摘要 目的通过测量人工气道机械通气患者不同体位时的气囊压力,为患者采取合适的体位,正确的气囊测压时机提供科学的临床依据。 方法40例经口气管插管机械通气患者,采用自身对照设计方案,应用一次性压力传感器测压,每位患者从初始位置半卧位30°开始,气囊压力调整为25 cmH2O(1 cmH2O=0.098 kPa),按顺序半卧位45°,左侧卧位30°,左侧卧位45°,右侧卧位30°,右侧卧位45°,平卧位,测量通气末的气囊压力。 结果气囊压力值在半卧位30°时是25 cmH2O,半卧位45°时、左侧卧位30°时、左侧卧位45°时、右侧卧位30°时、右侧卧位45°时、平卧位时分别是(28.55 ± 5.41)、(31.43 ± 7.42)、(32.20 ± 6.85)、(29.43 ± 5.84)、(29.20 ± 6.42)、(27.15 ± 4.05)cmH2O。半卧位30°时,气囊压力最低,虽然与平卧位气囊压力比较差异无统计学意义(t=-1.70,P=0.09),但平卧位时也有8例患者气囊压力〉30 cmH2O。半卧位30°与左侧卧位30°和右侧卧位30°比较差异有统计学意义(t=-5.09、-3.51,P〈0.01)。半卧位30°与左侧卧位45°和右侧卧位45°比较差异有统计学意义(t=-5.71、-3.33,P〈0.01)。当半卧位30°气囊压力调整为25 cmH2O时,改变体位后其他体位均有部分患者气囊压力〉30 cmH2O。 结论对于人工气道机械通气患者体位改变可以造成气囊压力的变化,这需要我们在临床护理中患者体位改变后及时测量和调整气囊压力。 ObjectiveTo measure endotracheal cuff pressure in different positions for mechanically ventilated patients, to provide clinical evidence in choosing suitable body position and measuring time. MethodsA total of 40 orally intubated and sedated patients were positioned in a neutral starting position (30°of semirecumbent position) with cuff pressure at 25 cmH2O (1 cmH2O=0.098 kPa), then 6 changes in position were performed: 45°of semirecumbent position, and left and right lateral positioning over 30° and 45°, horizontal position. Once a patient was correctly positioned, cuff pressure was measured and recorded. ResultsThe cuff pressure of different position were 30°of semi recumbent position (25 cmH2O, 45° of semi recumbent position (28.55 ± 5.41) cmH2O, 30° of left lateral position (31.43±7.42) cmH2O, 45°of left lateral position (32.20±6.85) cmH2O, 30°of right lateral position (29.43±5.84) cmH2O, 45°of right lateral position (29.20±6.42) cmH2O, horizontal position (27.15±4.05) cmH2O. The cuff pressure of semi recumbent position at 30°and horizontal position was no statistical significance in the difference (t=-1.70, P=0.09), but horizontal position had 8 patients′ cuff pressure more than 30 cmH2O. The cuff pressure of semi recumbent position at 30° was significantly lower than those of semi recumbent position at 45°, left and right lateral position (t=-5.71-3.33, P〈0.01). When the cuff pressure of 30° of semi recumbent position was 25 cmH2O, the other body positions had some patients' cuff pressure more than 30 cmH2O. ConclusionsChanging body position can affect the endotracheal tube cuff pressure, suggesting that endotracheal tube cuff pressure should be measured after changing patient′s position and adjusted within the recommended range.
