Citocinas e anestesia

Abstract

JUSTIFICATIVA E OBJETIVOS: Vários trabalhos têm abordado as citocinas que podem ser estimuladas e liberadas por lesão cirúrgica, trauma, infecção, inflamação e câncer. Níveis elevados circulantes das citocinas parece ter implicações no aparecimento de complicações e retardo da recuperação pós-operatória de pacientes. O objetivo da presente revisão é resumir as informações hoje disponíveis sobre citocinas. CONTEÚDO: As citocinas são moléculas polipeptídicas produzidas por uma grande variedade de células e parecem não ter função na homeostase, sob condições normais. Esses mediadores são responsáveis por respostas locais ou sistêmicas, gerando alterações imunológicas, metabólicas, hemodinâmicas, endócrinas e neurais. Podem ativar respostas biológicas benéficas, como estimulação da função antimicrobiana, cicatrização de feridas, mieloestimulação e mobilização de substratos. No entanto, a secreção abundante de citocinas está associada a efeitos deletérios como hipotensão arterial, falência de órgãos e morte. CONCLUSÕES: Ao concluir esta revisão, fica evidente que as citocinas desempenham um papel de fundamental importância como mediadores de respostas metabólicas, hormonais, imunológicas e hematológicas, que há potencial terapêutico com o bloqueio de sua expressão e que a anestesia pode interferir de alguma forma na sua ativação. No entanto, muitas perguntas não estão ainda respondidas e estudos devem ser realizados nos próximos anos buscando esclarecer as ações das citocinas não só para a experimentação mas também para a prática clínica.
