Impact of cardiac surgical timing on the neurodevelopmental outcomes of newborns with Complex congenital heart disease (CHD).

Background: More than half of infants with complex congenital heart disease (CHD) will have a neurodevelopmental disorder of multifactorial causes. The preoperative period represents a time-window during which neonates with complex CHD are in a state of hypoxia and hemodynamic instability, which fosters the emergence of brain injuries and, thus, affects early brain networks and neurodevelopmental outcomes. Currently, there is no consensus regarding the optimal age for cardiac surgery in terms of neurodevelopmental outcomes, and its definition is a real challenge.

Brain tissue penetration of ciprofloxacin following a single intravenous dose.

Ciprofloxacin distribution was assessed in cerebral tissues in 14 patients undergoing craniotomy. The study objective was to determine the brain tissue/serum concentration ratio of ciprofloxacin. Patients received a single intravenous (iv) 200 mg dose of ciprofloxacin.
