Effects of Intrapulmonary Percussive Ventilation on Atelectasis in Critically Ill Pediatric Patients / 대한마취과학회지

ABSTRACT

Thirty six pediatric patients who were diagnosed as pulmonary atelectasis by chest radiography were managed with one of the following techniques for the treatment of atelectasis 1) intermittent positive pressure breathing (IPPB) with extrathoracic chest percussion and vibration, 2) IPPB and intrapulmonary percussive ventilation (IPV) and 3) IPV only. Chest X-ray films and arterial pH, Pco, and Po, were obtained for all patients in the morning and the afternoon. And systolic and diastolic blood pressure and heart rate were measured at that time. Alveolar arterial oxygen tension difference was calculated from inspired oxygen fracton and arterial oxygen tension. The rate of treatment of atelectasis was significantly low in the patients with IPPB and chest physiotherpy. But the durations for the treatment were not significantly different among the three groups. There were no significant differences in blood pressures, heart rates and artrial blood gases between pre-treatment and post- treatment states in all groups.
