Effect Analysis of WeChat Platform Combined with PBL Teaching Method for Standardized Training of Residents in Anesthesiology Department

Objective: To explore and analyze the effect of the WeChat platform combined with the PBL teaching method in the standardized training of anesthesia residents. Methods: 120 anesthesiology residents from January 2018 to the end of December 2019 were selected, and divided into a control group and an observation group of 60 each according to the time sequence of admission. The control group adopted the conventional teaching mode, and the observation group adopted the WeChat platform combined PBL teaching method. The scores of theoretical knowledge and anesthesia skills operation after training, the scores of the teaching interest survey, and the satisfaction with the teaching mode between the two groups were compared. Results: The scores of theoretical knowledge and anesthesia skills operation in the observation group were significantly higher than those in the control group, and the indicators of teaching interest in the observation group were also higher than those in the control group. The differences were statistically significant (P < 0.05). The satisfaction degree of the observation group was significantly higher than that of the control group, and the difference was also statistically significant (P < 0.05). Conclusion: The WeChat platform combined with the PBL teaching method is beneficial to improve the training effect of anesthesiology residents, stimulating autonomous learning ability, ensuring the effective practice of theoretical knowledge, and promoting them to move towards a higher standard of anesthesia skills.

Effects of dexmedetomidine combined with ultrasound-guided nerve block on hemodynamics, immune function and cortisol levels in patients undergoing inguinal surgery

Objective:To investigate the effect of dexmedetomidine combined with ultrasound guided nerve block on the hemodynamics, immune function and cortisol level in the patients undergoing inguinal surgery.Methods:A total of 120 patients who underwent unilateral inguinal surgery in our hospital were randomly divided into control group and observation group, 60 cases in each group. The control group was induced by intravenous anesthesia with sufentanil. The observation group was given dexmedetomidine combined with ultrasound guided ilioinguinal/iliac hypogastric nerve block. Hemodynamics, immune function and cortisol levels were compared between the two groups before and after anesthesia induction. Results:After anesthesia, in surgical incision and recovery time, the levels of HR in the two groups were significantly lower than that before the anesthesia, and the levels of HR in the observation group were significantly lower than that in the control group. After anesthesia, in surgical incision and recovery time, the levels of CD3+, CD4+ and CD4+/CD8+ in the control group were significantly lower than that of the group before anesthesia. After anesthesia, the levels of CD3+, CD4+ and CD4+/CD8+ in the observation group were significantly lower than that of the group before anesthesia. In surgical incision and recovery time, there was no significant difference in the levels of CD3+, CD4+ and CD4+/CD8+ in the observation group before anesthesia. After anesthesia, in surgical incision and recovery time, the levels of CD3+, CD4+ and CD4+/CD8+ in the observation group were significantly higher than that of the control group. The levels of serum PI3K, ET -1, CRP and cortisol of the two groups were significantly higher than those before anesthesia, and the levels of PI3K, ET -1, CRP and cortisol in the serum of the patients in the observation group were significantly lower than those in the control group.Conclusion: The effect of dexmedetomidin combined with ultrasound guided nerve block anesthesia on the patients with inguinal surgery can effectively maintain the hemodynamic stability of the patients and have less influence on the immune function and the stress response. The security is higher.
