Bilateral tension pneumothorax complicating high-frequency jet injection ventilation during rigid open bronchoscopy for foreign body removal in a 3-year-old child is reported. Subcutaneous emphysema, bradycardia and low voltage of the QRS complex were the presenting symptoms. Disparition of heart dullness by percussion was the most suggestive clinical sign while auscultation of the breath sounds was not conclusive. It is stressed that tension pneumothorax is a potential life-threatening complication of high-frequency injection ventilation and should be promptly considered in any case of persistent cardiac deterioration during pediatric bronchoscopy.
据报道，一名3岁儿童在硬质开放支气管镜检查取异物过程中，高频喷射通气并发双侧张力性气胸。皮下气肿、心动过缓和QRS波群低电压为其临床表现。叩诊心浊音界消失是最具提示性的临床体征，而呼吸音听诊并无定论。需强调的是，张力性气胸是高频喷射通气潜在的危及生命的并发症，在小儿支气管镜检查期间，任何持续性心脏功能恶化的情况下均应迅速考虑到这一情况。
