The Correlation Between Preoperative Anxiety and Postoperative Pain Perception in General Surgery Patients

Abstract

Introduction: Postoperative pain is a significant concern for surgical patients, impacting recovery, mobility, and overall satisfaction. While surgical technique and analgesic regimens are primary determinants, psychological factors, particularly preoperative anxiety, play a crucial, yet often underestimated, role in shaping the postoperative pain experience. Understanding this link is vital for holistic patient care in general surgery.

Literature Review: This literature review examines the strong association between preoperative anxiety and heightened postoperative pain perception in general surgery patients. It explores the intricate psychophysiological mechanisms, including central sensitization, increased sympathetic nervous system activity, and altered pain modulation pathways, which explain why anxious patients often report more severe pain. Studies consistently demonstrate that patients with higher levels of preoperative anxiety experience greater pain intensity, require more analgesia, and report lower satisfaction with pain control across various general surgical procedures. The review also discusses methods for assessing preoperative anxiety and the potential benefits of psychological interventions in mitigating this risk.

Conclusion: Preoperative anxiety is a significant and independent predictor of increased postoperative pain perception in general surgery patients. Given its pervasive influence on the pain experience, comprehensive preoperative anxiety screening and targeted psychological interventions are essential to improve pain management and overall surgical outcomes. Further research is needed to refine and standardize these interventions for broader clinical application.
