Resumen
La crema anestésica tópica, una mezcla eutectica de anestésicos locales (EMLA), reduce efectivamente el dolor durante la circuncisión neonatal. Este estudio muestra que EMLA alivia significativamente las respuestas al dolor en los recién nacidos sometidos al procedimiento.
Área de la Ciencia:
- El cuidado neonatal.
- Manejo del dolor Manejo del dolor.
- Cirugía pediátrica en cirugía pediátrica.
Sus antecedentes:
- La circuncisión neonatal es un procedimiento común asociado con dolor.
- El manejo efectivo del dolor es crucial para el bienestar del bebé durante los procedimientos.
Objetivo del estudio:
- Evaluar la eficacia de la crema eutectica mezcla de anestésicos locales (EMLA) para reducir el dolor durante la circuncisión neonatal.
Principales métodos:
- Se realizó un ensayo aleatorizado y controlado en la guardería de recién nacidos de un hospital universitario.
- Se incluyeron veintisiete neonatos masculinos a término (1-3 días de edad).
- El dolor se evaluó utilizando la frecuencia cardíaca, la saturación de oxígeno, la actividad facial y el llanto.
Principales resultados:
- La circuncisión indujo respuestas significativas al dolor, incluido el aumento de la frecuencia cardíaca, la disminución de la saturación de oxígeno y más actividad facial.
- EMLA redujo significativamente la frecuencia cardíaca, mejoró la saturación de oxígeno y disminuyó la actividad facial y el llanto en comparación con el placebo.
- No se observaron diferencias en los parámetros espectrales de llanto entre los grupos.
Conclusiones:
- El procedimiento de circuncisión provoca respuestas mensurables al dolor en los recién nacidos.
- EMLA demuestra eficacia en la disminución de estas respuestas al dolor.
- El EMLA es un agente potencialmente valioso para controlar el dolor asociado con la circuncisión neonatal.

01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

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...

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
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...
01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
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...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
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.

01:30Local Anesthetics: Chemistry and Structure-Activity Relationship
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
