摘 要 目的:分析不同严重程度阻塞性睡眠呼吸暂停低通气综合征(OSAHS)夜间血压波动特点。方法:选取100例OSAHS患者,依据血氧饱和度(SaO2)值与呼吸暂停低通气指数(AHI)分为轻度组(n=40)、中度组(n=36)和重度组(n=24)。比较3组睡眠参数及血压参数,分析不同严重程度OSAHS患者夜间血压波动特点。结果:经Pearson分析,OSAHS患者的AHI、ODI、MAI、TST90与△BP、血压波动频次呈正相关(r>0,P<0.05),LSpO2、MSpO2与△BP、血压波动频次呈负相关(r<0,P<0.05);经线性回归分析显示,中重度OSAHS与夜间血压波动有关(P<0.05)。结论:OSAHS患者夜间血压波动与病情严重程度具有密切相关。

ABSTRACT Objective: To analyze the characteristics of nocturnal blood pressure fluctuation in obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: One hundred patients with OSAHS were selected as the research subject and divided into mild (n=40), moderate (n=36) and severe (n=24) groups, based on blood oxygen saturation (SaO2) and apnea hypopnea index(AHI). The sleep and blood pressure parameters were compared among the three groups and the characteristics of nocturnal blood pressure fluctuation in patients with OSAHS with different severity were analyzed. Results: Pearson analysis showed that AHI, ODI, Mai and tst90 were positively while correlated with △BP and blood pressure fluctuation frequency (r>0, P<0.05), LSaO2 and MSaO2 were negatively correlated with △BP and blood pressure fluctuation frequency (r<0, P<0.05). Linear regression analysis showed that moderate and severe OSAHS were related to nocturnal blood pressure fluctuation (P<0.05). Conclusion: The nocturnal blood pressure fluctuation in OSAHS patients is closely related to the severity of the disease.

阻塞性睡眠呼吸暫停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)临床主要表现为睡眠打鼾、呼吸暂停、白天嗜睡等,且夜间反复出现微觉醒、间歇性低氧及急剧变化的胸内压可导致血压波动,而异常血压波动可增加心脑血管病发生风险,增加患者病死率[1]。有研究表明,OSAHS患者夜间血压波动与心脑血管病发生密切相关[2]。但夜间血压增高程度与呼吸紊乱指数、呼吸紊乱时最低氧饱和度等有关,但不同严重程度的OSAHS患者的呼吸紊乱指数、呼吸紊乱时最低氧饱和度也存在较大差异[3]。故本研究旨在分析不同严重程度OSAHS夜间血压波动情况。
1.1 一般资料
选取我院2019年8月—2020年7月期间收治的100例OSAHS患者作为研究对象,依据血氧饱和度(oxygen saturation,SaO2)值与呼吸暂停低通气指数(apneahypopnea index,AHI)分为轻度组(AHI 5~15次/h,SpO2 85%~89%,n=40),中度组(AHI 16~30次/h,SpO2 80%~84%,n=36),重度组(AHI≥30次/h,SpO2<80%,n=24)。轻度组男25例,女15例;年龄18~70岁,平均(44.08±6.31)岁;……
