[Normovolemic hemodilution in the treatment of XXXX ].

@entity1 @entity393 @entity2459
After the apparition of a @entity2459 , 45 @entity1 (22 @entity1 and 23 @entity1 , with a mean age of 44 +/- 14.9 years) were treated with normovolaemic haemodilution performed with dextran 60. They were placed into 4 groups depending on their @entity393 : total loss: 10 cases; severe loss: 90 to 70 db. 13 cases; moderates loss: 65 to 40 db, 14 cases, slight loss: less than or equal to 35 db, 8 cases. The mean time between the onset of the @entity393 and treatment was 9.3 +/- 12.4 days. The initial mean haematocrit was 44.8 +/- 3.8% and mean haematocrit after haemodilution was 33.1 +/- 2.8%. For 51% of the @entity1 , an almost total recovery was obtained. In 15.5% of cases, recovery was between 25 to 50% of the @entity393 , and in 33.3% of the @entity1 recovery was negligible. We did not find any relationship between hearing recovery and initial haematocrit. The best results were obtained in the group of @entity1 treated early. Hearing gain was significatively better if delay in starting treatment was less than 7 days. There was a relationship between the initial @entity393 and the final recuperation. These results suggested that haemodilution increased labyrinth microcirculation and oxygenation of the cochlear sensory cells, reversing the ischaemic insult to these cells.
