The PDCA cycle has the effect of increasing the effective use rate of disposable items in the operating room. Methods From January to May 2012, 446 general surgery and hepatobiliary surgery operations without PDCA cycle management were performed, and 9362 disposable sterile items were set as the pre-implementation group.

 From June to November 2012, 501 surgical and hepatobiliary surgeries under PDCA cycle management were implemented, and 1,1973 pieces of disposable surgical items were set as the post-implementation group. Compare the effective use rate of disposable sterile items before and after PDCA implementation and the satisfaction of surgeons to nurses in the operating room. Results The effective use rate of disposable sterile items before and after the implementation of PDCA and the satisfaction of surgeons to nurses in the operating room were both P<0.05, the difference was statistically significant. The effect after implementation was significantly higher than before implementation. Conclusion PDCA circulation management of disposable sterile items in operating room can effectively improve the utilization rate of disposable items, reduce waste and save resources. The operating room is an important medical resource of the hospital. Through effective process optimization and the use of anesthesia recovery room, its operating efficiency has been continuously improved, but it still cannot meet the growing medical service needs of patients and clinical departments, and there are still overutilization and underutilization of the operating room. Happening. Manual surgical resource scheduling improves the utilization efficiency of surgical resources to a certain extent, and the surgical resource scheduling optimized by the mathematical collaboration of the computer system can make up for the lack of manual scheduling, achieve system resource matching and dynamic real-time optimization, effectively reduce the hospitalization time of surgical patients and improve The efficiency of surgical resource utilization. Understand the air pollution of bacteria in different time periods during multiple operations in the clean operating room. Methods: Two hundred-level clean operating rooms with an area of 40 m2 were selected, and 144 Class I incision operations were performed continuously for 48 times under the same temperature and humidity environment. The two operating rooms are group A and group B respectively. After each operation in group A, the operating room is routinely cleaned, and the next operation is performed after 15 minutes of static self-cleaning; the operating room in group B is routinely cleaned after the operation, and the next Surgery.

During the operation of the two groups, the frequency and range of movement of personnel, opening and closing doors, moving instruments, and sorting cloth items were controlled. The "five-point method" was used to arrange bacterial culture medium sampling in the operating room at 9 time points when the first, second, and third surgical patients were cut on the day of the two operating rooms, 60 minutes before the beginning of the operation, and 10 minutes before the end.
