OBJECTIVE: The aim of this study is to evaluate the effects of positive intervention on the anxiety and the physiological and psychological aspects among preoperative and post-surgical patients with spinal anesthesia.

PATIENTS AND METHODS: A randomized trial was conducted with an intervention group (n=58) and a control group (n=59). In the intervention group, the patients were well-informed of the details during spinal anesthesia. Multiple methods were performed to control anxiety before surgery, and nurses were not allowed to discuss the condition during surgery. Anesthesiologists were invited to visit patients to avoid excessive anxiety.

RESULTS: The intervention group showed lower scores of State-Trait Anxiety Inventory (STAI) (p<0.05) than the control group 24 hours post-operation. Physiological indices such as systolic blood pressure, low frequency (LF) power, high frequency (HF) power and ration of LF/HF showed better surgery recovery (p<0.05) than the control group. The length of post-anesthesia care unit stay was also significantly shortened in the intervention group (p=0.001) compared with the control group. Positive intervention may alleviate the anxiety in surgical patients receiving spinal anesthesia and improve the physiological and psychological outcomes clinically.

CONCLUSIONS: Our results provide evidence indicating that proper intervention can be promoted clinically to improve the satisfaction and quality of life of patients undergoing spinal anesthesia.
