The influence of maternal age on pregnancy outcome in nulliparous women with twin gestation.

We sought to determine if outcomes of nulliparous twin pregnancies differ based on maternal age. Nulliparous women with current twin pregnancies were identified from a database of women enrolled for outpatient nursing surveillance. Data were stratified into four groups by maternal age: less than 20, 20 to 34, 35 to 39, and greater than or equal to 40 years. Maternal and neonatal outcomes for women less than 20, 35 to 39, and 40 or more were compared with 20- to 34-year-old controls using Kruskal-Wallis, Mann-Whitney, and Pearson chi-square analyses. We analyzed 2144 nulliparous twin pregnancies. Patients ≥35 years (34 to 39, 78.5% or ≥40, 85.9%) were more likely to have cesarean deliveries compared with controls 20 to 34 years old (71.2%). Women aged 35 to 39 were less likely to deliver at <37 weeks, and women in the ≥40 group were less likely to deliver at <35 weeks due to spontaneous preterm labor compared with the controls. Neonates born to women aged 35 to 39 had a greater gestational age at delivery and larger average birth weight than controls. Maternal and neonatal outcomes were not adversely influenced by advanced maternal age in nulliparous women carrying twin gestations.

An examination of the clinical benefits and cost-effectiveness of tocolytic replacement following recurrent preterm labor.

We examined pregnancy outcomes in women receiving nifedipine tocolysis having recurrent preterm labor (RPTL). Singleton gestations enrolled for outpatient nursing surveillance and prescribed nifedipine tocolysis were identified (N = 4748). Women hospitalized for RPTL at <35 weeks then resuming outpatient surveillance were included (N = 1366). Pregnancy outcomes of women resuming nifedipine (N = 830) were compared with those having an alteration in treatment to continuous subcutaneous terbutaline (N = 536). Overall, 56.7% (2692/4748) experienced RPTL. Half (50.7%) were stabilized and resumed outpatient surveillance with nifedipine or continuous subcutaneous terbutaline. Infants from women resuming nifedipine versus those with alteration of treatment to terbutaline were more likely to deliver at <35 weeks (28.0% versus 13.8%), weigh <2500 g (32.9% versus 20.3%), and require a stay in the neonatal intensive care unit (34.0% versus 23.1%), all P < 0.001. Alteration of tocolytic treatment following RPTL resulted in a decreased incidence of preterm birth and low birth weight, resulting in less admission to the neonatal intensive care unit and fewer nursery days.

Placenta percreta masquerading as an acute abdomen.

BACKGROUND: The incidence of placenta percreta has been on the rise during the past decades, coincident with the increase in cesarean deliveries. The diagnosis of this potentially life-threatening complication is difficult, especially when it masquerades as other severe complications of pregnancy. CASE: A woman with one previous cesarean delivery presented at 28 weeks of gestation with right upper quadrant pain. Laparotomy revealed an intraperitoneal hemorrhage from a protrusion of the placenta at the previous uterine incision remote from the site of pain presentation. The fetus was delivered, and a hysterectomy was performed with subsequent good recovery. Pathology confirmed placenta percreta. CONCLUSION: The presentation of an acute abdomen with symptoms remote from the site of pathology in the third trimester masked the diagnosis of placenta accreta. When a clear diagnosis cannot be established, operative exploration must be considered.
