Step 1 - General Cleaning Instructions |
Wash the LMA™ airway in warm water with a mild detergent, or a dilute
sodium bicarbonate solution. Do not expose the valve to any cleaning
solution. A specific cleaner found to be compatible with LMA™ airway
use is Endozime® (Ruhof, Valley Stream, NY).
Do not expose the white plastic valve to any cleaning solution as it
may cause premature valve failure
WARNING: Do not expose the LMA™ airway to
germicides, disinfectants, or any agents containing glutaraldehyde,
phenol, iodine, or quaternary ammonium compounds. Such substances are
absorbed by the LMA™ airway materials, resulting in exposure of the
patient to potentially severe tissue burns and possible deterioration
of the LMA™ airway. Do not use an LMA™ airway that has been exposed to
any of these substances.
Cleaning Solutions NOT to Use with LMA™ Airways
| Glutaraldehyde or Ortho-phthalaldehyde |
Cidex®, Cidex OPA®, Wavicide® |
| Quaternary Ammonium |
A-33 Dry®, CIDA-FOAM™, Coverage® Plus, Power Keg®, T.B.Q® |
| Phenols |
Amerse®, Beaucoup®, LpH® se, Lysol® IC, Matar®, Vesta-Syde®, Vesphene II® se |
| Iodine |
Betadine® |
Note: Representative list only

Step 2 - Product Specific Cleaning Instructions |
When cleaning the LMA ProSeal™ with manual vent, the red plug should
be in the closed position (Figure A).
Clean the airway and drain tubes of the LMA ProSeal™ with a soft
bristle brush. Ensure the areas behind the Introducer strap and
under the internal drain tube are clean (Figure B).
The airway tubes of the LMA Fastrach™ and LMA Fastrach Endotracheal
Tube should also be carefully cleaned using a soft brush. Carefully
clean the area around the LMA Fastrach's™ epiglottic elevating bar
(EEB), taking care not to damage the bar (Figure C). Ensure the
whole interior of the metal tube is thoroughly cleaned.
The LMA Classic™ and LMA Flexible™ airway tubes may be cleaned by
carefully inserting a soft bristle brush through the aperture bars,
being careful not to damage them.
Note: LMA North America sells cleaning brushes for the LMA ProSeal™.
For all other LMA™ reusable airways LMA North America recommends a
½" cleaning brush made by Justman Brush Company - part # 1701, phone
(800) 800-6940.
|
Step 3 - Rinsing |
Thoroughly rinse the cuff and airway tube in warm flowing tap
water to remove cleaning residues.
Ensure the LMA™ airway is dry. If moisture is noted inthe valve or
inside the manual vent of the LMA™ ProSeal, tap against a towel to
remove excess moisture before autoclaving.
 |
Step 4 - Inspection |
Carefully inspect the LMA™ airway (and drain tube on the LMA
ProSeal™) to ensure that all visible foreign matter has been
removed. Repeat Steps 1, 2 and 3 as necessary.
WARNING: Failure to properly clean, rinse
and dry an LMA™ airway may result in retention of potentially
hazardous residue or inadequate sterilization.
 |
Step 5 - Sterilization Preparation |
Steam autoclaving is the only recommended method of
sterilization for LMA™ airways.
WARNING: Do not expose the LMA™ airway to ethylene oxide and
do not use a LMA device™ that has been exposed to ethylene
oxide.
Immediately prior to autoclaving the LMA Classic™, LMA
Flexible™, LMA Fastrach™ or LMA ProSeal™ without manual vent,
fully deflate the LMA™ airway cuff using a clean, dry syringe.
Remove syringe from valve before autoclaving to avoid damage
to valve. LMA Cuff-Deflators™ available from LMA North America
may be used to help achieve complete deflation.
CAUTION: Any air or moisture left in the cuff will expand
in the high temperature and low pressure environment of the
autoclave, causing irreparable damage to the cuff and/or
inflation pilot balloon.
For the LMA ProSeal with manual vent, it is not necessary to
deflate the cuff prior to steam autoclaving provided the red
vent plug is in the open position (Figure D). Note that after
autoclaving, the cuff of the LMA ProSeal™ with Manual Vent
will be inflated.
 |
Step 6 - Autoclaving |
Steam autoclave the LMA™ airway following the
manufacturer's recommendations and applicable institution
and industry guidelines for temperature and time.
Minimum Exposure times
All cycles 270° - 275° F (132° - 135° C)
| Autoclave |
Wrapped |
Unwrapped (Flash) |
| Gravity Displacement |
10-15 minutes |
10 minutes* |
| Prevacuum |
3 - 4 minutes |
4 minutes* |
*Mixed porous and nonporous items
Step 7 - Record Keeping
Record LMA™ airway use on record card. The record card is
provided with the purchase of every reusable LMA™ airway
The user should perform all the pre-use tests
before each use of the device. Failure of any test indicates
the device has passed its useful life and should be
replaced.
