Virtual Reality and Cryotherapy for Postoperative Pain and Anxiety After Cesarean Section

Cesarean section is one of the most commonly performed surgical procedures worldwide. Despite advances in perioperative care, many women continue to experience moderate to severe postoperative pain and anxiety, which can negatively affect early mobilization, breastfeeding, maternal-infant bonding, and overall recovery. Although pharmacological analgesia remains the standard of care, non-pharmacological interventions may provide additional benefits while minimizing medication-related adverse effects.

Virtual reality is an immersive distraction technique that has shown promise in reducing pain perception and anxiety in various clinical settings. Cryotherapy is another non-pharmacological intervention that may reduce pain through local cooling, decreased nerve conduction velocity, and reduced inflammatory responses. However, evidence regarding their combined effectiveness after cesarean section remains limited.

The purpose of this randomized controlled trial is to evaluate the effectiveness of virtual reality and cryotherapy, individually and in combination, on postoperative pain and anxiety among women undergoing cesarean section under spinal anesthesia. Eligible participants will be randomly allocated to the study groups according to the trial protocol. Pain and anxiety outcomes will be measured using validated assessment instruments at predefined postoperative time points. The primary outcomes are postoperative pain intensity and anxiety. The results are expected to contribute to evidence-based postoperative nursing care by identifying effective, safe, and feasible non-pharmacological interventions for women undergoing cesarean section.
