Premedication with meperidine and diazepam for upper gastrointestinal endoscopy precludes the need for topical anesthesia

Gastrointestinal Endoscopy
D S Cantor, E T Baldridge

Abstract

The authors conducted a prospective study in 90 patients undergoing upper endoscopic examination under sedation to determine whether there was any beneficial effect in anesthetizing the pharynx with topical anesthesia. These patients were divided into three groups of 30 patients. Group A received 39 ml of viscous lidocaine gargle (2%) diluted with 15 ml of tap water. Group B received the placebo. Group C received neither viscous lidocaine nor placebo. All patients received intravenous meperidine and diazepam titrated to produce adequate sedation for upper endoscopy. It was demonstrated that the undesirable effects of upper endoscopy, that is, gagging, sore throat, and dysphagia, did not differ significantly in any of the three study groups as evaluated by either the patients or the endoscopist. Only two patients complained that the procedure was mildly unpleasant. The authors conclude that the practice of anesthetizing the pharynx in patients receiving sedation for upper endoscopy should be abandoned since anesthesia of the pharynx is not exempt from morbidity and mortality as well as being time-consuming and expensive.

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.
