A quick heart check might flag who will crash after spinal anesthesia
NCT ID NCT07765342
First seen Aug 14, 2026 · Last updated Aug 14, 2026
Summary
This study looks at whether a simple heart measure, called the diastolic shock index, can predict a sudden drop in blood pressure after spinal anesthesia. It will include adults aged 50 and older having elective inguinal hernia surgery under spinal anesthesia. Researchers will record routine heart and blood pressure readings before and after the anesthesia to see if this index, along with other shock indices, can identify who is likely to develop postspinal hypotension. The goal is to improve safety by spotting at-risk patients early, without adding any extra procedures.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- No intervention is tested; the study observes routine spinal anesthesia and records hemodynamic parameters.
- What this could lead to
- If the diastolic shock index proves accurate, it could help doctors identify patients at higher risk of postspinal hypotension and take preventive steps.
- What could go wrong
- This is a small observational study, so results may not apply broadly. The index may not outperform existing measures, and no treatment is being tested.
