Ultrasound-Guided Percutaneous Carpal Tunnel Release for Treatment of Carpal Tunnel Syndrome

January 17, 2019 Medical Technology Directory

Health Problem: Carpal tunnel syndrome (CTS) is a compression neuropathy of the median nerve at the wrist. It is characterized by increased pressure within the carpal tunnel and decreased function of the nerve. The estimated prevalence of CTS is 3.1% to 7.8% among adult workers, with higher prevalence among female and older-age workers. Technology Description: Surgery for CTS is referred to as carpal tunnel release, which involves decompression of the carpal tunnel by cutting through the ligament pressing down on the carpal tunnel. This report focuses on percutaneous carpal tunnel release (PCTR) for CTS. PCTR combines ultrasound guidance with minimal incisions....

Conventional Corneal Collagen Cross-Linking for Treatment of LASIK-Related Ectasia

December 27, 2018 Medical Technology Directory

Health Problem: Laser in situ keratomileusis (LASIK) is a refractive surgery procedure that reshapes the surface of the cornea with an excimer laser to focus visual images directly onto the retina and improve visual acuity. LASIK may disrupt the cornea. Post-LASIK corneal ectasia (also called keratectasia or keratoectasia) is a serious side effect that involves keratoconus-like progressive thinning and steepening of the central and inferior portions of the cornea. Technology Description: Corneal cross-linking (CXL) uses a combination of riboflavin (vitamin B2) eye drops with ultraviolet A (UVA) radiation to trigger a photochemical reaction that changes the cross-links between and within collagen...

Spinal Cord Stimulation for Relief of Neuropathic Pain

December 21, 2018 Medical Technology Directory

Health Problem: Neuropathic pain is defined as pain that is caused by a lesion or disease of the somatosensory system and is distinct from other pain conditions. The transmission of sensory information in the peripheral and central nervous systems can be profoundly impacted by these deleterious factors and result in perception of painful sensations generated by the nervous system itself. Prevalence estimates of neuropathic pain range from 1% to 17.9% based on American, European, and Asian studies. Technology Description: Spinal cord stimulation (SCS) is achieved through the implantation of a stimulator device and electrodes near the spine. A subcutaneous pulse generator...

Multiplex Molecular Panels for Diagnosis of Gastrointestinal Infection

December 18, 2018 Medical Technology Directory

Health Problem: Infectious gastroenteritis is a significant global health concern characterized by diarrhea, vomiting, and other symptoms; severe cases can lead to life-threatening dehydration. Causes include infections with bacteria (e.g., Clostridium difficile, Escherichia coli, Shigella), viruses (e.g., norovirus, rotavirus), or parasites (e.g., Cryptosporidium, Giardia). In the United States, there were nearly half a million emergency department visits associated with infectious gastroenteritis in 1 year, 39% of which led to hospitalization. Technology Description: Multiplex molecular panels allow for the qualitative detection of nucleic acid from multiple viral, parasitic, and bacterial pathogens in stool samples collected from patients with symptoms of gastroenteritis or...

Comparative Effectiveness Review of Antimicrobial Central Line Dressings for the Prevention of Central Line-Associated Bloodstream Infections

December 17, 2018 Medical Technology Directory

Health Problem: Intravenous catheters provide essential venous access when treating patients who are acutely or chronically ill, but their use also increases the risk of complications such as central line-associated bloodstream infections (CLABSIs). CLABSIs occur when microorganisms gain access to the bloodstream via 1 of several different routes: catheter hub contamination, catheter insertion-site colonization, contaminated infusate, and/or hematogenous seeding. Patients who develop a CLABSI have poorer health outcomes costing billions of dollars in added healthcare costs in the U.S. annually and contributing to thousands of patient deaths. Technology Description: Central venous catheters (CVCs) are implantable synthetic catheters used to access a...
