Background: Arterial catheters are frequently needed to optimize the intensive care in sick newborn. Umbilical Catheters (UAC) is more popular than peripheral arterial catheterization. They utilized provide continuous accurate blood pressure monitoring, frequent assessment of gas exchange efficiency, sampling and rarely for transfusion. may be used emergencies infuse fluids or medications absen...

A new continuous noninvasive blood pressure measurement device, the T-Line Tensymeter TL100 (Tensys Medical Inc., San Diego, CA, USA) which enables avoidance of arterial cannulation has been developed. We compared the values obtained using the T-Line values to simultaneous arterial line measurements in patients undergoing general anaesthesia with induced hypotension. Twenty-five patients, aged ...

oxygen is an essential part of the most important metabolic pathways in aerobic organisms. oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. increasing intra-abdominal pressure (iap) has been shown to reduce liver b...

BACKGROUND: Diabetic ketoacidosis (DKA) is a life-threatening endocrine emergency, traditionally requiring arterial blood gas (ABG) analysis for diagnosis and monitoring. The aim of our study was to assess the comparability of arterial and venous blood samples for pH and bicarbonate measurements in patients with DKA. MATERIALS AND METHODS: Prospective, observational study of patients with suspe...

We determined the effect of intravenous and renal intra-arterial infusion of dopamine on the distribution of intracortical blood flow in kidneys of anesthetized dogs. Total renal and renal intracortical blood flows in dogs receiving dopamine intravenously were quantified by the radioactive microsphere technique with reference sampling. In dogs receiving dopamine by renal intra-arterial infusion...

Six Holstein steers (381 +/- 11 kg BW; mean +/- SE) surgically fitted with hepatic portal (n = 6), hepatic venous (n = 4), mesenteric venous, and arterial catheters were used in a replicated crossover design experiment to evaluate the influence of monensin addition to an alfalfa hay diet on net portal and hepatic nutrient flux. Steers were fed 6.5 kg of DM/d in 12 portions using automatic feede...

Arterial Spin Labeling (ASL) is a noninvasive perfusion technique which allows the absolute quantification of Cerebral Blood Flow (CBF). The perfusion is obtained from the difference between images with and without magnetic spin labeling of the arterial blood and the captured signal is around 0.5-2% of the magnitude of the labeling images, so the noise is one of the main problems for further da...

OBJECTIVE Atrial natriuretic peptide (ANP) regulates arterial blood pressure. In addition, ANP has recently been shown to promote human adipose tissue lipolysis through cGMP-mediated hormone-sensitive lipase activation. We hypothesized that ANP increases postprandial free fatty acid (FFA) availability and energy expenditure while decreasing arterial blood pressure. RESEARCH DESIGN AND METHODS...
