为保障洁净手术室使用的安全性和有效性,需定期进行悬浮粒子和沉降菌的检测,为控制和消除手术室感染提供科学依据。悬浮粒子和沉降菌的分别按照标准[1]和标准[2]采样,布点和评价均按照标准[3]的要求。本文通过检测8家医院共69间手术室的沉降菌和悬浮粒子,分析得出:69间手术室的沉降菌全都符合标准,合格率为100%,67间手术室的悬浮粒子符合标准,合格率为97.1%,差异有统计学意义(P<0.01)。由此可知,高级别手术室的悬浮粒子较难达标;沉降菌浓度与悬浮粒子呈一定的正相关。
In order to ensure the safety and effectiveness of the clean operating room, it is necessary to carry out the detection of suspended particles and sedimentation bacteria on a regular basis to provide a scientific basis for controlling and eliminating the infection in the operating room. The suspended particles and sedimentation bacteria were sampled according to standard [1] and standard [2] respectively, and their distribution and evaluation were in accordance with standard [3]. In this paper, the detection of sedimentation in 69 operating rooms in eight hospitals and suspended particles, analysis: 69 operating room settling bacteria are all in line with the standard pass rate of 100%, 67 operating room suspended particles meet the standards, qualified The rate was 97.1%, the difference was statistically significant (P <0.01). It can be seen, high-level operating room of the suspended particles is more difficult to achieve standards; sedimentation bacteria concentration and suspended particles showed a certain positive correlation.
