Comparing Heavy Levobupivacaine With Enantiomeric Excess of 50% and Heavy Racemic Bupivacaine.
March 25, 2014 updated by: Cristália Produtos Químicos Farmacêuticos Ltda.
Comparative Study of Non-inferiority Between Heavy Levobupivacaine With Enantiomeric Excess of 50% (Bupivacaine S75: R25) and Heavy Racemic Bupivacaine (Bupivacaine S50: R50) in Spinal Anesthesia for Orthopedic Procedures in the Lower Limbs.
The purpose of this study is to compare the non-inferiority between Heavy Levobupivacaine with Enantiomeric Excess of 50% and Heavy Racemic Bupivacaine During Spinal Anesthesia for Orthopedic Procedures in the Lower Limbs.
Study Overview
Detailed Description
The Heavy Levobupivacaine with Enantiomeric Excess of 50% was developed to be a safe local anesthetic replacing the Heavy Racemic Bupivacaine.
This study will evaluate the non-inferiority regarding efficacy and safety of spinal anesthesia in orthopedic procedures.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time of latency for sensory block at T10 dermatome.
Time Frame: +/- 40 min after injection
|
Evaluate the sensory block at T10 after the anesthetic injection through sensory stimulation by needle.
|
+/- 40 min after injection
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Sensory block duration
Time Frame: +/- 3 hours
|
Verifying the duration of anesthesia from after puncture till the presence of positive sensitivity by needle stimulation region of the foot.
|
+/- 3 hours
|
Motor Block Evaluation
Time Frame: +/- 30 min
|
Motor block evaluation by Bromage Scale every five minutes after puncture till 20 minutes.
|
+/- 30 min
|
Maximum cranial dispersion verifying the largest metamer achieved.
Time Frame: +/- 45 min
|
Evaluated by needle stimulation every 2 minutes from the removal of post-puncture needle until the maximum extension time.
|
+/- 45 min
|
Evaluation of the cardiocirculatory and respiratory parameters
Time Frame: +/- 8 hours
|
Systolic and diastolic blood pressure (SBP and DBP), heart rate (HR), and oxygen saturation (SpO2) are evaluate during the study to measure the safety of cardiocirculatory and respiratory parameters
|
+/- 8 hours
|
Time of regression of motor block by Bromage Scale
Time Frame: +/- 9 - 10 hours
|
Will be measure the time of recovery of the motor block, the patient have to score note 4 of the Bromage Scale
|
+/- 9 - 10 hours
|
The residual analgesic effect
Time Frame: +/- 9-10 hours
|
Will be evaluated the end of the analgesic effect of the anesthetic solution when the patient asks for pain medication.
|
+/- 9-10 hours
|
Anesthetic failure
Time Frame: +/- 45 min
|
Evaluation of the anesthetic failure (if occur)
|
+/- 45 min
|
Adverse Events
Time Frame: +/- 8 - 12 hours
|
During the study will be evaluate the presence of adverse event due to the anesthetic.
|
+/- 8 - 12 hours
