CELLULAR REACTIONS TO SUBEPENDYMAL PLATE HAEMORRHAGE IN THE HUMAN NEONATE

An evolutionary tradeoff: bipedalism requires a narrow pelvis, but larger brains require wider birth canals. Hence early birth. Chase Nelson analyzes a new theory in the debate over human neonate helplessness. Helplessness itself exerts a selective force; it requires intelligent parents.

Human Neonate

Teaching endotracheal intubation to a large number of house staff, nurses, and respiratory therapists is often a difficult task. The difficulty is mainly in finding appropriate situations for practice while at the same time not compromising patient care. The anesthetized kitten1 has been suggested as a good model for teaching intubation. Although practice on the kitten is useful, in my experience transference of the intubation skill to a clinical situation with a human neonate has been less than satisfactory.

Systems Physiology

Swallowing is a critical function for survival and development in human neonates, and requires cross-system coordination between neurologic, airway, and digestive motility systems. Development of pharyngo-esophageal motility is influenced by intra- and extra-uterine development, pregnancy complications, and neonatal comorbidities. Primary role of these motility reflex mechanisms is to maintain aerodigestive homeostasis under basal and adaptive biologic conditions including oral feeding, gastroesophageal reflux, and sleep. Failure may result in feeding difficulties, airway compromise, dysphagia, aspiration syndromes, and chronic eating difficulties requiring prolonged tube feeding. We review the integration of cross-systems physiology to describe the basis for physiologic and pathophysiologic neonatal aerodigestive functions.

The Mean ◽

Human Neonates

A few years after the iodine content of salt in Serbia was increased from 7 to 15 mg/kg NaCI, iodine, thyroxine (T4) and triiodothyronine (T3) concentrations were measured in thyroid tissue obtained at autopsy from 21 human neonates who died within 30 days after birth. The thyroidal iodine as well as T4 and T3 content per gland in?creased progressively with gestational age of human neonates (r = 0.73, 0.70 and 0.67 respectively, p < 0.001). In seven newborns (gestational age 36 to 41 weeks) the mean values for total iodine, T4 and T3 per gland were 109.1 ?g, 52.2 ?g and 4.4 ?g respectively. The results of iodine and iodothyroninc content found in neonatal thyroid gland, particularly at the end of gestation and a few days of postnatal life, indicates that the iodine supply was satisfactory.
