Precautions for intratracheal use in the animal.
Use of all Penn-Century devices for intratracheal
applications is essentially a form of intubation. Familiarity with intubation procedures and anesthetized
animal prep is a prerequisite for use of the devices. Typically, the anesthetized animal is held securely on
an intubation platform with its mouth open and tongue pushed aside. For optimal lung deposition, the
intratracheal portion of the MicroSprayer® Aerosolizer must be inserted so the tip reaches just above the
carina. When using the any Penn-Century intratracheal aerosol device – whether liquid or dry powder,
the user must push the plunger of the syringe fast and with force to aerosolize the liquid inside.
Therefore, the user must exercise care and attention to
minimize any forward motion of the hand
while pushing quickly and firmly on the plunger, to prevent trauma or injury to the animal. Added
illumination from a Penn-Century Small Animal Laryngoscope can be helpful in correction positioning.
