Full textIn the present study we examined the effects of inhaling nitric oxide (NO) on pulmonary hemodynamics and gas exchange in an ovine model of adult respiratory distress syndrome (AROS), induced by repeated lung lavages. In addition we investigated in this modal the effects of inhibition endogenous NO synthesis by NG-nitro-Larginine metyl ester (L-NAKE) and the combination with inhaled NO. Because NO activates guanylate cyclase, increasing guanosine 3’-5'- cyclic monophosphate (cGMP) we also we measured cGMP plasma levels. In anesthetized and mechanically ventilated sheep inhaling 60 ppm of NO after lung lavage decreased pulmonary artery pressure and resistance without any systemic hemodynamic effects, increased arterial PaO(2) and decreased venous admixture (Q(VA)/Q(I)). A L-NAME infusion produced pulmonary and systemic vasoconstriction without changes on PaO(2) or (Q(VA)/Q(I)) inhaling NO after L-NAME produced the same hemodynamics and gas exchange effects than inhaling NO alone. The effects on inhaled NO were independent of pulmonary blood flow or cardiac output. During NO inhalation plasma cGMP levels were increased significantly. We concluded that in this experimental model of AROS inhaled NO produced selective pulmonary vasodilatation and improved gas exchange by incressing cGMP concentration in ventilated lung regions and these effects were not potentiated with the inhibition of endogenous NO synthesis.

Full textThe use of non invasive mechanical ventilation (NIMV) in the treatment of patients with chronic obstructive pulmonary disease sharpness and acute lung cardiogenic edema, is widely accepted. Its utility in the treatment of the acute hypoxemic respiratory failure and, above all, in more severe forms, as in acute respiratory distress syndrome (ARDS) , is controversial. Objectives. The main objectives of this study were to know the effectiveness of the adapted in the treatment of patients with ARDS, security through the analysis of complications, as well as establishing the factors and risks associated with the outcome of the adapted with splitting hospital, in this group of patients. Material and methods. Observational study, prospective, study carried out in intensive care unit of the University General hospital JM Morales Meseguer of Murcia, between June 1997 and December 2012. Included patients who consecutively presented criteria for ARDS, according to the definition in force in each period, and that required adapted. Held collection of sociodemographic, clinical data, analytical and evolutionary. Success of the adapted was defined when the endotracheal intubation was avoided and the patient was alive discharged from the ICU, staying in plant and adapted without at least 24 hours. Data are expressed as mean ± standard deviation, absolute and relative frequencies. Comparisons between variables using Pearson Chi2 and Student's T test. Multivariate analyses using logistic regression. It has been used the SPSS program version 22.0 for Windows. Results. We have analyzed 421 episodes of ARDS treated with NIMV. The mean age was 58.3 ± 20.2 years and 59.5% were men. The most frequent cause of ARDS was infectious pathology. Gravity as measured by the SAPS II index was 48 ± 15.5. The most widely used fan was the BiPAP Vision, using BiPAP mode in 388 patients. The IPAP and EPAP levels at the beginning of therapy were 15 ± 1.4 and 7.5 ± 0.9, respectively. At the beginning of the therapy, the value of respiratory rate and the PaO2/FiO2 was 35.8 ± 5.6 and 130.1 ± 34.6 respectively; after an hour of NIMV was 33.5 ± 4.9 and 149 ± 37, (p 0.001). The value of the index during the period of adapted SOFA was 11.1 ± 5. 187 patients (44.4) presented complications related to the adapted, being the most frequent skin lesion (150; 35.6%). The success of NIV and in-hospital mortality were 26.8% and 51.3%. By multivariate analysis, predictive success of adapted factors were age (OR 0.978, 95% CI 0.961-0.995), SAPS II (OR 0.969, 95% CI 0.94-0.995), SOFA Max during adapted (OR 0.821, 95%CI 0.736-0.917), level of basal bicarbonate (OR 1.160, IC-95% 1.082-1.243), relationship PaO2/FiO2 and rate of breathing, after an hour of therapy initiated (OR 1.042, 95%CI 1.028-1.056 and OR 0.795, IC-95%, 0.735-0.861). Predictive factors of mortality were the order of not intubation (OR 6.57, 95% CI 2.293-18.826), index score total maximum SOFA (OR 1.436, CI-95% 1.31-1.575), presence of cancer (OR 3.91, CI-95% 1.778-8.595), the age (OR 1.031, CI-95% 1.014-1.049), and the success of the NIMV (OR 0.122, CI-95% 0.041-0.359), Conclusions. The use of the NIMV in the treatment of ARF due to ARDS has a very high failure rate, but with few serious complications. Factors related to the failure of the technique are usually related to variables that measure the severity of respiratory and systemic process.

