A Betrayal of Our Handiwork: Postoperative Hemorrhage and the Need for Reoperation

Abstract

Postoperative hemorrhage (PH) that requires reoperation to control bleeding represents a potentially life-threatening and avoidable complication that could have serious implications for recovery. All surgical patients were reviewed who developed PH and required reoperation for control of hemorrhage over a 12-year period, to examine contributing factors possibly related to surgeon misadventure. Of 89,663 operations during this period, there were 1,031 patients (1.2%) who developed PH. Of these, 36 patients required reoperation for control of PH (0.04%), including, general surgery (17), otolaryngologic (9), cardiovascular (9), and gynecologic (1) patients. In 27 general, cardiovascular, and gynecologic patients (29 reoperations), the age ranged from 6 to 91 years. Almost one-half of patients (56%) developing PH were on preoperative anticoagulation. Estimated operative blood loss (EBL) was moderate (EBL = 100-500 mL, 48%). Most patients were normothermic (80%) and normotensive (93%) intraoperatively. The decision to reoperate was not made for at least 8 hours in 55 per cent of patients. At reoperation 10/29 patients were hypotensive. In 20/36 patients (56%) the reoperation note did not identify a single source of bleeding. PH is a distinctly uncommon complication of surgery and often not due to obvious surgeon misadventure. Reoperation for PH is even rarer and embarked upon with reluctance, frequently not yielding a discernible cause for hemorrhage.
