Does topical lidocaine reduce blood flow?

Reductions of blood flow ranged from 19.3% for 1% lidocaine HCl to 77.8% for 2% lidocaine HCl with epinephrine. Epinephrine by itself significantly reduced nerve blood flow; when added to local anesthetic solutions, it reduced nerve blood flow to a greater extent than the reduction caused by anesthetics alone.

Why does EMLA cause vasoconstriction?

In healthy subjects, EMLA cream produced a biphasic vascular response with an initial vasoconstriction, maximal after 1.5 h of application. After prolonged application (greater than 3 h, vasodilatation occurred, presumably because of a smooth muscle relaxant effect of the analgesics.

How does lidocaine affect the cell membrane?

Lidocaine alters signal conduction in neurons by prolonging the inactivation of the fast voltage-gated Na + channels in the neuronal cell membrane responsible for action potential propagation. With sufficient blockage, the voltage-gated sodium channels will not open and an action potential will not be generated. Careful titration allows for a high degree of selectivity in the blockage of sensory neurons, whereas higher concentrations also affect other types of neurons.

How long does lidocaine work?

When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours. Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area. It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding.

Does lidocaine inhibit vasoconstrictors?

The vasodilator properties of lidocaine are believed to be due mainly to the inhibition of action potentials via sodium channel blocking in vasoconstrictor sympathetic nerves. However, mechanisms involving the vascular endothelium may also play a role, and in this study we investigated the potential influences of nitric oxide release, the cyclo-oxygenase pathway and the beta-adrenoceptors of vascular smooth muscle. Laser Doppler imaging was used to measure microvascular blood flow responses to intradermal injection of lidocaine 2%, with or without the addition of preservatives, in eight healthy, male volunteers. Co-injection of the nitric-oxide-synthase inhibitor Nomega-nitro-L-arginine methyl ester caused a 60% reduction in the response after about 20 min, and this reduction was enhanced with the lidocaine solution containing the preservatives methylhydroxybenzoate and propylhydroxybenzoate. No reduction in response was seen after blocking the cyclo-oxygenase or beta-adrenoceptor pathways. Nitric oxide release contributes to the vasoactivity of lidocaine in human skin.

Can you use lidocaine and oxymetazoline together?

A topical vasoconstrictor such as oxymetazoline can also be used either as a separate spray or mixed with the lidocaine to shrink mucosal membranes and constrict blood vessels. This will reduce risk of epistaxis during the procedure and open the nasal cavity to allow easier passage of the device.

The state of the chosen site also influences serum ...

Does a vasoconstrictor increase the concentration of local anesthetics?

The maximum safe dosage of local anesthetics, whether topical or injected, is generally increased when used in combination with a vasoconstricting agent. Serum concentration increases at a slower rate when blood flow is diminished at the site of treatment as the anesthetic is sequestered. This same process will increase the duration of analgesic effect for a given anesthetic when administered along with a vasoconstrictor (Berde & Strichartz, Catterall & Mackie, Drasner, Hilal-Dandan & Brunton, Schwartz & Kaufman).

There have been few controlled clinical studies of topical anesthetics because it is difficult to design objective techniques to evaluate the quality of local anesthesia.

The specifics of their use have been described previously and will be only briefly discussed here [5].

Which combination of tetracaine and oxymetazoline provides superior nasal anesthesia to cocaine?

We conclude that the combination of tetracaine and oxymetazoline provides superior nasal anesthesia to cocaine and the combination of lidocaine and oxymetazoline.

How to make anesthetic solution?

The lido/oxy mixture was prepared by mixing 5 mL of 4% lidocaine with an equal volume of 0.05% oxymetazoline yielding a final concentration of 2% lidocaine and 0.025% oxymetazoline. The tetra/oxy mixture was prepared by dissolving 20 mg of tetracaine in 2 mL of 0.05% oxymetazoline, yielding a final concentration of 1% tetracaine and 0.05% oxymetazoline. The cocaine used was in a 4% solution. A cottonoid pledget (1.3 times 3 cm) was saturated with local anesthetic solution. Each pledget absorbed approximately 0.5 mL of solution. The medicationsoaked pledget was placed in the nasal cavity against the septum at time 0 and removed at 10 min.

What is the best alternative to cocaine for nasal anesthesia?

Few other local anesthetics have been widely used to provide topical nasal anesthesia. Lidocaine and tetracaine are the most commonly chosen alternatives to cocaine, but must be mixed with a vasoconstrictor to provide optimal surgical conditions. Our previous study [5] demonstrated that the combination of lidocaine and oxymetazoline was as efficacious as cocaine in providing intranasal anesthesia and vasoconstriction. Other studies [9,10] have shown that oxymetazoline and cocaine have similar vasoconstrictive effects when applied intranasally.
