Observational StudyCerebral Oxygen Metabolism Before and After RBC Transfusion in Infants Following Major Surgical Procedures.
Although infants following major surgery frequently require RBC transfusions, there is still controversy concerning the best definition for requirement of transfusion in the individual patient. The aim of this study was to determine the impact of RBC transfusion on cerebral oxygen metabolism in noncardiac and cardiac postsurgical infants. ⋯ Following RBC transfusion, cerebral oxygen saturation increases and cerebral fractional tissue oxygen extraction decreases. The data suggest that cerebral oxygenation in postoperative infants with cerebral fractional tissue oxygen extraction greater than or equal to 0.4 may be at risk in instable hemodynamic or respiratory situations.

Furosemide Response Predicts Acute Kidney Injury After Cardiac Surgery in Infants and Neonates.
Cardiac surgery-induced acute kidney injury occurs frequently in neonates and infants and is associated with postoperative morbidity/mortality; early identification of cardiac surgery-induced acute kidney injury may be crucial to mitigate postoperative morbidity. We sought to determine if hourly or 6-hour cumulative urine output after furosemide in the first 24 hours after cardiopulmonary bypass could predict development of cardiac surgery-induced acute kidney injury and other deleterious outcomes. ⋯ Urine output response to furosemide within 24 hours of cardiopulmonary bypass predicts cardiac surgery-induced acute kidney injury development and other important morbidity in children younger than 90 days old; prospective validation is warranted.

Case ReportsPostoperative takotsubo cardiomyopathy: an illustration of the electrocardiographic features that raise suspicion for takotsubo.
Takotsubo cardiomyopathy is an increasingly recognized clinical disorder mimicking acute coronary syndrome. It is usually preceded by physical or emotional stress and recovery of the left ventricular systolic function occurs in most cases within 1-4 weeks. Takotsubo cardiomypathy can masquerade as ST-segment elevation myocardial infarction when chest pain, ST-segment elevation, and high cardiac biomarkers coexist. ⋯ Awareness of these electrocardiographic features has several diagnostic and therapeutic implications. Nevertheless, these electrocardiographic criteria alone cannot reliably differentiate between both entities, and the diagnosis of takotsubo cardiomyopathy is only established after coronary angiography confirms the absence of occlusive coronary artery disease and the characteristic apical ballooning is evident on left ventriculogram (in the case of the apical form). Herein, we present a case of postoperative takotsubo cardiomyopathy and discuss the various electrocardiographic features that raise suspicion for this transient cardiac syndrome.

Pulmonary Dead Space Fraction and Extubation Success in Children After Cardiac Surgery.
1) Determine the correlation between pulmonary dead space fraction and extubation success in postoperative pediatric cardiac patients; and 2) document the natural history of pulmonary dead space fractions, dynamic compliance, and airway resistance during the first 72 hours postoperatively in postoperative pediatric cardiac patients. ⋯ Initial postoperative dead space fraction correlates with the length of mechanical ventilation in two ventricle patients but not in single ventricle patients. Lower preextubation dead space fractions are a strong predictor of successful extubation in two ventricle patients after cardiac surgery, but may not be as useful in single ventricle patients.

Acute pain intensity has conventionally been assessed with a patient self-reported, unidimensional pain scale. This approach can inadvertently underestimate analgesia and result in large cumulative opioid doses and greater dose-dependent side effects and complications. ⋯ The TAG comprises the level of acceptable pain intensity, the level and types of desired activities, and accomplishing other patient-centered functional goals. The TAG evolves throughout the patient's hospitalization to promote timely discharge.
