目的：研究观察局部浸润麻醉下应用鼻内镜双极电凝对隐蔽性鼻出血的临床治疗影响。方法：择取2011年12月-2013年6月期间我科接收治疗的30例隐蔽性鼻出血患者，均在利多卡因局部浸润麻醉下，通过鼻内镜寻找出血点并且实施双极电凝进行治疗。结果：在利多卡因局部浸润麻醉下，本组30例患者均找到明确出血点，其中鼻中隔顶部嗅裂部者7例，中鼻道后上部者6例，下鼻道后端者13例，蝶筛隐窝4例。全部患者均治愈，其中1次电凝止血者26例，2次电凝止血者4例。结论：利多卡因局部浸润麻醉下有助于发现隐蔽的鼻出血部位，以便双极电凝的治疗操作，保证患者在无痛苦状态下获得良好的止血效果。“,”Objective: To study and observe the clinical treatment effects of local infiltration anesthesia on the endoscopic treatment of bipolar coagulation of concealed epistaxis. Methods: 30 cases of concealed epistaxis patients in our department from December 2011 to June 2013 were selected, and al the patients were given the bleeding point and the implementation of bipolar coagulation treatment by nasal endoscopy under the lidocaine local infiltration anesthesia. Results: Under the Lidocaine local infiltration anesthesia, al the 30 patients were found clear bleeding points, in which 7 cases of top part of the nasal septum olfactory cleft, 6 cases of upper part of the nasal passages, 13 cases of back-end, 4 cases of recessus sphenoethmoidalis.
