Abstract:
Objective To explore the applicative effects of visualization techniques in clinical education of anesthesia resident standardizing training. Methods A total of 50 physicians who were receiv-ing resident standardizing training were recruited. They were randomly divided into the control group and visualization group with 25 residents each. The control group was taught to perform intratracheal intubation, using traditional laryngoscope and to perform indwelling catheter via femoral vein puncture, using traditional"blind puncture"method. The visualization group was taught to perform intratracheal intubation, using visual laryngoscope and to perform indwelling catheter via femoral vein puncture through ultrasound guidance method. Both groups conducted training on anthropomorphic dummy and patients. The operating time, success rates and incidence of complication were recorded. Learning curves were also graphed. GraphPad Prism 6 was used for statistical analysis. Data compared between groups were analyzed by t test and χ2 test. Results The time of intratracheal intubating on anthropomorphic dummy in control group was (45.1± 16.3) s and that in visualization group was (32.8 ±13.4) s (P<0.05). The learning curve decreased more quickly in visualization group. The time of intratracheal intubating on patients in control group was (44.1± 10.1) s and that in visualization group was (36.7±9.8) s (P<0.05). Rates of complications such as oral bleeding and postoperative sore throat was lower in visualization group (P<0.05). The femoral catheterization time of control group was (11.7±2.4) min and that of visualization group was (10.6±2.5) min (P<0.05). The success rate of control group was 76.8％ and that of visualization group was 89.6％ (P<0.05). Furthermore, the rate of inadvertent arterial puncture was lower in visualization group (P<0.05), and the learning curve decreased more quickly in visualization group. Conclusion Visualization techniques can provide an effec-tive teaching method for anesthesia resident standardizing training and has broad prospects in application.
