Sepsis is not only a common critical disease , but also a common complication and cause of death of patients in intensive care unit. It has the characteristics of dangerous condition, rapid development and high mortality. How to treat sepsis to improve the prognosis and quality of life of patients is very important. Timely and reasonable anti-infection is a vatal part in the treatment of sepsis. This article will review the progress of anti-infective therapy in adult patients with sepsis, starting from empirical anti-infection, procalcitonin-guided anti-infection, bacterial culture combined drug sensitivity test-guided anti-infection and anti-infection with antimicrobial peptides, aiming to provide a certain basis and reference for the anti-infective treatment of adult sepsis.
Acute cerebral infarction is characterized by high incidence rate, high recurrence rate, high disability rate and multiple complications. Early evaluation and treatment of acute cerebral infarction is particularly important to improve the survival rate and prognosis of patients. As an easily available clinical laboratory indicator, blood routine test can reflect the pathological changes in the body to a certain extent. In recent years, many studies have shown that the indicators such as red cell volume distribution width, mean platelet volume, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in blood routine examination have important values in the onset, severity and prognosis of acute cerebral infarction. This article reviews the correlations of the above parameters and ratio parameters with acute cerebral infarction, in order to provide some reference and basis for clinical diagnosis, treatment and prognosis evaluation of acute cerebral infarction.
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.
