Chilly patients may need more anesthesia during hip surgery, study suggests

This study will observe 70 elderly patients (65 and older) undergoing hip replacement surgery to see if getting cold during the operation changes how much anesthesia they need. Researchers will measure body temperature and track the amount of sevoflurane (a common anesthetic gas) used. The goal is to better understand how hypothermia affects anesthesia needs in older adults, which could help improve surgical care.
