Cuidados de segurança ao paciente na aplicação da toxina botulínica

Abstract

Botulinum Toxin (TB) is a toxin produced by the bacterium Clostridium botulinum, responsible for causing botulism and producing eight different serotypes, namely A, B, C1, C2, D, E, F and G. The toxin acts as a neuroparalytic in nerve endings, blocking neurotransmitters that cause muscle contracture. Although all serotypes have the ability to temporarily inhibit muscle contraction, serotype A is the most used in aesthetics due to its greater potency compared to the others. Although its application is very safe, it is possible to find negative reports after use, including headache, muscle weakness, eyelid ptosis and some more serious cases involving arrhythmia, myocardial infarction, seizures, respiratory failure, between others. Furthermore, drug interactions may occur in patients who have previously used some medicines, as well as causing immunogenicity during reapplications. Therefore, the responsible biomedical professional must be aware of the possible risks when applying the toxin, ensuring safety and a satisfactory result for the patient. [resumo fornecido pelo autor]
