Abstract：
Patients with acute respiratory distress syndrome due to COVID-19 require intensive care unit (ICU) admission with consecutive endotracheal intubation and invasive mechanical ventilation. In patients with long-term mechanical ventilation, percutaneous dilatational tracheostomy (PDT) may be considered. This retrospective analysis includes clinical data on patients treated at the ICUs of the COVID Hospital of the Clinical Center of Vojvodina in the period from September 3, 2021 to May 1, 2022, and underwent PDT. Patients were predominantly male (n=48; 65.8%). Weaning from mechanical ventilation was achieved in 31 (42.5%) and decannulation in 25 (34.2%) patients. The mean time from polymerase chain reaction SARS CoV-2 positivity until PDT was 15.59±6.85 days. The mean time of endotracheal intubation before the PDT procedure was 7.37±4.89 days. The mean weaning time from mechanical ventilation was 10.45±7.92 days. Twenty-five (34.2%) patients were decannulated at the mean time of 19.60±11.81 days. The complications were tracheostomy related bleeding (2 patients), pneumothorax (4 patients), subcutaneous emphysema (1 patient) and cricoid cartilage injury (1 patient). PDT is a simple, safe, and effective procedure performed in COVID-19 patients in the ICU.
摘要：
因COVID-19引起的急性呼吸窘迫综合征患者需要接受重症监护病房（ICU），并连续气管插管和有创机械通气。长期机械通气患者,可考虑经皮扩张气管造口术(PDT).这项回顾性分析包括2021年9月3日至2022年5月1日期间在伏伊伏丁那临床中心COVID医院ICU接受治疗并接受PDT的患者的临床数据。患者主要为男性（n=48；65.8%）。31例（42.5％）患者实现了机械通气撤机，25例（34.2％）患者实现了拔管。从聚合酶链反应SARSCoV-2阳性到PDT的平均时间为15.59±6.85天。PDT术前气管插管的平均时间为7.37±4.89天。机械通气的平均撤机时间为10.45±7.92天。25例（34.2％）患者平均拔管时间为19.60±11.81天。并发症为气管切开相关性出血(2例),气胸（4例），皮下气肿（1例）和环状软骨损伤（1例）。PDT是一个简单的，安全,和ICU中COVID-19患者的有效程序。
