摘要

本研究的目的是探讨经耳静脉置入仔猪颈外静脉的可行性。纳入46头七氟咪达唑仑麻醉仔猪。采用Seldinger技术经耳静脉置管颈外静脉。第一部分(n = 27):最佳穿刺位置以三角结节为标志到达颈外静脉。通过计算机断层扫描在25头仔猪中验证了导管的最终位置。记录置管时间,通过反复采血评估导管通畅程度,持续4小时。第2部分(n = 19):耳静脉置管不考虑任何标志。如第1部分所述,对血液采样的功能进行了评估。在第1部分和第2部分中,分别有25/27和18/19头仔猪可以将导管推进。成功置管所需时间中位数(范围)为1.95 (1-10)min (n = 38)。三角结节是到达颈外静脉的良好标志。但也可以通过导管进行血液取样,导管的末端略高于颅部,直至颈外静脉。尽管导管进展顺利,但不可能在研究的每一部分(总共2头仔猪)都从一根导管中采集血液。其中一根导管出现管腔损伤,而另一根在从动物身上取出后表现正常。综上所述,93.5%的仔猪可以通过耳静脉中心静脉置管,89.1%的仔猪(n = 46)可以重复采血。

Non-surgical external jugular vein catheterization using an ear vein access in piglets.

The objective of this study was to investigate the feasibility of external jugular vein catheterization through an ear vein in piglets. Forty-six sevoflurane-midazolam anaesthetized piglets were included. External jugular vein catheterization was conducted through the ear vein using the Seldinger technique. Part 1 (n = 27): optimal puncture site was based on the deltoid tuberosity as a landmark to reach the external jugular vein. The final position of the catheter was verified in 25 piglets using computer tomography. Catheterization time was recorded and patency of the catheter assessed by repeated blood sampling for up to 4 h. Part 2 (n = 19): ear vein catheterization was without taking into account any landmarks. Functionality for blood sampling was evaluated as described in part 1. Catheter advancement was possible in 25/27 and 18/19 piglets in parts 1 and 2, respectively. Median (range) time required for successful catheterization was 1.95 (1-10) min (n = 38). The deltoid tuberosity was a good landmark to reach the external jugular vein. But blood sampling was also possible through catheters ending slightly cranial to the external jugular vein. Despite successful catheter advancement, blood sampling was not possible from one catheter in each part of the study (total: two piglets). One of these catheters presented luminal damage, while the other one presented as normal after being removed from the animal. Summarizing, central vein catheterization through the ear vein was feasible in 93.5% and repeated blood sampling was possible in 89.1% of the piglets (n = 46).
