Key points † Mechanical ventilation can have adverse effects on pulmonary function by several distinct mechanisms. † Patients undergoing one-lung ventilation or cardiopulmonary bypass are at increased risk of developing acute lung injury (ALI). † Protective ventilatory strategies may prevent or reduce ALI. † There is a lack of randomized controlled trials to guide optimal intra-operative ventil...

INTRODUCTION Experimental work provides insight into potential lung protective strategies. The objective of this study was to evaluate markers of ventilator-induced lung injury after two different ventilation approaches: (1) a "conventional" lung-protective strategy (volume control (VC) with low tidal volume, positive end-expiratory pressure (PEEP) and paralysis), (2) a physiological approach w...

Background: Paraquat (PQ), an herbicide, is a very poisonous compound for both humans and animals. This study was conducted to examine the protective effect of the Coenzyme Q10 (CoQ10) in newborn rats from pregnant rats pre-treated with PQ. Methods: The experiments were conducted on 25 rats, divided in five groups randomly and equally: 1 - Control Group received normal saline (0.1ml/day); 2...

widespread use of herbal drugs because of their protective effects on different organs toxicity has been shown in many studies. these protective effects have been illustrated in the fields of nephrotoxicity, hepatotoxicity, viral hepatitis, cancer, in vitro fertilization, neurotoxicity, depression, lung diseases, prostate diseases etc. silymarin has cytoprotection activities due to its antioxid...

BACKGROUND Mechanical ventilation with positive end expiratory pressure and low tidal volume, i.e. protective ventilation, is recommended in patients with acute respiratory distress syndrome. However, the effect of protective ventilation on bacterial growth during early pneumonia in non-injured lungs is not extensively studied. The main objectives were to compare two different ventilator settin...

INTRODUCTION Leukocyte infiltration is central to the development of acute lung injury, but it is not known how mechanical ventilation strategy alters the distribution or activation of inflammatory cells. We explored how protective (vs. injurious) ventilation alters the magnitude and distribution of lung leukocyte activation following systemic endotoxin administration. METHODS Anesthetized sh...

INTRODUCTION Independent lung ventilation is a form of protective ventilation strategy used in adult asymmetric acute lung injury, where the application of conventional mechanical ventilation can produce ventilator-induced lung injury and ventilation-perfusion mismatch. Only a few experiences have been published on the use of independent lung ventilation in newborn patients. CASE PRESENTATION...
