摘　　要：目的寻找诊断轻度腕管综合征(CTS)敏感的神经电生理指标。方法回顾性分析经吉林大学第一医院手外科医生临床诊断,并经手术治疗疗效确实,但常规电生理检查提示拇短展肌复合肌肉动作电位的潜伏期(CAMP)及示、中指感觉神经传导检查正常的患者80人,共92例手的腕管综合征患者进行神经电生理分析,采用顺向法记录掌腕正中、尺神经混合神经电位潜伏期时差和环指腕正中、尺神经感觉神经电位潜伏期时差,以潜伏期时差差值≥0.4ms为阳性指标,计算其阳性符合率,并进行统计学分析。结果掌腕正中、尺神经混合神经电位潜伏期时差≥0.4ms为64例,阳性率为69.56%;环指腕正中、尺神经感觉神经电位潜伏期时差≥0.4ms为83例,阳性率为90.21%。其中两种方法均为阳性的62例,均为阴性的7例。结论环指腕正中、尺神经感觉神经电位潜伏期时差在诊断轻度腕管综合征时具有较高的诊断价值。Objective To find a sensitive electrodiagnostic indicators for patients who with mild carpal tunnel syn- drome（CTS）. Methods Retrospective Analysis 80 patient,including 92 hands,with carpal tunnel syndrom patiens who was clinical diagnosed by the hand surgeon of the First Hospital of Jilin University and was exactly treated by surgical, but those patients prompted that the potential period of the abductor pollicis brevis compound action muscle （CAMP） and indexmiddle finger feels nerve conduction were normal by theconventional electrodiagnostic examination, and now,a total of 80 patients with carpal tunnel syndrome by neurophysiological analysis,using forward method records both the differences between median and ulnar palmar latencies and the difference between median and ulnar latencies from D4 stimulation, and the positive indicators of the potential latency is ≥ 0.4ms, then calculate the positive coincidence rate, and use statistics analyzing these indicators. Results There are 64 hands which the differences between median and ul- nar palmar latencies is ≥ 0.4ms; the positive rate was 69.56%. There are 83 hands which the difference between median and ulnar latencies from D4 stimulation is ≥ 0.4ms; the positive rate of 90.21%. There are 62 hands which poten- tial latency is ≥ 0.4ms in both of methods,Only 7 cases which in both of methods have no positive findings. Conclusion Q The difference between median and ulnar latencies from D4 stimulation have a high diagnoslic value for detecting the mild and atypical carpal tunnel syndrome.
