title: Maternal and neonatal outcomes in vacuum-assisted delivery with the Kiwi OmniCup and Malmström metal cup.
abstract: OBJECTIVE
  To evaluate the effects of different types of vacuum cups on maternal and neonatal outcomes following assisted vaginal delivery.
  
  
  METHODS
  A retrospective cohort study was undertaken of all vacuum-assisted deliveries performed over a period of 2 years. Patients were divided into two groups according to whether a Kiwi OmniCup (n = 230) or Malmström metal cup (n = 98) was used. Maternal outcomes included maternal genital tract injury and total blood loss. Neonatal outcomes included Apgar score, umbilical cord blood gases, neonatal scalp injury and time spent in the neonatal unit.
  
  
  RESULTS
  Maternal or neonatal outcomes and failure rates did not differ between the two groups, however, the duration of the procedure and the fundal pressure maneuver was more frequent in the Malmström group.
  
  
  CONCLUSIONS
  The results of this study suggest that the Kiwi OmniCup and Malmström metal cup vacuum extractors are safe and functionally effective for vacuum-assisted delivery.
