Clinical features of adolescents who visited the emergency department with chest discomfort: the importance of recognizing underlying medical conditions

Purpose We aimed to evaluate the clinical features of adolescents who visit emergency departments (EDs) with chest discomfort, and analyze the implications of underlying medical conditions for the development of cardiogenic chest discomfort. Methods We reviewed the medical records of adolescents (13-18 years) with chest discomfort who visited a tertiary hospital ED in Seoul, Korea from 2014 through 2018. Sex, age, duration and character of the discomfort, symptoms and signs, ED length of stay, abnormal findings of vital signs, chest radiograph, electrocardiogram, and elevated concentrations of cardiac enzymes were reviewed. Final diagnosis was based on cardiac evaluations within 1 year after the index visit. Underlying medical conditions were defined as visits to the cardiology, pulmonology or hematology-oncology clinics at least twice in the preceding year. Initial suspicious clinical findings were defined as palpitation, syncope or high blood pressure. Logistic regression was used to identify predictors for cardiac etiology. Results Of the 231 patients, 43 (18.6%) and 69 (29.9%) had underlying medical conditions and initial suspicious clinical findings, respectively. The predictors for cardiac etiology were underlying medical conditions (odds ratio, 4.28; 95% confidence interval, 1.09-16.73), initial suspicious clinical findings (4.77; 1.36-16.77), abnormal electrocardiogram (11.54; 3.22-41.32), and elevated concentration of troponin I (66.52; 5.37-823.55). The patients with cardiogenic chest discomfort had a longer median ED length of stay (281.0 minutes [interquartile range, 215.5-369.0] vs. 199.5 [132.8-298.0]; P = 0.004) and a higher hospitalization rate (48.3% vs. 13.4%; P < 0.001) than those with non-cardiogenic chest discomfort. Conclusion It may be necessary to recognize underlying medical conditions and initial suspicious clinical findings in EDs prior to cardiac evaluation in adolescents with chest discomfort

Tuberculosis-associated hemophagocytic lymphohistiocytosis in adolescent diagnosed by polymerase chain reaction

We present a case of tuberculosis-associated hemophagocytic lymphohistiocytosis in a 14-year-old girl. The patient presented with weight loss, malaise, fatigue, prolonged fever, and generalized lymphadenopathy. Laboratory investigation revealed pancytopenia (white blood cells, 2,020 cells/µL; hemoglobin, 10.2 g/dL; platelets, 52,000 cells/µL), hypertriglyceridemia (229 mg/dL), and hyperferritinemia (1,420 ng/mL). Bone marrow biopsy showed a hypocellular bone marrow with a large numbers of histiocytes and marked hemophagocytosis; based on these findings, she was diagnosed with hemophagocytic lymphohistiocytosis. Polymerase chain reaction (PCR) with both the bone marrow aspiration and sputum samples revealed the presence of Mycobacterium tuberculosis. Antitubercular therapy with immune modulation therapy including dexamethasone and intravenous immunoglobulin was initiated. The results of all laboratory tests including bone marrow biopsy and PCR with both the bone marrow aspiration and sputum samples were normalized after treatment. Thus, early bone marrow biopsy and the use of techniques such as PCR can avoid delays in diagnosis and improve the survival rates of patients with tuberculosis-associated hemophagocytic lymphohistiocytosis

2009 H1N1 influenza virus infection and necrotizing pneumonia treated with extracorporeal membrane oxygenation

A 3-year-old girl with acute respiratory distress syndrome due to a H1N1 2009 influenza virus infection was complicated by necrotizing pneumonia was successfully treated with extracorporeal membrane oxygenation (ECMO). This is the first reported case in which a pediatric patient was rescued with ECMO during the H1N1 influenza epidemic in Korea in 2009

Individualized Goal Setting for Pediatric Intensive Care Unit-Based Rehabilitation Using the Canadian Occupational Performance Measure

The Canadian Occupational Performance Measure (COPM) is a client-centered outcome measure that facilitates the prioritization of individualized interventions. Given the rising emphasis on individualized intervention in pediatric intensive care units (PICUs), this cross-sectional study aimed to explore caregivers’ perspectives on their children’s functional goals within PICUs. From 1 September 2020 to 26 June 2022, caregivers of 41 children aged 1–18 years completed the COPM within 48 h of PICU admission. The study also explored the clinical variables predicting a high number of occupational performance goals (≥4/5). Out of 190 goals proposed by caregivers, 87 (45.8%) pertained to occupational performance, while 103 (54.2%) were related to personal factors. Among the occupational performance goals, the majority were associated with functional mobility (55; 28.9%), followed by personal care (29; 15.2%) and quiet recreation (3; 1.6%). Among personal goals, physiological factors (68; 35.8%) were most common, followed by physical factors (35; 18.4%). We found caregiver anxiety, measured by the State-Trait Anxiety Inventory-State, to be a significant predictor of the number of occupational performance goals. These findings underscore the importance of caregiver psychological assessment in the PICU to facilitate personalized goal setting and improve rehabilitation outcomes

