About this trial

This is an interventional prevention trial for Congenital Heart Disease focused on measuring remote ischemic preconditioning, sevoflurane, total intravenous anesthetic

Eligibility Criteria

6 Months - 12 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Pediatric scheduled for cardiac surgery requiring the cardioplegic arrest and cardiopulmonary bypass

Exclusion Criteria:

  • Previous cardiac surgery
  • Urgent or emergent cases
  • Patient with the following diseases diabetes mellitus ,hypertension ,renal failure, hepatic and pulmonary diseases

Sites / Locations

  • Faculty of Medicine

Arm Description

Sevoflurane plus remote ischemic preconditioning anesthesia will be induced and maintain with sevoflurane in addition to remote ischemic preconditioning which will be done after induction and before cardiopulmonary bypass by inflating the cuff of blood pressure above 200mmhg in the lower limb every 5 min for 3 cycles

anesthesia will be induced and maintain with total intravenous anesthesia (propofol, midazolam plus fentanyl) during plus remote ischemic preconditioning in addition to remote ischemic preconditioning which will be done after induction and before cardiopulmonary bypass by inflating the cuff of blood pressure above 200mmhg in the lower limb every 5 min for 3 cycles

Outcomes

Primary Outcome Measures

Troponin I levels
The investigators will obtain blood samples for troponin I level pre-Cardiopulmonary bypass, 6, 12 and 24 hours after the surgery. Troponin I levels, as a marker of myocardial ischemia, have been used in previous adult and pediatric studies on preconditioning.

Secondary Outcome Measures

Highest inotropic score during the first 24 hours after cardiac surgery
Inotrope score is a useful predictor of morbidity and mortality in children who undergo heart surgery. The inotropic score is calculated as follows: 1 point is assigned for each mcg/kg/min of dopamine and dobutamine, and 10 points is assigned for each 0.1 mcg/kg/min of epinephrine, norepinephrine, and phenylephrine. Inotrope score is a useful predictor of morbidity and mortality in children who undergo heart surgery
Mortality at 30 days
Proportion of patients who dies within 30 days of their surgical repair
Cardiac function
Cardiac rhythm on return if it will be sinus rhythm or return with ventricular fibrillation

5. Study Description

Brief Summary
Remote ischemic preconditioning (RIPC) of the myocardium by limb ischemia/reperfusion may mitigate cardiac damage, but its interaction with the anesthetic regimen is unknown.
Detailed Description
The investigators will test if RIPC will be associated with differential effects depending on background anesthesia. Specifically, the investigators hypothesized that RIPC during sevoflurane anesthesia attenuates myocardial injury in patients undergoing congenital cardiac defects repair surgery and that effects may be different during propofol anesthesia.
