足反射按摩预防妊娠高血压综合征的观察

Observation on the Prevention of PIH (Pregnancy Induced Hypertension) by Reflexology

目的,研究足部反射区按摩预防妊娠高血压综合征的疗效及其机理。方法:采用随机双盲法对49例孕妇(治疗组,其中治疗1组正常妊娠21例,治疗2组高危妊娠28例)自孕28周起,保证充分休息并连续进行足部反射区按摩至分娩;49例孕妇(对照组,其中对照1组正常妊娠26例,对照2组高危妊娠23例)自孕28周起,保证充分休息并连续口服小剂量降压药和利尿剂至分娩。结果:治疗组妊娠高血压综合征发生率为4.1％,显著低于对照组的18.4％;治疗2组较对照2组前列环素I_2的代谢物(6-keto-PGF_1a,)含量及其与血栓素A_2的代谢物(TXB_2)含量的比例(P/T)高,治疗1组较对照1组比值高。结论:足部反射区按摩能有效地预防妊娠高血压综合征的发生,其作用机理可能为促使前列环素I_2与血栓素A_2处于动态平衡状态有关。

Objective: To study the therapeutic effect and mechanism of the prevention of PIH with reflexotherapy.Method: A double-blind method was applied-selecting randomly 49 pregnant women as treatment group, out of them, 21 cases of normal pregnancy were defined as treatment group A,while 28 cases of critical pregnant cases as treatment group B. All pregnant women in treatment groups A and B were treated with reflexo-therapy starting from the 28th week of pregnancy till delivery. Another 49 pregnant women were also selected at random as control group. Among them,26 cases of normal pregnancy were defined as control group A, while the other 23 cases of critical pregnancy as control group B. For all cases in control groups A and B, reasonable dosage of hypotensor and diuretic were used starting from the 28th week of pregnancy till childbirth.Result: the occurrence rate of PIH in the treatment groups was 4. 1% , markedly lower than that of the control groups (18.4%). the amount of 6-keto-PGFlα(a metabolic product of prostacyclin I2) and its ratio to TXB2 (a metabolic product of thromboxane A2) P/T of the cases in treatment group B were higher than those of the cases in control group B. Similarly , those value of the cases in treatment group A were higher than those of the cases in control group A.Discussion: Reflexotherapy has shown effectiveness in preventing the occurrence of PIH. Its mechanism may arise from the maintanence of dynamic equilibrium between prostacyclin I2 and thromboxane A2 through the action of reflexology.
