Abstract:Objective To explore the effect of Magnesium Sulfate,Nifedipine plus Labetalol in treating pregnancy-induced hypertension (PIH) patients.Methods A total of 87 PIH patients treated from January to October 2019 in our hospital were selected.According to random number table,patients were divided into reference group (n=43) and research group (n=44).The reference group took Magnesium Sulfate and Nifedipine; the research group took Magnesium Sulfate,Nifedipine combined with Labetalol.Clinical efficacy,hemodynamics and urine protein changes for two groups were compared.Results The total clinical effective rate in the research group (93.18%) was higher than that in the reference group (81.40%),with statistical difference (P<0.05); after treatment,blood viscosity and erythrocyte ratio in the research group were lower than those in the reference group,with statistical differences (P<0.05); after treatment,24 h urine protein,mucoprotein and human urinary kallidinogenase levels in the research group were lower than those in the reference group,with statistical differences (P<0.05).Conclusion Magnesium Sulfate,Nifedipine combined with Labetalol can remarkably reduce the blood viscosity and erythrocyte ratio,improve 24 h urine protein quantitation and increase therapeutic effects.
