Abstract:
Fentanyl has a low molecular weight and is lipophilic making it suitable for transdermal administration. However, multiple factors appear to lead to interindividual variation in absorption via this route. Here we describe an unusual case where a patient was found to have twelve 100 μg/hour fentanyl patches in situ which she was using as background analgesia.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
