Anaes SAQs · Paediatric anaesthesia
Physiological differences in the neonate relevant to anaesthesia
The Primary (basic-science) neonatal physiology SAQ — the reduced FRC + increased metabolic rate (rapid desaturation), the heart-rate-dependent cardiac output (bradycardia risk), the large surface-area-to-mass ratio (hypothermia), the immature renal/hepatic function (prolonged drug clearance), and the permeable blood-brain barrier.