Full textAcute respiratory distress syndrome (ARDS) is an acute respiratory failure with a global incidence in Europe of 17.9 per 100,000 person-year. Although significant advances have been performed in supportive care of patients with ARDS, mortality remains high (40%) and survivors present persistent sequelae. An effective pharmacological therapy for this syndrome is not available yet. ARDS pathophysiology involves pulmonary activated coagulation and inflammation together with the breakdown of the alveolar-capillary barrier. This leads to proteinaceous edema, neutrophils infiltration into the alveolar compartment and the activation of macrophages towards a pro-inflammatory phenotype. Beneficial effects of anti-coagulants have been proved in pre-clinical models of acute lung injury (ALI) and in ARDS patients, although systemic bleeding offset its positive effects. Anti-coagulants could be effective for their anti-inflammatory activity in addition to their anti-coagulant properties. Moreover, given the cross talk of these pathways and their influence on permeability, anti-coagulants could also restore the alveolar-capillary barrier. Nebulization of anti-coagulants directly into the alveolar compartment might increase local efficacy and decrease the risk of systemic bleeding. The hypothesis of this thesis is that nebulized heparin and/or antithrombin (ATIII) limit the pro-inflammatory and pro-coagulant response in the lungs after ALI, also promoting the restoration of the alveolar-capillary barrier. The co-administration of both anti-coagulants directly into the lungs via nebulization produces a synergistic effect enhancing the properties of heparin and ATIII, reducing lung injury and avoiding the risk of systemic bleeding. As part of this thesis we are showing the results of the action of heparin or ATIII in specific primary human injured cell lung populations and the direct administration of heparin and/or ATIII into the lungs by nebulization in a rat model of ALI. Nebulized heparin and/or ATIII attenuated pulmonary inflammation and coagulation and did not produce systemic bleeding in the model of ALI. Treatment with nebulized heparin modulated alveolar macrophages through reducing TGF-β and NF-κB effectors and the coagulation pathway and decreased the recruitment of neutrophils into the alveolar space. Local administration of ATIII alone increased beneficial effects in coagulation, while combined ATIII and heparin had a higher impact reducing permeability and decreasing the infiltration of macrophages into the alveolar compartment. The translational action into humans of both anti-coagulants was also studied. In injured human cell lung populations isolated from lung biopsies, heparin diminished the expression of pro-inflammatory markers in alveolar macrophages and deactivated the NF-κB pathway in alveolar type II cells; decreasing the expression of its mediators and effectors. Also, ATIII decreased levels of pro-inflammatory mediators and increased levels of tight junctions in injured alveolar type II cells. The current studies prove that nebulized heparin and ATIII might be a potential treatment for ARDS, as they act in different pathways and processes of the pathophysiology of this syndrome. Local administration of anti-coagulants attenuates lung injury decreasing inflammation, coagulation and proving ameliorations on permeability without causing systemic bleeding.

Un estudio piloto." Tesis, Universidad de Chile, 2016. http://repositorio.uchile.cl/handle/2250/139895.
