Modulating the infiltrate-to-total aspirate volume ratio to optimize outcomes in liposuction surgery

Objective: 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: The patients who have undergone liposuction were randomly divided into five groups, the proportion of the planned infusion dose and the total amount of aspirated mixture was 0.3–0.5, 0.5–0.8, 0.8–1.1, 1.1–1.4, 1.4–1.7, respectively. The intraoperative conditions of the five groups were recorded and the I/A was calculated, and the five groups A, B, C, D, E were finally determined according to the different proportions. The postoperative and complications of the five groups were compared, and the differences between the groups were statistically analyzed. Results: The operation time and blood volume in liposuction bottle were closely related to I/A ratio; The number of dressing changes, length of hospital stay, and the degree of bruising, swelling, and pain in group B and C were less than those in the other groups during the hospitalization. At the same time, the I/A ratio will also affect the postoperative satisfaction of patients. Conclusion: I/A ratio in the range of 0.8–1.1 can achieve satisfactory surgical effect, and when it is about 0.9, it is the best ratio, which can provide a reference scheme for clinical practice.
