Internal jugular (neck) ultrasound to predict low blood pressure after spinal anesthesia in older adults
Official title: The Role of Internal Jugular Vein Ultrasonography in Predicting Hypotension in Geriatric Patients Undergoing Spinal Anesthesia: A Prospective Observational Study (Protocol ID: 2023-12/509)
Run by Dr Abdurrahman Yurtaslan Ankara Oncology Training and Research Hospital · NCT07411313 · Data updated 2026-11-12
We try to see if a quick ultrasound of the internal jugular vein before spinal anesthesia can predict which people aged 65 and older will develop low blood pressure.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 65 or older scheduled for elective surgery under spinal anesthesia with ASA physical status I–III who can give informed consent and tolerate the supine position are ideal candidates.
✕Probably not a fit
Patients undergoing emergency surgery, requiring conversion to general anesthesia or sedoanalgesia, with BMI ≥40, on ACE inhibitors, pre-spinal hypotension, or left ventricular ejection fraction <40% are unlikely to benefit from the predictive approach tested here.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Older adults receiving spinal anesthesia commonly experience clinically important drops in blood pressure, and preoperative intravascular volume status may help identify those at risk. This prospective observational study will enroll elective surgical patients aged 65 years and older and obtain supine preoperative ultrasound measurements of the internal jugular vein (diameter, cross-sectional area, and collapsibility index). Intraoperative systolic/diastolic blood pressure and heart rate will be monitored and episodes of hypotension after spinal anesthesia recorded. The analysis will test whether baseline IJV ultrasound parameters predict post-spinal hypotension.
Why it matters
Potential benefit: If successful, clinicians could identify older patients at higher risk of post-spinal hypotension and apply targeted preventive measures before anesthesia.
How similar studies have gone: Prior small observational studies have suggested IJV ultrasound correlates with venous filling and may help predict hypotension, but results have been mixed and not yet definitive.
