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.
They are classified in three categories following the technology or technique used to provide heat. They include dry heat that uses hot air, water bath devices that use hot water as a heating medium and lastly the countercurrent machines which use electric power to provide heating. The process of raising the temperature is usually done in the cabinets before being transfused into the patient or in line during the transfusion activity.
This means that once the temperatures have been raised to the required which is in most cases is 37 degrees Celsius, this fluid has to be transfused because when not done, it will definitely cool down to the initial temperature. It also contains the ability to provide heat without tampering with living cells such as RBC and WBC.
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.
The devices are supposed to be in operation mode prior to the exercise so as to provide temperature rise in a gradual and systematic way not in a random way that can affect the cells. When properly utilized, negative effects associated with cold temperature will not be experienced. The devices, on the other hand, are not disposed after a single use as they are reused. They are also convenient devices more the countercurrent that requires auto start-stop to keep the required temperature.
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.
Additionally, it does not mean that the body temperature will rise when you infuse the warm fluids in your bloodstream. They are just therapeutic options for offering warmth.
