ANAESTHESIA 1. INTRODUCTION Surgical treatment of disease requires gaining access to deeper tissues through the skin.
* The skin being a sensitive organ, is well provided with sensory nerves.
* Thus, it becomes important to interrupt the sensory pathways of skin, and deeper tissues (anaesthesia) if surgical access is to be provided.
* There are essentially two primary modes of rendering a patient insensitive to pain while undergoing surgical procedures:
- General anesthesia (central nervous system depression)
- Regional anesthesia (local anesthetic agents).
2. PRE-ANAESTHETIC EVALUATION
1 A thorough clinical examination of the patient is essential to establish the health status of the patient.
2. To detect the metabolic effects of the disease process for which he is undergoing the surgical procedure.
3. To detect any other existing disease in the patient, that he might be undetected so far.
