augmentation of labor
Medical intervention to strengthen or accelerate inadequate uterine contractions during established labor using oxytocin or amniotomy.
Full Definition
Augmentation of labor involves medical interventions to enhance uterine contractility when spontaneous labor has begun but progress is inadequate. The primary method is intravenous oxytocin administration, titrated to achieve effective contractions typically every 2-3 minutes lasting 60-90 seconds. Amniotomy (artificial rupture of membranes) may also be used for augmentation by removing the cushioning effect of amniotic fluid. Indications include arrest disorders, weak contractions, or prolonged labor phases. Augmentation differs from labor induction in that contractions have already begun spontaneously. Continuous fetal monitoring is required due to risks of uterine hyperstimulation, which can compromise fetal oxygen delivery and increase uterine rupture risk.
Usage
Usage note: Distinguish from induction, which initiates labor; augmentation enhances already established labor.
