Clinical Trial Summary

The study aimed to evaluate the combined effects of cyclosporine and remote ischemic preconditioning on MDA, calcium cytosol concentration, and mitochondrial edema in tetralogy Fallot patients undergoing corrective surgery.

Description:

Forty patients undergoing tetralogy Fallot corrective surgery were randomized to RIPC and cyclosporine (n=20) and control (n=20). Cyclosporin was administered 2 hour pre induction of anesthesia with the dose of 3 mg/kg body weight intravenously. RIPC was performed preoperatively after induction of anesthesia by inflating pressure cuff on the extremity 30 mmHg higher than systolic blood pressure of the patient for 5x5 minutes with 5 minutes reperfusion interval. Blood samples from coronary sinus and biopsies from the myocardial infundibulum were obtained three times at the condition of pre ischemic, ischemic, and reperfusion. MDA was measured from the blood samples, meanwhile calcium cytosol concentration and mitochondrial edema was measured from the biopsy samples.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Malondialdehyde (MDA)	ROS level is determined by measuring MDA concentration (nmol/mL)	1 year
Primary	Calcium cytosol concentration	Calcium concentration (nmol/mL) in cytosol is determined by ratiometric analysis on Fura Red- dyed heart cells.	1 year
Primary	Mitochondrial edema	Mitochondrial edema (%) is measured by decreasing of optical density that indicates change in mitochondrial matrix volume.	1 year
Secondary	Cardiac index	Examined with echocardiography, unit of measurement is litres per minute per square metre (L/min/m2).	1 year
Secondary	Troponin I	Measured from venous blood, unit of measurement is nanograms per milliliter (ng/mL).	1 year
Secondary	Creatine kinase- MB (CKMB)	Measured from venous blood, unit of measurement is units per liter (IU/L).	1 year
Secondary	Vasoactive inotropic score (VIS)	VIS was calculated as: dopamine dose (µg/kg/min) + dobutamine dose (µg/kg/min) + 100 × epinephrine dose (µg/kg/min) + 10 × milrinone dose (µg/kg/min) + 10 000 × vasopressin dose (unit/kg/min) + 100 × norepinephrine dose (µg/kg/min).	1 year
