Resumen
El bloqueo del nervio frénico (PhNB, por sus siglas en inglés) ofrece un beneficio limitado para el hipo intratable. Este estudio encontró un alivio variable y a menudo temporal, lo que resalta la necesidad de una cuidadosa selección de pacientes y tratamientos alternativos.
Área de la Ciencia:
- Neurología; Manejo del dolor intervencionista
Sus antecedentes:
- El hipo intratable, que persiste durante más de 30 días, representa un desafío terapéutico.; El bloqueo del nervio frénico (PhNB) es un tratamiento emergente, pero su eficacia no está bien establecida en diversos grupos de pacientes.
Objetivo del estudio:
- Evaluar el beneficio terapéutico del PhNB en una serie de pacientes con hipo intratable.; Analizar los resultados e identificar los factores que influyen en la respuesta al tratamiento.
Principales métodos:
- Siete pacientes con hipo intratable (idiopático y posprocedimiento) se sometieron a PhNB guiado por ecografía.; Los tratamientos incluyeron anestésico local y dexametasona perineural, con algunos procedimientos bilaterales.
Principales resultados:
- El PhNB demostró un beneficio terapéutico limitado o nulo sostenido en la mayoría de los casos.; El alivio fue temporal en algunos pacientes; uno experimentó una exacerbación de los síntomas.; Se observaron respuestas variables en diferentes etiologías y duraciones del hipo.
Conclusiones:
- El bloqueo del nervio frénico muestra una eficacia variable para el hipo intratable, lo que requiere una cuidadosa selección de pacientes.; Los protocolos estandarizados y la exploración de terapias alternativas son cruciales para el manejo de esta afección.

01:19Depolarizing Blockers: Pharmocokinetics
545
Depolarizing blockers are administered through intravenous injection. Succinylcholine is the most common choice of depolarizing blockers in emergency clinical practices. Although they have a rapid onset, they readily diffuse away from the motor end plate into the extracellular fluid. They are metabolized by enzymes such as liver butyrylcholinesterase and plasma pseudocholinesterases. This produces a short duration of action, typically 5-10 minutes long, unlike nondepolarizing blockers, which...

01:27Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions
842
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.

01:31Skeletal Muscle Relaxants: Therapeutic Uses
847
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...

01:28Depolarizing Blockers: Mechanism of Action
2.6K
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
1.1K
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.
