Sepsis and septic shock are are among the major causes of mortality in intensive care units. The lung and kidney are the organs most affected by sepsis. Evidence exists that lipid peroxidation and apoptosis may be responsible for the high mortality due to sepsis. Ischemic preconditioning (IP) is a method for the protection of tissues and organs against(More)
PURPOSE The aim of this study was to investigate the effects of mobilization on respiratory and hemodynamic parameters in critically ill obese patients. METHODS Critically ill obese patients (n = 31) were included in this retrospective study. Data were collected from patients' files and physiotherapy records of mobilization sessions. Heart rate (HR),(More)
BACKGROUND Ischemia and reperfusion of the skeletal muscle tissue may cause remote lung injury. We aimed to evaluate the protective effect of ischemic preconditioning (IP) on the lung during unilateral lower limb ischemia reperfusion (IR). METHODS Four groups of rats were used in this study: (i) the sham group (sham, n = 6) served as time controls, they(More)
In the present study, the effects of dexmedetomidine on secondary lung and kidney injuries were studied in the rat model of intra-abdominal sepsis by immunohistological and biochemical examinations. We measured serum creatinine, kidney tissue malondialdehide and plasma neutrophil gelatinase-associated lipocalin levels. In order to evaluate tissue injury we(More)
BACKGROUND Antithrombin III (AT III) is a serine protease inhibitor and the mechanism of its anti-inflammatory action is still not understood. In the present study, we aimed to investigate the anti-inflammatory action of AT III on lung injury in a rat model of sepsis. METHODS Three groups of animals were used in this controlled study: the sham-operated(More)
BACKGROUND Anti-inflammatory action of Antithrombin III (AT III) is still not well understood in ischemia/reperfusion (I/R) injury. In the present study, we aimed to investigate the anti-inflammatory action of AT III on remote lung and local skeletal muscle tissue injury in a rat model of bilateral lower limb I/R model. METHODS Bilateral lower limb(More)
Apneic oxygenation is an apnea testing method in the diagnosis of brain death. In this method, oxygen (O2) is delivered into the trachea via an O2 catheter (O2C). However, barotrauma may develop during O2 insufflation into the trachea. Oxygen catheter diameters, O2 catheter tip position in the trachea, and O2 flow rate have been proposed as causes of(More)
OBJECTIVE In this study, two enteral nutrition protocols with different gastric residual volumes (GRVs) and different monitoring intervals were compared with respect to gastrointestinal intolerance findings in intensive care unit (ICU) patients. METHODS The study was carried out prospectively in 60 patients in the anaesthesiology and reanimation ICU under(More)
Serotonin syndrome occurs with selective serotonin reuptake inhibitors, opioids, and other serotonergic agents. We describe a possible serotonin syndrome related to intrathecal fentanyl in a patient taking multiple drugs and substances such as ergot alkaloids, marijuana, methylenedioxy-N-methylamphetamine, and ephedrine.
