目的监测分析某三甲医院风冷式冰箱的冷藏室不同位置温度,为病区护士正确使用风冷式冰箱提供依据.方法? 2017年6—7月,采用便利抽样选取浙江省某三甲医院的3台风冷式冰箱,对每台冰箱的冷藏室3层的前、后、左、右、中及储物盒、送风口、回风口、面板温度、冰箱的实时温度等23个不同位置采点的温度进行监测、对比、分析.结果?(1)风冷式冰箱冷藏室箱体3层各层前、后、左、右温度比较,各层左、右温度,上层的前、后温度比较,差异无统计学意义(P＞0.05);中层、下层的前、后温度比较,差异有统计学意义(P＜0.01) ;(2)冰箱门和冰箱体中间监测点比较,差异有统计学意义(P＜0.01); (3)送风口、回风口温度比较,差异有统计学意义(P＜0.01);(4)冰箱箱内检测到的实时温度与体中层温度比较,差异有统计学意义(P＜0.01).结论? 护士掌握风冷式冰箱冷藏室温度特点、不同空间位置的温度差、修改温度后温度变化的时间差,并正确使用,才能使风冷式冰箱满足用于病区药品保管温度的要求.

Objective? To monitor and analyze the temperature of different positions in the cold closet of an air-cooled refrigerator in a Class Ⅲ Grade A hospital, and provide guidance for nurses in the ward to use air-cooled refrigerators properly. Methods? Totally 3 air-cooled refrigerators from a ClassⅢ Grade A hospital in Zhejiang Province were selected by convenient sampling during June to July 2017. Temperature of 23 different positions from 3 compartments of the cold closet of each refrigerator were monitored, compared, and analyzed, covering the front, back, left, right, middle, storage box, air supply outlet, return air inlet, panel, and real- time temperature meter of the refrigerator, etc. Results?(1) The temperature of the front, back, left and right compartment of the air-cooled refrigerator was compared, temperature of the left and right of the middle and lower compartment was compared, temperature of the front and the back of the upper compartment was compared, all difference of the above showed no statistical significance (P＞ 0.05). The difference between the front and the back of the middle and lower compartment showed statistical significance (P＜0.01). (2) The difference between the refrigerator door and the monitoring point in the middle of the refrigerator was statistically significant (P＜0.01). (3)The temperature difference between the air supply outlet and the return air inlet was statistically significant (P＜0.01). (4)The real-time temperature detected in the refrigerator box was statistically different from the temperature detected in the middle of the refrigerator body (P＜0.01). Conclusions? Nurses should master the cold closet temperature features of air-cooled refrigerators, the temperature difference between different spatial positions, and the time difference of temperature changes after temperature modification and use the refrigerators correctly, so as to meet the temperature requirements for medicine storage in the wards.
