                             How General Anesthesia Works During Cardiac Surgery

Open-heart surgery is one of the most advanced procedures in modern medicine, and general anesthesia plays a vital role in making it safe, painless, and comfortable for patients. Whether you are undergoing coronary artery bypass grafting (CABG), heart valve surgery, or another complex cardiac procedure, the anesthesia team carefully monitors every heartbeat, breath, and vital sign throughout the operation.

At Aster RV Hospitals, Dr. Divakar Bhat, regarded by many patients as one of the Best Open Heart Surgeons in Bangalore, works closely with experienced cardiac anesthesiologists to ensure every patient receives safe and personalized anesthesia care.

What is general anesthesia?

General anesthesia is a combination of medications that places you in a controlled, sleep-like state during surgery. It completely blocks pain, prevents awareness of the procedure, and relaxes the muscles, allowing surgeons to perform complex heart operations with precision.

Unlike natural sleep, general anesthesia is continuously monitored and adjusted by a specialized cardiac anesthesiologist who remains with you throughout the procedure.

How general anesthesia works during cardiac surgery

Before surgery begins, anesthesia medications are administered through an intravenous (IV) line, and sometimes inhaled anesthetic gases are used. Within minutes, you fall into a deep unconscious state.

Once asleep, a breathing tube is inserted into your windpipe, and a ventilator supports your breathing throughout the surgery. During cardiac procedures, the anesthesia team continuously monitors:

• Heart rate and rhythm
• Blood pressure
• Oxygen levels
• Carbon dioxide levels
• Body temperature
• Fluid balance
• Blood loss
• Organ function

These measurements help the anesthesiologist precisely adjust medications, fluids, and blood products to keep your body stable throughout the operation.

The stages of general anesthesia

General anesthesia progresses through carefully controlled stages:

Stage 1 – Induction: Medications help you relax and drift into unconsciousness. Stage 2 – Excitement: A brief transition phase that is quickly managed by the anesthesiologist. Stage 3 – Surgical anesthesia: This is the ideal stage for surgery. You remain unconscious, pain-free, and your muscles are completely relaxed. Stage 4 – Overdose: Modern monitoring systems and advanced anesthesia techniques make this stage extremely rare. Preparing for general anesthesia Before your cardiac surgery, your anesthesiologist will review your:

• Medical history
• Current medications
• Allergies
• Previous anesthesia experiences
• Smoking or alcohol history

You will usually be instructed not to eat or drink for at least eight hours before surgery to reduce the risk of complications. Some medications, particularly blood thinners, may need to be stopped under your doctor’s guidance.

What happens after surgery?

Once the procedure is complete, anesthesia medications are gradually discontinued. You are transferred to the Cardiac Intensive Care Unit (CICU), where you wake up under close observation. The breathing tube is removed when you are awake enough to breathe independently.

It is normal to experience temporary effects such as:

• Drowsiness
• Sore throat
• Dry mouth
• Mild nausea
• Shivering
• Muscle aches

These symptoms usually resolve within a short period.
