Nupercaine - General Information:

A local anesthetic of the amide type now generally used for surface anesthesia. It is one of the most potent and toxic of the long-acting local anesthetics and its parenteral use is restricted to spinal anesthesia. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1006)

Pharmacology:

Nupercaine is an amide-type local anesthetic, similar to lidocaine.

Additional information about Nupercaine

Nupercaine Indication: For production of local or regional anesthesia by infiltration techniques such as percutaneous injection and intravenous regional anesthesia by peripheral nerve block techniques such as brachial plexus and intercostal and by central neural techniques such as lumbar and caudal epidural blocks.
Mechanism Of Action: Local anesthetics block both the initiation and conduction of nerve impulses by decreasing the neuronal membrane's permeability to sodium ions. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.
Drug Interactions: Methotrexate The NSAID increases the effect and toxicity of methotrexate
Lithium The NSAID increases serum levels of lithium
Acenocoumarol The NSAID increases the anticoagulant effect

Absorption: In general, ionized forms (salts) of local anesthetics are not readily absorbed through intact skin. However, both nonionized (bases) and ionized forms of local anesthetics are readily absorbed through traumatized or abraded skin into the systemic circulation.

Letter from Virginia Apgar to F. W. Clement (April 25, 1938)
Similar cases have been reported with all other drugs used in spinal anesthesia, ie procaine and its various combinations, nupercaine, stovaine etc. May I suggest that you publish this case soon, so that others like it may come to light. The mechanism of the paralysis is of course difficult to explain.

The anaesthetist sterilizes his scalp and injects it with Nupercaine to produce analgesia – the patient will remain fully conscious throughout the procedure. Behind the surgical drapes, three large incisions are made in his scalp.
