Research paper thumbnail of Monitorización sonográfica de la vena cava inferior para la valoración de fenómenos embólicos durante la artroplastia de cadera

Revista española de anestesiología y reanimación/Revista española de anestesiología y reanimación, Feb 1, 2024

Conclusiones: Nuestro estudio sugiere que la monitorización sonográfica de la vena cava inferior ... more Conclusiones: Nuestro estudio sugiere que la monitorización sonográfica de la vena cava inferior a través de una ventana subcostal es factible para la evaluación de fenómenos embólicos durante reemplazos articulares de cadera en el 90% de los casos. La escala de valoración cualitativa de severidad de embolia es altamente reproducible, con una alta fiabilidad intra-e interobservador.

In Uruguay, after cardiovascular diseases, cancer ranks second as a cause of death. According to ... more In Uruguay, after cardiovascular diseases, cancer ranks second as a cause of death. According to official data from the Ministry of Public Health in 2017, 24.6% of deaths were due to this disease. In our specialty, there is great concern about the evolutionary consequences of neoplastic disease related to the surgical anesthetic act, conceptualized from the length of the perioperative period. We consider necessary the inclusion of protocols for neoplastic surgery that favor recovery and evolution in the short and long term. This implies establishing anesthesiological strategies aimed at preserving immunity, by reducing psychological and surgical stress, adequate pharmacological selection, management of the internal environment and analgesia. For these reasons, it is important to establish the implementation of perioperative plans that reduce psychosomatic aggression, which in addition to medical stability, provide quality analgesia, with postoperative well-being that allow rest and recovery. Great advances have been made in tumor resection surgical techniques such as neoadjuvant and adjuvant polychemotherapy techniques, however, tumor recurrence rates have not been reduced as would be desired. Beyond the natural malignancy of the underlying pathology, it is inferred that surgical stress with a long and torpid perioperative period favors tumor recurrence. Hence our special interest in these communications related to patients in the search for solutions that improve their vital prognosis. Based on current evidence, it can be affirmed that the decrease in opiate consumption, especially the decrease in the need for Morphine, may favor better prognoses; maintaining the antimetastatic immune response in a period of special protumoral susceptibility such as the perioperative period. We therefore propose the use of analgesic / anesthetic techniques supported on the basis of regional anesthetic blocks prior to surgical aggression, complemented with the administration of Propofol, NSAIDs and β-blockers during the intraoperative period, through the presentation of 2 clinical cases of patients with osteosarcoma of knee.
