LF-TP/DP/GP OPERATION MANUAL
• The shape and size of the nasal cavity and its suitability for
transnasal insertion may vary from patient to patient. No
endoscope, including this one, can always be inserted
transnasally with all patients. Before proceeding, always be
sure to confirm that transnasal insertion is possible with the
patient. Otherwise, operator and/or patient injury can result or
the endoscope could become lodged and be difficult to
withdraw.
• 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Even when the endoscope has been withdrawn without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. 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.
