患有心血管疾患、高血压、冠心病的老年人常发生后鼻出血。出血是来源于颌内动脉的鼻支,而非来自筛动脉。后鼻填塞止血可致感染,并有损伤粘膜、血气异常和死亡的危险。Padrnos曾用经腭大孔翼腭窝赛洛卡因-麻黄素注射疗法获得成功。Weingarten用同法注射赛罗卡因和甘油,效果亦佳。本文作者将上法加以改进,根据30个颅骨(60侧)和4个尸头(8侧)测量硬腭在蝶腭孔、圆孔、眶下裂、视神经孔等处的距离皆在2.5cm以上,又根据腭大孔的方向与硬腭水平面呈向后上方60～80°角,用长为4cm的20～25号针头,在距针尖2.5cm处弯成60°角,以便在腭大孔处进针,不致刺入太深而误入颅内或眶内。因为翼腭窝是一脂肪封闭的间隙,注入液体需用一定的压力,一般用不含肾上腺素的1％赛洛卡因2～3ml,于一分半钟内注射完毕,若注入5 ml则患者会
Epilepsy often occurs in the elderly with cardiovascular disease, high blood pressure and coronary heart disease. Bleeding is derived from the nasal branch of the internal carotid artery rather than from the screen artery. After nasal packing bleeding can cause infection, and damage the mucous membranes, abnormal blood gas and the risk of death. Padrnos has been successful with the injection of the cocatropine-epinephrine injection through the palatal foramen ovale. Weingarten with the same method of injection of cirarubone and glycerol, the effect is also good. The author of the method to be improved, according to 30 skull (60 side) and 4 cadaveric head (8 side) measuring the hard palate in the sphenopalatine foramen, orbital fissure, optic nerve hole distance at 2.5cm or more , And according to the direction of the large palate and hard palate level above the back 60 ~ 80 ° angle, with a length of 4cm 20-25 needle, at a distance of 2.5cm from the tip into a 60 ° angle so that in the palatal hole Needle, not piercing too deep and into the intracranial or intraorbital. Because the pterygopalatine fossa is a fat-filled gap, a certain amount of pressure is required to inject the liquid. Generally, 2 to 3 ml of 1% of the caprine containing epinephrine is injected in one and a half minutes. If 5 ml is injected Patient will
