Abstract：Objective To study the value of 3D printed surgical guide plate and mixed reality technology in the puncture and drainage of complex hypertensive intracerebral hemorrhage.Methods A total of 110 patients with complex hypertensive intracerebral hemorrhage who were admitted into our hospital from April 2021 to August 2022 were selected as subjects and further randomly divided into two groups,namely the research group(55 cases)and the control group(55 cases).Both groups underwent the puncture and drainage surgery in our hospital.To distinguish between them,the research group adopted the 3D printed surgical guide plate+mixed reality technology while the control group received puncture with CT-guided localization.In addition,preoperative preparation,length of surgery and hospital stay,medical expenses,total effective rate,both high and low resection viscosity of whole blood,neurological deficit score(NDS),the generic quality of life inventory-74(GQOLI-74)score,hematoma clearance rate,puncture accuracy,complications,etc.Results Length of preoperative preparation,surgery and hospital stay of the study group was shorter than that of the control group,and the medical cost of the study group was lower than that of the control group(P<0.05).Total effective rates of the study group and control group were 98.18%and 83.64%,the former being higher than the latter.Additionally,in both groups,before treatment,high and low resection viscosity of whole blood showed insignificant difference(P>0.05).By contrast,3 and 7d after treatment,above two identical indicators upregulated and displayed significant difference statistically(P<0.05).Furthermore,expression levels of the two indexes were lower in the study group than in the control group.Prior to therapy,NDS and GQOLI-74 score in both groups were not significantly different(P>0.05).After treatment,NDS of the study group was lower than that of the control group while GQOLI-74 score was the opposite,difference between being statistically significant(P<0.05).Besides,the hematoma clearance rate and puncture accuracy of the study group were higher than that of the control group while incidence rate was the opposite,difference between being statistically significant(P<0.05).Conclusion 3D printed surgical guide plate+mixed reality technology manifested more ideal effect in puncture and drainage,which could shorten the length of hospital stay,reduce the impact on blood rheology and improve neuronal function.Moreover,puncture accuracy and hematoma clearance rate were upregulated accompanied with less complications in this method,contributing to apparently enhanced life quality of patients.
