手术帽虽经过高压灭菌,但在进入手术室前和术中,易被污染。在手术过程中,尤其是较深、视野较小的手术,由于手术视野不甚满意,手术帽极易相互碰撞摩擦。为证明手术中,参加手术人员手术帽相互碰撞摩擦,是否会造成切口的污染,我们对一次性手术帽和棉布手术帽“碰帽”和“不碰帽”后污染情况进行了两组试验对照观察。1 试验方法与结果 本试验在手术室进行过程中,用空气沉降法采 Although the surgical cap after autoclaving, but before entering the operating room and surgery, easily contaminated. In the course of surgery, especially deep, less vision surgery, due to unsatisfactory surgical field of vision, surgical caps easily collide with each other friction. In order to prove that the surgical staff involved in surgical caps collide with each other and will cause incision contamination, we conducted two sets of experimental controls on the contamination of disposable surgical caps and cotton surgical caps after “touching the caps” and “not touching the caps” Observed. A test method and results The test in the operating room during the process, using air-settlement method mining
