To study monitoring hemodynamics and oxygen dynamics of adult respiratory distress syndrome (ARDS) secondary to high altitude pulmonary edema (HAPE),we performed clinic and laboratory studies in 8 patients who preliminarily developed high altitude cerebral edema (HACE) and then ARDS occurred at an altitude of 4 500 m. After an initial emergency treatment on high mountains,all the patients were rapidly transported to a hospital at a lower altitude of 2 808 m. The right cardiac catheterizations were carried out within 5 h after hospitalized. The monitoring hemodynamics and oxygen dynamics were studied via a thermodilution Swan-Gaze catheter. The results showed that before treatments at the beginning of monitoring,there presented a significant pulmonary artery hypertension with a decreased cardiac function,and a lower oxygen metabolism in all the 8 patients. However,after some effective treatments,including mechanical ventilation and using dexamethasone,furosemide,etc,four days later the result of a repeated monitoring showed that their pulmonary artery pressure had been decreased with an improved cardiac function with all the oxygen metabolic indexes increased significantly. Our studies suggested that performing monitoring hemodynamics in patients with ARDS secondary to HAPE will define the clinical therapeutic measures which will benefit the outcome. 展开更多

Objective:To study the effect of bronchofiberscope airway lavage on respiratory function and inflammatory stress level in adults with severe pneumonia.Methods:80 adults with severe pneumonia treated in our hospital between July 2011 and March 2015 were collected, and after the treatment process and auxiliary examination results were retrospectively analyzed, they were divided into control group (n=45) who accepted conventional treatment and observation group (n=35) who accepted bronchofiberscope airway lavage. Before and after treatment, the spirometer was used to test the respiratory function of two groups of patients;ELISA method was used to detect serum inflammatory factor levels;RIA method was used to detect serum stress index levels.Results:Before treatment, differences in serum levels of inflammatory cytokines and stress indexes were not statistically significant between two groups of patients (P>0.05);after treatment, respiratory function parameters forced expiratory volume in 1 s (FEV1), alveolar ventilation (VA), maximal mid-expiratory flow (FEF25-75), instantaneous late-expiratory flow (FEF50%) and instantaneous late-expiratory flow (FEF75%) levels of observation group were higher than those of control group (P<0.05), serum high mobility group box B1 (HMGB1), interleukin-2 (IL-2), interferonγ (IFN-γ), cortisol (Cor), adrenaline (ADR) and noradrenaline (NADR) levels were significantly lower than those of control group while interleukin-13 (IL-13) level was significantly higher than that of control group (P<0.05). Conclusions: Bronchofiberscope airway lavage can optimize the respiratory function and reduce systemic inflammatory and stress response in adults with severe pneumonia. 展开更多

Acute respiratory distress syndrome (ARDS) remains a poor prognosis in spite of the recent development of new therapeutic strategies. Cell-based therapy with stem cells has been considered as a promising way for the treatment of vital organ damage. Putative endogenous stern cells have been shown to be located within the adult lung in the basal layer of the upper airways, within or near pulmonary neuroendocrine cell rests, at the bronchoalveolar junction, as well as within the alveolar epithelium. These stem cells are hypothesized to be the source of lung regeneration and repair. But this mechanism seems to be insufficient alter lung injury. There is increasing excitement over the last few years with the suggestion that exogenous stem cells may offer new treatment options for ARDS. Exogenous stem cells have the ability to differentiate and function as both airway and lung parenchymal epithelial cells in both in vitro and in- creasingly in vivo experiments. However, there is great controversy concerning the repair effect of adult stem cells in lung injury. This review evaluates the advances in endogenous respiratory stem cells, and assesses the evidence for the use of stem cells in the repair of lung injury. 展开更多