Trends in Incidences and Survival Rates in Pediatric In‐Hospital Cardiopulmonary Resuscitation: A Korean Population‐Based Study

Background Although the outcome of cardiopulmonary resuscitation (CPR) is still unsatisfactory, there are few studies about temporal trends of in‐hospital CPR incidence and mortality. We aimed to evaluate nationwide trends of in‐hospital CPR incidence and its associated risk factors and mortality in pediatric patients using a database of the Korean National Health Insurance between 2012 and 2018. Methods and Results We excluded neonates and neonatal intensive care unit admissions. Incidence of in‐hospital pediatric CPR was 0.58 per 1000 admissions (3165 CPR/5 429 471 admissions), and the associated mortality was 50.4%. Change in CPR incidence according to year was not significant in an adjusted analysis (P=0.234). However, CPR mortality increased significantly by 6.6% every year in an adjusted analysis (P<0.001). Hospitals supporting pediatric critical care showed 37.7% lower odds of CPR incidence (P<0.001) and 27.5% lower odds of mortality compared with other hospitals in the adjusted analysis (P<0.001), and they did not show an increase in mortality (P for trend=0.882). Conclusions Temporal trends of in‐hospital CPR mortality worsened in Korea, and the trends differed according to subgroups. Study results highlight the need for ongoing evaluation of CPR trends and for further CPR outcome improvement among hospitalized children

Effects of continuous ketamine infusion on hemodynamics and mortality in critically ill children.

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 rates for continuous ketamine and Non-ketamine groups were compared by multivariate logistic regression. A total of 240 patients used continuous sedation, and 82 used continuous ketamine. The median infusion rate of ketamine was 8.1 mcg/kg/min, and the median duration was 6 days. Heart rates (138 vs. 135 beat/minute, P = .033) and respiratory rates (31 vs. 25 respiration/minute, P = .001) decreased, but blood pressure (99.9 vs. 101.1 mm Hg, P = .124) and vasogenic medications did not change after ketamine infusion. Continuous ketamine was not a significant risk factor for mortality (hazard ratio 1.352, confidence interval 0.458-3.996). Continous ketamine could be used in PICU without hemodynamic instability. Further studies in randomized controlled design about the effects of continuous ketamine infusion on hemodynamic changes, sedation, and mortality are required

Safety and Feasibility of Percutaneous Dilatational Tracheostomy Performed by Intensive Care Trainee

Background: Percutaneous dilatational tracheostomy (PDT) performed by an intensivist in critically ill patients is currently popular. Many studies support the safety and feasibility of PDT. However, there is limited data on the safety and feasibility of PDT performed by intensive care trainees. Methods: To evaluate the safety and feasibility of PDT performed by intensive care trainees and to compare these with those performed by intensivists, we retrospectively analyzed the clinical characteristics and adverse events of all prospectively registered patients who underwent PDT by ICT or intensivists in intensive care units (ICUs) from August 2010 to August 2013. Results: In the study period, 203 patients underwent PDT in ICUs; 139 (68%) by trainees and 64 (32%) by intensivists. There were no statistically significant differences in clinical characteristics including demographics, laboratory findings, and parameters of mechanical ventilation between the two groups. Procedure times and outcomes of the patients were not different between the two groups. The majority of complications observed in 24 hours after PDT were bleeding; however, there was no significant difference between the two groups (trainee 10.8% vs. intensivist 9.4%, p = 0.758). There was no procedure-related death in the two groups. Conclusions: PDT performed by intensive care trainees was safe and feasible. However, further well-designed studies should be conducted to confirm our results

Respiratory Complications Associated with Insertion of Small-Bore Feeding Tube in Critically Ill Patients

Small-bore flexible feeding tubes decrease the risk of ulceration of the nose, pharynx, and stomach compared with large-bore and more rigid tubes. However, small-bore feeding tubes have more respiratory system complications, such as pneumothorax, hydropneumothorax, bronchopleural fistula, and pneumonia, which are associated with significant morbidity and mortality. Thus, it is important to confirm the correct position of feeding tubes. Chest X-ray is the gold standard to detect tracheal malpositioning of the feeding tube. We present three cases in which intubated patients exhibited an altered mental state. An assistant guide wire was used at the insertion of small-bore feeding tubes. These conditions are thought to be potential risk factors for tracheobronchial malpositioning of feeding tubes
