Delayed Allergic Reaction to Secondary Administrated Epidural Hyaluronidase
نویسندگان
چکیده
We are reporting a rare case of a delayed hypersensitivity reaction caused by hyaluronidase allergy following a lumbar transforaminal epidural block. Using an intradermal skin test, we have provided evidence that the systemic allergic reaction resulted from hypersensitivity to hyaluronidase. To our knowledge, this is a rare case of a delayed hypersensitivity reaction to epidural hyaluronidase, comprised of an initial exposure to hyaluronidase with no subsequent allergic response in prior block followed by a subsequent delayed reaction to hyaluronidase during a second epidural block.

Anaphylactic Shock Caused by the Epidurally-Administered Hyalurinidase
Hyaluronidase is an enzyme that has temporary and reversible enzymatic effects on the matrix of connective tissue. When added to local anesthetics in pain treatments, it enhances their infiltration and dispersal into tissues. It is widely used in anesthesia for ocular, dental, and plastic surgery. Reports of drug hypersensitivity to hyaluronidase are rare and are usually confined to peribulbar ...
متن کاملAcute urticaria caused by the injection of goat-derived hyaluronidase
Hyaluronidase is a goat testicular protein that hydrolyzes hyaluronic acid, a structural component of the intercellular matrix. It is commonly used as a spreading factor to improve the diffusion of drugs, including local anesthetics and chemotherapeutics. We experienced a 55-yr-old female with generalized urticaria that developed within 1 hr after the epidural injection of hyaluronidase. She ha...
متن کاملAllergic reactions to hyaluronidase in pain management -A report of three cases-
Hyaluronidase has been gaining interest because it reduces tissue edema and fibrosis. Although rare, hyaluronidase has been shown to cause allergic reactions. A few cases of allergic reactions following hyaluronidase administration have been reported. Most of the described patients presented allergic reactions after peribulbar anesthesia for eye surgery. In this report, we describe three patien...

BACKGROUND Management of low back pain after spinal surgeries is one of the most challenging problems in pain medicine. Transforaminal lumbar epidural steroid injection has been used with inconsistent response. Most patients require multiple and frequent injections due to high recurrence of back pain. OBJECTIVE To find out whether the addition of hyaluronidase to the epidural injectate affect...
