Negative Pressure Pulmonary Edema (NPPE) Following Extubation from Laryngeal Mask Airway-Case Report

脫離喉罩式呼吸道(LMA)後之急性負壓肺水腫

摘要


術後急性肺水腫是一種無法預測卻是危險的併發症,在第一時間做出正確診斷和治療是十分重要的。因為喉部痙攣引起上呼吸道阻塞是造成急性負壓肺水腫最常被廣泛討論的,而又以"年輕健壯男性"被認為是此併發症的好發族群。我們報告一位年輕健壯男性術後脫離喉罩式呼吸道(LMA)之急性負壓肺水腫,推測起因於使用喉罩式呼吸道所導致喉部痙攣,而最近的上呼吸道感染也是引發因子,病患成功地以利尿劑和連續正壓呼吸器(CPAP)治療出院。臨床醫師對於此併發症應審慎評估。(胸腔醫學2012;27:112-116)

並列摘要


Acute negative pressure pulmonary edema (NPPE) has been reported as an unpredictable but dangerous clinical event. Its occurrence is typically due to an upper airway obstruction related to laryngospasm. We herein present a case of acute NPPE related to laryngospasm in a healthy young male patient ventilated via laryngeal mask airway (LMA). The laryngospasm that the patient developed was most likely an outcome of stimulation associated with LMA extubation. A history of recent upper respiratory tract infection (URI) also may predispose to laryngospasm. The patient was successfully managed with diuretics and continuous positive airway pressure (CPAP).Clinicians should be aware of these complications when utilizing LMA.
