Hygrometry behavior during high-flow nasal oxygen therapy and non-invasive mechanical ventilation: A narrative review of bench to clinical studies

引用

重症医学（英文） 2024年第4期04卷 433-441页

作者： Singhal Sanjay Gurjar Mohan Duan Jun Notaro Salvatore Esquinas antonio M. Department of Pulmonary Medicine All India Institute of Medical Science Rajkot Gujarat India Department of Critical Care Medicine Sanjay Gandhi Post Graduate Institute of Medical Sciences (SGPGIMS) Lucknow India Department of Respiratory and Critical Care Medicine The First Affiliated Hospital of Chongqing Medical University Chongqing China Intensive Care Unit and ECMO A.O.R.N. "Dei Colli" Monaldi Hospital Naples Italy Intensive Care Unit Hospital Morales Meseguer Murcia Spain

Recently, there has been growing interest in knowing the best hygrometry level during high-flow nasal oxygen and non-invasive ventilation (NIV) and its potential influence on the outcome. Various studies have shown that breathing cold and dry air results in excessive water loss by nasal mucosa, reduced mucociliary clearance, increased airway resistance, reduced epithelial cell function, increased inflammation, sloughing of tracheal epithelium, and submucosal inflammation. With the Coronavirus Disease 2019 pandemic, using high-flow nasal oxygen with a heated humidifier has become an emerging form of non-invasive support among clinicians. However, we cannot always assume stable humidification. Similarly, there are no clear guidelines for using humidification during NIV, although humidification of inspired gas during invasive ventilation is an accepted standard of care. NIV disturbs the normal physiological system that warms and humidifies inspired gases. If NIV is supplied through an intensive care unit ventilator that utilizes anhydrous gases from compressed wall air and oxygen, the risk of dryness increases. In addition, patients with acute respiratory failure tend to breathe through the mouth during NIV, which is a less efficient route than nasal breathing for adding heat and moisture to the inspired gas. Obstructive sleep apnea syndrome is one of the most important indications for chronic use of NIV at home. Available data suggest that up to 60% of patients with obstructive sleep apnea syndrome who use continuous positive airway pressure therapy experience nasal congestion and dryness of the mouth and nose. Therefore, humidifying the inspired gas in NIV may be essential for patient comfort and compliance with treatment. We aimed to review the available bench and clinical studies that addressed the utility of hygrometry in NIV and nasal high-flow oxygen and discuss the technical limitations of different humidification systems for both systems.

Fulminant Hepatitis Associated with Chronic Consumption of 3,4-Methylenedioxy-Methamphetamine;Case Report

引用

Open Journal of Gastroenterology 2024年第5期14卷 161-166页

作者： Ulises Solis Gomez Gustavo Adolfo Hernández Valdez Juan antonio Contreras Escamilla Ivan Alejandro Medina Jimenez Jorge Morales Rojas Jocelyn Nataly Quintero Melendez Marco antonio González Villar Department of Internal Medicine ISSSTE APP General Hospital of Tepic Tepic Nayarit Mexico

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA), also called ecstasy, is a neurotoxin widely consumed among young people that has increased in recent years because it is a recreational drug, of which immediate effects are known such as a greater sensation of well-being, extroversion, increased sensory perception. However, its long-term effects have been described very little in the medical literature, including damage to the heart, central nervous system, kidney, etc. One of its little-known effects is hepatotoxicity, of which few cases are known associated with fulminant hepatitis, which is a rapidly deteriorating condition that is generally associated with a syndrome of multiple organ dysfunction and death. Therefore, it is very important to know this type of damage in the short and long term. The following case is of a 39-year-old man who came to our service due to jaundice syndrome and the only history of MDMA consumption, who as the days went by met the criteria for fulminant liver failure, with damage to multiple organs (organ dysfunction syndrome).
