Umbilical arterial pH in patients with cerebral palsy.

Background: Umbilical arterial pH (UApH) in severe cerebral palsy (CP) is not fully understood.

Aims: This work aims to determine the relationship between fetal acidemia and clinical features of severe CP.

Study Design: A retrospective study design is used.

Long-term hypoxia alters endocrine and physiologic responses to umbilical cord occlusion in the ovine fetus.

Objective: This study was designed to determine the effect of umbilical cord occlusion (UCO) on fetal endocrine responses in the long-term hypoxemic (LTH) ovine fetus.

Methods: Pregnant ewes were maintained at high altitude (3820 m) from day 30 of gestation. Normoxic control and LTH fetuses were catheterized, and an inflatable occluder was placed on the umbilical cord at day 132 of gestation.

Long-term hypoxia alters ovine fetal endocrine and physiological responses to hypotension.

Exposure to long-term hypoxia (LTH) results in altered cortisol responses in the ovine fetus. The present study was designed to test the hypothesis that LTH alters adrenal responsiveness to fetal hypotension. Pregnant ewes were maintained at high altitude (3,820 meters) from day 30 of gestation.
