Objective:To systematically analyze and integrate the real experience of puerpera in free delivery positions.Methods:Qualitative or mixed method studies on attitudes and emotional experiences of puerpera towards free delivery positions were retrieved through computer on PubMed, ScienceDirect, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, and WanFang Data. The search period was from database establishment to November 30, 2022. The quality of literature was evaluated using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center in Australia. The aggregation integration method was used to integrate the results.Results:A total of 5 articles were included and 28 results were extracted. The results were summarized into 10 categories, and 3 integrated results were formed, including factors that affected the choice of delivery position, the complex delivery experience of the puerpera, and the hope for much support.Conclusions:Hospitals, communities, and families should fully understand women's emotional experiences and needs for free delivery positions, provide sufficient support and guidance, and provide a reference basis for developing a reasonable delivery position plan and promoting a positive delivery experience.

Ventilator-associated pneumonia(VAP) is more likely to occur in patients with mechanical ventilation due to the decrease of oral self-purification ability, weakening of mucosal defense ability and translocation of oropharyngeal colonies. Oral care can reduce plaque and mucosal inflammation, improve oral function, promote oral health and effectively prevent VAP. This article reviewed the current situation of oral care for mechanical ventilation patients at home and abroad. Based on the best evidence, the evaluation of oral function, the choice of oral care solution and appliances were summarized. We suggested further improving the training system and unifying the evaluation, inspection standard and operation procedure, so as to develop the optimum oral care scheme.
