Summary
Severe anaphylactic shock can occur from Patent Blue V, a dye used in oncological surgery. This case highlights diagnostic challenges and anesthetic management for this rare but serious adverse event.
Area of Science:
- Oncology
- Anesthesiology
- Clinical Pathology
Background:
- Patent Blue V is a widely used food dye.
- Its clinical application has expanded to oncological surgery for sentinel lymph node identification in various cancers.
- Sentinel lymph node biopsy aids in cancer staging and treatment planning.
Observation:
- A patient undergoing breast cancer surgery experienced severe anaphylactic shock following a subcutaneous injection of Patent Blue V.
- The dye is essential for visualizing lymphatic pathways during surgery.
- Immediate recognition and management of anaphylaxis are critical.
Findings:
- The study presents a case of severe anaphylactic shock attributed to Patent Blue V during oncological surgery.
- It details the clinical presentation and the anesthesiological interventions employed.
- Potential delays in diagnosis due to atypical presentations are discussed.
Implications:
- Anesthesiologists and surgeons must be aware of the risk of anaphylaxis from Patent Blue V.
- Prompt diagnosis and management are crucial for patient safety.
- This case underscores the importance of preparedness for adverse reactions to surgical dyes.

Allergic Reactions: Anaphylaxis
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...

Overview
Indicators
Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are called...
