The impact of continuous haemofiltration with high-volume fluid exchange during cardiopulmonary bypass surgery on the recovery of patients with impaired renal function: a pilot randomised trial

Background: The use of haemofiltration is widely used in clinical practice in cardiac surgery units around the world. The primary pilot trial objectives were as follows: to assess the likelihood and safety of our chosen outcome measures; to investigate issues that may have an effect on recruitment into a formal trial; and to perform an exploratory economic analysis. Between November 2010 and March 2012, the Liverpool Heart and Chest Hospital NHS Foundation Trust was set up by the Liverpool Heart and Chest Hospital NHS Foundation Trust. Participants: Men and women, aged > 18 years of age, under on-pump CABG surgery, who had pre-operative impaired kidney function, were estimated by an estimated glomerular filtration rate of 3 days and the length of ICU stay days. Patients who underwent intraoperative haemofiltration were prone to reduced length of ICU stay, particularly those with diabetes. The findings of this pilot research are very encouraging, and they reveal that a continual superiority trial with the length of ICU stay days or time to tracheal extubation as the primary outcome measure, provided that guidelines on avoiding bias are implemented. The inclusion criteria should also be expanded to include all cardiac surgery patients with impaired renal function. Funding: This project was funded by the NIHR Health Technology Assessment service and will be published in full in Health Technology Assessment; Vol.

Comparison of New Technology Integrated and Nonintegrated Arterial Filters Used in Cardiopulmonary Bypass Surgery: A Randomized, Prospective, and Single Blind Study

Patients who underwent coronary bypass surgery were randomized into integrated and nonintegrated arterial line filter groups. In Group NIn, the prime volume was noticeably higher, and mean intraoperative hematocrit value was lower, but Group NIn's demand for erythrocyte transfusion was significantly higher, but not so high in Group NIn. Except for postoperative second day's results, which were significantly lower in Group In than in Group NIn, C-reactive protein values did not change significantly, except for postoperative second day's findings, which were significantly lower in Group In than in Group NIn. In Group In, Intraoperative hematocrit levels were higher, and the need for postoperative erythrocyte transfusion was reduced.

Outcome of inflammatory response after normothermia during cardiopulmonary bypass surgery in infants with isolated ventricular septal defect

MethodsOf the 212 infants with isolated ventricular septal defect who underwent open heart surgery between January 2001 and December 2010, 43 infants were recruited. Results show no significant differences between the two groups at the time of the OHS, group 1, infants undergoing hypothermic CPB and group 2, infants undergoing near-normothermic CPB. The CPB's time and ACC clock in group 1 were longer than those in group 2 compared to those in group 2. Additionally, no postoperative variations were found between the two groups in terms of white blood cell count and C-reactive protein levels in neonates and infants treated for simple congenital heart disease, according to this research.

Is serum cystatin C an early predictor for acute kidney injury following cardiopulmonary bypass surgery in infants and young children?

Following cardiopulmonary bypass surgery in infants and young children with congenital heart disease, acute kidney injury is a potential complication. After pediatric CPB surgery, the new pilot study examines the predictive value of serum cystatin C for AKI. Serum CysC was measured at baseline and at 6 hours, 12 hours, 24 hours, and 48 hours after initiation of CBP. After heart surgery, twenty-one patients developed AKI. Children with AKI required more sophisticated cardiac surgical interventions, a longer CPB cycle, and a longer aortic clamping time were among the AKI's that were affected by AKI. With an area under receiver operating characteristic curve value of 0. 69, the highest predictive results were achieved 6 hours after CPB with an area under receiver operating characteristic curve value of 0. 69. In summary, serum CysC had limited predictive capacity and was not compatible with clinical risk factors for the early detection of AKI after CPB surgery in this pilot study, which focused on infants and young children.

