Impact of Priming the Infusion System on the Performance of Target-controlled Infusion of Remifentanil

November 22, 2011 updated by: Jong Yeop Kim, Ajou University School of Medicine

Study of Proper Operation of the Syringe Pump Used in Priming of the Syringe

The investigators attempted to determine an adequate priming volume for our infusion system, and investigated the extent of a possible delay of the drug effect, that would result from mechanical defects of the infusion system, with or without priming the infusion system, using direct gravimetrical measurements of virtual infusate amounts during target controlled infusion of 2 remifentanil diluents.

Detailed Description

Priming the infusion system (PRIMING) was performed using an evacuation of 2.0 ml to the atmosphere prior to Target-controlled Infusion (TCI). Forty eight TCI, using 50 μg/ml or 20 μg/ml of remifentanil diluents, were performed targeting 4.0 ng/ml of effect site concentration (Ceff), with or without PRIMING. Using simulations, the gravimetrical measurements of the delivered infusates reproduced actual predicted concentrations.

Outcome Measure
Measure Description
Time Frame
delivered infusates of remifentanil
Time Frame: base line from 30 min of TCI was maintained
For targetting an effect-site concentration (Ceff) of 4.0 ng/ml, were randomly performed using 50 μg/ml (Remi50) or 20 μg/ml (Remi20) of remifentanil, and with or without PRIMING, TCI data files, including predicted plasma (Cp-proper), and effect-site (Ceff-proper) concentrations were saved
base line from 30 min of TCI was maintained
