Objective To compare the analgesic effect of intra-articular (IA) and intravenous (IV) morphine in horses with experimentally induced synovitis.Animals Eight adult horses.Study design Randomized, observer blinded, double dummy trial with sequential crossover design.Methods Radiocarpal synovitis was induced by IA injection of lipopolysaccharide on two occasions separated by a 3-week washout period. In one study period horses received treatment IA; morphine IA (0.05 mg kg(-1)) plus saline IV and in the other study period they received treatment IV; saline IA plus morphine IV ( 0.05 mg kg) 1). Lameness and pain were evaluated repeatedly by two observers throughout each of the two 168-hour study periods. Pain was evaluated by use of a visual analogue scale of pain intensity ( VAS) and a composite measure pain scale ( CMPS). Comparison of treatments was performed by analysis of variance with repeated measurements. Significance level was set to p
