Evaluation of the Effectiveness of Obstetric Lubricant Gel in Labor in Nulliparous and Primiparous Women: A Randomized Controlled Study

The participants were divided into two groups based on their parity: nulliparous and primiparous. Initially, each group had 110 participants. Nulliparous and primiparous groups were randomly assigned to two groups as study and control groups using a computer-generated random number table. In this randomized controlled trial, participant allocation was carried out using a computer program to ensure a randomized and unbiased selection process. The randomization procedure was conducted in a double-blind manner, with the study investigators remaining unaware of the allocation until the conclusion of the study. All participants in the study received standard routine antepartum care in the delivery room. Among all patients, 25 participants were lost to follow-up during the study. Consequently, obstetric lubricant gel was applied to patients in the study groups, which included 47 nulliparous and 50 primiparous patients. Perinatal outcomes were compared between the groups

Inclusion criteria

• Nulliparous and primiparous singleton pregnancies between 37 and 41 weeks + six days of gestation and vertex presentation of fetus with an estimated birth weight of 2000 - 4500g were included in the study

Exclusion criteria
