Comparison of perioperative stress in patients undergoing thyroid surgery with and without neuromonitoring-a pilot study.
OBJECTIVE
A comprehensive psychological comparison of preoperative stress in patients scheduled for thyroidectomy with versus without intraoperative neurophysiologic monitoring (IONM) has never been reported. The aim of this study was to assess whether a planned utilization of IONM had any effect on the reduction of stress and anxiety level before and after thyroid surgery.


METHODS
The outcomes of 32 patients scheduled for thyroidectomy with IONM were compared to the outcomes of a carefully matched control group of 39 patients operated on without IONM. All the patients were tested before the surgery and at 1-7 days postoperatively employing psychological self-report instruments: the Depression Anxiety Stress Scales (DASS), State-Trait Anxiety Inventory (STAI), 12-item General Health Questionnaire (GHQ), Functional Assessment of Cancer Therapy-Head and Neck Scale (FACT H&N), and the visual analog scale (VAS).


RESULTS
The examined groups were homogenous and carefully matched in terms of mental health (GHQ), the quality of life (FACT H&N), and the intensity of depression level (DASS). The IONM group showed a significantly lower level of "the state anxiety"(STAI) 1 day before the operation (p < 0.05), greater trust in the doctor (VAS) (p < 0.05), and greater confidence in the treatment method (VAS) as compared to the patients in the control group (p < 0.05), while no significant differences were found when the remaining items were compared.


CONCLUSIONS
The planned use of IONM during thyroidectomy may reduce patient anxiety before surgery. However, further research in this area is necessary to confirm this preliminary finding in a larger population of patients.
