Brief 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 we will compare the inter-limb blood pressure differences before anesthesia induction and during general anesthesia
Detailed Description:
Non-invasive blood pressure measurement during surgery is typically conducted on the upper arm and previous studies about the relationship between intraoperative blood pressure fluctuation and postoperative mortality and morbility have also based on the upper arm measurements However in clinical practice if monitoring blood pressure in the upper arm is not feasible during surgery the cuff usually be placed on the ankle
According to a previous study the systolic blood pressure at the ankle is approximately 170 mmHg higher than the systolic blood pressure at the arm in the supine position 95 CI 154-213 mmHg while the diastolic blood pressure did not show significant differences in awake state Since the hemodynamic state of patients under anesthesia differs from that of awake patients there is insufficient evidence to directly apply the known differences between upper and lower limb blood pressures in awake patients to set target blood pressure ranges during anesthesia As a result anesthesiologists often rely on clinical judgment in these situations
Therefore this study sets the null hypothesis that the differences in blood pressure between the upper and lower limbs before and after anesthesia are the same The goal is to determine whether the previously known relationship between upper and lower limb blood pressures in awake patients can be applied to patients under general anesthesia Additionally this study aims to investigate the relationship between upper and lower limb blood pressures when the lower limb blood pressure is outside the normal range during general anesthesia
