Comparative StudyCesarean delivery of the second twin after vaginal delivery of the first twin.
Cesarean birth of twin B after the vaginal delivery of twin A is an infrequent event. There is little information in the literature documenting outcome of vaginal-abdominal delivery. ⋯ Twenty-one cases of combined vaginal-cesarean section deliveries were managed at our institute in a 10-year period. There was no apparent increase in maternal and perinatal morbidity and mortality when twin B was delivered by cesarean section after vaginal delivery of twin A.

Electrocardiographic changes associated with ritodrine-induced maternal tachycardia and hypokalemia.
One hundred twelve patients in preterm labor were followed prospectively, with electrocardiograms taken before ritodrine therapy and at 6 and 24 hours of treatment. Ninety-six percent of patients developed sinus tachycardia. Other changes were seen in 79% of the study group. ⋯ A drop in potassium concentration was noted initially, but a direct correlation between potassium concentrations and frequency of electrocardiographic changes was not present. We conclude that the electrocardiographic changes that are often observed during myocardial ischemia may be frequent in asymptomatic patients treated with ritodrine and that these changes may be a physiologic expression of ritodrine-induced tachycardia or hypokalemia. The validity of the use of the presence of electrocardiographic changes as the only criterion for discontinuation of ritodrine therapy is questioned.

Atraumatic delivery in cases of malpresentation of the very low birth weight fetus at cesarean section: the splint technique.
A technique to assist in the atraumatic delivery of the very low birth weight fetus in cases of malpresentation at cesarean section is described; the technique minimizes potential trauma associated with version and/or extraction techniques. Use of uterine relaxing anesthetic agents and subsequent risk of hemorrhage are avoided.
