Wedge NC Single-Strand Serrated Coronary Balloon Dilatation Catheter

New product highlights: This device has obtained CE certification, features high-pressure resistance, and is equipped with a nickel‑titanium guidewire on its surface. During balloon expansion, it concentrates stress more effectively on the vessel wall, making lesion dilation easier. Its unique scored balloon incorporates a nickel‑titanium scoring wire that enables full balloon expansion at lower pressures, maximizing lesion dissection and delivering superior results in treating calcified lesions. It is particularly well suited for pre‑dilation prior to drug‑eluting balloon implantation, facilitating rapid and thorough drug penetration into the vessel wall. The product exhibits excellent high‑pressure non‑compliance and boasts a higher rated burst pressure than comparable products on the market. Its patented balloon‑folding technology ensures nickel…

Do you feel the same way about inhalational anesthesia?

Inhalation anesthesia in animals refers to an anesthetic technique in which anesthetic agents are administered via the respiratory tract, thereby suppressing the central nervous system and inducing temporary loss of consciousness without eliciting systemic pain. It is also the primary method of general anesthesia. The depth of anesthesia correlates with the distribution of the drug within brain tissue; as the agent is eliminated from or metabolized in the body, the animal gradually regains consciousness without any lasting sequelae.

A Study on the Application of the Echo-Enhanced Needle in Ultrasound-Guided Posterior Rami Blockade of the Lumbar and Sacral Nerves

Visibility of the needle shaft and tip is critical for ultrasound‑guided peripheral nerve blocks. Currently, most puncture needles used in ultrasound‑guided nerve blocks only allow visualization of the moving needle trajectory as it displaces surrounding tissues. When the target site is deep or the insertion angle is steep, the entire needle—particularly its tip—is poorly depicted on ultrasound images, posing potential safety concerns. A novel puncture needle features numerous grooves at the distal end of the shaft, which enhance ultrasonic reflection toward the transducer, thereby improving needle visualization on ultrasound. This provides clinicians with an additional option for ultrasound‑guided nerve blockade, as the increased echogenicity of the needle facilitates more precise imaging, enhances puncture accuracy, and reduces procedural risks. In summary, ultrasound can accurately identify the lumbar transverse processes and facet joints, enabling guidance for lumbar medial branch nerve blocks. Compared with conventional puncture needles, echo‑enhanced needles yield higher success rates and greater overall pain relief in ultrasound‑guided lumbar medial branch nerve blocks. By improving image clarity and procedural accuracy, these enhanced needles contribute to improved clinical safety and hold promising prospects for widespread use in practice.

Chinese Expert Consensus on Intrathecal Labor Analgesia (2021 Edition)

General anesthesia? Regional anesthesia? Nerve block!

Anesthesia—many people assume that there are only two types: general anesthesia and regional anesthesia. One involves a single injection and a quick inhalation, allowing the patient to sleep through the procedure; the other is an “abacus‑style” injection that numbs the lower half of the body. Of course, there’s also a “mature yet youthful” form of anesthesia: nerve block anesthesia.
