Clinical TrialThe optimal insertion length of central venous catheter via the femoral route for open-heart surgery in infants and children.
The recommended insertion length of central venous (CV) catheter via the internal jugular or subclavian vein has been determined in infants and children. However, the insertion length via the femoral vein has not been well-studied. This study determined the optimal insertion length of CV catheter via the femoral vein. ⋯ It has been recommended to place the tip of the catheter below the level of renal veins to avoid blocking free flow of those veins. Therefore, we chose the mid-point, L3 level as the optimal tip position of the femoral venous catheter. The length derived from the above formula could be used as a guideline for CV catheter insertion via the femoral vein in infants and children.

Near-infrared spectroscopic cerebral oxygenation reading in neonates and infants is associated with central venous oxygen saturation.
The aim of the study was to elucidate easily determinable laboratory and vital parameters in clinical practice to explain variability of near-infrared spectroscopic cerebral oxygenation readings in critically ill newborns and infants using the NIRO 300 spectrometer. ⋯ Based on our study results cerebral tissue oxygenation readings by the NIRO 300 near-infrared spectrometer is influenced by central venous oxygen saturation, which partially explains intersubject variability of NIRS cerebral oxygenation readings.

Case ReportsNesiritide during extracorporeal membrane oxygenation.
Nesiritide is a recombinant formulation of B-type natriuretic peptide (BNP). Preliminary experience in the adult population has shown nesiritide to be an effective agent in the treatment of decompensated congestive heart failure (CHF) in adults. ⋯ In one patient, nesiritide in doses up to 0.09 microg.kg(-1).min(-1) were used to control mean arterial pressure while in the other patient, doses of 0.01-0.03 microg.kg(-1).min(-1) were used to augment urine output. The potential applications of nesiritide and dosing regimens for this agent in the ECMO population are discussed.

Case ReportsAutomatic atrial tachycardia in an infant following general anesthesia.
Automatic atrial tachycardia (AAT) is a rare supraventricular tachyarrhythmia (<10% of all supraventricular tachycardias), which can present in infants or young children. There are no published reports of AAT occurring in an infant or child following noncardiac surgery and general anesthesia. This report describes the management of a previously healthy 5-month-old infant, who developed AAT in the postanesthesia care unit following an uneventful circumcision under general anesthesia.
