IS CARDIOPULMONARY RESUSCITATION OUTCOME IN PRE-HOSPITAL EMERGENCY MEDICINE RELATED TO AIRWAY MANAGEMENT TECHNIQUE?

According to current European Resuscitation Council guidelines, priorities in advanced life support in adult are chest compression with minimal interruption and early defibrillation. Endotracheal intubation is still considered the gold standard in airway management, but guidelines suggest that securing the airway be incremental, ranging from basic techniques to more complex ones. Doctors who work in pre-hospital emergency medicine teams (EMT) in Croatia usually lack sufficient education and expertise. The aim of this study was to determine whether there was a significant difference in recovery of spontaneous circulation during cardiopulmonary resuscitation (CPR) in out-of-hospital setting depending on the EMT airway management technique of choice. This retrospective analysis included data collected during a 10-year period at the Krapina-Zagorje County Emergency Medicine Institute on all patients with CPR performed by EMTs 20 minutes from initial emergency call. The airway management groups included oropharyngeal tube, i-gel supraglottic device, and endotracheal tube. There were 968 patients, mean age 70. In 74.61% of patients, the cause of arrest was of cardiac etiology. Our study did not find a statistically significant in difference of CPR success among the three groups analyzed according to the airway management technique of choice (p=0.74, χ2-test).

ANTIPLATELET THERAPY AFTER CORONARY ARTERY BYPASS GRAFT SURGERY - UNEVENNESS OF DAILY CLINICAL PRACTICE.

Antiplatelet therapy is an integral part of optimal medicamentous therapy in patients with coronary artery disease. The strategy of antiplatelet/anticoagulant therapy is adjusted (combination of drugs, dosing and duration of therapy) depending on the stage of the disease (acute coronary syndrome with percutaneous coronary intervention, chronic coronary syndrome, or coronary surgical revascularization) and comorbidity of each patient (e.g., atrial fibrillation, left ventricular thrombus, etc.). Guidelines and clinical practice in particular are not uniform and specific regarding dual antiplatelet therapy in patients undergoing coronary artery bypass grafting, especially in the setting of chronic coronary syndrome.

Characteristics of heart rate variability in war veterans with post-traumatic stress disorder after myocardial infarction.

OBJECTIVE: The goal of the study was to evaluate differences in heart rate variability (HRV) among post-myocardial infarction (MI) patients, depending on their participation in the Croatian war and on established diagnoses of post-traumatic stress disorder (PTSD). METHODS: The study included 34 male war veterans with diagnosed PTSD who had suffered a first MI and 34 age-matched post-MI patients without PTSD. Cardiac autonomic balance was evaluated through HRV analysis. RESULTS: There were no differences in the mean R-R interval or overall HRV between the analyzed groups. Post-MI patients with PTSD had lower values for the square root of the mean of squared successive differences in R-R intervals (p = 0.02), the percentage of R-R intervals that were > or =50 milliseconds different from the previous interval (p = 0.03), and the high-frequency component (p = 0.03) but had higher values for the low-frequency component (p = 0.01) and the low-frequency/high-frequency ratio (p = 0.02), compared with post-MI patients without PTSD. CONCLUSION: Post-MI patients with PTSD have higher sympathetic and lower parasympathetic heart rate modulation activity, compared with patients with MI and no PTSD.
