Complication-Free Intra-operative Mismatched Blood Transfusion Under General Anesthesia With an Interdisciplinary Approach: A Case Report.

This report provides a case of a 58-year-old female scheduled for bilateral total knee arthroplasty under general anesthesia who received one unit of packed RBCs intraoperatively. She remained vitally stable throughout the whole procedure. However, by the end of the procedure, it was noticed that the administered blood was incompatible with the patient's blood group. All patient-protective measures were taken including an ICU bed and hematology team consultation. Fortunately, no hemolysis or major complications emerged. The patient was discharged home in good condition by day 6 postoperatively.
