Background: After cardiac surgery, patients are often admitted to the intensive care unit (ICU) due to various preoperative factors and continue to receive mechanical ventilation. This study sought to conduct a bibliometric analysis to summarize studies on mechanical ventilation among postoperative ICU patients who had undergone cardiac surgery.
Methods: We searched the Science Citation Index Expanded (SCI-E) database using the following terms: "cardiac surgery (Topic)", "intensive care (Topic)" and "ventilation (Topic)". The search results were analyzed using R software. The analysis examined the number of publications of relevant articles and the annual change trend, the number of times an article was cited and the annual change trend, the distribution of countries conducting the research, the cooperation between countries and the citation frequency, the distribution of institutions conducting research, the cooperation between institutions, and the citation frequency, the number of published articles, the cooperation among researchers, and the citations frequency of researchers, the journals in which the articles were published, and the use of keywords.
Results: A total of 1,969 relevant research papers were included in this study. The main countries that conducted the relevant research included the United States (US), China, Germany, and Canada. The research institutions were mainly located in the US and Canada, and the main researchers were from research institutions in these countries. The most cited authors were Zappitelli, Hichey, and Wypij. According to Bradford's law, 9 core journals in this field were identified. The results of the keyword analysis showed that in the past 10 years, research has focused on the mortality of patients, but only a few related random controlled trials have been conducted.
Conclusions: More randomized controlled trials need to be conducted in this field to provide higher evidence-based medical evidence.

Rationale: Prior work has shown a preference among most people with dementia and their families for comfort-focused care near the end-of-life. Nonetheless, intubation and mechanical ventilation are increasing over time without concurrent trends in improved survival, including among those with advanced dementia. A better understanding of prehospital decision-making about intubation for people with dementia will guide efforts to increase goal-concordant care at onset of critical illness.

Background: Elevated intracranial pressure (ICP) is a potentially life-threatening condition requiring prompt intervention. While both mannitol and hypertonic saline (HTS) are commonly used hyperosmotic agents for treating elevated ICP, there is insufficient evidence comparing their renal safety profiles and overall effectiveness. This study protocol outlines a pragmatic randomized trial to compare protocol-based 11.

Department of Cardiac Surgery, Hôpitaux Universitaires de Strasbourg, Nouvel Hôpital Civil, Strasbourg, France.
Objective: This study investigated the efficacy of a multimodal analgesia (MMA) with an opioid-sparing strategy, incorporating a parasternal plane block (PPB) within a systematic standardized Enhanced Recovery After Surgery (ERAS) program for patients undergoing elective cardiac surgery.
Methods: From 2015 to 2021, 3153 patients underwent elective coronary artery bypass grafting and/or valve procedures. Patients were dichotomized by the presence or absence of an ERAS program including a perioperative MMA with an opioid-sparing approach and PPB protocols.

Division of Cardiac Surgery, Seattle Children's Hospital, Seattle, Wash.
Objective: To evaluate the effect of a blood conservation program on trends in use of donor blood products and early clinical outcomes in infants undergoing open heart surgery.
Methods: Four hundred nine patients younger than age 1 year undergoing open-heart surgery between October 1, 2020, and June 30, 2023, were reviewed. The study period was divided into 4 eras with the first era as a before blood conservation baseline using traditional blood management.
