该研究旨在评价接受连续声门下气道分泌物抽吸(CASS)的气管插管患者在机械通气(MV)最初8天内发生肺炎的潜在危险因素。 方法 83例气管插管患者,MV最初8天内发生肺炎者作为实验组,无肺炎发生者作为对照组。所有患者均经口气管插管,气囊内压每4小时监测1次,使之保持在2.67kPa(20mmHg)以上;对声门下分泌物行 The aim of this study was to evaluate the potential risk of developing pneumonia in the first 8 days of mechanical ventilation (MV) in endotracheal intubation patients undergoing continuous subglottic airway aspiration (CASS). Methods 83 cases of tracheal intubation patients, MV within the first 8 days of onset of pneumonia as experimental group, no pneumonia as a control group. All patients were orotracheal intubation, balloon pressure monitoring once every 4 hours to keep it at 2.67kPa (20mmHg) above; on the subglottic discharge
