The research was conducted to compare the length of the second stage of labor in twin and singleton gestations and evaluate the length of the second stage of labor in twin births.
The retrospective cohort study was from three major Israeli hospitals. Clinical information was gathered from the electronic medical record. The length of the second stage was the major consequence. The connection of clinical variables with the length of the second stage was investigated using multivariable linear regression. The duration of the second stage was studied in twin and singleton pregnancies.
There were 2,009 twin deliveries and 135,217 singleton deliveries between 2011 and June 2020. Of the twin deliveries, 655 (32.6%) of the patients were nulliparous (95th percentile length of the second stage 3 hours and 51 minutes), 1,235 (61.5%) were parous (95th percentile 1 hour 56 minutes), and 119 (5.9%) were grand multiparous (five or more prior deliveries) (95th percentile 1 hour 24 minutes). Epidural usage was related to a statistically significant increase in the length of the second stage of 40 minutes in nulliparous patients and 15 minutes in parous individuals in women having twins. The length of the second stage was greater in patients delivering twins compared to singletons in all groups. In twins, second-stage length greater than the 95th percentile was related to newborn intensive care unit hospitalization and the requirement for phototherapy.
Twins had a lengthier second stage of labor than singletons, and it is connected with obstetric history. Normal ranges for the second stage might help guide clinical treatment.
