Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA For unstable patients requiring urgent administration of medications, fluids, or blood products, establishing vascular access quickly is essential. However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A tension pneumothorax is a life-threatening situation in which excess air is introduced into the pleural space surrounding the lung, either through trauma to the chest cavity or as a spontaneous leak of air from the lung itself. Air trapped within the pleural space causes separation of the lung from the chest wall, disrupting normal breathing mechanisms. Pneumothorax may be small without...

This protocol describes the assembly of a pneumatic system for the delivery of pressurized air to a needle during the process of needle beveling. The protocol further describes the beveling process for creating sharp microinjection needles and how to gauge the relative opening size of the needle.
FAQs
Its effects can extend from peripheral nerve endings into signaling pathways within the spinal cord and brain. Local tissue activation provides sensory input that may be processed centrally and influence physiological responses. This multilevel action helps explain why the consequences of stimulation are not limited to the tissue immediately surrounding the needle.
These variables determine which tissues and sensory pathways receive input and how strongly or persistently they are activated. A change in location may alter the targeted tissue, while depth can affect the structures reached. Manipulation pattern also changes the sensory signal, so outcomes depend on the specific stimulation conditions rather than needle insertion alone.
Both approaches use needles as the means of targeted stimulation, but they represent different ways of applying that intervention. Acupuncture may involve insertion and controlled manipulation, whereas electroacupuncture incorporates an electrical stimulation pattern. This distinction is important when comparing studies because the type and delivery of stimulation can influence the sensory input being investigated.
A typical application begins by selecting a target location, inserting a fine needle, and controlling its depth and manipulation. The practitioner or investigator then applies the intended stimulation pattern and observes the resulting response. These steps make the intervention adjustable while preserving a defined connection between the targeted tissue, sensory input, and clinical or experimental outcome.
Medical applications described for this technique include pain management, symptom relief, and functional rehabilitation. Clinicians may consider it when targeted sensory input is relevant to the intended therapeutic approach. Researchers also use these applications to examine whether activating somatic sensory pathways can modify physiological responses associated with symptoms or functional changes.
Studies can examine symptom relief, changes relevant to functional rehabilitation, and physiological responses produced by somatic sensory input. They may also compare how location, depth, or stimulation pattern relates to observed effects. This makes the technique useful both as a medical intervention under investigation and as a model for studying communication between peripheral tissues, the spinal cord, and the brain.
