Maternal mean corpuscle volume and oxytocin augmentation during vaginal delivery.
OBJECTIVE
The aim of this study was to assess whether low maternal MCV values are associated with adverse course of vaginal delivery.


METHODS
A retrospective analysis of 92 consecutive vertex singleton vaginal deliveries in nulliparous women in a university tertiary health care facility. MCV was considered as major outcome variable.


RESULTS
54.1% of Parturients with higher MCV needed oxytocin augmentation during labor as compared to 79.5% of parturients with lower MCV (P<0.05). The need for oxytocin for augmentation of labor was decreased with larger MCV (OR 0.90 per fL, 95% CI 0.82-0.98, P<0.05). No correlation was found between MCV and other parameters of labor course.


CONCLUSIONS
Low maternal MCV values were associated with increased use of oxytocin augmentation during vaginal delivery.
