Abstract:
Objective:To explore a convenient and effective method for calculating intraoperative blood loss in liposuction and volume reduction surgery for establishing intraoperative autologous blood transfusion threshold.Methods:Patients’ clinical, laboratory and surgery related information were collected. The influence of different factors such as the total amount of liposuction, bloody fluid, operation time, and patients’ weight change on blood loss during operation were analyzed. The difference of volume between blood loss recorded by doctors and theoretical calculations was compared. The formula of blood loss during operation was conducted, and then the threshold of autologous blood transfusion was established.Results:A total of 1 136 patients with liposuction due to lymphedema were recruited. There were 65 males and 1 071 females, the median age was 56 years in the non-transfusion group and 55 years in the transfusion group. The total amount of liposuction, bloody fluid, operation time, and body weight changes in patients with liposuction surgery were statistically positively correlated with intraoperative blood loss (spearman coefficient were 0.590, 0.584, 0.560, 0.520, respectively, P<0.01). The theoretical blood loss calculated by the Hemoglobin balance formula is (753.0±418.2) ml. According to the calculated value of blood loss, the intraoperative blood loss fitting formula y(ml)=0.082×total liposuction+ 365, is abtained. The threshold for reinfusion of autologous blood is 2 900 ml of liposuction amount. Conclusions:In this study, a convenient calculation method of blood loss in liposuction and volume reduction surgery was constructed, and a threshold for autologous blood transfusion in surgery was set up. Thus, the indication of early blood transfusion was established.
