The Effects of a Virtual Rainforest and Portable Water Wall Application on Patient Satisfaction, Comfort, Anxiety, and Vital Signs Before Colonoscopy: a Randomized Clinical Trial

Abstract

Purpose: In this study, we used virtual reality glasses and a virtual rainforest (VRF) movie with natural sounds to create the impression of being in a peaceful VRF. We also used a portable water wall (PW) device that provides a natural appearance with irregular stones and light-emitting diode (LED) lights. The aim of this study was to investigate the effects of PW, an artificial natural water wall device, and VRF on patient anxiety, satisfaction, comfort, and vital signs before a colonoscopy procedure. Design: A double-blind randomized clinical trial. Methods: The study was completed with 135 participants (45 in the PW group, 45 in the VRF group, and 45 in the control group). Data were collected using the Patient Information Form, Vital Signs Record Form, and the State-Trait Anxiety Inventory. Findings: The study's findings demonstrated that, in both the PW and VRF groups, there were substantial increases in satisfaction, comfort, respiratory rate, and oxygen saturation levels, and significant decreases in anxiety, heart rate, and systolic and diastolic blood pressure (P < .05). The means of the variables in the control group before and after the surgery did not differ significantly (P > .05). Conclusions: According to the study results, precolonoscopy PW and VRF reduced anxiety, increased satisfaction and comfort, and had a positive effect on vital signs. The results of this study will contribute to evidence-based nursing practices for disturbances associated with colonoscopy. PWs’ sound and visual elements can have a calming and relaxing effect, and VR is a simple, affordable technology that can be used to provide patients better care. © 2025 The American Society of PeriAnesthesia Nurses
