Filter by:Adenosine has been proved to be an important mediator of myocardial protection induced by ischemic preconditioning. The hypothesis of this study is that adenosine preconditioning can provide additional myocardial protection in the setting of pediatric open heart surgery with cardioplegia and cardiopulmonary bypass.
The purpose of this study is to determine the predictors for placement of permanent pacemakers soon after cardiac surgery. We will measure the following to see what influence, if any, they have on predicting the need for permanent pacemaker implantation. 1. Type of cardiac surgery 2. Gender of patient 3. Patient's age 4. Preoperative heart rhythm and rate 5. Duration on cardiopulmonary bypass 6. Immediate post cardiopulmonary bypass heart rhythm and rate. 7. All heart rhythms and rates identified in the postoperative period prior to permanent pacemaker implantation. 8. Underlying heart rhythm and rates when permanent pacemaker is placed. 9. Ejection fraction before surgery 10. Ejection fraction immediately post-cardiopulmonary bypass
The goal of this study is to evaluate whether measures of the size of the internal jugular vein have clinical utility in predicting whether patients may benefit from treatment with intravenous fluid.
Blind randomized trial of a single bolus dose of dexmedetomine followed by a continuous infusion (CIVI) for up to 24 hours in infants who immediately post-operative from cardiac surgery and require tracheal intubation with mechanical ventilation in the post-operative period. Three bolus and infusion dose will be administered to a total of 36 patients.
This study is a blinded, randomized, controlled prospective trial comparing immune response (sepsis, inflammatory response, pulmonary vasoconstriction) in 2 groups of infants less than 3-month old receiving pre and post cardiopulmonary bypass surgery. The infants will receive 1 out of the 2 following intravenous lipid preparations: Soybean Oil (n-6), or a combination of Medium Chain Triglyceride i.e. coconut oil, Long Chain Triglyceride i.e. Soybean Oil, and Fish Oil (MCT:LCT:FO). There will be 16 subjects in each group.
Patients with or without diabetes may have high blood sugar levels due to stress response of the body during heart surgery. This study is being done to determine if maintaining normal blood sugar levels during open-heart surgery by using intravenous insulin results in a lesser incidence of death, wound infections in the chest, disturbances of heart rhythm, kidney failure, stroke and prolonged time on the breathing machine (artificial ventilation) within 30 days after surgery.
Patients with abnormal kidney function are at increased risk for complications following heart surgery, including worsening kidney function possibly requiring dialysis, a prolonged stay in the critical care unit and hospital, and the increased risk of death. Prior attempts at kidney protection for heart surgery patients have had mixed results. Two medicines, fenoldopam and N-acetylcysteine, have been shown to protect kidney function in other circumstances that cause kidney stress. The purpose of this study is to determine whether these medications will help to maintain the function of diseased kidneys during heart surgery.
