DEF

A contraction stress test in which uterine contractions are stimulated by intravenous infusion of oxytocin.

DEF

Épreuve qui permet, grâce à une injection d'ocytocine, d'obtenir un certain nombre de contractions utérines et d'étudier leur effet sur le rythme cardiaque fœtal, afin de déterminer l'état du fœtus et de détecter s'il est en souffrance.

CONT

Le test à l'ocytocine peut étudier la tolérance du fœtus aux contractions. Si le RCF [rythme cardique fœtal] reste normal malgré 2 heures de contractions utérines induites fréquentes et bien ressenties, ce test dit négatif témoigne d'un excellent bien-être fœtal pour une semaine.

OBS

épreuve à l'ocytocine; EO : terme, abréviation et définition recommandés et en instance de normalisation par l'OLF.
