objectives the purpose of this study was to evaluate the effects of normobaric hyperoxia on clinical neurological outcomes of patients with severe traumatic brain injuries. we used the glasgow outcome scale (gos), barthel index, and modified rankin scale (mrs) to measure the outcomes of patients with tbi. patients and methods sixty-eight consecutive patients with severe tbi (mean glasgow coma s...

aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...

Mn(TPP)Cl catalyzes cooxidation of olefin in the singlet oxygenation of sulfid. Mn(TPP)Cl is able to transfer an oxygen atom from a peroxidic intermediate generated in singlet oxygenation of sulfide to a metal ion affording metal 0x0 species which is responsible for epoxidation. This system leads to allcenes epoxidation such as styrene and cyclooctene. Epoxidation of cyclohexene produces cy...

background: because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. in this study we compared inhalation anesthesia with total intravenous anesthesia (tiva) for rigid bronchoscopy. method and materials: 30 patients aged 2-6 years were chosen divided on two same groups. anesthe...

To the editor, In response to: Assessment of oxygenation after balloon pulmonary angioplasty for patients with inoperable chronic thromboembolic hypertension. We read interest study by Matsuoka et al. [1] reporting on effects (BPA) tissue oxygenation. Despite an improvement in haemodynamics following BPA, authors conclude that oxygenation, exercise-induced desaturation (EID) and exertional dys...

abstract background: the aim of this study was to compare changes in pain, oxygenation, and ventilation following endotracheal suctioning with open and closed suctioning systems in post coronary artery bypass grafting (cabg) patients. materials and methods: 130 post cabg mechanically ventilated patients were randomly allocated to undergo either open (n = 75) or closed (n = 55) endotracheal suct...

background : since the use of high concentrations of oxygen in infants may lead to chronic lung problems, using proper methods of care in infants under mechanical ventilation is one of the most important measures in nicu. this study aimed to investigate the effects of prone and supine positions on oxygenation (spo 2 ) in premature infants under mechanical ventilation and comparing infants’ oxyg...
