Filter by:To investigate the influence of PEEP (Positive end-expiratory pressure), changes in preload (patient position) and changes in afterload (phenylephrine) on ultrasound measures of renal perfusion in patients after uncomplicated cardiac surgery. To investigate the effects of phenylephrine on both invasive measures of the systemic- and pulmonary circulation and, secondarily, to assess the induced changes in echocardiographic indices of left- and right ventricular systolic- and diastolic function.
Patients who undergo cardiac surgery will be screened by a team member with the risk score once the patient has been admitted to the Cardiovascular Progressive Care Unit (CVPCU) after surgery. Participants will be randomized to the intervention or the control group. Both groups will receive standard discharge planning. In addition, the intervention group will have a nurse practitioner (NP) who will be responsible to verify that each essential step of the discharge process has been completed and will visit the patient in patient's home after discharge to complete a physical, review medications, titrate medications as needed, prescribe any necessary treatments, and perform education. The primary outcome variable will be a decrease in the 30 day readmission rate comparing high risk patients at pre and post intervention.
The application of acute Normovolemic Hemodilution in cardiac surgery can effectively reduce perioperative blood transfusion, reduce postoperative complications and mortality, and is a low-cost, operable and effective blood protection measure.For the application of Acute Normovolemic Hemodilution in heart surgery, we still face an urgent problem: to what extent can Acute Normovolemic Hemodilution achieve better "blood saving effect", that is, whether a large number of Acute Normovolemic Hemodilution can reduce perioperative blood transfusion to a greater extent
This study will describe and explore the recovery process of patients undergoing cardiac surgery during the covid-19 pandemic. This will include mortality, morbidity, health-related quality of life, event-specific distress and depression.
This randomized controlled trial study aims to examine the effects of a multidimensional exercise program in cardiac surgery patients. The following hypotheses were tested: patients who received the exercise program will report significant improvement in frailty after the 12-week multidimensional exercise program. Subjects are randomly assigned to the intervention or control group. Patients in the intervention group will receive a 12-week multidimensional exercise program. Data are collected by using medical records and structural questionnaires, measuring handgrip strength, and a four-meter walk test at baseline, 6 weeks, and 12 weeks.
The primary objective is to test the efficacy and safety of the accuracy of continuous intravenous infusion of norepinephrine during cardiopulmonary bypass (CPB) on the prevention of hyperlactatemia after cardiac surgery. "Efficacy" would be tested with measurement of the postoperative changes in lactic acid level over time from the baseline value before induction of general anesthesia. "safety" would be tested with observing the post-cardiotomy need for inotropic and vasopressor support, the incidence of postoperative acute kidney injury (AKI), changes in cardiac troponin level (CnTnI), and signs of ischemic splanchnic injury.
Cardiac surgery with cardiopulmonary bypass (CPB) is associated with an increased risk of blood transfusions. The primary setup of the CPB circuit demands a priming volume of approximately 1600 mL of crystalloid solution which leads to a relevant hemodilution. The retrograde autologous priming (RAP) procedure minimizes hemodilution by displacing the crystalloid priming volume of arterial and venous lines via passive exsanguination of native blood prior to CPB initiation, resulting in higher hematocrits and reduction of red blood cell transfusion. RAP can also minimize the dilution of coagulation factors as well as red blood cells. Thus, the investigators hypothesized that RAP could maintain better coagulatory function after CPB. In this study, the investigators investigate the impact of RAP on the coagulation profile assessed by rotation thromboelastometry (ROTEM) in participants undergoing cardiac surgery.
During coronary artery bypass grafting (CABG) operations with cardiopulmonary bypass (CPB), the use of desflurane continuously or intermittently may have effects on serum brain natriuretic peptide (BNP) levels. The aim is to investigate the association between desflurane, serum BNP values, and clinical outcomes during CABG operations. In a prospective, randomized, double-blinded study, desflurane inhalational anesthesia was administered either continuously or intermittently (Group 1; n=60 versus Group 2; n=62). The preoperative and postoperative BNP levels at 24, 48 and 72 hours after surgery were collected. Outcomes were recorded.
Background: Endotracheal suction (ES), may cause changes like increase in blood pressure, heart rate (HR) and decrease in peripheral oxygen saturation (SpO2), which may cause changes in hemodynamic parameters (HPs) that increase the workload of the heart after surgery. Aim: The aim of this study is to determine the effect of the methods used in endotracheal tube (ET) fixation on HPs [systolic blood pressure (SBP), diastolic blood pressure (DBP), HR and SpO2] during ES. Study Design: The sample of this prospective, single-blind non-randomized clinical trial study included 86 intubated patients who were treated in the cardiovascular surgery intensive care unit (CVSICU) of a university hospital between September 2016 and December 2017. Methods: The ET fixations of the experimental group (n=43) were performed with tube holders while the ET fixations of the control group (n=43) were performed using plasters. The HPs of the patients were measured before, during, at the end of suction and 5 and 15 minutes after suction.
The investigators aimed to evaluate the association between the duration and stage of acute kidney injury (AKI) and the development of chronic kidney disease during postoperative three years in patients undergoing cardiac or thoracic aortic surgery.
