The model was applied successfully to predict PICC for different residual plastic fields which provided an additional validation of Δyp as the parameter controlling PICC.
An analytical model was used to isolate the effect of residual plastic deformation on PICC, however significant differences were obtained relatively to finite element results.
Kaplan-Meier curves for CVC and PICC showed statistical difference for obstruction (p<0.001) in PICCs.
In vitro, no static or dynamic pressure differences were found between the PICC and a conventional CVP catheter.
Statistical analysis was performed using a Bland-Altman plot to determine the average bias, standard error, and difference range between measurements obtained via PICC and control catheters.
Their international character qualifies the PICC for the Restatement (2d) Conflict of laws.
The average bias determined by Bland-Altman plot was 0.043 mmHg for 5 Fr PICC and 0.023 mmHg for 6 Fr PICC with a difference range of 1.0 to -1.0.
The sample size was not enough to gain a powerful conclusion since PICC was started late in the hospital, also the immunity differences of the included infants may lead to bias.
PICCs are placed by trained nurses who constitute a PICC team.
Our results confirm our hypothesis that there is no difference between static and dynamic pressures when measured in vitro with a PICC as compared to a conventional triple lumen CVP catheter.
