IRCT20190922044844N1 IRCT 2020-03-03 Esfahan University of Medical Sciences Comparison of effect of two different frequencies of Intra-aortic balloon pump on hemodynamic situation in patients after Coronary Artery Bypass Graft IABP Comparison of effect of 1:1 and 1:2 frequency of Intra-aortic balloon pump on hemodynamic situation in patients with medium dose of inotrope after Coronary Artery Bypass Graft 2019-10-07 anticipated 9 Complete https://irct.ir/trial/42382 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Single, Purpose: Treatment. N/A Influence of 1: 1 and 1: 2 frequency balloon pumps. This design is a quasi-experimental study of pre-test - posttest that compares all those who were at the 1: 1 frequency before and at the start of the intervention with the 1: 2 frequency step.. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is Due to secondary data analysis

Isfahan Iran (Islamic Republic of) 1611812345 +98 31 3773 3390 am_sadeghi@med.mui.ac.ir Esfahan University of Medical Sciences Iran (Islamic Republic of) People who underwent CABG but due to low cardiac output, mean arterial blood pressure less than 80 mmHg failed to separate from the cardiopulmonary pump device and required postoperative IABP. Patients who are consenting to participate in the project, which will be obtained from the legal guardian if the patient is unconscious. no limit no limit Both People who perform CABG at the same time as aortic valve and arch operations such as: aortic valve replacement, Bental surgery, etc. Treatment - Devices This design is a quasi-experimental study of pre-test - posttest that compares all those who were at the 1: 1 frequency before and at the start of the intervention with the 1: 2 frequency step. The rate of change in the velocity time integral of aortic blood flow during systole. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: The velocity time integral value of aortic blood flow during systole is measured by echocardiography. The measurement of area left ventricular outflow tract ( area LVOT). Timepoint: At moderate doses of inotropic drugs, this variable is measured before the intervention begins. Method of measurement: This variable is measured by echocardiography,. Rate of change in systolic blood pressure in patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: it's measured by a built-in arterial line for patients and cardiac monitoring devise. Rate of change in diastolic blood pressure in patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: it's measured by a built-in arterial line for patients and cardiac monitoring devise. Rate of change in heart rates in patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: it's measured by a cardiac monitoring devise. Rate of change in mean arterial blood pressure in patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: it's measured by a built-in arterial line for patients and cardiac monitoring devise. The measure of body surface area. Timepoint: At moderate doses of inotropic drugs, this variable is measured before the intervention begins. Method of measurement: This variable is measured by echocardiography,. Rate of change in cardiac output of patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: It will be calculated by the formula and collected required data. Rate of change in cardiac index of patients. Timepoint: In average dose of Inotropes, this parameter is measured at 1:1 frequency,then the frequency is switched to 1:2 and after 20 minutes, it's measured at 1:2 frequency again. Method of measurement: It will be calculated by the formula(cardiac output divided by body surface area) and collected required data.
