Intraoperative Management of Liquids in Liposuction Based on the Variability of the Inferior Vena Cava.

[BACKGROUND] Liposculpture is one of the most common surgical procedures performed, and its success depends on several variables. The most crucial factor is fluid management, which determines faster recovery, shorter hospitalizations, optimized hemodynamic parameters, and adequate urinary output. There is a common misconception regarding the established protocol in clinical practice, resulting in a tendency for patients to become hypovolemic during the recovery period.

[METHODS] A prospective and longitudinal observational study was conducted. We created a database to register different variables from patients who underwent liposuction between August 2022 and December 2024, including 96 patients aged 19-63 years after determining the established inclusion and exclusion criteria. We executed measurements of the IVC as a marker for the hemodynamic status.

[RESULTS] Echographic diameter of the IVC and its collapsibility and distensibility index are highly sensitive markers to evaluate the response to nonrestrictive fluid management. We found an absence of hypovolemia or hypervolemia, controlled intravascular volume redistribution, and low hemodynamic variability.

[CONCLUSIONS] This study suggested the use of nonrestrictive fluid management and the use of standardized guidelines with ultrasound measurement of the IVC.
