La dexmedetomidina intranasal reduce la necesidad posoperatoria de opioides en pacientes sometidos a artroplastia total de rodilla bajo anestesia general

La artroplastia total de rodilla (ATR) causa dolor intenso y los opioides potentes se utilizan habitualmente en la analgesia posoperatoria. La dexmedetomidina es un nuevo fármaco activador de los receptores adrenérgicos alfa-2 indicado para la sedación de procedimientos, pero estudios previos han demostrado efectos analgésicos y antieméticos clínicamente relevantes. Evaluamos retrospectivamente el efecto de la dexmedetomidina intranasal sobre el requerimiento posoperatorio de opioides en pacientes sometidos a ATR.

La dexmedetomidina intranasal administrada intraoperatoriamente reduce el consumo posoperatorio de opioides y puede asociarse con una estancia hospitalaria más corta en pacientes sometidos a ATR bajo anestesia general.

La anestesia general conduce a un aumento de eventos adversos en comparación con la anestesia espinal en pacientes sometidos a artroplastia de rodilla unicompartimental

El volumen de la artroplastia unicompartimental de rodilla (UKA) ha aumentado drásticamente en los últimos años con buenos resultados a largo plazo.

La UKA se puede realizar bajo anestesia general o neuroaxial (es decir, espinal); sin embargo, se sabe poco sobre si existe una diferencia en los resultados según el tipo de anestesia.

El propósito del presente estudio es comparar los resultados perioperatorios entre los tipos de anestesia para pacientes sometidos a UKA electiva primaria.

La anestesia general se asoció con una mayor tasa de eventos adversos y un mayor tiempo de quirófano, así como una menor probabilidad de que se le dé de alta al hogar.

 No hubo diferencias en la duración de la estancia hospitalaria (LOS) o las tasas de reingreso posoperatorio entre los tipos de anestesia.

Anestesia general y desarrollo cerebral en niños / General anesthesia and pediatric brain development

La anestesia general de larga duración influye en la inteligencia de los niños en edad escolar. Long-duration general anesthesia influences the intelligence of school age children. Zhang Q1, Peng Y1, Wang Y2. Author information BMC Anesthesiol. 2017 Dec 19;17(1):170. doi: 10.1186/s12871-017-0462-8. Abstract BACKGROUND: General anesthesia has been linked to impaired brain development in immature animals and young children. In this study the influence of orthopedic surgery under general anesthesia on the intelligence of school age children has been evaluated.  CONCLUSIONS: More than 3 h general anesthesia influenced the IQ of school age children for up to 3 months after orthopedic surgery. Beside extended exposure time to anesthetics additional factors for post-operative IQ reduction were younger children age, mothers with low educational levels and premature birth.

[Epub ahead of print] Abstract The potential for commonly used anesthetics and sedatives to cause neuroapoptosis and other neurodegenerative changes in the developing mammalian brain has become evident in animal studies over the past 15 years. This concern has led to a number of retrospective studies in human infants and young children, and some of these studies observed an association between exposure to general anesthesia as an infant, and later neurobehavioral problems in childhood. This association is particularly evident for prolonged or repeated exposures. Because of the significant growth of fetal interventions requiring sedation and analgesia for the fetus, or because of maternal anesthetic effects, this concern about anesthetic neurotoxicity is relevant for the fetus. The potential for anesthetic neurotoxicity is the most important clinical and research problem in the field of pediatric anesthesiology. This review will first briefly summarize the rapid brain growth and development in the fetus and neonate. Next, animal model data of anesthetic neurotoxicity in the fetus and neonate will be presented, followed by a review of recent human clinical anesthetic neurotoxicity trials. Finally, the rationale for studying dexmedetomidine as a potential neuroprotectant agent in anesthetic neurotoxicity will be reviewed along with study design for two human clinical trials involving dexmedetomidine.

The quality of reversibility of these medications is being questioned, especially when administered to children under 3 years old. The administration of isoflurane elevates intracellular calcium levels which are critical for cell damage resulting in apoptosis. The NMDA and GABA receptors are indirectly involved in the effect of immature brains. The immaturity of the central nervous system associated to the administration of anesthetic agents such as inhaled anesthetics, ketamine, midazolam, nitrous oxide, and others, produces important changes in the brain that have an impact in the child's later life. There are two important elements in the neurotoxicity of anesthetics, dosage and time administration. Repeating anesthetics produces more brain changes. These modifications have resulted in serious behavioral and memory changes in experiments in animals. It is suspected that a similar situation may arise in children who manifest learning disabilities in later stages.  Keywords: Apoptosis; Anesthetics; Children PDF Safe Anaesthesia Worldwide Delivering safe anaesthesia to the world's poorest people Informes / Information World Congress on Regional Anesthesia & Pain Medicine April 19-21, 2018, New York City, USA Informes / Information International Anesthesia Research Society Annuals Meetings USA Informes / Information
