    before induction, 20 minutes

Secondary Outcomes (5)

  • ClearSight SVV

    before induction, 20 minutes

  • normal ventilation △IVC (inferior vena cava) diameter

    before induction, 20 minutes

  • augmented ventilation △IVC (inferior vena cava) diameter

    before induction, 20 minutes

  • normal ventilation △POP (pulse oximeter plethysmography)

    before induction, 20 minutes

  • augmented ventilation △POP (pulse oximeter plethysmography)

    before induction, 20 minutes

Study Arms (2)

Fluid challenge responder

EXPERIMENTAL

If the ratio of the stroke volume change after passive leg raising is the same or larger than 10%, the patient is assigned to RESPONDER group.

Diagnostic Test: Passive leg raising

Fluid challenge non-responder

EXPERIMENTAL

If the ratio of the stroke volume change after passive leg raising is less than 10%, the patient is assigned to RESPONDER group.

Diagnostic Test: Passive leg raising

Interventions

Passive leg raisingDIAGNOSTIC_TEST

Raise the patient's lower limb at a 45 degree angle while lying down

Eligibility Criteria

Age19 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • for patients undergoing surgery under actual spinal anesthesia whose estimated blood loss during surgery is moderate to high (e.g. total knee arthroplasty, total hip arthroplasty)
  • Patients with a history of cerebrovascular disease
  • Patients with a history of 1 or 2 vessel disease
  • Left ventricle ejection fraction (LVEF) Patients with 30% or more and less than 55% of these patients
  • Patients who need close hemodynamic monitoring during operation
  • ASA (American Society of Anesthesiology) physical status classification system I, II, III
  • no difficulty in passive leg raising maneuver

You may not qualify if:

  • Patients unable to communicate
  • Patients who cannot or have difficulty in PLR (passive leg raising) maneuver (patients who cause pain when performing PLR due to trauma of the lower extremities, patients with spine disease that causes pain during PLR, and patient applying splint due to a fracture of the lower extremity)
  • Patients unable to attach the finger cuff of the ClearSight sytem to one of the fingers of both hands. (Patients applying a splint due to a fracture of both upper limbs, etc.)
  • Patients unable to perform transthoracic ultrasound examination (multiple trauma patients with rib fracture, etc.)
  • Patients having difficulty obtaining blood pressure waveforms through the ClearSight system due to poor peripheral vascular perfusion (uncontrolled diabetes patients, patients with peripheral vascular disease, etc.)
  • Patients with arrhythmia with moderate or higher risk such as atrial fibrillation or atrial flutter
  • Heart failure patients with less than 30% of the left ventricular ejection fraction(LVEF) on echocardiography or patients with moderate to severe left ventricular wall motor dysfunction, or patients with cardiovascular disease of 3 vessel disease
  • Other patients who are not appropriate to participate in the study as judged by the researcher
