Intrauterine fetal growth restriction (IUGR) is an affliction of a disparaging spectrum, placental insufficiency being the major inciting pathology. The resultant fetal hypoglycemia is alleviated by intravenous hypertonic D-glucose 25-50% maternal supplements, by improving the Vmax of placental transfer for D-glucose, in accordance with Michaelis-Menten model of substrate transfer. Fetal normoglycemia so restored in turn surprisingly improves fetal hypoxia, hypercapnia, hyperlacticemia, acidosis, hypertriglyceridemia, oliguria / hydromnios, and the fetal nutrient / mineral / vitamin acquisition. The list being phenomenal can only convince an inquiring reader by a biochemical sojourn into the aquatic world of the fetus, herein described. Maternal carbohydrate-predominant IUGR diet with maximal amounts of vitamin / mineral supplements are highly beneficial. Transamniotic isotonic D-glucose supplements via minimally invasive suprapubic extraperitonial pelvic approach and amniotomy (Sumathi Paturu's technique), with a subcutaneously implanted pregnancy port (SIPP) catheter is the additional therapy advocated.
