Abstract:
Twenty children who had been exposed to ritodrine in the management of preterm labor between 24 and 34 weeks' gestational age were examined at seven to nine years of life and compared with matched control subjects. No significant differences were detected in factors of growth, neurologic findings, and psychometric testing.Keywords:

Objective To investigate the effect of ritodrine hydrochloride(Anpo) for the prevention of premature labor.Methods A retrospective clinical study was undertaken for 42 ritodrine-treated and 40 magnesium sulfate-treated patients.The reactive time,gestational age at delivery,number of days gained in utero,infant birth weight and respiratory distress syndrome were observed.Results Compared with magnesium sulfate,there was a singificantly higher proportion of infants achieving 36 weeks′ gestation,birth weight,gestational age at delivery and the number of days gained in utero and a significantly reduced incidence of respiratory distress syndrome.The therapy and in-hospital days and side effects decreased.Conclusion Ritodrine has powerful and quick effect on inhibiting uterine contraction.It is safe and effective for the treatment of premature labor.

Fetal movements (FM) were measured using a real-time B-scan method in 50 women in the third trimester. One hundred ninety-five observations were made. The number of FM per 20-minute observation period was similar in normal, diabetic, and hypertensive pregnancies and in patients with placenta previa, but was significantly lower in patients with Rh isoimmunization and an affected fetus. The number of FM did not vary with gestational age, mode of delivery, or birth weight and was significantly increased in patients either with a reactive nonstress test (NST) or in the presence of fetal breathing movements (FBM). Fetal movements were absent before delivery in 4 patients: In 3, the fetus died in utero and in the other a positive contraction stress test (CST) was observed. Conversely, in 2 other fetuses who died in utero, FM were observed during the last examination before death. In both, the cause of fetal death was related to an acute change. No relationship between FM and neonatal death was observed. These data suggest FM monitoring may be helpful in evaluating antepartum fetal condition.

The literature on neurologic sequelae in infants with intrauterine growth retardation (IUGR) is reviewed. In many studies this term is used for only those infants who have a birthweight (BW) below the 10th percentile and are labeled small for gestational age (SGA). The etiology of IUGR can often be correlated with a characteristic pattern of in utero growth and a subsequently predictable pattern of postnatal growth and/or developmental outcome. The concept that certain premature infants who are appropriately grown for gestational age (AGA) but whose birth weights fall below the 50th percentile may have IUGR is supported by the analysis of data from this study. In attempting to predict the neurologic outcome, it may be more helpful to recognize etiologic factors such as sleep disturbances than to analyze infants by birth weight gestational age groups.

The perinatal mortality rate for twin gestation is in the range of 15 %, and this is due predominantly to prematurity, although twins may also be born growth retarded. Ritodrine HCl, a beta sympathomimetic drug, has been shown to be effective, both in stopping premature labor and in preventing intrauterine growth retardation. With this in mind, a double-blind study using ritodrine HCl or placebo was begun in order to study its effect on premature labor, intrauterine growth retardation, and the perinatal mortality rate in twins. Thus far, 30 patients have delivered and have been followed to 6 weeks postpartum. Although the results on individual patients have remained blinded to the investigators, an initial evaluation of the ritodrine and placebo groups have revealed no difference with respect to gestational age, birth weight, or perinatal mortality. These preliminary results are not significant. However, it appears that ritodrine HCl is a safe oral agent for the antepartum gravida and her fetus. The study will be continued until approximately 100 patients have been enrolled.

The article by Drs Matthews and Warshaw (Pediatrics 64:30, 1979) prompted us to analyze our data from an ongoing study of meconium staining, fetal outcome, and neonatal listeriosis. Our observations are given in the Table. We have excluded breech presentations from the fetal distress group as these are commonly associated with meconium passage even in the absence of fetal distress.1 Thus, contrary to their observations, 3.24% of babies <34 weeks gestational age passed meconium in utero.
