Objective:To retrieve, evaluate, and summarize the best evidence of early skin-to-skin contact after delivery, so as to provide guidance for medical and nursing staff to develop good maternal and infant services.Methods:Guidelines, evidence summaries and systematic reviews on the early skin-to-skin contact of newborns after delivery were searched in UpToDate Clinical Consultant, British Medical Journal (BMJ) , National Guideline Clearinghouse (NGC) , Registered Nurses' Association of Ontario (RNAO) , Scottish Intercollegiate Guidelines Network (SIGN) , National Institute for Health and Clinical Excellence (NICE) , Joanna Briggs Institute (JBI) , Cochrane Library, PubMed, EMbase, World Health Organization (WHO) professional websites and Chinese Biomedical Literature Database by computer. The search time limit was from the establishment of the database to November 30, 2019. Two researchers conducted evaluation and data extraction, and extracted evidence from literature that met the quality standards.Results:A total of 4 articles were included, including 2 guidelines and 2 systematic reviews. The evidence of early skin-to-skin contact of newborns after delivery mostly focused on the benefits of early mother-to-child skin-to-skin contact for newborns and mothers. The WHO clinical practice guidelines suggested that skin-to-skin contact should be made immediately after delivery for at least 90 minutes. This article summarized the evidence from three aspects, namely within 30 s after birth, 30 s to 3 min after birth, and within 90 min after birth.Conclusions:In clinical practice, midwives should focus on the health of newborns after delivery and implement newborn early contact management programs based on relevant evidence.

1.2 ng/ml on the third day as a threshold,the sensitivity,and specificity in predicting the prognosis of VAP were 81.0%,and 87.5%,respectively. CONCLUSIONS The results suggested that serum PCT be important for the diagnosis of VAP.PCT concentration over 1.2 ng/ml as a threshold is more sensitive and specific to distinguishing different outcomes.And the sensitivity and specificity of PCT are better than that of IL-6,IL-8.
