The aim of this survey was to evaluate the routine use of ultrasonography during PPH. Methods A questionnaire, composed by a series of questions that assess participant characteristics and ultrasound use during PPH, was sent to members of the Italian Society of Ultrasound in Obstetrics and Gynecology currently employed in obstetrical units. Answers were subsequently grouped based on participant characteristics. Results Based on the responses of 200 participants it was found that ultrasound was routinely employed by 67 % of participants during PPH, by 85 % if Retained Products of Conception (RPOC) was suspected, by 67 % during Bakri balloon placement and by 69 % during curettage procedures. Routine ultrasound use was higher amongst participants working in hospitals with a higher number of deliveries, by those with more years of experience using ultrasound in labor, and by those that had attended specific postgraduate training courses. Conclusions Despite the lack of recommendations in the current guidelines, the results of this survey show that ultrasound seems to be commonly employed by maternal fetal medicine practitioners in the management of PPH.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":"74 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141870743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
