Source: A Manual Of Peroral Endoscopy And Laryngeal Surgery
Strict aseptic technic must be observed in all endoscopic
procedures. The operator, first assistant, and instrument nurse must
use the same precautions as to hand sterilization and sterile gowns as
would be exercised in any surgical operation. The operator and first
assistant should wear masks and sterile gloves. The patient is
instructed to cleanse the mouth thoroughly with the tooth brush and a
20 per cent alcohol mouth wash. Any dental defects should, if time
permit, as in a course of repeated treatments, be remedied by the
dental surgeon. When placed on the table with neck bare and the
shoulders unhampered by clothing, the patient is covered with a
sterile sheet and the head is enfolded in a sterile towel. The face is
wiped with 70 per cent alcohol.
It is to be remembered that while the patient is relatively immune to
the bacteria he himself harbors, the implantation of different strains
of perhaps the same type of organisms may prove virulent to him.
Furthermore the transference of lues, tuberculosis, diphtheria,
pneumonia, erysipelas and other infective diseases would be inevitable
if sterile precautions were not taken.
All of the tubes and forceps are sterilized by boiling. The
light-carriers and lamps may be sterilized by immersion in 95 per cent
alcohol or by prolonged exposure to formaldehyde gas. Continuous
sterilization by keeping them put away in a metal box with formalin
pastilles or other source of formaldehyde gas is an ideal method.
Knives and scissors are immersed in 95 per cent alcohol, and the
rubber covered conducting cords are wiped with the same solution.
