2023
We present a protocol for using Fu's subcutaneous needling for knee osteoarthritis pain, which combines swaying movement and reperfusion approach techniques. This protocol has great potential for future applications in myofascial pain treatment and could enhance Fu's subcutaneous needling (FSN) manipulation skills.

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...

We standardized an abdominal adipose tissue biopsy using a non-diathermy method performed under local anesthesia. Three cases of excessive post-operation bleeding out of 115 operations (2.61%) occurred.We conclude that an abdominal adipose tissue surgical biopsy using a non-diathermy method can be safely applied to healthy men.

2013
Human tumor xenografts in immunodeficient mice are valuable tools to study cancer biology. Specific protocols to generate subcutaneous and intrahepatic xenografts from human hepatocellular carcinoma cells or tumor fragments are described. Liver regeneration induced by partial hepatectomy in recipient mice is presented as a strategy to facilitate intrahepatic engraftment.
FAQs
Gauge describes the needle’s thickness, while length determines how far it can extend through the skin layers. Together, these dimensions help clinicians position the tip within subcutaneous fat rather than stopping too shallowly or extending unnecessarily deep. Appropriate selection also contributes to patient comfort and supports consistent medication delivery for the intended treatment.
Insertion angle helps guide the needle through the epidermis and dermis into the subcutaneous layer. Injection volume also influences how comfortably and accurately medication can be delivered into that tissue. Considering both factors helps clinicians maintain correct placement, reduce tissue injury, and support reliable dosing rather than treating needle choice as the only determinant of injection quality.
Medication placed in subcutaneous fat can enter the circulation gradually, which distinguishes this route from approaches intended for more immediate delivery. Accurate positioning is therefore important: the needle must pass beyond the epidermis and dermis without extending into a deeper tissue target. This placement supports therapies designed to provide reliable absorption over time.
These goals depend on coordinating needle gauge, length, insertion angle, and injection volume rather than optimizing one feature in isolation. The selected combination should reach subcutaneous fat, accommodate the medication, and limit unnecessary tissue disturbance. Careful technique then helps preserve accurate placement and dependable dosing while making treatment more tolerable for the patient.
Clinicians should use a short, fine, sterile device selected for the medication and intended subcutaneous placement. The procedure requires directing the needle through the epidermis and dermis into the underlying fat, while accounting for gauge, length, angle, and volume. These decisions support accurate delivery, patient comfort, and reduced tissue injury during treatment.
The subcutaneous route is used for insulin, anticoagulants, vaccines, and other medications suitable for delivery into subcutaneous tissue. Its practical value extends beyond clinician-administered care because some treatments can be given safely by patients outside clinical settings. Appropriate device selection and technique remain important in either setting to maintain reliable dosing.
