title: The Release Trial: a randomised controlled trial of umbilical vein oxytocin versus placebo for the treatment of retained placenta.
abstract: OBJECTIVE
  Intraumbilical injection of oxytocin reduces the incidence of manual removal compared with placebo in the treatment of retained placenta. ENTRY CRITERIA: The women recruited will be stable haemodynamically, not bleeding vaginally, over 34 weeks of gestation and with a retained placenta for at least 30 minutes. TREATMENT ARMS: Oxytocin (50 IU) or sterile water (in identical vials) in 25 mL saline injected through an intraumbilical venous catheter.
  
  
  METHODS
  Five hundred seventy-two women.
  
  
  METHODS
  Need for manual removal of placenta. CENTRES: Initially, there will be two study sites in the UK (Liverpool and Sheffield) and five in Uganda (Mulago, Nsambia, Mengo, Rubaga and Arua).
