摘要
目的 从经济学角度探讨手术薄膜的使用价值。方法 选取手术病人 10 0例 ,其中使用手术薄膜 5 0例为实验组 ,未使用手术薄膜 5 0例为对照组。行术前、术后皮肤采样 ,细菌培养及成本效益分析。结果 术前 2组均未发现细菌生长 ,术后 2组细菌阳性率差异无统计学意义 (P >0 .0 5 )。手术薄膜的使用没有达到医院感染管理成本应用的目标 ,即细菌阳性率降至最低的效果。
Objective To discuss the use value of operative membrane from the aspect of economics. Method 100 patients were chosen: 50 patients with operative membrane as the experiment group, another 50 without operative membrane as the comparison group. Skin sampling, bacteria culture and cost analysis were carried out before and after operation. Results No bacteria were found in two groups before operation. After operation no significant difference was shown between the two groups in positive rate of bacteria (P>0.05). Operative membrane didn't accomplish the original purpose of saving costs in avoiding hospitalized infection, namely decreasing the positive rate of bacteria to the least. Conclusion Operative membrane not only has no significant protective effects on incision but also increase the costs of hospital.
