Comparative StudyUmbilical artery flow velocity waveforms during spinal anesthesia.
The umbilical artery Doppler flow velocity waveform was recorded during spinal anaesthesia prior to elective caesarean section in 15 uncomplicated pregnancies. Although spinal anaesthesia was associated with a significant fall in maternal systolic and diastolic blood pressure, there was no change in the umbilical artery Pulsatility Index either after preloading the maternal circulation with 750-1000 ml of Hartman's solution or for the first 15 min after subarachnoid injection of 0.5% bupivacaine. ⋯ There was a weak negative correlation between fetal heart and the umbilical artery Pulsatility Index. These observations suggest that in normal pregnancy, spinal anaesthesia has no detrimental effect on the umbilical artery Pulsatility Index.

Comparative StudyInfluence of the mode of delivery on initiation of breast-feeding.
The initiation and the prevalence of breast-feeding after discharge from hospital was investigated in 370 singleton parturients and compared to the mode of delivery. Infants delivered by vacuum extraction or by caesarean section started suckling later, they were more often given formula prescription during the first 4 days, they were less often breast-fed during the night, and their mother's milk 'came in' later, but it did not affect the prevalence of breast-feeding after discharge. A sleepy infant, which was not very willing to suckle, was the most frequent nursing-problem mentioned by the mothers 4 days after delivery. Failure to start breast-feeding occurred in only 2.2% of the women, and after 6 months 52% were still breast-feeding their children.
