Patient Safety and Medication Errors

Preoperative autologous blood donation is commonly performed to avoid homologous blood transfusion during cardiac operations in adult patients.1Sandrelli L Pardini A Lorusso R Sala ML Licenziati M Alfieri O Impact of autologous blood predonation on a comprehensive blood conservation program.Ann Thorac Surg. 1995; 59: 730-735Abstract Full Text PDF PubMed Scopus (25) Google Scholar However, autologous blood donation for children is hampered by technical problems including lack of an adequate blood collection system and acute anemia after blood collection. Given the life span of children, it is most important to avoid the complications of homologous transfusion.2Dodd RY The risk of transfusion-mediated infection.N Engl J Med. 1992; 327: 419-420Crossref PubMed Scopus (366) Google Scholar We describe a technique of scheduled autologous blood donation during preoperative cardiac catheterization and examine the efficacy and safety of this method for use in infants and children. Cardiac catheterization was performed about 2 weeks before elective operations in infants and children weighing at least 5 kg. Autologous blood donation was performed in patients with a hematocrit value of 33% or more and a hemoglobin value of 11 gm/dl or more. Sedation was achieved with thiopental sodium and local anesthesia was achieved with lidocanie hydrochloride. Sheaths were inserted into the femoral artery and vein. After hemodynamic measurements, but before contrast angiography, 10 ml/kg of blood was collected via the arterial sheath. The same volume of lactated Ringer's solution was infused at the same rate through the venous sheath. Collected blood was stored as packed red cells and plasma or as whole blood. Blood erythropoietin concentrations were measured before and after blood collection, and recombinant human erythropoietin (100 U/Kg) was administered intravenously to acyanotic patients on the first and seventh days after blood collection. Cyanotic patients were not treated with recombinant human erythropoietin. Each patient was given ferrous sulfate (2 mg/kg) orally every day. From October 1995 through September 1997, preoperative autologous blood donation was performed in 27 children, including 13 infants (16 boys and 11 girls). Their ages ranged from 6 months to 6 years, 8 months (average 1.9 ± 2.1 years). Their body weights ranged from 5.8 kg to 20.2 kg (average 9.7 ± 5.5 kg). The patients included 21 acyanotic patients (10 with ventricular septal defect, two with congenital coronary artery fistula, and one with ventricular sepral defect plus pulmonic stenosis) and six cyanotic patients (three with tetralogy of Fallot and one patient each with pulmonary atresia plus ventricular septal defect, pulmonary artersia with intact ventricular septum, and single ventricle with pulmonic stenosis). All cyanotic patients received Blalock-Taussig shunts. Surgery was postponed beyond the expiration date of the autologous blood preservation in two patients who had upper respiratory tract infections. The preserved blood was infused into the one patient who was not cyanotic. Of the 27 patients who underwent preoperative autologous blood donation, 25 underwent cardiac operations. The surgical method was anatomic radical operation for all of the patients except one with single ventricle and pulmonic stenosis, who underwent a bidirectional Glenn shunt with the use of cardiopulmonary bypass (CPB). The period between donation and surgery was 5 to 21 days (average 15.4 ± 5.6 days). Autologous blood was used as priming volume for CPB in six patients, to support CPB in seven patients, and for infusion after discontinuation of CPB in 12 patients. No complications related to autologous blood donation, autologous transfusion, or recombinant human erythropoictin administration were observed. Nineteen patients (76%) underwent surgery without homologous blood transfusion. Of the 20 acyanotic patients, 17 (85%) underwent surgery without homologous blood transfusion. However, three of the five cyanotic patients required homologous concentration blood transfusion. The blood erythropoietin concentration before autologous blood donation was 14.2 ± 4.6 mU/ml in the acyanotic patients and 19.8 ± 7.2 mU/ml in the cyanotic patients (p < 0.05). The rate of improvement in anemia from autologous blood collection until surgery was significantly higher in cyanotic patients than that in acyanotic patients (0.19 ± 0.08 gm/dl per day in the acyanotic patients and 0.25 ± 0.13 gm/dl per day in the cyanotic patients, p ≤ 0.05). In our institution, four procedures are used to allow transfusion-free cardiac operations in infants and children: (1) preoperative autologous blood donation, (2) administration of recombinant human erythropoietin,3Tasaki T Ohto H Hashimoto C.

The benefits of this technique include the fact that blood can be collected during complete sedation with minimal patient discomfort and that blood collection in the cardiac catheterization laboratory allows monitoring of hemodynamics. In the present study, the combined use of autologous blood donation at cardiac catheterization and treatment with recombinant human erythropoietin in acyanotic patients refused in a high percentage of transfusion-free operations. Therefore this method may be useful in preventing transfusion-transmitted diseases. In contrast, in cyanotic patients, the transfusion-free surgery rate was low despite high blood erythropoietin concentrations and high recovery rate from anemia after autologous blood-collection until the operation. On the basis of our findings, the strategy for transfusion-free cardiac operations for cyanotic patients should be examined further.
