Resumen
La sedación acorta significativamente el tiempo de tránsito del contraste intralinfático durante la linfangiografía intranodal en comparación con la anestesia general. Este hallazgo sugiere que el tipo de anestesia es un factor modificable que influye en la función linfática y la duración del procedimiento.
Área de la Ciencia:
- Imágenes médicas
- Anestesiología
- Fisiología linfática
Sus antecedentes:
- La linfangiografía intranodal es una técnica de imagen clave.
- La duración del procedimiento puede verse influida por factores no relacionados con el procedimiento.
- La identificación de factores modificables es crucial para optimizar la linfangiografía.
Objetivo del estudio:
- Para determinar si el tipo de anestesia (sedación vs. anestesia general) afecta el tiempo de tránsito de contraste en la linfangiografía intranodal.
- Investigar el impacto de la administración de un agonista adrenérgico α1 en el tránsito de contraste linfático.
- Identificar los factores no relacionados con el procedimiento que pueden reducir la duración de la linfangiografía.
Principales métodos:
- Estudio observacional retrospectivo de los procedimientos de linfangiografía intranodal (2015-2022).
- Análisis de 147 linfangiogramas de 141 pacientes en dos hospitales académicos.
- Regresión lineal múltiple utilizada para evaluar las asociaciones, controlando los factores de confusión.
Principales resultados:
- La sedación se asoció con un tiempo de tránsito de contraste transformado en logaritmos un 43% más corto (P=0,029), lo que se traduce en un tránsito mediano más rápido de 13 minutos.
- La administración de vasoconstrictores no mostró una asociación significativa con el tiempo de tránsito del contraste.
- La anestesia general aumentó el tiempo de atención de la anestesiología en una media de 16 minutos.
Conclusiones:
- La sedación, no la administración de vasoconstrictores, está relacionada con la reducción del tiempo de tránsito de contraste y la anestesia.
- El tipo de anestesia parece modular la función linfática, lo que sugiere anestésicos como posibles objetivos farmacológicos.
- Este estudio proporciona evidencia clínica para optimizar la linfangiografía a través de la selección de la anestesia.

01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
557
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.

01:13Local Anesthetics: Pharmacokinetics
850
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
929
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...

01:29Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

772
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...
