Summary: | 碩士 === 國立臺灣大學 === 獸醫學系 === 82 === This study is divided into two experimental groups. In group A,
side by side, double-lumen, Polyurethane catheters were
applied to five dogs with either sexes(3 male and 2 female)
weighing 11.5 -23 kg in the periods of 7 to 21 days external
jugular vein as the vascular access of hemodialysis.
Vascular thrombosis was prevented by 1.3 ml of heparin (5,000
IU/ml)flushing and by oral aspirin 10 mg/kg B.W. Once daily.
Hemodialysis was the removal of catheters. Complications
are described as following: severe hemorrhage at the puncture
site in one case, local inflammation at the catheter entry site
in 5 cases, catheter withdrawn by the dog in 2 cases, severe
hematoma in 2 cases, and inadequate blood flow in 3 cases.
Venous stenosis was observed in 4 cases on autopsy. In group
B, unreserved teflon single lumen catheters were placed
bilaterally to 6 dogs of either sex ( 3 male and 3 female)
weighing 12-22kg, which were removed after each hemodia- lysis.
In 19 cases, vein stenosis developed in 5 catheterization ,
hematoma was noted in 2 cases, and the catheter was withdrawn
by one dog. In conclusion, infection and thrombosis has been
the major drawbacks of hemodialysis catheterization, and
repeated catheterization should be avoid for the high occurance
of venous stenosis.
