because of significant reduction of rupture rate and increase in the patient’s life expectancy, elective surgical treatment in patients with abdominal aortic aneurysm has been widely accepted. the present article aims at assessing the postoperative complications and mortality rate in patients who had been submitted to elective surgery for abdominal aortic aneurysms. this is a retrospective stud...

background : the use of antibiotic prior to surgery is widely accepted. the who has recommended the use of atc/ddd (anatomical therapeutic chemical / defined daily dose) for the analysis of drug utilization.the aims of the present study are 1) to analyze the assessment of prophylactic antibiotic usage prior to surgery, 2) to assess the drug administration based on antibiograms and 3) to compare...

Atrial fibrillation (AF) is the most common arrhythmia after cardiothoracic surgery. AF following coronary artery bypass graft (CABG) is associated with an increase in morbidity, mortality, hemodynamic instability, thromboembolic events, severity of heart failure and ICU and hospital stay. Corticosteroids have a variety of beneficial effects on recovery after elective surgery. This study was de...

BACKGROUND Atrial fibrillation (AF) after coronary artery bypass grafting (CABG) is still the most common postoperative arrhythmic complication. Previous studies report that patients undergoing preoperative statin therapy had a lower incidence of postoperative AF. This study aimed to assess the effect of preoperative atorvastatin therapy on preventing AF following off-pump CABG in a randomized,...

PURPOSE To compare cardiac function assessed by intraoperative transesophageal echocardiography in patients undergoing cardiac revascularization with or without cardiopulmonary bypass. MATERIAL AND METHODS Forty-one patients scheduled for elective, isolated cardiac revascularization (21 on-pump and 20 off-pump) were prospectively analyzed. Patients were matched for demographic (age and gender...

BACKGROUND The ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e') correlates with left ventricular (LV) filling pressure. In particular, an E/e' ratio more than 15 is an excellent predictor of increased LV filling pressure. The authors evaluated the prognostic implications of preoperative estimated LV filling pressure, assessed by E/e' ratio, in pa...

conclusions most cases of splenectomy in our center caused by trauma, and among the different types of trauma, blunt trauma is the dominant cause. road traffic accidents, in particular motor vehicle accidents, especially motorbike injures, are the most frequent cause of splenectomy. due to the instability of trauma patients, a mortality rate of 8% seems to be reasonable for splenectomy. rnwe re...

objective: this study assessed the influence of maternal request on elective cesarean rate and related factors in maternity hospitals in tehran. materials and method: this cross sectional descriptive analytic study was performed via a two-step random sampling technique, using data from 824 pregnant women who attended the maternity hospitals in tehran in 2001. a questionnaire covering past and p...

This paper develops a two-stage planning procedure for master planning of elective and emergency patients while allocating at best the available hospital resources. Four types of resources are considered: operating theatre, beds in the medium and in the intensive care units, and nursing hours in the intensive care unit. A tactical plan is obtained by minimizing the deviations of the resources c...

conclusions intravenous magnesium sulfate with dose of 15 mg/kg could not prevent laryngospasm and coughing after removal of the endotracheal tube in patients undergoing adenotonsillectomy; however, it reduced coughing and laryngospasm in the magnesium sulfate group compared with the control group. results laryngospasm was not found in the magnesium sulfate group; however, its incidencewas5.7% ...
