Comparing regional (spinal) versus general anesthesia effects on breathing after hip fracture surgery
Regional Versus General Anesthesia for Hip Fracture and Postoperative Oxygenation
This study will test whether spinal (regional) or general anesthesia leads to better oxygen levels in people over 65 having hip fracture surgery.

What this trial studies
This is a prospective observational study measuring oxygen saturation before and for about 24 hours after hip fracture surgery using a fingertip sensor and a monitoring bracelet, with no change to clinical care. Investigators will record comorbidities, medications, and perioperative data and will collect outcomes including postoperative pulmonary complications, sleep apnea indices, delirium, length of stay, and survival. The anesthesia approach (general vs spinal) will be compared with respect to oxygenation patterns and early postoperative respiratory outcomes. Data are collected at Santa Maria Hospital and affiliated wards in Lisbon, Portugal.
Who should consider this trial
Good fit: Ideal candidates are adults aged over 65 admitted for a proximal femur (hip) fracture who are scheduled for surgery and can consent or have a responsible person provide consent.
Not a fit: Patients who sustained their hip fracture during an existing hospitalization, those under 65, or those who decline monitoring are not eligible and will not benefit from this study.
Why it matters
Potential benefit: If successful, the results could help clinicians choose the anesthesia approach that reduces low oxygen events and respiratory complications after hip fracture surgery.
How similar studies have performed: Previous retrospective studies have reported conflicting results about anesthesia type and postoperative outcomes, so conclusive evidence is still lacking and prospective observational data are needed.
