A mobile laminar airflow unit to reduce air bacterial contamination at surgical area in a conventionally ventilated operating theatre
The aim of this study was to evaluate the efficacy of a mobile laminar airflow (LAF) unit in reducing bacterial contamination at the surgical area in an operating theatre supplied with turbulent air ventilation. Bacterial sedimentation was evaluated during 76 clean urological laparotomies; in 34 of these, a mobile LAF unit was added. During each operation, settle plates were placed at four points in the operating theatre (one at the patient area and three at the perimeter), a nitrocellulose membrane was placed on the instrument table and an additional membrane near the wound. During four operations, particle counting was performed to detect particles ≥0.5 μm. Mean bacterial sedimentation on the nitrocellulose membrane on the instrument table was 2730 cfu/m2/h under standard ventilation conditions, whereas it decreased significantly to a mean of 305 cfu/m2/h when the LAF unit was used, i.e. within the suggested limit for ultraclean operating theatres (P = 0.0001). The membrane near the wound showed a bacterial sedimentation of 4031 cfu/m2/h without the LAF unit and 1608 cfu/m2/h with the unit (P = 0.0001). Particle counts also showed a reduction when the LAF unit was used. No significant difference was found at the four points in the operating theatre between samplings performed with, and without, the LAF unit. Use of a mobile LAF unit with turbulent air ventilation can reduce bacterial contamination at the surgical area in high-risk operations (e.g. prosthesis implant).
一种能在普通通风手术室的手术区域减少空气污染的移动空气层流装置
这个研究的目的是评价一种移动空气层流装置在空气呈乱流状态的手术室的手术区域中减少微生物污染的效果。分析76台清洁泌尿外科手术的空气沉降菌，其中34台手术使用了移动空气层流装置。在每台手术期间，采样平皿被放置在手术室的四个点（1个在病人附近，三个周边区），一张纤维采样纸放在操作台，另一张放在靠近病人手术切口位置。在4台手术中测试尘埃粒子计数器检测≥0.5 μm的尘埃粒子。在普通通风条件下，纤维采样纸上的平均沉降菌为2730 cfu/m2/h，而在有移动层流装置的情况下明显的减少为305 cfu/m2/h即接近超净手术室的标准（两者比较P = 0.0001）。没有移动层流装置情况下接近切口的沉降菌为4031 cfu/m2/h，而有移动层流装置的为1608 cfu/m2/h（P = 0.0001）。在使用移动层流装置的情况下，尘埃粒子也明显减少。在分别使用和不使用移动层流装置的情况下，4个手术室空气样本结果在位置上没有明显差别。乱流手术室内在高危手术期间（如移植手术）手术区域使用移动层流装置能减少微生物污染。