Full textIntroducción: varios estudios experimentales han mostrado que la ventilación mecánica puede inducir lesión pulmonar aún en pulmones previamente sanos, pero cuando estos presentan un síndrome de distrés respiratorio agudo de cualquier origen, parecen particularmente sensibles a los efectos nocivos de la ventilación mecánica. Por otra parte, factores de crecimiento angiogénicos como el factor de crecimiento endotelio vascular (VEGF) pueden modular la permeabilidad endotelial. Los procesos biológicos que median el aumento de la permeabilidad vascular posterior a un daño pulmonar inducido por la ventilación mecánica, y por ende el desarrollo de edema pulmonar, no son completamente conocidos. No existen estudios que hayan evaluado el impacto de la estrategia ventilatoria sobre los niveles de VEGF, ni su posible rol en el aumento de permeabilidad y el desarrollo de edema pulmonar. Objetivo: Determinar en un modelo de lesión pulmonar aguda, si comparado con animales sanos, existe alteración en los niveles de VEGF en plasma, tejido pulmonar y lavado broncoalveolar; si estos cambios se asocian a alteraciones de permeabilidad vascular, lesión y edema pulmonar; y si estas alteraciones pueden ser revertidas al emplear una estrategia ventilatoria ultraprotectora (volumen corriente 2 ml/kg de peso corporal) asociada a soporte vital extracorpóreo, comparado con una ventilación no protectora (volumen corriente 10 ml/kg de peso corporal). Resultados: no se observó diferencias en los niveles relativos de VEGF en el grupo de animales con lesión pulmonar aguda ventilados con una estrategia convencional y ultraprotectora más soporte vital extracorpóreo, en plasma al tiempo 0, 3 y 24 horas, y en el homogeneizado de tejido pulmonar, en comparación al grupo control (p<0.05). No se observó una asociación entre los niveles relativos de VEGF en el grupo de animales con lesión pulmonar aguda ventilados con una estrategia convencional y ultraprotectora más soporte vital extracorpóreo, en plasma (tiempo 0, 3 y 24 horas) y homogeneizado de tejido pulmonar, y los cambios en la concentración de proteínas en el lavado broncoalveolar, tasa peso húmedo/seco y daño pulmonar histológico (p<0.05). No se observó niveles relativos de VEGF, evaluados con la técnica de Western blot, en las muestras de lavado broncoalveolar. Conclusiones: la estrategia ventilatoria empleada no altera los niveles relativos del factor de crecimiento endotelio vascular en plasma y tejido pulmonar, en un modelo de cerdos con lesión pulmonar aguda inducida por lavados con solución salina repetidos y ventilación mecánica con alto volumen corriente. Además, los cambios observados en la permeabilidad vascular, daño y edema pulmonar no tienen una asociación con los niveles relativos del factor de crecimiento endotelio vascular en el plasma y tejido pulmonar. Sin embargo, existe un número importante de limitaciones técnicas que deben ser consideradas al momento de interpretar estos resultados, y que hacen necesario continuar investigando y desarrollando la metodología de trabajo para documentar resultados confiables, y que permitan un constructo teórico en relación a VEGF en este modelo de lesión pulmonar aguda.

Full textOur thesis objective was to study eicosanoids role on acute respiratory distress syndrome (ARDS) development by studying their plasmatic concentrations. Other objective was to evaluate if parenteral administration of an enriched 3 series polyunsaturated fatty acids (PUFA n-3) in the form of fish-oil and lowered linoleic acid (PUFA n-6) lipid emulsion can regulate eicosanoid synthesis in ARDS patients as well as its hemodynamics and gas exchange effects. Thesis is articulated as a publication compendium structured in three original articles. On our first study, in early ARDS stages we evaluate both systemic and mixed venous plasmatic eicosanoid levels in all enzymatic pathways (TXB2 and 6-Keto-PGF1α in COX pathway, and LTB4 in LO pathway). On our second study, we analyse eicosanoids in ARDS patients during administration of two different lipid emulsions, one PUFA n-6 enriched and the study´s emulsion (PUFA n-3 enriched and with less PUFA n-6). On our third study we focused on gas exchange and hemodynamic changes with the previous lipid emulsions in ARDS patients. Main results showed that eicosanoid plasmatic levels measured in early stage ARDS patients were superior to reference levels. Systemic TXB2, LTB4 and pulmonary-systemic LTB4 gradient correlated with hypoxemia severity. Pulmonary-systemic LTB4 gradient correlated with pulmonary severity score. LTB4 and TXB2 increased baseline plasmatic arterial levels, LTB4 increased venous mixed plasmatic levels and a higher pulmonary-systemic LTB4 gradient were associated with a worst outcome. In patients whom received PUFA n-6 enriched lipid emulsions, all eicosanoids measured levels, both systemic and venous mixed, were increased during emulsion perfusion with an erratic behaviour after the end (12 hours after finishing lipid emulsion). In patients treated with PUFA n-3 enriched emulsion and less PUFA n-6, all eicosanoids measured levels, both systemic and venous mixed, were decreased during study´s emulsion perfusion. Only LTB4 variation was statistically significant. After finishing emulsion´s administration, levels continued decreasing. Finally, we didn´t observe any significant variation neither in gas exchange nor in hemodynamics after both different emulsion´s administration. These results from our exposed studies lets us stablish that different lipid mediators play an important role in ARDS physiopathology with special emphasis on LTB4. We can also stablish that a parenteral administration of an PUFAn-3 enriched lipid emulsion in the form of fish oil and lowered linoleic acid (PUFA n-6) lipid emulsion can modulate crutial ARDS lipid mediator´s synthesis without hemodynamic or gas exchange short term modifications.
