Performance Of Kiwi Omnicup. Does Training Improve Outcome

The objective of this study was to evaluate the performance of Kiwi OmniCup to achieve vaginal delivery by trained clinicians. A prospective study of all ventouse deliveries by Kiwi OmniCup was undertaken between January and March 2006 at Northwick Park hospital, a large DGH in London. During this 3 month period, 1045 deliveries took place. OmniCup deliveries were attempted in 116 cases (11%). Successful vaginal delivery was achieved in 104 (90%) cases. This outcome was comparable to that reported in other studies of rigid cup vacuum delivery. 31% of successful deliveries had incorrect placement of the cup. Third and fourth degree perineal tears were reported in 10 cases (9.8%).One infant developed subdural haematoma requiring blood transfusion. Shoulder dystocia was encountered in 5 cases of which one developed Erb’s palsy. This study demonstrated that Kiwi OmniCup is an efficient device for assisted vaginal delivery and training in its correct use consistently improves outcome.
