Circulating concentrations of the hormone brain natriuretic peptide (BNP) and its precursor molecule, NT-proBNP are increased in those with heart failure. This has allowed a now established role for serum BNP and NT-proBNP testing in the investigation of patients presenting with shortness of breath, a cardinal symptom ...

Acute pancreatitis, i.e. acute inflammation of the pancreas, causes sudden onset of severe upper abdominal pain often radiating to the back. Other symptoms include vomiting, constipation and pyrexia. Two main causes - alcohol abuse and gall stone disease – account for the majority (~80 %) of cases. The condition has a ...

Barnsley Emergency Department (ED), which recruited patients into the RATPAC trial, initiated a point-of-care (POC) pathway for low-risk chest pain patients from December 2011. All patients who underwent POC testing for chest pain between December 2011 and July 2012 were identified. Patient notes were then examined...

The pH, base excess and pCO₂ (acid-base status) of arterial blood flowing through the umbilical cord provides valuable objective evidence of the metabolic condition of neonates at the moment of birth; a notion that has assured a role for the blood gas analyzer in hospital delivery suites in cases of suspected fetal...

In the past years, emergency rooms (ER) all over Germany, especially those of maximum-care hospitals, have been faced with an increasing number of patients. This is caused by a variety of factors, including demographic changes, inflexible ambulant services and an overreaching demand for healthcare services. ER...

Since the inception of blood gas analysis, heparin has been the anticoagulant of choice for preparation of samples. Historically, syringes used to collect arterial blood for gas analysis were prepared ”in house” by aspirating a small volume of liquid heparin (LH) and then expelling it. The thin film of liquid heparin...

Those who have been resuscitated from cardiac arrest may benefit from mechanical-ventilation strategies aimed at maintaining pCO₂ above the normal (reference) range, 35-45 mmHg (4.7-6.0 kPa). This is the headline finding of recently published research from the FINNRESCUI study group, a collaboration of Finnish...

Umbilical-cord blood gas analysis provides objective evidence of the metabolic status of neonates at the time of delivery. Perinatal metabolic acidosis is indicative of hypoxia (sometimes the result of asphyxia during birth) and associated risk of permanent brain damage.  A recently published study sought to assess...

Point-of-care testing (POCT) for key laboratory variables may help clinicians assess the level of acuteness and the level of care necessary in the management of deteriorating ward patients. We used a multibiomarker POCT panel including B-type natriuretic peptide (BNP), D-dimer, myoglobin (Myo), creatine kinase MB...

The management at the emergency department of patients presenting with symptoms of chest pain and/or acute dyspnea accounts for a substantial proportion of emergency care resources. In the work-up of these patients the blood measurements of cardiac troponins and brain natriuretic peptides are recommended by current...
