Comprehensive anesthetic method in which the patient is put to sleep and pain sensation and consciousness are fully suppressed, applied for surgical procedures.
Indication
- Major surgical procedures (abdominal, thoracic, orthopedic, cardiac, neurosurgical)
- Conditions in which regional anesthesia is unsuitable or contraindicated
- Long and complex operations
- Procedures in pediatric patients that require cooperation
- Emergency surgical situations (trauma, acute abdomen)
- Suitable cases in which the patient prefers general over regional anesthesia
- Procedures requiring full control of airway safety
Preparation
- Pre-anesthetic evaluation (preoperative assessment), blood tests, ECG, and chest X-ray when needed
- Discontinuation of solid food 6-8 hours and clear liquids 2 hours before the procedure (fasting rules)
- Adjustment of blood thinners, diabetes medications, and certain chronic medications with physician approval
- Cessation of smoking and alcohol at least 24 hours in advance
- Reporting known drug allergies, previous anesthesia experiences, and family history (e.g., malignant hyperthermia)
How it's performed
- An IV line is established; heart rhythm, blood pressure, and oxygen levels are continuously monitored
- Induction agents are administered intravenously by the anesthesiologist
- After the patient is asleep, the airway (endotracheal tube or laryngeal mask) is placed
- Anesthesia is maintained throughout surgery with anesthetic gas or intravenous medications
- Vital signs and depth of anesthesia are continuously monitored by the specialist team
- At the end of the procedure, medications are stopped, the patient is awakened, and the breathing tube is removed
Post-procedure
- Observation for 30-60 minutes in the recovery room (postoperative care unit)
- Assessment for nausea, pain, and shivering; treatment if needed
- During the first hours, driving, important decision-making, and operating machinery are prohibited (24 hours)
- Sore throat and hoarseness after anesthesia usually resolve within 24-48 hours
- Immediate medical attention in case of unusual symptoms (high fever, muscle stiffness, shortness of breath)
Risks
- Nausea, vomiting, and transient sore throat (common, mild side effects)
- Drug allergy and anaphylactic reactions (rare)
- Injury to teeth, lips, or vocal cords during the procedure (rare)
- Cardiopulmonary complications in patients with high ASA risk class
- Malignant hyperthermia — a very rare but serious reaction to anesthetic gases in genetically susceptible individuals
FAQ
Is there a risk of waking up during general anesthesia?
Intraoperative awareness is extremely rare with modern anesthesia equipment and continuous monitoring. Depth of anesthesia is tracked with dedicated monitors.
Why do I need to fast before anesthesia?
Fasting is essential to prevent stomach contents from entering the lungs (aspiration). Generally, solid food is stopped 6-8 hours and clear liquids 2 hours beforehand.
Will anesthesia affect my memory or mind?
Mild forgetfulness may occur in the first 24 hours. No lasting cognitive effects are expected in healthy adults; transient grogginess can be more common in older age and after long surgeries.
Anesthesia problems have occurred in my family — am I at risk too?
Rare conditions such as malignant hyperthermia can run in families. Always inform your anesthesiologist; if necessary, a different medication protocol will be used.
