The Study of Giving Birth, a Study About Treatment of Labor Dystocia
Labor dystocia is an intransigent, high-profile issue in obstetric care, which causes
 significant maternal morbidity in low resource settings and maternal dissatisfaction, and
 increased healthcare costs worldwide. Amniotic fluid lactate, (AFL), values have recently
 been shown to reflect the metabolic status of the uterus and high levels have a strong
 association with subsequent need for operative intervention due to dystocia. In sports
 medicine, it is known that lactic acid can affect muscular performance but be decreased by
 bicarbonate given orally before physical activity. Main Outcome Measures: If an intake of
 bicarbonate, one hour before stimulation with oxytocin in cases with a high AFL value,
 changes the AFL levels and enhances delivery outcome in dystocic deliveries.

 Design: Randomized controlled trial
Primary question: whether high AFL values (>12mmol/l) in women with observed dystocic labor
 are best treated by

 1. to handle childbirth according to the clinic's current guidelines in case of labor
 dystocia, i.e. with oxytocin stimulation

 2. an intake of bicarbonate (Samarin) dissolved in water given 1 hour before the oxytocin
 is started Primary outcome variable A comparison of the frequency of spontaneous vaginal
 delivery in the observed two described intervention groups.
