[Effects of uvulopalatopharyngoplasty on hemorheology in patients with obstructive sleep apnea hypopnea syndrome].
OBJECTIVE
To observe the effect of UPPP on hemorheology in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).


METHODS
Thirty patients of moderate or severe OSAHS were randomly selected from February 2004 to February 2006 in our hospital. Among them, 11 cases are moderate OSAHS (AHI<40), 19 cases are severe OSAHS (AHI>40). They were received uvulopalatopharyngoplasty. Whole blood specific viscosity, erythrocytic and erythrocyte aggregation index were detected before and after operation.


RESULTS
The values of testing in post operation were significantly lower than that in pre-operation (P<0.01).


CONCLUSIONS
Uvulopalatopharyngoplasty has can improve abnormity of hemorheology of OSAHS and decrease the danger of cerebrovascular disorder.
