目的:探讨多巴胺在中重度狭窄合并关闭不全型心脏瓣膜病术前应用的利弊。方法:34例中重度狭窄合并关闭不全型心脏瓣膜病患者,根据术前准备用药情况分为常规组和多巴胺组,观察2组的疗效。结果:多巴胺组患者多例右心房衰竭加重,2组对比差异有统计学意义(P<0.05)。结论:中重度狭窄合并关闭不全型心脏瓣膜病患者术前应慎用多巴胺,加强容量控制和血管扩张药物使用,以减轻前、后负荷为主。
Objective: To investigate the advantages and disadvantages of dopamine in the preoperative application of moderate and severe stenosis combined with valvular heart disease. Methods: Thirty-four patients with moderate or severe stenosis and valvular heart disease were divided into routine group and dopamine group according to preoperative medication. The curative effect of the two groups was observed. Results: In the dopamine group, many cases of right atrial failure worsened. The difference between the two groups was statistically significant (P <0.05). Conclusion: Patients with moderate-severe stenosis and incomplete heart valve disease should be carefully treated with dopamine before surgery to enhance the capacity control and use of vasodilators in order to reduce the pre-and post-load.
