Abstract

This study was made to investigate the suitability of a modified laryngeal mask airway as an aid for fibreoptic endotracheal intubation in patients with a difficult airway. We used a laryngeal mask airway split lengthwise on its convex site, the incision going from a point corresponding to the teeth down to the base of the cuff. The cuff remains uncut. By this modification it is possible to ventilate an anaesthetised patient and to pass down a fibreoptic bronchoscope via splitting of the laryngeal mask airway into the trachea at the same time. An endotracheal tube of any diameter already mounted over the bronchoscope is then guided into the trachea. The feasibility of this technique was tested and haemodynamic reactions and changes of the parameters of respiration were recorded. This technique was used in 105 patients, 68 male and 37 female, mean age 34 years, when difficult intubation was expected or occurred. Blood pressure, pulse rate and peripheral oxygen saturation was recorded on arrival in the anaesthetic room, after induction of anaesthesia, during and after fibreoptic endotracheal intubation. The respiratory minute volume was measured after insertion of the laryngeal mask airway and during the course of fibreoptic intu...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.
