NCT06590064

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, the investigators will compare the inter-limb blood pressure differences before anesthesia induction and during general anesthesia.

Outcome Measures

Primary Outcomes (2)

  • d_MBP(awake)

    Difference between upper and lower extremities mean blood pressure in awake state

    Simultaneously measured values in operating room before anesthesia induction

    Simultaneously measured values in operating room before anesthesia induction

  • d_SBP(GA)

    Simultaneously measured values during general anesthesia in a stable state without significant stimulation

  • d_DBP(awake)

    Simultaneously measured values in operating room before anesthesia induction

  • d_DBP(GA)

    Simultaneously measured values during general anesthesia in a stable state without significant stimulation

Study Population

Patients receiving elective thyroid surgery under general anesthesia

You may qualify if:

  • 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

You may not qualify if:

  • 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.
