Acute Kidney Injury and Renal Regional Oxygen Saturation During Aortic Arch Reconstruction in Infants.
Acute kidney injury is a serious postoperative complication following cardiac surgery. The aortic arch repair technique using antegrade selective cerebral perfusion has been used, but it is unclear whether subdiaphragmatic organs such as the kidneys are perfused adequately. The authors compared intraoperative renal regional oxygen saturation using near-infrared spectroscopy between infants with and without postoperative acute kidney injury after undergoing aortic arch reconstruction. ⋯ The intraoperative renal tissue oxygen saturation was not different between the groups with or without postoperative acute kidney injury in infants who underwent aortic arch repair using antegrade selective cerebral perfusion.

Computerized Tomographic Anatomic Relationships of the Thoracic Paravertebral Space.
A wide range of insertion points lateral to the midline are recommended for paravertebral blockade. The authors hypothesized that in a given subject, using an insertion point at the tip of the transverse process has a superficial but consistent depth to the pleura. The authors also hypothesized that for a given insertion point, depths to the pleura are related directly to the patient's anthropomorphic indices. ⋯ The authors concluded that an insertion point at the tip of the transverse process may provide effective and safer paravertebral blockade and that depth to the pleura cannot be predicted reliably by patients' morphometric profiles.

Effects of Isoflurane Anesthesia on Aortic Compliance and Systemic Hemodynamics in Compliant and Noncompliant Aortas.
To investigate the effect of general anesthesia on aortic compliance and other cardiovascular hemodynamics in chronically instrumented pigs with compliant and noncompliant (stiff) aortas. ⋯ Induction of general anesthesia caused a similar increase in total arterial compliance and was associated with a decrease in SBP that was more pronounced in animals with noncompliant aortas. These results indicated that anesthesia caused a greater hemodynamic effect on noncompliant (stiff) aortas and may explain the extensive hemodynamic fluctuation and instability often observed in atherosclerotic, elderly patients with stiff aortas.
