Indirect calorimetry can be used to measure cardiac output in septic patients?

Abstract: Purpose: The aim of this study was to compare two different cardiac output (CO) monitoring systems based on the thermodilution principle (Thermo-CO) and indirect calorimetry (Fick mixed-CO) in septic patients. Methods: Prospective study in septic patients admitted in an intensive care unit of a university hospital. Nineteen patients aged on average 45.4 ± 21.5 years were enrolled in the study. Four series of hourly measurements by the two techniques were carried out simultaneously. Results: No significant diff… Show more

“…This finding strongly suggests that leptin stimulates angiogenesis in the connective tissue beneath the ulcer, and promotes wound healing in the skin by accelerating the supply of nutrients, oxygen and even some bioactive substances. This result was consistent with some previous studies on the wound healing of rabbits [ 23 ] and rats [ 28 ].…”

“…One possibility is that leptin promotes wound healing by enhancing the epithelial cell proliferation [ 24 , 29 ]. Another possibility is that leptin promotes it by stimulating the angiogenesis [ 9 , 10 , 28 ]. Interestingly, another previous study showed that leptin was induced in wound tissue during the first few days following injury and affected wound repair process [ 33 ].…”

“…Bir diğer transpulmoner teknik, lityum dilüsyonu (LİDCO) olup KD'nin değerlendirilmesinde kullanılabilir ancak özel indikatör gerektirmesi ve GEDV ve EVLW gibi parametrelerin beraberinde ölçülemeyişi kullanımını sınırlamaktadır (1,24) . Yine invaziv teknikler arasında yer alan modifiye Fick prensibine dayalı indirekt kalorimetri yöntemi ile mekanik ventilasyon desteği alan hastalarda metabolizmada tüketilen O 2 ve üretilen CO 2 hesaplamalarıyla KD ölçümü yapılabilir (27) . Ancak ölçümler için ek aparat gerektirmesi ve güvenilirliğinin termodilüsyon yöntemlerine göre daha az olması dezavantajları arasındadır ve diğer parametrelerin ölçümüne izin vermez.…”

“…De acordo com este princípio, o débito cardíaco é obtido pelo consumo de oxigênio divido pela diferença arteriovenosa do conteúdo de oxigênio (Debito cardíaco = Consumo de oxigênio/ Diferença arteriovenosa de oxigênio). O débito cardíaco em pacientes sépticos, obtido pelo consumo de oxigênio pela calorimetria indireta, tem uma boa correlação com o método invasivo do Swan-Ganz(AUXILIADORA-MARTINS et al, 2008).Durante a fase aguda do choque séptico, ocorre um estado hiperdinâmico caracterizado por taquicardia, aumento do débito cardíaco, e redução da resistência vascular periférica. Estas mudanças cardiovasculares interferem com o prognóstico destes pacientes.…”
