Principles of anaesthesia
The principles of anaesthesia underly everything that you will encounter when considering how to deal with patients before and during operations:
- Analgesia - your main aim is to control pain, otherwise operations would be torture.
- Sedation - usually, the patient needs to be asleep, and so sedation is rather important for making this a reality.
- Muscle Relaxation - in some situations it is important to use muscle relaxants; for example tense rectus muscles do not help abdominal surgery.
Anaesthesia is all about altering the physiology of the body to achieve these things without killing the patient.
