最小闭合容量技术在人工气道气囊管理中的应用

Application of minimal closing capacity technology to artificial airway aerocyst administration

目的通过比较最小闭合容量技术(MOV)与压力表测量法(CPM)对危重症患者机械通气时的气囊压力及并发症的影响,探讨最小闭合容量技术在人工气道气囊管理中的应用。方法将118例压力表监测气囊压力﹥30 cm H2O(最小闭合容量充气后)的患者随机分成两组;对其导管气囊管理,分别采用MOV和CPM。结果充气时间、气囊内实际压力、听诊法的漏气发生率、误吸发生率在两组间的差异均有统计学意义(P<0.05)。各组的初次气囊充气压力、注气4 h及8 h后压力的差异均有统计学意义(P<0.05)。结论最小闭合容量技术能降低气囊漏气及并发症的发生率。

Objective To investigate the Application of minimal closing capacity technology to artificial airway aerocyst administration by comparing the effect of cuff pressure and complication in minimal closing capacity technology and pressure gauge measurement method to mechanical ventilation in severe patients. Methods The 118 patients which pressure gauge monitor cuff pressure 〉 30 cm H20 （ after the smallest dosed capacity aeration） were divided into two groups, and MOV and CPM were used for two groups. Results There were significant differences between the two groups to aeration time, actual pressure of Airbags, the rates of air leakage, the rate of aspiration. There were significant differences among the first time air sacs inflation pressure, the pressure of gas injection after 4houre and 8hour in respective group. Conclusions Minimal closing capacity technology can reduce the incidence rate of air leakage and complication.
