What is HotDog Patient Warming?
The Most Advanced Temperature Management System Ever

The HotDog Patient Warming System helps maintain patient normothermia during surgical procedures. The Controller sends low-voltage direct current to air-free Patient Warming Blankets and Mattresses. This creates safe, uniform warmth for the patient for many surgical positions.

HotDog is the only Patient Warming System that can effectively warm from above and below at the same time.
HotDog Delivers the ABCs of Patient Warming

Air-Free
HotDog utilizes a unique conductive fabric called ThermAssure® which emits no waste heat. Forced-air warming systems contaminate the air of the sterile field. Waste heat carries particles from the ground to the surgical site.

Better Warming
Warm from above and below the patient at the same time. HotDog is the only patient warming technology that utilizes both blankets and mattresses. These give it tremendous versatility and effectiveness for many procedures.

Cost Effective
Implement HotDog with no up-front costs and immediate cost savings. Decrease your cost of care. Normothermic patients have better outcomes. This leads to shorter hospital stays and faster operating room turnover rates.
What are Users Saying?
Air-Free, Conductive Warming

The compact HotDog Temperature Management Controller delivers low-voltage direct current to Blankets and Mattresses with precise temperature control.
Blankets can be set to 37°C–43°C.
Mattresses can be set to 35°C–40°C.

It is then converted into safe, even heat by the patented ThermAssure® conductive fabric.
The lightweight, flexible heater fabric produces uniform and precise heat. The smart Controller manages the heat with an advanced sensor system.
The heater is sealed in an antimicrobial, non-porous shell. It’s 100% easily cleanable and available in a variety of warming Blankets and Mattresses.

HotDog heats Mattresses with uniform warmth across the entire surface. Safe temperatures are 35°C–40°C (95°F–104°F).

Frequently Asked Questions
How is HotDog safer for orthopedic surgeries?
Air-free HotDog patient warming is safer for surgeries involving implanted foreign materials—such as orthopedic and cardiac surgery—because there is no waste heat disrupting the sterile field with contaminants. Rising waste heat from forced-air warming contaminates the sterile surgical field above the table with dirty air from the floor by generating convection currents. There is an increasing body of peer-reviewed evidence published on this issue. (Research)
Are the blankets difficult to clean?
Click for the full Cleaning Guidelines. The cleaning process takes 30 seconds or less. The blankets can be cleaned in the OR by wiping with a low- to intermediate-level disinfectant—whatever is currently used to wipe surfaces like the OR table. The blankets are designed for easy cleaning: the outer shell is non-porous and heat-sealed to eliminate crevices. The CDC says noncritical items (only come in contact with intact skin) like HotDog blankets are safe and present virtually no risk of cross-contamination. Also, HotDog cables are much easier to wipe down than a forced-air warming corrugated hose. For more information see this video on cleaning:
Can the HotDog system be used in x-rays?
Yes. The heater fabric is completely radiolucent. However, each warming blanket and mattress has parallel buss bars that run along the long edge of the warming device. These can be seen on x-ray. In addition, the area around the sensor is also radio-opaque. See the Underbody Warming brochure (M106C) for a diagram of the radiolucent areas of a warming mattress. If x-raying will be done (through the chest cavity, for example) then the mattress should be positioned such that the imaging area does not contain the sensor or buss bar.
Can HotDog mattresses be used in conjunction with electrosurgical grounding pads?
The U5XX series combines both patient warming and electrosurgical grounding, so there is no need for an additional return electrode pad.
However, when using the U1XX series, placing mattress underneath the grounding pad will diminish the thermal effects of the HotDog mattress. If the warming mattress is on top of the grounding pad, the surgeon may see a diminished effect at the active electrode. There is usually an indication from the grounding pad controller if there is not a good ground. Consult with the grounding pad manufacturer for more specifics.
The most successful approach is to stagger the mattress and the grounding pad. Make sure the HotDog mattress’s sensor is in contact with the patient’s torso for best warming results.
Does HotDog offer any warming options for cases using steep Trendelenburg?
Yes. Procedures where the patient is positioned in steep Trendelenburg historically result in high rates of hypothermia due to the small surface area available for warming. The HotDog Waffle-Grip Trendelenburg positioning accessory effectively prevents the patient from sliding on the table while still providing warmth under the patient.
How does forced-air warming (FAW) impact surgical infections?
Published research shows a 74% reduction in deep joint infections after discontinuing the use of forced-air patient warming. Ventilation disruption was associated with a significant increase in deep joint infections for FAW versus patient groups in which forced-air warming was discontinued and patients were warmed with conductive fabric blankets and mattresses. (N=1,437 cases; 2-5 years period P=0.028) Click here for an abstract of the study. (JBJS study abstract)
Is there a greater risk of cross-contamination with reusable HotDog blankets than with disposable FAW?
No. Consult Cleaning and Safety Information for more detail. HotDog products are considered “non-critical items,” meaning they only come in contact with intact skin. According to the CDC, “Virtually no risk has been documented for transmission of infectious agents to patients through noncritical items…” Another thing to consider is that the risk of contamination may actually be greater with FAW. FAW is only partially disposable. The blower and hose are used with thousands of different patients, sometimes moving from one OR to another. One published study showed that 92% of FAW blowers are contaminated with bacteria, and 58% internally generated and emitted germ-sized particles (Albrecht, AJIC, 2011). The contamination is significant because high-velocity air blows across the germ colonies. The contaminated hot air vents under the drapes, mixes with “dirty” floor air and rises into the sterile field.
Pre- and post-op warming is important for our patients. How is this possible with HotDog blankets?
HotDog blankets are ideally suited for pre- and post-op warming. Lower or full-body blankets can provide active warmth for as low as $1/patient. It’s a much less expensive option than disposable forced-air warming gowns or piles of warmed cotton blankets. (Savings)
How can you warm a patient if they are prepped from head-to-toe and there is no place to position a blanket, such as in open heart surgery or for burns?
HotDog offers an underbody warming mattress that can be placed on the OR table and used to warm patients from below. Underbody warming is great at preventing heat loss and maintaining patients’ core temperature. Effective rewarming requires blankets, which can be used in conjunction with a mattress.
