Background & Objective: Unnecessary pre-operative ordering of red blood cells (RBCs) in elective surgeries increases costs and waste of blood inventory. Maximum surgical blood order schedule (MSBOS) is a helpful strategy in the estimation of blood units needed for surgery and the prevention of overconsumption. In this study, an MSBOS for pediatric cardiac surgeries is designed.Methods: In this cross-sectional study, we included all pediatric patients who underwent elective cardiac surgery in Children’s Medical Center in Tehran, Iran, from March 21, 2019, to September 22, 2019. Data consisted of the type of surgery and the number of blood units transfused and units cross-matched, based on which cross-match to transfusion ratio (CTR), the transfusion index (TI), and transfusion probability (T%) were calculated.Results: Overall 205 pediatric patients were included in the study. Four hundred and ten RBCs units were cross-matched, and 262 were transfused. The overall results of the CTR, T%, and TI for all the eight types of cardiac surgery were 1.56 (410/262), 76% (157/205), and 1.28 (262/205), respectively. The raw MSBOS for cardiac surgeries included ventricular septal defect, tetralogy of fallot, dextro-transposition of the great arteries, atrial septal defect, aortic coarctation, patent ductus arteriosus, pulmonary stenosis, and pacemaker insertion, which were 1.58, 1.03, 1.54, 1.66, 0.77, 0, 1.25, and 0 unit, respectively, and the figures were rounded up.Conclusion: Accurate MSBOS protocols reduce cross-match workload in laboratories, lead to the appropriate use of blood stocks with less wastage, save human and economic resources, and eventually, promote patient safety.

One of the most important ways to prevent blood transfusion reactions is to choose a suitable donor. Donated blood bags are checked at the time of administration for infectious agents and the compatibility of blood groups between the donor and the recipient. However, gender mismatch is ignored, which can cause complications following injection.

Background and Objective: Patients with thalassemia major have an abnormality in hemoglobin synthesis and ineffective hematopoiesis and for this reason with respect to disease severity should receive one or more fresh blood unit every 15-30 days. Since transfusion of blood products has been known as one of the routes of HIV infection, therefore, this study was conducted to evaluate the prevalence of HIV infection in thalassemic patients under transfusion in Hajar hospital in 2006. Materials and Methods: Descriptive strategy of this study was conducted on 73 serum samples from patients with thalassemia major as referrals of Hajar hospital. In this respect, HIV-Ab of the samples was assessed using ELISA method. For each patient, information including age, gender, and date of 1st blood transfusion were collected. The presence or absence of HIV1 and/or HIV2 antibodies was determined with regard to absorption cut-off value. HIV-Positive samples with absorption greater than 0.8 were further studied using PCR. Results: Out of 73 studied patients, 36 and 37 cases were male and female respectively. The mean age of patients was 10.3 ± 4.9 years. All of the patients had blood transfusion from 1991.The prevalence of HIV-positive in these patients was 0%. Conclusion: This result can be attributed to probably low incidence of HIV in blood donors and precise screening of blood products by Blood Transfusion Organization.
