Abstract

Objective

To describe the epidemiology of, and injuries associated with, low- versus higher-speed vehicular trauma and to identify risk factors associated with mortality.

Design

Retrospective study from January 2015 to November 2020.

Setting

University teaching hospital.

Animals

A total of 150 dogs with low-speed (<20 mph) vehicular rollover (LSVRO) trauma and 272 dogs with other vehicular trauma (hit by car [HBC]).

Interventions

None.

Measurements and Main Results

Eighty-five percent of vehicles causing LSVRO trauma were driven by owners or family members of the dogs. Dogs in the LSVRO group were older (median: 4 vs. 2 years, p = 0.001), smaller (median weight: 11 vs. 21.5 kg, p = 0.001), and more often female (53.3% vs. 40.1%, p = 0.005) than the HBC group. Pelvic fractures, sacroiliac luxation, prepubic tendon rupture, and vertebral fractures were more common in the LSVRO group, and more soft tissue surgical procedures were required than in the HBC group (18.0% vs. 8.85%, p = 0.02). Within the LSVRO group, abdominal injuries (e.g., abdominal hernia, prepubic tendon rupture), pelvic fractures, and traumatic brain injury were all associated with increased mortality. Surviving dogs had higher ionized calcium concentration (1.26 ± 0.1 mmol/L) than those that died (1.18 ± 0.1 mmol/L, p = 0.003). There was a 40% reduction in survival odds for every 1-point increase in animal trauma triage score (p < 0.001). Blood product requirement and each soft tissue surgery increased mortality by 98% (p < 0.001) and 74% (p = 0.001), respectively, while orthopedic surgery conferred a 25-fold increase in odds of survival (p < 0.001).

Conclusions

LSVRO trauma is characterized by a specific constellation of injuries compared with HBC trauma. Veterinary practitioners should be aware of the differences between the two trauma types and focus triage, resuscitation, and diagnostic tests in dogs with LSVRO trauma accordingly.

在兽医教学医院急诊服务的犬低速车辆侧翻创伤的特点。

目的：描述低速与高速车辆创伤的流行病学和相关损伤，并确定与死亡率相关的危险因素。设计：2015年1月至2020年11月的回顾性研究。单位：大学教学医院。动物：共150只低速犬（干预：无）。测量结果和主要结果：造成LSVRO创伤的车辆中，85%是由狗的主人或家庭成员驾驶的。LSVRO组的狗比HBC组更老（中位数：4岁对2岁，P = 0.001），更小（中位数体重：11对21.5 kg, P = 0.001），雌性狗更多（53.3%对40.1%,P = 0.005）。盆腔骨折、骶髂脱位、耻骨前肌腱断裂和椎体骨折在LSVRO组中更为常见，并且比HBC组需要更多的软组织手术（18.0%比8.85%,P = 0.02）。在LSVRO组中，腹部损伤（如腹疝、耻骨前肌腱断裂）、骨盆骨折和创伤性脑损伤均与死亡率增加有关。存活犬的离子钙浓度（1.26±0.1 mmol/L）高于死亡犬（1.18±0.1 mmol/L, P = 0.003）。动物创伤分诊评分每增加1分，生存几率降低40% (P)结论：与HBC创伤相比，LSVRO创伤具有特定的损伤特征。兽医从业者应该意识到两种创伤类型之间的差异，并相应地关注LSVRO创伤犬的分诊、复苏和诊断测试。

期刊介绍： The Journal of Veterinary Emergency and Critical Care’s primary aim is to advance the international clinical standard of care for emergency/critical care patients of all species. The journal’s content is relevant to specialist and non-specialist veterinarians practicing emergency/critical care medicine. The journal achieves it aims by publishing descriptions of unique presentation or management; retrospective and prospective evaluations of prognosis, novel diagnosis, or therapy; translational basic science studies with clinical relevance; in depth reviews of pertinent topics; topical news and letters; and regular themed issues. The journal is the official publication of the Veterinary Emergency and Critical Care Society, the American College of Veterinary Emergency and Critical Care, the European Veterinary Emergency and Critical Care Society, and the European College of Veterinary Emergency and Critical Care. It is a bimonthly publication with international impact and adheres to currently accepted ethical standards.
