From March 2018 to February 2019, 40 subjects were enrolled, randomized, and completed the study; 19 were randomized to control and 21 to the VR arm. Most baseline characteristics were similar between groups. For the primary outcome, those assigned to the control arm had a statistically significant increase in pain of +0.58, while the VR arm had a significant reduction in pain of -0.52 (p = 0.03). There was also a difference in the proportion who had a minimum clinically important difference in pain.
In this study, authors show that VR uses is very efficient to reduce pain for laboring women. VR allows also to reduce the need of drugs like hydromorphone.
