Methods: The RCT results were collected on children’s preoperative anxiety, anesthesia coordination, anesthesia and recovery agitation, postoperative pain and parental preoperative anxiety intervention with or without parental accompany using RevMan 5.3 software based on Chinese and English database. We searched Cochrane Library, Pubmed, Medline, EMbase, Sciencedirect, SpringerLink, China Biomedical, CNKI, Wanfang, Weipu and other databases, and included 15 articles (5 Chinese, 10 English) with 1390 samples size, containing 700 cases of control group and 690 cases of testing group. Results: Our results showed that parents’ and children’s anxiety level, the incidence of restlessness during anesthesia induction and wake-up period were reduced, while the anesthesia coordination was enhanced and the pain of children after wake-up was alleviated under parental accompany. Conclusion: The risk and cost-free intervention of parental accompany could be recommended as appropriate in hospitals for its contribution to children’s surgery effect.展开更多
