BACKGROUND Different additives have been used to prolong regional blockade. We designed a prospective, randomized, double-blind, controlled clinical trial to evaluate the effect of dexamethasone added to bupivacaine-fentanyl on the duration of postoperative analgesia via epidural catheterization. METHODS Seventy two adult patients scheduled for elective(More)
INTRODUCTION The main purpose of emergency department (ED) management for renal colic is prompt pain relief. The present study aimed to compare the analgesic effects of intravenus (IV) ketofol with morphine in management of ketorolac persistent renal colic. METHODS This study is a single blind randomized, clinical trial, on patients who were presented to(More)
Effects of different doses of adenosine receptor agonists and antagonists on naloxone-induced jumping and diarrhea in morphine-dependent mice were studied. The adenosine A1 receptor agonists, N6-cyclohexyladenosine (CHA: 0.1, 0.25 and 0.5 mg kg(-1)) and R-isomer of N6-phenylisopropyladenosine (R-PIA: 0.1, 0.3 and 1 mg kg(-1)), decreased jumping and diarrhea(More)
INTRODUCTION Headache is the most common neurologic symptom among referees to the emergency department (ED), while the best treatment has not yet been found. Therefore, in the present study pain relief effects of metoclopramide and acetaminophen were compared in patients suffered acute primary headache. METHODS This study was a double-blind randomized(More)
BACKGROUND Arrhythmia is a common complication after heart surgery and is a major source of morbidity and mortality. AIMS This study aimed to study the effect of magnesium sulfate (MgSO4) for reduction of postcardiac surgery arrhythmia. SETTING AND DESIGN This study is performed in the cardiac operating room and Intensive Care Unit (ICU) of Shahid(More)
INTRODUCTION Acute renal dysfunction is a common complication of cardiac surgery. Furosemide is used in prevention, or treatment, of acute renal dysfunction. This study was conducted to evaluate the protective effects of intra- and early postoperative furosemide infusion on preventing acute renal dysfunction in elective adult cardiac surgery. METHODS(More)
BACKGROUND QT dispersion (QTd) is equal to longer QTc minus shorter QTc measured by 12-lead electrocardiogram (ECG). QTd reflects inhomogeneity in repolarization of ventricular myocardium and because of easy and fast measurement of QTd, it can be used to predict high-risk patients for dysrhythmia after Acute Myocardial Infarction (AMI). OBJECTIVES This(More)
INTRODUCTION The correlation of central venous pressure (CVP) with inferior vena cava (IVC) sonographic diameter has been reported in several studies. However, few studies have attempted to find the best anatomic location of measurement. Therefore, the purpose of this study was determining the best anatomic location to find precise correlation between CVP(More)
INTRODUCTION Being a unique diagnostic technique, transesophageal echocardiography (TEE) has influenced many different aspects of cardiac surgery including valve repair surgery. The cost-effectiveness of this method however is questioned considering the conditions of every region and country. In this study we aimed at answering the question if utilizing TEE(More)
