ReviewClinical utility of B-type natriuretic peptide (NP) in pediatric cardiac surgery - a systematic review.
NP is a biomarker that has been used in the diagnosis, management, and prognostication of a number of cardiovascular disorders in the pediatric population. The physiological role of this hormone is to allow the myocardium to adapt to stress or strain imposed by a volume and/or pressure load. ⋯ NPs provide a simple, noninvasive and complementary tool to echocardiography that can be used to assist clinicians in the assessment and management of pediatric patients with congenital heart disease in the perioperative period.

Observational StudyPressure recording analytical method and bioreactance for stroke volume index monitoring during pediatric cardiac surgery.
It is currently uncertain which hemodynamic monitoring device reliably measures stroke volume and tracks cardiac output changes in pediatric cardiac surgery patients. ⋯ Pressure recording analytical method and bioreactance provided similar SVI estimation at stable hemodynamic conditions, while bioreactance SVI values appeared significantly lower than PRAM at the end of CPB and after fluid replacement.

Continuous noninvasive cardiac output in children: is this the next generation of operating room monitors? Initial experience in 402 pediatric patients.
Electrical Cardiometry(™) (EC) estimates cardiac parameters by measuring changes in thoracic electrical bioimpedance during the cardiac cycle. The ICON(®), using four electrocardiogram electrodes (EKG), estimates the maximum rate of change of impedance to peak aortic blood acceleration (based on the premise that red blood cells change from random orientation during diastole (high impedance) to an aligned state during systole (low impedance)). ⋯ Electrical cardiometry provides real-time cardiovascular information regarding developing hemodynamic events and successfully tracked the rapid response to interventions in children of all sizes. Intervention decisions must be based on the combined data from all monitors and the clinical situation. Our experience suggests that this type of monitor may be an important addition to real-time hemodynamic monitoring.

Comparative StudyNoninvasive cardiac output monitoring using bioreactance-based technique in pediatric patients with or without ventricular septal defect during anesthesia: in comparison with echocardiography.
We evaluated the use of bioreactance-based noninvasive cardiac output (CO) monitoring technique (NICOM(™), CO(NICOM)) in pediatric patients with or without ventricular septal defect (VSD) during anesthesia induction to determine its agreement with the measurements assessed by echocardiography (echo, CO(ECHO)). ⋯ In children without heart defects, the CO measured by NICOM shows a good agreement with the echo during anesthesia induction. The NICOM technique underestimates echo although a strong correlation exists between two methods in children with ventricular septal defect.

Observational StudyLumbar punctures in thrombocytopenic children with cancer.
Lumbar punctures (LP) in patients presenting thrombocytopenia are linked to the possibility of bleeding and spinal hematomas. The minimum platelet count required for the safe performance of spinal procedures is still under discussion. Children with some oncology diseases require routinely lumbar punctures; such patients often present thrombocytopenia, making this group an ideal population to study the association between lumbar puncture in thrombocytopenic patients and complications. ⋯ Even in thrombocytopenic patient, an epidural hematoma would be a relatively rare complication following lumbar puncture. Despite the large number of punctures performed on patients with platelet counts below 100,000 mm(-3) (n = 1108), further studies are necessary in order to determine a lower safe platelet count threshold for the performance of lumbar punctures in healthy patients undergoing neuraxial anesthesia.
