What is the purpose of this trial?

This trial tests a tool called the Non-Invasive Cardiac Output Monitor (NICOM) to assist doctors in determining fluid levels for patients with septic shock. Septic shock occurs when an infection leads to dangerously low blood pressure, and NICOM aims to improve treatment by measuring the heart's response to fluids. The trial targets adult inpatients with sepsis-related low blood pressure or high lactic acid levels, indicating septic shock. As an unphased trial, participation offers a chance to contribute to innovative research that could enhance future treatments for septic shock.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that the Non-Invasive Cardiac Output Monitor (NICOM) is safe for use in septic shock patients?

Research has shown that the Non-Invasive Cardiac Output Monitor (NICOM) has been used safely in many studies, including with very sick patients, such as those in septic shock. These studies suggest that NICOM helps determine when and how much fluid to administer to a patient. Because NICOM is non-invasive, it doesn't require surgery, making it generally safer than surgical options. While more research is needed to refine NICOM's use, the safety results from studies so far are reassuring. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about using the Non-Invasive Cardiac Output Monitor (NICOM) for septic shock because it offers a new way to manage this severe condition. Unlike standard treatments that might rely on invasive methods for monitoring a patient's heart function, NICOM is non-invasive, meaning it can track cardiac output without the need for needles or catheters. This makes it less risky and more comfortable for patients. Additionally, by potentially providing real-time data on a patient's heart function, NICOM could help doctors make quicker and more informed decisions about treatment, which is crucial for managing septic shock effectively.

What evidence suggests that the NICOM is effective for septic shock?

Research has shown that the Non-Invasive Cardiac Output Monitor (NICOM), which participants in this trial will use, serves as a valuable tool for managing fluid levels in patients with septic shock. This device measures heart function, aiding doctors in determining the appropriate fluid volume a patient requires. Studies indicate that NICOM can enhance fluid management, a critical aspect of treating septic shock. It achieves this by adjusting fluid levels based on real-time changes, rather than relying on older, less flexible methods. Overall, early findings suggest that NICOM could improve fluid management in these patients, potentially leading to better outcomes. ^{1 3 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• NICOM

Trial Overview The trial is testing NICOM technology which measures heart function non-invasively to guide fluid resuscitation in patients with hypotension or septic shock from sepsis. The goal is to see if this method can effectively determine when fluids should be given compared to older methods like CVP and PCWP measurements.

How Is the Trial Designed?

Group I: Non-Invasive Cardiac Output Monitor (NICOM) Experimental Treatment 1 Intervention

The study measured cardiac output in 49 term infants using a non-invasive NICOM device at birth and 2 hours after birth, finding a significant decrease in cardiac output from 101 mL/kg/min at birth to 89 mL/kg/min at 2 hours (p<0.001).

The NICOM technique was found to be safe with no adverse effects reported, indicating its feasibility for monitoring cardiac output in newborns during delivery.

In a study involving 98 critically ill patients, cardiac output measurements from noninvasive cardiac output monitoring (NICOM) were found to be consistent with those obtained from ultrasound and pulse index continuous cardiac output (PiCCO), indicating that NICOM is a reliable method for hemodynamic monitoring.

The stroke volume index variation (∆SVI) calculated using NICOM's passive leg raising test effectively predicted volume responsiveness in patients with noncardiogenic circulatory shock, with a sensitivity of 88.37% and a specificity of 52.94%, demonstrating its clinical utility in managing fluid therapy.

The NICO monitor, which uses a non-invasive method to measure cardiac output, showed a moderate correlation (0.691) with the standard thermodilution technique in a study of 12 patients who had cardiac surgery, indicating it can be a useful tool for monitoring cardiac output.

However, the NICO monitor produced lower cardiac output measurements compared to thermodilution, especially at higher output levels, and is best suited for patients who are not breathing spontaneously and can tolerate a slight increase in carbon dioxide levels.

The NICOM Cheetah monitor can reliably track changes in cardiac output during surgery, but calibration shifts can occur, especially during upper abdominal procedures, leading to unpredictable changes in readings of over 1 L/min/m.

In a study involving 36 patients undergoing various surgical interventions, it was found that while NICOM generally trends well with Doppler methods, significant calibration shifts were noted in 72% of patients during upper abdominal surgeries, indicating a need for caution when interpreting NICOM data in these situations.

In a pilot study of 37 sepsis patients, combining the caval index and Noninvasive Cardiac Output Monitoring (NICOM) helped determine that at least 1000 mL of saline is necessary to significantly increase stroke volume in patients with a high caval index, while 500 mL was insufficient.

The study found no signs of fluid overload in any patients, suggesting that this fluid management approach is safe and may be beneficial in emergency settings for treating sepsis.

In a study of 50 patients with pulmonary hypertension, the NICOM® device provided more precise cardiac output measurements compared to traditional methods like thermodilution and Fick, with a coefficient of variation of 3.5% for NICOM versus 9.6% for thermodilution.

NICOM was able to reliably detect changes in cardiac output in response to vasodilator challenges, suggesting it could be a valuable noninvasive tool for monitoring patients with pulmonary hypertension and assessing their treatment responses.

The NICOM™ method for non-invasive cardiac output monitoring in neonates shows strong correlation with echocardiography measurements, indicating it can be a reliable tool for assessing cardiac function in this vulnerable population.

However, NICOM consistently underestimates left ventricular output compared to echocardiography, suggesting that while it is feasible, further validation is needed before it can be used routinely in clinical settings.

In a study of 50 adult emergency department patients at risk for sepsis, hemodynamic parameters from a non-invasive cardiac output monitor (NICOM) did not effectively predict disease severity or hospital admission compared to serum lactate levels.

Serum lactate was found to be a significantly better predictor of hospital admission and infection status, with an area under the ROC curve of 0.83, while cardiac output and other hemodynamic measures showed lower predictive values.
