Intrauterine fetal growth restriction—the treatment modalities for clinical research, and the biochemical rationale

Abstract

Intrauterine Fetal Growth Restriction (IUGR) is a very important clinical problem for which no satisfactory treatment is available so far. The current invention of intravenous (IV) hypertonic glucose supplementation to the mother to improve the glucose transfer to the fetus at the intervillous space by improved facilitated diffusion can be a safe and easy way of treating this problem, as the improved fetal blood glucose can lead to fetal lipogenesis that can conserve the fetal O₂ (oxygen) utilization and also relieve the associated metabolic derangements of fetal hypoxia, hypercapnia, and acidosis, apart from replenishing the oxidized coenzymes needed for the carbohydrate metabolism. The use of trans-amniotic fetal feeding studied by animal experiments can be difficult in humans, because of the danger of infection, which can be overcome by the use of implantable ports with a sterile patch technique.

Description

INTRODUCTION[0001]This embodiment of invention is directed to novel treatments for ‘Intra Uterine Growth Restriction’ (IUGR) of a human fetus, one of a long known and incurable (but treatable) maternal-fetoplacental pathology resulting significant mortality and morbidity of the fetus / neonate, it's basic / clinical science research by investigators world wide so far being scant, and clearly disappointing, except for the herein disclosed treatment by the author inventor.[0002]Infants afflicted with intrauterine growth restriction (IUGR) of what ever etiology, or small-for-gestational age (SGA) infants are those whose birth weights are below the tenth percentile for their gestational age.[0003]The maternal diet is the main source of the nutrition supplied to the fetus. There are operational mechanisms in pregnancy to minimize glucose utilization by the mother, there by making it available to the fetus, as glucose is it's prime nutrient. One metabolic action of HPL (Human Placental Lactog...

Benefits of technology

[0021]3. Adequate glucose availability induces preferential carbohydrate catabolism in the fetus, thereby obviating beta oxidation of lipids, a high oxygen consuming path way.

[0022]4. Adequate glucose availability furthermore relieves fetal hypoxia (deficiency of oxygen reaching the tissues, to a leve

Problems solved by technology

As previously mentioned, the most common cause of intra uterine fetal growth restriction (IUGR) is vascular in nature resulting in the placental insufficiency, thus decreasing the transfer of D-Glucose, the most important fetal nutrient, across the placenta.

There are other adverse metabolic events like
