Atenolol: side effects in a newborn infant

As long as the cervix is unfavourable, oxytocin is of doubtful value and the high dosages required may lead to water intoxication. Therefore, systemic or local administration of prostaglandins is preferred. We have obtained excellent results with intravenous infusion of prostaglandin E,,1 and others have reported successes with intracervical instillation of a single dose of 0 5 mg prostaglandin E, suspended in viscous gel.2 Intravaginal prostaglandin F2e (2-5 mg) gel shortens labour considerably without increasing fetal distress or hypertonicity.3 Once the membranes have ruptured, however, insertion of a catheter into the extra-amniotic space is technically impossible (A Calder, personal communication), and the results obtained with oral prostaglandin E2 are contradictory.4 One new technique that might reduce the risk of infection deserves mention-that is, continuous intravaginal infusion (lavage) of a weak solution of polyvinylpyrrolidone and iodine (Iso-Betadine). This method was originally proposed by Saling,6 and preliminary results are encouraging.
