RESUMO
Objective:To explore the value of "conceive, design, implement, and operation" (CDIO) combined with cluster training mode in clinical teaching of cardiopulmonary resuscitation (CPR).Methods:A total of 108 interns of General Hospital of Southern Theater Command from January 2019 to November 2020 were included in the study, and they were randomly divided into control group ( n=54) and observation group ( n=54). The control group used the cluster training mode for CPR teaching, and the observation group used CDIO combined with the cluster training mode for CPR teaching. The theoretical performance, operation performance, comprehensive ability, chest compression quality and CPR time of the two groups of interns were compared, and the scores of post competency and satisfaction of the two groups of interns were evaluated. SPSS 22.0 was used for t test and chi-square test. Results:The scores of theory, operation and comprehensive ability in the observation group were higher than those in the control group. Compared with those before training, the compression depth, compression frequency and chest rebound rate of the observation group were higher than those of the control group. The observation group found that the patients' unconscious judgment of pulse free time, the time from the occurrence of ventricular fibrillation to the start of automated external defibrillator (AED), and the time to complete AED were lower than those in the control group. The five dimensions of practical ability, critical thinking ability, coordination ability, career development ability, psychological characteristics and the total score of post competency in the observation group were higher than those in the control group ( P < 0.05). The satisfaction of the observation group with the teaching teacher, practice content, practice form and practice effect was higher than that of the control group ( P<0.05). Conclusion:The application of CDIO combined with cluster training in clinical CPR teaching can improve the interns' theoretical performance, operational performance and comprehensive ability, improve the quality of external chest compression and CPR time, make the interns have good communication ability and post competency, and finally improve the interns' satisfaction.
RESUMO
Four adults of Fasciola hepatica were found from the bile ducts of a patient diagnosed as biliary calculi during a surgi-cal operation. We investigated retrospectively the infection source and concluded that the patient may be infected by eating raw or half-cooked Zizania latifolia,an aquatic plant,which was contaminated with metacercariae of F. hepatica.
