Perioperative management of hemostasis in children and adolescents.

Invasive procedures in children are in most cases elective and are carried out in otherwise healthy children. While many surgeries are still performed in a hospital, more and more procedures are defined as "outpatient procedures," leading to increased discussion about safety and risks. This review will examine common practices, review the sparse literature and provide recommendations regarding the identification of children with increased bleeding risk, planning for children with known bleeding disorders and strategies for perioperative management.

Continuous non-invasive monitoring of tidal volumes by measurement of tidal impedance in neonatal piglets.

Background: Electrical Impedance measurements can be used to estimate the content of intra-thoracic air and thereby give information on pulmonary ventilation. Conventional Impedance measurements mainly indicate relative changes, but no information concerning air-volume is given. The study was performed to test whether a 3-point-calibration with known tidal volumes (VT) during conventional mechanical ventilation (CMV) allows subsequent calculation of VT from total Tidal-Impedance (tTI) measurements using Quadrant Impedance Measurement (QIM).
