To determine whether coagulation test results for blood samples obtained from heparinized jugular vein catheters in dogs are accurate.
Prospective, controlled study.
Fourteen clinically normal dogs.
Prothrombin time, activated partial thromboplastin time, concentration of fibrin degradation products, and fibrinogen concentration were measured in blood samples obtained by means of direct jugular venipuncture and through an indwelling jugular vein catheter 0, 2, 8, 24, and 48 hours after catheter placement. Blood samples were collected from the catheter by means of a 2-syringe technique, which involved discarding the first volume of blood collected.
For all sample times, mean values for samples obtained from the jugular vein catheter were not significantly different from mean values for samples obtained by means of venipuncture.
Blood samples for coagulation tests may be obtained from jugular vein catheters up to 48 hours after catheter placement in clinically normal dogs.
确定从犬肝素化颈静脉导管采集的血样凝血试验结果是否准确。
前瞻性对照研究。
14只临床正常的犬。
在颈静脉导管置入后0、2、8、24和48小时，通过直接颈静脉穿刺和经留置颈静脉导管采集血样，测定凝血酶原时间、活化部分凝血活酶时间、纤维蛋白降解产物浓度和纤维蛋白原浓度。采用双注射器技术从导管采集血样，即丢弃首次采集的血样量。
在所有采样时间，从颈静脉导管采集的样本均值与通过静脉穿刺采集的样本均值无显著差异。
在临床正常的犬中，颈静脉导管置入后长达48小时的血样可用于凝血试验。
