Abstract:
Objective To observe the effects of ritodrine hydrochloride,phloroglucinol and magnesium sulfate on serum sex hormones and fetal protection effect in patients with threatened abortion after 20 gestational weeks.Methods Patients with threatened abortion(after 20 gestational weeks)underwent fetal protection treatment were retrospectively enrolled.According to cohort method,they were divided into group A(ritodrine hydrochloride injection 100 mg+5％glucose injection 500 mL for intravenous drip,continued infusion after uterine contraction inhibition for 12-18 h,oral ritodrine hydrochloride tablets),group B(of phloroglucinol injection 40 mg+5％glucose injection 500 mL for intravenous drip,drug withdrawal after uterine contraction inhibition)and group C(magnesium sulfate injection 20 mL+5％glucose injection 100 mL,magnesium sulfate injection 40 mL+5％glucose injection 500 mL for intravenous drip after rapid intravenous drip,continued infusion after uterine contraction inhibition for 12 h).The onset time,disappearance time of uterine contraction,levels of serum sex hormones[progesterone(P),estradiol(E2),human chorionic gonadotrophin β-subunit(β-hCG)],adverse drug reactions and response rate of fetal protection in the three groups were observed.Results There were 40 cases in group A,38 cases in group B and 42 cases in group C.The onset time in group A,group B and group C were(1.71±0.34),(2.29±0.23)and(4.51±1.12)h,and the difference was statistically significant(P＜0.05).The disappearance time of uterine contraction in groups A,B and C were(1.34±0.32),(2.24±0.26)and(2.36±0.28)d,and the difference between group B and group A,between group C and group A were statistically significant(all P＜0.05).After 3 d of treatment,levels of serum P in group A,group B and group C were(78.64±10.34),(69.35±10.52)and(68.76±11.13)ng·mL-1;E2 levels were(672.25±85.63),(623.25±92.31)and(624.12±93.65)pg·mL-1;β-hCG levels were(6.95×104±1 258.65),(6.75×104±1 274.43)and(6.70×104±1 327.59)mU·mL-1;the difference between group B and group A,between group C and group A were statistically significant(all P＜0.05).The incidence rates of palpitation in groups A,B and C were 25.00％,0 and 9.52％,the difference between group A and group B was statistically significant(P＜0.05).The incidence rates of headache in groups A,B and C were 2.50％,2.63％and 26.19％;the difference between group A and group C,and between group B and group C was statistically significant(P＜0.05).The incidence rates of fatigue in groups A,B and C were 5.00％,0 and 19.05％,and the difference between group B and group C was statistically significant(P＜0.05).The incidence rates of gastrointestinal discomfort were 5.00％,0 and 11.90％,and the difference between group B and group C was statistically significant(all P＜0.05).The response rates of fetal protection in groups A,B and C were 92.50％,94.74％and 73.81％,and the difference between group A and group C,between group B and group C was statistically significant(all P＜0.05).Conclusion The onset time of ritodrine hydrochloride is short,which can be the first choice for disease control.Phloroglucinol is comparable to ritodrine hydrochloride in terms of fetal protection effect,which has better advantages in adverse drug reactions.Clinically,phloroglucinol can be considered for patients with poor tolerance to ritodrine hydrochloride.
