneumoperitoneum insufflation. The recruitment maneuver consists in 10 breaths at 30/15 cmH2O of plateau pressure and PEEP, respectively. Then, the ventilatory settings back to protective ventilation but adding 8 cmH2O of PEEP to keep the lungs open.

Other: Lung recruitment maneuver

Interventions

The lung recruitment maneuver consists in a brief and controlled increment in airways pressure (15 cmH2O of PEEP + 15 cmH2O of driving pressure) for 10 breaths.

Recruitment maneuver group
