What is general anesthesia, and when is it used?

General anesthesia is a type of medication that induces a deep state of sleep, ensuring you are entirely unaware and pain-free during surgery. It is commonly used for major surgical procedures, such as heart surgeries, abdominal operations, or any operation where being fully conscious would be impractical or uncomfortable. By temporarily “turning off” your awareness and sensation, general anesthesia allows the surgical team to perform complex procedures efficiently while ensuring you experience no pain or distress.

What can I expect during and after general anesthesia is administered?

Before your surgery, the anesthesiologist will administer the anesthesia, typically either through an intravenous line or by having you inhale anesthetic gases. Within moments, you will drift into a deep sleep, completely unaware of your surroundings. Throughout the surgery, the anesthesiologist will remain by your side, continuously monitoring your vital signs—such as heart rate, blood pressure, and oxygen levels—and adjusting the anesthesia dosage as needed to maintain your safety and comfort.

After the procedure, you will gradually wake up in the recovery room. It’s normal to feel groggy or disoriented at first as the effects of the anesthesia wear off. Common mild side effects include a sore throat (from the breathing tube used during anesthesia), nausea, or a dry mouth. These side effects usually subside relatively quickly. The anesthesiologist will be present to ensure your comfort, manage any discomfort, and provide medications as necessary as you fully regain consciousness.

Overall, general anesthesia is a safe and effective way to ensure a pain-free experience during major surgeries. The anesthesiologist’s role is to manage this delicate process and support you from the moment you enter the operating room until you are fully awake and comfortable afterward.

What are the risks and complications associated with general anesthesia?

General anesthesia is a safe and commonly used technique that allows patients to undergo surgery without pain or awareness. While serious complications are rare, it’s important to understand the potential risks. Most side effects are mild and temporary, and your anesthesiologist will take steps to minimize these risks.

Common side effects

• Nausea and vomiting: You may feel sick after surgery, but medications are available to help prevent this.
• Sore throat: This can happen if a breathing tube is used during the procedure. It usually resolves within a day or two.
• Shivering or feeling cold: It’s common to feel cold after surgery, but warming measures are taken to keep you comfortable.
• Tiredness or drowsiness: Feeling groggy after anesthesia is normal and typically goes away within a few hours.

Less common but possible risks

• Breathing problems: Temporary breathing difficulties may occur during or after anesthesia but are carefully monitored.
• Heart issues: Changes in blood pressure or heart rate may happen but are managed immediately by your care team.
• Allergic reactions: Rare but possible with certain medications or substances used during surgery.

Rare but serious complications

• Aspiration: If stomach contents enter the lungs, it can cause lung irritation or infection. This is why fasting before surgery is important.
• Awareness during anesthesia: Extremely rare, but measures are taken to prevent it.
• Malignant hyperthermia: A rare genetic reaction to certain anesthetic drugs. Your care team is trained to manage this emergency.
