Evaluation of the Educational Value of Low-Cost Training Model for Emergency Cricothyrotomy.

BACKGROUND: In this study, we aimed to evaluate the educational value and students' satisfaction with the hand-made low-cost cricothyrotomy simulation model. MATERIALS AND METHODS: A low-cost and hand-made model and a high-fidelity model were used to assess the students. The students' knowledge and satisfaction were evaluated using a 10-item checklist and a satisfaction questionnaire, respectively. Medical interns in the present study participated in a two-hour briefing and debriefing session held in the Clinical Skills Training Center by an emergency attending doctor. RESULTS: Based on the results of data analysis, no significant differences were found between the two groups in terms of gender, age, the month of internship, and last semester's grade (P = .628, .356, .847, and .421, respectively). We also found no significant differences between our groups in terms of the median score of each item in the assessment checklist (P = .838, .736, .805, .172, .439, .823, .243, .950, .812, and .756, respectively). The study groups had no significant difference in the median total scores of the checklist as well (P = .504). Regarding the students' satisfaction, our results showed that interns evaluated their experience of the model as positive (median scores of 4 and 5 out of 5). They also gave the hand-made model a median score of 7 in comparison with the high-fidelity model and 8 out of 10 for its usability. CONCLUSION: The study results showed that a low-cost model could be as effective as an expensive high-fidelity model for teaching the necessary knowledge of cricothyrotomy techniques to medical trainees.

Opioid Dependency and Myocardial Infarction: A Systematic Review and Meta-Analysis.

BACKGROUND: Coronary artery disease is a major cause of morbidity and mortality worldwide. A major health concern in the developing countries is opioid addiction, which has controversial cardiovascular side effects. We aimed to investigate whether Myocardial Infarction (MI) and its risk factors are associated with morphine dependency in the Iranian population. METHODS: Electronic databases, including PubMed, Medline, Scopus, SID, Element, and Magiran were searched to find published articles including the keywords morphine, coronary artery disease, hypertension, hyperlipidemia, and diabetes mellitus. RESULTS: Twelve studies involving 25,800 people were included in this systematic review and metaanalysis. Morphine dependency was significantly associated with MI with an adjusted odds ratio (AOR) of 2.28 (95%CI=1.26-4.11). It neither has significant associations with hypertension (AOR=0.952; 95%CI=0.696-1.301) nor diabetes (AOR=0.895; 95%CI=0.644-1.246). Morphine dependency also had no significant association with hyperlipidemia with a Crude Odds Ratio (COR) of 0.906 (95%CI=0.786-1.045). CONCLUSION: Morphine dependency was significantly related to MI, but its risk factors were not significantly associated with morphine dependency. The increasing prevalence of opioid abuse in developing countries may be a reason for the growing incidence of MI in younger ages and individuals with no risk factors. Besides, physicians should consider the presence of impurities in morphine-based opioids and their possible effects on health.
