Design outcomes
Primary
| Measure | Time frame |
|---|---|
| First pass successful cannulation rate. Successful cannulation will be defined as free aspiration of blood and good arterial trace from arterial line. If artery is cannulated successfully in a single prick it will be defined as Successful first pass cannulationTimepoint: it will be assessed at the time of Radial artery cannulation (baseline) after induction of anaesthesia and before start of surgery. | — |
Secondary
| Measure | Time frame |
|---|---|
| Time taken for cannulation. It is defined as time elapsed from first skin prick to adequate arterial line trace.Timepoint: It will be assessed at the time of Radial artery cannulation (baseline) after induction of anaesthesia & before start of surgery. It will be assessed a single time;No. of skin puncturesTimepoint: It will be assessed at the time of Radial artery cannulation (baseline) after induction of anaesthesia & before start of surgery. It will be assessed a single time;Incidence of attempt failure. Attempt failure will be recorded if limb of insertion is changed. Timepoint: It will be assessed at the time of Radial artery cannulation (baseline) after induction of anaesthesia & before start of surgery. It will be assessed a single time;Incidence of Positional arterial . It is defined as arterial line whose trace gets distorted with slight change in wrist position.Timepoint: It will be assessed immediately at the after Radial artery fixation (baseline) after induction of anaesthesia & before start of surgery. It will be assessed a single time;Hematoma at the site of Radial arterial line.Timepoint: The site will be examined daily till postoperative day 5. It will be assessed six times at 24 hour intervals starting from postoperative day 0 at end of surgery to postoperative day 5;Ischaemic complicationsTimepoint: The site will be examined daily till postoperative day 5. It will be assessed six times at 24 hour intervals starting from postoperative day 0 at end of surgery to postoperative day 5 | — |
