General Anaesthesia Is Very Common
- Nearly 3 million general anaesthesia procedures happen yearly in the UK, so most people will likely experience it.
- General anaesthesia is used for major or long surgeries and renders patients completely unconscious.
Follow Pre-Surgery Instructions
- Follow pre-surgery instructions: fast for about six hours and take any prescribed pre-medication to relax.
- These steps help reduce complications and prepare you for safe induction of anaesthesia.
Anaesthesia Uses A Three-Drug Combination
- General anaesthesia combines a hypnotic, an analgesic, and a muscle relaxant to induce deep sleep and suppress reflexes.
- Medications are given intravenously or by inhalation and also prevent pain and movement during surgery.
