About this study

Official title: Postoperative Complications of Orthopedic Surgery in Patients From High-altitude Regions: a Cohort Study.

This study will focus on orthopedic surgery patients from high-altitude regions, utilizing smart wearables and monitoring tools to gather perioperative data, including heart rate, oxygen saturation, sleep quality, stress levels, and other relevant metrics. Regular follow-ups will assess recovery and complications, in addition to collecting medical records, lab results, imaging data, and other pertinent records. The ultimate goal is to establish a comprehensive follow-up cohort of orthopedic surgery patients from high-altitude areas.

Read the detailed description

Prolonged exposure to hypoxic and low-pressure environments leads to structural remodeling and functional abnormalities in the cardiovascular, respiratory, and hematological systems of high-altitude populations. This elevates the risk of postoperative complications, particularly in patients undergoing orthopedic surgery, significantly impacting their recovery and quality of life. This study will focus on orthopedic surgery patients from high-altitude regions. Using smart wearable devices and other monitoring tools, comprehensive perioperative dynamic data of participants, including heart rate, heart rate variability, oxygen saturation, respiratory rate, sleep quality, activity levels, stress index, and other relevant indicators will be collected. Regular follow-ups will be conducted to evaluate postoperative recovery and monitor the incidence of perioperative complications. Additionally, perioperative data such as electronic medical records, laboratory test results, ECG waveforms, echocardiography, chest CT images, and other pertinent records will be also collected. Through that, this study aims to establish a follow-up cohort of orthopedic surgery patients from high-altitude regions.

Questions about this trial

What is this clinical trial studying?

An observational study of Orthopedic Surgery and Postoperative Complications, run by West China Hospital.

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 4 inclusion and 4 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 15 Oct 2024. 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.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Chunling Jiang, PhD (+86 02885422114, jiangchunling@scu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative venous thromboembolism (time frame: During hospitalization). 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 15 Oct 2024.
