Summary

This study looked at 110 people with high blood pressure who were having surgery with spinal anesthesia. Researchers used ultrasound to measure blood vessel features before the anesthesia to see if they could predict a dangerous drop in blood pressure. The goal is to help doctors better prepare and manage these patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help doctors better predict and prevent dangerous drops in blood pressure during spinal anesthesia in patients with high blood pressure.
What could go wrong
This is an observational study, not a treatment trial. It only looks for links, not causes. The findings may not apply to all patients or settings.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study will include adult hypertensive patients scheduled for elective surgical procedures under spinal anesthesia at Konya City Hospital. The target population comprises patients with hypertensive patients (ASA II-III classification), who are deemed fit for elective surgery and spinal anesthesia by their clinical teams. Eligible participants will be screened based on inclusion and exclusion criteria. The study population represents a subset of hypertensive individuals with varying durations of hypertension, medication regimens, and cardiovascular profiles. Patients will be recruited from preoperative assessment clinics and surgical wards at the hospital.
