咪唑安定在机械通气人机对抗中的疗效观察

The effect of Midazolam in human-machine confrontation of mechanical ventilation

目的:探讨在机械通气时,咪唑安定在人机对抗中的运用。方法:对29例在进行机械通气治疗过程中,由于自身因素造成人机对抗,使用咪唑安定的患者进行回顾性研究。结果:29例患者中发生人机对抗原因中不耐受插管刺激14例,中枢性呼吸频率(节律)改变6例,多发伤疼痛8例,频繁呃逆导致误触发1例。结论:人机对抗是机械通气过程中常见问题,其发生的主要原因有患者自身因素,呼吸机性能,使用者技术水平3方面;来自于患者自身的因素主要有对插管不耐受,疼痛等因素。咪唑安定能有效地缓解患者焦虑情绪,减少来自患者自身因素引起的人机对抗,保持人机协调。

Objective：To investigate the mechanical ventilation, midazolam in the use of man-machine confrontation.Methods：29 patients who occured man-machine confrontation that beacase of their own factors during the treatment of mechanical ventilation, patients who were used midazolam were studied retrospectively.Results：Occurred in 29 patients because of intolerance against the machine to stimulate the 14 cases of intubation, central respiratory frequency（rhythm） changes in 6 cases, 8 cases of multiple injury pain, frequent hiccups cause false triggering one case.Conclusion：Machine confrontation is a common problem of the process of mechanical ventilation.The main reasons for its occurrence are classified as patient＇s own factors, breathing machine performance, skill of the operator;Factors derived from a patient＇s own intolerance mainly on intubation intolerance, pain and other factors.Midazolam can effectively alleviate the anxiety of patients and reduce the factors from the patient＇s own man-machine fight, to keep human-machine coordination.
