摘要
目的探讨机械通气患者发生人机对抗原因和防治对策。方法对46例人机对抗患者进行回顾性分析。结果154例机械通气患者中发生人机对抗46例。其原因包括:气道阻塞14例,潮气量不足8例,急性肺水肿8例,严重感染、持续高热6例,支气管痉挛6例,气胸2例,多发伤疼痛1例,单肺通气1例。结论气道阻塞,潮气量不足,急性肺水肿等是人机对抗的主要因素,加强气道管理,设置合适的通气模式和(或)参数,解除气道痉挛,祛除诱因等综合治疗措施,可避免和减少人机对抗的产生。
Objective To discuss the reasons and strategy of cases with IPPV resisted to mechanical ventilation retrospectively. Methods To analysis 46 cases with IPPV resisted to mechanical ventilation. Results There were 46 cases resisted to mechanical ventilation among 154 cases with IPPV. The cause of resistance were multiple, including 12 cases with airway obstruction, 8 cases with insufficient tidal volume, 8 cases with acute pulmonary edema, 6 cases with persistant high fever, 6 cases with bronchial spasm, 2 cases with pneumothorax, lcases with send out more pain of injury, lcascs with single lung ventilation. Conclusion The causes of resistance are mainly airway obstruction, insufficient tidal volume acute pulmonary edema etc. It could be avoided and reduced through enhancing airway management and setting up adequate respiratory mechanical parameter and relieving bronchial spasm.
