Insights

A long hydrophilic sheath significantly reduces radial artery spasm during transradial procedures compared to a short sheath. This innovation improves patient comfort and procedural success in cardiac catheterization.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Access

Background:

  • Transradial approach offers lower access site complications but is underutilized.
  • Radial artery spasm is a significant challenge in transradial procedures.
  • A long hydrophilic-coated sheath may mitigate radial spasm compared to standard sheaths.

Purpose of the Study:

  • To evaluate the efficacy of a long hydrophilic-coated sheath in preventing radial artery spasm during transradial approach.
  • To compare the incidence of radial spasm between long hydrophilic-coated and short sheaths.

Main Methods:

  • A randomized controlled trial involving 351 patients undergoing transradial coronary angiography ± PCI.
  • Patients were assigned to either a long hydrophilic-coated sheath or a short sheath (control).
  • Radial spasm was the primary endpoint, defined by patient pain scores or catheter friction; procedure failure, occlusion, and local complications were secondary endpoints.

Main Results:

  • Radial spasm occurred significantly less frequently with the long hydrophilic-coated sheath (4%) versus the short sheath (18%) (P < 0.001).
  • No significant differences were observed in procedure failure rates (1.2% vs. 0.6%), local complications (0.6% vs. 1.2%), or radial occlusion (3.5% vs. 3.5%).

Conclusions:

  • The long hydrophilic-coated sheath is effective in preventing radial artery spasm during transradial procedures.
  • This sheath offers a promising solution to improve the adoption and success of the transradial approach.

Vascular Spasm01:16

Vascular Spasm

The vascular phase, also known as vasospasm, is the initial stage of hemostasis, crucial for preventing excessive bleeding when a blood vessel is injured. After a vessel is cut, nerves in the damaged area trigger pain and other sensory impulses. Simultaneously, the smooth muscles in the vessel wall contract, resulting in a vascular spasm. This contraction reduces the vessel's diameter at the injury site, slowing or stopping blood loss through the vessel wall. Vascular spasms typically last for...
Spasmolytic Agents: Chemical Classification01:29

Spasmolytic Agents: Chemical Classification

Spasmolytic agents are drugs used to alleviate muscle spasms and spasticity. They can be categorized into different chemical groups based on their mechanisms of action. Centrally acting spasmolytics primarily affect the spinal cord, while others directly target skeletal muscle cells.
A major class of centrally acting spasmolytics is the α2-agonist, such as tizanidine. These drugs bind to α2-adrenoceptors, inhibiting the release of the excitatory neurotransmitter glutamate. They also promote...
Classification of Skeletal Muscle Relaxants01:28

Classification of Skeletal Muscle Relaxants

Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Centrally Acting Muscle Relaxants: Therapeutic Uses

Centrally acting muscle relaxants reduce muscle tone and tension by interfering with the postsynaptic reflexes in the central nervous system.
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...
