Do we adequately assess natremia in cardiovascular surgery?

Introduction: The unquestionable progress of cardiac surgery and its technological development has not been able to leave behind the burden of its high morbidity, mortality and high costs, therefore, the search for biomarkers that can predict adverse effects and perioperative complications in time and facilitate a better evaluation of these patients continues. Objective: to evaluate the degree of association of natremia with the appearance of serious perioperative complications Methods: An ambispective cohort study was carried out on patients who underwent major cardiovascular surgery between January 1, 2019 and December 31, 2023 at the Cardiocentro of Santiago de Cuba, who met inclusion criteria. Results: A close link was demonstrated between the occurrence of severe perioperative complications and preoperative sodium concentration (p=0.000 RR 1.83) Conclusions: The occurrence of complications was high but in accordance with what has been found in the international and national literature, the monitoring of preoperative sodium concentration could be included as an additional parameter for monitoring, early detection and treatment of complications and consequently reduce the high morbidity and mortality of these patients.
