Atelectasis and lung recruitment in pediatric anesthesia: An educational review

Abstract General anesthesia is associated with development of pulmonary atelectasis. Children are more vulnerable to the development and adverse effects of atelectasis. We review the physiology and risk factors for the development of atelectasis in pediatric patients under general anesthesia. We discuss the clinical significance of atelectasis, the use and value of recruitment maneuvers, and other techniques available to minimize lung collapse. This review demonstrates the value of a recruitment maneuver, maintaining positive end‐expiratory pressure (PEEP) until extubation and lowering FiO 2 where possible in the daily practice of the pediatric anesthetist.
