Background Intrauterine growth restriction (IUGR) is one of the most prevalent causes of fetal mortality and fetal morbidity, affecting up to 10% of all births and it is associated with increased risk of neurological, cardiovascular and metabolic diseases later in life. Even though numerous studies intended to find a therapy for IUGR, no standard therapy for IUGR has been established so far. Objective To examine the effect of an intrauterine nutritional therapy in the IUGR rabbit model in terms of survival and birth weight. Methods IUGR was surgically induced in pregnant rabbits (n=16) at gestational age 25 by ligating 40–50%of uteroplacental vessels of each gestational sac in both uterine horns. At the same moment, fetal injections of Total Parenteral Nutrition solution (TPN) was administered into the amniotic sac of IUGR fetuses (n=90) in one horn, whereas sham injection was performed in the contralateral horn (n=86). Five days after, a cesarean section was performed obtaining treated and non‐treated IUGR animals. Results Survival rate of treated IUGR animals were significantly higher than the non‐treated IUGR animals (61.5% and 41.9% respectively, p=0.013). Birth weight were similar between groups (38.4 g ± 9.3 SD vs. 36.2 g ± 8.5 SD, p=0.49, treated vs. non‐treated IUGR respectively,). Conclusion Our data suggests that TPN solution directly administrated to the IUGR animals at the time of IUGR induction could increases the survival rate, with no difference in birth weight. Further studies are needed in order to confirm the results and try to fully evaluate the potential benefits of such strategy in promoting fetal survival.
