Study Details

Study Description

Brief Summary

The main purpose of this study is to compare myocardial injury of patients undergoing congenital cardiac defects repair surgery (RACHS Risk Score one, two or three) under total intravenous anesthesia compared to inhalation anesthesia with sevoflurane. The primary aim of the study is to evaluate the troponin I levels in patients following congenital heart surgery and elucidate if one of the two anesthetic techniques (TIVA x inhalation anesthesia) is more effective in reducing troponin I levels in the first 72h after surgery..

Sixty six are planned to be included in the study and the follow-up will take approximately 3 days for the primary outcome.

As a secondary outcome evaluate the BNP, CPK and CKMB postoperative levels in the same period (72h), also ICU and hospital lengh of stay (LOS), duration of mechanical ventilation, inotropic/vasoactive drugs use and incidence of renal injury (according to pediatric RIFLE score).

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Sevoflurane

Anesthetic induction with sevoflurane by mask 3-8% and fresh gas flow 2-8 l/min (FiO2 50-100%) followed by ketamine 1-2 mg/kg, midazolam 0,1-0,5 mg/kg, fentanyl 2-4 mcg/kg and pancuronium 0,1 mg/kg. After orotracheal intubation, anesthesia is maintained with fentanyl 10 - 30 mcg/kg according to clinical needs and sevoflurane 1-3% (end-tidal concentration) before and after cardiopulmonary bypass. Specifically during cardiopulmonary bypass extra fentanyl 1-5 mcg/kg and pancuronium 0,1 mg/kg will be administered and the sevoflurane sustained 1-3% in a specific sevoflurane vaporizer included in the CPB machine. Pressure-controlled ventilation will be applied to both groups objectifying normocarbia and normoxia. Ringer's lactate (RL) will be used as crystalloid solution for fluid therapy.

Drug: Sevoflurane
Use of sevoflurane (compared to total intravenous anesthesia) in congenital heart deffects surgeries.

Other: Intravenous anesthetics (TIVA)

Anesthetic induction with ketamine 1-3 mg/kg, midazolam 0,1-0,5 mg/kg, fentanyl 2-4 mcg/kg and pancuronium 0,1 mg/kg after preoxygenation with FiO2 between 50-100% and fresh gas flow 4-8 l/min. After orotracheal intubation, anesthesia is maintained with fentanyl 10 - 30 mcg/kg according to clinical needs and continuous infusion of midazolam and ketamine 0,2-0,8 mg/kg/h and 1-2 mg/kg/h respectively before and after cardiopulmonary bypass. Specifically during cardiopulmonary bypass extra fentanyl 1-5 mcg/kg, midazolam 0,1-0,5 mg/kg and pancuronium 0,1 mg/kg will be administered. Pressure-controlled ventilation will be applied to both groups objectifying normocarbia and normoxia. Ringer's lactate (RL) will be used as crystalloid solution for fluid therapy.

Drug: TIVA
Total intravenous anesthesia
