Audit of assisted vaginal deliveries at Aga Khan University Hospital: A retrospective study

Abstract

Background: Assisted vaginal birth is an alternative to cesarean delivery where indicated and canreduce both maternal and fetal morbidity and mortality. There is a need to maintain and improve skillsthrough training, research, and mentorship, especially in where access to cesarean delivery remains achallenge.Objective: To determine the incidence and outcome of instrumental deliveries at a university teachinghospital in Nairobi.Methods: A retrospective study was conducted at the Aga Khan University Hospital between Januaryand November 2015. All files of patients who had an instrumental delivery during this period wereextracted, and data were collected on parity, indication, type of instrument, birth weight, perineal status,and Apgar scores.Results: Of 3000 women who delivered during this period, 132 had assisted vaginal birth (4.4%).Nulliparous formed 66.7%, and indication was only given in 12% of the cases. 11 percent of all caseswere forceps, whereas 89% were via vacuum. Trainees performed 36 (27%), instructors performed 10(7.5%), and obstetricians 73 (55.5%) of all instrumental deliveries. Two-thirds of the forceps wereperformed by obstetricians. Most (68.9%) babies weighed between 3 and 4 kg. The perineum was intactin 6%, 51.5% had episiotomy, and 6% had a third-degree tear; however, a fourth-degree tear was notreported. Two procedures failed, and patients underwent emergency cesarean delivery. 116 (87.8%)babies had Apgar scores of >6 at 5 minutes.Conclusion: Assisted vaginal delivery remains a safe and vital skill in the labor ward and has its place inmodern obstetric practice. The rate shown here is much lower than that in most high-income countries.There is a need to improve training and documentation of indications.
