1. Correct use of laminar flow room: the operating table shall be arranged as close as possible to the appropriate place of laminar flow ceiling net, and all operation steps shall be as close as possible to the corresponding place of laminar flow ceiling net to prevent sterile package at the return air outlet. Infection operation shall be arranged in the operation room with negative pressure laminar flow as far as possible, and special disinfection shall be carried out in case of special operation. The operation shall be carried out according to the three channel line: the entrance and exit of medical personnel, the entrance and exit of patients and the exit of dirt are the access lines designed for the laminar flow operating room.
2、保持清洁效果：采用手术室净化空调系统应该持续使用24 h，培养空气细菌合格次数打2次后投入使用。手术前半小时将层流空调系统打开，接台手术需相隔15 min，保证空调系统持续运转。在手术前期要采用500 mg/L的含氯消毒液湿式将有关器材的血迹灰尘清理干净。对于初效、中效过滤器更换周期为6个月/次，过滤器1～2年/1次。回风口1周/1次，这样才能保证使用器材的清洁效果。
2. Maintain cleaning effect: the operating room purification air conditioning system shall be used for 24 hours for the first time, and the air bacteria shall be cultured for 2 times before being put into use. Turn on the laminar flow air conditioning system half an hour before the operation, and the next operation needs to be separated by 15 minutes to ensure the continuous operation of the air conditioning system. In the early stage of operation, 500 mg / L chlorine containing disinfectant shall be used to wet clean the blood and dust of relevant equipment. The replacement cycle of primary and medium efficiency filters is 6 months / time, and that of high efficiency filters is 1 ~ 2 years / time. Return air outlet once a week, so as to ensure the cleaning effect of equipment.
3. Equipment protection: in the early stage of operation, it is usually necessary to control the indoor temperature at an unsteady value and ensure that the air conditioner operates for 24 hours, or turn it on half an hour before operation according to its own situation. Clean the primary filter screen and air outlet once a week to avoid pollution. The replacement of medium efficiency and high efficiency filter screen shall be carried out according to the air culture.
After the implementation of operating room purification, we should pay attention to the overall energy consumption and use optimization ways to save energy. Strengthening the management of laminar flow operation room mainly depends on all-round nursing quality control in the whole process of operation. Operating room purification is only a means, and the degree of sterility is the guarantee for the continuous and efficient operation of various operations. Strengthening the management of operating room purification and strengthening the concept of sterility is still the top priority of operating room work. Only by closely combining the two can we obtain good social and economic benefits.
