Abstract: OBJECTIVE To explore the analytical methods of transfusion residues for providing the basis of the disposal of doctor-patient disputes. METHODS The standard detection methods were adopted for the composition analysis. Through comparing with reference substance solution, reference solution, and blank solution, it is determined whether the residual liquid contained cefoperazone sodium, dexamethasone sodium phosphate, and potassium chloride. RESULTS The transfusion residues contained the cefoperazone sodium, dexamethasone sodium phosphate, but potassium chloride was not found in it. CONCLUSION This method can be used in analysis of other transfusion residues, and provides reference for dealing with the similar samples.
