摘要:目的:分析多巴胺联合硝普钠持续静脉泵入治疗老年顽固性心衰的治疗效果及对心功能的影响。方法:将我院于2017年1月-2018年1月期间收治的老年顽固性心衰患者70例纳入本次研究,采取随机抽签的方式将其均分为两组,对照组35例采用常规治疗,治疗组35例在对照组的基础上采用巴胺联合硝普钠持续静脉泵入治疗,对两组患者临床疗效、心功能、不良反应发生情况进行对比。结果:治疗后,相比于对照组患者,治疗组患者治疗总有效率(94.3%VS77.1%)更高,左室射血分数、每搏指数、每搏输出量都更高,左室扩张末期、左室收缩末期内径都更低,且P<0.05,差异具有统计学意义;两组患者不良反应发生率对比(5.7%VS11.4%),P>0.05,差异无统计学意义。结论:多巴胺联合硝普钠持续静脉泵入治疗老年顽固性心衰疗效显著,能有效改善患者心功能,且不良反应少,安全性高。

Analysis of the clinical treatment of elderly patients with refractory heart failure

OBJECTIVE: To analyze the therapeutic effect of continuous intravenous infusion of dopamine combined with sodium nitroprusside on refractory heart failure and its effect on cardiac function. Methods: 70 patients with refractory heart failure admitted to our hospital from January 2017 to January 1818 were included in the study. They were divided into two groups by random lottery, and 35 patients in the control group were routine. In the treatment group, 35 patients in the treatment group were treated with continuous intravenous infusion of pamine and sodium nitroprusside on the basis of the control group. The clinical efficacy, cardiac function and adverse reactions of the two groups were compared. RESULTS: After treatment, the total effective rate (94.3% vs 77.1%) was higher in the treatment group than in the control group, and the left ventricular ejection fraction, stroke index, and stroke volume were higher. At the end of expansion and left ventricular end-systolic, the internal diameter was lower, and P<0.05, the difference was statistically significant. The incidence of adverse reactions in the two groups was compared (5.7% vs 11.4%), P>0.05, the difference was not statistically significant. Conclusion: Continuous intravenous infusion of dopamine combined with sodium nitroprusside is effective in the treatment of refractory heart failure in the elderly. It can effectively improve the heart function of patients with less adverse reactions and high safety.

心力衰竭是老年常见心血管疾病,顽固性心力衰竭经常规治疗、纠正病因诱因、吸氧治疗等均无显著效果,甚至加重。多巴胺与硝普钠均为顽固性心衰治疗常用药物,其中多巴胺属β1-受体兴奋剂,为非洋地黄类正性肌力药物;硝普钠为血管扩张剂,可增加心输出量[1]。但是有学者研究发现[2],硝普钠可释放硫氰酸或氰化物,长期应用、剂量过大等情况下可能引发中毒,因此,其临床应用具有较大争议。

1.资料与方法

1.1一般资料

将我院于2017年1月-2018年1月期间收治的70例老年顽固性心衰患者纳入本次研究,采取随机抽签的方式将其均分为治疗组和对照组,每组各35例。治疗组患者中男性21例,女性14例;年龄60~83岁,平均年龄(71.5±4.6)岁;病程1~11年,平均病程(5.4±1.1)年;对照组患者中男性19例,女性16例;年龄60~85岁,平均年龄(71.9±4.8)岁;病程1~10年,平均病程(5.2±1.0)年。

1.2方法

对照组患者采用常规治疗,嘱咐患者多休息,给予强心、利尿、吸氧等治疗,给予血管转换酶抑制剂和硝酸酯类药物治疗[3]。

治疗组患者在对照组的基础上采用多巴胺联合硝普钠持续静脉泵入治疗,将50mg硝普钠加入至50mL生理盐水或葡萄糖注射液中,将初始泵入量控制在5μg/min,密切监测患者血压等指标,并适时调整泵入量,若未见明显不良反应则可在30min后将药量增加2~4μg/min。将100mg多巴胺溶入至40mL生理盐水或葡萄糖注射液中,通过另一个微量泵持续泵入,将初始剂量控制为0.5μg/kg。密切监测患者血压情况,保证药物24h持续泵入。两组患者治疗周期均为1周。

2.结果

治疗后,相比于对照组患者,治疗组患者治疗总有效率更高,P<0.05,差异具有统计学意义。

3.讨论

硝普钠属血管扩张药,其起效迅速,扩张血管的效果较好,可舒张动脉和静脉血管,使心室负荷明显降低,还能通过加大静脉顺应性而降低心室充盈压,降低血管阻力并提升主动脉壁的顺应性,使得心排血量增加,明显改善心脏收缩功能,减轻患者各项临床症状。多巴胺是一类去甲肾上腺素的前体,其用药剂量直接关系到药效,小剂量的多巴胺对患者多巴胺受体及心脏β2受体具有较强的兴奋作用,能发挥出扩张冠状动脉、强心、增加尿量与肾血流量、降低循环阻力等功效。

由上可见,多巴胺联合硝普钠持续静脉泵入治疗老年顽固性心衰安全、有效,能明显改善患者心功能,值得推广应用。
