本文应用宫缩定量以及血镁浓度、产程时间、血压、产后出血量等指标,观察了9例产程开始后的妊高征患者静滴硫酸镁前后的自身宫缩变化情况.结果表明:在血镁达到妊高征治疗所需浓度的情况下,患者用药前后的宫缩张力、强度、持续时间、频率均无明显变化,且患者的产程亦正常,产后出血量也未增加.提示,对足月妊娠自然临产、产程正常的妊高征患者,产程中应用适量的硫酸镁是安全的。
In this paper, the contractions of uterine contractions before and after intravenous infusion of magnesium sulfate were observed in 9 patients with PIH after starting labor, and the contractions of uterine contractions and before and after magnesium sulfate injection were observed by using the indexes of uterine contractions, blood magnesium concentration, labor time, blood pressure and postpartum hemorrhage volume. Magnesium, pregnancy-induced hypertension to achieve the required concentration of the case, the patients before and after treatment of uterine contractions tension, intensity, duration, frequency had no significant change, and the patient’s birth process is normal, postpartum hemorrhage did not increase. Natural pregnancy-induced labor, normal labor process of pregnancy-induced hypertension syndrome, labor process application of magnesium sulfate is safe.
