The Effect of Virtual Reality Glasses Used During Chest Tube Removal Following Open- Heart Surgery on Pain and Hemodynamic Parameters: A Randomized Controlled Trial
This randomized controlled trial demonstrates that using virtual reality glasses during chest tube removal following open-heart surgery significantly reduces pain levels and improves peripheral oxygen saturation without altering other hemodynamic parameters, supporting its efficacy as a non-pharmacological nursing intervention.

Recovering from open-heart surgery is a journey that demands immense physical resilience. While the heart itself has been repaired, the body must still heal from the large incision made to reach it and the tubes left inside to drain fluid and air. One of the most difficult moments in this recovery is the removal of those chest tubes. The procedure is brief, but it is widely known to be intensely painful. This pain is not just a matter of comfort; it triggers a chain reaction in the body. When a patient feels sharp pain, their nervous system often reacts by speeding up the heart and raising blood pressure, much like a sudden jolt of adrenaline. For a heart that has just undergone major surgery, this extra stress can be risky. Doctors and nurses have long sought ways to manage this pain without relying solely on strong medications, which can sometimes cause side effects or fail to fully calm the patient.
In a recent study, researchers explored a modern solution to this age-old problem: virtual reality. This technology immerses a person in a computer-generated world, effectively pulling their attention away from their physical surroundings. The idea is that if the brain is busy processing a peaceful, three-dimensional scene, it has less capacity to register pain signals. To test this, a team of researchers in Turkey conducted a controlled experiment involving eighty-two patients who had recently undergone open-heart surgery. The goal was to see if wearing virtual reality glasses during the removal of chest tubes could lower the pain patients felt and keep their vital signs, such as heart rate and blood pressure, more stable.
The study took place in a university hospital, where patients were divided into two groups. One group received the standard care they would normally get during the procedure, while the other group wore virtual reality headsets. These headsets were connected to smartphones playing a specific video: a calm, relaxing walk through a forest. The patients in the virtual reality group began watching this video five minutes before the tube was pulled and continued for five minutes after the procedure was finished. The control group sat in the same position and received the same medical care, but without the visual distraction. Throughout the process, the medical team carefully measured how much pain the patients reported and tracked their blood pressure, heart rate, breathing, and oxygen levels at several points in time.
The results showed a clear difference in how the two groups experienced the event. Patients who wore the virtual reality glasses reported significantly less pain immediately after the tube was removed and five minutes later, compared to those who did not wear the glasses. While both groups felt the sharp sting of the procedure, the virtual reality group described the sensation as much milder. This suggests that the immersive forest walk successfully distracted the patients' brains, dampening the intensity of the pain signal. However, the effect on pain was not permanent; by fifteen and thirty minutes after the procedure, the difference in pain levels between the two groups had faded, indicating that the relief was strongest during and shortly after the distraction.
Beyond pain, the researchers also looked at how the procedure affected the patients' physical stability. When the chest tube was removed, the patients' bodies naturally reacted with a stress response. In the group without virtual reality, this reaction was more pronounced, with a noticeable drop in oxygen saturation levels right after the tube came out. In contrast, the patients wearing the virtual reality glasses maintained higher oxygen levels immediately following the procedure. This suggests that by reducing the pain and the associated panic or shallow breathing, the virtual reality experience helped the body stay more balanced. While the technology did not completely stop the rise in heart rate or blood pressure that naturally occurs with pain, it did help keep oxygen levels more stable, which is a critical factor for heart patients.
The study concludes that using virtual reality glasses is a safe and effective way to help patients cope with the intense pain of chest tube removal. It offers a non-drug alternative that can make a difficult medical moment more bearable and support the body's natural stability. The researchers noted that while the pain relief was most effective in the short term, the immediate benefit to oxygen levels is a significant finding. This approach does not replace the need for medical care, but it adds a valuable tool to the nurse's toolkit, allowing patients to face a painful procedure with less distress and a more stable physical response. As digital health tools become more common, this study provides evidence that simple, immersive experiences can have a tangible, positive impact on the physical recovery of the heart.
