Polocaine (Mepivacaine Infiltration) - Summary



3% Polocaine® Dental
(mepivacaine hydrochloride Injection, USP)
2% Polocaine® Dental
with Levonordefrin 1:20,000
(mepivacaine hydrochloride and levonordefrin Injection, USP)

Mepivacaine hydrochloride is a local anesthetic available as sterile isotonic solutions (clear, colorless) in concentrations of 1%, 1.5% and 2% for injection via local infiltration, peripheral nerve block, and caudal and lumbar epidural blocks.

Mepivacaine hydrochloride is related chemically and pharmacologically to the amide-type local anesthetics.

POLOCAINE (Mepivacaine HCl Injection, USP), is indicated for production of local or regional analgesia and anesthesia by local infiltration, peripheral nerve block techniques, and central neural techniques including epidural and caudal blocks.

The routes of administration and indicated concentrations for mepivacaine are:

local infiltration

0.5% (via dilution) or 1%

peripheral nerve blocks

1% and 2%

epidural block

1%, 1.5%, 2%

caudal block

1%, 1.5%, 2%

See DOSAGE AND ADMINISTRATION for additional information. Standard textbooks should be consulted to determine the accepted procedures and techniques for the administration of mepivacaine.

Published Studies Related to Polocaine (Mepivacaine Infiltration)

Triple-blind randomized clinical trial of time until sensory change using 1.5% mepivacaine with epinephrine, 0.5% bupivacaine, or an equal mixture of both for infraclavicular block. [2012]
by 20% or more versus 0.5% bupivacaine alone (bupivacaine)... CONCLUSIONS: Mixing 1.5% mepivacaine (with epinephrine) with 0.5% bupivacaine

Submucous tramadol increases the anesthetic efficacy of mepivacaine with epinephrine in inferior alveolar nerve block. [2011.05.07]
The purpose of this study was to evaluate the effect of submucous tramadol as adjuvant of mepivacaine with epinephrine in inferior alveolar nerve block. A double-blind, randomized, placebo-controlled, crossover clinical trial was conducted...

Efficacy of liposome-encapsulated mepivacaine for infiltrative anesthesia in volunteers. [2011.03]
This blinded crossover study evaluated the efficacy and pain sensitivity evoked by a previously reported liposome-encapsulated mepivacaine formulation (Araujo et al., 2004). Thirty healthy volunteers received an intraoral injection (1.8 mL), at four different sessions, of the following formulations: 2% mepivacaine with 1:100,000 epinephrine (MVC(2%EPI)), 3% mepivacaine (MVC(3%)), and 2 and 3% liposome-encapsulated mepivacaine (MVC(2%LUV) and MVC(3%LUV))...

The effect of mixing 1.5% mepivacaine and 0.5% bupivacaine on duration of analgesia and latency of block onset in ultrasound-guided interscalene block. [2011.02]
BACKGROUND: Short- and long-acting local anesthetics are commonly mixed to achieve nerve blocks with short onset and long duration. However, there is a paucity of data on advantages of such mixtures. We hypothesized that a mixture of mepivacaine and bupivacaine results in a faster onset than does bupivacaine and in a longer duration of blockade than does mepivacaine... CONCLUSIONS: For ultrasound-guided interscalene block, a combination of mepivacaine 1.5% and bupivacaine 0.5% results in a block onset similar to either local anesthetic alone. The mean duration of blockade with a mepivacaine-bupivacaine mixture was significantly longer than block with mepivacaine 1.5% alone but significantly shorter than the block with bupivacaine 0.5% alone.

Ketorolac-mepivacaine lower uterine block for in-office endometrial ablation: a randomized, controlled trial. [2010.11]

CONCLUSION: Injectable ketorolac-mepivacaine anesthetic solution functions well as a deep paracervical block for in-office gynecologic procedures, with better postoperative pain control than mepivacaine-alone protocols.

Clinical Trials Related to Polocaine (Mepivacaine Infiltration)

Effect of Epinephrine on Systemic Absorption of Mepivacaine in Uremic Patients [Recruiting]
The aim of this study is to determine the effect of epinephrine on systemic absorption of local anaesthetic mepivacaine administered for brachial plexus block in uremic patients scheduled for creation or repair of an arteriovenous fistula. Furthermore, an impact of epinephrine on the central circulation and peripheral tissue oxygenation will be evaluated.

The Anesthetic Efficacy of 3% Mepivacaine Plus 2% Lidocaine With 1:100,000 Epinephrine for Lower Jaw Dental Injections [Recruiting]
The inferior alveolar nerve block (shot) is the most frequently used injection technique for achieving local anesthesia (numbness) for the teeth in the lower jaw. However, this injection does not always result in successful pulpal (tooth) anesthesia (patient felt pain). No study has combined mepivacaine and lidocaine anesthetics (numbing solutions) for this type of injection (shot). The investigators propose to compare an injection of mepivacaine followed by lidocaine to an injection of lidocaine followed by lidocaine to determine if there is a difference in effectiveness.

Study to Find Optimal Dose of Local Spinal Anesthetic (Mepivacaine) Combined With Narcotic (Fentanyl) For Knee Surgery [Recruiting]
Prolonged motor block and delayed ability to walk are limitations of spinal anesthesia in ambulatory (same-day) surgery. This can be improved by lowering the dose of local anesthetic (a medication that, when injected around nerves, blocks nerve conduction, resulting in numbness and weakness) used in the spine, but too low a dose can result in an incomplete block (inadequate anesthesia) in some patients. There is evidence that adding a low dose of fentanyl, a narcotic, to mepivacaine enhances the anesthetic effect. The purpose of this study is to determine the lowest dose of mepivacaine, a local anesthetic, when combined with fentanyl, for which spinal anesthesia is adequate for ambulatory knee arthroscopy.

Spinal Mepivicaine With Fentanyl for Outpatient Knee Arthroscopy [Recruiting]
The purpose of this study is to determine if the addition of intrathecal fentanyl to low dose mepivacaine spinal anesthesia provides adequate surgical anesthesia with shorter duration of motor blockade.

It is hypothesized that lower doses of spinal mepivacaine when combined with fentanyl will result in adequate surgical block for knee arthroscopy surgery with faster recovery and discharge compared to mepivacaine alone.

Ropivacaine vs Ropivacaine Plus Mepivacaine for Sciatic Block [Recruiting]
In loco regional anesthesia, much more than for general anesthesia, the choice of the product is largely left at the discretion of the practitioner. Two categories of local anesthetics are distinguished according to their pharmacodynamic characteristics: products with a short time of installation and a short duration period, and products with a longer delay of installation of the sensitive and motor block, but with a long-term duration. Indeed, the combined use of two products pharmacodynamically different seems to be of a practical interest.

This study provides a comparison of the onset of action of 30 ml of ropivacaine 0. 75% and 30ml of a mixture of ropivaca´ne 0. 75% associated with mepivaca´ne 1. 5% for the subgluteal sciatic nerve block. This is a prospective randomized double-blind study where the main criterion of judgment is the time of installation of a sensitive block compatible with surgery in the sciatic territory nerve. Fifteen patients per group were calculated to detect a 50% decrease of the onset of action in the combination group with a power of 90% and alpha to 5%, according to a previous pilot study. The secondary endpoints are the intensity and time of installation of the motor block, the duration of sensitive and motor block, the total dose of morphine administered within 48 hours, as well as its possible side effects.
