Fluoroscopic placement of nasojejunal feeding tubes in COVID-19 patients in the prone position

Application and effectiveness of an improved endoscopically guided nasojejunal tube placement technique in critically ill patients: a retrospective cohort study

Background

The endoscopic nasojejunal (NJ) placement plays a pivotal role in the nutritional support of critically ill patients. However, the conventional endoscopy-guided tube insertion method presents issues of excessive procedural duration. We have enhanced the traditional endoscopy-guided catheter placement method, enabling a faster and more convenient catheter insertion.

Methods

We improved the traditional endoscopically guided technique by incorporating an extra silk thread knot at the 25 cm mark on the jejunal segment of the NJ tube to assist endoscopists in accurate tube placement. We conducted the improved NJ tube placement on critically ill patients in need of enteral nutrition (EN). Laboratory data were retrospectively collected before and after the 7-day period of NJ tube placement and EN treatment to evaluate the effectiveness and safety of the improved method.

Results

A total of 88 critically ill patients, with an average age of 59.6±15.5 years, and a male ratio of 86.4%, who underwent the improved NJ tube placement method were enrolled into analysis finally, achieving a 100% success rate of NJ tube insertion. The average time for tube insertion was 5.9±2.2 min, with a mean insertion depth of 108.8±12.5 cm. The EN tolerance score was 0.79±0.98. Following 7 days of EN therapy, the patients showed significant improvement in serum albumin levels compared to baseline (36.42 vs. 33.66 g/L, P<0.001).

Conclusions

The improved endoscopically guided NJ tube placement technique is a rapid and safe procedure with excellent patient tolerance. It significantly improves the nutritional status of critically ill patients and facilitates the administration of EN, which requires further validation through randomized controlled trials.

A multifaceted comparative analysis of image and video technologies in gastrointestinal endoscope and their clinical applications

This paper presents a comprehensive exploration of endoscopic technologies in clinical applications across seven tables, each focusing on a unique facet of the medical field. The discourse begins with a detailed analysis of pediatric endoscopes, highlighting their diagnostic capabilities in various conditions. It then delves into the specifications and applications of globally recognized capsule endoscopy devices. Additionally, the paper incorporates an analysis of advanced imaging techniques, such as Narrow Band Imaging (NBI), Flexible Spectral Imaging Color Enhancement (FICE), and i-scan, which are increasingly being integrated into ultrathin gastrointestinal (GI) endoscopes. Factors like technological capabilities, light source, camera technology, and computational constraints are evaluated to understand their compatibility with these advanced imaging techniques, each offering unique advantages and challenges in clinical settings. NBI, for instance, is lauded for its user-friendly, real-time enhanced imaging capabilities, making it effective for early detection of conditions like colorectal cancer and Barrett's esophagus. Conversely, FICE and i-scan offer high customizability and are compatible with a broader range of endoscope models. The paper further delves into innovative advances in movement control for Nasojejunal (NJ) feeding tube endoscopy, elucidating the potential of AI and other novel strategies. A review of the technologies and methodologies enhancing endoscopic procedure control and diagnostic precision follows, emphasizing image and video technologies in pediatric endoscopy, capsule endoscopes, ultrathin endoscopes, and their clinical applications. Finally, a comparative analysis of leading real-time video monitoring endoscopes in clinical practices underscores the continuous advancements in the field of endoscopy, ensuring improved diagnostics and precision in surgical procedures. Collectively, the comparative analysis presented in this paper highlights the remarkable diversity and continuous evolution of endoscopic technologies, underlining their crucial role in diagnosing and treating an array of medical conditions, thereby fostering advancements in patient care and clinical outcomes.

Innovative strategy to improve enteral nutrition in prone positioning with patients with COVID-19

BACKGROUND

Enteral nutrition is essential to improve outcomes in patients who are critically ill. Patients in the prone position, including those diagnosed with coronavirus disease 2019 (COVID-19) present additional challenges for enteral nutrition initiation.

