Effect of amniotic fluid volume on neonatal outcome in diamniotic twin pregnancies.
OBJECTIVE
We assessed neonatal outcome of normal diamniotic twin pregnancies with known amniotic fluid (AF) volume.


METHODS
The AF volume was empirically determined in 39 diamniotic twin gestations. The neonates were stratified by AF volume and evaluated for clinical outcome, gestational age, lecithin-sphingomyelin (L/S) ratio, and birth weight.


RESULTS
Neonatal complications did not significantly differ among infants delivered from pregnancies with low (155 to 404 mL), moderate (405 to 807 mL), or high (808 to 5,430 mL) volumes of AF. Relatively constant volumes of AF were maintained throughout the 27 to 38 week range of gestational age, with no apparent correlation between AF volume and gestational age. Variations in the L/S ratio and newborn birth weights were also independent of AF volume. Gestational age was the only significant determinant of the frequency of neonatal complications.


CONCLUSIONS
Amniotic fluid volume does not greatly affect neonatal outcome in normal diamniotic twin pregnancies.
