摘要 目的分析维吾尔族与汉族阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者日间高碳酸血症的发生率及相关因素。方法2015年1—12月克拉玛依市中心医院呼吸与危重症医学科睡眠中心住院的221例OSAHS患者,其中汉族179例,维吾尔族42例;均经睡眠呼吸监测、夜间血氧饱和度(SaO2)监测、日间血气分析、肺功能及口腔阻断压测定。分析患者日间高碳酸血症的特点,并采用非条件Logistic回归分析日间PaCO2水平及其相关因素。结果221例患者中有16.7%(37/221)伴有日间高碳酸血症。伴高碳酸血症患者的体质指数(BMI)、呼吸暂停指数(AHI)、SaO2低于90%时间占总记录百分比(SIT90%)、口腔阻断压(P0.1)均显著高于不伴高碳酸血症者[(31.6±5.6)比(27.9±1.7)kg/m^2、(40.9±26.3)比(32.2±20.1)次/h、(38.6±31.9)%比(23.9±23.6)%、(3.08±2.86)比(2.03±1.20)mmHg,1mmHg=0.133kPa],而夜间平均SaO2、最低SaO2、PaO2均显著低于不伴高碳酸血症者[(86.0±15.5)%比(92.0±3.0)%、(68.9±13.0)%比(75.3±9.9)%、(74.5±23.0)比(86.1±14.8)mmHg](均P〈0.05)。维吾尔族患者夜间平均SaO2、最低SaO2均显著低于汉族,PaCO2、口腔阻断压均显著高于汉族(均P〈0.05)。结论维吾尔族与汉族OSAHS患者日问高碳酸血症相比具有较高的日间二氧化碳分压,与AHI、BMI、平均SaO2、P0.1有关。 Objective To evaluate the incidence and factors related to daytime hypercapnia in Han and Uygur patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods There were 221 patients with OSAHS (include 179 Han patients and 42 Uygur patients) in Sleep Center of Department of Respiratory and Critical Care Medicine of Karamay Central Hospital from 2015, Jan to Dec. All the patients underwent polysomnography (PSG), nocturnal oximetry, daytime blood gas analysis, pulmonary function test and Mouth occlusion pressure ( P0.1 ) results were recorded. The features of hypercapnia was analyzed for patients with OSAHS, and linear regression analysis was used to evaluate the arterial carbon dioxide partial pressure (PaCO2 ) levels and related factors. Results Daytime hypercapnia occurred in 16. 7% (37/221) of the 221 patients with OSAHS. Compare with no hypercapnia groups, the body mass [ (31.6 ± 5.6) vs (27.9 ± 1.7) kg/m^2 ], sleep apnea index (AHI) [ (40.9 ± 26. 3 ) vs (32. 2 ±20. 1 ) times/h] , the percentage of time spent at oxygen saturation below 90 ( SIT90 ) [ ( 38.6± 31.9 ) % vs (23.9 ±23.6)% ], P0.1 [ (3.08±2. 86) vs (2. 03 ± 1.20) mmHg, 1 mmHg =0. 133 kPa] were higher in hypercapnia groups, but the mean nocturnal arterial oxygen saturation ( MSaO2 ) [ ( 86. 0 ± 15.5 ) % vs (92. 0 ± 3.0) % ], the nadir arterial oxygen saturation ( LSaO2 ) [ ( 68.9 ±13.0) % vs ( 75.3 ± 9. 9 ) % ] and arterial partial pressure of oxygen (Pa02) [(74.5± 23.0) vs (86.1 ± 14.8) were lower in hypercapnia groups ( all P 〈 0.05 ). Compare with Han patients with OSAHS, MSaO2 and LSaO2 was lower, PaCO2 and P0.1 was higher in Uvgur patients ( all P 〈 0. 05 ). Conclusions Uygur OSAHS oatients with hypercapnia have a higher daytime PaCO2 than the Han counterparts. BMI, AHI, MSaO2, P0. 1 level are all related with daytime hypercapnia in OSAHS.
