EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
−
Transnasal insertion is accompanied by the risk of
inflammation of the nasal cavity. If this happens, the nasal
passage will be constricted, making it more difficult to
withdraw the endoscope. In this case, do not use force to
withdraw the endoscope because patient injury such as
bleeding or perforation may result.
−
Transnasal insertion is accompanied by the risk of
bleeding in the nasal cavity. Be sure to be prepared to
deal with any bleeding. When withdrawing the
endoscope, observe the inside of the nasal cavity to
ensure that there is no bleeding. Even when the
endoscope has been withdrawn without bleeding, do not
allow the patient to blow his or her nose strongly because
this could cause it to start bleeding.
−
Before transnasal insertion, apply the appropriate
pretreatment and lubrication to the patient to enlarge the
nasal cavity. Otherwise, operator and/or patient injury can
result or the endoscope could become lodged and be
difficult to withdraw. When applying a pretreatment agent
through a tube, insert the tube into the same path as the
path planned for the endoscope insertion. Otherwise, the
treatment will have no effect. The effects of the
pretreatment agent and lubricant will decrease the longer
the procedure lasts. Apply the pretreatment agent or
lubricant as required during the procedure
–
for example,
when withdrawal seems to be difficult.
−
Transnasal insertion of the endoscope should be
performed carefully. If resistance to insertion is felt, or the
patient reports pain, stop insertion immediately.
Otherwise, operator and/or patient injury can result or the
endoscope could become lodged and be difficult to
withdraw.
−
If it becomes impossible to withdraw the transnasally
inserted endoscope, pull its distal end out of the mouth,
cut the flexible tube using wire cutters, and after ensuring
that the cut section will not injure the body cavity or nasal
cavity of the patient, withdraw the endoscope carefully.
Therefore, always prepare wire cutters in advance.
• Never perform angulation control forcibly or abruptly. Never
forcefully pull, twist or rotate the angulated bending section.
Patient injury, bleeding and/or perforation can result. It may
also become impossible to straighten the bending section
during an examination.
