Purpose: To explore the effect of fine management combined with man-machine fixation mode in reducing the attrition rate of laparoscopic instruments.
Methods: This is a non-randomized, concurrent controlled study, from December 1, 2023, to May 1, 2024, the use of 4 laparoscopic instruments in the operating room which belongs to shanghai first maternity and infant hospital was analyzed. The instruments were divided into two groups, and the control group was managed by conventional methods. The observation group implemented with fine management combined with man-machine fixed mode. We used instrument attrition rate and physician satisfaction as outcome indicators.
Results: In this study, four laparoscopic instruments were investigated, and a total of 858 cases were used, including 429 cases in the control group (machine 1, machine 2) and 429 cases in the observation group (machine 3, machine 4). After the implementation of refined management combined with man-machine fixed mode, the observation group had significantly lower attrition rate and failure rate of laparoscopic instruments than the control group, including insufficient instrument preparation (p = 0.000), unstable light source (p = 0.012), air leakage (p = 0.000), screen color distortion (p = 0.040), and blurred visual field (p = 0.000). The satisfaction of doctors in the observation group was significantly higher than that in the control group, including preoperative preparation, process cooperation, operation proficiency, trouble solving ability, instrument debugging ability, communication and service attitude (p < 0.01).
Conclusion: The use of fine management combined with man-machine fixed mode in the management of laparoscopic instruments in the operating room can effectively reduce the incidence of instrument attrition rate, improve the efficiency of surgery, and the economic benefit of the hospital, which is worthy of popularization and application.
