The use of epidural morphine in patients undergoing total knee arthroplasty

Abstract

Sixty-six patients undergoing total knee arthroplasty were offered epidural morphine as a method of postoperative analgesia. Of the 66 patients, 50 completed the minimum protocol of 3 days in a special epidural monitoring unit and were thus available for study. In this study group, 86% stated that they obtained 75-100% relief of pain with each epidural injection. Greater than 90% of the patients rated the overall experience with epidural analgesia as excellent or good. Ninety percent stated that they would choose epidural morphine analgesia again if given the choice. Nausea and vomiting were the most common adverse effects, occurring in 34%. One patient experienced respiratory depression, which was reversed with Narcan. The most frequent complaint related to the procedure itself was the use of an apnea monitor; 18% of the patients considered this monitoring device intolerable. The progress of total knee arthroplasties in the epidural unit was monitored by range of motion achieved. At 72 hours the average motion was 10 degrees-87 degrees and at the end of the hospital stay was 6 degrees-98 degrees. The total hospital bill for epidural morphine analgesic patients was $469 more than for a conventional arthroplasty patient, though ...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.
