1. A method of providing local anesthesia to a mammal, comprising:
- (a) administering to said mammal in need thereof an anesthetic agent and an alpha adrenergic receptor agonist to the site to be anesthetized, wherein said anesthetic agent is administered in an amount effective to provide local anesthesia and said alpha adrenergic receptor agonist is administered in an amount effective to constrict the blood vessels at the site and prolong the local anesthesia, and then (b) administering a low dose of an alpha adrenergic receptor antagonist to said site to reduce the prolongation.

14. A method of providing local anesthesia to a human, comprising:
-
(a) administering to said human in need thereof by injection to the site to be anesthetized a solution comprising polocaine and levonordefrin, wherein said polocaine is administered in an amount effective to provide local anesthesia and said levonerdefrin is administered in an amount effective to constrict the blood vessels at the site and prolong the local anesthesia, thereby producing local anesthesia at said site, (b) carrying out a medical procedure on said human, and then (c) administering about 0.08 mg of phentolamine mesylate at said site at a concentration of about 0.05 mg/ml to reduce the prolongation.

16. A method of enhancing the survival of a tissue graft, comprising
(a) administering to a mammal undergoing a tissue graft an anesthetic agent and an alpha adrenergic receptor agonist to the site of the tissue graft, wherein said anesthetic agent is administered in an amount effective to provide local anesthesia and said alpha adrenergic receptor agonist is administered in an amount effective to constrict the blood vessels at the site and prolong the local anesthesia, (b) performing the tissue graft procedure, and then (c) administering an alpha adrenergic receptor antagonist to said site to reduce the prolongation and enhance the tissue graft survival.

21. A method of providing a regional anesthetic block to a mammal, comprising:
-
(a) administering to the mammal in need thereof an anesthetic agent and an alpha adrenergic receptor agonist in the site to receive the anesthetic block, wherein said anesthetic agent is administered in an amount effective to provide local anesthesia and said alpha adrenergic receptor agonist is administered in an amount effective to constrict the blood vessels in the site and prolong the anesthetic block, and then (b) administering an alpha adrenergic receptor antagonist to said site to reduce the prolongation. - View Dependent Claims (22, 23, 25, 26, 27, 28, 29, 30, 31, 32)
