propranolol and Fetal Hypoxia

propranolol has been researched along with Fetal Hypoxia in 12 studies

Propranolol: A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.
propranolol : A propanolamine that is propan-2-ol substituted by a propan-2-ylamino group at position 1 and a naphthalen-1-yloxy group at position 3.

Fetal Hypoxia: Deficient oxygenation of FETAL BLOOD.

Trial Outcomes

Median Apgar Score at 5 Minutes

The Apgar score is a simple method of quickly assessing the health and vital signs of a newborn baby created by and named after Dr. Virginia Apgar. Apgar testing assesses Appearance, Pulse, Grimace and Activity in a newborn and is typically done at one and five minutes after a baby is born, and it may be repeated at 10, 15, and 20 minutes if the score is low. The five criteria are each scored as 0, 1, or 2 (two being the best), and the total score is calculated by then adding the five values obtained. Agar scores of 0-3 are critically low, 4-6 are below normal, and indicate that the baby likely requires medical intervention, scores of 7+ are considered normal. The lower the Apgar score, the more alert the medical team should be to the possibility of the baby requiring intervention. Some components of the Apgar score are subjective, and there are cases in which a baby requires urgent medical treatment despite having a high Apgar score. (NCT01131260)
