Design outcomes

Primary

MeasureTime frame
Numerical Rating Scale (NRS) pain score during radial artery catheterisation.Timepoint: After the completion of radial artery catheterization.—

Secondary

MeasureTime frame
1. NRS pain score during LCNF block or lidocaine infiltration (timepoint: After completion of nerve block/local anaesthesia infiltration (during assessment of successful blockage/infiltration)). 2. First attempt success rate (timepoint: After the completion of radial artery catheterization ) 3. Post procedure analgesia (After the completion of radial artery catheterization and during post-procedure observation. ) 4. Radial artery patency(After 24 hours post-procedure) Timepoint: AS MENTIONED IN EACH ACTEGORY—
