Foetal plasma magnesium levels during maternal hypo- or hypermagnesaemia in ewes.

1. The influence of maternal hypo- or hypermagnesaemia of foetal plasma magnesium levels was studied in pregnant ewes between the 120th and the 145th day of gestation using a permanent catheter inserted in utero into the left aorta of the foetus on the 115th day of gestation. 2. In seven ewes, carrying eleven foetuses, the injection of 1 alpha-hydroxycholecalciferol induced a hypomagnesaemia wh...

Bupivacaine 0.125% in epidural block analgesia during childbirth: maternal and foetal plasma concentrations.

The maternal plasma concentration of bupivacaine has been determined in 19 patients receiving a continuous epidural block during labour, using bupivacaine 0.125% with adrenaline 1:400,000. The plasma concentration of bupivacaine rarely exceeded 0.18 /*g/ml. Bupivacaine does not accumulate in the maternal blood when such low concentrations are used. The plasma concentration of bupivacaine has al...

In order to compare the hormonal environment during the treatment to that during pregnancy, the concentrations of total estrogens (TE), progesterone (P4), glucocorticoids (G) and prolactin (Prl) in the...

Maternal and foetal heart rates during exercise in horses

This study tested two hypotheses. First, that moderate exercise would alter maternal and foetal heart rate (HR) in the horse. Second, that pregnancy would alter the HR, plasma cortisol and plasma lactate response to moderate exercise in mares. Six unfit, pregnant Standardbred mares (6–19 years) underwent two incremental graded exercise tests (GXT). The first GXT was performed at approximately 9...

Maternal foetal iron relationship.

The relationship between maternal and foetal iron nutrition has evoked considerable interest and debate. In pregnancy the demand for iron is increased by the mother’s need to expand her red cell mass to fulfill the requirements of the developing foetus. Foetal hon is derived solely from the mother through the active transport function of the placenta, and the quantity transferred might reasonab...
