Is anaesthesia safe before surgery?
Anaesthesia is generally safe for most patients when administered by a qualified anaesthetist after a thorough pre-operative assessment. Serious complications are uncommon in healthy individuals. Deccan Hardikar Hospital in Pune provides anaesthesiology services across orthopaedic, general surgical, and other speciality procedures, with patient safety protocols at every stage.
Note: Your anaesthetist will review your full medical history, current medications, and any allergies before recommending the most appropriate type of anaesthesia for your procedure.
What are the 4 types of anaesthesia used in surgery?
The type of anaesthesia chosen depends on the procedure, the patient's health status, and the surgeon's requirements. At Deccan Hardikar Hospital in Pune, the anaesthesiology team selects the most appropriate approach for each patient.
| Type | What It Does | Common Uses |
|---|---|---|
| General Anaesthesia | Renders the patient fully unconscious | Major orthopaedic, abdominal, and cardiac surgeries |
| Regional Anaesthesia | Numbs a large area of the body (e.g. spinal or epidural block) | Knee replacement, hip replacement, lower limb procedures |
| Local Anaesthesia | Numbs a small, specific area | Minor wound repairs, skin procedures, small joint injections |
| Sedation (Monitored Anaesthesia Care) | Induces a relaxed, drowsy state without full unconsciousness | Endoscopy, minor diagnostic procedures, fracture manipulation |
What are the risks of anaesthesia during surgery?
Anaesthesia carries a small but real set of risks. The likelihood and severity depend on the patient's age, overall health, type of surgery, and the anaesthesia technique used. Understanding these risks helps patients make informed decisions.
- Nausea and vomiting — the most common side effect after general anaesthesia, usually short-lived.
- Sore throat or hoarseness — may occur if a breathing tube was used.
- Shivering and confusion — temporary disorientation on waking, more common in older adults.
- Allergic reactions — rare but possible with certain anaesthetic drugs.
- Breathing difficulties — risk is higher in patients with obstructive sleep apnoea or obesity.
- Awareness under anaesthesia — very rare; the patient may have partial consciousness during the procedure.
- Serious cardiovascular events — uncommon; risk increases with pre-existing heart or lung conditions.
Warning: Patients with uncontrolled diabetes, severe hypertension, or significant cardiac disease face a higher anaesthetic risk. Disclose all medical conditions and medications to your anaesthetist before surgery.
For orthopaedic procedures such as joint replacement surgery, regional anaesthesia techniques such as spinal blocks are often preferred because they reduce systemic drug exposure and support faster recovery.
Is general anaesthesia safe for elderly patients?
Elderly patients can safely undergo general anaesthesia, but they require more careful pre-operative evaluation. Age-related changes in organ function, metabolism, and drug clearance mean that anaesthetic drugs may act differently and take longer to leave the system.
Key considerations for older patients include:
- Reduced kidney and liver function slows drug metabolism — doses are adjusted accordingly.
- Higher risk of post-operative cognitive dysfunction (POCD) — temporary memory and concentration changes after surgery.
- Greater likelihood of pre-existing conditions such as hypertension, diabetes, or heart disease that must be optimised before the procedure.
- Increased sensitivity to sedative and anaesthetic agents.
- Higher risk of dehydration and electrolyte imbalance in the peri-operative period.
Regional anaesthesia (spinal or epidural) is often preferred for elderly patients undergoing lower-limb orthopaedic procedures, as it avoids the systemic effects of general anaesthesia while providing effective pain control.
What should I tell my anaesthetist before surgery — and can I eat or drink beforehand?
A pre-anaesthesia consultation is a critical safety step. Being thorough and honest during this assessment directly reduces your risk of complications.
What to disclose to your anaesthetist:
- All current medications, including over-the-counter drugs, supplements, and herbal remedies
- Known allergies — especially to drugs, latex, or anaesthetic agents
- Previous reactions to anaesthesia (personal or family history)
- Chronic conditions: diabetes, hypertension, asthma, heart disease, kidney or liver disorders
- History of obstructive sleep apnoea or snoring
- Smoking, alcohol use, or recreational drug use
- Dental crowns, loose teeth, or jaw problems (relevant for airway management)
- Pregnancy or possibility of pregnancy
Fasting guidelines before anaesthesia:
- No solid food for at least 6 hours before surgery.
- No milk or heavy liquids for at least 6 hours before surgery.
- Clear fluids (water, black tea without milk) may be permitted up to 2 hours before — confirm with your surgical team.
- Take prescribed medications with a small sip of water only if instructed by your anaesthetist.
Tip: Eating or drinking within the restricted window increases the risk of aspiration (stomach contents entering the lungs) during anaesthesia — a potentially serious complication. Always follow your team's specific instructions.
When should you consult an anaesthetist before your procedure?
Most patients meet their anaesthetist during a pre-operative assessment, typically scheduled 24–72 hours before elective surgery. However, certain situations warrant an earlier or more detailed consultation.
Seek an anaesthesia consultation promptly if you:
- Have a known heart condition, irregular heartbeat, or have had a cardiac event in the past 6 months
- Have poorly controlled diabetes or blood pressure
- Have a history of difficult intubation or airway problems
- Are taking blood thinners (anticoagulants) that may need to be paused before surgery
- Have had a previous adverse reaction to anaesthesia
- Are scheduled for a major procedure such as joint replacement surgery and have multiple co-existing conditions
- Are over 70 years of age with two or more chronic conditions
Do not wait until the day of surgery to raise concerns. Early consultation allows the anaesthesiology team to optimise your condition and select the safest anaesthetic plan.
