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 by three observers and normalised within each observer. The mean score within each dog was calculated and is illustrated along the y-axis. Along the x-axis each individual dog is illustrated. The response after lidocaine is illustrated by a black circle and for NaCl as a red square, whenever filled, indicates the first treatment
