- Abstract
Objective: To assess the relationship between shock index (SI) and mortality in dogs with head trauma (HT). A secondary objective was to compare SI with the animal trauma triage (ATT) score and Modified Glasgow Coma Scale (MCGS) score in HT cases. A tertiary aim was to assess if SI is predictive of survival to discharge or improvement in presenting neurologic signs. Design: Retrospective study from January 2015 to December 2020. Setting: Tertiary referral level II veterinary trauma center. Animals: Eighty‐six dogs with evidence of HT presenting through emergency for various traumas compared to 60 healthy control dogs. Measurements and Main Results: SI was calculated using the quotient of heart rate over systolic blood pressure measured on presentation. SI was significantly higher in HT patients than healthy controls (P = 0.0019). SI was not significantly different between traumatic brain injury dogs that died or were euthanized and HT dogs that lived until the time of discharge (P = 0.98). SI was not significantly different between HT dogs that were neurologically normal at the time of discharge and HT dogs that were static or improved but not normal neurologically at the time of discharge (P = 0.84). In HT dogs, SI did not correlate with ATT score (P = 0.16) or MGCS score (P = 0.75). There was no significant difference in SI and length of hospitalization until death or discharge (P = 0.78). Conclusions: SI was significantly higher in HT patients compared to control patients. Interestingly, SI was not correlated with ATT score or MGCS score. The use of SI in HT patients warrants further investigation to assess the efficacy in predicting mortality.
