However, these positions can have significant impacts on the patient’s physiological functions. This article overviews the historical background of Trendelenburg position and reverse Trendelenbury position, their effects on various physiological functions, recent advancements in their clinical applications, and strategies for preventing and managing associated complications.展开更多
目的采用自身对照方法观察压力控制通气(PCV)时,Trendelenburg体位、人工气腹下与平卧位、非气腹相比呼吸力学指标随预设气道压变化情况。方法择期行腹腔镜直肠癌根治术患者30例,入室后常规心电监护,气管插管后以容量控制通气(VCV)作为...目的采用自身对照方法观察压力控制通气(PCV)时,Trendelenburg体位、人工气腹下与平卧位、非气腹相比呼吸力学指标随预设气道压变化情况。方法择期行腹腔镜直肠癌根治术患者30例,入室后常规心电监护,气管插管后以容量控制通气(VCV)作为基础通气方式,5 min后切换为PCV,以此时气道压为人工气腹前预设气道压,之后分别依次减少1 cm H_2O、恢复为预设值、增加1 cm H_2O;人工气腹15 min后气道压作为气腹后预设气道压,之后重复上述过程,每个时间点至少间隔5 min,记录各时间点平均动脉压(MAP)、心率(HR)、脉搏氧饱和度(SpO_2)、潮气量(VT)、动态肺顺应性(Cdyn),其中VT、Cdyn连续记录5个值取平均数,观察患者术后苏醒情况。结果人工气腹、Trendelenburg体位后,患者Cdyn、VT减小(P<0.01),MAP升高(P<0.05);预设气道压改变1 cm H_2O时,ΔVT减小(P<0.05),Cdyn变化差异无统计学意义。结论 PCV时,Trendelenburg体位、气腹状态下预设气道压每改变1个单位与平卧位、非气腹相比,VT改变明显减小而Cdyn改变无明显差异。展开更多
