34.  PLACENTAL WEIGHT IN RELATION TO NVP 

1.   Positive correlation for increased nausea was found with heavier placental weight (P=0.005). 363 women in study. (53)

2.   The placental weight of subjects who had morning sickness was higher than those who had none. (P

3.   No obvious correlations between emesis gravidarum and placental weight were found. 
(NVP n=62, no NVP n=28). (19)

4.   NVP not associated with placental weight. 873 women in the study, 69% had NVP. (44)

5.   There was no difference in placental weight between patients with vomiting and patients with no vomiting. 1,453 formed the study population. 63% vomited, 12% did not vomit. (63)

PLACENTAL PATHOLOGY IN RELATION TO NVP

No statistical difference between women with hyperemesis gravidarum (n=164) and controls (n=209) in terms of placental pathology. (64)

Pathologic reviews of placentas from women receiving total parenternal nutrition with fat emulsions during the study period showed no gross abnormality.
Nine women with hyperemesis gravidarum. (73)
