NCT03838874

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 COMPARATOR

Subjects in this group will be given 10mg of Low-Dose Bupivacaine, which is within standard of care for spinal anesthesia during TKA or THA.

Drug: Low-Dose Bupivacaine

Mepivacaine

ACTIVE COMPARATOR

Subjects in this group will be given 70mg of Mepivacaine, which is within standard of care for spinal anesthesia during TKA or THA.

Drug: Mepivacaine

Interventions

10 mg (2 mL of 0.5%) administered as an isobaric spinal anesthetic

Low-Dose Bupivacaine

70 mg (3.5 mL of 2%) administered as an isobaric spinal anesthetic

Mepivacaine

Eligibility Criteria

Age18 Days+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

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.
  • Impaired cognition
