Anesthesia

Surgery & Procedures

Anaesthesia is the use of medicines and techniques to keep you pain-free during surgery or procedures. It is remarkably safe in modern Indian hospitals with trained anaesthetists, but it is a real medical event — and a pre-operative conversation with the anaesthetist matters as much as with the surgeon.

Anaesthesia is the use of medicines and techniques to keep you pain-free during surgery or procedures. It is remarkably safe in modern Indian hospitals with trained anaesthetists, but it is a real medical event — and a pre-operative conversation with the anaesthetist matters as much as with the surgeon.

Main types

  • Local anaesthesia — numbs a small area (stitching a cut, dental work). You stay fully awake.
  • Regional anaesthesia — numbs a larger region. Spinal and epidural anaesthesia for lower-body surgery (caesarean, knee replacement, prostate, hernia); nerve blocks for limb surgery.
  • Sedation ("twilight anaesthesia") — drowsy and comfortable, often combined with local anaesthesia; used for endoscopy, some minor surgeries.
  • General anaesthesia — fully unconscious, with breathing support and close monitoring.

Pre-op assessment

  • The anaesthetist will review past surgeries, medical conditions, allergies, and all medicines (including herbal / Ayurvedic / gym supplements).
  • Some conditions need optimisation first — anaemia, uncontrolled BP/sugar/thyroid, sleep apnoea, recent chest infection.
  • Investigations (ECG, blood tests, chest X-ray) as needed — not every patient needs all of them.
  • Fasting instructions — usually no solid food 6–8 hours before, clear fluids till 2 hours before (unless told otherwise).

Risks — in context

  • Serious complications are rare with trained anaesthetists and modern monitoring.
  • Common minor issues: nausea/vomiting, sore throat, shivering, headache (after spinal), mild confusion in older adults.
  • Rare serious issues: severe allergic reaction, aspiration, awareness under anaesthesia, nerve injury, cardiovascular events.
  • Malignant hyperthermia — rare inherited reaction; tell the team of any family history of bad anaesthetic reactions.

After anaesthesia

  • Don't drive, operate machinery, or make legal/financial decisions for 24 hours after general anaesthesia or sedation.
  • Don't drink alcohol for 24 hours.
  • Post-op pain control is much better than even a decade ago — don't suffer silently; ask for pain medicine.
  • Sip fluids first; build up to light food; watch for nausea.

Special notes

  • Pregnancy — obstetric anaesthesia (epidural for labour, spinal for caesarean) is safe and effective; discuss preferences antenatally.
  • Children — child-friendly approaches (oral sedation, parental presence) at good paediatric centres.
  • Sleep apnoea, morbid obesity, difficult airway — tell the anaesthetist early; it changes planning.
  • Ayurvedic/herbal products — stop at least 1 week before elective surgery; several cause bleeding or anaesthetic interactions.
