PREMEDICATION



6. THE PRE-OPERATIVE PREPARATIONS
The stomach, rectum and bladder should be empty before taking the
patient to the theatre.
I
It is customary to have a patient on empty stomach and a low enema given the night before.

6.1 PRE-ANAESTHETIC MEDICATION
A patient is usually apprehensive, therefore, may spend a
sleepless night prior to the operation.
It i$ desirable to sedate the patient with a hypnotic, or a
tranquilliser (barbiturates or valium).

6.2 AN HOUR PRIOR TO SURGERY
The patient receives;
* Injection of Pethidine 50 mg.
* Phenargen 25 mg., and injection Atroprine 1/100th of grain
intramuscularly.
This produces basal narcosis which is the ideal state for the
patient prior to the induction of anaesthesia.
The choice of the type of anaesthesia will depend upon the
surgical procedure to be undertaken, and the result of the pre-
anaesthetic check in which the health status has been defined.
