Effect of transcutaneous electrical acupoint stimulation on the treatment of donation related vasovagal reaction / 中国输血杂志

ABSTRACT

【Objective】 To analyze the application value of transcutaneous electrical acupoint stimulation (TEAS) in treating blood donation-related vasovagal reaction (DRVR). 【Methods】 The donors, experienced DRVR in our No.1 and No.2 mobile blood donation trucks from January 2020 to November 2021, were selected as research subjects and divided into TEAS group and control group, according to different treatment methods.After the occurrence of DRVR, the control group adopted routine treatment methods, such as stoping phlebotomy immediately, laid flat on the back with the feet higher than the head, head tilted to one side, and loosing collar or tight clothes.In case of syncope, acupressure was given to Renzhong and Hegu, pulse and blood pressure were monitored, and blood donors were provided with proper amount of liquid after consciousness recovery.The TEAS group received extra TEAS treatment based on the above methods.According to the symptoms of DRVR, the two groups were sub-divided into non-syncope DRVR and syncope DRVR to observe the effect of different treatments. 【Results】 The total effective rate of TEAS in non-syncope DRVR(97.33%) and syncope DRVR group(97.06%) was higher than those of control group (vs 91.13% and 76.67%)(P<0.05). The changes of blood pressure and heart rate of blood donors before blood donation and after treatment with the two methods in the TEAS group were lower than those in the control group (systolic blood pressure change value 5.24±2.87 mmHg vs 7.42±3.44 mmHg, diastolic blood pressure change value 3.17±2.24 mmHg vs 3.67±2.51mmHg, heart rate change value 2.71±0.35 beats/min vs 3.46±0.49 beats/min), P<0.05. 【Conclusion】 TEAS has better effect than conventional treatments, especially for DRVR with syncope, and can quickly and effectively improve the syncope related symptoms and shorten the recovery time.Moreover, it is safe, non-invasive, simple economic and effective, which deserves application and popularization in mobile blood donation sites.
