2005. Muscle weakness and malfunction have been described after continuous peripheral blockade, infiltration of wound margins, and peri- and retrobulbar blocks (It must be highlighted that the Stanford group demonstrated a significant increase in chondrocyte toxicity with the use of lidocaine and bupivacaine formulations that contained epinephrine at all doses and exposure times. It is important for the administering radiologist to understand the properties of the various pharmaceutic preparations available because there is considerable variability in their effectiveness, duration of action, and potential for severe adverse effects.This article will review the common corticosteroid and LA preparations used in radiology departments, with particular emphasis on their potential for adverse effects and complications.Steroids have variable structures, functions, and sites of effect.

Interestingly, they believe that this finding may be secondary to the significantly lower pH in these formulations (All the above-reported studies were designed to assess the effect on cartilage by the large volumes of LA used in orthopedic practices. 92, No. Other immunization procedures should not be undertaken in patients who are on corticosteroids, especially in high doses, because of possible hazards of neurological complications and lack of antibody response.The use of dexamethasone sodium phosphate injection USP in active tuberculosis should be restricted to those cases of fulminating or disseminated tuberculosis in which the corticosteroid is used for the management of the disease in conjunction with an appropriate anti-tuberculosis regimen.If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary as reactivation of the disease may occur. 0000005999 00000 n
