Amnioexchange for fetuses with gastroschisis: is it effective?

Area of Science:

• Perinatal medicine
• Fetal surgery
• Neonatal care

Background:

• Amniotic fluid in fetuses with gastroschisis (GS) contains inflammatory mediators and waste products.
• Diluting or removing these substances is proposed to protect the herniated intestine.

Purpose of the Study:

• To evaluate the effectiveness of serial amnioexchange procedures in fetuses with GS.
• To assess changes in amniotic fluid composition and clinical outcomes.

Main Methods:

• Serial amnioexchange performed bimonthly during the third trimester.
• Analysis of amniotic fluid for biochemical and inflammatory markers.
• Correlation of markers with gestational age, treatment course, and clinical outcomes.

Main Results:

• No correlation found between amniotic fluid markers and gestational age.
• No trends observed in marker values during amnioexchange treatment.
• No association between markers and clinical outcomes like time to enteral feeding.

Conclusions:

• Serial amnioexchanges did not change amniotic fluid's biochemical or inflammatory status.
• The procedure did not appear to prevent injury to the herniated gut.
• Use of serial amnioexchanges in GS is not recommended outside of prospective trials due to potential risks.
