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...

Skeletal Muscle Relaxants: Therapeutic Uses

Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx as...

Peripherally and Centrally Acting Muscle Relaxants: A Comparison

Skeletal muscle relaxants can target the central nervous system [CNS] to reduce muscle tension or act directly at the neuromuscular junction to induce temporary paralysis. These two classes of muscle relaxants are called centrally acting muscle relaxants and peripherally acting muscle relaxants. They differ in their action, mechanism, administration route, and clinical uses.
Centrally acting muscle relaxants can be further divided into spasmolytic and antispasmodic drugs. Spasmolytic drugs,...
Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Area of Science:

  • Neurology
  • Surgical Procedures

Background:

  • Meralgia paresthetica (MP) involves lateral femoral cutaneous nerve (LFCN) entrapment, causing thigh pain and dysesthesia.
  • Treatment consensus for medically refractory MP remains elusive, particularly regarding long-term neurolysis effectiveness.

Purpose of the Study:

  • To retrospectively analyze long-term outcomes of LFCN neurolysis for medically refractory MP.
  • To clarify the effectiveness of neurolysis in providing sustained relief for MP patients.

Main Methods:

  • Retrospective analysis of 11 patients undergoing LFCN neurolysis over 7 years.
  • Preoperative confirmation of nerve entrapment via electrodiagnostics or anesthetic blocks.
  • Surgical decompression at pelvic exit, inguinal ligament, and thigh fascia.

Main Results:

  • 12 decompression procedures were performed in 11 patients.
  • Complete symptom improvement in 81.8% and partial in 18.2% of cases.
  • Average follow-up of 33 months with no reported recurrence.

Conclusions:

  • LFCN neurolysis is a viable option for long-term pain relief in medically refractory MP.
  • Accurate diagnosis, including electrodiagnostics and nerve blocks, is crucial for successful outcomes.
  • Thorough decompression considering anatomical variations is essential for surgical planning.
