Abstract
OBJECTIVE
To discuss the effect of the Kiwi OmniCup system on reducing adverse maternal and neonatal outcomes and provide a reference for assisted vaginal delivery methods.
METHODS
Women who gave birth to singleton term neonates in a cephalic presentation and underwent assisted vaginal delivery from 2017 to 2021 were eligible for inclusion in the study; they were divided into a Kiwi OmniCup system group and a forceps group. Binary logistic regression analysis was used to observe and compare maternal and neonatal outcomes. The primary outcomes were severe maternal and neonatal morbidity. Severe maternal morbidity was defined as the occurrence of at least one of the following outcomes: third- or fourth-degree perineal lacerations, refractory postpartum hemorrhage, thrombotic events, amniotic fluid embolism, admission to the intensive care unit, and maternal death. Severe neonatal morbidity was defined as the occurrence of at least one of the following outcomes: neonatal asphyxia requiring resuscitation or intubation, neonatal head and face injuries, neonatal fracture, and admission to the neonatal intensive care unit for longer than 24 h.
RESULTS
The rate of severe neonatal morbidity in the forceps group was significantly higher than that in the Kiwi OmniCup system group, the differences between the two groups were significant (27.2% vs. 42.3%, P < 0.001), and there was no significant difference in the rate of severe maternal morbidity between the two groups (30% vs. 30%, P > 0.05). Binary logistic regression analysis showed that Kiwi OmniCup system-assisted delivery reduced severe neonatal morbidity (adjusted odds ratio 0.49; 95% confidence interval 0.33-0.73) and did not increase severe maternal morbidity compared with forceps-assisted delivery.
CONCLUSION
The Kiwi OmniCup system, which can reduce the incidence of severe neonatal morbidity without increasing the incidence of serious adverse maternal outcomes, is worthy of clinical promotion.
