The Relationship Between Upper and Lower Extremity Blood Pressure in Thyroid Surgery Patients Under General Anesthesia
South Korea170 participantsStarted 2024-07-15
Plain-language summary
The goal of this observational study is to clarify the relationship between upper and lower limb blood pressure in thyroid surgery patients under general anesthesia. The hemodynamic state during anesthesia is different from that during the awake state. Therefore, to assess whether the difference in blood pressure between the upper and lower limbs observed in the awake state is consistent with that observed under general anesthesia, the investigators will compare the inter-limb blood pressure differences before anesthesia induction and during general anesthesia.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Patients having elective thyroid surgery under general anesthesia
* Aged between 20 to 80 years old
* American Society of Anesthesiologist(ASA) Physical Status Class I or II
* Individuals who have voluntarily given written consent to participate in this clinical study
Exclusion Criteria:
* Patients with Diabetes Mellitus or Peripheral vascular disease
* Patients with a history of Heart disease; Myocardial infarction, Heart failure, etc.
* Patients with Arrhythmia
* Patients with musculoskeletal abnormalities
* Patients for whom the placement of a non-invasive blood pressure cuff is contraindicated: inflammatory diseases or wounds causing pain at the cuff site, severe edema, thrombophlebitis, etc.
* Other cases deemed unsuitable for the study by the researcher: absence of appropriately sized blood pressure cuffs, placement of a pressurized blood pressure cuff expected to affect the induction and maintenance of general anesthesia, history of mental illness, etc.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
