A breath of fresh air: a quality-improvement study comparing an air-circulating technique versus conventional technique to prevent nasogastric tube dysfunction

Aspiration pneumonia in nursing literature-a mapping review

Introduction

Aspiration pneumonia (AP) is an infection of the lungs caused by inhalation of material. The reported incidences vary across literature and clinical populations and is associated with high morbidity and mortality. Management of AP is best carried out by a multidisciplinary team.

Methods

This aim of this review was to collate and describe the available evidence on AP to develop a greater understanding of the concept of AP as it is represented in the nursing literature. As a collaborative team, we undertook the six stages of a systematic mapping review. We searched for the term aspiration pneumonia in 200 peer reviewed nursing journals across 10 databases, over a ten-year period (2013-2023).

Results

In this review, 293 papers were coded. Dysphagia, oral health and tube feeding emerged as the most frequent risk factors for AP, and the most reported factors for preventing this condition. Mortality was the most commonly described consequence of AP, followed by hospitalisations and morbidity. Multiple management approaches were reported including dysphagia assessment, risk evaluation, oral care and texture modification of food and fluids. The role of nurses and interprofessional collaborations were described.

Discussion

Despite limited evidence related to the topic of AP in the nursing literature, the complexity of the causes, prevention, management and consequences of AP emerged. Certain factors, such as dysphagia, oral health, and tube feeding, were described under prevention, cause and management of AP. The importance of multidisciplinary approach in the management and prevention of AP was presented.

Preclinical trial of the effectiveness of a safety nasogastric tube to detect the tube position based on tidal volume and pepsin assay results in the gastrointestinal tract of Macaca fascicularis

BACKGROUND

Tube misplacement into the tracheobronchial tract is associated with pneumothorax in 0.5% of cases. NGT verification only detects the position of the tube at the end of the procedure. Therefore, a safe nasogastric tube (SNGT) was created to detect the NGT position in real time in a simple and inexpensive way. This study aimed to prove the effectiveness of the SNGT prototype in Macaca fascicularis.

RESULT

An SNGT producing 50% of the TV had 100% sensitivity and specificity in detecting the position of the tube at 100% of the TV, with a sensitivity of 100% and a specificity of 87.5%. There was a significant difference between the movement of the SNGT 50% TV and SNGT 100% TV airbags (p ≤ 0.05). However, there was no significant difference between the accuracy of placement of the 50% TV SNGT, 100% TV SNGT, and conventional NGT (p > 0.05). The pepsin enzyme had better sensitivity (100%) than pH paper (91.66%) in detecting the end-of-procedure tube position. This research has the potential to advance into human clinical trials.

CONCLUSION

SNGTs are highly effective in detecting the NGT position inside the respiratory and digestive tracts to prevent misplacement.

Sumping's Up: A Multidisciplinary Educational Initiative on Gastric Drainage Tubes

BACKGROUND

Nasogastric tube placement is widely taught, and tube maintenance relies on astute nursing care with adherence to both institutional and evidence-based recommendations. However, precise adherence to current recommendations relies on knowledge base regarding the identification of malfunctioning gastric drainage tubes. Troubleshooting skills are crucial in maintaining patient safety and recognizing malfunction.

METHOD

Educational sessions on nasogastric and orogastric decompression tube management, led by a surgical intensive care fellow at a level 1 trauma center, were offered to critical care nurses. A presession and postsession survey evaluated the nurses' subjective and objective knowledge and comfort with naso/orogastric decompression tube management.

RESULTS

Ninety-seven critical care RNs participated. For all questions, the proportion of correct answers significantly increased from presession survey to postsession survey (p < .001). Ninety-seven percent of all participants found the session to be very helpful.

CONCLUSION

Physician-led educational sessions on naso/orogastric decompression tube management were well-received and improved subjective and objective measurements of nurses' knowledge and comfort level with gastric decompression tubes. [J Contin Educ Nurs. 2020;51(10):484-488.].
