Immediate effect of amniocentesis on fetal breathing and gross body movements.
The incidence of fetal breathing movements (FBMs) has been observed to be significantly reduced at 24 and 48 hours after amniocentesis. The cause is unknown. We studied the immediate effects of amniocentesis on two fetal variables, FBMs and gross body movements (FMs). No effect was observed in the incidence of FBMs but an immediate increase in FMs occurred.
