Filter by:The purpose of this study is to demonstrate superiority on postoperative bleeding from the use of a heparin half dose compared to a conventional dose, under mini-extra corporeal circulation, without increased risk to the patient.
The objective of this study is to evaluate the impact of reduced pump prime on blood transfusions and postoperative complications in patients at high risk of severe hemodilution during CPB. HYPOTHESIS The use of a new CPB circuit with a smaller internal volume, together with retrograde autologous priming of the lines (RAP) will allow a smaller prime volume and therefore less significant hemodilution on pump. EXPERIMENTAL DESIGN Overview Patients will be randomized on the morning of surgery to one of the two study groups in a 1:1 allocation scheme: 1. Low pump prime 2. Standard pump prime Outcomes The primary outcome is the number of units of blood products transfused within the first 24 hours post CPB.
The purpose of the present research study is to investigate for the first time, the safety and tolerability of infusion doses of AP214 in subjects having heart surgery such as coronary bypass graft and/or valve repair or replacement surgery. AP214, the investigational drug, is being developed to potentially prevent post-surgical kidney injury after thoracic aortic aneurysm repair.
The dept. of Anesthesiology currently has a database of subjects whom had surgery and received either Aprotinin or Amicar in the OR. The current viewpoint is that Aprotinin is more harmful than Amicard. In an effort to see what the long term outcomes were for subjects whom had surgery here at Upstate, it was decided to look at long term death rates to see if any differences. A student t-test will be used to determine statistical significance where a p value of <0.05 will be deemed significant. Using data from 462 subjects that had undergone cardiac surgery at SUNY Upstate Medical University, CABG only and the long term mortality rate from the Mangano, et.al. publications, the unadjusted mortality for the two drugs are Aprotinin 5.4% and Amicar 1.2%. A power analysis was performed using the hospital mortality rates of 5.4% and 1.2% with the sample size in the propensity data and a p-value of 0.05. The result was a power of 81.7%.
The purpose of this study is to determine whether the gentamicin-collagen sponge is safe and effective in preventing sternal wound infections in patients undergoing cardiac surgery who are at a greater risk of developing sternal wound infections.
To demonstrate that that the device is safe and potentially efficacious for use as a left ventricular cardiac assist device for postcardiotomy patients who require hemodynamic support post weaning from cardiopulmonary bypass.
Tranexamic acid is administered intravenously to prevent bleeding associated with cardiac surgery and cardiopulmonary bypass. We have developed an assay for tranexamic acid. We have developed an alternative dosing schedule for tranexamic acid. The objective of this preliminary study is to determine if this new dosing schedule can achieve the desired plasma concentration of tranexamic acid and reduce intra and inter patient variability in tranexamic acid plasma concentrations relative to the current dosing schedule.
Cardiac surgery is associated with pain in the post-operative period. We plan to conduct a study of local anesthetic, ropivacaine, infusion into the sternal wound in adult patients undergoing cardiac surgery to see if it will be safe and result in improved pain control and reduced time to extubation, duration of ICU and hospital stay.
Low output syndrome is a common complication in patients undergoing cardiac surgery. Its incidence was reported to be 2 to 6%. Morbidity and mortality of low output syndrome is high and the costs for treating the disease are immense.Natriuretic propeptide Type B (NT-proBNP) is a biological marker for the diagnosis, prognosis and therapy of cardiac failure after cardiac surgery. Cardiac index and NT-proBNP will be correlated with morbidity and mortality. A critical threshold value for intraoperative cardiac index and NT-proBNP will be calculated.
A total balanced fluid replacement strategy is a promising concept for correcting hypovolemia. The effects of a balanced fluid management including a new balanced hydroxyethylstarch (HES) in elderly cardiac surgery patients will be studied.
