目的探讨高原高寒野战条件下运血箱用于血液储存的温控方式及效果。方法采用预充电制冷、低温冻结和自然温度冻结的蓄冷剂制冷、预充电加蓄冷剂制冷4种方式控温,监测自然环境及恒温条件下储血箱内温度及控温时间,检查血液外观和输血效果观察。结果自然环境下(-5～17℃),预充电制冷方式运血箱控温时间41 h,环境最低温时,箱内温度低于2℃;2种蓄冷剂制冷及预充电加蓄冷剂组合制冷方式温控时间分别为68、13和89 h。恒温条件(14～18℃)下,4种方式控温时间分别为13 h(预充电)、16 h(低温冻结蓄冷剂)、10 h(自然冻结蓄冷剂)、22 h(预充电+蓄冷剂)。结论高海拔地区野外作业时,大量冻结高效蓄冷剂用于野战运血箱储存血液,具有较好的控温效果。
Objective To investigate the temperature control method and effect of blood donation for blood storage in the plateau and alpine field. Methods Pre-charge refrigeration, low-temperature freezing and freezing natural cooling agent cooling, pre-charging plus cooling agent cooling 4 ways to control temperature, monitoring the natural environment and constant temperature storage tank temperature and temperature control time, check the blood appearance and Transfusion effect observation. Results Under the natural environment (-5 ~ 17 ℃), the preconditioning cooling method was used to control the temperature for 41 h, and the lowest temperature in the environment was less than 2 ℃. Two kinds of cooling and pre-charging combined with coolant Refrigeration temperature control time were 68,13 and 89 h. Under the condition of constant temperature (14-18 ℃), the temperature control time of the four methods were 13 h (pre-charge), 16 h (low temperature frozen coolant), 10 h (natural frozen coolant), 22 h Agent). Conclusion In the field work at high altitude, a large number of frozen high-efficiency cooling agent is used to store blood in the field blood transfusion tank, which has good temperature control effect.