A randomized comparative study of patients undergoing myocardial revascularization with or without cardiopulmonary bypass surgery: The MASS III Trial

The MASS III Trial is a large initiative undertaken by a single institution, The Heart Institute of the University of Sao Paulo, Brazil, enrolling patients with coronary artery disease and preserved ventricular function. Both plans were tested during the MASS III trial to compare medical efficiency, cerebral pain, quality of life, and the cost-effectiveness of coronary surgery with and without cardiopulmonary bypass in patients with multivessel coronary disease. In a subset of patients using the Brain Resource Center computerized cognition database, a neurocognitive evaluation will be performed. In addition, magnetic resonance imaging will be used to determine any cerebral injury before and after cardiac catheterization in patients undergoing coronary artery bypass and those without cardiopulmonary bypass. Registration of Clinical Trials Patients with Stable CAD MASS III are eligible for trials. ISRCTN59539154 Off-pump surgery in patients with a stable CAD MASS III is a result of a study conducted by the authors.

Isolated Human Pulmonary Artery Structure and Function Pre‐ and Post‐Cardiopulmonary Bypass Surgery

It's unclear if human pulmonary arterial function is impaired. The goal of the present research was to compare the physical appearance and function of isolated and cannulated human pulmonary arteries obtained from lung biopsies after the chest was opened to those obtained after coronary artery bypass surgery in patients undergoing coronary artery bypass graft surgery. Methods and ResultsPrepare and ResultsPrecedent and Post-cardiopulmonary bypass lung biopsies were collected from 12 patients undergoing elective surgery. In most arteries, smooth muscle cells aligned circumferentially; live cell viability revealed that although 100% of smooth muscle and 90 percent of endothelial cells from pre-cardiopulmonary bypass biopsies had intact membranes and were considered viable, only 60 percent and 48 percent were viable from post-cardiopulmonary bypass biopsies, respectively. Conclusions We were able to determine isolated pulmonary artery structure and function in fresh lung biopsies from patients undergoing heart surgery.

Modified Glucose‐Insulin‐Potassium Regimen Provides Cardioprotection With Improved Tissue Perfusion in Patients Undergoing Cardiopulmonary Bypass Surgery

In patients undergoing cardiopulmonary bypass surgery, this analysis sought to examine the effects of a modified GIK regimen administered perioperatively with an insulin-glucose ratio of 1:3 in patients undergoing cardiopulmonary bypass surgery. Methods and Results In this prospective, double-blinded trial of 930 patients referred to cardiac bypass, GIK, or placebo therapy, it was administered intravenously at 1 mL/hour for 10 minutes before anesthesia and continuously for 12. 5 hours. With positive resuscitation, congestive heart failure, and arrhythmia, the primary result was the incidence of hospital major adverse cardiac events, including all-cause mortality, low cardiac output syndrome, acute myocardial infarction, cardiac arrest with prompt resuscitation, congestive heart failure, and arrhythmia. Compared to the control group, GIK therapy reduced the incidence of major adverse cardiac events and improved cardiac function recovery without raising perioperative blood glucose levels. During cardiopulmonary bypass surgery, systemic blood lactate levels were also reduced in GIK-treated patients.

Lack of Efficacy of Ulinastatin Therapy During Cardiopulmonary Bypass Surgery

Background: It was thought that inflammatory response triggered by cardiopulmonary bypass was to blame for cardiac arrests. The aim of this research was to determine the effect of ulinastatin on post-CPB surgery. Methods: Essentially, 208 patients who underwent elective valve replacement between November 2013 and September 2014 were divided into Group U and Group C based on whether they had UTI or not. Participants were compared between groups using Fisher's exact measurement and continuous variables using unpaired Student's t-test or Mann–Whitney U-test. After being adjusted by multivariable logistic regression and the propensity score, UTI still cannot be able to increase any outcomes after cardiac surgery. Also, there are no statistical differences between the duration of postoperative mechanical ventilation, the length of the Intensive Care Unit, and hospital stays. After cardiopulmonary bypass surgery, UTI did not improve postoperative outcomes in our patients.
