Is this trial a fit for you?
✓Likely a good fit
Adults aged 60 years and older undergoing elective laparoscopic colorectal surgery under general anesthesia.
✕Probably not a fit
Patients without significant IJV collapsibility changes or those with exclusions may not derive benefit from this measurement.

What this trial studies
This observational study examines if the collapsibility of the internal jugular vein, measured with bedside ultrasound, can predict intraoperative hypotension in older adults. It compares IJV collapsibility index to hemodynamic events during elective laparoscopic colorectal procedures. Patients are 60 years or older and scheduled for general anesthesia, with certain cardiac and rhythm exclusions. The goal is to see if a simple venous ultrasound metric can help anticipate and potentially prevent drops in blood pressure during surgery.
Why it matters
Potential benefit: If successful, the approach could help anesthesiologists anticipate hypotension and tailor fluid or vasopressor management for at-risk patients.
How similar studies have gone: Prior research has shown correlations between venous collapsibility indices and central venous pressure, supporting the concept but with varying methodologies.
