Background
The radial approach is standard of care for coronary angiogram as it confers a lower incidence of major vascular access related complications and allows for early mobilization.
This study aims to evaluate the effectiveness of eutectic mixture of local anesthesia (EMLA) cream in reducing pain as part of an initiative to improve patient experience after radial puncture.

Methods
218 patients booked for elective coronary angiogram were recruited. EMLA cream was applied prior to radial artery puncture. All patients were given subcutaneous lignocaine at the puncture site. We evaluated the mean pain score amongst the whole population.
Within this population, 71 of them had previous coronary angiograms performed without EMLA application. We compared the degree of radial pain with and without EMLA application in this group of patients.
Radial pain was measured by the numeric pain rating scale (NPRS).

Radial pain was measured by the numeric pain rating scale (NPRS).
Results
The mean pain score of the whole study population was 2.48. Majority of patients (83.1%) felt that application of EMLA cream was necessary to improve their experience.
Analysis of patients who had no EMLA application for previous coronary angiogram showed that radial pain was significantly lower with EMLA application. (NPRS: 4.41 vs 2.57, p= <0.01). Age, gender and the indication of elective coronary angiogram did not significantly affect the reduction in pain score.
The mean duration of EMLA application prior to radial puncture was 53.1 minutes. The duration was not significantly associated with reduction of radial pain.

Conclusion
Application of the EMLA cream is easy and effective in reducing pain in patients undergoing coronary angiogram via radial approach. This appears to be well received amongst the patients. The reduction in radial pain may help to reduce the sympathetic drive of these patients and possibly reduce incidence of radial artery spasm which can represent a significant challenge to access and reduce procedural success rate.
