Focused ultrasonography for septic shock resuscitation

Severe sepsis with septic shock is the most common cause of death among critically ill patients. Mortality has decreased substantially over the last decade but recent data has shown that opportunities remain for the improvement of early and targeted therapy. This review discusses published data regarding the role of focused ultrasonography in septic shock resuscitation.

Early categorization of the cardiovascular phenotypes with echocardiography can be crucial for timely diagnosis and targeted therapy of patients with septic shock. In the last few years, markers of volume status and volume responsiveness have been investigated, serving as valuable tools for targeting volume therapy in the care of both spontaneously breathing and mechanically ventilated patients. In tandem, investigators have highlighted findings of extravascular volume with ultrasonographic evaluation to compliment de-escalation of resuscitation efforts when appropriate. Furthermore, special attention has been given to resuscitation efforts of patients in septic shock with right ventricular failure.

Severe sepsis with septic shock is an insidious disease process that continues to take lives. In more recent years, data have emerged suggesting the utility of bedside ultrasonography for early cardiovascular categorization, goal directed resuscitation, and appropriate cardiovascular support based on its changing phenotypes.
