Fetal heart rate response to intrauterine saline solution flush.
Response of the fetal heart rate to instillation of normal saline solution 5 ml through an intrauterine pressure catheter was observed on 50 occasions. The test was performed only in those patients in whom an intrauterine pressure catheter had been placed. When the fetal capillary pH was greater than 7.24, accelerations of fetal heart rate by 15 beats/min were observed in 39 of 50 occasions. On the other hand, no fetal heart rate accelerations were observed when the fetal capillary was less than or equal to 7.24.
