[Five questions about the Kiwi OmniCup vacuum extractor].

The vacuum extractor Kiwi OmniCup (Clinical Innovations, Muray, Utah, USA) has been developed to provide several advantages. This is a complete system with an integral hand-held vacuum operated by the obstetrician. This is also a single use instrument, which may reduce the risk of potential transmission of infections and the logistic of sterilization process. Further potential benefits of this system include the smaller overall equipment size and the ability to measure traction force. However, the data about its efficiency remain conflicting. The first works demonstrated very high successful rate of vaginal delivery, whereas two recent randomized studies showed that the Kiwi Omnicup was less efficient than currently used vacuum extractor. It appears to be as safe as conventional a device for both mother and newborn. However, further additional data remain necessary needed to complete its evaluation.
