Résumé
Objective:To analyze the application value of PAD (Presentation-Assimilation-Discussion) class and case teaching combined with brainstorming in the practice teaching of nursing students in the department of cardiovascular surgery.Methods:A total of 81 undergraduate nursing students who practiced in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Air Force Medical University from June 2019 to April 2020 were selected as the research objects. They were randomly divided into the control group ( n=40, brainstorming teaching) and the observation group ( n=41, PAD class combined with case teaching). After one month of intervention, the teaching effect on the two groups of nursing students were evaluated through the nursing students' clinical communication ability scale, Chinese version of self-assessment of clinical reflection and reasoning (SACRR), and competency inventory for registered nurse (CIRN). And the teaching quality was assessed by the clinical nursing teacher teaching behavior assessment scale. SPSS 22.0 was used for t-test. Results:The scores of each dimension and total scores of clinical communication ability scale, Chinese version SACRR and CIRN of nursing students in the observation group were higher than those in the control group ( P<0.05). The scores of nursing teaching behavior evaluation of clinical teachers in the observation group were higher than those in the control group ( P<0.05). Conclusion:The combination of PAD class and case teaching with brainstorming can improve the clinical communication ability of nursing students in cardiovascular surgery practice, help to promote the transformation of their clinical thinking ability, improve their core competences, and play an important role in improving the teaching quality.

Objective:To explore the effect of scenario simulation combined with "finding fault" teaching method on prevention and control of nosocomial infection training in standardized residency training of cardiovascular surgery.Methods:A total of 31 residents trained in the Department of Cardiovascular Surgery, The First Affiliated Hospital of Naval Medical University from April 2018 to March 2019 were selected as the control group, and another 31 residents trained from April 2019 to March 2020 were selected as the study group. All subjects were required to receive nosocomial infection prevention and control training. The control group was given conventional teaching method, while the study group was given scenario simulation combined with "finding fault" teaching method, all of which were taught for 1 month. The theoretical and operational assessment results of nosocomial infection prevention and control after teaching, the clinical core competence related to nosocomial infection prevention and control after teaching, and the recognition rate of teaching mode were compared between the two groups. SPSS 25.0 was used for t test and chi-square test. Results:The scores of theoretical assessment [(91.29±6.64) vs. (86.73±6.02)] and operational assessment [(90.32±6.80) vs. (83.51±7.43)] of nosocomial infection prevention and control after teaching in the study group were higher than those in the control group, with statistical differences ( P<0.05). The scores of clinical core competence in learning initiative, doctor-patient communication, problem thinking and problem solving of nosocomial infection prevention and control knowledge after teaching in the study group were higher than those in the control group, with statistical differences ( P<0.05). The recognition rates of innovation, interest, effectiveness and practicability of the teaching mode in the study group were 83.87%, 96.77%, 90.32% and 93.55% respectively, while those in the control group were 61.29%, 58.06%, 67.74% and 74.19% respectively, which were higher in the study group than in the control group, with statistically significant differences ( P<0.05). Conclusion:In the training of prevention and control of nosocomial infection for standardized residency training in the department of cardiovascular surgery, scenario simulation combined with "fault finding" teaching method can improve the theoretical and practical examination results of the residents, enhance their clinical core competence related to nosocomial infection prevention and control, and reach a higher recognition rate of the teaching mode.
Résumé
Se realizó un estudio descriptivo y transversal de 73 pacientes con fibrilación auricular de nueva aparición en las primeras 72 horas del periodo posoperatorio de revascularización coronaria, intervenidos quirúrgicamente en el Servicio de Cirugía Cardiovascular del Hospital Provincial Docente Clinicoquirúrgico "Saturnino Lora Torres" de Santiago de Cuba, desde enero de 2010 hasta igual período de 2013. En la serie, los mayores de 60 años fueron los más afectados (71,2%), con un aumento en la frecuencia a medida que avanzó la edad. Primaron el sexo masculino (74,3 %) y el hábito de fumar (86,0 %). Entre los factores más notables figuraron: antecedentes de hipertensión arterial, fracción de eyección ventricular izquierda por debajo de 55,0 %, revascularización incompleta y uso del bypass de apoyo. Aunque esta arritmia se relacionó con otras complicaciones posoperatorias, el bajo gasto cardiaco y los accidentes vasculares encefálicos predominaron en esta investigación.
A descriptive and cross-sectional study was carried out in 73 patients with new-onset atrial fibrillation in the first 72 hours of the postoperative period of coronary bypass surgery, surgically treated at the Cardiovascular Surgery Department of "Saturnino Lora Torres" Provincial Teaching Clinical Surgical Hospital in Santiago de Cuba, from January 2010 to the same month of 2013. In the series those older than 60 years were the most affected (71.2%), with an increase in frequency as age advanced. Males (74.3%) and smoking habit (86.0%) prevailed. Among the most remarkable factors were history of hypertension, left ventricular ejection fraction below 55.0%, incomplete revascularization and use of the bypass support. Although this arrhythmia was related to other postoperative complications, low cardiac output and strokes prevailed in this study.
