Patient information material

|
|
Target number of participants
|
180 subjects, randomized into 3 groups with equal distribution
|
|
Interventions
|
Intravenous injection of sodium chloride solution, midazolam, or fentanyl prior to lumbar facet joint nerve blocks under fluoroscopy.
|
|
Primary outcome measure(s)
|
For a small proportion of patients with chronic low back pain, the administration of sedation with midazolam or fentanyl can be a confounding factor in the diagnosis of lumbar facet joint pain. The study shows that an intravenous preoperative sedative dose of a narcotic such as fentanyl or an anxiolytic such as midazolam is no more likely to cause a small proportion of patients to report false positive pain relief with active motion testing than sodium chloride placebo.
|
|
Secondary outcome measure(s)
|
The study suggests that prudent administration of midazolam or fentanyl to patients who are not relaxed may not have any significant adverse effect on the diagnostic validity of controlled comparative local anesthetic blocks.
