Beyond incidence: clarifying the evidence-based predictors of failed spinal anesthesia

Key Points

• Failed spinal anesthesia occurs due to specific predictors that affect success rates and patient outcomes.
• Key predictors include anatomical variations and patient health indicators, which influence the incidence of failure.
• Observational analysis reveals significant correlations between patient characteristics and outcomes of spinal anesthesia.
• Findings may enable improved anesthetic practices and patient selection, calling for external validation in broader settings.
