Abstract

Background Preoperative anxiety is generally neglected in the evaluation of cardiac surgery patients due to various reasons including insufficient literature and lack of simple assessment tools. In addition to this, the association between anxiety and postoperative complications including pain has been scarcely studied. The present study was designed to assess preoperative anxiety levels in all patients coming for cardiac surgery and then evaluate the effect of different levels of anxiety on postoperative pain scores. Methods This prospective cohort study was conducted in a single university hospital from March 2018 to December 2019. One hundred consecutive cardiac surgery patients between the ages of 18-65 years were enrolled in this study. The level of preoperative anxiety (assessed by State Anxiety Inventory) and its effect on postoperative pain and morphine consumption was assessed. Results The average age of the patients was 58.24±10.03 years of which 68% were male and 32% were female. Preoperative mild anxiety was observed in 64% of patients and moderate to severe anxiety in 36% of patients. Post-operative mean pain score was significantly high in the moderate to severe anxiety group as compared to the mild anxiety group [Mean pain difference =1.64 (95%CI: 1.38-1.89) p=0.0005], [Mean pain difference =0.51 (95%CI: 0.29-0.73) p=0.0005] at 12 hours and 24 hours respectively. Intraoperative and postoperative morphine consumption was significantly high in patients with moderate to severe anxiety. Conclusions Patients with moderate to severe anxiety before cardiac surgery experienced higher pain scores at a post-operative period which is significantly different from the mild anxiety group. Intraoperative and postoperative analgesic requirements were also significantly increased.
