Filter by:The goal of this observational study is to assess in situ vascular function, glycocalyx and microcirculation in postoperative vasoplegic shock following cardiac surgery with cardiopulmonary bypass. The main question is to investigate the relationship between NO-dependent vasomotor reserve and the presence of vasoplegic shock following cardiac surgery with cardiopulmonary bypass. Participants will have two visits, during which a number of non-invasive examinations will be carried out to study glycocalyx, microcirculation and vascular function. Biological and morphological data will be collected up to 3 months after inclusion, as well as information on treatments administered and outcome. Researchers will compare a group of patients with vasoplegic shock against a group without vasoplegic shock in order to study possible alterations in function in the vasoplegic shock group.
The prevalence of iron deficiency in pediatric cardiac surgery patients is not very well known. Iron deficiency can lead to anemia, higher transfusion rates and possibly higher complication rates. In this retrospective study, the iron status of all patients undergoing pediatric cardiac surgery at our institution between January 2019 and december 2023 will be analyzed. Together with iron status, transfusion requirements as well as complications will be recorded. Iron status will be reported with descriptive statistics, patients with or without iron deficiency will be compared using non-parametric tests.
The goal of this clinical trialis to compare in learning effectiveness of nurses. The main questions it aims to answer are: 1. Can the "Micro-course" teaching enhance the awareness of cardiac surgery nursing among operating room nurses? 2. Can the "Micro-course" teaching boost the learning motivation and engagement of operating room nurses? 3. What is the satisfaction level of nurses regarding the use of "Micro-course" in cardiac surgery nursing? 4. What are the relevant factors influencing the effectiveness of the "Micro-course" teaching intervention? Participants will be divided into two groups. The control group will receive online presentations, while the experimental group will engage in mobile learning combined with micro-courses. Both groups of participants will undergo instruction through asynchronous online courses.
A previous audit (S63843) found an association between improved compliance with these interventions and postoperative outcomes (hospital length of stay (LOS) and presence of ≥1 postoperative complication). The investigators found that every 10% increase in compliance was associated with an increased risk (HR=1.25, p=0.0008) for early discharge. In addition, improved compliance was also associated with a reduction (OR=0.60, p=0.0003) of postoperative complications. Based on these findings, improving compliance with current guidelines remains a hurdle that clinicians should overcome. The investigators previous retrospective study was unable to identify the reason for non-compliance and the relation to postoperative outcomes. Therefore, a prospective audit is warranted to assess reach, fidelity, and dose of the different interventions.
This study intends to include hypertrophic cardiomyopathy patients over 18 years old who underwent cardiac surgery in our hospital. Patients were divided into medication group and control group according to the use of gastrodin during operation. The patients ' myocardial tissue samples were collected, the postoperative prognosis data were observed and recorded, and the data were analyzed. The degree of myocardial tissue cell damage and postoperative clinical outcomes were compared between the two groups.
The goal of this randomized controlled clinical trial is to compare effects of non-invasive ventilation with different modalities (notably CPAP and BIPAP) in patients undergoing heart surgery. The main question[s] it aims to answer are: - Which NIV ventilation mode is most effective in cardiac surgery patients? - Is there a big difference between conventional physiotherapy treatment and the use of NIV in these patients? Participants will be submited in the intervention will initially take place in the specific ward that receives patients in the postoperative period of cardiac surgery. Participants will be recruited after the patient is hospitalized the day before the surgery, during which time he will undergo a preoperative evaluation based on the study criteria. On that first day, the evaluation will consist of anamnesis and physical examination, focusing on the history of cardiac disorders, followed by measurements inherent to the protocol. Manovacuometry, chest X-ray, quality of life questionnaire, walk test and spirometry. The evaluation can be carried out in two stages, if there are other demands for the patient during his hospitalization. Researchers will compare three groups: 1 - cpap group - CPAP + usual physical therapy care, 2 - Bipap group - BIPAP + usual physical therapy care and 3 - Control - usual physical therapy care), in the 1:1 allocation ratio and superiority. to see if the effects of non-invasive ventilation with different modalities in patients undergoing cardiac surgery demonstrates some superior way in clinical practice. The observed outcomes will be: evaluation between NIV modalities, spirometry, lung capacity and vital signs. Secondary outcomes included are degree of satisfaction with the global perception of change scale, and MIF - functional independence measure and blood gas parameters.
On-pump coronary artery bypass graft (CABG) and valve replacement surgeries are high-risk procedures. Among the risk factors for postoperative complications, perioperative hyperglycemia and blood glucose variability have been reported to be associated with increased morbidity and mortality. The treatment of hyperglycemia using intravenous insulin infusion improves the prognosis in cardiac surgery patients. However, the determinants of postoperative blood glucose variability and the mechanisms leading to its deleterious impact are unknown. Thus, to date, there is no therapeutic intervention that could effectively prevent and treat the deleterious impact of glycemic variability on postoperative outcome. The purpose of the study is to evaluate whether perioperative alteration of the autonomic nervous system and preoperative blood glucose variability could be related to perioperative glycemic variability.
Platelet-rich plasma (PRP) is an autologous concentration of human platelets in a small volume of plasma. Because it is an autogenous preparation, PRP is inherently safe and therefore free from concerns over transmissible diseases such as HIV and hepatitis. Its power of regeneration already proved by orthopedics and dentists in their trials to regenerate cartilages .We will use it to know its ability to enhance healing of sternum in vulnerable patients to sternal dehiscence after open heart surgery .
The study compares safety and efficacy of the Del Nido cardioplegic solution, comparing it with the Buckberg cardioplegic solution in single aortic valve replacement procedures. Half the patients will receive the Del Nido solutions while the other half will receive the Buckberg solution.
This randomized, multi-center, double-blinded, placebo-controlled study is designed to evaluate the efficacy and safety of milrinone compared with placebo in participants after corrective surgery for congenital heart disease. Participants will be randomized in a 1:1 ratio within 90 minutes after arriving in the intensive care unit (ICU), to receive either intravenous milrinone or placebo for 36 hours. Participants will be stratified according Vasoactive Inotrope Score after arriving in the ICU.
