Summary

Placental insufficiency is responsible for fetal loss in about 40% of all stillbirths and long term neurological deficits. The mean interval from diagnosis of brain sparing of severe IUGR fetuses to delivery has been recently identified by only seven days (Flood K et al, Am J Obstetrics and Gynecology 2014).

The critical placental player in the active amino acids (AA) transport from the mother to the fetus is the trophoblast, which is irreversibly changed in severe IUGR fetuses caused by placental insufficiency. Thus, a logical partial solution of IUGR could be the direct supply of AAs and glucose to the fetus, in order to improve the fetal growth, normalize the fetal programming and to prolong the pregnancy.

The aim of this prospective pilot study is to further test the efficacy of the administration of AAs and glucose supplementation with hyperbaric oxygenation (HBO), via a subcutaneously implanted intraumbilical perinatal port system, as a treatment option for severe IUGR human fetuses with brain sparing.

Conditions

  • Intrauterine Growth Restriction

Interventions

DEVICE

fetal nutrition port system

Under local anesthesia a subcutaneous pouch for the port capsule was prepared using a pair of scissors. The umbilical vein was punctured with a 18 gauge needle under ultrasound control and the catheter was inserted into the umbilical vein. Note the amniotic cavity remained intact. A 25 gauge port needle was used to enter the port system. The treatment course included daily infusions of AA solution (Fresenius Kabi, Bad Homburg, Germany) with a 10% glucose solution. The investigators limited the volume of the intraumbilical infusion to 10% of the estimated feto-placental blood volume per day. On average, the AA/glucose-infusion was below 50 ml/kg.
