From: Lidocaine spray 10% prior to intravenous catheterisation in dogs
Response to intra-venous catheterization after application of lidocaine spray 10% or NaCl 0.9% in 12 dogs. The response was scored with visual analogue scale (VAS) by three observers. The VAS score in mm is illustrated along the y-axis and along the x-axis each individual dog is illustrated. Each dog has six scores where black represents observer 1, red represents observer 2 and green grey represents observer 3. A circle represents the response after application of lidocaine 10% and a triangle represents the response after application of NaCl 0.9%
