Sinusoidal fetal heart rate. II. Continuous tissue pH studies.
Two cases of SHR in labor monitored by continuous fetal tissue pH measurements are presented. Both showed onset of the pattern in the absence of fetal acidosis, a fall in TpH following the appearance of the abnormal FHR pattern, and fetal compensation with a good perinatal outcome. These patients demonstrate that the fetus may tolerate a SHR and recover from preacidosis and acidosis. Continuous pH measurement may be helpful in conservative management of patients with abnormal FHR patterns.
