Objective:To evaluate the application value of simplified augmented reality (AR) technique in the location of puncture point before drainage of supratentorial hemorrhage in the elderly.Methods:One hundred and sixty-three senile patients with supratentorial cerebral hemorrhage (amount of bleeding: 30-60 mL) treated by hematoma drainage from February 2018 to February 2020 were chosen in our study; 85 patients (observation group) were treated with AR technique assisted drainage, and 78 patients (control group) accepted drainage assisted by virtual reality (VR) technique (3D slicer software) combined with AR technique (Sina software). The differences of preoperative location time, accuracy rate of catheter placement, sufficient drainage rate of hematoma within 72 h of surgery, postoperative pulmonary infection rate, postoperative Intensive Care Unit staying time, and favorable prognosis rate were compared between the two groups.Results:The accuracy of the catheter placement (95.3% vs. 94.9%), sufficient drainage rate of hematoma within 72 h of surgery (96.5% vs. 96.2%), postoperative pulmonary infection rate (21.2% vs. 19.2%), postoperative Intensive Care Unit staying time ([75.5±16.7] h vs. [81.5±19.5] h), favorable prognosis rate (75.3% vs. 70.5%) between the observation group and control group showed no significant differences ( P>0.05), but the preoperative location time in the observation group was significantly shorter than that in the control group ([12.2±6.5] min vs. [37.5±11.3] min, P<0.05). Conclusion:On the basis of no significant difference in the accuracy and therapeutic effect of catheter placement, drainage assisted by simplified AR technique is more convenient and faster than that by VR combined with AR technique.
