Predicting postoperative hypotensive events after posterior spinal fusion for adolescent idiopathic scoliosis.

The 4-h monitoring protocol identified 25% of HEs, suggesting limited predictive capacity. the protocol demonstrated a sensitivity of 25%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 88%.

Hypotensive events remain difficult to predict, illustrating the importance of frequent blood pressure monitoring postoperatively and quick hypotensive response capabilities.
