眼睑下垂是重症肌无力(myasthenia gravis,MG)常见的症状,且腾喜龙试验常常阳性,特别是眼肌型。肌无力症状常有受热加重、受冷减轻现象。作者利用这种效应对10例 MG 和7例对照组病人作了冰袋试验。将冰袋(把冰放入毛巾内或手套内)置于一侧轻轻闭着的眼表面约2分钟,或以病人能耐受为度。如果双侧眼睑下垂,则放于严重的一侧,在放置冰袋后用温度探针测眼睑皮温,待病人的温度低于29℃以后,则拿走冰袋,应避免眼睑皮温降得过低(18°～22℃)而诱发强直性肌力减低。5分钟后,静注腾喜龙10mg。
Eyelid ptosis is a common symptom of myasthenia gravis (MG), and the Tenzinon test is often positive, especially ocular. Myasthenia gravis symptoms are often aggravated by cold to reduce the phenomenon. The authors used this effect on 10 patients with MG and 7 patients in the control group made an ice pack test. Place the ice pack (place the ice in a towel or glove) on the side of the gently closed eye for about 2 minutes, or for the patient’s tolerance. If the bilateral ptosis, then placed on the serious side, after placing the ice bag with a temperature probe to measure eyelid skin temperature, until the patient’s temperature is below 29 ℃, then remove the ice bag, should avoid eyelid skin temperature drop too Low (18 ° ~ 22 ° C) and induce ankylosing muscle weakness. After 5 minutes, intravenous Tengxilong 10mg.
