Immunoglobulin therapy offers several benefits: - Enhanced Immune Response: Provides immediate antibodies to fight infections. - Reduction in Mortality and Morbidity: Especially in critical conditions like neonatal sepsis. - Decreased Need for Other Interventions: Such as exchange transfusions in HDN. - Support for Immune-Compromised Neonates: Provides essential immune support until the neonate’s immune system can function independently.
