1.Study on the tocolysis effectiveness of nifedipin on uterine contraction in the management of preterm labor
Journal of Medical Research 2005;36(3):44-52
A clinical trial was performed to evaluate the tocolytic possibility of nifedipin and to propose a treatment regimen for preterm labor in the National Hospital of Gynecol-Obstet from July 2003 to December 2003. There were 40 cases of preterm labor with gestational age 31 weeks and 3 uterine contractions per minute on average. Patients received a 10 mg sublingual loading dose every 20 minutes (maximum dose 40mg), and followed by 20 mg oral dose every 6- 8 hours. Result: the effectiveness in tocolysis of nifedipin is very fast. It took 60-80 minutes to arrest uterine contraction (70- 80%) (including contractions of high frequency and intensity), especially in urgent tocolysis. The lower the frequency and intensity is, the higher and sooner the effectiveness is. 92.5% of delivery were delayed for 48 hours. 82.85% were postponed until 36 weeks, and the mean time of prolonged pregnacy was 39 days. Side-effects were mild and transient and in normotensive pregnant women blood pressure was almost unaffected. This treatment regimen of nifedipin showed the effectiveness in preterm labor. In brief, nifedipin is an effective, safe, convenient and economic tocolytic agent. It may well represent the best suitable tocolytic alternative currently available and can be used widely in Viet Nam.

Preterm birth accounts to 35 % of deaths in a year. Twin gestation, around 7.2 per 1000 births in the Philippines, is a known risk factor that increases likelihood of preterm birth compared to singletons. Most studies that addresses preterm births are focused on singleton pregnancies. There have been no established recommendations to control preterm labor in twin pregnancies. Pessary insertion is among these recommendations. There are no reported cases of pessary insertion to control preterm birth among twins in the Philippines. This study presents a case of twin gestation in preterm labor and no functional cervix on transvaginal ultrasound. Hodge pessary was inserted at 28 weeks age of gestation. She delivered at 36 weeks to live baby girls, both 2,200 grams and were directly roomed-in. Further studies are recommended to establish stronger evidence supporting pessary use in multiple gestation to improve outcome of neonates.

Ritodrine hydrochloride (Yutopar) is commonly used for the treatment of preterm labor. Published reports claim that many complications of prematurity have been averted by the administration of this drug. However, ritodrine hydrochloride has many side effects, including cardiovascular problem and metabolic error. Only a few reports have described the transient hepatitis (elevated transaminase) all over the world. The clinical significance and incidence of this side effect are still unclear. In this report, we present a case of elevated serum transaminase levels associated with the use of ritodrine during pregnancy with a brief review of the literatures.
