The use of dilute infusion of pituitrin in obstetrics

Abstract

1.1. Dilute Pituitrin by the slow intravenous route was used in labor in 36 cases of uterine inertia.2.2. Thirty-four of the patients having either primary or secondary uterine inertia were primiparas.3.3. Twenty-five per cent of the primiparous patients with primary uterine inertia in labor failed to respond to stimulation with dilute Pituitrin infusion.4.4. One hundred per cent of the multiparous patients in labor with secondary uterine inertia responded successfully to stimulation with the Pituitrin infusion.5.5. The failure rate in the combined cases of primary and secondary uterine inertia was 11 per cent.6.6. Dilute Pituitrin by the intravenous drip was used for the induction of labor in 63 patients.7.7. Twenty-one per cent of these patients failed to respond to induction by this method.8.8. The success of induction by this method was determined by the condition of the cervix at the time of induction. A favorable cervix was followed by successful induction in 94.6 per cent of the cases with the intravenous drip of dilute Pituitrin. Induction in the presence of an unfavorable cervix was successful in only 57 per cent.9.9. Since there is more than a 50 per cent chance of success for induction with the use of dilute Pituitrin infusion, this method of induction is recommended for trial in all cases where a definite obstetrical indication exists.10.10. The use of dilute Pituitrin by the slow intravenous drip is recommended for the control of hemorrhage in the postpartum period.
