Effect of Tumescent Lidocaine and Epinephrine Infiltration on Blood Loss in Inferior Pedicle Wise-Pattern Breast Reduction: A Prospective Randomized Study

The idea of infiltrating epinephrine-containing solution in reduction mammoplasty with the aim of reducing blood loss dates back to 1985. Although its use is fairly common among surgeons, scientific evidence supporting such use has been feeble and inconsistent. Therefore, we aimed to investigate the effects of tumescent infiltration of lidocaine- and epinephrine-containing solution on blood loss in reduction mammoplasty. A prospective, randomized, double-blinded study is planned. Forty patients admitted to our clinic for mammary hypertrophy are randomly assigned to experiment and control groups, each of a size of 20 patients. Control group underwent conventional Wise-pattern, inferior pedicle breast reduction, whereas experiment group received tumescent fluid infiltration 20 min prior to making of the incisions. Data including age, body mass index (BMI), comorbidities, operative time, length of hospitalization along with preoperative, postoperative 2nd and 12th hour complete blood counts are recorded for each patient and compared between groups. Data analysis showed no significant difference between groups in terms of age, BMI, comorbidities or preoperative hematocrit levels. Operative time and hospitalization were significantly shorter in experiment group (p < 0.05*). The drop in hematocrit level in both the 2nd (4.93 ± 2.44% to 15.53 ± 7.17%) and 12th hour (9.4 ± 6.79 compared to 21.28 ± 10.15) was lower in the experiment group (p < 0.01*). A multiple variate analysis incorporating preoperative, postoperative 2nd and 12th hour hematocrit levels demonstrated a significant reduction in blood loss with the use of tumescent infiltration (Wilks’ lambda F = 12.84, p < 0.01*). Multiple regression analysis revealed age, BMI, comorbidities, preoperative hematocrit levels and hospitalization did not affect postoperative blood loss (p > 0.05). Duration of operation, however, seemed to affect amount of blood loss postoperatively (p < 0.05*). With outcomes obtained from this study, it is clearly shown that tumescent infiltration significantly reduces blood loss in Wise-pattern, inferior pedicle breast reduction. Furthermore, tumescent infiltration is also shown to decrease operative time and length of hospital stay.
