Hello Dr. Rynne,, my nieces husband was bitten on the left hand yesterday by a rattlesnake. They live in San Diego. He received medical Tx quickly. So far he has been administered just over 20 vials of anti venom. He is in ICU, BP is a little elevated, HR in 70 s, and still having many muscle contractions. There concern is now turned toward the kidneys/failure. Is this normal to take this much anti venom before beginning to see improvement? Scott Landis / YYYY@YYYY
