EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL
• Never insert or withdraw the endoscope under any of the
following conditions. Otherwise, patient injury, bleeding
and/or perforation can result.
− While the endo-therapy accessory extends from the distal
end of the endoscope.
− While the bending section is locked in position.
− Insertion or withdrawal with excessive force, or forcible
insert or withdrawal.
− While the image is magnified (when using the image
magnification function of the video system center
CV-180).
• 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Even when the endoscope has been withdrawn without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.
• If any of the following phenomena occur during an
examination, immediately stop the examination and withdraw
the endoscope from the patient as described in Section 5.2,
"Withdrawal of the endoscope with an abnormality" on
page 83.
