一、临床资料本组92例,男性67例,女性25例,年龄13～61岁。出血在Little氏区70例(左侧27例,右侧35例,双侧8例)。下鼻甲前端22例(左侧13例,右侧9例)。多数病人有反复鼻衄的病史,少则2～3次,多则数10次。表现为局部粘膜麋烂渗血或搏动性小动脉出血(28例)。出血量10～200ml。二、冷冻方法用手持式液氮冷冻喷射枪,距出血部位3～4mm处,使液氮在未完全雾化时直接喷射在病变部位,范围大于病变边缘2～3mm。冷冻前不需麻醉,对个别精神紧张的患者可用1％地卡因作粘膜表面麻醉,有活动出血者,先用1％地卡因副肾上腺素棉片止血后再行冷冻,效果好。冷冻开始,粘膜温度急剧下降,20秒钟后粘膜结霜变白,再继续冷冻30秒即停止,并在鼻前孔松松塞一棉球,48小时后取出。如一次不能治愈。1 First, the clinical data 92 cases of this group, 67 males and 25 females, aged 13 to 61 years. Bleeding was performed in 70 cases of Little’s (27 on the left, 35 on the right, and 8 on both sides). 22 cases of inferior turbinate front (left 13 cases, right 9 cases). Most patients have a history of repeated epistaxis, ranging from 2 to 3 times, as many as 10 times. The performance of local mucosal moose bleeding or pulsatility bleeding (28 cases). Bleeding volume 10 ~ 200ml. Second, the freezing method With a hand-held liquid nitrogen freezing gun, from the bleeding site 3 ~ 4mm Department, so that when the liquid nitrogen is not completely atomized spray directly in the lesion, the range is greater than the edge of the lesion 2 ~ 3mm. Freezing before anesthesia, the individual nervous patients can use 1% of the surface of the mucous membrane for anesthesia, active bleeding, first with 1% dexamethasone adrenaline cotton hemostasis and then frozen again, the effect is good. Frozen began, the mucosal temperature dropped sharply, 20 seconds after the mucous membrane frost white, and then continue to freeze for 30 seconds to stop, and a loose ball in the nose hole loose plug, remove after 48 hours. If once can not be cured. 1
