Abstract

Objective: Vacuum-assisted delivery is the most preferred operative vaginal delivery method and Kiwi Omnicup is a recently designed system for vacuum-assisted delivery with has a plastic cup, flexible traction wire, and a handheld vacuum pump. The aim of this study was to assess the Kiwi Omnicup application rates in a tertiary care hospital and evaluate the early neonatal and maternal outcomes of Kiwi-assisted deliveries.

Methods: The Kiwi Omnicup Vacuum-assisted deliveries after 37 weeks of gestation between January 2016 and December 2019 at a tertiary care hospital were reviewed in this study. The sociodemographic characteristics of the patients, obstetric data, early postpartum neonatal, and maternal outcomes of the patients were obtained. The vacuum-assisted delivery indications, including the prolonged second stage of labor, maternal exhaustion, and fetal compromise were recorded. Maternal and neonatal complications including, third or fourth-degree perineal lacerations, early postpartum hemorrhagic, shoulder dystocia, fetal death, fetal scalp laceration, and neonatal intensive care unit necessity of newborns were recorded.

Results: During the study period, 58 (1.28%) of the 4525 vaginal deliveries were performed with the Kiwi Omnicup system. The mean age of the patients was 25.3±5.3 years. The mean body mass index of the patients was 28.4±3.2 kg/m2 and 86.2% of the patients were overweight and obese. The prolonged second stage of labor was the most recorded (48.3%) indication for Kiwi-assisted delivery. Caput succedaneum occurred in 5 neonates (8.6%). Eight newborn babies were observed closely in the Pediatric department. Two newborns were transferred to the intensive care unit. Any other maternal and neonatal complications were observed.

Conclusion: The Kiwi Omnicup Vacuum system is easy to use and has low maternal and neonatal adverse outcomes. Although the feasibility of this system was confirmed by several studies, it has low usage rates. The reasons for avoidance from Kiwi omnicup vacuum usage at delivery should be evaluated.
