Introducción: las infecciones profundas del cuello son patologías complejas con gran potencial de complicaciones graves, que, debido a su ubicación pueden ser de difícil reconocimiento y manejo. Es de gran importancia realizar un diagnóstico asertivo y ofrecer el tratamiento adecuado para poder disminuir las complicaciones que se pudieran presentar. La ecografía es una ayuda diagnóstica cada vez más utilizada que nos puede ayudar a guiar nuestras conductas de manera rápida y efectiva. Caso clínico: presentamos un caso de un paciente con un absceso en cuello, en el que la utilización de la ecografía de manera intraoperatoria facilitó la toma de decisiones y evitó procedimientos invasivos innecesarios. Conclusiones: el Point of Care Ultrasound (PoCUS) es una forma rápida y práctica de resolver preguntas y facilitar la toma de decisiones objetivas en el entorno perioperatorio.
Objectives: To Synthesize the most used adjuvants in spinal anesthesia, summarize the mechanisms of action, indication, dose, adverse events, and safety outcomes described. Methodology: Non-systematic review in the medline, embase, central and Scielo databases without time or language limits, focused on adjuvants in spinal anesthesia, systematic reviews and meta-analyses were selected in order of priority in case they did not have them. Controlled clinical trials were chosen and finally observational studies. Results: 36 original and secondary studies met the inclusion criteria; a narrative review was carried out with the main findings of the same according to the authors. Conclusions: Adjuvants for spinal anesthesia are drugs that are intended to take advantage of a synergistic effect with local anesthetics that can improve the latency of action onset, duration of neuraxial blockade and reduce adverse effects, they stand out for their effects and better safety profile opioid adjuvants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
