智能手机模拟导航用于脑出血微创清除术的效果及学习曲线分析OA

Objective:To explore the effect and learning curve of smart phone simulation navigation in minimally invasive re-moval of cerebral hemorrhage.Methods:116 patients with cerebral hemorrhage admitted to Wenzhou Hospital of Integrat-ed Traditional Chinese and Western Medicine from March 2023 to March 2025 were selected as the research object,and were divided into two groups by computer random number table method.The control group(58 cases)was treated with traditional CT navigation minimally invasive surgery for cerebral hemorrhage,and the observation group(58 cases)was treated with smart phone simulation navigation minimally invasive surgery for cerebral hemorrhage.Compare the main outcome and the secondary outcome of the two groups,and draw the learning curve of smart phone simulation navigation by using CUSUM regression model.58 patients in the observation group were divided into learning group and mastering group with the vertex of the learning curve of operation time as the boundary,and the operation effect was compared.Re-sults:The operation time,drainage tube removal time,ICU stay and hospitalization time in the observation group were shorter than those in the control group,and the intraoperative blood loss and positioning error were smaller than those in the control group,and the hematoma clearance rate was higher than that in the control group(P<0.05).The inflection point of learning curve based on operation time was the 15th case.Taking the 15th case as the boundary,the observation group was divided into study group(cases 1～15)and master group(cases 16～58).The operation time of study group was(98.65±24.26)min,which was longer than that of master group(84.25±20.65)min(P<0.05).Conclusion:The effect of smart phone simulation navigation in minimally invasive removal of cerebral hemorrhage is satisfactory,and the cumulative number of surgical cases required to cross the learning curve to master the stage is about 15 cases.
