  • 手术室空气净化工程常用的杀菌方法!
    来源:http://www.hnsfk.com 浏览: 发布日期:2019-07-17
      手术室净化工程中常用的灭菌办法有:乳酸熏蒸消毒、甲醛、过氧乙酸熏蒸法、紫外线映照灭菌等。
      Sterilization methods commonly used in operating room purification project include lactic acid fumigation, formaldehyde, peracetic acid fumigation, ultraviolet radiation sterilization, etc.
      1、乳酸熏蒸消毒:消毒前空中喷洒少量清水,紧闭门窗。按每100m2空间用80%乳酸12ml,加等量水,倒入容器内,下置酒精灯加温,待药液蒸发完后将火熄灭,封锁30一60分钟,再翻开通风。适用于普通手术后的消毒。
      1. Lactic acid fumigation and disinfection: spray a small amount of water in the air before disinfection, and close doors and windows. According to each 100 m2 space with 80% lactic acid 12 ml, add equal amount of water, pour into the container, put alcohol lamp under the heating, until the liquid evaporation will extinguish the fire, blockade for 30 to 60 minutes, then turn on the ventilation. It is suitable for disinfection after general operation.
      2、甲醛、高锰酸钾消毒:按室内容积计算用量,40%甲醛(福尔马林)12mL/m3、高锰酸钾1g。房间相对湿度应在60%以上,室温在18℃以上。先将高锰酸钾置于容器内,再倒入甲醛溶液,即沸腾产生甲醛蒸气,封锁6—12小时,再开窗通风。适用于破伤风、气性坏疽等特殊感染手术后的消毒。
      2. Formaldehyde and potassium permanganate disinfection: According to indoor volume calculation, 40% formaldehyde (formalin) 12 mL/m3, potassium permanganate 1 g. The relative humidity of the room should be above 60%, and the room temperature should be above 18 C. First put potassium permanganate in the container, then pour into the formaldehyde solution, that is, boiling to produce formaldehyde vapor, blockade for 6-12 hours, and then open the window for ventilation. It is suitable for disinfection of tetanus, gas gangrene and other special infections after operation. Shandong Operating Room Purification Factory

      3、过氧乙酸熏蒸法:过氧乙酸3.75ml/m3,置于耐热容器中,加热蒸发,室温应超越18℃,密闭l一2小时。用于手术室空气消毒。手术室墙壁、门窗、空中、手术台的消毒常用化学消毒剂,如用2%一3%来苏儿(煤酚皂)溶液喷洒、擦洗,5%过氧乙酸2.5mL/m3喷雾,0.05%一0.1%新洁尔灭或洗必泰溶液喷雾、擦拭等。
      3. Peracetic acid fumigation method: peracetic acid 3.75ml/m3, placed in a heat-resistant container, heated and evaporated, room temperature should exceed 18 C, sealed for 1 to 2 hours. For air disinfection in operating room. Operation room, walls, doors and windows, air, operating table disinfection chemical disinfectants commonly used, such as 2% 1 3% to sue (phenol phenol) solution spraying, scrubbing, 5% peracetic acid 2.5mL/m3 spray, 0.05%, 0.1% new Jie Er or chlorhexidine solution spray, wipe and so on.
      4、紫外线映照灭菌:紫外线主要适用于空气的消毒,此外用于空调导管等物体外表的消毒。常用低压型汞灯,发射波长253.7nm的紫外线。消毒房间映照剂量,应依据室内容积和距灯管的远近计算,均匀映照剂量为1w/m3,映照时间为30一60分钟,每日2—3次,如30m3的房间,可用一支30W的紫外线灯,间隔光源60一100cm内灭菌效果较好。
      4. Ultraviolet radiation sterilization: Ultraviolet radiation is mainly suitable for air disinfection, in addition, it is used for surface disinfection of air-conditioning conduits and other objects. Ultraviolet radiation at 253.7 nm is commonly used in low-pressure mercury lamps. The irradiation dose of disinfection room should be calculated according to the indoor volume and distance from the lamp tube. The uniform irradiation dose is 1w/m3, the irradiation time is 30-60 minutes, 2-3 times a day. If the room is 30m3, a 30W ultraviolet lamp can be used, and the sterilization effect is better within 60-100cm of the interval light source.
