About this study
Official title: Perioperative Hypothermia and Sevoflurane Consumption in Elderly Patients Undergoing Hip Arthroplasty
This prospective observational study aims to evaluate the association between perioperative hypothermia and sevoflurane consumption in elderly patients undergoing hip arthroplasty under general anesthesia. Patients aged 65 years and older will be included. Perioperative body temperature and anesthetic consumption will be recorded, and the relationship between hypothermia and anesthetic requirements will be analyzed. The findings may help clarify whether hypothermia influences anesthetic depth monitoring and anesthetic consumption in elderly surgical patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Perioperative Hypothermia, run by Sultan Abdulhamid Han Training and Research Hospital, Istanbul, Turkey.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 12 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Sevoflurane consumption (mL/hour) (time frame: Intraoperative period). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Mar 2026.
