CE: Monitoring Adult Patients for Intolerance to Gastric Tube Feedings

Assessment for Enteral Feeding Intolerance by Critical Care Nurses: A National Survey

BACKGROUND

Enteral feeding intolerance (EFI) occurs in more than one-third of mechanically ventilated patients, yet the cause of this gastrointestinal dysfunction remains unclear. Assessment and diagnostic criteria are often vague and subjective leading to inaccurate recognition or diagnosis of EFI. Nurses are often unsure or unaware of appropriate assessment methods.

OBJECTIVES

The objective of this descriptive study was to determine current practice for assessment of EFI among critical care nurses.

METHODS

A national survey to explore EFI assessment practices was conducted with critical care nurses at the American Association of Critical-Care Nurses National Teaching Institute conference in 2022. Nurses completed a 19-item survey to determine assessment practices for EFI among critical care nurses.

RESULTS

A total of 344 nurses completed the survey. The majority of nurses practiced direct care at the bedside for adult critical care patients, held a bachelor's degree, had 6 to 15 years of nursing experience, and held specialty certification. There was variability among responses to the practice questions in the survey. Seventy-eight percent of the nurses were aware of and had cared for patients with EFI. EFI was assessed by 84% of participants. The most common assessment criterion for EFI was nausea and vomiting. The majority (81%) of respondents measured gastric residual volume routinely or sometimes.

DISCUSSION

This study shows assessment of EFI is not standardized among nurses. This study identifies a need for education about EFI given the lack of understanding of EFI. Findings from this study can be used to inform future research to develop best methods for assessing the presence of EFI.

Real-Time Camera Image-Guided Nasoenteric Tube Placement in Prone COVID-19 ICU Patients: A Single-Center Study

Background & Aims: This study aims to assess the application value of the real-time camera image-guided nasoenteric tube placement in critically ill COVID-19 patients undergoing endotracheal intubation and prone position ventilation therapy. Methods: We enrolled 116 COVID-19 patients receiving endotracheal intubation and prone position ventilation therapy in the intensive care unit (ICU). Patients were randomly divided into the real-time camera image-guided nasoenteric tube placement (n = 58) and bedside blind insertion (n = 58) groups. The success rate, placement time, complications, cost, heart rate, respiratory rate, Glasgow Coma Scale (GCS), and Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores were compared between the 2 groups. Results: For ICU patients with COVID-19 undergoing prone position ventilation therapy, the success rate and cost were significantly higher in the real-time camera image-guided group compared to the bedside blind group (P < .05). The placement time and complication incidence were significantly lower in the real-time camera image-guided group (P < .05). The differences in heart rate, respiratory rate, GCS scores, and APACHE-II scores were insignificant (P > .05). Conclusions: The real-time camera image-guided nasoenteric tube placement system had advantages for ICU COVID-19 patients undergoing prone position ventilation therapy, including a high success rate, short placement time, and no impact on patient position during tube placement. Real-time camera image-guided nasoenteric tube placement can be performed in any position, and demonstrates high efficiency, safety, and accuracy.

Using Nurse-Driven Protocols to Eliminate Routine Gastric Residual Volume Measurements: A Retrospective Study

BACKGROUND

Multiple critical care guidelines support the elimination of routine gastric residual volume monitoring in patients receiving enteral nutrition. However, transitioning nursing practice away from routine gastric residual volume assessments has proved challenging.

OBJECTIVE

To evaluate outcomes after the elimination of routine gastric residual volume monitoring in a 14-bed adult intensive care unit at a large teaching hospital in the southeastern United States.

METHODS

Practice change was accomplished through in-service training and implementation of a validated protocol. Data were collected for 30 days before and 30 days after protocol implementation to determine effects on the total volume of enteral nutrition received as well as the rate of adverse events after elimination of routine gastric residual volume assessments (n = 22) as compared with previous standard practice (n = 25).

RESULTS

When gastric residual volume was not measured, the mean (SD) percentage of enteral nutrition delivery was 81% (12%) of the ordered volume, compared with 60% (18%) in the historic control group (P = .002). Eliminating gastric residual volume monitoring was not associated with an increased rate of adverse events (emesis, aspiration pneumonia) or a change in length of stay. Nursing staff demonstrated a high degree of compliance with this protocol change.

CONCLUSION

The findings of this study indicate that the elimination of routine gastric residual volume assessment does not increase the rate of adverse events and results in increased nutrition provision. Use of a protocol for practice change as well as mandatory in-service training may effect changes in nursing practice.
