Intermittent measurement of urine oxygen tension using a novel urine collection device

JRCT ID: jRCT1032240147

Registered date:10/06/2024

Basic Information

• Recruitment status: Pending
• Health condition(s) or Problem(s) studied: Ischemic heart disease, heart valvular disease, thoracic aortic aneurysm, dissecting aortic aneurysm
• Date of first enrollment: 10/06/2024
• Target sample size: 12
• Study type: Observational

Outcome(s)

• Primary Outcome: Changes in urine oxygen tension and the percentage of urine that can be collected from new devices
• Secondary Outcome: Agreement of measured urine oxygen tension with previous studies, comparison of measurement error between blood gas devices, correlation between arterial blood oxygen partial pressure and urine oxygen tension, correlation of arterial blood oxygen partial pressure and central venous blood oxygen partial pressure to urine carbon dioxide tension, relationship between trends in urine oxygen tension and acute kidney injury
