Local Anesthetics: Clinical Application as Spinal Anesthesia01:11

Local Anesthetics: Clinical Application as Spinal Anesthesia

744
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...

Muscles of the Vertebral Column01:27

Muscles of the Vertebral Column

1.9K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

517
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
Although all competitive neuromuscular blockers are designed...

Classification of Skeletal Muscle Relaxants01:28

Classification of Skeletal Muscle Relaxants

2.7K
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...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacokinetics

520
All neuromuscular blocking agents are injected intravenously because they are poorly absorbed from the GI tract. Rapid onset is achieved with intravenous administration, although absorption is also adequate from an intramuscular injection. Since these agents are highly ionized, they do not readily penetrate cell membranes or cross the blood-brain barrier.
Instead, they are transported by the blood to different tissues. Muscles with a greater blood supply (arteries) and blood flow receive more...

Skeletal Muscle Relaxants: Therapeutic Uses

608
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...

Summary

Erector spinae plane (ESP) blocks show promise for upper and lower limb regional anesthesia. These blocks offer effective pain relief with preserved motor function, presenting an alternative to traditional anesthesia methods.

Area of Science:

  • Anesthesiology
  • Regional Anesthesia
  • Pain Management

Background:

  • Erector spinae plane (ESP) blocks are an evolving regional anesthesia technique.
  • Their application for limb analgesia is gaining attention in scientific literature.

Purpose of the Study:

  • To review current literature on ESP blocks for upper and lower limb regional anesthesia.
  • To discuss the benefits and drawbacks of ESP blocks in clinical practice.

Main Methods:

  • Literature review of studies investigating ESP blocks for limb anesthesia.
  • Analysis of reported outcomes, including efficacy, safety, and side effect profiles.

Main Results:

  • High thoracic ESP blocks show potential for shoulder pain relief, preserving motor and phrenic nerve function.
  • Lumbar ESP blocks provide effective analgesia for hip procedures, comparable to other blocks but with motor sparing.
  • ESP blocks may block T2 innervation, beneficial for shoulder surgery pain.

Conclusions:

  • ESP blocks offer a viable alternative for upper and lower limb analgesia.
  • These blocks provide adequate pain relief with minimal motor block, useful when other techniques are contraindicated.
