Abstract:
Objective:To evaluate the effects of 3D printing and mixed reality (MR) in teaching ultrasound-guided spinal puncture for scoliosis and to provide new approaches for enhancing educational outcomes in this field.Methods:Twenty anesthesiologists with no experience of spine ultrasound were selected from the Department of Anesthesiology at Peking Union Medical College Hospital and received training in ultrasound-guided spinal puncture in March 2024. They were assigned to the MR glasses+3D printing group or 3D printing group, with 10 participants in each group. The trainees in the MR glasses+3D printing group observed the spine model with the HoloLens 2 glasses and then conducted ultrasound-guided spinal puncture on the 3D-printed spine model. The trainees in the 3D printing group directly conducted ultrasound-guided spinal puncture on the 3D-printed spine model. The teaching effects were evaluated with objective puncture indicators (success rate and puncture time) and questionnaire survey. Data were analyzed using the independent samples t-test or chi-square test in SPSS 27.0. Results:The puncture time was shorter in the MR glasses+3D printing group compared with the 3D printing group [(165.90±69.91) s vs. (239.30±80.30) s, t=2.18, P=0.043]. The success rate of spinal puncture was 90.00% (9/10) in the MR glasses+3D printing group and 80.00% (8/10) in the 3D printing group, with no statistically significant difference ( P>0.999). The satisfaction [(4.70±0.48) vs. (4.80±0.42), t=0.49, P=0.628] and recommendation [(4.80±0.42) vs. (4.90±0.32), t=0.60, P=0.556] of the training method showed insignificant differences between the MR glasses+3D printing group and the 3D printing group. Conclusions:The combination of 3D printing with MR technology can provide trainees with a safe and repeatable high-fidelity simulation training system for ultrasound-guided spinal puncture. The system can improve the confidence and interest of trainees in ultrasound-guided spinal puncture techniques and enhance training efficiency. This combination demonstrates advantages and potential in training for spinal ultrasound and ultrasound-guided spinal puncture.
