Last winter, an intravenous fluid was attempted in a low-temperature environment with an outside temperature of -10 C or lower, and the infusion was frozen in a tube.In this study, we investigated how the intravenous fluid temperature decreased in a low temperature environment. In this report, we performed experiments in a laboratory kept at 0 C or less. intravenous fluid was performed for 10 minutes using saline and Ringer's acetate solution heated to 40 C, and the change of the intravenous fluid temperature was measured. Then, the temperature of the intravenous fluid flowing in the tube was measured every minute with a thermocouple inserted inside the tube.As a result, it was found that the intravenous fluid temperature decreased with time and approached the outside temperature 10 minutes later. The intravenous fluid was cooled in the tube so it was considered necessary to keep the intravenous fluid tube warm.
