Quality Assessment of Blood Transfusion in Operating Room / 대한구급학회지

ABSTRACT

BACKGOUND: Transfusion of red blood cells is a life saving measure in the management of a variety of surgical conditions. A guideline for blood transfusion during elective surgical procedure is necessary to reduce the risks of transfusion-associated complications, excessive blood bank workload, excessive blood request and overtransfusion, and the cost. From this, a program of quality assessment was adopted to improve blood transfusion practice and to establish the guideline for blood transfusion in elective surgery at Pusan National University Hospital. METHODS: Fifty-six patients undergoing elective surgery was divided 2 groups. Transfusion (T) group was 18 persons. Non-transfusion (NT) group was 38 persons. The preoperative, pre-transfusion, postoperative, and post-transfusion hemoglobin (Hb), hematocrit, mean arterial blood pressure (MAP), heart rate (HR), average amount of transfused red blood cell units, allowable blood loss, and the amount of infused crystalloids and colloids was estimated for 9 months in Pusan National University Hospital. RESULTS: There were no significant differences in Hb between T & NT group. Hb decreased significantly until postoperative 3rd day in NT group. Platelet count decreased in NT group on postop. 3rd day. There were no significant differences in MAP & HR. One-ninth of T group was overestimated blood loss & 18.4% of NT group was underestimated blood loss. One-third of transfusion patient were overtransfused & 36.2% of transfused RBC was unnecessary. Nearly 90% of patient was transfused packed RBC with FFP concurrently. CONCLUSIONS: To minimize overtransfusion, transfusion based on intraoperative hematocrit is necessary. If possible, single use of packed RBC is recommended when the blood loss is below allowable blood loss. In massive bleeding above allowable blood loss, combined administration of FFP and packed RBC or transfusion of whole blood will be better.
