SummaryThe fluid warming capabilities of the Bair Hugger, Hotline, Standard Ranger and Fluido devices were evaluated in the laboratory with gravity flow via a 14G cannula (1 m head of fluid) and with the fluid bag pressurised to 300 mmHg. The resulting flows (70-450 ml.min )1 ) were recorded. At a room temperature of 22°C, no device warmed the fluid to 37°C. However, the Standard Ranger with gravity flow and the Fluido with both gravity and pressurised flow achieved 35°C, whereas the Bair Hugger and Hotline with both gravity and pressurised flow, and the Standard Ranger with pressurised flow, achieved only 24-31°C. However, from the way delivered temperatures changed with flow, we calculated that all four devices would achieve close to 37°C at the flows specified by the manufacturers: 17, 83, 150 and 800 ml.min )1 for the Bair Hugger, Hotline, Standard Ranger and Fluido, respectively.

“…In addition, we did not warm the i.v. fluid, although 1 litre of unheated crystalloid is known to reduce the core temperature by 0.25e0.30 C. 7,21,35 However, because we restricted the fluid administration for thoracic surgery, 36e38 the bias would be minimized.…”

“…However, this effect was obtained at temperatures above 65°C [24]. Several studies had been conducted to test the heating ability of blood warmers [25][26][27][28]. In most cases, the results were below body temperature.…”
