Anesthesia
Conditions
Brief summary
Ciprofol, a novel intravenous general anesthetic with a chemical structure akin to propofol, boasts significantly enhanced potency. It offers a rapid onset, reduced incidence of injection pain, and minor impact on the cardiovascular system. However, clinical research regarding ciprofol's use for anesthesia induction in cardiac surgery remains limited. The investigators want to assesse the safety and effectiveness of ciprofol in cardiac surgery anesthesia
Interventions
Patients in ciprofol group 0.3 mg/kg ciprofol for induction of anesthesia
Patients in propofol group received 1.5 mg/kg propofol for induction of anesthesia

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean arterial pressure | 1 second before induction of anesthesia (T1) | an average blood pressure in an individual during a single cardiac cycle |
| Heart beats | 1 second before induction of anesthesia (T1) | the number of times each minute that heart beats |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Oxygenation index | 1 second before induction of anesthesia (T1) | a calculation used in intensive care medicine to measure the fraction of inspired oxygen (FiO2) and its usage within the body. |
| Injection pain | During procedure (When injecting the drug, ask the subject if the injection site is painful) | Pain at the injection site when injecting the drug(Evaluation with Visual Analogue Scale) |
