Anesthesia and the Developing Brain: a Comparison of Two Anesthetic Techniques
Study Overview

Intervention / Treatment
Detailed Description
All subjects will be consented prior to participation in this study and prior to randomization.
All the subjects enrolled in the study will receive a preoperative assessment by one of the cardiac anesthesiologists and receive standardized induction with sevoflurane up to 2%, 2 mcg/kg of fentanyl and 1 mg/kg of rocuronium. The anesthetic maintenance will be determined using a computer- generated randomization table and assigning each patient to one of the two anesthetic regimens. Both of these anesthetic techniques are standard of care and are commonly used for these procedures.
Anesthetic Technique:
Volatile anesthetic:
In volatile anesthetic technique, maintenance of anesthesia will be standardized to the volatile anesthetic isoflurane. Isoflurane will be used for the study since this is what is presently available on the CPB machines. Anesthesia at 1.0 minimum anesthetic concentration (MAC) indicates that at this concentration 50% of the patients will not move when surgically stimulated. Anesthesiologists commonly use about 1.2-1.4 MAC in neonates, since the MAC value in infants is higher than that of children and adults. Isoflurane will be delivered at 1.5-2.0%% as required for anesthetic management.
Rocuronium or pancuronium will be used for muscle relaxation. Narcotic, fentanyl will be administered at no greater than 2 mcg/kg/hr.
Narcotic-based anesthetic:
In narcotic based anesthetic technique, no volatile anesthetics will be used except during induction.
Maintenance of anesthesia will be with fentanyl 5 mcg/kg/hr not to exceed 10 mcg/kg/hr.
The anesthetic may be supplemented with dexmedetomidine 0.05 mcg/kg/hr but not to exceed 1.0 mcg/kg/hr. Narcotic-based anesthetic will be used by the cardiac anesthesia team and the CPB technician throughout the operative case. 5 mcg/kg/hr of fentanyl is felt to represent 0.6 MAC of anesthesia.
Postoperative Sedative and Analgesic Care:
As per institutional standard of care, postoperative sedation will consist of fentanyl infusions of 2-4 mcg/kg/hr for the first 48 hours postoperatively.
A total of 9 Blood samples will be collected at different time points throughout the entire study for metabolomics determination (NAA/Cr and Chol/Cr)
EEG monitoring will be done for baseline in the pre-operative period for 15-20 minutes, during surgery and post-operatively up to 48 hours and prior to discharge for 15-20 minutes. Neurological and behavioral testing including Bayley Exam III will be done at 18-48 months.

ACTIVE_COMPARATOR: Volatile Anesthesia
In volatile anesthetic technique, maintenance of anesthesia will be standardized to the anesthesia will be standardized to the volatile anesthetic isoflurane. Rocuronium or pancuronium will be used for muscle relaxation. Additionally, narcotic fentanyl will be administered at no greater than 2 mcg/kg/hr (low dose). However, the primary anesthetic during CPB will be isoflurane with no narcotic administered during CPB. |
Isoflurane (volatile anesthesia) will be delivered at 1.5-2.0%%
as required for anesthetic management.
Fentanyl (narcotic anesthesia) maintenance will be with fentanyl 2 mcg/kg/hr.
|
ACTIVE_COMPARATOR: Narcotic based anesthesia
In narcotic based anesthetic technique, no volatile anesthetics will be used past induction. Maintenance of anesthesia will be with fentanyl 5 mcg/kg/hr not to exceed 10 mcg/kg/hr (high dose). |
Fentanyl (narcotic anesthesia) maintenance will be with fentanyl 5 mcg/kg/hr not to exceed 10 mcg/kg/hr.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Bayley III
Time Frame: Assessed once between age 18 to 48 months (approximately 2 hours to assess), up to 48 months from study start
|
Neurodevelopmental assessment scores are age dependent and based motor and behavioral abilities, often reported for normal or abnormal for age.
Bayley Scales of Infant and Toddler Development, third edition, (Bayley III) is an instrument designed to measure the developmental functioning of infants and toddlers between the ages of 1 month and 42 months (age adjustments for prematurity are accommodated with the tool).
It provides age specific composite scores for cognitive (91 items, score min 55 max 145), language (98 items, score min 47 max 153), and motor (138 items, score min 46 max 154) skills.
For all scales, higher scores are better and lower scores indicate possible delay/deficit.
|
Assessed once between age 18 to 48 months (approximately 2 hours to assess), up to 48 months from study start
|
Electroencephalogram
Time Frame: EEG taken immediately prior to surgery, during surgery, during cardiovascular intensive care unit (CVICU) stay (up to 48 hours after surgery), and immediately prior to discharge (between 5 to 20 minutes to assess EEG at each time point)
|
Brain electrical activity: observation is for brain region specific abnormal or seizure activity.
Number of participants with abnormal EEG are reported.
