Lung Recruitment and Postoperative CPAP

Lung Recruitment and Postoperative CPAP in Pediatric Laparoscopic Surgery

General anesthesia lowers FRC thereby promoting airway closure and absorption atelectasis. Alveolar recruitment manoeuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation.

General anesthesia lowers FRC thereby promoting airway closure and absorption atelectasis. Alveolar recruitment manoeuvers recruit collapsed alveoli, increase gas exchange, and improve arterial oxygenation. However, the effect of recruitment manoeuvre is short lasting and does not extend to the post operative period. Postoperative CPAP keeps the lung open and can improve oxygenation in the early postoperative period.

Inclusion Criteria:

• Pediatric patients undergoing laparoscopic surgery for abdominal cryptorchidism.

Exclusion Criteria:

• Cardio-respiratory illness.
• Unsatisfactory preoperative peripheral arterial oxygen saturation.
• Unsatisfactory preoperative hemoglobin level.
• Neurological or psychiatric disease.
• Children with a BMI >95th percentile for age.
