Brief Summary
Post-induction hypotension (PIH) is a common occurrence during the period from induction of general anesthesia to initiation of incision. PIH has been identified as an independent risk factor for postoperative major complications. Identifying high-risk patients for PIH could potentially help prevent its occurrence. Several risk factors associated with PIH have been identified, including patient conditions and use of specific anesthetic agents. Ventricular-arterial coupling (VAC) is evaluated using the ratio Ea/Ees and represents the interaction between the left ventricle (LV) and the arterial system. It reflects how changes in LV contractility (Ees) and changes in arterial load (Ea) work together to maintain optimal LV performance. A study aims to investigate the relationship between preoperative Ea/Ees ratio and the incidence of PIH (defined as MAP \< 65 mmHg).

Eligibility Criteria
Patients with American Society of Anesthesiologists (ASA) physical status 1 - 4 who underwent elective surgery
You may qualify if:
- Patients ≥ 18 years old.
- Patients with ASA (American Society of Anesthesiologists) physical status 1 - 4.
- Elective surgery.
- Preoperative transthoracic echocardiography was performed within 48 hours before surgery. The values of Ees and Ea were determined by the method of Chen.
- Patients consented to participate in the study.
- Patients scheduled for surgery undergoing standard general anesthesia (protocol: see below) with endotracheal intubation.
- Patients were hemodynamically stable until the preoperative period.
You may not qualify if:
- Cardiac and obstetric surgery.
- Allergy to any anesthetic drug.
- Arrhythmia.
- Severe valvular heart disease.
- Severe pre-existing lung disease.
- Mean pulmonary arterial pressure (PAPm ≥ 40 mmHg).
- Anticipation of difficult airway management.
- Hypotension occurs during the induction of anesthesia due to suspected anaphylaxis.
