    <p>O excelente trabalho "Rela&#231;&#227;o entre Complac&#234;ncia Pulmonar Est&#225;tica e a Falha de Extuba&#231;&#227;o em Pacientes no P&#243;s-Operat&#243;rio de Cirurgia Card&#237;aca"<sup><xref ref-type="bibr" rid="B1">1</xref></sup> publicado nos Arquivos Brasileiros de Cardiologia, nos d&#225; mais uma ferramenta para auxiliar na decis&#227;o para permitir extuba&#231;&#227;o com sucesso mantido, no p&#243;s-operat&#243;rio de cirurgia card&#237;aca. Os autores estudaram 102 pacientes submetidos a diversas opera&#231;&#245;es card&#237;acas com circula&#231;&#227;o extracorp&#243;rea e observaram necessidade de reintuba&#231;&#227;o em 25 pacientes (24,51%) ap&#243;s 48 horas de extuba&#231;&#227;o. Os pacientes que falharam na extuba&#231;&#227;o tiveram complac&#234;ncia pulmonar mais baixa do que os que n&#227;o tiveram necessidade de serem reintubados. O ponto de corte da complac&#234;ncia pulmonar est&#225;tica para uma extuba&#231;&#227;o sem necessidade de reintuba&#231;&#227;o foi de 41 ml/ cm H<sub>2</sub>O, sendo o normal entre 60 e 100 ml/ cm H<sub>2</sub>O. Na an&#225;lise de regress&#227;o log&#237;stica m&#250;ltipla a falha de extuba&#231;&#227;o foi 9,1 vezes maior em pacientes com complac&#234;ncia pulmonar inferior a 41 ml/ cm H<sub>2</sub>O. Tamb&#233;m observaram que a complac&#234;ncia pulmonar est&#225;tica mais baixa foi acompanhada de pior troca gasosa. Recomendam que a medida da complac&#234;ncia pulmonar est&#225;tica deva ser inclu&#237;da na avalia&#231;&#227;o p&#243;s-operat&#243;ria do paciente submetido &#224; cirurgia card&#237;aca.</p>
    <p>Parte do material deste artigo integrou a disserta&#231;&#227;o de mestrado da Dra. Thais da Silva Brito, realizada sob a orienta&#231;&#227;o da Professora Doutora Desanka Dragosavac, na Universidade Estadual de Campinas.<sup><xref ref-type="bibr" rid="B2">2</xref></sup></p>
    <p>Necessidade de nova intuba&#231;&#227;o p&#243;s extuba&#231;&#227;o &#233; extremamente danosa e ocasiona maior tempo de UTI, maior tempo em respirador, maior tempo de interna&#231;&#227;o e maior mortalidade. A menor complac&#234;ncia pulmonar est&#225;tica e reintuba&#231;&#227;o s&#227;o demonstra&#231;&#245;es de piora cl&#237;nica e respirat&#243;ria. Evitar extuba&#231;&#227;o precoce &#233; importante para n&#227;o acrescentar problemas a um paciente em p&#243;s-operat&#243;rio de cirurgia card&#237;aca.<sup><xref ref-type="bibr" rid="B2">2</xref></sup></p>
    <p>Este trabalho merece alguns coment&#225;rios: 1 - Com um n&#250;mero maior de pacientes sendo extubados na sala de opera&#231;&#245;es, as medidas de complac&#234;ncia pulmonar est&#225;tica, fora do ambiente de pesquisa, deveriam provavelmente come&#231;ar a serem tomadas no centro cir&#250;rgico.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> 2 - O problema n&#227;o &#233; a reintuba&#231;&#227;o em si, mas sim a etiologia do problema que levou &#224; falha de extuba&#231;&#227;o. Seria interessante analisar o comportamento tardio da complac&#234;ncia pulmonar est&#225;tica e conhecer os motivos que levaram &#224; falha de extuba&#231;&#227;o.</p>
    <p>Atualmente muito se tem publicado sobre programas de melhor recupera&#231;&#227;o ap&#243;s cirurgia card&#237;aca (<italic>ERAS- Enhanced recovery after surgery</italic>) e a extuba&#231;&#227;o precoce faz parte destes estudos.<sup><xref ref-type="bibr" rid="B4">4</xref></sup> O importante, no entanto, n&#227;o &#233; a rapidez da extuba&#231;&#227;o, mas a adequa&#231;&#227;o para faz&#234;-lo no momento certo.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> Neste contexto a medida da complac&#234;ncia pulmonar est&#225;tica pode ser de grande valor na tomada de decis&#227;o a favor da extuba&#231;&#227;o precoce.</p>

      <p>The excellent paper "Relationship between static lung compliance and extubation failure in postoperative cardiac surgery patients"<sup><xref ref-type="bibr" rid="B1">1</xref></sup> published in the <italic>Arquivos Brasileiros de Cardiologia</italic> gave one additional tool to make more precise decisions for successful and maintained extubation in postoperative cardiac surgery.</p>
      <p>The authors have studied 102 patients submitted to several types of cardiac surgery under extracorporeal circulation and have found the need for reintubation in 25 patients (24,5%) after the first 48 hours of primary extubation. Extubation failure patients have had lower static lung compliance than non-failure patients. The cut-off point for the reintubation was a static lung compliance of 41 mi/cm H<sub>2</sub>O or lower, with a normal range between 60 and 100 ml/cm H<sub>2</sub>O. Using multiple regression analysis they had observed that extubation failure was 9,1 times greater in patients with static lung compliance equal to or less than 41 ml/cm H<sub>2</sub>O. They have also observed that lower static lung pulmonary compliance patients have worse oxygenation. They recommend that static lung compliance should be included in the postoperative evaluation of cardiac surgery patients, before extubation. This paper is part of the MSc thesis of Dr. Thais da Silva Bento, under the orientation of Dr. Desanka Dragosavac at the Universidade Estadual de Campinas.<sup><xref ref-type="bibr" rid="B2">2</xref></sup></p>
      <p>The need for new intubation in the postoperative cardiac surgery patient is extremely deleterious and may provoke more ICU time, more respirator time, greater admission time, and greater mortality. Lower static lung compliance and reintubation are demonstrations of clinical and respiratory compromise. To avoid too early extubation is mandatory to avoid problems to a postoperative cardiac surgical patient.<sup><xref ref-type="bibr" rid="B2">2</xref></sup></p>
      <p>Some remarks could be made on this paper: 1 - There is nowadays an increasing number of patients being extubated in the operating room at the end of the surgical procedure. Static lung compliance should probably be measured in the operating room at the end of the operation, before any attempt of extubation.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> 2 - The problem is not the reintubation by itself, but the reason why the reintubation was needed. It would be interesting to know the reasons for extubation failure and what was the late static lung compliance behavior.</p>
      <p>In recent times much has been published on enhancing recovery after surgery (ERAS) and early extubation is part of every ERAS protocol.<sup><xref ref-type="bibr" rid="B4">4</xref></sup> The important is not the rush for extubation, but the readiness to do so.<sup><xref ref-type="bibr" rid="B5">5</xref></sup> Static lung compliance measurement could be a valuable help in the early extubation decision.</p>
