Perinatal pharmacology and cerebral blood flow

Abstract

Many of the drugs used in neonatal intensive care units might impede cerebral blood flow, thereby increasing the risk of intraventricular hemorrhage and periventricular leukomalacia. Our studies focussed on sick preterm neonates who were treated with the following drugs: caffeine (20 mg/kg i.v., as caffeine citrate); phenobarbital (loading dose: 20 mg/kg); indomethacin (0.2 mg/kg/dose, every 12 h three doses), and synthetic surfactant (Exosurf; 50 mg/kg = 5 ml/kg intratracheally). All of the drugs studied, except indomethacin, had no adverse effect on cerebral hemodynamics.
