Neonatal Assessment and Resuscitation

Question 1

Catecholamines have an important role in the following areas:

Answer 1

(1) the production and release of surfactant, (2) the transition to active sodium transport for absorption of lung fluid, (3) the mediation of preferential blood flow to vital organs during the period of stress that occurs during every delivery, and (4) thermoregulation of the neonate.

Question 2

Neonates raise their metabolic rate and release ________ in response to cold; this response facilitates the oxidation of brown fat, which contains numerous mitochondria. The oxidation results in __________ __________, the major mechanism for neonatal heat regulation.

Answer 2

norepinephrine, nonshivering thermogenesis

Question 3

For infants born at less than 28 weeks’ gestation, the use of ______ ______ or bags is recommended to minimize heat loss.25,26 The maintenance of a neutral thermal environment (i.e., 34° to 35° C) is recommended. However, in the neonate with a perinatal brain injury, mild hypothermia therapy through selective head or whole-body cooling is initiated in the first 6 hours of life and may be neuroprotective in the setting of hypoxia-ischemia.27

polythene wraps
