The number of cases of extracorporeal membrane oxygenation (ECMO) has rapidly increased all over Korea since the introduction of peripheral cannulation catheters. However, the application of ECMO to children has been limited due to the shortage of pediatric equipment and difficulty in maintaining an ECMO system with peripheral cannulation. For this reason, there have been only few reports of pediatric ECMO in Korea, and most of them pertained to the veno-arterial type ECMO for supporting the cardiac system in postcardiotomy patients. We report here on the successfully performing veno-venous ECMO, with using a double lumen percutaneous catheter, in a child with acute respiratory distress syndrome.

Purpose: This study aimed to identify the colonization rate of carbapenem-resistant Enterobacteriaceae (CRE), the characteristics of CRE isolates, and risk factors for CRE colonization in patients transferred to the general wards of a small/medium-sized hospital. Methods: This retrospective study was conducted on patients who underwent CRE culture tests within 24 hours of admission among patients transferred to a small/medium-sized hospital. Forty-seven patients confirmed as positive for CRE were classified as belonging to the patient group. For the control group, 235 patients (five times the number of the patient group) were matched by sex, age, and diagnosis, and then selected at random. Data were analyzed using descriptive analysis and multiple logistic regression analysis. Results: The CRE colonization rate was 5% (47 out of 933 patients), and Klebsiella pneumoniae (68.0%) was the most common isolate of CRE. The positivity rate of carbapenemase-producing Enterobacteriaceae was 61.7%. The risk factors for CRE colonization included renal disease (odds ratio [OR]=4.93; 95% confidence interval [CI], 1.49-16.31), heart disease (OR=3.86; 95% CI, 1.35-11.01), indwelling urinary catheters (OR=4.43; 95% CI, 1.59-12.36), and cephalosporin antibiotic use (OR=8.57; 95% CI, 1.23-59.60). Conclusion: Having a comorbid renal or cardiac disease, an indwelling urinary catheter, or a history of exposure to cephalosporin antibiotics could be classified as risk factors for CRE colonization in patients transferred to small and medium-size hospitals. It is necessary to perform active infection control through proactive CRE culture testing of patients with risk factors.

Purpose : Radiofrequency catheter ablation (RFCA) has become an effective therapeutic modality for treating pediatric tachyarrhythmias. Using conventional RFCA catheters, ablation of parahisian accessory pathways may be difficult and have high risk for heart block. We reviewed the efficacy and complications of the RFCA in children and adolescent with arrhythmias including parahisian accessory pathways. Methods : We studied 48 patients (aged 2 years to 20 years) who had undergone RFCA from August 2003 to March 2007. We reviewed clinical findings, electrophysiologic studies, RFCA data, complications, and follow-up results of the patients. Results : Mean age of the patients was 13.1 years. Numbers and types of arrhythmias (age, acute success rate) were as follows: 19 WPW syndrome including 5 parahisian accessory pathways ($13.7{\pm}4.6yr$, 18/19), 11 atrioventricular reentrant tachycardia with concealed bypass tract ($12.3{\pm}5.0yr$, 10/11), 13 atrioventricular nodal reentrant tachycardia ($12.6{\pm}4.4yr$, 13/13), 4 atrial flutter ($13.0{\pm}7.4yr$, 3/4), and 1 ventricular tachycardia (20 yr, 1/1). Associated cardiac structural lesion was not detected in 48 patients. The recurrence rate was 6.5%, and the final success rate was 93.8%. Conclusion : These results suggest that RFCA is a highly effective treatment method in children and adolescent with tachyarrhythmia.
