摘　　要：目的：探讨0.9%氯化钠溶液在42℃保温箱中的保存期限及成本分析。方法选择80瓶0.9%氯化钠溶液作为研究对象,使用统计软件SAS 9.2随机分成对照组和保温组,每组各40瓶,对照组置于层流洁净手术室室温下,保温组置于42℃保温箱中。各组分别于5个时间点（实验开始后3 d、1周、2周、3周、4周）各取8瓶检测其细菌培养的菌落数和pH值的变化。在前期实验的基础上随后选取12个手术间,随机分为A组和B组,各6个手术间。 A组由保温箱A供应温0.9%氯化钠溶液,保存期限3 d；B组由保温箱B供应温0.9%氯化钠溶液,保存期限4周。结果两组0.9%氯化钠溶液细菌培养均为阴性。对照组5个时间点pH值分别为（6.35±0.29）,（6.32±0.04）,（6.23±0.20）,（6.29±0.35）,（6.36±0.32）；保温组5个时间点pH值分别为（6.37±0.42）,（6.31±0.11）,（6.39±0.21）,（6.42±0.45）,（6.60±0.32）,两组同一时间点pH值差异无统计学意义（t值分别为0.1108,0.2417,1.5610,0.6450,2.1110；P 〉0.05）。 A 组0.9%氯化钠溶液消耗量为（2761±118）瓶,成本为（11042±470）元,B组消耗量为（1466±205）瓶,成本为（5862±820）元,两组比较差异均有统计学意义（t=13.41；P〈0.01）。结论0.9%氯化钠溶液在42℃保温箱中的保存期限可延长至4周,检测指标符合药典要求,可降低其用量并节约成本。Objective To explore the storage life and cost analysis of 0. 9% sodium chloride solution in 42℃ conveuse. Methods A total of 80 bottles of 0. 9% sodium chloride solution had been selected as research sampling, and the SAS 9. 2 were used to randomly divide them into control group （put sampling in clean laminar flow operation room at room temperature） and experimental group （ put in 42℃ conveuse） on average. Eight bottles of each group were took out for the number of colony examination after germiculture and the change of pH value （ at the beginning of 3 days, 1 week, 2 weeks, 3 weeks and 4 weeks experiment） . Basis on the previous experiment, we selected 12 operating room and randomly divided into A group and B group on average. A conveuse provided warm 0. 9% sodium chloride solution, which had three days storage life in A group, but B conveuse offered warm 0. 9% sodium chloride solution of 4 weeks storage life. Results The results of germiculture were negative in both group. The 5 time point of pH values were （6. 35 ± 0. 29）, （6. 32 ± 0. 04）, （6. 23 ± 0. 20）, （6. 29 ± 0. 35）, （6. 36 ± 0. 32） at the control group, while these of experimental group were （6.37 ±0.42）, （6.31 ±0.11）, （6.39 ±0.21）, （6.42 ±0.45）, （6.60 ±0.32）and at the same time point the pH value of two groups had no statistical significance （t=0. 110 8, 0. 241 7, 1. 561 0, 0. 645 0, 2. 111 0;P〉0. 05）. Compared with A group-consumed （2 761 ± 118） bottles, cost （11 042 ± 470） Yuan, B group consumed （1 466 ± 205） bottles and cost （5 862 ± 820） Yuan with statistical significance between two groups （t=13.41;P〈0.01）.Conclusions Thepreservationof0.9% sodiumchloridesolutionin42℃ conveusecan be maintained 4 weeks and reduced cost by the decreasing the number of usage, and the testing norm is accord with the acquirement of pharmacopeia.
