Introduction: Neonatal period is characterized by transition to extra uterine life and rapid growth and development. Newborn period, just first 28 days of life, carries the greatest risk of mortality. Despite being less than 2% of total period of under 5 children, the newborn period accounts for over half of under 5 child mortality. Good care therefore not only improves survival of children but lays foundation of optimal log term physical and neurocogitive development. Aim: The aim of the study is to assess the effectiveness of simulation on neonatal BLS( basic life support) among selected colleges of nursing in Greater Noida , UP. The findings of the study can help the teacher to gain knowledge regarding the effectiveness of simulation on neonatal BLS( basic life support). Methodology: Intervention: Simulation of Neonatal BLS( basic life support). Types of studies: True Experimental study. Types of participants: Nursing students Setting: Selected colleges of Greater Noida, UP. Results: This narrative review result has proved that simulation of neonatal BLS( basic life support) has increased in terms of knowledge and skills among nursing students.
