Overview

General anaesthesia (GA) is a medically induced state of unconsciousness used during surgical procedures to prevent pain and discomfort. It involves administering a combination of intravenous (IV) drugs and inhaled gases that result in loss of consciousness, pain relief, and muscle relaxation. GA is commonly used in major surgeries, ensuring that the patient remains unaware and does not feel pain during the procedure.

How is General Anaesthesia Done?

Before undergoing general anaesthesia, several preparations are required:
Pre-Anaesthesia Assessment
  • Review of medical history, allergies, and past anaesthesia experiences.
  • Blood tests, ECG, and other diagnostic tests as needed
Fasting Guidelines
  • Patients are typically advised to stop eating 6–8 hours before surgery.
  • Clear liquids may be allowed up to 2 hours before surgery.
Medication Adjustments
  • Some medications may need to be stopped or adjusted before surgery.
  • Patients should inform their doctor about all medications, including supplements.
Consent and Counselling
  • The anaesthetist explains the procedure, risks, and benefits.
  • The patient signs a consent form before proceeding.

Induction Phase
  • IV medications (such as Propofol, Ketamine, or Etomidate) or inhaled gases (such as Sevoflurane) are used to induce unconsciousness.
  • Muscle relaxants may be administered to facilitate intubation.
Airway Management
  • A breathing tube (endotracheal tube) or a laryngeal mask airway (LMA) is inserted to maintain oxygen supply.
Maintenance Phase
  • Continuous administration of anaesthetic gases and IV drugs to keep the patient asleep and pain-free.
  • Vital signs (heart rate, blood pressure, oxygen levels) are closely monitored.
Emergence Phase
  • Anaesthetic agents are gradually reduced, and the patient starts regaining consciousness.
  • The breathing tube is removed once the patient can breathe independently.
Steps of General Anaesthesia
  • Preoperative Assessment and Patient Preparation
  • Induction of Anaesthesia (IV or inhaled drugs)
  • Airway Management and Ventilation
  • Maintenance of Anaesthesia
  • Monitoring Vital Signs Throughout Surgery
  • Emergence from Anaesthesia
  • Post-Anaesthesia Care and Recovery

While GA is generally safe, potential complications include:
Common Risks
  • Nausea and vomiting
  • Sore throat (from intubation)
  • Drowsiness and confusion
  • Chills or shivering
Serious Complications (Rare)
  • Allergic reactions to anaesthetic drugs
  • Breathing difficulties or aspiration pneumonia
  • Malignant hyperthermia (a rare, life-threatening reaction)
  • Cardiovascular complications (low blood pressure, heart attack)

Benefits of General Anaesthesia
  • Pain-Free Surgery: Complete elimination of pain perception.
  • Muscle Relaxation: Facilitates complex surgical procedures.
  • Controlled Unconsciousness: Prevents awareness during surgery.
  • Adjustability: Allows precise control of anaesthetic depth.

Infrastructure Facilities for General Anaesthesia

  • Operating Theatres with anaesthesia machines and monitoring systems.
  • Post-Anaesthesia Care Units (PACU) for patient recovery.
  • Intensive Care Units (ICU) for high-risk cases.
  • Specialised Anaesthesia Teams including anaesthetists, nurses, and technicians.
  • Emergency Resuscitation Equipment for managing complications.
