临床上静脉输液时,输注液体的温度均明显低于体温,而且温差较大,常常引起患者的血管痉挛、局部刺激性疼痛和静脉炎等不良反应。特别是冬季,对需要快速大量补液者,可能会造成较严重的全身反应。目前多采用热水袋在输液管外加热,以提高输注液体的温度,但效果差,无温度检测,并易引起局部皮肤的烫 Intravenous infusion, the infusion of liquid temperature were significantly lower than body temperature, and the temperature difference is larger, often caused by patients with vasospasm, local irritation pain and phlebitis and other adverse reactions. Especially in winter, those who need rapid rehydration may cause more serious systemic reactions. Currently more use of hot water bottle in the infusion tube heating to enhance the infusion of liquid temperature, but the effect is poor, no temperature detection and easy to cause local skin hot
