Thirty-day typing and screening for patients undergoing elective surgery: experience at a large cancer center

Transfusion

Abstract

Preoperative testing in patients scheduled to undergo surgery often includes determining the ABO group and Rh type and screening for atypical alloantibodies in blood samples. AABB recommends obtaining blood samples within 3 days of transfusion. This was extended to 30 days to minimize the number of phlebotomies, avoid delays in providing blood during surgery, and decrease the laboratory workload. This study was conducted to show that extending the expiration date of the preoperative blood sample for blood typing and screening to 30 days will serve our purpose and provide better patient care. Data were collected for all patients undergoing elective surgery with perioperative blood samples submitted to our blood bank over 31 months. Each patient completed a questionnaire to determine whether his or her samples qualified for a 30-day preoperative clot. The questionnaires were validated upon preoperative screening. A transfusion medicine physician made the final determination regarding whether the samples qualified for 30-day typing and screening. These blood samples were used for cross-matching to find compatible blood during surgery. A total of 12,310 preoperative blood samples were received with a request for typing and screenin...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
