First you need to get exact weights (in grams/kilograms) on each snake because dosage will be determined by the snake's weight. The normal dosage is 5 to 8 mg/kg. The normal strength of Baytril injectible is 56.8 mg/ml. So for a snake that weighs 1 kg., dosage will be from .09 to about .16 cc, a range of .10 to .14 being a safe midpoint range. You will need to use a .5cc or 1cc syringe to get an accurate dose.
How to actually administer the intramuscular injection:
You will need either restraining tubes or two people for this.
1. use the syringe to draw the appropriate dose of medication from the vial, then pointing the needle upward, tap the side of the syringe so all the little air bubbles form one bubble at the base of the needle, then slowly push the plunger in until the air is forced out of the needle.
2. either place the snake in a restraining tube with an injection slot in the side or have someone else control the snake while you give the injection.
3. Locate the muscle in between the spine and the ribs in the first 1/3 of the snake's body. This will be the injection site.
4. angle the needle toward the snake's head at such an angle as to be able to stay in the muscle with the needle and not punch through the abdominal wall. Keep your fingers off the plunger until you are ready to actually inject the medicine.
5. quickly and firmly insert the needle into the muscle, then pull back slightly on the plunger. If blood flows into the syringe, pull the needle back out, move the injection site just a little and push the needle back in. When no blood flows into the syringe if you pull back on the plunger, then go ahead and push the plunger to inject the medicine.
6. That's it...go ahead and pull the needle out and discard it in an appropriate fashion.
