Abstract:

Asymptomatic anemia in healthy patients undergoing low risk surgery is rare. In this retrospective study, we examined the records of 9584 ASA class I-II patients scheduled for elective low risk surgery who had a preoperative hemoglobin (hgb) test for the presence of anemia. Hgb <9 g/dL was detected in 75 patients (0.8%). Perioperative management of anemia occurred in no cases of elective surgery in this group. Transfusion of red cells occurred in four other patients, all of whom had hgb >9 g/dL. In all cases, management decisions were based on clinical factors rather than the preoperative hemoglobin test. In healthy patients undergoing low risk elective surgery, routine preoperative hgb testing is not indicated.
