[Nasal irrigation with different concentrations of saline as an adjunctive treatment in allergic rhinitis:A systematic review and Meta-analysis].

To compare the clinical efficacy of different concentrations of saline irrigation in adjuncative treatment of allergic rhinitis by Meta-analysis. According to the inclusion and exclusion criteria, the studies using random controlled trials were retrieved from the Pubmed, Web of science, The Cochrane Library, Embase et al. The Mata-analysis was performed by using RevMan 5.3 software. In total, 1 457 patients were enrolled in 14 randomized controlled trials, including 739 in the isotonic saline group, 350 in the hypertonic saline group,Times New Roman 368 without saline irragation. The results of Meta-analysis showed that the VAS score of saline irrigation group was lower than no saline irrigation group［95% (-1.57, -0.15), =0.02］, the nasal RQLQ score was lower［95% (-3.93, -0.43), =0.01］, and the effective rate was higher［95%(1.15, 1.45), <0.01］; The score of nasal symptoms and signs in hypertonic saline group was lower than that in normal saline group［95%(-1.68, -0.63), <0.01］, and the effective rate was higher［95%(1.19, 1.47), <0.01］. There were significant differences between the two groups. The efficacy of saline irrigation as an adjunctive treatment in allergic rhinitis is significant. The effect of hypertonic saline irrigation was better than that of isotonic saline.
