Stridor in children

2018

A 16-month-old boy was referred to the emergency department of the Children's Clinical University Hospital (Riga, Latvia) due to cough and noisy breathing for 3 months. The complaints seemed to have worsened over time with coughing fits 2–4 days a week and the boy not being able to tolerate solid food (leading to vomiting) during the fits. In between the bouts, he felt fine. Diminished food intake was noted over the last month. Over the 3-month period, no other symptoms were noted. The father of the child was fixated on a diagnosis of asthma and categorically denied the possibility of any choking attacks after eating or playing with small objects. The boy had been seen by pulmonologist once…

Fever and dyspnoea in a tracheostomised patient

2020

A 65-year-old man was referred for evaluation of acute onset of fever, productive cough and dyspnoea. He had previously received a diagnosis of laryngeal carcinoma, which had been treated with laryngectomy and bilateral laterocervical lymphadenectomy, followed by chemotherapy. He underwent plastic surgery of the laryngocutaneous fistula, and a positron emission tomography (PET)- computed tomography (CT) examination performed during follow-up showed 18-FDG (2-fluoro-2-deoxyd- glucose) lung uptake in the apical right portion. He had a smoking history and his regular medications included dexamethasone, metoclopramide, omeprazole, furosemide, cholecalciferol and pregabalin. He had a history of …

Noninvasive Ventilation in Critically Ill Patients

2015

Since its first application in the late 1980s, noninvasive ventilation (NIV) has been the first-line intervention for certain forms of acute respiratory failure. NIV may be delivered through the patient's mouth, nose, or both using noninvasive intermittent positive pressure ventilation or continuous positive airway pressure. When applied appropriately, NIV may reduce morbidity and mortality and may avert iatrogenic complications and infections associated with invasive mechanical ventilation. This article provides physicians and respiratory therapists with a comprehensive, practical guideline for using NIV in critical care. © 2015 Elsevier Inc.

A survey on sleep assessment methods

2018

Purpose A literature review is presented that aims to summarize and compare current methods to evaluate sleep. Methods Current sleep assessment methods have been classified according to different criteria; e.g., objective (polysomnography, actigraphy…) vs. subjective (sleep questionnaires, diaries…), contact vs. contactless devices, and need for medical assistance vs. self-assessment. A comparison of validation studies is carried out for each method, identifying their sensitivity and specificity reported in the literature. Finally, the state of the market has also been reviewed with respect to customers’ opinions about current sleep apps. Results A taxonomy that classifies the sleep detect…

Le burn-out en réanimation : évaluation, prévention et dispositifs d’intervention

2020

Les professionnels de réanimation sont confrontés de façon répétitives et intenses à de nombreux facteurs de stress les rendant plus vulnérables au développement d’un burn-out. Le burn-out constitue le stade final d’une rupture d’adaptation suite à un déséquilibre entre les exigences professionnelles et les ressources de l’individu. Il affecte directement la santé mentale et physique des professionnels et est associé à une diminution de la qualité et de la sécurité des soins et à une augmentation des départs des professionnels les plus expérimentés pour d’autres services. En réanimation de nombreuses études ont été menées sur les professionnels et les organisations lancent des appels à l’ac…

19F-MRI of perflubron for measurement of oxygen partial pressure in porcine lungs during partial liquid ventilation

2001

A method for in vivo measurement of oxygen partial pressure (pO2) in porcine lungs during partial liquid ventilation (PLV) with perflubron (PFOB) was developed. A pulse sequence for high-resolution MRI of the distribution of PFOB in the lung after intratracheal administration was developed as well. Moreover, quantitative measurements of longitudinal relaxation time T(1) of (19)F resonances for assessment of regional pO2 are described. Due to the need to acquire data during a single expiratory breathhold, only low SNRs were achieved in vivo. Therefore, simulations were performed to investigate the influence of background noise on T(1) values calculated from data with low SNR. Based on these …

Visualization of inert gas wash-out during high-frequency oscillatory ventilation using fluorine-19 MRI

2010

High-frequency oscillatory ventilation is looked upon as a lung-protective ventilation strategy. For a further clarification of the physical processes promoting gas transport, a visualization of gas flow and the distribution of ventilation are of considerable interest. Therefore, fluorine-19 magnetic resonance imaging of the imaging gas octafluorocyclobutane (C(4) F(8) ) during high-frequency oscillatory ventilation was performed in five healthy pigs. For that, a mutually compatible ventilation-imaging system was set up and transverse images were acquired every 5 sec using FLASH sequences on a 1.5 T scanner. Despite a drop in signal-to-noise ratio after the onset of high-frequency oscillato…

Is Persistent Thick Copious Mucus a Long-Term Symptom of COVID-19?

2020

Introduction The typical clinical picture of COVID-19 is gradually becoming clearer, both in the acute phase and in the long-term. However, new symptoms are gradually being identified. We describe a long-term symptom that has not yet been reported. Case description A 49-year-old man consulted for persistent asthenia. The general practitioner found a fever (39.2°C), and COVID-19 was confirmed by the polymerase chain reaction test. Further symptoms appeared, notably thick, white, painless tracheal hypersecretion for 3 months before diminishing, without disappearing. Conclusion Non-inflammatory tracheal hypersecretion, not yet reported in COVID-19, may be an additional long-term symptom. The h…

Analysis and review of the perioperative management of COVID-19 patients in thoracic surgery.

2021

Resumen Debido a la grave situacion de pandemia que vivimos causada por el COVID-19, la Seccion de Anestesia Cardiaca, Vascular y Toracica de la SEDAR pretende dar informacion de los aspectos mas relevantes a considerar en pacientes con sospecha o infeccion confirmada por coronavirus que van a ser sometidos a cirugia toracica. Creemos que es esencial mantener una optima transmision de informacion para llevar a cabo maniobras seguras, tanto para los pacientes como para el personal sanitario. La estrategia de manejo debe basarse en una organizacion exquisita del trabajo, definiendo quien, como y cuando va a realizar cada tarea y procedimiento. Las recomendaciones que se proponen, tras valorar…
