Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Secondary endpoints will be total time for completion of the procedure, for the digital palpation group this is the time from first palpation of the artery till placement of the catheter. In the US groups, this is the time from first contact of the US transducer with the subject*s skin until placement of the catheter. Other recorded parameters will be total attempts needed to complete the procedure, total attempts per group, skin punctures, failures | — |
Primary
| Measure | Time frame |
|---|---|
| The main study endpoint will be the rate of successful first attempt for catheterization. An attempt is defined as a straight advancement of the needle until positioned in the artery. If the needle is withdrawn 5 mm or more and advanced again, this counts as a new attempt. | — |
