Brief Summary
This research is being done to see if there is a difference between two different spinal anesthetics (Mepivacaine vs. Bupivacaine) as it relates to reducing post-operative complications and the time it takes for subjects to regain mobility after surgery.

Outcome Measures
Primary Outcomes (1)
Time to Return of Lower Extremity Motor Function
Assessed by measuring time from spinal anesthetic administration to postoperative achievement of Bromage 0 function (return of spontaneous ankle, knee, and hip movement) in the non-operative extremity at 15-minute intervals.
Post surgery, approximately 1 day
Secondary Outcomes (8)
Post-Anesthesia Care Unit (PACU) Length of Stay
Time of discharge, approximately 1-2 days
Hospital Length of Stay
Time of discharge, approximately 1-2 days
Maximum Pain Score
24 hours following the surgical procedure
Median Pain Score
24 hours following the surgical procedure
Discharge Pain Score
Time of discharge, approximately 1-2 days
- +3 more secondary outcomes
Study Arms (2)
Low-Dose Bupivacaine
ACTIVE COMPARATORSubjects in this group will be given 10mg of Low-Dose Bupivacaine, which is within standard of care for spinal anesthesia during TKA or THA.
Mepivacaine
ACTIVE COMPARATORSubjects in this group will be given 70mg of Mepivacaine, which is within standard of care for spinal anesthesia during TKA or THA.
Interventions
10 mg (2 mL of 0.5%) administered as an isobaric spinal anesthetic
Eligibility Criteria
You may qualify if:
- American Society of Anesthesiologists (ASA) physiological status I-III (patient must meet criteria of a status I-III in the ASA Physical Status Classification System: I=Normal Healthy Patient, II=Mild Systemic Disease, and III=Severe Systemic Disease)
- Unilateral primary TKA or THA
- + years of age
- Able to provide informed consent
You may not qualify if:
- Chronic pain syndromes such as fibromyalgia or complex regional pain syndrome
- Chronic opioid use (\>1 mos) with OME \>5 mg/day OR acute opioid use (\< 1 mos) with OME \> 30 mg/day.
- Body mass index (BMI) \> 45 kg/m2
- Severe drug allergy\* to medications used in this study, including non-steroidal anti-inflammatory drugs (i.e. celecoxib and ketorolac), and local anesthetics (defined as an immune reaction resulting in shortness of breath, hives, anaphylaxis, wheezing, and fever)
- Major systemic medical comorbidities such as:
- Pre-existing severe renal disorder defined as glomerular filtration rate (GFR) \<50 units/m2 (if labs are available), currently on dialysis, or highly suspected based on history.
- Severe hepatic disorder defined as current or past diagnosis of acute/subacute necrosis of liver, acute hepatic failure, chronic liver disease, cirrhosis (primary biliary cirrhosis), chronic hepatitis/toxic hepatitis, liver abscess, hepatic coma, hepatorenal syndrome, other disorders of liver
- Contraindication to spinal anesthesia technique (e.g., known spinal stenosis, coagulopathy, sepsis, infection at site of injection, uncooperative, refusal, anticoagulation medications not held within appropriate time frame\*). \*Per ASRA guidelines, Clopidogrel (Plavix) held for at least 7 days, Dabigatran (Pradexa) held for at least 5 days, Rivaroxaban (Xarelto)held for at least 3 days, Warfarin (Coumadin)held for at least 5 days or recent INR of less than 1.4, Enoxaparin (Lovenox) with doses \> 1 mg/kg held for close to 24 hours.
- Known to be currently pregnant or actively breastfeeding. Patients that have a previous history of menopause, hysterectomy, or tubal ligation will not be required to perform a pregnancy test. Female patients that do not meet this criterion will be asked to submit a urine sample, and will require a negative urine sample in order to proceed with study protocol. Urine sample be collected pre-procedurally.
