The effects of preoperative reactions of emotional distress on headache and acute low back pain after spinal anesthesia: A prospective study

Objectives: To address the effect of preoperative symptoms of depression and anxiety on headache and low back pain after spinal anesthesia. Methods: This prospective observational cohort study included 370 patients who underwent spinal anesthesia before elective surgeries at a university hospital. The patients were evaluated in terms of symptoms of depression (Beck Depression Inventory) and anxiety (Beck Anxiety Scale) while in their wards. The patients were evaluated via telephone calls for headache and low back pain after the operation. Results: Eighty-two (82/362) (23%) patients were determined as having headache and 28 (28/362) (7.8%) were determined as having low back pain. There was a significant association between preoperative depression scores and anxiety scores and VAS scores of headache (respectively, eta-squared = 0.19, p < .001; eta-squared = 0.14, p < .001). There was a significant association between preoperative depression scores and anxiety scores and VAS scores of low back pain (respectively, eta-squared = 0.02, p = .08; eta-squared = 0.03, p = .01). Conclusions: Preoperative symptoms of anxiety and symptoms of depression affect headache after spinal anesthesia. Preoperative symptoms of depression affect acute low back pain after spinal anesthesia. This trial was also registered at http://www.ClinicalTrials.gov. (Protocol Registration Receipt NCT03427372).
