title: Skin blood flow in normal pregnancy measured by venous occlusion plethysmography of the hand.
abstract: Total hand blood flow was measured by venous occlusion plethysmography in 14 healthy primigravid women. Consecutive measurements were made from the 15th week of pregnancy until term and after delivery. During pregnancy the mean hand blood flow, measured under standard resting conditions with the subjects supine, increased progressively from 7.7 in early pregnancy to 28.9 ml/100 ml/min at term. Simultaneously the peripheral vascular resistance decreased from 19.3 to 3.3 PRU100. When examined at 6--16 weeks after delivery hand blood flow and peripheral resistance were not yet returned to normal.
