Indirect Calorimetry Usage and Effect in Ventilator-free Days and Muscle Thickness in Septic Ventilated Patients
October 21, 2020 updated by: Baylor Research Institute
Utilization of Indirect Calorimetry for Calculation of Nutritional Goals and Its Effect in Ventilator-free Days and Muscle Thickness in Septic Mechanically Ventilated Patients
Patients admitted to the ICU with diagnosis of sepsis and requiring mechanical ventilation for at least 24-hours and receiving enteral or parenteral nutrition will be prospectively randomized to one of two arms.
Patients allocated to the estimated energy expenditure group will receive nutrition with caloric intake calculated based on the Penn State equation.
Patients randomized to the measured group will receive nutrition with caloric intake calculated based on IC measurement present in the GE ventilator.
Patients in the estimated group will have IC performed, but these data will not be used for prescription of nutrition.
An equal number of beds within the ICU will be allocated to the measured group and the estimated group.
The primary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improvement in muscular structure, and consequent reduction of mechanical ventilation duration in patients with sepsis in comparison to utilizing the Penn State estimation equation for caloric goal calculation.
The secondary objective is to assess whether the utilization of indirect calorimetry for caloric goal calculation results in improved adequacy of nutritional delivery in comparison to the adequacy of nutritional delivered when utilizing the Penn State estimation equation.
Adult patients (> 18 years of age) admitted to the hospital with diagnosis of sepsis, and who require mechanical ventilation during hospitalization will be considered.
Patients newly ventilated for at least one day but less than three days will be included in the study.
Informed consent will be obtained from the legal authorized representative (LAR).

Detailed Description
Mechanically ventilated septic patients admitted to the ICU receiving enteral and or parenteral nutrition will be randomly allocated to one of the aforementioned groups.
Demographic information, parameters obtained from the ventilator, muscle measurements through ultrasonography, and clinical information, such as time spent on the mechanical ventilation, time spent in ICU and in the hospital will be collected.
Participants will enroll in the study upon admission to the ICU until one of the following occurs-patient is extubated, discharged from the ICU, or death with a maximum of 14 days of ICU admission.
Upon inclusion, IC will be assessed at baseline in all patients and then twice weekly.
Bedside ultrasonography of the diaphragm and quadricep muscle thickness will be performed upon enrollment of the study (within 3 days of MV and within 1 day of study enrollment) and repeated every 3-5 days with a minimum of twice weekly while on the MV.
Severity of illness score (APACHE IV), cause of sepsis, ventilator data, such as average tidal volumes and plateau pressures, cumulative and equivalent doses of sedatives (propofol, midazolam, lorazepam) and analgesics (fentanyl, hydromorphone) will be collected.
Presence of delirium during ventilation, based on ICU-CAM scores will be included, as well.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Measured Arm
Patients allocated to the measured energy expenditure (group M) will receive the intervention.
Caloric delivery will target results of IC measurement.
|
The prescribed calories to be delivered will be set to target the measurement obtained from performing indirect calorimetry (IC).
IC measures the gas exchange of oxygen consumption and carbon dioxide production to determine the true metabolic needs for cellular respiration.
The expenditure of calories will be measured utilizing the gas module incorporated within the General Electric Carescape R860 ventilators.
|
No Intervention: Estimated Arm
Patients allocated to the estimated energy expenditure (group E) will receive nutrition with caloric intake calculated based on the Penn State equation.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ventilator free days (VFD)
Time Frame: From current hospital admission date until the date of hospital discharge, date of death from any cause, whichever came first, assessed up to 28 days.
|
The number of days from day 1 to day 28 (of hospital admission) on which the patient was not on the mechanical ventilator.
If the patient expired or requires more than 28 days of mechanical ventilation, the value is zero.
|
From current hospital admission date until the date of hospital discharge, date of death from any cause, whichever came first, assessed up to 28 days.
|
Secondary Outcome Measures

Time Frame |
---|---|---|
Calorie and protein adequacy
Time Frame: Nutritional adequacy will be assessed from day one of ventilation in all patients until extubation from the MV or date of death, whichever came first, assessed up to 14 days.
|
Nutritional adequacy of caloric and protein delivery is measured as a ratio of the calories and protein received by the patient compared to the calories and protein prescribed during mechanical ventilation.
The ratios are determined individually for calories and protein.
|
Nutritional adequacy will be assessed from day one of ventilation in all patients until extubation from the MV or date of death, whichever came first, assessed up to 14 days.
|
Change in quadricep muscle thickness
Time Frame: Quadricep muscle thickness will be measured upon enrollment to the study (within 72 hours of MV) and every 3-5 days with a minimum of two times per 7 days until extubation from the MV or date of death, whichever came first, assessed up to 14 days.
