Step-by-step explanation:
The best procedure for placing a central line catheter in a schnauzer suffering from acute hypoglycemia requires a sterile technique and consideration of the dog's size and condition. The most common sites for central line placement in dogs include the jugular, femoral, or saphenous veins. A professional veterinarian will begin by preparing the selected site with an antiseptic solution, followed by the careful insertion of the catheter using ultrasound guidance if necessary, securing the catheter, and ensuring that it functions correctly for the infusion of glucose or other necessary medications.
