materials and methods in a double blind randomized trial study, 100 patients undergoing elective cardiac surgery were randomized to using heparinized (n = 50) or non-heparinized (normal) saline flush (n = 50) to maintain patency of arterial catheter after operation. indwelling arterial catheters were checked daily for acceptable arterial waveform for three days as primary outcome measures. resu...

This paper examines the time course of changes in plasma electrolyte and acid-base composition in response to NaHCO3 and KHCO3 ingestion. It was hypothesized that skeletal muscle is involved in the correction of the ensuing plasma disturbance by exchanging ions, gasses, and fluids between cells and extracellular fluids. Five male subjects, with catheters in a brachial artery and antecubital vei...

in order to examine the hypothesis of this research, an accidental sample of 122 students have been appointed from among the community of female students who were studying at the last year of primary school in isfahan . the sample was divided into four groups, cognitive group, behavioral group, cognitive- behavioral group and control group. the impacts of independent variables have been assesse...

The role of nucleus tractus solitarius (NTS) in cardiovascular system regulation is controversial. On the other hand, the problem of hypertension in diabetic animals is the subject of many research programs. The aim of present study was to determine whether inactivation of NTS could affect blood pressure and heart rate in diabetic rats. To this end, stereptozotocin induced diabetic rats were an...

Background:  Patients undergoing cemented hip hemiarthroplasty may develop bone cement implantation syndrome (BCIS) which is a leading cause of intraoperative complications. The purpose of this study was to evaluate cardiovascular changes during cemented hip hemiarthroplasty in elderly patients.   Methods:  Cemented hip hemiarthroplasty was performed on 72 patients with femoral neck fracture. A...

In children, the most common cause of an elevated anion gap (AG) with ketonemia, ketonuria, hyperglycemia, and glycosuria is diabetic ketoacidosis. However, when the clinical history is not clear, other causes must be considered. A 9-month-old girl was transferred to our pediatric intensive care unit (PICU) because of severe metabolic acidosis. On admission, she presented with Kussmaul breathin...

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 ...
