Tissue damage from extravasation depends on the concentration of the drug in the tissue. Therefore, the best extravasation treatment is for the medical staff to be vigilant and assess an infusion of a vesicant drug every 15-20 minutes or so. Even under those circumstances, extravasation can occur. If the vesicant drug that extravasates is a vinca alkaloid, warm packs are often applied to to the affected areas. The presiding physician is notified immediately of the extravasation, and should be told of the vesicant drug and the concentration given.
Streptococci are gram-positive aerobic organisms that cause many disorders, including pharyngitis, pneumonia, wound and skin infections, sepsis, and endocarditis. Symptoms vary with the organ infected. Sequelae include rheumatic fever and glomerulonephritis.
