Purpose: Successful resuscitation and early defibrillation are critical in survival after in- or out-of-hospital cardiopulmonary arrest. This study aimed to determine the knowledge, skills, and attitudes of the pediatric healthcare professionals about the defibrillator use and to offer solutions if there was room for improvement. Procedures: This was a multicenter survey study. Findings: The study included 716 healthcare professionals with an average age of 30.1 ± 5.8 years; 50% (n=358) were pediatric residents and 41.3% (n=296) had less than three years of professional experience. Self-declared level of knowledge about defibrillation/cardioversion was low-to-medium for 66.5% (n=476); 60.8% (n=435) had never practiced these procedures and 22.2% (n=159) had never received any training about defibrillator use. There was a significant relationship between professional experience and the proportion of participants who correctly responded to the first-shock dose for defibrillation but not for cardioversion. Conclusion: Professional experience is crucial in the correct defibrillator use. However, the defibrillation/cardioversion procedures are prone to errors since they are not commonly applied in day to day practice. An ideal approach to improve the experience of personnel could be to use practical training with case-based simulations and to educate the personnel about the features of the defibrillators available in their clinics.

Objectives: The aim of our study is to examine the efficacy and safety of intravenous magnesium sulfate in moderate-severe acute bronchiolitis. Working hypothesis: Intravenous magnesium sulfate treatment may be effective in the treatment of patients with bronchiolitis . Study design: Retrospective, single-center cohort study Methodology: We conducted a study in 150 infants presenting with moderate to severe acute bronchiolitis. A total of 150 infants aged 1 month to 2 years who presented with acute bronchiolitis to our pediatric emergency department between January 2018 and March 2019 were admitted into the study. The demographic characteristics, clinical score, and management of the patients were examined. Results: A total of 150 infants were analyzed: 62 in the magnesium sulfate group (Group I) and 88 in the supportive care group (Group II). Baseline clinical characteristics were similar in both groups. Length of hospitalization was significantly shorter in Group II. Clinical severity scores were also lower significantly earlier in Group I (p=0.031, p=0.008, respectively at first and fourth hour). Conclusions: Intravenous magnesium treatment in moderateto severe acute bronchiolitis does not appear to conferany significant decrease in clinical severity scores when compared to only supportive care
