摘要

Background

Liposuction is a standard treatment for advanced-stage lipedema, often involving large volumes of tumescent fluid infiltration and aspiration. These shifts raise concerns about postoperative electrolyte imbalances, though systematic data are limited.

Methods

This retrospective single-center study analyzed 116 women with stage 2 or 3 lipedema who underwent liposuction between 2019 and 2023. Pre- and postoperative (within 24 hours) laboratory values including hemoglobin, hematocrit, leukocytes, and electrolytes were compared using paired t-tests, and correlations with clinical variables were assessed.

Results

Postoperatively, lower hemoglobin (13.6 ± 0.9 to 11.8 ± 1.2 g/dL, p < .0001) and hematocrit (40.9 ± 2.5 to 35.1 ± 3.5%, p < .0001) levels were observed, alongside higher leukocyte counts (7.6 ± 3.1 to 13.1 ± 5.9 × 109/L, p < .0001). Electrolyte shifts included higher chloride (104.7 ± 2.2 to 106.0 ± 1.9 mmol/L, p < .0001) and slightly lower calcium (2.3 ± 0.1 to 2.2 ± 0.1 mmol/L, p < .0001), sodium (140.8 ± 2.1 to 140.2 ± 2.1 mmol/L, p = .01), and potassium (4.1 ± 0.35 to 4.0 ± 0.4 mmol/L, p = .02). All parameters remained within physiological ranges and were not associated with adverse outcomes. Calcium correlated with hemoglobin (r = 0.49) and hematocrit (r = 0.51) and inversely with aspirate volume (r = −0.41, p = 0.001).

Conclusions

Post-liposuction electrolyte and hematologic changes are mild and clinically insignificant, reflecting predictable hemodilution rather than metabolic disturbance. Routine postoperative testing appears unnecessary for most patients, supporting selective monitoring in those with abnormal baseline values, high aspirate volumes, or relevant comorbidities.
