含氯制剂消毒干预层流手术间连台手术自净时间的探讨

Research of chlorinated praeparatum sterilization on intervention of self-cleaning time of consecutive operations in laminar flow operating room

目的探讨含氯制剂消毒干预层流手术间连台手术自净时间的效果。方法随机选择百级层流手术间无菌切口手术(Ⅰ类手术)60例和万级层流手术间可能污染手术(Ⅱ类手术)60例。其中在百级手术间将含氯制剂消毒干预后再闭门层流自净6、12 min后的手术各20例分别设为1组、2组,第3组为百级手术间采用关闭门常规使用层流空气自净消毒方法的20例;在万级手术间将含氯制剂消毒干预后再闭门层流自净10、15 min后的手术各20例分别设为4组、5组,第6组为万级手术间采用关闭门常规使用层流空气自净消毒方法的20例。1、2组及4、5组均用浓度为500 mg/L的含氯制剂在手术结束时做物表擦拭、空气喷雾消毒等。观察比较6组的菌落数、细菌生长率、切口愈合率等。结果同类层流手术间、同类手术切口患者的菌落数、细菌生长率、切口愈合率等相比差异无统计学意义(P>0.05)。结论使用含氯制剂对层流手术室连台手术手术间消毒进行干预,可减少连台手术的等待时间,具有一定的实用意义。

Objective To explore effect of chlorinated praeparatum sterilization on intervention of self-cleaning time of consecutive operations in laminar flow operating room.Methods 60 cases with germ-free incision operations were carried out in class 100 laminar flow operating room,which including 20 cases with 6 minutes of self-cleaning mode after intervention of chlorinated praeparatum sterilization（Group 1） and 20 cases with 12 minutes of self-cleaning mode after intervention of chlorinated praeparatum sterilization（Group 2） respectively,and another 20 cases with primary self-cleaning mode（Group 3） after the former operation.60 cases with possible contamination of incision operation were carried out in class 10 000 laminar flow operating room,which including 20 cases with 10 minutes of self-cleaning mode after intervention of chlorinated praeparatum sterilization（Group 4） and 20 cases with 15 minutes of self-cleaning mode after intervention of chlorinated praeparatum sterilization（Group 5） respectively,and another 20 cases with primary self-cleaning mode（Group 6） after the former operation.500 mg/L of chlorinated praeparatum was used to clean instrument and disinfect air at the end of operations in Group 1,2,4 and 5.Bacterial colonies,growth rate of bacteria and healing rate of wound were observed and compared between 6 groups.Results There were no significant differences of bacterial colonies,growth rate of bacteria and healing rate of wound between patients with same type of operating room or same incision of operation（P〈0.05）.Conclusion Implementation of chlorinated praeparatum for sterilization intervention of consecutive operations in laminar flow operating room can shorten the latency times of consecutive operations.
