The objective of this study was to evaluate the relationship between the volume of fluid being produced at the time of thoracostomy drain removal and the time to hospital discharge in dogs and cats.
Records of 101 dogs and 26 cats with thoracostomy drains were reviewed. Three subgroups were created according to the reason for thoracostomy drain placement: P (postsurgical), A (air) and F (fluid). A generalised linear model with Poisson Errors was performed to test the relationship between the volume of fluid produced at the time of thoracostomy drain removal and the time to discharge. The volume of fluid produced and the time to discharge were compared between species and subgroups.
No significant relationship was found between the volume of fluid produced at the time of thoracostomy drain removal and the time to discharge in either species or between the time to discharge and the reason for thoracostomy drain placement. Animals with a volume of fluid higher than 2 ml/kg/day at the time of thoracostomy drain removal did not have increased hospitalisation times.
Thoracostomy drain can be removed, without clinical compromise, when the volume of fluid produced exceeds 2 ml/kg/day. However, other clinical parameters must be taken into consideration.
本研究的目的是评估犬猫胸腔闭式引流管拔除时产生的液体量与住院时间之间的关系。
回顾了101只犬和26只猫胸腔闭式引流管的记录。根据胸腔闭式引流管放置的原因创建了三个亚组：P（术后）、A（气胸）和F（积液）。采用泊松误差广义线性模型来检验胸腔闭式引流管拔除时产生的液体量与出院时间之间的关系。比较了不同物种和亚组之间产生的液体量和出院时间。
无论是在物种之间，还是在出院时间与胸腔闭式引流管放置原因之间，均未发现胸腔闭式引流管拔除时产生的液体量与出院时间之间存在显著关系。胸腔闭式引流管拔除时液体量高于2 ml/kg/天的动物住院时间并未延长。
当产生的液体量超过2 ml/kg/天时，可以在不影响临床状况的情况下拔除胸腔闭式引流管。然而，还必须考虑其他临床参数。
