Abstract

Objectives: For very preterm births, to compare alternatives policies for umbilical cord clamping and immediate neonatal care.

Design: Parallel group randomised (1:1) trial, using sealed opaque numbered envelopes.

Setting: Eight UK tertiary maternity units.

Participants: 261 women expected to have a livebirth before 32 weeks, and their 276 babies.

Interventions: Cord clamping after at least two minutes and immediate neonatal care with cord intact, or clamping within 20 seconds and immediate neonatal care after clamping.

Main outcome measures: Intraventricular haemorrhage (IVH), death before discharge.

Results: 132 women (137 babies) were allocated clamping ≥2 minutes and neonatal care cord intact, and 129 (139) clamping ≤20 and neonatal care after clamping; 6 mother infant dyads were excluded (2, 4) as birth was after 35+6 weeks, 1 withdrew (death data only available) (0, 1). Median gestation was 28.9 weeks for those allocated clamping ≥2 minutes, and 29.2 for those allocated clamping ≤20 seconds. Median time to clamping was 120 and 11 seconds respectively. 7 of 135 infants (5.2%) allocated clamping ≥2 minutes died and 15 of 135 (11.1%) allocated clamping ≤20 seconds; risk difference (RD) -5.9% (95% confidence interval -12.4% to 0.6%). Of livebirths, 43 of 134 (32%) had IVH versus 47 of 132 (36%) respectively; RD -3.5% (-14.9% to 7.8%). There were no clear differences in other outcomes for infants or mothers.

Conclusions: This is promising evidence that clamping after at least 2 minutes and immediate neonatal care with cord intact at very preterm birth may improve outcome; a large trial is urgently needed.
