Modulating the Infiltrate-to-Total Aspirate Volume Ratio to Optimize Outcomes in Liposuction Surgery.

BACKGROUND

The purpose of this study was to explore the impact of varying ratio of infiltration fluid doses and the total aspirate mixture (I/A) on the outcomes of liposuction surgery.

METHODS

Patients who have undergone liposuction were randomly divided into 5 groups; the proportion of the planned infusion dose and the total amount of aspirated mixture was 0.3 to 0.5, 0.5 to 0.8, 0. to 1.1, 1.1 to 1.4, and 1.4 to 1.7, respectively. The intraoperative conditions of the 5 groups were recorded, and the I/A was calculated; the A, B, C, D, and E of the 5 groups were finally determined according to the different proportions. The postoperative satisfaction and complications of the 5 groups were compared, and the differences between the groups were analyzed statistically.

RESULTS

The operation time and blood volume in the liposuction bottle were closely related to the I/A ratio. The number of dressing changes; length of hospital stay; and degree of bruising, swelling, and pain in groups B and C were less than in the other groups during the hospitalization. At the same time, the I/A ratio also affected the postoperative satisfaction of patients.

CONCLUSION

An I/A ratio in the range of 0.8 to 1.1 can achieve a satisfactory surgical effect, and when it is approximately 0.9, it is the best ratio, which can provide a reference scheme for clinical practice.
