Anesthesia helps the patient to lie still, does not worry, does not feel pain and is important to ensure patient safety during surgery. Excessive pain and fear can lead to a fatal reflex cardiac arrest.
Procedures in cardiovascular surgery anesthesia are as follows:
Pre-anesthesia: Used 30-60 minutes before transferring the patient to the operating room, pre-anesthesia reduces patient anxiety, allows proceed to place monitoring devices without adversely affecting the hemodynamic status of the patient. Induction of anesthesia: The drugs used in cardiac surgery anesthesia are a combination of intravenous drugs used to induce anesthesia, including: analgesics of the Morphine family (Fentanyl, Sufentanyl), sleeping pills (Propofol, Etomidate), muscle relaxants (Esmeron, Arduan) and volatile anesthetics (Sevoran, Desfluran). The choice of anesthetic agent depends on the cardiac status, age, and aggravating factors. The anesthetic of choice should avoid myocardial depression, vasodilation, tachycardia, bradycardia, excessive fluid infusion, and/or hypovolemia. Maintenance of anesthesia: Maintenance of anesthesia is often used in combination with low-dose morphine analgesics, hypnotics, halogenated volatile anesthetics, and muscle relaxants. During surgery-anesthesia, the patient was monitored all parameters of vital functions (pulse, temperature, blood pressure, central venous pressure, oxygen saturation, exhaled CO2 concentration, respiratory rate, etc.) ), monitor anesthesia, monitor muscle tenderness. The anesthesiologist will adjust the appropriate anesthesia for each stage of the surgery.

Drugs commonly used in anesthesia for cardiac surgery include:
Pre-anesthesia: In cardiovascular surgery, pre-anesthetic drugs are often used: Atarax, Midazolam. Anesthesia: The drugs used in cardiac surgery anesthesia are combinations of drugs used to induce anesthesia, reduce anxiety, analgesia, muscle relaxants, and volatile anesthetics. The anesthetic agents include: Propofol, Etomidate. Depending on the type of heart disease and the specific patient's condition, there is a safe choice of drugs. These drugs must be used in combination with morphine analgesics and muscle relaxants to facilitate intubation. Sedatives: Midazolam, Propofol, Lorazepam. Midazolam is a drug with many advantages and is widely used in general anesthesia and open-heart surgery anesthesia in particular. Propofol is an intravenous anesthetic commonly used in open-heart surgery, with fast anesthetic effect, rapid awakening, and good anesthetic quality. Pain relievers: Fentanyl, Sufentanil, Alfentanil, Remifentanil. In particular, pain relievers Fentanyl, Sufentanil are commonly used in anesthesia in Vietnam. Muscle relaxants: Rocunium, Pancuronium, Vecuronium,... Maintenance of anesthesia: This stage is used in combination with low-dose morphine analgesics (fentanyl, sufentanil or alfentanil), tranquilizers (midazolam or propofol), narcotic drugs. Halogenated anesthetics and muscle relaxants (Pancuronium is a commonly used muscle relaxant because it increases both heart rate and blood pressure and reduces the bradycardia and blood pressure lowering effects of these drugs). central analgesics). At Vinmec, the use of morphine analgesics is limited. Instead, patients are controlled by vertebral plane anesthesia (with continuous infusion catheter) to increase pain relief and reduce side effects. of the morphine family of drugs.