Respiratory failure complicating the course of diabetic ketoacidosis(DKA)is a source of increased morbidity and mortality.Detection of respiratory failure in DKA requires focused clinical monitoring,careful interpretation of arterial blood gases,and investigation for conditions that can affect adversely the respiration.Conditions that compromise respiratory function caused by DKA can be detected at presentation but are usually more prevalent during treatment.These conditions include deficits of potassium,magnesium and phosphate and hydrostatic or non-hydrostatic pulmonary edema.Conditions not caused by DKA that can worsen respiratory function under the added stress of DKA include infections of the respiratory system,pre-existing respiratory or neuromuscular disease and miscellaneous other conditions.Prompt recognition and management of the conditions that can lead to respiratory failure in DKA may prevent respiratory failure and improve mortality from DKA. 展开更多

Acute respiratory distress syndrome(ARDS)-related acute cor pulmonale(ACP)is found in 8%-50%of all patients with ARDS,and is associated with adverse hemodynamic and survival outcomes.ARDS-related ACP is an echocardiographic diagnosis marked by combined right ventricular dilatation and septal dyskinesia,which connote simultaneous diastolic(volume)and systolic(pressure)overload respectively.Risk factors include pneumonia,hypercapnia,hypoxemia,high airway pressures and concomitant pulmonary disease.Current evidence suggests that ARDS-related ACP is amenable to multimodal treatments including ventilator adjustment(aiming for arterial partial pressure of carbon dioxide<60 mmHg,plateau pressure<27 cmH2O,driving pressure<17 cmH2O),prone positioning,fluid balance optimization and pharmacotherapy.Further research is required to elucidate the optimal frequency and duration of routine bedside echocardiography screening for ARDS-related ACP,to more clearly delineate the diagnostic role of transthoracic echocardiography relative to transesophageal echocardiography,and to validate current and novel therapies. 展开更多

BACKGROUND: Pulmonary stretch reflex plays an important role in regulation of respiratorymovement. This study aimed to evaluate the effect of pulmonary stretch reflex on lung injury inrabbits with acute respiratory distress syndrome (ARDS).METHODS: ARDS rabbits were given intratracheal infusion of hydrochloric acid and ventilatedwith neurally adjusted ventilatory assistance (NAVA) with a tidal volume (VT) of 6 mL/kg and theelectrical activity of diaphragm (EAdi)-determined positive end expiratory pressure. After isolation ofthe bilateral vagus nerve trunk, the rabbits were randomized into two groups: sham operation (SHAM)group (n=5) and bilateral vagotomy (VAG) group (n=5). Gas exchange and respiratory mechanicswere detected at baseline, after lung injury and 1, 2, and 3 hours after ventilation respectively.Pulmonary permeability index, pathological changes and infl ammatory response were also measured.RESULTS: Compared with the SHAM group, PaO2/FiO2 in the VAG group decreased signifi cantly2 and 3 hours after ventilation (P〈0.05). There was no significant difference in PaCO2 betweenthe SHAM and VAG groups (P〉0.05), and the VAG group had a high VT, peak pressure (Ppeak),and mean pressure (Pm) compared with the SHAM group 1, 2, 3 hours after ventilation (P〈0.05).Compared to the SHAM group, dead space fraction (VD/VT) and respiratory system elastance (Ers)in the VAG group increased (P〈0.05) and static pulmonary compliance (Cst) decreased markedly(P〈0.05) after ventilation for 3 hours. Lung wet/dry weight ratio (W/D) (8.4±1.2 vs. 6.6±1.0), lung injuryscore (6.3±1.8 vs. 3.8±1.3), tumor necrosis factor-# (TNF-#) (779±372 pg/mL vs. 355±130 pg/mL)and interleukin-8 (IL-8) (169±21 pg/mL vs. 118±17 pg/mL) increased significantly in the VAG groupcompared with the SHAM group (P〈0.05).CONCLUSION: Lung injury is aggravated after bilateral vagotomy, demonstrating thatpulmonary stretch refl ex may have protective effect on the lung. 展开更多
