EVALUATION OF THE RELATIONSHIP BETWEEN PREOPERATIVE ANXIETY LEVELS AND INTRAOPERATIVE HEMODYNAMIC INSTABILITY IN ADULT PATIENTS UNDERGOING ELECTIVE SURGERY

Abstract

Background: Preoperative anxiety is a common emotional response experienced by patients before undergoing surgical procedures. Aim: To investigate the relationship between preoperative anxiety levels and intraoperative hemodynamic instability in adult patients undergoing elective surgery. Additionally, the study explored the impact of a history of cardiovascular disease on preoperative anxiety and its association with intraoperative hemodynamic instability. Methods: A total of 100 adult patients scheduled for elective surgery were included in this prospective observational study. Preoperative anxiety levels were assessed using the State-Trait Anxiety Inventory scale. Intraoperative hemodynamic parameters, including heart rate, blood pressure, oxygen saturation, were closely monitored during the surgical procedures. Statistical analysis, including Pearson correlation, chi-square, t-tests, were performed to evaluate the association between preoperative anxiety and intraoperative hemodynamic instability. Results: The mean preoperative anxiety score among the 100 patients was 35.2 (± 8.9) on the STAI scale. The majority of patients (n = 65) exhibited mild-to-moderate preoperative anxiety levels, while a smaller subset (n = 35) experienced high levels of anxiety. During the intraoperative period, 27% of patients experienced hemodynamic instability, characterized by fluctuations in heart rate, blood pressure, or oxygen saturation. Patients who experienced hemodynamic instability had a significantly higher average preoperative anxiety score of 42.8 (± 9.5) compared to patients without instability. Conclusion: This study provides evidence of a significant association between preoperative anxiety levels and intraoperative hemodynamic instability in adult patients undergoing elective surgery. Patients with higher preoperative anxiety scores, especially those above 40, were at a higher risk of experiencing hemodynamic instability during surgery.
