Examining blood pressure differences in thyroid surgery patients under anesthesia

The Relationship Between Upper and Lower Extremity Blood Pressure in Thyroid Surgery Patients Under General Anesthesia

Ilsan Cha hospital · NCT06590064

This study is trying to see if blood pressure readings from the arm and ankle are different in patients having thyroid surgery while under anesthesia, to help doctors manage blood pressure better during the procedure.

What this trial studies

This observational study aims to clarify the relationship between upper and lower limb blood pressure in patients undergoing elective thyroid surgery under general anesthesia. It will compare blood pressure measurements taken from the upper arm and ankle before anesthesia induction and during the procedure. The study seeks to determine if the known differences in blood pressure between these limbs in awake patients apply to those under anesthesia, addressing a gap in current clinical practice. By doing so, it hopes to provide insights that could improve intraoperative blood pressure management.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 to 80 years undergoing elective thyroid surgery under general anesthesia with ASA Physical Status Class I or II.

Not a fit: Patients with diabetes, heart disease, arrhythmias, or other conditions that affect blood pressure measurement may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of blood pressure monitoring during thyroid surgeries, potentially improving patient outcomes.

How similar studies have performed: While there is existing literature on blood pressure differences in awake patients, this specific approach under general anesthesia is novel and has not been extensively tested.
