Emotional Stress and Immune Response in Surgery: A Psychoneuroimmunological Perspective

Psychoneuroimmunology (PNI) offers a deep dive into the nexus between emotional stress, immunity, and surgical outcomes. In this narrative review, we first trace PNI's historical roots, providing a foundational understanding of its evolution. We then dissect its significance across the surgical journey, from the preoperative phase through to postoperative recovery. It becomes evident through our exploration that emotional stress has profound implications for surgery, notably influencing wound healing rates, susceptibility to infections, and overall postoperative well-being. Among the arsenal to combat these challenges, interventions such as cognitive-behavioral therapy, mindfulness, and complementary practices such as meditation and yoga have emerged as potent tools. They not only mitigate stress but also play a pivotal role in enhancing immune function. However, the journey to optimizing surgical outcomes is not just about identifying effective interventions. A resounding theme is the importance of holistic care, ensuring that all patients have equitable access to these tools. As PNI continues to evolve, we stand at the precipice of a healthcare revolution, one that promises a blend of personalized care, anchored in a deep understanding of the mind-body connection in surgical contexts.
