不同院前急救方式对急性心肌梗死合并急性左心衰竭患者救治效果及预后的影响

Influence of Different Pre-hospital First Aid Methods on the Treatment and Prognosis of Acute Myocardial Infarction Complicated with Acute Left Heart Failure

目的探讨不同院前急救方式对急性心肌梗死合并急性左心衰竭患者救治效果及预后的影响。方法选取2017年5月至2019年3月在朝阳市第二医院接受急性心肌梗死合并急性左心衰竭治疗的72例患者,通过便利抽样法将入选的患者分为对照组和试验组,每组36例。对照组在转运过程中为患者实施简单处理后立即安排转运并于转运过程中为患者实施救治,试验组患者采用先救治后转运的急救方式,比较两组患者的救治效果及并发症发生情况。结果试验组治疗总有效率为91.67%,对照组治疗总有效率为77.78%,差异有统计学意义(P<0.05)。急救后,试验组患者呼吸频率、心率、舒张压及收缩压水平均低于对照组,差异有统计学意义(P<0.05)。试验组患者呼吸抑制发生率及病死率均低于对照组,差异有统计学意义(P<0.05);两组呼吸、心脏骤停发生率比较,差异无统计学意义(P>0.05)。结论为急性梗死合并急性左心衰竭患者提供先救治后转运的急救方式能够使救治有效率以及患者存活率得到明显提高。

Objective To investigate the eff ects of diff erent pre-hospital emergency methods on the treatment eff ect and prognosis of patients with acute myocardial infarction and acute left heart failure.Methods Select 72 patients who received acute myocardial infarction combined with acute left heart failure at Chaoyang Second Hospital from May 2017 to March 2019.The selected patients were divided into control group and experimental group by convenience sampling method,with 36 ca ses in each group.The control group performed simple treatment for the patients during the transfer process and immediately arranged the transfer and rescued the patients during the transfer process.The patients in the experimental group were treated with fi rst-aid treatment and then transferred.The treatment eff ect and complications of the two groups were compared.Results The total eff ective rate of treatment in the experimental group was 91.67%,and the total eff ective rate in the control group was 77.78%,the diff erence was statistically signifi cant(P<0.05).After fi rst aid,the respiratory rate,heart rate,diastolic blood pressure and systolic blood pressure of the test group were lower than those of the control group,and the diff erence was statistically signifi cant(P<0.05).The incidence of respiratory depression and mortality in the experimental group were lower than those in the control group,and the diff erence was statistically signifi cant(P<0.05).There was no signifi cant diff erence in the incidence of respiratory and cardiac arrest between the two groups(P>0.05).Conclusion The fi rst-aid method of providing fi rst-aid and post-transportation for patients with acute infarction and acute left heart failure can improve the effi ciency of treatment and the survival rate of patients.
