Insights
The Enhanced Protein-Energy Provision via the Enteral Route Feeding Protocol (PEP uP) improved protein delivery in surgical patients but faced implementation challenges. This critical care nutrition strategy may also increase vomiting rates.
Area of Science:
- Critical care medicine
- Surgical nutrition
- Intensive care unit (ICU) management
Background:
- The Enhanced Protein-Energy Provision via the Enteral Route Feeding Protocol (PEP uP) is known to be effective but understudied in surgical/trauma patients.
- Critically ill surgical and trauma patients often require specialized nutritional support to optimize outcomes.
Purpose of the Study:
- To evaluate the efficacy of the PEP uP protocol in increasing energy and protein delivery to critically ill surgical/trauma patients.
- To assess the feasibility and safety of implementing the PEP uP protocol in this patient population.
Main Methods:
- A multicenter, prospective, randomized pilot study involving adult surgical patients requiring mechanical ventilation and ICU care.
- Patients were randomized to either the PEP uP protocol or standard care.
- The PEP uP protocol involved early initiation, specific formulas, prokinetics, volume-based goals, and modular protein.
Main Results:
- The study was terminated early due to slow recruitment.
- PEP uP patients received significantly more protein (106.8 vs 78.5 g/d).
- No significant difference in energy delivery was observed; vomiting was more frequent in the PEP uP group (32% vs 12%).
- Protocol violations were noted in the PEP uP group regarding medications, feeding volume, and protein supplementation.
Conclusions:
- The PEP uP protocol showed potential for improving protein delivery in surgical/trauma patients.
- Successful implementation of the PEP uP protocol was challenging, with several deviations from the intended protocol.
- The protocol may be associated with an increased risk of vomiting in this patient population.
Background:
The Enhanced Protein-Energy Provision via the Enteral Route Feeding Protocol (PEP uP) has been shown to be feasible, safe, and effective in delivering significantly more energy/protein, though it has not been well studied in surgical/trauma patients. We hypothesized that PEP uP will effectively increase energy/protein delivery to critically ill surgical/trauma patients.
Methods:
This multicenter, prospective, randomized pilot study included adult patients admitted to surgical service who were expected to require mechanical ventilation for >24 hours and intensive care unit (ICU) care for >72 hours. Subjects were randomized to PEP uP or standard care. The PEP uP protocol includes initiation at goal rate, semi-elemental formula, prophylactic prokinetic agents, 24-hour volume-based goals, and modular protein supplementation. The primary outcome was nutrition adequacy over the first 12 ICU days.
Results:
Thirty-six subjects were enrolled. Slow recruitment resulted in early trial termination by the sponsor. There were no baseline differences between groups. PEP uP patients received more protein (106.8 ± 37.0 vs 78.5 ± 30.3 g/d, P = 0.02). Energy delivery was not significantly different (1400.0 ± 409.5 vs 1237.9 ± 459.1 kcal, P = 0.25). Vomiting was more common in the PEP uP patients (32% vs 12%, P = 0.03). PEP uP protocol violations included 2 patients (15.4%) not receiving pro-motility medications, 3 (23.1%) not receiving volume-based feeds as ordered, and 4 (30.8%) not receiving supplemental protein.
Conclusions:
In surgical/trauma patients, PEPuP seemed to improve protein delivery but was difficult to implement successfully and may increase vomiting rates.

Drug Delivery: Enteral Route
Routes of Drug Administration: Enteral
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

Conservation of Energy in Control Volume
For steady flow systems, the time derivative of the stored energy becomes zero since there is no energy accumulation within the control volume. This simplifies the energy equation to:
