This systematic review was consequently performed to objectively investigate the analgesic effect of Oral GS related to NNS in newborns during nociceptive procedures. Methods： All potential records were searched in PubMed, Web of Science, EMBASE, and the Cochrane Library to capture the randomized controlled trials comparing GS with NNS in terms of pain scores in neonates through January 2017. Two independent investigators screened the identified articles, extracted the data, and assessed the methodological quality of the included studies. All statistical analyses were completed by using Review Manager （RevMan） version 5.3.0. Results： Four studies, involving 248 neonates, were incorporated into these statistical analyses. For reducing pain scores, no statistical difference was detected when GS compared to NNS （4 trials; mean difference [MD], 0.75; 95% confidence interval [CI], -0.77 to 2.27; P = 0.33）. Conclusion： Both the GS and NNS reduced the pain scores in neonates who undergoing Hepatitis B vaccination and venipuncture, but the NNS is more convenience than GS to some extent. Considered the limited evidences, more randomized controlled trials with high-quality, large-scale and appropriate measures time are warranted to further establish the comparative efficacy of these two options.展开更多
