Isn't diluting with blood going to buffer the pH of Papaverine ?

All cases with dissection of lima  during intraluminal injection were those with previous trauma to lima during the harvest.Also before cross clamping I transect the distal lima and let it bleed for 1 minute into a bowl .If more than 100 cc then Ok,50-100 reobserve before anastomosis  of the vessel,<50 cc put lima to a diagonal.I use the blood in the bowl for vein dilatation.
