“…Fluid warming is an important method of heat conservation. 13 In our study, we found that core temperature in the test group decreased during the first 60 minutes, but was maintained over 36.5 C and increased to 36.9 C at the end of anesthesia, Figure 1. Changes of core temperature in the control group and test group.…”

“…Although it was shown that intravenous (IV) infusion of warmed fluids helped to prevent hypothermia during major abdominal surgery and ambulatory gynecological anesthesia [6,7], the Association of periOperative Registered Nurses (AORN) Recommended Practices Committee recommended that warmed infusion should be considered only if a large volume (ie, more than two L/hr) is administered [8]. Administration of a large volume of warm crystalloid (one L/15 min) reduced the incidence of shivering [9].…”

“…The infusion of cold or room temperature fluid, or blood can cause hypothermia in patients requiring administration of a large amount of fluid. Therefore, administration of pre-warmed fluid can be effective to restore a normal body core temperature (15)(16)(17). Peter et al suggested that there is no need to warm the infused fluid delivered at flow rates slower than 30 mL/min owing to the minimal change of core body temperature (7).…”

To evaluate the performance and safety of a newly developed blood warmer (ThermoSens), we tested its heating capability under various conditions using isotonic saline and hemolysis analysis with swine blood. The following two in vitro tests were performed: (i) To investigate the performance of the device, the inflow and outflow temperatures were measured at various flow rates (30, 50, and 100 mL/min) using cold (5°C) and room temperature (20°C) isotonic saline (0.9%). Several parameters were measured including the highest temperature of the outlet, the time required to reach the highest temperature, and the temperature of the intravenous line. (ii) To investigate the safety of the device, a hemolysis test was performed using swine blood. We obtained 320 mL of whole blood from swine and refrigerated the blood for 35 days at 3°C. In order to replicate the clinical situation, blood flow by gravity and pressure (300 mm Hg) was used. Before and after the heating test, blood samples were obtained and a comparison was made between these samples. Hemoglobin, hematocrit, lactate dehydrogenase, and plasma hemoglobin were used for red blood cell (RBC) damage analysis. The highest outlet temperatures obtained using flow rates of 30, 50, and 100 mL/min were 39.10 ± 0.59, 39.25 ± 0.69, and 37.63 ± 1.03°C, respectively, with cold saline, and 39.40 ± 0.40, 39.66 ± 0.36, and 39.49 ± 0.49°C, respectively, with room temperature saline. Hemolysis tests showed no significant changes in hemoglobin, hematocrit, lactate dehydrogenase, or plasma hemoglobin (P > 0.05) between before and after heating for both gravity and pressure blood flow. The ThermoSens blood warmer warms isotonic saline effectively, reaching temperatures up to 36°C under various conditions. Hemolysis tests showed no RBC damage. Therefore, the newly developed ThermoSens has good heating performance and is safe for RBC products.

Warming Intravenous Fluids Reduces Perioperative Hypothermia in Women Undergoing Ambulatory Gynecological Surgery

Abstract: Women who received i.v. fluid at body temperature had significantly higher core temperatures during and after outpatient gynecological surgery compared with women who received i.v. fluids at the temperature of the operating room.
