Objective:To investigate the factors relating to bleeding secondary to endoscopic sinus surgery.Method:193 patients suffered from nasal polyps, chronic sinusitis and underwent endoscopic sinus surgery between May 1995 and February 2001 were analyzed. These patients's state of operation affairs tallies with this study's selecting condition and their clinic data was complete. The factors relating to bleeding secondary to endoscopic sinus surgery were analyzed with multiple stepwise regression analysis with STATA31 statistic computer software.Result:20 selected hemorrhage factors were analyzed with multiple stepwise regressions. With these factors progressively removed ,5 items as follows showed relation to the hemorrhage: X18?X19?X9?X11?X20. An optimal regression equation for predicting hemorrhage has been established. According to this equation, the blood loss of endoscopic sinus surgery could be estimated.Conclusion:The clinical signification of 5 factors were recognized: ①X18: Anatomy mark was broken down in former operation and showed difficulty when identified.②X19: Sinus presented proliferation such as scar forming, blood vessel showed hyperemia, sinus wall showed hyperplasia, Aperture being narrow and small.③X9: Sinusitis showed late stages.④X11: Estimated blood loss was significantly greater under general anesthesia.⑤X20: Operation went on over 2 hours. If aforementioned condition appears, blood loss may exceed 200 ml.

目的 :探讨鼻内窥镜手术出血的相关因素 ,以引起临床重视。方法 :对鼻息肉或中鼻甲息肉样变并发鼻窦炎手术病例出血的可能相关因素 ,采用STATA31统计软件进行逐步回归分析。结果 :逐步回归结果有 5项因素入选。根据标准化偏回归系数值由大至小的顺序 (引起出血的可能性由大至小 ) ,排列为X18、X19、X9、X11、X2 0。结论 :临床上应重视下列因素 :X18前次手术解剖标志破坏辨认困难 ,X19鼻窦炎性增生 (瘢痕形成、血管充血、骨壁增厚、窦口狭小 ) ,X9鼻窦炎分期趋向晚期 ,X11采用全麻 ,X2 0手术时间超过 2h ,则手术中出血可能≥ 2 0 0ml。
