cat panting
Introduction
Introduction Open the arteriovenous vein and gently press to stop bleeding. The vein should be pulsated immediately, and the cat can be swollen, indicating that the blood flow is smooth, and the arteriovenous fistula shunt is completed. There is an abnormal channel between the artery and the vein called the arteriovenous fistula. As the normal blood vessels of the arteries flow into the accompanying veins, local vasculopathy of the tendon and hemodynamic changes in the local, peripheral circulation and systemic system of the tendon can be caused. Can be congenitally present or acquired due to trauma.

Doppler echocardiography
Indications:
1, acute renal failure without urine or oliguria for more than 2 days, urea nitrogen greater than 90mg or creatinine greater than 6mg have obvious symptoms of uremia.
2, chronic renal failure, serum creatinine 6 ~ 10mg, endogenous creatinine clearance rate is less than 10ml / min and moderate uremia symptoms.
Vascular selection: The basic requirement for vascular selection is that the vascular connection channel used must be easy to handle and handle, and can withstand frequent application. The shunt pathway can ensure blood flow of more than 200ml/min, has little effect on circulation and does not hinder the patient's activity. The commonly used blood vessels are: radial artery-cephalic vein, posterior tibial artery-associated vein, dorsal artery-sacro-adhesive vein and other blood vessels away from the heart, so as to reduce the burden on the heart. If necessary, the abdominal wall can be used to move and vein. However, the radial artery-cephalic vein is preferred.
Anesthesia: 1% to 2% procaine local anesthesia.
