Yoğun Bakımda Sepsis Olgusunda Endtidal Karbondioksitin İntravenöz Sıvı Yönetimine Katkısı
Özet
Bu yazıda, yoğun bakımda sepsis nedeniyle takip edilen bir olguda endtidal karbondioksit (EtCO₂) düzeyinin sıvı yanıtlılığını değerlendirmedeki rolü incelenmiştir. Sepsis hastalarında sıvı resüsitasyonunun dikkatli yapılması hayati önem taşırken, EtCO₂'nin noninvaziv, kolay ulaşılabilir ve uzmanlık gerektirmeyen bir ölçüm yöntemi olması nedeniyle önemi giderek artmaktadır. Olguda, EtCO₂ ile PaCO₂ arasındaki farkın artması pulmoner perfüzyon azalmasına işaret etmiş, pulmoner emboli düşünülmüş ancak sonrasında hipovolemi ve düşük kardiyak output gibi durumlar ön planda değerlendirilmiştir. EtCO₂'nin sepsiste sıvı yönetiminde bir gösterge olarak kullanılabileceği vurgulanmıştır.
This article investigates the role of end-tidal carbon dioxide (EtCO₂) monitoring in assessing fluid responsiveness in a case of sepsis followed in the intensive care unit. In septic patients, fluid resuscitation must be performed carefully, and EtCO₂ is gaining importance due to its noninvasive nature, easy accessibility, and lack of requirement for specialist equipment. In this case, the increased difference between EtCO₂ and PaCO₂ indicated decreased pulmonary perfusion, initially suggesting pulmonary embolism. However, hypovolemia and low cardiac output were later considered as primary factors. The case highlights the potential of EtCO₂ as a guiding tool in fluid management in sepsis.
