A safe method of amniocentesis for lecithin/sphingomyelin determination in late pregnancy using ultrasound.

Two hundred consecutive amniocenteses for lecithin/sphingomyelin (L/S) determination in late pregnancy are reviewed. These procedures were performed under ultrasonic control before induction of labor or elective cesarean section in a prospective study to determine a safe method for aminocentesis. Complications included 3 failures, 14 blood-stained samples, 2 cases of labor occuring within 24 hours after amniocentesis, and 1 maternal abdominal wall hematoma. There was no cases of perinatal morbidity or mortality. It is proposed that this is a safe method of abdominal amniocentesis for L/S determination in late pregnancy.

Venous and volume factors in women during and after normotensive pregnancy.

1. Venous compliance and plasma volume were measured in thirty-one continuously normotensive women early (11-20 weeks) and late (31-40 weeks) in pregnancy and following delivery. 2. Mathematically fitted pressure/volume curves, obtained by venous occlusion plethysmography, were analysed according to two describing functions (i) the peak of the first derivative dv/dp max and (ii) a work index, integral of 25 (10) p dv. 3. The relationship between venous/volume factors seen after delivery, was disturbed during pregnancy, at which time the work index provided evidence for decreased venous compliance. 4. Pregnancy could be regarded as a potentially hypertensive state, brought about by a vascular/volume mismatch.
