benefit of intravenous, patient controlled (IV PCA) versus intravenous, intramuscular, and transdermal iontophoretic pain medication administration
Advantages and Disadvantages of Modes of Drug Administration
|IV PCA||Intermittent IV||Intramuscular||Transdermal Iontophoretic System|
|Access for the patient:||Readily available when needed||Needs trained personnel||Needs trained personnel||Easy, noninvasive|
|Bioavailability:||Good||Good||Depends on tissue perfusion||Depends on tissue perfusion|
|Risk of significant side effects:||Less likely of overdose||Overdose more likely||Overdose more likely, painful, risk of infection||Less likely overdose|
|Expense:||Expensive machine, low cost of maintenance||Potentially high administration cost||Potentially high administration cost||Only device cost|
