Surgical Care

Complex problems require novel solutions. 

Perioperative hypothermia is a common but largely preventable problem with serious implications for patients, surgeons, and hospitals. Costly surgical complications, prolonged recovery time, higher risk of surgical site infection, and increased blood loss are all negative outcomes associated with poor management of patient temperature. Belmont’s advanced patient temperature management solutions have been designed with the modern OR in mind, because we know that providing complex clinical care requires a team of not just people, but also specialized equipment designed to deliver predictable outcomes.

Maintaining Normothermia Is Mission-critical

Everything about the OR leads to cold patients—the room temperature, the exposed patient, the administration of cold fluid, and, of course, the anesthesia itself. A rapid initial decrease in temperature is noted in the first half hour following anesthesia administration, with core temperature dropping by about 1 to 1.5°C in the first hour.3 Additionally, administration of 1 liter of room-temperature saline can lead to a drop in core temperature by 0.25°C.4 Furthermore, even mild hypothermia contributes significantly to patient care costs and needs to be prevented.5 A dip of only 1.9°C in core temperature was found to triple the incidence of surgical wound infection and increase the duration of hospitalization by 20% following colon resection.6

In response, modern ORs employ a variety of methods to help maintain patient normothermia during surgery, by utilizing warming devices throughout the entire perioperative continuum, pre-op to post-op, and by administering all fluids through a dedicated IV warming device.

How We Help

Your Patients’ Fast Track to the PACU

Used by top cardiac centers, Allon® reliably maintains consistent patient temperature during surgical procedures using uniquely designed body-shaped ThermoWrap® garments that provide ideal body surface coverage and surgical access. Unlike Forced Air Warming (FAW), Allon’s level of precision in normothermia maintenance reduces the need for post-operative warming, and because normothermic patients can be extubated sooner, Allon helps fast-track patients to the PACU.7,8

Performance You Can Trust

The Belmont® Rapid Infuser RI-2 is an essential and potentially life-saving tool frequently utilized in cardiac and organ transplant procedures where there is a high risk of significant blood loss. The system’s multiple resource-saving capabilities enable surgical teams to remain focused on the patient throughout the procedure. Integrated patient safety features help limit the risk of adverse events associated with massive blood transfusions, while highly efficient electromagnetic heating technology provides consistent, normothermic fluid on demand.


“The Rapid Infuser has truly changed our practice here and represents a significant advance in our ability to care for patients requiring significant intraoperative fluid and blood resuscitation.”

— Department Chair, LA


“The use of a conductive, warm water-circulating device resulted in significantly

higher core intraoperative temperatures on arrival to the intensive care unit compared with the underbody convective forced-air warming device.”