METHODS

A novel technique for placing feeding tubes while in the prone position was developed using an electromagnetic placement device and specialty trained clinical nurse specialists. Data were assessed retrospectively to determine effectiveness of this new practice.

RESULTS

Sixty-eight patients had feeding tubes placed while in the prone position; 75% were able to be placed through the postpyloric route, 22% were placed through the gastric route, and 3% unable to be placed. Use of this technique facilitated earlier initiation of feedings by 2 days from time of admission and almost half a day from intubation to feeding. There was no additional radiation exposure from using this technique.

CONCLUSION

Ability to place feeding tubes early while patients were prone reduced delays for starting enteral nutrition. Patients with COVID-19 in the prone position were able to receive effective nutrition support earlier with no additional complications.

Cost-effectiveness analysis of nasojejunal tube feeding for the prevention of pneumonia in critically ill adults

BACKGROUND

Nasojejunal tube (NJT) feeding has demonstrated value in reducing pneumonia in critically ill adults who require enteral nutritional (EN) support. This study discusses whether EN support via nasojejunal tube (NJT) feeding is more cost-effective than nasogastric tube (NGT) feeding in reducing pneumonia.

METHODS

A decision tree model was created. The analysis was based on data from a health care provider in China. Model inputs were derived from published data. The endpoints included incremental cost per pneumonia infection avoided, incremental cost-effectiveness ratio (ICER), net monetary benefit (NMB) and incremental net monetary benefit (INMB) associated with prevention of pneumonia. The uncertainty was assessed through one-way and probabilistic sensitivity analysis.

RESULTS

The base case analysis showed that EN support via NJT feeding resulted in 0.7453 quality-adjusted life years (QALYs) at a cost of $3018.83 compared to NGT feeding, which resulted in 0.7354 QALYs at a cost of $4788.76. NJT feeding was better than NGT feeding, providing an INMB of $2,075.09 and an ICER of $-178,813.96 per QALY gained, and the cost per pneumonia infection prevented was $16,808.51. The probabilistic sensitivity analysis indicated that NJT feeding was more cost-effective in 83.4% of the cases, with a cost below the WTP threshold. The NMB and INMB estimation for different WTP thresholds also indicated that NJT feeding is the optimal strategy.

CONCLUSIONS

EN support via NJT feeding was a more cost-effective strategy than NGT feeding in preventing pneumonia in critically ill adults. This article is protected by copyright. All rights reserved.

Fluoroscopic placement of nasojejunal feeding tubes in COVID-19 patients in the prone position

Background

Coronavirus disease 2019 (COVID‐19) has caused an increase in patients requiring enteral feeding access while undergoing proning for severe acute respiratory distress syndrome (ARDS). We investigated the safety and feasibility of fluoroscopy‐guided nasojejunal (NJ) feeding tube placement in the prone position.

Methods

This is a retrospective cohort study of all patients who underwent fluoroscopic placement of NJ feeding tubes at a single institution between March 2020 and December 2020. Primary end points were success rate and number of attempts. Chi‐squared and Fischer exact tests were used to compare prone and supine groups.

Results

A total of 210 patients were included in the study: 53 patients received NJ feeding tubes while prone and 157 while supine. All but one patient in the prone group had ARDS secondary to COVID‐19, whereas 47 (30.3%) had COVID‐19 in the supine group. The rate of successful placement was 94.3% in the prone group and 100% in the supine group. Mean number of attempts was 1.1 (SD, ±0.4) in the prone and 1.0 (SD, ±0.1) in the supine group (P = .14). Prone patients had a longer median fluoroscopy time (69 s, interquartile range [IQR] = 92; vs 48 s, IQR = 43; P < .001) and received a higher radiation dose during the procedure (47 mGy, IQR = 50; vs 25 mGy, IQR = 33; P = .004). No procedural complications were reported.

Conclusion

Fluoroscopy‐guided NJ feeding tube placement in prone patients is feasible and safe. Patient positioning should not delay obtaining postpyloric feeding access.
