Brief Summary

Echocardiography (cardiac ultrasound) is being used more often in the critical care setting for management of severe infection (septic shock). Early studies show echocardiography to be useful in these patients, but at this time, there are no good clinical trials to justify its use.

Our study goals/objectives are as follows:

1. To conduct an unblinded, two-group randomized controlled clinical trial to compare an echocardiography-guided resuscitation protocol with an Early Goal Directed Therapy (EGDT) protocol in patients with severe sepsis or septic shock.

2. Demonstrate that a sepsis treatment protocol using transthoracic echocardiography and other non-invasive assessments of cardiac output will result in more rapid resolution of septic shock compared to invasive EGDT.

3. Demonstrate patients receiving the non-invasive echocardiography protocol will receive less administration of intravenous fluid.

Conditions

• Blinding Strategy: NONE

Study Groups

Early Goal Directed Therapy (EGDT)

EGDT is currently standard of care in management of septic shock, so assignment to this treatment arm will confer no additional risk above that of standard of care. EGDT utilizes placement of a central venous catheter, an arterial catheter, and administration of intravenous fluid and vasoactive medications. EGDT uses central venous catheter to assess central venous pressure and ScVO2.

Group Type: ACTIVE_COMPARATOR

EGDT fluid resuscitation

Intervention Type: OTHER

Patients will have their fluid resuscitation care guided by an EGDT protocol, which is currently used as standard of care.

Echo Guided Fluid Resuscitation

The echo arm also utilizes placement of a central venous catheter, an arterial catheter, and administration of intravenous fluid and vasoactive medications, all of which are interventions found in standard care. The central venous pressure will not be monitored in this arm. Instead, decisions for giving fluids will be directed by the results of Echocardiography. Echocardiography poses no known risk to the patient, and it is non-invasive. The only risk of echocardiography is that of misdiagnosis.

Group Type: EXPERIMENTAL

Echo guided fluid resuscitation

Intervention Type: OTHER

Patients will have their fluid resuscitation care guided by measurements obtained during an echo.
