Abstract
BACKGROUND: Intraoperative nerve stimulation is done routinely in brachial plexus and peripheral nerve surgery as well as in selective neurectomy in spastic patients. OBJECTIVE: The current study compares the use of 2 different devices for nerve stimulation: a totally disposable nerve stimulator and a nerve stimulator used for nerve blocks by anesthetists. METHODS: A retrospective study of 60 patients who underwent brachial plexus surgery: In 30 patients, we used the totally disposable nerve stimulator (group 1) and in another 30 patients, we used the anesthesia device (group 2). The cost of disposable materials used for nerve stimulation was calculated in each group. The same surgeon performed all operations, and he was asked to give his subjective opinion regarding the convenience and ease of use of the device in each group. RESULTS: The main advantages of the totally disposable device are its placement totally within the sterile field, and it is operated by the surgeon without the need to communicate with the anesthetist. However, the totally disposable device had several major disadvantages when compared to the anesthesia device. Firstly, the disposable stimulator can only deliver 0.5, 1.0, and 2.0 mA stimuli, while the anesthesia device can deliver stimuli of 0.1 to 5 mA (in 0.1 mA increments). Secondly, the disposable stimulator frequently fails to operate during surgery, and this is not experienced with the anesthesia device. Finally, the cost of disposables is less using the anesthesia device. CONCLUSION: Our center has stopped using the disposable nerve stimulator in favour for the anesthesia device.
