Abstract
La anestesia general inhalatoria en caballos produce depresión del sistema cardiorrespiratorio que junto con el manejo perianestésico característico de esta especie (inducción y recuperación) puede causar complicaciones como parada cardiorrespiratoria, fracturas o miopatías que terminen con la muerte o sacrificio del paciente (Bidwell et al., 2007; Johnston et al., 2002; Johnston, 2005;Senior, 2013). La mortalidad anestésica en équidos es muy superior a la descrita en humana o en pequeños animales, situándose en 0,6% en anestesia no relacionadas con cólico (Brodbelt, 2009;Gozalo-Marcilla et al., 2021).La realización de procedimientos diagnósticos y quirúrgicos en estación mediante sedación profunda permite reducir el riesgo asociado a la anestesia general (Gozalo-Marcilla et al., 2021;Toppen et al., 2017). Estos procedimientos pueden realizarse mediante la administración de fármacos sedantes y analgésicos que se combinan con técnicas de anestesia y analgesia locorregional (Michou & Leece, 2012a, 2012b). Estas combinaciones deben proveer una sedación e inmovilización del paciente adecuados y una potente analgesia perioperatoria con un grado mínimo de ataxia y de depresión cardiorrespiratoria...
General anesthesia in horses produces depression of the cardiorespiratory system that together with the perianesthetic management characteristic of this species (induction and recovery) can cause complications such as cardiorespiratory arrest, fractures or myopathies that can lead to death or sacrifice of the patient (Bidwell et al., 2007; Johnston et al., 2002; Johnston, 2005;Senior, 2013). The anesthetic mortality in equidae is much higher than that described in humans or small animals, with a currently incidence of 0.6% in anesthetic procedures not related to colic (Brodbelt, 2009; Gozalo-Marcilla et al., 2021). Standing diagnostic and surgical procedures under deep sedation reduces the associated risk with anesthesia (Gozalo-Marcilla et al., 2021; Toppen et al., 2017). These procedures can be performed administering sedative and analgesic drugs that are combined with locoregional anesthesia and analgesia techniques (Michou & Leece, 2012a, 2012b). These combinations should provide adequate sedation and immobilization of the patient, potent perioperative analgesia with a minimum degree of ataxia and cardiorespiratory depression...
