[Clinical efficacy of one-lung ventilation in treatment of children postoperatively intractable atelectasis].

Objective: To investigate the effect of fiberoptic bronchoscope-guided one-lung ventilation (OLV) on treatment of intractable atelectasis in children. Method: This retrospective cohort study was conducted in Pediatric Intensive Care Unit, Children's Hospital of Chongqing Medical University from December 2014 to May 2017. Six patients with intractable atelectasis of left lung were included. Three cases were male and three female with the age from 1.5 to 11.0 years. The endotracheal tube was intubated to the left main bronchus for OLV by the guidance of fiberoptic bronchoscopy. The effect of treatment by monitoring the chest imaging after treatment was evaluated. Result: Six pediatric patients were successfully cured by OLV. The duration of OLV ranged from 1.5 to 30.0 hours, and the intervals of OLV were usually 3 to 5 days. Each patient received 6 to 20 OLV treatments. Chest images showed the left lung reexpanded obviously after OLV treatments. Five patients successfully weaned from invasive ventilation and were discharged. Another patient turned better, discharged from hospital with noninvasive ventilation and weaned from noninvasive ventilation one month later after discharge. During the procedure of OLV, the vital signs of all patients were stable and no complication occurred. Conclusion: OLV with selective bronchial intubation guided by fiber bronchoscope is a safe and effective treatment for intractable atelectasis in children.
