脉搏指示连续心排血量监测技术在重型颅脑损伤合并NPE患者救治中的应用

目的 探讨脉搏指示连续心排血量监测技术(PICCO)在重型颅脑损伤合并神经源性肺水肿(NPE)患者救治中的应用价值.方法 将该院重症医学科收治的52例重型颅脑损伤合并NPE患者分为观察组和对照组,每组各26例.对照组采取常规神经科治疗措施,通过中心静脉压(CVP)指导补液,观察组在对照组基础上通过PICCO监测血流动力学,根据心排血指数(CI)、血管外肺水指数(EVLWI)、肺血管通透性指数(PVPI)、全心舒张末期容积指数(GEDVI)、胸腔内血容量指数(ITBVI)等指导液体管理,比较两组临床治疗效果、血流动力学指标、颅内压(ICP)、平均每日输液量、机械通气时间、住院时间及格拉斯哥预后评分(GOS)评定.结果 观察组的心率(HR)、平均动脉压(MAP)、氧合指数(PaO2/FiO2)、ICP等指标改善较对照组更明显(P＜0.05);对照组CVP上升更明显(P＜0.05),观察组CI、EVLWI、PVPI、GEDVI、ITBVI等好转稳定;观察组的平均每日输液量、机械通气时间、住院时间均要少于对照组(P＜0.05);但两组预后良好率及病死率比较差异无统计学意义(P＞0.05).结论 PIC-CO可以更好地进行液体管理、改善临床症状、缩短上机及住院时间,但并未明显改善预后及降低病死率.

Application of pulse index continuous cardiac output monitoring technology in treating severe craniocerebral injury complicating neurogenic pulmonary edema patients

Objective To explore the application value of the pulse index continuous cardiac output monitoring technology (PICCO) in treating severe craniocerebral injury complicating neurogenic pulmonary edema(NPE).Methods Fifty-two cases of severe craniocerebral injury complicating NPE in the intensive care medicine department of this hospital were divided into the observation group and control group,26 cases in each group.The control group adopted the routine neurological treatment measures and guided the fluid infusion by monitoring the central venous pressure(CVP),while on the basis of the control group,the treatment group monitored the hemodynamics by PICCO and guided the fluid management according to the cardiac index(CI),extravascular lung water index (EVLWI),pulmonary vascular permeability index (PVPI),global end diastolic volume index(GEDVI) and intrathoracic blood volume index(ITBVI).The clinical curative effects,hemodynamic indexes,intracranial pressure(ICP),average daily infusion volume,mechanical ventilation time,hospital stay and GOS prognosis evaluation were compared between the two groups.Results The improvement of the heart rate(HR),mean arterial pressure (MAP),oxygenation index(PaO2/FiO2),ICP and other indicators in the observation group was more obvious than that in the control group(P＜0.05);the CVP rise in the control group was more obvious(P＜0.05);CI,EVLWI,PVPI,GEDVI and ITBVI in the observation group were improved and stabilized;the daily average infusion amount,mechanical ventilation time and hospital stay in the observation group were less than those in the control group(P＜0.05);but the good prognosis rate and mortality rate had no significant difference between the two groups(P＞0.05).Conclusion PICCO can better conduct the liquid management,improves the clinical symptoms,shortens the mechanical ventilation time and hospitalization stay,but the results show no significant improvement in prognosis and mortality.
