KHUNADORN, FUANGFA (PRAMONGKUTKLAO HOSPITAL, BANGKOK, THAILAND)

 

Prospective study of carpal tunnel syndrome was done at Ramathibodi Hospital, Bangkok, diagnosed by clinical and electrodianostic study in one man and twenty-three women, 36 hands. All patients were operated after diagnosis then divided into control group (16 hands) and experimental group (16 hands). The experimental group was treated by electrical stimulation to the median nerve, then follow up by electrodiagnosis at 3 weeks and 8 weeks respectively. While one was performed on controlled groud. The result showed significant difference between 2 groups in dista latency (motor 0.008 msec/day and sensory 0.015 msec/day). This experiment showed the electrical stimulation increased regeneration of nerve is one possibility.

IATROGENIC PERIPHERAL NERVE INJURIES

Eun-Woo Lee, Hye Sim Chung, Min Kvun Sohn (Chungnam National University Hospital, Taejon, Korea)

 

The purpose of this study was to investigate general clinical characteristics of iatrogenic peripheral nerve injuries and to help clinicians to understand and minimize the occurrence of these avoidable events.

Medical records and electrodiagnostic reports were reviewed retrospectively in 1,085 patients who had been examined from January, 1987 to June 1995 due to traumatic peripheral nerve lesion.

The cause of peripheral nerve injuries was iatrogenic in 84 patients among 1,085 patients (7.74%). Brachial plexus was the most common injured nerve. The most common etiology was operation, which was associated in 49 (58.3%) patients, and the other etiologies were birth trauma, compression, or traction, injection, and radiation therapy. The operations directly associated with iatrogenic nerve injuries were neck mass excision in 8 (16.3%) patients, total hip replacement in 4, brain tumor operation in 4, and other various minor and major operations.

From the results above, clinicians are expected to be reformed with iatrogenic peripheral nerve injuries and to try, to prevent these complications.
