NO
To observe the hemodynamic changes and time to loss of consciousness following the induction of general anesthesia with remimazolam in patients with severe aortic stenosis.
We will also collect data from patients who were used midazolam for induction of anesthesia retrospectively and compare them to remimazolam for hemodynamic and other changes.
Safety,Efficacy
Dosage of vasoconstrictor and inotropic agents during induction of anesthesia.
Hemodynamic change (blood pressure and heart rate).
Time to loss of consciousness, time from the start of anesthesia induction to the end of tracheal intubation, total remimazolam dose, change in BIS (bispectral index) level, change in TOI (tissue oxygenation index), postoperative nausea and vomiting, incidence of postoperative delirium, presence or absence of awareness at the time of induction of anesthesia, and postoperative flumazenil use and dose.
Observational
65 | years-old | <= |
Not applicable |
Male and Female
Patients with a diagnosis of severe aortic stenosis on a preoperative transthoracic echocardiogram.
(1) Patients undergoing emergency surgery
(2) Patients who are allergic to the study drugs (fentanyl, remifentanil, rocuronium, sugammadex, benzodiazepines, sevoflurane, desflurane)
(3) Patients for whom the use of remimazolam is contraindicated (patients with acute angle-closure glaucoma, myasthenia gravis, shock, coma, and acute alcoholism with suppressed vital signs)
(4) Patients with preoperative disturbance of consciousness
(5) Patients who have been sedated preoperatively
(6) Patients deemed inappropriate by the principal investigator/associators (excluded with reasons for exclusion)

In this study, we will use remimazolam for induction of general anesthesia in patients with severe aortic stenosis and observe hemodynamic changes, time to loss of consciousness, and so on.
The other observations of the study were as follows.
Age, gender, height, weight, ASA PS, comorbidities, NYHA classification, and Hugh-Jones classification.
Transthoracic echocardiographic measurements (LVDd/Ds, LVEF, E/A/DcT, E/e', maximal flow velocity through the aortic valve, maximal pressure gradient, mean pressure gradient, aortic valve area, left ventricular outflow tract blood flow velocity/aortic valve blood flow velocity, other degrees of valvular disease, tricuspid valve regurgitation pressure gradient, etc.)
Twelve-lead ECG readings: heart rate, presence of arrhythmia, etc.
Chest x-ray: cardiothoracic ratio, presence of pleural effusion
Blood test: Hemoglobin, BUN, creatinine, NT-proBNP, HbA1c
Time from the start of anesthesia induction to the end of tracheal intubation, blood pressure (systolic, diastolic, mean blood pressure) according to arterial pressure waveforms, heart rate, BIS level, cerebral tissue oxygenation.
The amount of remimazolam used, the type and amount of circulating agonists used (e.g. ephedrine, phenylephrine, atropin, noradrenaline, adrenaline, dobutamine, dopamine, and nicardipine)
Flumazenil use and dosage, operative time, postoperative ventilatory time, CAM-ICU (Confusion assessment method for the ICU) assessment of delirium, awareness at the time of intubation, nausea and vomiting up to the second postoperative day, and number of days in the ICU.
We will collect 40 background-matched patients' data with severe aortic stenosis who were previously induced with midazolam retrospectively (1:2 matching) and compare the dosage of vasoconstrictor and inotropic drugs, hemodynamic changes, incidence of postoperative delirium, and so on.
