[Anesthesia for modified radical mastectomy with breast reconstruction].

We investigated the factors influencing the amount of intraoperative bleeding, the factors influencing postoperative blood transfusion and the effect of postoperative analgesia retrospectively in 71 patients who underwent modified radical mastectomy with breast reconstruction. The amount of intraoperative bleeding decreased significantly in hypotensive anesthesia using epidural anesthesia compared with that with prostaglandin E1. Patient's weight and body surface area are the factors which influenced the amount of intraoperative bleeding. No patient received intraoperative blood transfusion. The amount of postoperative bleeding was significantly greater in 14 cases with blood transfusion and the amount of intraoperative bleeding was not significantly greater in blood transfusion cases. Fifty-one patients received epidural morphine intraoperatively. The dosage of postoperative analgesic was significantly less in these patients.
