There are currently few data available on the prognosis and outcome of recumbent horses.
To investigate the outcome of hospitalised horses that had been recumbent in the field or hospital and factors affecting their survival within the first 3 days of hospitalisation and survival after 3 days to hospital discharge.
Retrospective analysis of clinical records.
Records of 148 horses admitted to the William R. Pritchard Veterinary Medical Teaching Hospital, University of California Davis from January 1995 to December 2010 with a history of recumbency or horses that became recumbent while hospitalised were evaluated. Exact logistic regression was used to assess the association between clinical parameters and survival within the first 3 days of hospitalisation and survival to hospital discharge after 3 days.
There were 109 nonsurvivors and 39 survivors. Multivariate analysis showed variables associated with an increased odds of death within the first 3 days of hospitalisation included duration of clinical signs prior to presentation, with horses showing clinical signs for over 24 h having increased odds of death (P = 0.043, odds ratio [OR] 4.16, 95% confidence interval [95% CI] 1.04-16.59), the presence of band neutrophils (P = 0.02, OR 7.94, 95% CI 1.39-45.46), the horse not using the sling (P = 0.031, OR 4.22, 95% confidence interval 1.14-15.68) and horses that were unable to stand after treatment (P<0.0001, OR 231.15, 95% CI 22.82-2341.33). Increasing cost was associated with lower odds of death (P = 0.017, OR 0.96, for each additional $100 billed, 95% CI 0.93-0.99).
This study demonstrates that the duration of clinical signs, response to treatment and the ability of horses to use a sling are associated with survival to hospital discharge for recumbent horses.
目前关于卧地马的预后和转归的数据很少。
调查在野外或医院曾卧地的住院马匹的转归，以及影响其住院后3天内存活和3天后至出院存活的因素。
对临床记录进行回顾性分析。
评估了1995年1月至2010年12月间入住加利福尼亚大学戴维斯分校威廉·R·普里查德兽医教学医院、有卧地史或住院期间出现卧地情况的148匹马的记录。采用精确逻辑回归分析评估临床参数与住院后3天内存活以及3天后至出院存活之间的关联。
有109匹死亡马匹和39匹存活马匹。多变量分析显示，与住院后3天内死亡几率增加相关的变量包括就诊前临床症状持续时间，临床症状持续超过24小时的马匹死亡几率增加（P = 0.043，比值比[OR]4.16，95%置信区间[95%CI]1.04 - 16.59）、出现带状中性粒细胞（P = 0.02，OR 7.94，95%CI 1.39 - 45.46）、马匹未使用吊具（P = 0.031，OR 4.22，95%置信区间1.14 - 15.68）以及治疗后无法站立的马匹（P<0.0001，OR 231.15，95%CI 22.82 - 2341.33）。费用增加与死亡几率降低相关（P = 0.017，每增加100美元账单金额，OR 0.96，95%CI 0.93 - 0.99）。
本研究表明，临床症状持续时间、对治疗的反应以及马匹使用吊具的能力与卧地马出院存活相关。
