When blood is kept refrigerated in storage until it is used in transfusion, it is a common practice in the medical field these days to use warming. A reusable blood warmer is recommended in various situations such as this. The medical needs specific to the individual patient, along with outside factors, should be taken in consideration by the medical staff when making decisions about administering this red liquid.
Use of warming devices for the transfusions is appropriate in cases of resuscitation when rapid transfusions are needed. A patient might fall into hypothermia from administration of fluid that is too cold. Medical professionals are urged to avoid this situation at all times.
When the volume to be administered is higher than 25%, it is advisable to use warming devices prior to transfusion. In such situations it is very probable that even more blood units may be needed. Therefore the units might need to be administered quickly.
Cases when patients have cold agglutinins also require transfusions with warmed blood. The medical staff should also consider treatment with special care in situations involving neonates. Patients that have high risk of heart problems, children, or elderly patients should also be taken care of with the same special attention or even more when they need transfusions.
In situations that require this red liquid to be warmed, medical staff should only use professional equipment. Medical warming devices normally have an attached visible thermometer. They also need to be equipped with a functioning audible alarm that can alert the staff in case the temperature goes beyond a value higher than 41 degree celsius.
Several advantages are offered by these devices. Besides warming this red liquid, they can also transfer IV fluids, making them practical in multi-purposed cases. Temperatures of 38 degree celsius can be easily reached with a flow rate between ~2-150 mL/min, and a heater with automatic adjustment is provided when needed.
Maintenance is mandatory every 12 months, and it must be carefully monitored. If malfunctions occur, the devices can become extremely dangerous. If the temperature of this vital fluid exceeds 41 degree celsius, the medical staff should immediately inform the blood bank.
Theatres, ASCU, maternal-fetal medicine, nurseries, 6B nurseries and 6D PICU are all locations where these medical warming devices can be found. When the medical staff uses these devices, they have to write down the operating temperature. Again, blood transfusions are recommended only by using these devices.
Professional warming devices can process all sorts of standard infusions. A backup battery is included, and the devices are portable and light-weight. Completing setup takes about 45 seconds, and they are to be disposed when the transfusion is over.
Nowadays, the medical staff can use disposable fluid warmers (blood and IV fluids), all thanks to technology which has evolved immensely in the medical industry. Thermiflow fluid warmers, the most recently developed disposable devices, are self-powered medical machines. They are activated automatically when exposed to the atmospheric air, and can offer changes in temperature of 10 degree celsius with a 40 mL/min flow rate.
