MRI-compatible audio/visual system: impact on pediatric sedation

Pediatric Radiology
R K Harned, J D Strain

Abstract

While sedation is necessary for much pediatric imaging, there are new alternatives that may help patients hold still without medication. We examined the effect of an audio/visual system consisting of video goggles and earphones on the need for sedation during magnetic resonance imaging (MRI). All MRI examinations from May 1999 to October 1999 performed after installation of the MRVision 2000 (Resonance Technology, Inc.) were compared to the same 6-month period in 1998. Imaging and sedation protocols remained constant. Data collected included: patient age, type of examination, use of intravenous contrast enhancement, and need for sedation. The average supply charge and nursing cost per sedated patient were calculated. The 955 patients from 1998 and 1,112 patients from 1999 were similar in demographics and examination distribution. There was an overall reduction in the percent of patients requiring sedation in the group using the video goggle system from 49 to 40% (P < 0.001). There was no significant change for 0-2 years (P = 0.805), but there was a reduction from 53 to 40% for age 3-10 years (P < 0.001) and 16 to 8% for those older than 10 years (P < 0.001). There was a 17% decrease in MRI room time for those patients whose exa...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.
