Virtual reality (VR) pain distraction has been applied across medical, surgical, and behavioral healthcare domains, marking a shift in pain attenuation practices. However, there is little research that has been performed to compare the efficacy of traditional head-mounted displays (HMDs) versus portable VR devices. The present study evaluated 44 outpatients in need of lipoma resection. Randomized into two groups—HMD versus mobile phone VR—participants navigated pain distraction virtual environments while undergoing surgery. Vital signs and subjective pain measurements via a visual analog scale were taken before, during, and after the surgery. Results indicate that the HMD group reported greater pain reduction than the Mobile group. Overall, this study points to the efficacy of nonpharmacological pain attenuation practices. Although both systems reduced pain during surgery, the clinically validated VR environments seen in the HMD group were more effective. This study does show that inexpensive solutions can work in surgical settings. Future research should be performed to identify the most effective VR pain distraction systems.

The current report presents comparisons of pain reduction and heart rate response using supplemental virtual reality (VR) pain distraction between 22 indigenous and 22 urban patients during ambulatory surgery. Material and methods. Forty-four (44) patients participated under full informed consent. Half (n = 22) were indigenous peoples and half (n = 22) were urban patients (those residing in Mexico City). For the urban group, a surgeon performed ambulatory surgeries with local anesthesia to remove lesions in soft tissues, such as lipomas, cysts located in the head, neck, back, shoulders, arms, limbs, and abdomen. For the indigenous group, operating rooms, intravenous line, analgesics, and sedatives were not used. Materials included laptop-linked virtual reality, PlayStation, Smartphones and Google Cardboard googles alongside virtual environments such as Enchanted Forest, The Sea, Lake Valley, Jurassic Dinosaur and Coast Space VR. Results. Pain scale indicated 2.92 before, 1.67 during and 0.67 after for indigenous participants, and 5.8 before, 3.32 during and 1.48 after for urban participants. Heart rate responses in indigenous were 80.42(before), 78.5 (during) and 72.42 (after) and urban responses were 74.07 (before), 68.53 (during) and 73.1(after). Discussion. Indigenous patients presented more pain reduction during ambulatory surgery without intravenous lines, analgesics or sedatives and required recovery time or hospitalization. Supplemental VR during medical and surgical procedures is discussed in light of cultural, economic and psychological variables associated with medical care in Mexico. ©2019, Interactive Media Institute.
