Types of Anaesthesia:

1. General Anaesthesia:

• Patient becomes completely unconscious.
• Used for major surgeries.
• Delivered through inhaled gases or intravenous (IV) drugs.

2. Regional Anaesthesia:

• Blocks pain in a larger area of the body (e.g., spinal, epidural, or nerve block).
• Patient remains awake but numb in the targeted region.

3. Local Anaesthesia:

• Numbs only a small, specific area.
• Used for minor procedures (e.g., dental work, skin surgery).

4. Sedation (Conscious Sedation / Twilight Anaesthesia):

• Patient is relaxed and drowsy, but not fully unconscious.
• Often combined with local anaesthesia.

Key Roles of an Anaesthesiologist:

• Assess patient’s health before surgery.
• Decide the safest anaesthesia method.
• Monitor vital signs (heart rate, blood pressure, oxygen) during the procedure.
• Manage pain after surgery.

Risks & Safety:

• Common mild side effects: nausea, sore throat, dizziness, shivering.
• Rare but serious risks: allergic reaction, breathing issues, heart complications.
• Safety is very high today due to advanced drugs and monitoring equipment.

Anaesthesia List:

In short: Anaesthesia is essential for modern surgery, providing comfort, pain control, and safety during medical procedures.
