[Autologous blood collection in pregnancy. Prospective study].
Autologous blood predonation during pregnancy, with the aim of autotransfusion after delivery, has gained increasing consensus over the last few years. However, there are still some controversial aspects. In particular, the cost/benefit ratio of institutionalizing the above mentioned practice would appear altogether unfavourable (too many women would be really in need of transfusion after delivery). The aim of the present study is to assess the results of our experience using autotransfusion in obstetrics. This longitudinal and prospective study was carried out on a sample of 29 pregnant women who donated 1 unit of blood during the last month of their pregnancy. Phlebotomy was preceded by a verification of the permitting conditions (Hb > or = 11 g/dl; Ht > or = 33%). Before, during and after phlebotomy, the patients underwent cardiotocographic monitoring and periodic observation of vital parameters. The hematologic parameters registered during the various test (before predeposit, before delivery, in puerpery) were statistically analysed. The hemochromo values appeared satisfactory in all cases at the time of admittance for labour. As a consequence of a hematic loss higher than usual at the moment of delivery, in many cases the hemoglobin values during puerpery did not enable us to exclude a priori the advisability of a transfusion. From the study we see how the cost/benefit ratio of the predeposit practice in obstetrics is less unfavourable than commonly thought.
