The carbon dioxide laser; some possibilities in surgery

Acta chirurgica Belgica
R C VerschuerenJ Oldhoff

Abstract

The CO2 laser emits an infra red beam with a wavelength of 10,6 mu. Focussing this beam gives a tremendous energy density. The strong absorption of this wavelength allows tissue evaporation at the focal point of the beam. The first surgical application is the use of this laser as a light knife. Satisfying haemostasis can be obtained. Vessels with an internal diameter up to 0,5 mm being sealed, haemostatic cutting is possible. Even cortical bone can easily be cut with this instrument. The ability to vaporize tissues can be used for tumor destruction. Special attachments for endoscopic surgery are available. Experimental work in the rectum and on vocal cords has been done in our laboratory. The important problem in laser surgery is the necrosis on the edges. Investigations about the viability of the margins, showed that the width of the necrosis is in linear relationship with the rate of the exposure time. For an exposure of 1/10th of a second this width was about 130 mu, for an exposure of 6 seconds about 600 mu. After one year of experimental work with the CO2 laser we are convinced that this instrument might prove to be a reliable tool in surgery.

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.
