2023
A reliable and reproducible approach for the insertion and maintenance of a tunneled Hickman catheter for long-term vascular access in swine is described. Placement of a central venous catheter allows for convenient daily sampling of whole blood from awake animals and intravenous administration of medication and fluids.

Here we explore contralateral tactile masking between the forearms in which tactile detection thresholds are modulated by vibration applied to a remote site. The details of which remote sites have an effect can tell us about how the body is represented in the brain.

Muscles that Move the Forearm

2024
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints. Forearm Flexors The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

FAQs
The vessel type determines the clinical purpose of the access. Peripheral venous placement commonly supports routine delivery of fluids, medications, or contrast, while arterial placement can support blood-gas sampling and continuous blood-pressure monitoring. Distinguishing these roles helps clinicians select an access approach that matches the intended treatment, measurement, or specimen collection.
Selecting a suitable vein or artery supports reliable device placement and helps limit preventable harm. The overview identifies infiltration, infection, bleeding, and nerve or tissue injury as important complications. Careful selection therefore contributes not only to access success but also to safer delivery, monitoring, or sampling throughout the clinical procedure.
Blood return provides confirmation that the needle or catheter has entered the intended blood vessel. This check helps clinicians assess placement before using the access for fluids, medications, contrast, or sampling. After confirmation, securing the device helps maintain its position and reduces the chance that movement will compromise the access site.
Aseptic skin preparation is a central procedural condition because the device crosses the skin barrier into a blood vessel. Clinicians also need to identify an appropriate vessel, advance the needle or catheter, confirm blood return, and secure the site. Together, these steps support reliable access while addressing infection, bleeding, and tissue-injury risks.
Venous access is generally chosen when the clinical goal is routine administration of fluids, medications, or contrast, or when blood sampling is required without the monitoring role associated with an artery. Arterial access is more specifically relevant when clinicians need blood-gas samples or continuous blood-pressure monitoring, so the intended use guides vessel selection.
Secure placement and appropriate vessel selection are used to reduce complications at the access site. The relevant risks include infiltration, infection, bleeding, and injury to nearby nerves or tissue. Preventing these outcomes depends on combining aseptic preparation with confirmation of blood return and stabilization of the needle or catheter after placement.
