Abstract
The hypothesis was that anemia, independently of hemodynamic stability, affects tissue oxygenation saturation (StO2) and the deoxygenation rate during stagnant ischemia. The blood hemoglobin concentration is determinant of oxygen delivery. In anemic patients, oxygen delivery decreases and oxygen extraction is increased. This leads to decreased venous hemoglobin saturation and a lower tissue oxygen saturation. The rate of tissue deoxygenation during ischemia is dependent on oxygen consumption and on the amount of oxygen available in the tissue [1].
Highlights
There is considerable uncertainty about the reproducibility of the various instruments used to measure dyspnea, their ability to reflect changes in symptoms, whether they accurately reflect the patient’s experience and if its evolution is similar between acute heart failure syndrome patients and nonacute heart failure syndrome patients
The combined results demonstrate no statistically significant heterogeneity (P = 0.57, I2 = 0%) and no effect on mortality (OR = 1.02; 95% cardiac index (CI) = 0.93 to 1.11) with GIK treatment
Results of this study show that early tracheostomy, if perioperative complications
Summary
There is considerable uncertainty about the reproducibility of the various instruments used to measure dyspnea, their ability to reflect changes in symptoms, whether they accurately reflect the patient’s experience and if its evolution is similar between acute heart failure syndrome patients and nonacute heart failure syndrome patients. Conclusions Our data demonstrate that critically ill patients may be exposed to a higher FiO2 than that required to maintain adequate oxygenation These results highlight an area of ICU care that has received little study, with no published clinical trials examining the effect of FiO2 on outcome. Results Age, sex, the underlying disease and tumour stage (TNM classification), type of previous anticancer treatment, performance status, severity scores (APACHE II, Simplified Acute Physiology Score II, Sequential Organ Failure Assessment), ICU and hospital mortalities and hospital outcome at 3, 6 and 12 months were analysed. Clinical data of 277 post-transplantation patients admitted to the ICU were collected at admission and the SAPS 3 and APACHE II score calculated with respective estimated mortality rates.
