Cardiovascular Transition of the Extremely Premature Infant and Challenges to Maintain Hemodynamic Stability

The Journal of Perinatal & Neonatal Nursing

Abstract

The intricate fetal circulatory blood flow undergoes abrupt changes and restructuring at birth, allowing transition to extrauterine life and survival. In the extremely low-birth-weight newborn infant (birth weight <1000 g), these changes are affected by the immaturity of the fetal cardiovascular and pulmonary systems. The immature physiology associated with the inability to transition properly can lead to a poor prognosis and create problematic issues for the clinical management of these infants. Potentially problematic issues and complications include immature myocardium, adrenal insufficiency, patent ductus arteriosus, hypotension, and anemia. Understanding the unique transition to extrauterine life for these infants, problems that arise from immaturity and incomplete transition, and current approaches to management will help nurses and physicians caring for ELBW infants to improve the care they give and minimize mortality and morbidity in this vulnerable population. This article will review transitional physiology for term and preterm newborns, potential problems and complications, and current management approaches.

Addison Disease

Addison's disease, also known as primary adrenal insufficiency and hypocortisolism, is a long-term endocrine disorder in which the adrenal glands do not produce enough steroid hormones. Discover the latest research on Addison's disease here.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Cardiovascular Homeostasis

Cardiovascular regulation and homeostasis is important in maintaining health and dysfunction may lead to cardiovascular diseases. Nitric oxide and vascular endothelium are one of many molecules involved in the homeostatic mechanism. Here is the latest research on cardiovascular homeostasis.

Brain Injury & Trauma

brain injury after impact to the head is due to both immediate mechanical effects and delayed responses of neural tissues.
