Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The administration of sedation with midazolam or fentanyl could be a confounding factor in the diagnosis of cervical facet joint pain in patients with chronic neck pain. However, if =80% pain relief with the ability to perform prior painful movements is used as the diagnostic standard, the effect of sedation on validity may be extremely low. In contrast, a significant number of patients may present as false-positives if =50% pain relief with ability to perform prior painful movements is used as the diagnostic criteria. | — |
Secondary
| Measure | Time frame |
|---|---|
| Prudent administration of midazolam only to patients who are not relaxed may not have significant adverse effect on the diagnostic validity of controlled comparative local anesthetic blocks. On the other hand, fentanyl could confound the diagnosis with false-positive results in a significant proportion of patients. | — |
