title: Catheterization of the auricular vein in cattle: 68 cases (1991-1994).
abstract: OBJECTIVE
  To evaluate the use of auricular vein catheters (AVC) in cattle in a clinical setting.
  
  
  METHODS
  Case series.
  
  
  METHODS
  57 cattle.
  
  
  METHODS
  68 AVC were placed in cattle for the administration of drugs or rehydration fluids. Catheter size, quantity of fluids administered, duration of administration, drugs administered, duration of catheter maintenance, and problems were recorded.
  
  
  RESULTS
  The AVC ranged in size from 20 to 14 gauge, with the latter being the predominate size. A maximum flow rate of 7.7 L/h was achieved, and the flow rate was satisfactory in all but 1 case. The maximum duration of maintenance was > 96 hours. Problems occurred in 29 of 68 (43%) catheterizations; the most frequent problem was occlusion of the catheter, which occurred 16 times (24%). No serious complications occurred.
  
  
  CONCLUSIONS
  Auricular vein catheters were a convenient, safe, and low-cost alternative to jugular vein catheters.
