Epinephrine with lidocaine

Lidocaine and lidocaine with epinephrine are also considered safe during pregnancy. 

Iontophoresis of mepivacaine and lidocaine with epinephrine have been reported in human cadaver bladders and in clinical trials by Lugnani et al. [41], The study reported that the active electrode must be sited close to the geometric center of the bladder cavity in order to anesthesize the entire bladder. Siting the electrode close to the wall resulted in anesthesia of only that section of the bladder. 

Iontophoresis has been used to deliver local anesthetics in the field of dentistry. Gangarosa [45] reported the iontophoresis of a 2% solution of lidocaine, with epinephrine (1 100,000) for the local anesthesia for extraction of retained deciduous teeth. Iontophoresis has also been used to desensitize teeth [46]. 

Figure 19-9 Subcutaneous injection of 1% lidocaine with epinephrine at base of papilloma provides adequate anesthesia for excision.

To remove a pednnculated lesion, swab the area with alcohol, anesthetize the area of the lesion with a M to cc shallow snbcntaneons injection of 2% lidocaine with epinephrine, and grasp the tip of the lesion with a monse-tooth forceps. Pnll the lesion away from the skin and sever the base of the lesion with the hot tip of the cantery unit.The tip removes the lesion and canterizes the blood vessels at the same time. An eschar forms and falls off in 7 to 10 days. 

Comphcation rates increase with premedication at home, and pre-existing disease or risk factors, such as pregnancy, cardiovascular disease, and allergies. Articaine and lidocaine with epinephrine 1 200 000 were associated with a low incidence of comphcations (3.1 and 0%), whilst mepivacaine and articaine with adrenaline 1 100 000 caused the most frequent comphcations (7.2 and 6.1%) (SEDA-22,135).

Lidocaine with epinephrine (adrenaline) has a similar acid pH, but it is impossible to do a peel with lidocaine. Acidity is therefore not the only important parameter.

The most commonly used vasoconstrictors, the sympathomimetic drugs, are often added to local anesthetics to delay absorption of the anesthetic from its injection site. By slowing absorption, these drugs reduce the anesthetic s systemic toxicity and keep it in contact with nerve fibers longer, thereby increasing the drug s duration of action. Administration of lidocaine 1% with epinephrine results in the same degree of blockade as that produced by lidocaine 2% without the vasoconstrictor. 

Mepivacaine hydrochloride (Carbocaine) is longer acting than lidocaine and has a more rapid onset of action (3-5 minutes). Topical application is not effective. It has been widely used in obstetrics, but its use has declined recently because of the early transient neurobehavioral effects it produces. Adverse reactions associated with mepivacaine are generally similar to those produced by other local anesthetics. It can be used with epinephrine or levonordefrin (dental use only). 

Topical local anesthesia is often used for eye, ear, nose, and throat procedures. Satisfactory topical local anesthesia requires an agent capable of rapid penetration across the skin or mucosa, and with limited tendency to diffuse away from the site of application. Cocaine, because of its excellent penetration and local vasoconstrictor effects, has been used extensively for ear, nose and throat (ENT) procedures. Cocaine is somewhat irritating and is therefore less popular for ophthalmic procedures. Recent concern about its potential cardiotoxicity when combined with epinephrine has led most otolaryngology surgeons to switch to a combination containing lidocaine and epinephrine. Other drugs used for topical anesthesia include lidocaine-bupivacaine combinations, tetracaine, pramoxine, dibucaine, benzocaine, and dyclonine.

Lidocaine (lignocaine) is an amide local anesthetic that is approved (2% solution, 20mg/ml) for use in horses. This agent is also used widely in humans and is available as 1% and 2% solutions also in combination with epinephrine (adrenaline) at a concentration of 1 in 200 000. 

Lidocaine is used in cardiovascular medicine for its antiarrhythmic properties (see Ch. 12). More recently, studies have looked at the i.v. administration of lidocaine to horses with colic (see Ch. 6). It appears that i.v. lidocaine (without epinephrine (adrenaline)) may have some desirable effects on jejunal distension and peritoneal fluid accumulation and is well-tolerated periop-eratively in horses with colic (Brianceau et al 2002). In addition, i.v. lidocaine reduced the halothane MAC significantly (Doherty Frazier 1998) in ponies. 

The posterior region of the scalp that concerns us is innervated by the occipital nerve of Arnold, which is easily blocked by an injection of 2% lidocaine with adrenaline (epinephrine). 

Gentle abrasion with sandpaper or intraepidermal erbium laser treatment help accelerate penetration of the ETCA solution considerably. When sandpaper abrasion is used, a topical anesthetic should be applied (a swab with 2% lidocaine with adrenaline (epinephrine)) after the abrasion, before applying the acid. With an erbium laser, a nerve block or ring block is necessary. 

An intraepidermal abrasion is performed with positive keratinocyte touch . Applying an acid solution immediately after abrasion would be very painful, and a surface anesthetic must be applied with gauze pads soaked in 2% lidocaine with adrenaline (epinephrine) (with 10-15 minutes under plastic film to prevent evaporation). The anesthetic can be seen to be working as the adrenaline penetrates and causes vasoconstriction. The ETCA solution is applied carefully, and cloudy-white frosting may appear with the first coat of acid solution. As soon as cloudy-white frosting occurs, 0.5 g of post-peel mask cream should be applied per 10 cm x 10 cm of surface area treated " and the skin massaged. 

Nerve blocks can be given in cases of very painful outbreaks. A mixture of lidocaine with adrenaline (epinephrine) and ropivacaine or bupivacaine" can be used. In some cases, the doctor will have to prescribe opioids to relieve severe pain. However, treatment with opioids might well get rid of the pain but will not affect the itching. It could even aggravate the pruritus. The itching sometimes resists hydroxyzine and diphenhydramine. Asken reported that he once had to inject propanolol intravenously to relieve unbearable pruritus. 

Hyaluronidase has found applications as an additive to the anesthetic agents used for peribulbar anesthesia for vitreoretinal surgery. Combinations of hyaluronidase with bupivacaine [119], lidocaine and epinephrine [120], lignocaine and adrenaline [121], or lidocaine and bupivacaine [122] were judged very...
