This project was designed to explore the effects of ritodrine hydrochloride combined with magnesium sulfate in the prevention of preterm delivery of patients with threatened premature birth. 128 cases of threatened premature birth were randomly divided into two groups according to the number table method. The control group was treated with magnesium sulfate, while the study group was treated with ritodrine hydrochloride combined with magnesium sulfate. The data (p > 0.05) was analyzed using SPSS 18.0 and was subjected to Chi-square and t-test. The onset time and prolonged gestation time of the study group were shorter than those of the control group (p < 0.05). There was no difference in the incidence of myocardial ischemia between the study group and the control group (p > 0.05). The heart rate per minute of the study group was higher than that of the control group (p < 0.05). There was no difference in blood pressure between the study group and the control group. Nevertheless, the neurological function, pregnancy outcome, and neonatal status of the group were better than those of the control group (p < 0.05).
