Severe Lung Dysfunction and Pulmonary Blood Flow during Extracorporeal Membrane Oxygenation.

Background: Extracorporeal membrane oxygenation (ECMO) is indicated for patients with severe respiratory and/or circulatory failure. The standard technique to visualize the extent of pulmonary damage during ECMO is computed tomography (CT).

Purpose: This single-center, retrospective study investigated whether pulmonary blood flow (PBF) measured with echocardiography can assist in assessing the extent of pulmonary damage and whether echocardiography and CT findings are associated with patient outcomes.

Diagnosis of foreign body aspiration with ultralow-dose CT using a tin filter: a comparison study.

Purpose: Suspected airway foreign body aspiration (FBA) is a common event in paediatric emergency units, especially in children under 3 years of age. It can be a life-threatening event if not diagnosed promptly and accurately. The purpose of this study is to compare the diagnostic performance of an ultralow-dose CT (DLP of around 1 mGycm) with that of conventional radiographic methods (fluoroscopy and chest radiography of the airways) in the diagnosis of FBA children's airways.

Long-term pulmonary function and quality of life in adults after extracorporeal membrane oxygenation for respiratory failure.

Background: There is a significant long-term burden on survivors after acute respiratory distress syndrome, even 5 years after discharge. This is not well investigated in patients treated with extracorporeal membrane oxygenation. The objective of this study was to describe very-long-term (⩾3 years) disability in lung function and morphology, quality of life, mood disorders, walking capacity, and return to work status in extracorporeal membrane oxygenation survivors.

Predicting asthma morbidity in children using proposed markers of Th2-type inflammation.

Background: Assessment of inflammation is becoming a common practice in the clinical work-up of children with persistent asthma. Biomarkers of Th2-mediated inflammation include blood eosinophils (B-Eos), exhaled nitric oxide (FeNO), total serum IgE (S-IgE), and serum periostin. The aim of this study was to investigate the associations between asthma morbidity and increased levels of these biomarkers in pediatric asthma.

The chitinase-like protein YKL-40: a possible biomarker of inflammation and airway remodeling in severe pediatric asthma.

Background: Problematic severe childhood asthma includes a subgroup of patients who are resistant to therapy. The specific mechanisms involved are unknown, and novel biomarkers are required to facilitate treatment and diagnosis of therapy-resistant asthma. The chitinase-like protein YKL-40 has been related to asthma and airway remodeling.

Problematic severe asthma: a proposed approach to identifying children who are severely resistant to therapy.

Children with problematic severe asthma (PA) are either difficult to treat because of the presence of aggravating factors or else severely resistant to therapy. We investigated a cohort of school-aged children with PA and compared these children to age-matched peers with controlled persistent asthma (CA). The aims were to characterize features of children suffering from PA and identify children who were severely resistant to therapy.

Cranial CT for diagnosis of intracranial complications in adult and pediatric patients during ECMO: Clinical benefits in diagnosis and treatment.

Rationale And Objectives: To evaluate the clinical utility of cranial computed tomography (CT) in pediatric and adult patients during ongoing extracorporeal membrane oxygenation (ECMO) treatment from acute respiratory failure and to assess the frequency of intracranial hemorrhage (ICH) and infarction during the treatment.

Materials And Methods: The medical records of 123 consecutive patients, 54 children (ages 3 months-17 years) and 69 adults (ages 18-62 years), treated with ECMO over a 10-year period were searched for cranial CT performed during ECMO. Indications for CT, CT findings, impact on clinical management, and patient outcome were noted.

MRI of the brain and thorax during extracorporeal membrane oxygenation: preliminary report from a pig model.

Early diagnosis of cerebral hypoxic ischemic complications during extracorporeal membrane oxygenation (ECMO) is important to guide further treatment. However, diagnostic methods available during ECMO are limited, especially in adults and older children. Magnetic resonance imaging (MRI) is a sensitive and noninvasive method for assessment of vessel patency and brain parenchymal changes, and for measurement of brain perfusion.

Chest and abdominal CT during extracorporeal membrane oxygenation: Clinical benefits in diagnosis and treatment.

Rationale And Objective: This study aims to evaluate the clinical usefulness of thoracic and abdominal computed tomography (CT) as an adjunct to bedside diagnostic imaging in patients on extracorporeal membrane oxygenation (ECMO) therapy because of severe acute respiratory failure.

Materials And Methods: Imaging records for 118 consecutive thoracic and abdominal CT examinations performed in 63 patients (22 neonates, 15 children, and 26 adults) on ECMO therapy during an 8-year period were retrospectively reviewed. Reported CT findings were compared with concurrent bedside radiographs and ultrasounds.

CT in the evaluation of patients on ECMO due to acute respiratory failure.

Background: In patients with acute severe respiratory failure (ARF) treated with extracorporeal membrane oxygenation (ECMO) the radiological evaluation has until now almost exclusively relied on bedside radiography and US. At St. Göran/Karolinska ECMO centre CT has become a routine complement to bedside examinations.
