Acute carbon monoxide poisoning is a common and frequently occurring disease in winter and spring in China, with high disability and mortality. Delayed encephalopathy is a serious sequela after the pseudo-convalescence. Its mechanism is complex, including environmental and genetic factors, hypoxia and energy metabolism disorder, cytotoxicity and oxygen free radical damage, immune disorder and inflammatory activation, neurotransmitter disorder, brain parenchymal changes, vascular and hemorheological abnormalities, calcium overload, and cell apoptosis. At present, methods for predicting delayed encephalopathy in acute carbon monoxide poisoning include detailed inquiry of medical history, laboratory examination of relevant indicators, electrophysiological examination, brain imaging examination, and evaluation scale prediction. This review summarizes the research status of the pathogenesis and early prediction methods of delayed encephalopathy in acute carbon monoxide poisoning, with a view to providing reference for future research directions.
Acute respiratory distress syndrome is one of the forms of respiratory failure that seriously threaten human life. It has the characteristics of very high morbidity, mortality and hospitalization costs. How to treat acute respiratory distress syndrome to improve the quality of life of patients is particularly important. Mechanical ventilation is an important treatment for acute respiratory distress syndrome. This article will review the progress in mechanical ventilation therapy for acute respiratory distress syndrome, including non-invasive mechanical ventilation and invasive mechanical ventilation (tidal volume, lung recruitment, positive end-expiratory pressure, prone position ventilation, and high-frequency oscillatory ventilation), aiming to provide basis and reference for future exploration of the treatment direction of acute respiratory distress syndrome.
