神经肌肉病病人用肌松药后常发生严重并发症,如长时间麻痹、高钾血症、肌强直和恶性高热。一、区域性箭毒试验区域性箭毒试验有助于判断神经肌肉病人对肌松药的反应。Brow和Charlton氏法是用止血带扎住病人的前臂,使与全身循环隔绝,再静注含右旋筒箭毒0.5mg的盐水20ml。4.5分钟后,松开止血带,于1、11和21分钟后用序列9次超强电刺激测试尺神经(即9次成串法,频率3 Hz共3秒),记
Patients with neuromuscular disorders often suffer from serious complications after using muscle relaxants, such as prolonged paralysis, hyperkalemia, myotonia and malignant hyperthermia. First, the regional curare test Regional curare test can help determine the neuromuscular response to muscle relaxants. Brow and Charlton’s method is to use the tourniquet tie the patient’s forearm, so isolated from the systemic circulation, and then intravenous injection of right-bellied poison 0.5mg saline 20ml. After 4.5 minutes, the tourniquet was released, and the ulnar nerve was tested with serial nine super-electric stimuli after 1, 11 and 21 minutes (ie 9 in a series with a frequency of 3 Hz for 3 seconds)
