Table 3 Summary results of Viscoelastic Coagulation Monitor Vet (VCM Vet) tracings (n = 160) from 20 dogs undergoing anaesthesia and elective orthopaedic surgery over the four study stages presented as BL = baseline, PM = 15 min following premedication, A = 60 min after inhalant initiation, R = 60 min after inhalant termination, showing the number (%) of tracings with decreased, normal, or increased clot formation rate, clot strength, and clot lysis rate and overall interpretation of number (%) of tracings that were hypocoagulable, normocoaguble, hypercoagulable, or hyperfibrinolytic. All tracings evaluated following a rubric (Additional file 1: Appendix A) by single blinded investigator
