机械通气患者套囊压力的监测

目的 讨论机械通气患者气管插管导管、气管切开套管的套囊压力和注气量是否合适,提供正确给套囊注气的科学依据.方法 对35例气管插管、气管切开进行机械通气患者的气管套管套囊压力和注气量的实际值和理想值进行准确测量.结果 65％的患者气管套管套囊实际压力和注气量过高,大于理想值.其中套囊实际注气量大于理想注气量2～4ml,套囊压力超过理想压力2～26 cm H2O.结论 临床上大部分气管套管套囊压力和注气量偏高,因此,应对人工气道患者采用专用套囊测压仪指导套囊注气量及控制囊内压,最大限度地避免气道黏膜的损伤.

The influence of endotracheal tube cuff pressures to PEEP values in mechanical ventilated patients

Objective In cases of tracheal intubation of patients with a mechanical ventilation tube,measure trachootomy tube cuff pressure and the injection of gas whether it was providing appropriate pressure under the conditions of the use of gas injection basis.Methods In 35 cases of tracheal intubation,measure the endotracheal tube cuff pressure of mechanical ventilation patients with tracheotomy and note the actual value and the ideal gas value of accurate measurement.Results About 65％ of patients with tracheal tube cuff pressure and the actual injection gas were too high,greater than the ideal value.One cuff was greater than the actual injection gas ideal gas injection rate 2 ～4 ml,the pressure cuff pressure above the ideal of 2 ～ 26 cm H2 O.Conclusion Most of the clinical tracheal tube cuff pressure indicates too high gas injection,so doctors should use a dedicated artificial airway cuff pressure measuring instrument to guide and control cuff intracystic injection gas pressure in order to avoid possible damage of airway mucosa.
