The Use of Dantrolene to Improve Analgesia in Posterior Lumbar Surgery
March 22, 2023 updated by: Richard J. Pollard, Beth Israel Deaconess Medical Center
The purpose of this study is to determine whether administration of a non-centrally acting muscle relaxants will improve the Overall Benefit of Analgesia Score (OBAS), and Richmond Agitation Sedation Scale (RASS) scores in patients undergoing lumbar fusion.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Benefit of Analgesia Score (OBAS)
Time Frame: Measured at 24 hours after surgery
|
OBAS scores will be recorded on a scale from 0 (best outcome) to 28 (worst outcome).
|
Measured at 24 hours after surgery
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Benefit of Analgesia Score (OBAS)
Time Frame: Measured at 48 hours after surgery
|
OBAS scores will be recorded on a scale from 0 (best outcome) to 28 (worst outcome).
|
Measured at 48 hours after surgery
|
Richmond Agitation Sedation Scale (RASS)
Time Frame: Measured at 24 and 48 hours after surgery
|
The Richmond Agitation and Sedation Scale (RASS) is a validated and reliable method to assess patients' level of sedation in the intensive care unit.
Scores range from +4 (combative) to -5 (unarousable).
A score of 0 (alert and calm) is considered the best outcome.
|
Measured at 24 and 48 hours after surgery
|
Numerical Rating Scale (NRS) for Pain
Time Frame: Measured at 0, 1, 2, 3, 24, 48 hours after surgery
|
Pain scores will be recorded on a scale from 0 (best outcome) to 10 (worst outcome).
|
Measured at 0, 1, 2, 3, 24, 48 hours after surgery
|
ICU Length of Stay
Time Frame: Until discharge from the hospital, on average 24 hours
|
The length of the patients stay in the ICU will be measured in hours
|
Until discharge from the hospital, on average 24 hours
|
Hospital length of stay
Time Frame: Until discharge from the hospital, on average three days
|
The length of the patients stay in the hospital will be measured in days
|
Until discharge from the hospital, on average three days
|
Benzodiazepine use postoperatively
Time Frame: Until discharge from the hospital, on average three days
|
The number of patients who receive benzodiazepines after surgery will be recorded.
|
Until discharge from the hospital, on average three days
|
Morphine Equivalent Dose
Time Frame: Duration of the patient's stay in the hospital, on average three days
|
The postoperative analgesia requirement of narcotic medications during the patients recovery will be measured in morphine equivalent dose (miligrams)
|
Duration of the patient's stay in the hospital, on average three days
|
ICU Mobility Score
Time Frame: Measured at 24 and 48 hours after surgery
|
The patients ability to move will be recorded on a scale from 0 (nothing, lying in bed; worst outcome) to 10 (walking independently without a gait aid; best outcome).
|
Measured at 24 and 48 hours after surgery
