This clinical trial aims to investigate the effect of VR application on reducing preoperative anxiety and the intraoperative and postoperative pain of patients who undergo peritoneal dialysis catheter insertion. The main questions it aims to answer are: 1) Whether preoperative VR application can reduce preoperative anxiety in patients undergoing peritoneal dialysis catheter insertion; 2) Whether intraoperative VR application can reduce intraoperative and postoperative pain in patients undergoing peritoneal dialysis catheter insertion; 3) Whether VR application can improve patients satisfaction of the operation. Participants will be randomly assigned to the VR group and control group, and participants in the VR group will be introduced to VR use and watch a VR video about the operating room environment 1 day before the surgery. During the procedure, participants in the VR group will watch a soothing video through the VR device. In contrast, participants in the control group will receive the usual preoperative and surgical procedures. Preoperative anxiety, intraoperative and postoperative pain, and patient satisfaction will be compared between the two arms.

Peritoneal dialysis (PD) is an important alternative treatment modality for end-stage renal disease. Patients are required to undergo catheter insertion prior to PD. However, Patients undergoing catheterization for the first time often experience preoperative anxiety, and the procedure is usually performed under local anesthesia. Moreover, patients under local anesthesia are prone to significant intraoperative pain and poor surgical cooperation, which compromises the procedure and leads to low patient satisfaction. In recent years, virtual reality (VR) has been found to reduce preoperative anxiety and acute or chronic pain in medical fields such as pediatrics and dentistry. It is a non-invasive, accessible, safe, and effective modality. There is a lack of research on the use of virtual reality technology in peritoneal dialysis catheterization, so this study proposes to study the effect of VR application on reducing preoperative anxiety and intraoperative and postoperative pain in patients using VR before and during catheter insertion.

The study is a prospective, randomized, controlled, single-center study. Patients who meet the enrollment criteria will be randomly assigned to either the VR group or the control group. The VR group will be introduced to the use of VR and watch a VR video introducing the operating room environment 1 day prior to surgery, and play soothing audio/video via VR during surgery; the control group will undergo routine preoperative and surgical procedures. Preoperative anxiety, intraoperative and postoperative pain, and patient satisfaction will be assessed between the two groups.
