Abstract

Background: Nowadays in obstetrics, monitoring labor in women with premature amniotic rupture accompanied with sparse uterine contractions is not not suitable; using intravenous oxytocin infusion has been widely applied. Objectives: To analyze some factors related to oxytocin infusion results in pregnant women with premature rupture of membranes at Thai Nguyen A Hospital. Methods: A descriptive cross-sectional study on full-term pregnant women with early amniotic rupture of Stage Ia, who were assigned to receive oxytocin infusion at the Department of Obstetrics, Thai Nguyen A Hospital, from December 2020 to May 2021. Results: Through the study of 218 women, the average age was 27.7 ± 4.9 years old, the rate of amniotic rupture occurring within 6 hours accounted for 95.9%; the success rate was 79.8%, the failure rate was 20.2%, in which the cause of cervix not having progressed was 59.1%. The group of pregnant women with Bishop index > 6 points had a high success rate accounting for 94.4%; the success rate in the group of women giving birth from the second time was 92.6%, The group with birth weight ≤ 3500g had a high success rate, accounting for 83.2%. Conclusions: The Bishop index is related to the success rate, the higher the Bishop index, the higher the success rate and vice versa. In women giving birth from the second time, the success rate was higher than in women giving their first birth. Birth weight is associated with success rate: Success rates are inversely proportional to birth weight.
