通过对48例阻塞性睡眠呼吸暂停综合征(Obstructive Sleep Apnea Syndrome,OSAS)行腭咽成形手术前后血液流变学的对照研究,认为合并高原红细胞增多症OSAS在全血粘度低切、全血粘度中切、血浆粘度、红细胞压积、红细胞计数方面较不合并高原红细胞增多症有明显升高,手术后与手术前相比前述指标除血浆粘度外均有明显下降。行腭咽成型术是当前治疗阻塞性睡眠呼吸暂停综合征行之有效的办法。 48 cases of obstructive sleep apnea syndrome (Obstructive Sleep Apnea Syndrome, OSAS) velopharyngeal surgery before and after the hemorheology control study, that combined high altitude polycythemia OSAS in the whole blood viscosity low cut, whole blood viscosity In addition, there was a significant increase in central cut, plasma viscosity, hematocrit, and erythrocyte count compared with non-merger plateau polycythemia. The above indexes were significantly lower than those before surgery except plasma viscosity. Line velopharyngeal angioplasty is currently an effective treatment of obstructive sleep apnea syndrome.
