tetanus immunoglobulin
Học thuậtThân thiện
Definition
Noun: - A sterile solution containing antibodies (immunoglobulins) obtained from the blood plasma of a human donor who has been immunized against tetanus. It is used to provide immediate, short-term protection against tetanus infection following a potential exposure to the tetanus bacterium.
Usage
- Medical Treatment: Used as a form of passive immunization. It is administered, often by injection, to individuals with a wound or injury that poses a risk of tetanus infection, especially if their own vaccination status is incomplete or unknown.
- Context: Primarily used in emergency medicine, wound care, and travel medicine.
Examples
- The doctor administered tetanus immunoglobulin immediately after the patient's deep puncture wound from a rusty nail.
- In addition to cleaning the wound, the protocol calls for a dose of tetanus immunoglobulin for unvaccinated individuals.
- Tetanus immunoglobulin provides temporary antibodies to neutralize the toxin until the body can respond to the tetanus vaccine given at the same time.
Advanced Usage
- Abbreviation: Often abbreviated as TIG in medical charts and literature.
- The patient's record notes that TIG was administered in the ER.
- Distinction from Vaccine: It is crucial to distinguish this from the tetanus vaccine (toxoid). The immunoglobulin provides immediate, temporary protection (passive immunity), while the vaccine stimulates the body's own long-term antibody production (active immunity). They are often given concurrently for post-exposure prophylaxis.
