Full Definition
del Nido cardioplegia is a specialized cardioplegia solution that provides extended myocardial protection with a single dose, typically lasting 60-90 minutes. Originally developed for pediatric cardiac surgery, it has gained widespread adoption in adult cardiac surgery due to its convenience and excellent myocardial protection. The solution contains lidocaine for membrane stabilization, mannitol for osmotic protection, and specific electrolyte concentrations to maintain cardiac arrest. This formulation eliminates the need for frequent redosing during longer procedures, improving surgical efficiency while maintaining optimal myocardial protection.
