Summary

In anesthetized children, the incidence of lung collapse with episodes of hypoxemia is high. Diaphragmatic dysfunction induced by general anesthesia is one of the most important factors in the genesis of regional losses of lung aeration. The mass of the abdominal organs pushes the diaphragm cranially compressing the lungs in the most dependent areas. Such regional lung collapse may range from a slight loss of aeration to complete atelectasis.

Interventions

PROCEDURE

conventional recruitment maneuvers

The recruitment maneuver will be performed at 3 predefined time points: 5 minutes after induction of GA (T2), 5 minutes after insufflation of the capnoperitoneum (T3), After the end of surgery and before recovery from anesthesia (T4). by pressure controlled mode starting with an airway pressure of 15 cmH2O the subsquently changed ( decrease or increase) to provide targeted tidal volume according to each patient, maintaining end-tidal carbon dioxide between 35 to 45 mmHg with 5 cmH2O increments in PEEP until a peak pressure of 30 cmH2O will be achieved. Each PEEP level will be maintained for 5 s. The peak airway pressure will be maintained for 10 s or five breaths and subsequently reduced, followed by maintenance with the previous ventilator settings

PROCEDURE

ultrasound-guided recruitment maneuvers

* Ultrasound guided maneuver will be performed at T2, T3 and T4. * The recruitment maneuver will be performed under ultrasound guidance until no collapsed lung area is visible. The strategy to increase the airway pressure will be the same as that for the conventional maneuver, although the maximal pressure limit will be 40 cmH2O. The Recruitment maneuvers (RM) will be started searching the pressure level at which the consolidation pattern disappears and progressive lung re-aeration is observed and will be recorded for all patients (the lung's opening pressure).(14) Lung ultrasound examination will be performed every 5 cmH2O increments in PEEP to detect the lung's opening pressure.
