简要总结
This study evaluates the effect of virtual reality technology alleviates the acute pain of scar treatment with fractional laser under local anesthesia
详细描述
Fractional laser surgery under local anesthesia will accompany by the pain and anxiety. It's a bad experience for the patients. The effect of Virtual Reality (virtual reality, VR) to alleviate pain and anxiety of fractional laser treatment of scar is still not studied. Virtual reality technology is an important direction of simulation technology. Including the computer graphics technology, human-computer interface technology, multimedia technology, sensor technology, network technology and other collection technology. Usually generated by a real-time 3D animation of the computer system, a location tracker data. The handle and the head mounted display technology is commonly used in a variety of clinical invasive procedures, such as debridement and burn patients physical therapy, dental pain, injection pain, chronic itching. Previous study shows that VR as a distraction therapy, compared to the traditional methods ,for example watching video and listening to music, has stronger individual initiative and human-computer interaction, it shows a stronger analgesic effect.
HTC Vive is a VR headset, jointly developed by HTC company and Valve company. This equipment could improve the virtual reality experience and bring obvious analgesic effect. There are reasons to believe that HTC Vive could bring the best immersion experience and could be obviously decrease pain and anxiety of scar treatment with fractional laser under local anesthesia.
This study was conducted at department of burn, Changhai hospital, and all operations completed by experienced surgeons (researcher).
This study is a prospective randomized controlled study. A group of patients wear a blindfold and the other group treated with VR equipment (HTC Vive) after localized anesthesia with standard lidocaine cream. Finally, the differences of pain score,anxiety score, physiological indicators and satisfaction between two groups are compared. This study could provide a safe and non-drug intervention measure for patients receive fractional laser treatment under local anesthesia.

研究组 & 干预措施
Possess HTC Vive before the operation
The experimental group was wearing VR helmet before operation, and the immersion experience was selected from the video content library pre-selected. After 3 minutes of the VR experience, the surgeon started the fractional laser operation (Notify the patient). The operating area is continuous 10 maximum square spot areas.The parameters for the DEEP FX mode:35mj, 5% density, 300Hz.
干预措施: HTC Vive (Device)
Without HTC Vive before the operation
The control group was wearing a blindfold before operation. The operating area is continuous 10 maximum square spot areas. The parameters for the DEEP FX mode:35mj, 5% density, 300Hz.
干预措施: Without HTC Vive (Other)
