Abstract:
Objective To evaluate the change situation of cognitive function in the patients with chronic renal failure (CRF) complicating obstructive sleep apnea syndrome(OSAS) .Methods Sixty‐two inpatients with non‐dialysis CRF in our hospital from September 2013 to January 2015 were selected and divided into the group O (complicating OSAS ,31 cases) and group N(without complicating OSAS ,31 cases) ,and contemporaneous 33 individuals undergoing the physical examination were taken as the control group(group C) .The cognitive function was evaluated by the Montreal cognitive assessment (MoCA) .The apnea hypopnea index (AHI) and lowest pulse oxygen saturation(LSpO2 ) at night were measured with a portable sleep monitor .The comparative analysis was performed .Results In the group O ,there was 14 cases of patients(45 .16% ) whose MoCA total score was less than 26 points , while there was only 3 cases(9 .68% ) in the group N ,the difference was statistically significant (P<0 .05) .The MoCA total score , scores of visuospatial and executive function ,attention ,delayed recall and orientation in the group O and N were lower than those in the group C ,while the MoCA total score ,attention and delayed recall in he group O were lower than those in the group N ,the score of language was lower than that in the group N and C ,the differences were statistically significant (P< 0 .05) .The MoCA total score was negatively correlated with serum creatinine and AHI (r= -0 .374 ,r= -0 .408 ,P<0 .05) ,and positively correlated with the GFR level and night LSpO2 (r=0 .382 ,r=0 .519 ,P<0 .05) .Conclusion The patients with CRF complicating OSAS increase the risk of cognitive impairment .
