INTRODUCTION Identifying acute hypercapnic respiratory failure is crucial in the initial management of acute exacerbations of COPD. Guidelines recommend obtaining arterial blood samples but these are more difficult to obtain than venous. We assessed whether blood gas values derived from venous blood could replace arterial at initial assessment. METHODS Patients requiring hospital treatment fo...

BACKGROUND Arterial blood gases (ABGs) are often sampled incorrectly, leading to a 'mixed' or venous sample. Delays in analysis and air contamination are common. OBJECTIVES We measured the effects of these errors in patients with chronic obstructive pulmonary disease (COPD) exacerbations and controls. METHODS Arterial and venous samples were analyzed from 30 patients with COPD exacerbation ...

Background: The goal of fluid challenge (FC) is to increase cardiac output (CO) and oxygen delivery (DO2) (known as responders) correct tissue hypoxia. To optimize administration, during dependence consumption on (VO2/DO2 dependency) would hypoxia confirmed by an (VO2) after FC VO2 get more benefit from a reduction in Markers anaerobic metabolisms, such blood lactate concentration or the ratio ...

The aim of this study was to compare diagnostic value of high spatial resolution time-resolved magnetic resonance angiography with interleaved stochastic trajectory (TWIST) using Gadobutrol to Computed tomography angiography (CTA) for preoperative evaluation of lower extremity tumors.This prospective study was approved by the institutional review board. Fifty consecutive patients (31 men, 19 wo...

BACKGROUND The objective of this study was to examine the correlation between arterial blood gas (ABG) and peripheral venous blood gas (VBG) samples for all commonly used parameters in patients admitted to a medical intensive care unit (ICU). METHODS A single-center, prospective trial was carried out in a medical ICU in order to determine the level of correlation of ABG and peripheral VBG mea...

Thromboembolism is a rare complication of primary nephortic syndrome. Both venous and arterial thrombosis might occur in steroid responsive and steroid resistant nephrotic syndrome. This is the report of an infant with nephrotic syndrome and renovascular hypertension, complicated with asymptomatic intracardiac thrombus and managed appropriately with medical treatment.

SUMMARY BACKGROUND The true incidence of vascular injuries in Ghana is not known on account of low reporting. OBJECTIVE We performed a study aimed at reviewing the pattern of injuries to peripheral vessels, and also the pattern of referral, presentation and management of these injuries at the Korle-Bu Teaching Hospital, Accra. METHOD The study covered the period of January 1989 to March 200...

Arterio-Venous Fistulae (AVF) are regarded as the "gold standard" method of vascular access for patients with End-Stage Renal Disease (ESRD) who require haemodialysis. However, up to 60% of AVF do not mature, and hence fail, as a result of Intimal Hyperplasia (IH). Unphysiological flow and oxygen transport patterns, associated with the unnatural and often complex geometries of AVF, are believed...
