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...
background: long surgery causes hypothermia and increased bleeding and can increase the arterial blood lactate levels during anesthesia. it causes cellular hypoxia and its complications. considering the core temperature of the patient during surgery it can prevent hypoxia. this study aimed to compare the effects of different temperatures on the core temperature and the concentrations of lactate...
background pain management with the use of sedatives and analgesics has several advantages and few complications or side effects. objectives in this study, we planned to evaluate the effects of pain control on oxygen saturation independent of other factors, such previous cardio-pulmonary conditions or respiratory rate. patients and methods sixty-seven adult patients with direct trauma to extrem...
a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...
BACKGROUND Arterial blood gas (ABG) analysis is useful in evaluation of the clinical condition of critically ill patients; however, arterial puncture or insertion of an arterial catheter may cause many complications. The aim of this study was to determine whether venous blood gas (VBG) values can be used as an alternative to arterial blood gas measurements in patients under mechanical ventilati...

Aim and Background: Arterial tourniquets are used widely for extremity orthopedic surgeries with regional or general anesthesia to reduce blood loss, but the harmful effect of ischemia and reperfusion is not clear yet. Materials and Methods: In this clinical trial 40 patients scheduled for lower extremity surgery with pneumatic tourniquet were randomized into 2 groups: a remote ischemi...
a significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. the aim of study is to examine the relationship between peak expiratory flow rate (pefr) before bronchoscopy and oxygen desaturation during bronchoscopy. measurement of pefr (% predicted) performed...
Introduction : Nowadays in many countries “massage” is considered as an important part of nursing care and in many clinical situations it is used as complementary treatment for stress reduction. This study with the goal of comparing of reflexive and stroke massages on physiologic indices in patients with MI was performed. Materials and Methods: This clinical trial was performed in 2012 on...
