【摘要】 目的:探讨中心静脉压测定在急性右心室心梗中的应用价值。方法:按照随机数字表法,将102例急性右室心梗并低血压休克患者分为A组(n=33)、B组(n=36)、C组(n=33)。三组患者均给予相同的基础治疗和扩容治疗,A组、B组、C组的CVP分别维持在6~12 cm H2O、13~19 cm H2O、20~26 cm H2O,比较三组患者的心率(HR)、平均动脉压(MAP)、尿量(UV)、心输出量(CO)以及肺水肿发生率。结果:A组和B组的肺水肿发生率均明显低于C组(P<0.05);B组和C组患者入院治疗12、24 h的HR均显著慢于A组,MAP、UV、CO值均显著高于A组(P<0.05);单纯右室心梗患者的CVP值明显高于非单纯右室心梗患者(P<0.05)。结论:中心静脉压测定在急性右室心梗扩容治疗中具有重大意义,其最佳维持范围应在13~19 cm H2O。

【Abstract】 Objective:To explore the application value of central venous pressure in acute right ventricular myocardial infarction.Method:According to the random number table method,102 patients with acute right ventricular myocardial infarction(AMI) were divided into A group(n=33),B group(n=36),C group(n=33).Three groups were given the same basic treatment and volume expansion therapy,A group,B group,C group of CVP were maintained at 6-12 cm H2O,13-19 cm H2O,

20-26 cm H2O,the heart rate(HR),mean arterial pressure(MAP),urine output(UV),cardiac output(CO) and incidence of pulmonary edema of the three groups were compared.Result:The incidence of pulmonary edema in A group and B group were significantly lower than that in C group(P<0.05);admission to hospital for treatment of 12 h and 24 h,the HR of B group and C group were significantly slower than that in C group,UV,CO,MAP were significantly higher than those in A group(P<0.05);CVP values in patients with simple right ventricular myocardial infarction was significantly higher than that of patients with non simple right ventricular infarction(P<0.05).Conclusion:Central venous pressure measurement has great significance in the treatment of acute right ventricular myocardial infarction,and its optimal maintenance range should be between 13-19 cm H2O.

急性右室心肌梗死患者往往伴随低血压与休克症状,其病理、生理和血流动力学改变情况和左室心肌梗死的差异决定了其治疗方法也不同于左室心肌梗死。目前扩容治疗是临床上应用得较为普遍的一种治疗措施,需在有创血流动力学监测的前提下开展。作为血容量变化的重要指标,中心静脉压(CVP)给急性右室心肌梗死的扩容治疗提供了有效的指导作用[1-2]。然而急性右室心肌梗死扩容到底应该补充多少液体,中心静脉压应该维持在什么范围之内比较好,是很多学者比较关心和经常讨论的话题。本研究通过急性右室心肌梗死的临床观察旨在探讨进行扩容治疗时需保持的中心静脉压理想范围,现将结果报道如下。

1 资料与方法

1.1 一般资料

将2012年1月-2015年1月笔者所在医院收治的102例确诊为急性右室心肌梗死并低血压休克的患者作为研究对象,均进行颈内静脉置管。按照随机数字表法,分为三组(A组、B组、C组)。……
