ABSTRACT

Objective To analysis the correlation of obstructive sleep apnea-hypopnea syndrome (OSAHS) and perihematoma edema of hypertensive cerebral hemorrhage.Methods One hundred and forty-four patients with hypertensive cerebral hemorrhage were collected and 78 of these patients were suffered from OSAHS.The patients were divided into two groups,control and OSAHS group,according to whether were accompanied by OSAHS or not.Both of the groups received the routine treatments including dehydration,reducing blood press,protecting the cerebral cells and so on.Cerebral CT scan was taken on admission.Night polymonography (PSG) was done within 24 hours of admission.Twenty-four hours and 4 days after admission,cerebral CT scan was taken again.The volumes of cephalophyma and perihematoma edema were calculated according to the results of CT scan.The changes of cephalophyma and perihematoma edema were dynamic observed.Results No difference in patients' age,sex,body mass index,serum glucose,blood lipid and so on,was observed between the two groups.The relative edema index became significantly different until 4 days after admission (0.40 ± 0.45,0.96 ± 1.35 in control and OSAHS group respectively,t =4.149,P =0.000).Similarly,the alternation edema index of OSAHS was obviously higher than that of control group only in 4 days after admission.While the analysis of the correlation between different degree OSAHS groups and edema indexes showed that at 24 hours after admission the edema volumes for different degree OSAHS groups were consistent (1.05 ± 0.65,0.84 ± 0.48,1.20 ± 0.54,1.10 ±0.40 in control,slight,moderate and severe groups respectively,F =1.061,P =0.374).At 24 hours and 4 days after admission,the edema volumes were positively correlated with the degree of OSAHS.Alternation edema index was significantly correlated with apnea hypopnea index according to the result of Pearson' s correlation analysis (r =0.652,P =0.000).Conclusion OSAHS complication can promote the progression of perihematoma edema of hypertensive cerebral hemorrhage,and the degree of edema aggravation is positive correlated to the degree of OSAHS.
