Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...

totally implantable venous access devices (tivad) or implantable catheter ports are devices which can be implanted subcutaneously. they enable prolonged and repeated access to the vascular system, into the peritoneal cavity or intravertebral space. this device is particularly useful for repeated medical injection, for blood sampling or transfusion of blood and blood derivatives and for total pa...

diagnosis of cardiac tamponade has been mainly based on clinical features and echocardiography. however, ct may be an initial tool for the evaluation of cardiac tamponade because cutting edge ct is increasingly being installed in the emergency room, and presentation of cardiac tamponade can be nonspecific. importantly, ct has better spatial resolution compared with echocardiography. thus, ident...

results the incidence of diagnosed thrombo-embolic complication was 32 of 1,153 admitted patients (2.8%; 95% confidence interval: 1.9 to 3.9) with a median interval of 14 days after anti-tb treatment initiation. the incidence of dvt and pte was 2% and 1%, respectively. thrombo-embolic events and dvt were more common in men than in women: 4.2% versus 1.3% (p = 0.003) and 3.5% versus 0.4%, respec...

introduction:the assessment of intravascular volume in severely traumatized patients or patients admitted in icu is very essential. at present the accurate method for estimating the intravascular volume requirement is by measuring the cvp which is an invasive method. the measurement of ivc diameter by ultrasound has been suggested as an easily available and simple method for measuring the intra...

superior vena cava (svc) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. in majority of the cases, svc syndrome occurs due to mechanical obstruction of the svc by extraluminal compression with primary intrathoracic malignancies. however, intraluminal obstruction due to thrombosis can also produce symptoms and signs of svc synd...
