Fast, accurate blood gas testing is a critical component to managing the post isolated coronary artery bypass (ISO-CAB) patient in the hospital intensive care unit/coronary care Unit (ICU/CCU). Post ISO-CAB patients are admitted to the ICU/CCU after surgery mechanically ventilated. Evidence-based medicine supports...

With increasing age, an unspecific rise of fibrin degradation product in blood is observed. Thus, the D-dimer test to rule out thromboembolic events has a high false positive rate in elderly patients. In 2010, Douma et al introduced a formula to adjust D-dimer cut-off values for age in outpatients >50 years: Age ×...

How do errors occur in the laboratory and what can we do to prevent errors? Any test can and will fail if incorrectly performed or operated under the wrong conditions. The role of the laboratory director is to determine those conditions and to understand test limitations in order to prevent laboratory errors....

Emergency Department (ED) overcrowding is becoming an increasingly international issue.  Although the problem is not only resolved by ED change management (but rather requires a system-wide solution recognizing the complex interdependencies of consumer expectations, human resources, information systems immaturity and...

Point of care (POC) testing has become an important part of nephrological care. In cases of acute renal failure, POC is indispensible in deciding the need for dialysis, but is also essential in the management of patients on regular dialysis. For example, hyperhydration, cardiovascular adverse events and inflammation...

Few studies have addressed the predictive value of C-reactive protein at different cutoff values in appendicitis. We have determined the cutoff values for C-reactive protein levels at different periods during clinical evolution of appendicitis and established their use to support the diagnosis of appendicitis. The...

Diagnosing heart failure (HF) in patients presenting in primary care is difficult. Clinical assessment of symptoms and signs has limited sensitivity and specificity. NT-proBNP determination has been proven to be useful and accurate for ruling out the diagnosis of systolic HF, and some have even proposed different...

Many authors contend that drawing of umbilical ABGs is a simple method to evaluate the condition of the neonate and ideally would be routinely done for all newborns [13]. Other authors disagree. Appropriate general principles guide clinicians when drawing and interpreting ABGs for all patients. The special needs of...

BACKGROUND: Hospitals in countries with public health systems have recently adopted organizational changes to improve efficiency and resource allocation, and reducing inappropriate hospitalizations has been established as an important goal, as well as avoiding or buffering overcrowding in Emergency Departments. AIMS: ...
