Nerve block anesthesia

Injection of a solution of a local anesthetic into or about individual peripheral nerves or nerve plexuses produces even greater areas of anesthesia than do the techniques described previously. Blockade of mixed peripheral nerves and nerve plexuses also usually anesthetizes somatic motor nerves, producing skeletal muscle relaxation, which is useful for some surgical procedures.

Clinical use Mepivacaine has been employed for all types of infiltration and conduction nerve block anesthesia using solutions of 1.0 and 1.5 % lasting for 1.5 to 3 h. Epidural anesthesia with 2.0 % mepivacaine has a rapid onset with a dense motor block. Hyperbaric solutions of mepivacaine have also been used for spinal anesthesia (Tetzlaff, 2000). Mepivacaine has been used for topical applications, but other LA such as lidocaine are more effective. 

Most patients can easily tolerate this treatment without nerve block anesthesia if the peel is done slowly, cosmetic unit by cosmetic unit. More squeamish patients may prefer to have intravenous sedation, along with nerve blocks. 

Raised telangiectasias may become more visible in patients with thin and transparent skin. Facial telangiectasias can be electrocoagulated immediately before the phenol is applied, while the patient is under nerve-block anesthesia for the peel. An Elhnan radiofrequency unit is completely satisfactory in this indication.

Fintsi recommended simple intravenous sedation without FNB he used promethazine and morphine sulfate (5-15 mg) and titrated the doses until the burning sensation subsided. According to him, nerve block anesthesia is not essential with this procedure, but, without the FNB, the patient is in pain during the peel and this makes it uncomfortable for both the patient and the doctor. The patient only has a vague memory of the pain. Asken reported on a study by Litton showing an accelerated heartbeat slowing down when deep sedation is combined with nerve block anesthesia.

Phenol is neurolytic it makes the skin less sensitive for several days, and it is possible to touch up certain areas without causing any real pain after the nerve block anesthesia has worn off, even the day after the peel. Even if deep inflammatory phenomena make the dermis painful, the epidermis remains insensitive. 

Peripheral nerve block anesthesia involves injecting the drug near the nerves close to the area to be anesthetized. Epidural anesthesia results when the local anesthetic is injected into the epidural space between a lumbar and sacral vertebra. Several drugs can safely produce useful levels of anesthesia for obstetrics as well as postoperative pain. Another method of utilizing local anesthetics is to inject solutions into subarachnoid spaces (e.g., the spaces between certain vertebrae). 

Bupivacaine (e.g., Marcaine) Infiltration, spinal, epidural, and nerve block anesthesia. Long duration increases utility for epidural block during labor. Similar to lidocaine. IV administration may induce ventricular arrhythmias. 

Well, an American surgeon William Stewart Halsted used cocaine injections to invent nerve-block anesthesia in 1884. Sadly, he was to become a cocaine addict. Sigmund Freud, inventor of psychoanalysis, pioneered the use of cocaine as a local anesthetic for eye surgery (now replaced by lidocaine or benzocaine), and cocaine became briefly available in over-the-counter medications for treatments of complaints like toothache or catarrh. But cocaine was generally banned in North America and Europe toward the end of the nineteenth century. Around this time, the fictional detective Sherlock...
