Comparison of the ability of esCCO and Volume View to measure trends in cardiac output in patients undergoing cardiac surgery.

Background: Cardiac output (CO) is a physiological variable that should be monitored during cardiac surgery. The purpose of this study was to assess the trending ability of two CO monitors, esCCO (Nihon Kohden™, Tokyo, Japan) and Volume View (VV) (Edwards Lifesciences, Irvine, USA).

Methods: A total of 19 patients were included in the study.

The mirroring technique: a navigation-based method for reconstructing a symmetrical orbit and cranial vault.

Background: The reconstruction of orbital structures and the cranial vault curvature can be challenging after trauma or wide resections for tumors. Sophisticated methods have been developed recently, but these are resource- and time-consuming.

Objective: We report the mirroring technique, which is an effective and costless application for navigation-guided reconstruction procedures.
