Blood pressure in the fetal guinea-pig.
Mean arterial blood pressure and heart rate in guinea-pig fetuses during late gestation have been recorded in situ under maternal pentobarbitone anesthesia. The measurements were performed via a catheter in one of the umbilical arteries. Mean arterial umbilical pressure and heart rate were 28 +/- 5 mmHg and 282 +/- 30 beats/min, respectively. It is suggested that the recorded pressure is consistent with the rise in systemic arterial pressure in other species during gestation and postnatal life.
