Three years experience with a patient data management system at a neonatal intensive care unit.
We report about our experience with the patient data management system (PDMS) Hewlett Packard CareVue 9000 at two neonatal ICUs. We describe our PDMS configuration (hard- and software), local adjustments and enhancements such as knowledge based systems for calculating the parenteral nutrition of newborn infants (VIE-PNN), for advising medication (VIE-Nmed), and for managing mechanical ventilation (VIE-VENT), and the results of a structured interview with our staff members about the acceptance of the system. Despite some criticism nearly all collaborators liked the system, especially because of its time saving automated documentation of vital data and mechanical ventilation parameters. ⋯ Main points of critique were the system's therapy planning facilities (medication administration records), the restrictive facilities for documenting patient care and the yet unsolved problems of data evaluation and export. PDM systems have to be constantly adapted to the user's needs and to the changing clinical environment. Living with the system asks for an intensive dialog with the system and its functionalities, for creativity and well defined ideas about the future system development.

A formula to calculate oxygen uptake during low flow anesthesia based on FIO2 measurement.
Monitoring of oxygen uptake during general anesthesia would have several benefits, but unfortunately, this is usually not available in the clinical routine situation. The herein proposed formula to calculate oxygen uptake (. VO2) necessitates only the accurate measurement of FIO2 as well as fresh gas flow and composition. ⋯ In order to obtain representative results, calculation of. VO2 should be performed only after achievement of respiratory steady state conditions. Due to its simplicity and wide availability, it has the potential to become a valuable extension in anesthesia monitoring during the performance of routine general anesthesia.

Comparative StudyTranscranial Doppler blood flow velocity versus 133Xe clearance cerebral blood flow during mild hypothermic cardiopulmonary bypass.
Transcranial doppler (TCD) is used during cardiopulmonary bypass (CPB) to assess cerebral emboli and to estimate cerebral perfusion. We sought to compare TCD middle cerebral artery blood flow velocity (Vmca) to 133Xe clearance cerebral blood flow (CBF) measurements during mild hypothermic CPB thus determining its utility in cerebral perfusion assessment. ⋯ These findings suggest that TCD Vmca is a relatively poor correlate of CBF during mild hypothermic CPB.
