conclusions: the effects of propofol on hemodynamics and arterial oxygen pressure during one- or two-lung ventilation were not different from those of isoflurane. results: sixty patients (mean age = 4124.18 ± 18.63 years) were divided into two groups. the age and gender of the subjects were not statistically different between the two groups. in the propofol group, the arterial oxygen pressure d...

introduction: arterial stiffness is an important predictor of cardiovascular risk. several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...

effects of acute systemic hypoxia on the cardiovascular system (cys) and respiration of spontaneously breathing cats were studied in two conditions. 1): hypoxic air (6-8% 02 in n2) was given to the animal to induce systemic hypoxia for 20 minutes. hyperventilation at this condition lowered arterial c02 tension (pac02 hypocapnia). 2): in the second run, induction of hypocapnia was prevented by a...

base deficit is a non-respiratory indicator of acid base status. aim of this study is to assess relationship between the base deficit value in immediate post operative period of cabg and valvular heart disease with cardiopulmonary and in hospital outcome of patient. a total of 136 consecutive with cabg and valvular heart disease scheduled in study. 20 variables were determined during the pre-in...

arteritis due to strongylus vulgaris is a well-known cause of colic in horses and donkeys. the current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by s. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial o...

an elevated pulmonary artery pressure (pap) from any cause is associated with increased mortality, especially in cases of primary pulmonary arterial hypertension (pah). one of the many reasons behind a bad prognosis is the inherent difficulty in assessing right ventricular (rv) function with reproducible methods. intensive research involving the left heart has made it relatively easy to assess ...

effects of acute hypercapnia on the cardiovascular system (cys) were studied in the anesthetized cat. after surgery the animal was exposed to a gas mixture of 12% co2 and 25% o2 in nitrogen, and hypercapnia with low levels of arterial ph (pha) was produced for 20 minutes. in the second run the same level of hypercapnia was induced by ventilating the same cat from the above gas mixture but pha w...

although arterialovenous fistulae (avf) is considered to be vital for chronic kidney disease (ckd) patients, but they may cause complications and problems. for instance they may fail soon after their creation. the most important cause of failure in these cases is intrafistula thrombus formation. whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this study ...

introduction: one of the main complications of hemodialysis in patients with chronic renal failure is hypoxemia which is related to several factors including the type of filter. the aim of this study was to evaluate the hypoxemia levels in patients undergoing hemodialysis with focus on the type of filter. methods: in a crossover clinical trial, 29 patients from emodialysis ward of fatemieh hosp...
