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。
Objective: To explore the relevant factors of bleeding after nasal endoscopic surgery in order to arouse clinical attention. Methods: The possible related factors of nasal polyps or middle turbinate polyps complicated with sinusitis were analyzed by stepwise regression using STATA31 statistical software. Results: Stepwise regression results were selected five factors. According to the standardized partial regression coefficient values descending order (the possibility of causing bleeding from descending order), arranged as X18, X19, X9, X11, X2 0. Conclusions: The following factors should be paid more attention to in clinical practice: X18 was found to be difficult to discern the anatomical landmarks of the previous operation, X19 sinusitis hyperplasia (scarring, vascular congestion, wall thickening, narrow sinus ostium), late stage of X9 sinusitis, X11 General anesthesia, X2 0 surgery time of more than 2h, the bleeding may be surgery ≥ 200ml.
