摘　　要：目的探究不同时段肌肉收缩和舒张活动(AMT)预防献血者血管迷走神经反应(VVR)的作用与价值。方法选取2020年5月~2022年5月易发VVR人群共计2992例,随机(抽签式)分为对照组(1406例)和观察组(1586例),对照组未给予AMT干预,观察组献血过程中进行不同时段AMT干预,监测2组各时段收缩压、舒张压及心率指标变化情况及献血者焦虑(SAS)心理状态,对比各时段VVR发生情况。结果2组献血前血压、心率指标差异无统计学意义(P>0.05),献血中、献血后观察组各项指标相对稳定,与对照组差异显著,P<0.05;SAS评分献血前差异不显著,P>0.05,献血中及献血后观察组较对照组低,P<0.05;观察组VVR发生率为3.09%,低于对照组的7.97%,差异有统计学意义(P<0.05)。各时段进行肌肉收缩和舒张活动,其中献血中AMT练习后,VVR发生率2.18%。结论针对献血人群给予不同时段AMT干预,献血中进行AMT干预,降低VVR的发生效果明显。Objective To explore the role and value of applied muscle tension(AMT)in preventing vasovagal nerve reaction(VVR)in blood donors.Methods A total of 2992 people,susceptible to suffer VVR from May 2020 to may 2022,were randomly divided into control group(1406 cases)and observation group(1586 cases).The control group was not given AMT intervention,while the observation group received AMT intervention at different periods during blood donation.The changes of systolic blood pressure,diastolic blood pressure,heart rate and psychological state of anxiety(self-rating anxiety scale,SAS)of blood donors were monitored in the two groups at each period to compare the occurrence of VVR.Results There were no statistically significant differences in blood pressure and heart rate between the two groups before blood donation(P>0.05).The parameters were relatively stable in observation group during and after donation,but significantly different from that of the controls(P>0.05).SAS score was similar in two groups before blood donation(P>0.05),while decreased in observation group during and after donation in comparison with the controls(P<0.05).The incidence of VVR in the observation group was 3.09%,which was significantly lower than that in the control group(7.97%)(P<0.05).The incidence of VVR was 2.18%after AMT exercise during blood donation.Conclusion AMT intervention in different periods of blood donation can significantly reduce the occurrence of VVR.
