目的观察拉贝洛尔联合硫酸镁治疗重度子痫前期的临床效果。方法将重度子痫前期患者94例采用随机数字表法分为联合组和硫酸镁组,各47例。硫酸镁组给予硫酸镁治疗,联合组给予拉贝洛尔联合硫酸镁治疗。比较2组临床疗效、并发症发生率及治疗前后患者血压、24 h尿蛋白水平。结果联合组总有效率为95.74%显著高于硫酸镁组的78.72%,差异有统计学意义(P<0.05);联合组并发症发生率低于硫酸镁组(P<0.05);治疗前2组血压、24 h尿蛋白水平比较差异无统计学意义(P>0.05),治疗7 d后2组血压、24 h尿蛋白水平均降低,且联合组改善更显著(P<0.05)。结论拉贝洛尔联合硫酸镁治疗重度子痫前期的临床效果确切,可有效降低患者血压水平,减少24 h尿蛋白水平,降低产后出血、新生儿窒息、子痫等并发症发生率,有利于改善妊娠结局,值得临床推广应用。
Objective To observe the clinical effect of labetalol combined with magnesium sulfate in the treatment of severe preeclampsia. Methods Ninety-four patients with severe preeclampsia were randomly divided into the combined group and the magnesium sulfate group, 47 cases in each group. Magnesium sulfate group given magnesium sulfate treatment, the combination group received labetalol combined with magnesium sulfate treatment. The clinical curative effect, the incidence of complications and the blood pressure of patients before and after treatment were compared between the two groups. The 24 h urinary protein levels were compared. Results The total effective rate in the combined group was 95.74%, which was significantly higher than that in the magnesium sulfate group (78.72%, P <0.05). The complication rate in the combined group was lower than that in the magnesium sulfate group (P <0.05) There was no significant difference in blood pressure and 24 h urinary protein levels between the two groups (P> 0.05). After 7 days of treatment, the blood pressure and 24 h urinary protein levels were decreased in both groups, and the combination group improved more significantly (P <0.05). Conclusion The combination of labetalol and magnesium sulfate in the treatment of severe preeclampsia has definite clinical effect, which can effectively reduce the blood pressure level, reduce the level of 24 h urine protein, reduce the incidence of complications such as postpartum hemorrhage, neonatal asphyxia and eclampsia Improve pregnancy outcomes, it is worth clinical application.
