Abstract
Sepsis represents a serious risk to the life of any patient, which is why it is crucial to start an effective treatment in all its extremes as soon as possible, that is, the chosen antibiotics must have activity against the pathogen that produces the condition and, in addition, they must be dosed considering the patient's situation in all its extremes. It should be considered that it will be necessary to adjust the dose when there is edema (drugs with reduced volume of distribution), hypoproteinemia (drugs bound to proteins in a high proportion), obesity, and also when they require the use of external techniques such as ECMO or any of the different types of hemodialysis and hemofiltration.
