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.
