Meconium-stained amniotic fluid as a predictor of poor outcomes in gastroschisis.

OBJECTIVE

The aim of this study was to determine if meconium-stained amniotic fluid (MSAF) was associated with neonatal outcomes in gastroschisis.

STUDY

DESIGN

A retrospective chart review of gastroschisis patients from 2000 to 2014 at a single, tertiary institution was performed. Statistical analysis was performed with Fisher exact test, Welch's t-test, logistic regression and/or linear regression with significance at p < 0.05.

RESULTS

Sixty-four of 135 (47.4%) gastroschisis patients had MSAF. On univariate analysis, patients with MSAF were more likely to require staged closure (30 (46.9%) vs. 18(25.4%), p = 0.012), had more ventilator days (8.9 ± 11.1 vs. 5.3 ± 6.3, p = 0.021) and longer times to commence enteral feeds (24.9 ± 21.7 vs. 18.5 ± 14.5, p = 0.045). However, multi-variate regression analysis controlling for the type of closure, showed that delayed closure, but not MSAF, was associated with worse outcomes.

CONCLUSIONS

In gastroschisis patients, MSAF is associated with delayed closure but is not associated with outcomes independent of closure type. This association may be because of the matting of the bowel or increased intestinal damage. The MSAF status will aid in setting expectations for parents during their initial NICU stay and further investigation is warranted.
