Abstract:

Objective To investigate the temperature change of enteral nutrition（EN） solution in pharynx and cardia during continuous feeding through a nasogastric tube（NGT） at normal environment temperature. Methods 42 patients with EN support were enrolled by the convenient sampling in the Intensive Care Department of a Level A tertiary hospital in Nanjing. The body temperature of the patients and the EN solution temperature in the NGT（in pharynx and cardia）were measured at different infusion rates（20 ml/h,50 ml/h,70 ml/h,100 ml/h,120 ml/h）. Results The temperature of pharyngeal nutrient solution corresponding to the EN solution infusion rates of 20ml/h,50ml/h,70ml/h,100ml/h,120ml/h were 37.35（36.2,38.2）℃,35.4（34.2,36.7）℃,（33.96±1.80）℃,32.75（30.88,33.63）℃,（31.46±1.55）℃. The corresponding temperature of cardiac nutrient solution were（37.51±0.86）℃,（37.37±0.88）℃,（37.30±0.85）℃,（37.13±0.86）℃,36.8（36.28,37.6）℃. When the infusion rate of the EN solution was less or equal to 100 ml/h,there was no significant difference between the EN solution temperature in the cardia and the body temperature of patients（P>0.05）.But when the infusion solution rate was≥50 ml/h,there were significant differences between the temperature of pharyngeal camp solution and the patient’s body temperature（P<0.05）. There was no significant difference among the EN solution temperature in the cardia and the temperature variation in different body temperature groups（36.0~37.0 ℃,37.1~38.0 ℃,38.1~39.0 ℃）（P>0.05）. Conclusion When the EN solution infusion rate was less or equal to 100ml/h and the body temperature ranges between 36.0~39.0 ℃,the EN solution temperature in cardia is close to the body temperature of the patient.
