Comparison of Oxytocin Dosing Regimen' Low Versus High, in Gravida Women With BMI 30 and Above Undergoing Induction of Labor
Comparison of Oxytocin Dosing Regimen' Low Versus High, in Gravida Women With BMI 30 and Above Undergoing Induction of Labor
The goal of this clinical trial is to compare between higher and lower dose of oxytocin to induce delivery in obese women. Researches will compare between low and high doses of oxytocin. the study group will use high dose of oxytocin (20 units in 1000 ml) versus the control group which will use low dose of oxytocin (10 units of oxytocin in 1000 ml)
the duration and the progression of the first stage of labor is slower in obese women and oxytocin seems to be less effective in the treatment of protracted labor in obese women. There is no consensus in the literature about the optimal oxytocin dose. Hence, the objective of this study is to compare 2 oxytocin regimens, low VS high dose among obese women who need induction or augmentation of labor.
Women at term (37-42 weeks), requiring the use of oxytocin for induction of labor or for augmentation of labor. Who are obese (BMI 30 and above), Viable singleton pregnancies with Cephalic presentation. After their consent, will be randomization: in a 1:1 allocation.
Group 1 (control) will receive a low dose- 10 units of oxytocin in 1000 ml STD. Starting rate 12 ml/h increase dose by 12 ml/h every 30 min up to 5 contractions / 10 min. Max dose 120 ml/h.
Group 2 (study) will receive a high dose- 20 units of oxytocin in 1000 ml STD. Starting rate 12 ml/h increase dose by 12 ml/h every 30 min up to 5 contractions / 10 min. Max dose 120 ml/h.
The primary outcome of the study is the time from the start of oxytocin to delivery
Statistical analysis Mean time interval from initiation of augmentation/ induction with oxytocin until delivery was eight hours (±240 minutes), based on previous observation at the delivery ward. The aim of study is to demonstrate a difference of 2 hours between the 2 groups with an alpha of 0.05 and a power of 80%, a sample size of 64 women per group is required. The primary analysis will be performed on the groups as allocated, that is, by the intention to treat, including all women as randomized.
