tailieunhanh - Pharmacology in Rehabilitation 4th Edition

In one sense, pharmacology can be considered a “good news, bad news” scenario. The good news is that exciting and innovative changes in drug therapy continue to occur at lightning speed. The bad news is that it is often difficult for health care practitioners to stay abreast of this rapidly changing field. Oftentimes, drug therapies that were considered state-of-the-art only a few years ago are now outdated and replaced by more contemporary treatments. Hence, the fourth edition of this text has been revised extensively to reflect the science and practice of pharmacology, with particular emphasis on how drug therapy impacts patients receiving physical rehabilitation. Efforts were made to use the peer-reviewed literature to obtain. | Charles D. Ciccone III Ill II Pharmacology in Rehabilitation .Contemporary Perspectives in Rehabilitation Potential Interactions between Physical Agents and Therapeutic Drugs Listed here are some potential interactions between physical agents used in rehabilitation and various pharmacologic agents. It is impossible to list all the possible relationships between the vast array of therapeutic drugs and the interventions used in physical therapy and occupational therapy. However some of the more common interactions are identified here. Modality Cryotherapy Cold ice packs Ice massage Cold bath Vapocoolant sprays Desired Therapeutic Effect Decreased pain edema and inflammation Muscle relaxation and decreased spasticity Drugs with Complementary Synergistic Effects Anti-inflammatory steroids glucocorticoids nonsteroidal anti-inflammatory analgesics aspirin and similar NSAIDs Skeletal muscle relaxants Drugs with Antagonistic Effects Peripheral vasodilators may exacerbate acute local edema Nonselective cholinergic agonists may stimulate the neuromuscular junction Other DrugModality Interactions Some forms of cryotherapy may produce local vasoconstriction that temporarily impedes diffusion of drugs to the site of inflammation Superficial and deep heat Local application Hot packs Paraffin Infrared Fluidotherapy Diathermy Ultrasound Decreased muscle joint pain and stiffness Decreased muscle spasms Increased blood flow to improve tissue healing NSAIDs opioid analgesics local anesthetics Skeletal muscle relaxants Peripheral vasodilators Nonselective cholinergic agonists may stimulate the neuromuscular junction Systemic vasoconstrictors . alpha-1 agonists may decrease perfusion of peripheral tissues Systemic heat Large whirlpool Hubbard tank Decreased muscle joint stiffness in large areas of the body Opioid and nonopioid analgesics skeletal muscle relaxants Severe hypotension may occur if systemic hot whirlpool is administered to patients taking peripheral vasodilators and .
