Retrospective study comparing success rates of lumbar puncture positions in infants

A lumbar puncture (LP) is performed in the emergency room for diagnostic purposes; unsuccessful or traumatic LPs can complicate decision making. The sitting position has a larger interspinous process compared to lateral recumbent and is safer in sick neonates at risk for cardiac and respiratory instability. Our study aims to determine which position (lateral recumbent or sitting) is associated with a greater likelihood of successful lumbar puncture in infants
