5.3 GENERAL ANAESTHESIA
The inhalation agent for anesthesia, is in most instances delivered
through an endotracheal tube
Short term barbiturates (pentothol) injected, into a vein intravenously.
This is referred to as induction, and enables the introduction
of the endotracheal tube with the help of direct laryngoscope
The tube is then connected with an anesthesia machine
5.3.1 TECHNIQUE
The dose of anesthetic to be given to any patient by inhalation
cannot be calculated based on milligrams of anesthetic per
kilogram body weight.
* In addition, there is a problem of maintaining sufficient
ventilation.
* Both these objectives are obtained by frequent clinical
examination of the patient so as to ensure sufficient level
of anaesthesia and adequate ventilation.
* The mixture of the anesthetic agent, and oxygen is adjusted
to provide sufficient anesthesia, without causing excess
depression of the central nervous system, by observing the
effect on reflexes.
* The ideal state to be maintained is a plane of anesthesia
in the 3rd state.
The ideal plane will depend upon the surgical procedure to
be performed.
* In all events, 4th stage, a stage of over dosage is to be
avoided.
These reflexes are listed, and the stages indicated, in the
Table.
