Trial Summary

What is the purpose of this trial?

The Non-Invasive Cardiac Output Monitor (NICOM) is a non-invasive monitor capable of measuring cardiac output (CO) and cardiac index (CI), and stroke volume (SV) and stroke volume index (SVI) based on heart rate. Conceptually NICOM is a technology that utilizes a dynamic response characteristic in assessing the need for fluid administration, whereby SVI is measured before and after a fluid challenge with more fluid given only if SVI increases significantly with administered fluid. Dynamic response technologies are intended to replace older, "static" measures such as central venous pressure (CVP) and pulmonary capillary wedge pressures (PCWP) which are single point measurements utilized to assess the need to administer fluid. The aim is to pilot and evaluate the effectiveness of using The Non-Invasive Cardiac Output Monitor (NICOM) technology for goal-directed fluid resuscitation in adult inpatients with sepsis associated acute hypotension and/or evidence of septic shock (Lactate \>= 4.0).

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 data supports the effectiveness of the treatment NICOM for septic shock?

Research suggests that NICOM, a non-invasive cardiac output monitor, can help manage fluid levels in patients with sepsis, which is related to septic shock. It has been used to predict disease severity and assess fluid responsiveness, which are important in treating septic shock. ^{1 2 3 4 5}

Is NICOM safe for use in humans?

NICOM, a non-invasive cardiac output monitor, has been used safely in various studies involving different patient groups, including critically ill patients, term infants, and those with pulmonary hypertension. While these studies primarily focus on its accuracy and feasibility, they do not report any significant safety concerns, suggesting it is generally safe for human use. ^{3 5 6 7 8}

How is the NICOM treatment different from other treatments for septic shock?

NICOM is unique because it is a non-invasive method that continuously monitors cardiac output (the amount of blood the heart pumps) using bioreactance technology, which helps guide fluid management in patients with septic shock. Unlike other treatments, it does not require invasive procedures and can provide real-time data to assess fluid responsiveness. ^{3 4 5 6 7}

Treatment Details

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.

Findings from Research

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.

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.

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 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 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 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.
