Filter by:Dexmedetomidine, an alpha-2 agonist, is a sedative that is widely used in various clinical settings because, compared to benzodiazepines, it preserves respiratory function better and its duration of action is short. Recent experimental studies showed a possibility that dexmedetomidine may have an organoprotective effect from ischemic-reperfusion injury by reducing inflammatory response. Besides, dexmedetomidine is known to be related with attenuated sympathetic tone and improved microcirculation. Taken together, it is plausible that dexmedetomidine exerts cardioprotection in patients undergoing cardiac surgery with cardiopulmonary bypass and aortic cross-clamp. The aim of this trial is to test the effect of dexmedetomidine on postoperative cardiac troponin I measurements in patients undergoing cardiac surgery.
TRICS-IV is an international, multi-centre, open-label randomized controlled trial of two commonly used transfusion strategies in moderate to high risk patients who are 65 years of age or younger undergoing cardiac surgery on cardiopulmonary bypass, using a superiority trial design.
The purpose of this study is to compare the values of Surgical Pleth Index (SPI) and Nociception Level Index (NOL) measured simultaneously during cardiac surgery.
A randomized, parallel group, active comparator-controlled trial to evaluate the non-inferiority or superiority of Cryopreserved Platelets with Liquid Stored Platelets in controlling blood loss in patients undergoing Cardiopulmonary Bypass Surgery.
The aim of this study is to examine effects of dental treatments, surgical (extractions) and non-surgical procedures (non-surgical periodontal therapy), on serum levels for PCR, WBCs and PCT in patients needing a dental remediation before undergoing cardiac surgery.
1. To evaluate the consistency of cardiac output measured by pulmonary artery catheter and LiDCO in cardiac surgical patients 2. To evaluate whether different hemodynamic monitoring methods can accurately detect the trend of cardiac output changes
Objective: To assess the predictive value of dynamic tests and parameters for evaluation of fluid responsiveness after off-pump coronary artery bypass grafting (OPCAB). After arrival to ICU, all patients received positive end-expiratory pressure test (PEEP-test), mini-fluid challenge test (mFCT) and standard fluid challenge test (sFCT) to assess fluid responsiveness. In addition, investigators measured pulse pressure variation using two monitoring systems (PPVPiCCO and PPVNK), stroke volume variation (SVV), heart-lung interaction index (HLI) and plethysmogram variability index (PVI) before and after sFCT.
Research objective: (1) To develop a minimally invasive extracorporeal circulation integrated system, and to form a new product package, the package of the system should include the extracorporeal circulation off-set supplies for a routine heart operation.(2) To explore the influence of integrated minimally invasive extracorporeal circulation system on the recent clinical outcome of patients.(3) To explore the influence of integrated minimally invasive extracorporeal circulation system on blood dilution of patients.(4) To explore the influence of integrated minimally invasive extracorporeal circulation system on inflammatory response in patients. 1) Clinical research methods: A prospective, single-blind, randomized controlled study was designed. 80 patients should be included.Clinical study grouping: The control group was conventional cardiopulmonary bypass (CCPB) group, which was equipped with ordinary oxygenator, microemboli filter and 4:1 cardioplegia solution.The experimental group was minimal invasive cardiopulmonary bypass (MICPB) group, with built-in micro-thrombotic oxygenator and mini cardioplegia (MP) formula (15ML15% potassium chloride (KCl)+10ml compound potassium, calcium and magnesium +25ml normal saline). Research method: A: Before, in, and after cardiopulmonary bypass (CPB) blood collection, Hemoglobin (Hb), hematokrit (Hct), and blood lactate values of the two groups of patients were measured and analyzed statistically.B: Blood transfusion volume, urine volume and ultrafiltration volume were collected during CPB in the two groups of patients, and the data of the two groups were statistically analyzed.To investigate the effects of integrated minimally invasive extracorporeal circulation system on inflammatory response indicators white blood cell count (WBC),C-reactive protein (CRP), interleukin-6(IL-6), tumor necrosis factor-a (TNF-a) and C3a in patients before (T0), CPB (T1) and 2 hours(H) after CPB (T2), blood samples were collected from the two groups, centrifugated, superfluid was taken, and stored at -80℃.The concentrations of CRP, IL-6, TNF-a and C3a were determined by ELISA.Statistical analysis was performed.WBC was measured in blood routine.(3) To investigate the influence of integrated minimally invasive extracorporeal circulation system on the recent clinical outcome of patients. The mechanical ventilation time, ICU time, length of hospital stay, and in-hospital mortality of patients in the two groups were statistically analyzed.
The purpose of this study is to assess efficacy of erector spinae plane block (ESP) for postoperative pain management in cardiac surgery patients.
Acute Kidney Injury (AKI) is a common serious complication after cardiac surgery. AKI not only prolongs the hospitalization time of patients undergoing cardiac surgery and increases the cost of treatment, but also is an independent risk factor for postoperative death. The aim of this study is to investigate the outcome of patients treated with renal replacement therapy (RRT), and to evaluate the short-term and long-term outcomes of patients with RRT.
