Compare the effect of periradial injection of papaverine versus nitroglycerine on radial artery diamter before cannulation of it in cardiac surgery.
we want in this study to facilitate radial artery canulation and decrease the number of attemps of puncture which may lead to disappearance of the pulse. The aim of this study is to compare the effect of adding papaverine to local anesthetic xylocaine versus adding nitroglycerine to it on the diameter and palpability of radial artery and if perioperative spasm will decrease significantly with one of these methods.

diameter of radial artery
after periradial injection of one of the drugs we will feel the radial artery pulse and record if there is a change in the palpatory score and mesure the diameter of the radial artery by ultrasound in cardiac surgery patients
Time frame: 20 minutes
spasm of radial artery
detect if there is postoperative spasm of radial artery
Time frame: 24 hours
