Effect of amnioinfusion on the outcome of prenatally diagnosed gastroschisis

fusion could improve the outcome of gastroschisis affected fetuses. The hypothesis by which this improvement could be due to a reduction of an inflammatory response remains to be proved. Objective: Following recent data showing that an inflammatory response exists in the amniotic fluid of gastroschisis-affected fetuses, we hypothesized that amniotic fluid exchange or amnioinfusion would improve the prognosis of prenatally diagnosed gastroschisis. Methods: We compared the outcome of prenatally amnioinfused fetuses with gastroschisis to non-amnioinfused fetuses with gastroschisis. 10 patients undergoing this procedure were matched with 10 patients of our previous study. Comparisons were done on data including surgical procedure, follow-up in the NICU and the gastropediatric unit. Results: Our results show that gastroschisis-affected fetuses undergoing amnioinfusion had a lower duration of curarization after surgery (2.2 +/- 1.9 vs. 6.8 +/- 6.9 days, p = 0.019), a shorter delay before full oral feeding (49.7 +/- 21.5 vs. 72.3 +/- 56.6 days, NS), and a shorter overall length of hospitalization (59.5 +/- 19.7 vs. 88.5 +/- 73.6 days, NS). We confirmed our previous data showing that amniotic fluid displays a chronic inflammation profile. Conclusion: Our data suggest that amnioinfusion could improve the outcome of gastroschisis affected fetuses. The hypothesis by which this improvement could be due to a reduction of an inflammatory response remains to be proved.
