129361-177 Operator Manual Summary of Warnings and Cautions

A Word from STERIS

Corporation on the

Warming of Solutions

STERIS encourages the users of all our products to follow recommended

clinical practices to insure safe and effective use of medical products. Clinical

practice guidelines are documents that have been developed systematically

to help healthcare practitioners and patients make informed decisions about

the management of health conditions. Recommended practices provide

guidelines for the implementation of safe care to patients and assist in the

identification of potential hazards in the practice setting.

In accordance with this philosophy, we offer the following information on

warming solutions.

Your STERIS Warming Cabinet is capable of warming fluids, however the user

should ALWAYS follow the specific instructions of the manufacturer of the

solution prior to warming any fluid.

In accordance with your facility protocol and recommended practices, in order

to reduce possible patient injury, always verify the temperature of any heated

fluid prior to its use or administration.

The recommended practice for warming IV and irrigation fluids in a

warming cabinet:

• Before warming IV and irrigation fluids in the warming cabinet, check with

the manufacturer of the solution or fluid for their specific recommendation.

The manufacturer’s directions will vary, depending on the composition of

the bottle material, the solution and the manufacturing process.

• Irrigation/infusion solutions should be warmed or cooled to the temperature

appropriate for the surgical need.

• Infused fluids should be heated or cooled in devices intended for that

purpose.

• Manufacturer’s written recommendations for storage, heating, and proper

use of all skin prep solutions products should be followed. If the

manufacturer has not provided specific instructions on heating, the

manufacturer of the solution should be contacted for clarification before

any prepping solution is warmed.

• Microwaves and autoclaves should not be used as warming devices.

WARNING - BURN HAZARD:

DO NOT USE LIQUIDS ON -

OR INJECT IN - LIVING TIS-

SUE unless actual liquid tem-

perature has been measured

and is acceptable. Tempera-

ture of warming cabinet may be

hotter than the displayed cham-

ber air temperature. For patient

safety, in accordance with good

medical practice, always check

liquid temperature prior to us-

ing.

c. If the OVERTEMPERATURE INDICATING light and audible alarm remain,

turn the temperature control knob OFF and allow more cooling time with

Figure 3-3. Loading Techniques

(See Figure 3-3)

1. STERIS suggests that users standardize loading, unloading, cool down,

temperature checking, and come-up times, then post in an obvious

location.

2. Temperature of solutions is the responsibility of the surgeon and is a

matter of individual professional judgement and practice. In general,

temperature of solutions should not exceed 105°F (40°C) and should

always be checked prior to use.

3. In all cases, solutions should be checked before using for safe patient

temperature with a sterile-certified thermometer or equivalent reliable

means. Solution bags should be checked prior to use by pouring and

checking a sampling of contents.

4. Never overload the cabinet(s) or stack items beyond recommended

limits (see Figure 3-3).

5. All loads should be allowed to stabilize at the set temperature:

SOLUTIONS: In bottles - Approx. 8 Hrs.

In bags - Approx. 12 Hrs.

BLANKETS: - Approx. 8 Hrs.

6. Bagged solutions will heat more effectively if placed on shelves pro-

vided. Stacking increases the heating time.

7. If it is necessary to remove only part of a load from the cabinet(s), then

a FIFO (First In, First Out) routine is recommended.

8. Blankets can generally be felt by hand by a qualified nurse for patient

safe temperature.

9. Bottles should be spaced from each other for most effective uniform

heating.
