    Area of Science:

    • Obstetrics and Gynecology
    • Perinatal Medicine
    • Medical Device Technology

    Background:

    • The vacuum extractor is a medical device used in childbirth.
    • Its application and outcomes in diverse obstetric settings require continuous evaluation.
    • Understanding its utility in specific populations, such as those with smaller pelvic dimensions, is crucial.

    Purpose of the Study:

    • To evaluate the safety and efficacy of vacuum extractor use in a large cohort of deliveries.
    • To assess the instrument's performance in managing malpositioned fetal heads.
    • To determine the incidence of maternal and fetal complications associated with vacuum-assisted delivery.

    Main Methods:

    • Retrospective review of 1,526 delivery records from 1982-1983.
    • Data collected from the Hong Kong University Department of Obstetrics and Gynaecology.
    • Analysis of delivery outcomes, maternal/fetal injuries, and perinatal mortality.

    Main Results:

    • Vacuum extractor use was found to be easy and safe, even for inexperienced staff.
    • The device facilitated delivery of malpositioned fetal heads due to its autorotation capability.
    • Advantages included minimal space occupation, beneficial for smaller pelves; maternal injury was uncommon.
    • Fetal scalp injuries, like cephalhaematoma, were observed but serious injuries were infrequent.
    • The instrument-attributed perinatal mortality rate was low at 0.6 per 1,000 deliveries.

    Conclusions:

    • The vacuum extractor is a valuable tool in obstetrics, offering benefits for fetal malposition and smaller maternal pelves.
    • While generally safe, strict adherence to application protocols is essential for minimizing maternal and fetal risks.
    • The study highlights the need for careful technique to ensure optimal outcomes in vacuum-assisted deliveries.
