Score for Neonatal Acute Physiology-II (SNAP-II)
SNAP-II is a six-variable physiological scoring system designed to quantify acute illness severity in very low birth weight (VLBW) neonates and predict mortality risk. Developed by Richardson and colleagues in 2001 as a refinement of the original SNAP, it incorporates readily available bedside physiological variables (mean blood pressure, lowest body temperature, hypoxemia, seizures, urine output, and sepsis indicators) measured within the first 12 hours of life. SNAP-II is widely used in neonatal quality improvement, clinical research, and benchmarking of NICU outcomes.
