Abstract:
OBJECTIVE To study the clinical features of OSAHS patients closely associated with supine position. METHODS The clinical data of 105 patients with OSAHS diagnosed by overnight polysomnography(PSG)were retrospectively studied. The patients were divided in two groups: the positional patients(PP)group, those patients who had a apnea-hypopnea index(AHI) that was at least two times higher than the lateral AHI, and the non-positional patients(NPP)group, those patients in whom the AHI in the supine position was two times less than that in the lateral position, and the two groups were compared with age, BMI and the severity of OSAHS. RESULTS The difference of age and BMI were not significant between the two groups[(40.4?10.5)year versus(37.0?10.6) year,(28.2?3.8)kg/m2 versus(29.1?3.0)kg/m2]. There was significantly different in AHI between two groups[(36.8?25.4)/h versus (51.2?29.0)/h ]. AHIsupine and AHInot-supine was significantly different in mild and moderate OSAHS patients [(23.9?13.8) /h versus(12.4?10.1)/h ]. CONCLUSION Mild and moderate OSAHS patients are mainly PP. Positional therapy should play an important role in treatment of mild and moderate patients.
