BACKGROUND: Despite the high workload of mechanical ventilation, there has been a lack of studies on the association between nurse workforce and mortality in mechanically ventilated patients. We evaluated the association of the bed-to-nurse ratio with mortality in ventilated pediatric patients admitted to an intensive care unit (ICU). METHODS: We conducted a nationwide retrospective analysis by using the Korean National Health Insurance database, which categorizes the bed-to-nurse ratio into 9 g

We investigated the hemodynamic and mortality effects of continuous ketamine infusion in critically ill pediatric patients. We conducted a retrospective cohort study in a tertiary pediatric intensive care unit (PICU). Patients who used continuous sedative from 2015 to 2017 for 24 hours or more were included. We compared blood pressure, heart and respiratory rates, vasogenic medications, and sedation and pain scores for 12 hours before and after initiation of continuous ketamine. The mortality ra

The 40-50 kDa protein is implicated as an important allergen to predict moderate-to-severe clinical symptoms in Korean children with buckwheat allergy.

Purpose : The aim of this study was to longitudinally examine the correlation between the change of atopic dermatitis (AD) severity and the change of quality of life (QOL).

BACKGROUND: The outcomes of weaning processes are not well known in pediatric patients, and the International Conference Classification on weaning from mechanical ventilation showed limited application. We evaluate the relationship between the new Weaning according to a New Definition (WIND) classification and outcome in pediatric patients. METHODS: We conducted a retrospective cohort study in a tertiary pediatric intensive care unit (ICU). We included patients under 18 years of age who received

BACKGROUND AND OBJECTIVE: High-dose chemotherapy (HDCT) followed by autologous haematopoietic stem cell transplantation (HSCT) is widely used in paediatric cancer patients, but few data about noninfectious interstitial lung disease (ILD) following this treatment are available. Therefore, we aimed to evaluate the incidence, clinical features and risk factors of noninfectious ILD after HDCT in paediatric patients. METHODS: This was a retrospective cohort study of paediatric solid tumour patients w

PURPOSE: Intensive care unit (ICU) survivors suffer from physical weakness and challenges returning to daily life. With the importance of rehabilitating patients in the pediatric intensive care unit being increasingly recognized, we evaluated the prevalence of physical and occupational therapy (PT/OT)-provided rehabilitation and factors affecting its use. METHODS: We conducted a retrospective cohort analysis of rehabilitation between 2013 and 2019 using the Korean National Health Insurance datab

BACKGROUND: There is a lack of nationwide studies on critically ill patients' health disparity under the National Health Insurance (NHI) system. We evaluated health disparities in intensive care unit (ICU) admission, outcomes, and readmission in impoverished children. METHODS: We conducted a retrospective cohort study using a national database from the Korean NHI and Medical Aid Program (MAP). MAP supports the population whose household income is lower than 40% of the median Korean household inc

AIMS: Because of limitations with the serum creatinine-based glomerular filtration rate (GFRcr), estimates of the serum cystatin C-based glomerular filtration rate (GFRcys) are getting attention to predict vancomycin clearance (CLvan). We evaluated the correlations between (i) CLvan and GFRcr, and (ii) CLvan and GFRcys in paediatric patients. METHODS: We evaluated a retrospective cohort of patients between 1 and 19 years old admitted to a tertiary hospital between 2017 and 2019. CLvan was estima

Managing acute respiratory distress syndrome (ARDS) after severe blunt traumatic lung injury can be challenging. In cases where patients are refractory to conventional therapy, extracorporeal membrane oxygenation (ECMO) should be considered. In addition, the heparin-coated circuit can reduce hemorrhagic complications in patients with multiple traumas. Although prolonged ECMO may be necessary, excellent outcomes are frequently associated. In this study, we report long-term support with venovenous

OBJECTIVE: In order to improve the outcome and to reduce the post-operative care burden following the anterior cricoid split procedure, we modified the procedure to involve splitting only the cricoid cartilage, not the mucosa deep to the cartilage. In addition, we transposed the cricoid cartilage segment after division of the cricoid ring in the midline. CASE REPORT: We present the use of our modification in a 19-month-old boy with early-stage subglottic stenosis. RESULTS: The technique was perf

Purpose The aim of this study was to compare the effects of breast milk (BM) feeding with those of maternal cow milk (CM) restriction and extensively hydrolyzed CM formula feeding on the duration of CM allergy as well as changes in specific immunoglobulin E (IgE) levels in infants with CM allergy. Methods Children diagnosed with CM allergy before 12 months age and BM fed were included retrospectively. CM allergy was diagnosed by CM specific IgE over 0.35 kU/L and 1) obvious clinical symptoms, 2)

Pyriform sinus perforation is uncommon in children and most cases are secondary to iatrogenic causes such as endotracheal intubations. Due to this rarity, the management of these injuries is controversial. We report a case of pyriform sinus perforation in a 14-month-old boy who fell down with a spoon handle in the mouth and was successfully treated by transoral laryngomicrosurgery. Two hours after falling down, the patient had breathing difficulties and started vomiting. A chest X-ray showed sub
