Fig. 2From: Protective effect of remifentanil on blood loss in endoscopic subcutaneous mastectomy: a retrospective studyBlood loss in mastectomies. Two types of mastectomies—partial mastectomy (a) and quadrantectomy (b)—were associated with a significant reduction in blood loss (partial mastectomy: 60 ml vs. 90 ml, P < 0.001; quadrantectomy: 90 ml vs. 140 ml, P = 0.001, Mann–Whitney U test).
