急性左心衰竭患者不同院前急救模式的疗效观察

Efficacy observation of different pre-hospital first-aid modes on patients with acute left heart failure

目的研究不同院前急救模式应用于急性左心衰竭患者的临床疗效。方法选取2019年1~12月30例急性左心衰竭患者为参照组,另选取2020年1~12月30例急性左心衰竭患者为试验组。参照组采取边急救边转运的院前急救模式,试验组采取先急救再转运的院前急救模式。对比两组治疗效果,到达现场时、上车时、到达医院时的血氧饱和度、心率变化情况,开始救治时间、院前救治时间、住院时间。结果试验组总有效率90.00%高于参照组的60.00%,差异具有统计学意义(P<0.05)。试验组上车时、到达医院时的血氧饱和度(0.83±0.07)、(0.93±0.02)高于参照组的(0.78±0.09)、(0.86±0.06),心率(123.30±8.01)、(110.21±5.63)次/min低于参照组的(130.21±3.62)、(121.30±6.59)次/min,差异具有统计学意义(P<0.05)。试验组开始救治时间、院前救治时间、住院时间分别为(86.93±10.21)min、(91.24±9.63)min、(10.21±3.21)d,均短于参照组的(201.36±11.20)min、(210.28±21.36)min、(14.02±4.12)d,差异具有统计学意义(P<0.05)。结论对急性左心衰竭患者给予先急救再转运的院前急救模式,可确保治疗效果,促使患者生命体征逐渐趋于稳定,促进患者预后恢复,对急性左心衰竭患者具有重要意义,值得借鉴。

Objective To study the clinical efficacy of different pre-hospital first-aid modes on patients with acute left heart failure.Methods 30 patients with acute left heart failure from January to December 2019 were selected as the reference group,and another 30 patients with acute left heart failure from January to December 2020 were selected as the experimental group.The reference group received pre-hospital first-aid mode of transferring while giving first aid,and the experimental group received pre-hospital first-aid mode of giving first aid and then transferring.Both groups were compared in terms of therapeutic effect,changes of blood oxygen saturation and heart rate when arriving at the scene,getting on the bus and reaching the hospital,initial treatment time,pre-hospital treatment time and the hospitalization time.Results The total effective rate of 90.00%in the experimental group was higher than that of 60.00%in the reference group,and the difference was statistically significant(P<0.05).When getting on the bus and reaching the hospital,the blood oxygen saturation of the experimental group were(0.83±0.07)and(0.93±0.02),which were higher than those of(0.78±0.09)and(0.86±0.06)of the control group;the heart rate of the experimental group were(123.30±8.01)and(110.21±5.63)beats/min,which were lower than those of(130.21±3.62)and(121.30±6.59)beats/min of the reference group;the differences were statistically significant(P<0.05).The initial treatment time,pre-hospital treatment time and the hospitalization time of the experimental group were(86.93±10.21)min,(91.24±9.63)min and(10.21±3.21)d,which were shorter than those of(201.36±11.20)min,(210.28±21.36)min and(14.02±4.12)d of the reference group,and the differences were statistically significant(P<0.05).Conclusion The pre-hospital first-aid mode of giving first aid and then transferring for patients with acute left heart failure can ensure the therapeutic effect,promote the gradual stabilization of patients'vital signs and promote the recovery of patients'prognosis.It is of great significance for patients with acute left heart failure and is worthy of reference.
