I brought her in for vomiting. They ran blood work for infection. They performed a spinal tap to rule out meningitis. They gave her 1 mg of xanax for pain and her blood pressure dropped to 55 over 32 and they were beating on her chest to wake her up. They said she could have slipped into a coma or even died. I am wondering what could have caused this? Was this too much of a dosage? They released her just a couple of hours later and said she must have had this infection for awhile. Never told me what it was, just sent her home. Gave her an antibiotic injection and released her. I am very worried about her.
