Effects of oral diazepam on intravenous access in same day surgery patients

Preoperative anxiety about spinal surgery under general anesthesia

PURPOSE

No study has investigated preoperative anxiety about spinal surgery under general anesthesia. The purposes of this study were (1) to determine how many patients have preoperative anxiety about spinal surgery and general anesthesia, (2) to evaluate the level of anxiety, (3) to identify patient factors potentially associated with the level of anxiety, and (4) to describe the characteristics of the anxiety that patients experience during the perioperative period.

METHODS

This study was performed in 175 consecutive patients undergoing laminectomy for lumbar stenosis or discectomy for herniated nucleus pulposus under general anesthesia. Demographic data, information related to surgery, and characteristics of anxiety were obtained using a questionnaire. The level of anxiety was assessed using a visual analog scale of anxiety (VAS-anxiety). Patient factors potentially associated with the level of anxiety were investigated using multiple stepwise regression analysis.

RESULTS

Of 157 patients finally included in this study, 137 (87%) had preoperative anxiety (VAS-anxiety > 0). The mean VAS-anxiety score for spinal surgery was significantly higher than that for general anesthesia (4.6 ± 3.0 vs. 3.2 ± 2.7; P < 0.001). Sex and age were significant patient factors related to the level of anxiety about spinal surgery (P = 0.009) and general anesthesia (P = 0.018); female patients had a higher level of anxiety about spinal surgery, and elderly patients had a higher level of anxiety about general anesthesia. The most helpful factors in overcoming anxiety before surgery and in reducing anxiety after surgery were faith in the medical staff (48.9 %) and surgeon's explanation of the surgery performed (72.3%), respectively.

CONCLUSIONS

Patients awaiting laminectomy or discectomy feared spinal surgery more than general anesthesia. This study also found that medical staff and surgeons play important roles in overcoming and reducing patient anxiety during the perioperative period.

Patient anxiety and modern elective surgery: a literature review

Medical advances have led to a considerable rise in the level of elective surgery undertaken as day-case surgery and with minimal hospital stay. However, amid such advances, preoperative psychological care has remained relatively static. A considerable number of patients are very anxious prior to elective surgery and little formal care is undertaken to address this major issue. A review of the literature from 1990 to 2002 was therefore undertaken in order to assess the present level of knowledge and interventions concerning patient anxiety when undergoing modern, intermediate surgical intervention. Thirty-four studies embracing data from 3754 patients undergoing both inpatient and day-case procedures were reviewed. Three main themes emerged - causes of anxiety, clinical concerns and measurement, and anxiety management. Each theme is discussed alongside details extracted from the relevant studies. Finally, the main issues arising are summarized and future research challenges identified.
