针刺人迎穴为主对原发性高血压降压效应观察

Observation of anti-hypertensive effect on primary hypertension treated with acupuncture at Ren-ying(ST 9) mainly

目的:观察针刺对高血压病血压的即刻作用及长期影响。方法:原发性高血压患者70例,于每日14:00—16:00针刺人迎、合谷、太冲、曲池、足三里,记录患者每日针刺前以及针刺5min、15min、30min的血压值,每周治疗5天休息2天,共治疗3个月。比较同一天内针刺各时点与针刺前血压,比较每隔15天针刺前与第1天的针刺前血压。结果:同一天针刺各时点收缩压较针刺前收缩压下降显著,差异具有统计学意义(均P<0.05),第1天、第15天、第30天及第60天各时点舒张压较针刺前下降,差异有统计学意义(均P<0.05);治疗3个月期间,每隔15天针刺前的收缩压及舒张压与第1天针刺前比较均下降明显(均P<0.05)。结论:针刺治疗原发性高血压既可降低即刻血压,又可维持降压效应,起到长期平稳降压的作用。

Objective To observe the immediate effect and the long-term effect on blood pressure （BP） in acu puncture for hypertension. Methods Seventy cases of primary hypertension were acupunctured at Renying （ST 9）, Hegu （LI 4）, Taichong （LR 3）, Quchi （LI 11） and Zusanli （ST 36） at 2：00-4：00pm. BP was recorded be- fore treatment and 5 rain, 15 minand 30 rain after acupuncture separately every day. The treatment was given for 5 days each week and stopped for 2 days. Totally, 3-month treatment was required. BP was compared at each time point with that before treatment separately on the same day, and made the comparison of it before the treatment every 15 days with that before acupuncture on the 1st day. Results On the same day, the systolic pressure at each time point after acupuncture was decreased as compared with that before acupuncture, indicating the statistically significant difference （all P（0.05）. The diastolic pressures at each time point on the 1st, 15th, 30th and 60th days of acupuncture were decreased as compared with that before acupuncture, indicating the statistically signifi cant difference （all P〈0.05）. In the 3-month treatment, the systolic pressure and diastolic pressure before treat- ment every 15 days were decreased as compared with that before the treatment on the 1st day （all P〈0.05）. Con- clusion Acupuncture can decrease the immediate BP and maintain the anti-hypertensive effect for primary hypertension so as to achieve the long-term stable anti-hypertensive effect.
