    Abstract

    protocol describes how to use anesthesia machine with isoflurane to anesthetize a rat.

    Before start

    Handle rat beforehand to reduce stress* Bring rat from vivarium (or wherever it is kept) to surgery room in a clean cage

    Steps

    Setup

    1.

    Make sure you have a surgery room booked

    1.1.

    Some sort of table or surgical workbench to transfer rat to when fully anesthetized

    2.

    Grab isoflurane cart and/or supplies and bring it to the surgery room

    3.

    Place paper towels in the plastic container

    4.

    Make sure the tubing is tightly sealed together (if tape is needed add tape)

    4.1.

    Make sure all of the tubing is in the correct place and connected

    4.2.

    Make sure the valves are parallel with the tubing (the pink and orange tubing)

    5.

    Use larger thicker tape to secure white tubing down onto the surgery table (where you want it on the workbench)

    6.

    Snip open a little hole in a glove and place it over the tubing for the rat's mouth as a nose cone for anesthesia during surgical procedures

    7.

    Check isoflurane level (make sure it is between the minimum and maximum fill lines)

    7.1.

    If the isoflurane level is low then unscrew the cap and slowly add in the isoflurane

    Set isoflurane regulator on top-adjust dial as appropriate

    8.

    Use the black wrench to open the oxygen tank

    8.1.

    Turn to the right to open

    9.

    Look at the oxygen regulator and turn the green knob so the silver ball is in the middle of the 1 on the regulator.

    10.

    Place the rat in the plastic box and close the lid

    11.

    Adjust isoflurane dial as needed

    11.1.

    Start at 4 (if female)

    11.2.

    Start at 5 (if male), heavier animals usually need more isoflurane to become anesthetized

    12.

    Keep rat under for a few minutes or until the rat’s breathing slows down

    13.

    Take the rat out of the plastic container and place it onto the surgery table

    14.

    Do a toe pinch using forceps to make sure the animal does not feel any pain

    14.1.

    If the rat has a pain reflex or a jerk motion of the limb then place back into the plastic container and continue anesthesia

    14.2.

    If the rat has no pain reflex or jerk then continue

    15.

    Put the tubing that has the glove with the slit over the rat's mouth and nose to maintain anesthesia

    16.

    Then when the rat is fully anesthetized you can proceed with your surgery

    Turning off machine

    17.

    Turn off the isoflurane dial (back to 0)

    18.

    Take the black wrench to close the oxygen tank

    18.1.

    Turn to the left to close

    Troubleshooting

    19.

    Check to make sure there is no tubing loose/disconnected

    19.1.

    In case there is a leak

    19.2.

    Or if something is not working

    20.

    Adjust dial

    20.1.

    More or less isoflurane depending on how the rat is doing

    Cleanup and Transport

    21.

    Press the green oxygen flush button

    21.1.

    This clears out oxygen from the tubing

    22.

    Remove the paper towels and dispose of them

    23.

    Clean out the plastic box with paper towels and water only

    24.

    Return isoflurane machine and supplies to its storage place

    25.

    Place cage where the dirty cages go to be cleaned
