Intrauterine PGF2 alpha infusion for termination of pregnancies with second-trimester rupture of membranes.

Intrauterine prostaglandin (PG) F2 alpha infusion and intravenous (IV) oxytocin infusion were compared to evaluate the effectiveness of the two methods for termination of pregnancies with second-trimester rupture of membranes. Twenty-two women with this complication were randomly allocated to receive either 20 mg PGF2 alpha, diluted in 500 mL of NaCl 0.9% and administered through a Foley catheter inserted through the cervix, or IV oxytocin infusion in increasing doses. All subjects in the PGF2 alpha group aborted after the first administration. Repeat infusion was necessary in three oxytocin-treated subjects. The mean (+/- SD) induction-abortion interval was significantly shorter in those receiving PGF2 alpha (6.7 +/- 1.2 hours) than in those receiving oxytocin (8.8 +/- 2.7 hours). Minor side effects, such as nausea and vomiting, were observed in three women during PGF2 alpha infusion and were treated symptomatically and by temporary interruption of the infusion. Uterine hypertonus, observed in one subject in each group, was treated by temporary cessation of the infusion. We conclude that intrauterine PGF2 alpha infusion seems more effective than IV oxytocin for termination of pregnancies with second-trimester rupture of membranes.

A scoring system for induction of labor using prostaglandin E2 vaginal tablets.

A randomized controlled trial was carried out in order to establish the efficacy of a scoring system for calculating the dose of vaginal prostaglandin E2 tablets for the induction of labor. One hundred ten women were included in the study. The patients received a dose of prostaglandin E2 calculated according to a scoring system based on the Bishop's score, or the standard dose of 3 mg repeated 6 h later if labor did not start. The percentage of inductions achieved was the same with both regimens (92.7%). The mean total dose used in the scoring system-group (2.7 mg) was significantly lower than that used in the 3-mg group (3.5 mg, P less than 0.025). Thirty-seven of 55 women receiving the scoring dose delivered with amounts of 2.5 mg prostaglandin E2 or less. Three cases of uterine hyperstimulation were observed in the 3-mg group whereas no cases were observed in the scoring group. The scoring system is proposed as a method for calculating the dose of vaginal prostaglandin E2 for induction of labor and minimizing the risk of overdosage.

Use of gas-forming agents in esophageal food impactions.

Twenty-six patients were treated with a gas-forming mixture of tartaric acid and sodium bicarbonate to relieve esophageal food impactions. A success rate of 65% was achieved, with one patient suffering a mucosal tear of the esophagus. Recommendations are made to limit the use of such gas-forming agents to impactions less than six hours old and in patients without chest pain.

The predictive value of fetal breathing movements in the outcome of premature labour.

Fetal breathing movements (FBM) were assessed in 28 pregnant women, presenting with uterine contractions before 34 weeks gestation. External tocometry was used to determine uterine contractions objectively. The first group consisted of 17 patients, treated by tocolytics after the ultrasound scanning showed absence of FBM. The second group comprised 11 patients with FBM present, who were observed only. In the first group nine women were delivered within 1 week, whereas in the second group no patient was delivered in that period, all of them being discharged. In patients with premature contractions the presence of FBM seems to indicate that the pregnancy will continue while absence of FBM foreshadows early delivery.

Electrocardiographic manifestations of dual pathways of retrograde impulse conduction in the human heart.

Three cases are presented in which the electrocardiogram provided evidence for the functioning of two separate pathways of retrograde impulse conduction. In the first case, distinct points of entry of the impulses into the atria are inferred. In the second case, the origin of the retrograde impulses was created by the stimuli of an artificial pacemaker. In the third case, the operation of two pathways of retrograde conduction was evidenced by the demonstrated differences of the refractory periods and the conduction velocities. Each of the three cases reflects a particular aspect of the phenomenon.
