What this Trial Is About
Researchers are comparing two types of anesthesia, general and spinal, for hip fracture surgery in older adults aged 65 and above. The study aims to measure oxygen levels before and after surgery and investigate how each anesthesia method affects sleep apnea, delirium, respiratory complications, and hospital stay length. This observational study does not change the usual care or treatments but collects important data to better understand postoperative outcomes in this population. The study observes patients undergoing hip fracture surgery with either general or regional anesthesia. Oxygen saturation is monitored at the fingertip using sensors and bracelets during the operation and for about 24 hours afterward. The research team gathers information on respiratory complications, delirium, sleep apnea, length of stay in the post-anesthesia care unit and hospital, and survival without any intervention or discomfort to participants. Participants will have data collected in the operating room and hospital wards primarily within the first day after surgery. Health information and existing medical conditions will be recorded, but the study measurements will not affect medical care. The primary outcome is the oxygenation index on the first postoperative day, along with secondary measures like sleep apnea index, hospital stay duration, pulmonary complications, delirium, and in-hospital mortality up to three months.
