During spinal surgery assessing the integrity of the spinal cord can be difficult. To avoid complications tike com-pression, stretching and derangement in circulation it is important to be able to evaluate the neurologic status during surgery. The Wake-Up test is stili performed for this reason.

24 patients undergoing elective spinal ALICI instrumentation were assessed by preoperative physical examina-tion to be neurologically normal. They were premedicated with diazepam 0.2 mg/kg orally. TİVA was performed with 40-60 pg/kg/h alfentanil and 2-3 mg/kg/h propofol. İn ali patients under TİVA, intraoperative Wake-Up test was performed and the neurologic examination was carried out when cooperation to verbal commands occured.

in two patients who shovved changes in amplitude, both showed motor deficit during the Wake-Up test. İn one of two patients who shovved prolongation in latency there was minimal motor deficit postoperatively. The other 20 patients with normal SSEPs remained neurologically normal.

Especially in patients in whom cooperation is poor or neurologic examination is difficult SSEP monitoring has-been found to be valuable.
