Postural Mobilization Compared to Noradrenaline Only in Off-Pump CABG Surgery

This interventional prospective randomized study is designed to compare hemodynamic management using postural mobilization (+/- noradrenaline) versus noradrenaline only in patients undergoing open-heart coronary artery bypass graft (CABG) surgery.

The Role of Swan-Ganz Catheter in Hemodynamic Resuscitation for Patients With Cardiogenic Shock

This clinical trial examines whether the use of the Swan-Ganz catheter, a specialized pulmonary artery catheter, can improve hemodynamic management and treatment outcomes in patients experiencing cardiogenic shock due to acute myocardial infarction (AMI). Cardiogenic shock is a critical condition marked by the heart's inability to supply adequate blood to the organs, often resulting from a severe heart attack. Despite advancements in care, the condition remains associated with high mortality. Effective monitoring of cardiovascular status is crucial in guiding timely and tailored treatment decisions. Participants in this study will undergo advanced hemodynamic monitoring using the Swan-Ganz catheter, which provides continuous data on cardiac output and other key parameters. This information enables physicians to better assess circulatory function and adjust therapies accordingly. The research will evaluate clinical characteristics, response to treatment, and 30-day outcomes in patients managed with this technique. The study also aims to identify factors associated with successful hemodynamic stabilization and potential complications related to catheter use. A total of 108 adult patients meeting specific eligibility criteria will be enrolled at Bach Mai Hospital over 3 years. Participation is voluntary, and all patients will continue to receive standard-of-care treatment. All personal and medical data will be handled with strict confidentiality.

Goal-directed Hemodynamic Management and Kidney Injury After Radical Nephrectomy or Nephroureterectomy

Radical nephrectomy and nephroureterectomy are common operations for the treatment of renal cell carcinoma and upper tract urothelial carcinoma, respectively. However, acute kidney injury frequently occurs after surgery. And the occurrence of acute kidney injury is associated with an increased risk of chronic kidney disease. Intraoperative hypotension is identified as an important risk factor of postoperative acute kidney injury. Preliminary studies showed that goal-directed hemodynamic management may reduce kidney injury after surgery but requires further demonstration. We hypothesized that goal-directed hemodynamic management combining hydration, inotropes, and forced diuresis to maintain pulse pressure variation \<9%, mean arterial pressure ≥85 mmHg, and urine flow rate \>200 ml/h (3 ml/kg/h) may reduce the incidence of acute kidney injury and improve long-term renal outcome after radical nephrectomy or nephroureterectomy. The purpose of this study is to investigate the effect of goal-directed hemodynamic management on the occurrence of acute and persistent kidney injury in patients following radical nephrectomy and nephroureterectomy.

Effect of Reduced Vasopressors on Mortality in ECMO-supported Cardiogenic Shock Patients

The goal of this observational study is to learn about the association between vasopressor exposure levels and outcomes in adults with cardiogenic shock receiving VA-ECMO. The main question it aims to answer is: Does reduced exposure to vasopressors lower the 30-day mortality in patients with cardiogenic shock when receiving ECMO support? Participants who are receiving ECMO support for cardiogenic shock as part of their regular medical care will have their data collected, including information about their vasopressor use and mortality outcomes, over the course of the study.
