ICU CLINICAL PEARLS summarizes the experience of 40 years of life in the intensive care units where the sickest patients come or are sent in the hope to return to a life of reasonable quality. Arguably the safest place in the hospital. A place where any of your actions or decisions would make a tremendous difference in the life of these patients, but also a place where any mistake could cost a life. Therefore, we must apply a philosophy of perfection, of extremely safe care, and use our best science and deepest spirituality. Although we favor practice of evidence-based medicine, the fact that every patient has his/her own characteristics makes it impractical to do it solely with a scientific basis, and it yields to the clinical intuition that you can only obtain with experience and it makes the practice of critical care medicine not only a science, but also an art.
