Key result
Light sedation (BIS >80) during spinal anesthesia reduced 1-year mortality compared to deep sedation in patients with serious comorbidities (HR 0.43; 95% CI 0.19-0.97; P=0.04).

Hazard Ratio: 0.43 (95% CI 0.19–0.97)
Absolute Event Rate: 22.2% vs 43.6%
p-value: p=0.04
Light sedation during spinal anesthesia may improve 1-year survival in elderly patients with serious comorbidities undergoing hip fracture repair.
Brown et al. (2014) conducted an RCT in Hip fracture. Light sedation vs. Deep sedation (BIS approximately 50) was evaluated on 1-year mortality (in patients with Charlson score >4) (HR 0.43, 95% CI 0.19-0.97, p=0.04). Light sedation (BIS >80) during spinal anesthesia reduced 1-year mortality compared to deep sedation in patients with serious comorbidities (HR 0.43; 95% CI 0.19-0.97; P=0.04).
