MATERIAL AND METHODS: This was a double-blind, placebocontrolled trial conducted among women planned for emergent caesarean delivery for suspected foetal compromise where 100 were randomised to receive subcutaneous terbutaline or placebo. The primary outcomes were the neonatal acid-base status, while the 5- minute Apgar score, admission to the intensive care unit and the maternal outcomes were recorded as secondary outcomes.

RESULTS: Data from a total of 96 women were analysed and showed a lower incidence of neonatal acidemia (4.4% vs 10.4%) and fewer neonates born with umbilical artery pH of less than 7.20 (12.5% vs 27.1%) and 7.10 (4.2% vs 6.2%) after terbutaline injection. However, the difference in the incidence of neonatal acidaemia, mean cord pH and base excess, Apgar score or admission to the intensive care unit did not differ significantly. No difference was seen in the maternal mean arterial pressure, estimated blood loss or haematocrit after the surgery between the study groups. The only significant maternal effect was tachycardia which was more common after terbutaline injection (54.2% vs 25.0 %, p=0.003).

METHOD: A prospective cohort study of 31 consecutive newborn infants with UAC-associated aortic thrombi which were detected by abdominal ultrasonography after removal of UAC. Twenty-two infants were treated with intravenous infusion of low dose (1000 U/h) streptokinase, while nine others were not treated due to various contra-indications. Thrombolysis occurred after a mean interval of 2.2 days (standard deviation (SD) = 1.8) in the treated infants. In the untreated infants, spontaneous thrombolysis occurred significantly later, after a mean interval of 16.9 days (SD = 14.7) (95% confidence intervals of difference between mean intervals - 26.0, - 3.4; P = 0.02). Only one treated infant developed mild bleeding directly attributed to streptokinase therapy.
