Measuring Cerebral Carbon Dioxide Reactivity With Transcranial Doppler and Near-Infrared Spectroscopy in Children With Ventricular Septal Defect.
Neurologic impairment is frequently observed in children with congenital heart disease. Impairment in cerebrovascular carbon dioxide reactivity (CO2R) is related with poor neurologic outcomes. The present study examined CO2R measured with transcranial Doppler (TCD) and near-infrared spectroscopy (NIRS) in children with ventricular septal defect undergoing cardiac surgery. ⋯ During anesthesia, CO2R remains preserved in children with a ventricular septal defect. Even though there is lack of correlation between CO2R-TCD and CO2R-NIRS, changes in TOI and VMCA were correlated as the PETCO2 changed. NIRS may be used as a surrogate to investigate CO2R when the ultrasound window is poor.

ReviewAnesthesia in Pediatric Patients With Congenital Heart Disease Undergoing Noncardiac Surgery: Defining the Risk.
The incidence of moderate to severe congenital heart disease (CHD) in the United States is estimated to be 6 per 1,000 live-born, full-term infants. Recent advances in pediatric cardiology, surgery, and critical care have improved significantly the survival rates of patients with CHD leading to an increase in prevalence in both children and adults. ⋯ They often are faced with the question, "Is this patient too high risk for anesthesia?" The objective of this literature review is to provide a greater understanding of patients at high risk and to quantify the risk for patients, their families, and clinicians. In addition, specific high-risk lesions (single ventricle, Williams-Beuren syndrome, pulmonary hypertension, cardiomyopathies, and ventricular assist devices) are described.

Oxygen Reserve Index Predicts Hypoxemia During One-Lung Ventilation: An Observational Diagnostic Study.
To determine the accuracy of the Oxygen Reserve Index (ORi) to predict hypoxemia during one-lung ventilation (OLV). ⋯ An ORi value equal to zero, 5 minutes after the onset of mechanical ventilation in the supine position, predicts the development of hypoxemia during OLV. These findings may be helpful to adjust FIO2 individually in patients undergoing OLV and to avoid unnecessary high concentrations of oxygen.
