Important Information Concerning Reusable Blood Warmer

By Margaret Snyder


Generally, when you donate blood and is not transfused to a patient at that time, it has to be stored in a refrigerator so as to enhance its life. Obvious, the temperature in a refrigerator is far much below the normal body blood temperature. It happens that this ice-cold fluid is transfused into the body system, conditions like hyperthermia, arrhythmias, and shock are likely to occur. That is why reusable blood warmer are used so as to provide the fluid with the necessary and appropriate temperature before being incorporated into the body.

These devices come in three different types in regard to the warming technique and technology used. The first type is the one that uses dry heat method. The other types include using a water bath and the other countercurrent. This can be done before transfusion or during the process which is referred to as in-line warming. The device, however, is made with a technology that prevents any loss of heat but it does not provide heat retaining methods.

Once you raise the temperature to the one required which is thirty-seven degree Celsius, you transfuse the fluid into your body since when you don't do it, it will naturally cool down to where the temperature was initially. Additionally, it can provide heat without interfering with the living cells like WBC and RBC.

In most cases, these devices are used during mass transfer of blood or to patients who require more than fifty percent of the body blood volume. They are also used when the volumes to be administered requires urgency or need to be done rapidly. This is because, if a large amount is transfused when cold the mentioned cases are likely to occur due to temperature lowering beyond the recommended range. They are also used when the patients receiving the blood have cold agglutinins.

When a patient is likely to suffer cold agglutinins, these devices become very beneficial is eliminating this negative effect. On the other hand, elderly, neonates and pediatric patients should be accorded special considerations before this can be done to them. Also, people suffering cardiac and chronic disorders should also be treated in the same manner.

These devices are advantageous since the patients can acquire the body temperature which is necessary and the side effects such as the cold or low temperature get eradicated. Moreover, you do not have to dispose of the device together with the storage and bags. You can use again and again. You only need to fix the device in a body, or a bag in case of countercurrent and then switch it on and start operating.

However, it has certain limitations such as failure or temperature maintain technology. It can only prevent loss of heat by active warming but does not have a way in which the patient can be kept warm. That is why other methods like warming, water, blankets as well as pads can be used as another way or remedy to conditions like hypothermia.

Infusing warm fluids in the bloodstream does not necessarily mean that the body temperature will rise. They are just remedial ways of providing warmth.
