Abstract: Objective: To evaluate the effects of Virtual Reality (VR) on puerpera. Methods: A systematic search of Sinomed, VIP, CNKI, WanFang Data, EMBASE, PubMed, Web of Science, The Cochrane Library database, China Clinical Trials Registry and ClinicalTrials.gov was conducted to collect randomized controlled trials of VR applied to puerpera. The retrieved literatures were then screened and assessed by two researchers to extract relevant data for further Meta-analysis through software RevMan 5.3. Results: The study eventually enrolled 9 studies with a total of 853 subjects. Meta-analysis results showed that compared with traditional care interventions for childbirth, the rate of maternal cesarean section, anxiety score, the pain of cervix 9-10 cm dilated, and the pain during childbirth were significantly lower than those in the control group, but there was no statistically significant difference in the pain of cervix 4-6 cm dilated and the time spent in the first, second and third stage of labour. Conclusion: VR technology plays a positive role in parturient women during delivery. The promotion and popularization of VR technology can benefit patients.
