ABGs and arterial lines: the relationship to unnecessarily drawn arterial blood gas samples

Abstract

Arterial blood gas measurements (ABGs) are the most common tests ordered in an ICU. ABG utilization in a surgical ICU over a 1-year period (September 1, 1987-October 31, 1988) was evaluated to identify factors that might help reduce overutilization. A total of 842 admissions comprising 2,381 patient days were reviewed. ABGs were the most commonly ordered test (mean of 4.8/patient/day). Patients with arterial lines (A-lines) had more ABGs drawn than those who did not regardless of the value of PaO2 (p less than 0.01), PaCO2 (p less than 0.01 except for PaCO2 greater than 55), APACHE II score (p less than 0.01), use of ventilators (p less than 0.01), pulse oximeters (p less than 0.01), or a combination of the last two (p less than 0.01). Multivariate analysis demonstrated that the presence of an A-line was the most powerful predictor of the number of ABGs drawn per patient (p less than 0.0001) independent of all other measures of the patient's clinical status such as the use of ventilators, oximeters, and values of PaO2, PaCO2, or the APACHE II score. This suggests that ABGs are being drawn unnecessarily simply because of the presence of an A-line. To reduce the number of ABGs drawn, a policy for specific indications for placemen...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
