Valencia, Spain | 16 - 18 May 2024 11th EORNA Congress ePosters 93 500 Intraoperative time out - Safe Surgery through a Multidisciplinary Timeout Naja Nielsen1, Thomas Korgaard Jensen2, Jakob Burcharth2, Lasse Rehné Jensen2 1Borgmester Ib Juuls Vej, Department of Anesthesia, Surgery, and Intensive Care, Herlev University Hospital, Herlev, Denmark, Herlev, Denmark, 2Borgmester Ib Juuls Vej, Department of Gastrointestinal Surgery, Copenhagen University Hospital Herlev, Herlev, Denmark: Emergency Research Group (EMERGE) Copenhagen, Copenhagen University Hospital Herlev, Herlev, Denmark, Herlev, Denmark Background: Surgical team’s decision-making in the intraoperative setting, including structured and systematic communication, is vital for ensuring patient safety and quality care. Hence, during critical surgeries, the complex and dynamic environment with possible time pressure, may further challenge well-functioned communication and the use of intraoperative timeout. Yet, the extent to which intraoperative timeout is used and widely implemented is incompletely understood Objectives: To explore the prevalence and applicability of using an intraoperative timeout during peroperative surgeries. Methods: We conducted a cross-sectional survey of operating room nurses’ use and knowledge about intraoperative timeout. In a collaborative working group of surgeons and operating room nurses, we performed an anonymous survey. Following pilot testing the survey, we distributed it among experienced operating room nurses from various surgical specialties, involved in the treatment of acute and unstable surgical patients. Data were collected from operating room nurses’ during the annual congress for operating room nurses’ in Denmark. Descriptive statistical analysis was conducted. Results: We had a response rate of 85% (n = 111). We identified four key areas related to the perioperative nurses’ experience of the communication structure: (1) 76% reported no additional timeouts during procedures, (2) 79% observed changes in surgical strategy during operations, (3) 31% noted the team’s response to strategy changes, and (4) 46% felt unable to suggest changes to senior surgeons. Conclusion: The study identified a tendency in Denmark to lack standardized intraoperative timeout for acute patients. Further research is needed to explore communication in the operating room and identify evidence-based needs. 505 Safe positioning at operation table, hip operation (posterior positioning) Mladen Levačić1 1Croatia Background: Posterior positioning in hip replacement refers to the surgical approach used to expose the hip joint during the procedure. The posterior approach is one of the most commonly used techniques, allowing excellent visualization of the acetabulum and femoral shaft. It is particularly popular for revision joint replacement surgery and cases where only the femoral component needs to be replaced. Posterior positioning in hip replacement surgery has both benefits and risks. Using a mini-posterior approach with a monoblock dual-mobility implant can achieve early hip stability. However, the posterior approach may have a higher dislocation rate in certain patient populations, such as demented or elderly bedridden patients who lie in a flexed and adducted position. Objectives: This review aims to give a comprehensive picture of the benefits and risks of posterior positioning in hip replacement, based on the latest scientific data. Conclusion: Posterior positioning in hip replacement surgery has benefits such as stability and patient satisfaction, but it also carries risks of dislocation and complications. Preserving the piriformis muscle in the posterior approach for hemiarthroplasty can significantly reduce the risk of dislocation and reoperation rates. When it comes to higher dislocation rates in certain patient population, proposed are modifications that aim to combine the advantages of the posterior approach with greater stability and they have been shown to provide better outcomes. There is a need for further research into the possible benefits and risks of using posterior positioning.
