4.1

Precautions

WARNING
• To guard against dangerous chemicals and potentially infectious material during
the procedure, wear personal protective equipment, such as eyewear, face mask,
moisture-resistant clothing, and chemical-resistant gloves that fit properly and are
long enough so that your skin is not exposed.
• The temperature of the distal end of the endoscope may exceed 41°C (106°F) and
reach 50°C (122°F) due to intense endoscopic illumination. Surface temperatures
over 41°C (106°F) may cause mucosal burns. Always maintain a suitable distance
necessary for adequate viewing while using the minimum level of illumination for
the minimum amount of time. Do not use close stationary viewing or leave the distal
end of the endoscope close to the mucous membrane for a long time without
necessity.
• Whenever possible, do not leave the endoscope illuminated before and/or after an
examination. Continued illumination will cause the distal end of the endoscope to
become hot and could cause operator and/or patient burns.
• Never insert or withdraw the endoscope under any of the following conditions.
Patient injury, bleeding, and/or perforation can result.
− While the bending section is locked in position.
− Insertion or withdrawal with excessive force.
• 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, bleeding, and/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when the endoscope has been withdrawn without bleeding, do not allow the patient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.
