[Computerization of a bank of platelets with HLA phenotype and preserved at -196 degrees C]. / Informatisation d'une banque de plaquettes phénotypées HLA et conservées à -196 degrés C.

ABSTRACT

In order to complete the logistics of the unit cytapheresis, we have developed a decision helping system which rests upon the computer management of -196 degrees C cryopreserved HLA type platelets. The hardware used is a micro-computer equipped with two floppy disks and a printer. Two files have been created namely "Product" and "Patient". Data relating to 800 platelet concentrates may be recorded on a floppy disk. The software which has been developed has several functions 1 - The input of the parameters of a HLA type concentrate with the possibility of reservation for the given recipient; 2 - The print out of the bank's stock; 3 - The selection and the reservation of HLA matched platelets according to the recipient; 4 - The print out of concentrates allocated to each patient, it is possible to thaw out chosen platelet concentrate and a thawing report is printed out, thus enabling one to locate the concentrate in the bank. Thanks to this "aid in decision making", the management of - 196 degrees C cryopreserved HLA type platelets may be carried out. The proposed software allows an one line answer for any emergency transfusion case. Considering the recipient HLA typing the suitable best match platelet concentrates are instantly transfused or save.
