[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).

METHOD: 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.

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

CONCLUSION

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