Effect of a Nursing Intervention Based on Stress Adaptation Theory on Stress Status in Patients Undergoing Diabetic Retinal Laser Surgery: A Randomized Controlled Study
Effect of a Nursing Intervention Based on Stress Adaptation Theory on Stress Status in Patients Undergoing Diabetic Retinal Laser Surgery: A Randomized Controlled Study
This randomized controlled study evaluated whether a nursing intervention based on stress adaptation theory could improve pain trajectory and procedural tolerance in patients undergoing ambulatory retinal laser photocoagulation for diabetic retinal disease. Patients were randomized to receive either routine peri-procedural care or routine care plus a structured nursing intervention including a brief treatment pause, guided slow breathing, anticipatory communication, real-time reassurance, and post-procedure observation. Outcomes included pain intensity, physiologic responses, procedural cooperation, and adverse events.
Retinal laser photocoagulation remains an important treatment for diabetic retinal disease, but the procedure may cause pain, physiologic stress, and adverse reactions that reduce treatment tolerance and cooperation. This study was designed to evaluate a nursing intervention based on stress adaptation theory in patients undergoing diabetic retinal laser surgery. Participants were randomized to an intervention group or a control group. The intervention group received structured peri-procedural nursing support aimed at reducing stress and improving adaptation during the most painful phases of treatment. The control group received routine care. The primary outcome was pain intensity measured at four peri-procedural time points. Secondary outcomes included peripheral oxygen saturation, heart rate, respiratory rate, blood pressure, procedural cooperation, and adverse events.
