Evaluation of community nurse-led traumatic tube displacements.

Home enteral tube feeding (HEF) has many benefits and is largely safe practice. Some complications have historically required intervention in the acute setting, including traumatic displacement of feeding tubes (i.e. internal bumper/balloon removed intact), and evidence to support the safe replacement of these tubes in the community is lacking. To address this, a service enabling community homecare nurses (CHN) to replace traumatically displaced feeding tubes was designed and evaluated. Adult patients presenting with a traumatically displaced feeding tube over 29 months were included in the service evaluation. Baseline characteristics and outcomes at day 1, 7 and 6 months post-replacement were recorded. A total of 71 tube replacements were performed by CHNs in 60 patients. No clinical complications were recorded at any follow-up points. A simple cost analysis estimated savings of £235 754.40. These results suggest that nurse-led replacement of traumatically displaced feeding tubes in adults in the community is low-risk and offers potential cost savings.

Oral Drug Product Administration via Enteral Feeding Tubes: In Vitro Testing.

Medication administration via enteral feeding tubes (EFT) is a necessary practice for patients unable to swallow oral dosage forms due to a medical condition or treatment that affects the ability to swallow or the function of the gastrointestinal tract. Off-label administration of oral drug products via EFT raises concerns for pharmaceutical sponsors, regulators, and healthcare practitioners (HCPs) because of the potential risks this practice introduces to both the patient and the caregiver. These risks can be mitigated by generating data-supported instructions that patients and HCPs can use to ensure safe and accurate administration of oral drug products via EFT. This commentary presents an industry perspective on the testing that should be conducted to enable development of product-specific instructions in the labeling to support or advise against administration of oral drug products via enteral feeding tube. The proposal outlined in this commentary takes a risk-based approach, addressing recommendations from both regulatory agencies as well as considerations for expanding this testing to address needs specific to neonatal and pediatric populations.

A clinical consensus paper on jejunal tube feeding in children.

BACKGROUND: Feeding problems are common in children with complex medical problems or acute critical illness and enteral nutrition may be required. In certain situations, gastric tube feeding is poorly tolerated or may not be feasible. When feed intolerance persists despite appropriate adjustments to oral and gastric enteral regimens, jejunal tube feeding can be considered as an option for nutrition support. METHODS: A multidisciplinary expert working group of the Australasian Society of Parenteral and Enteral Nutrition was convened. They identified topic questions and five key areas of jejunal tube feeding in children. Literatures searches were undertaken on Pubmed, Embase, and Medline for all relevant studies, between January 2000 and September 2022 (n = 103). Studies were assessed using National Health and Medical Research Council guidelines to generate statements, which were discussed as a group, followed by voting on statements using a modified Delphi process to determine consensus. RESULTS: A total of 24 consensus statements were created for five key areas: patient selection, type and selection of feeding tube, complications, clinical use of jejunal tubes, follow-up, and reassessment. CONCLUSION: Jejunal tube feeding is a safe and effective means of providing nutrition in a select group of pediatric patients with complex medical needs, who are unable to be fed by gastric tube feeding. Appropriate patient selection is important as complications associated with jejunal tube feeding are not uncommon, and although mostly minor, can be significant or require tube reinsertion. All children receiving jejunal tube feeding should have multidisciplinary team assessment and follow-up.

Feasibility of a low-cost magnet tracking device in confirming nasogastric tube placement at point of care, a clinical trial.

An affordable and reliable way of confirming the placement of nasogastric tube (NGT) at point-of-care is an unmet need. Using a novel algorithm and few sensors, we developed a low-cost magnet tracking device and showed its potential to localize the NGT preclinically. Here, we embark on a first-in-human trial. Six male and 4 female patients with NGT from the general ward of an urban hospital were recruited. We used the device to localize the NGT and compared that against chest X-ray (CXR). In 5 patients, with the sensors placed on the sternal angle, the trajectory of the NGT was reproduced by the tracking device. The tracked location of the NGT deviated from CXR by 0.55 to 1.63 cm, and a downward tracking range of 17 to 22 cm from the sternal angle was achieved. Placing the sensors on the xiphisternum, however, resulted in overt discordance between the device's localization and that on CXR. Short distance between the sternal angle and the xiphisternum, and lower body weight were observed in patients in whom tracking was feasible. Tracking was quick and well tolerated. No adverse event occurred. This device feasibly localized the NGT in 50% of patients when appropriately placed. Further refinement is anticipated.ClinicalTrials.gov identifier: NCT05204901.

An externally validated guide to anatomical interpretation using a direct-vision ('IRIS') feeding tube.

BACKGROUND & AIMS: Most of the 11.5 million feeding tubes placed annually in Europe and the USA are placed 'blind'. This carries a 1.6% risk that these tubes will enter the lung and 0.5% cause pneumothorax or pneumonia regardless of whether misplacement is identified prior to feeding. Tube placement by direct vision may reduce the risk of respiratory or oesophageal misplacement. This study externally validated whether an 'operator guide' would enable novice operators to differentiate the respiratory and alimentary tracts. METHODS: One IRIS tube was placed in each of 40 patients. Novice operators interpreted anatomical position using the built-in tube camera. Interpretation was checked from recorded images by consultant gastroenterologists and end-of-procedure checks using pH or X-ray checked by Radiologists and a consultant intensivist. RESULTS: The 40 patients were a median of 68y (IQR: 56-75), 70% male, mostly medical (65%), conscious (67.5%) and 70% had no artificial airway. Three tubes were removed due to failed placement. In the remaining 37 placements, novice operators identified the airway in 17 (45.9%) and airway + respiratory tract in 19 (51.4%), but redirected all these tubes into the oesophagus. By using direct vision to reduce the proportion of tubes near the airway or in respiratory tract from 0.514 to 0, operator discrimination between the respiratory and alimentary tracts was highly significant (0.514 vs 0: p < 0.0001, power >99.9% when significance = 0.05). In addition, organ boundaries (respiratory tract vs oesophagus, oesophagus vs stomach, stomach vs intestine) were identified in 100%. CONCLUSIONS: Novice operators, trained using the guide, identified all respiratory misplacements and accurately interpreted IRIS tube position. Guide-based training could enable widespread use of direct vision as a means to prevent tube-related complications.

Nasogastric tube placement perforating the nasopharynx causing mediastinal passage and feeding into the pleural space.

A mid-60s female with known primary progressive multiple sclerosis was admitted to our hospital with aspiration pneumonia. Due to reduced consciousness, a nasogastric (NG) tube was inserted for feeding. A chest x-ray (CXR) report from a thoracic radiologist confirmed an atypical tip position due to a hiatus hernia but concluded it was almost certainly within the stomach. However, after deteriorating on feed commencement, a CT scan of the chest confirmed the tube had perforated the nasopharynx and run parallel to the oesophagus through the mediastinum into the right pleural space. The patient subsequently developed an empyema and pneumothorax, requiring multiple therapeutic interventions and a prolonged hospital stay. This case demonstrates how the routine insertion of an NG tube can lead to serious complications. Additionally, position check CXRs can be difficult to interpret, so the decision to use the tube must be made cautiously by the clinical team.

Differences in neonatal gastric tubes during insertion into a 3D model in relation to risk of potential perforation.

OBJECTIVES: Perforation of esophagus or stomach is a potential complication during and after insertion of a gastric tube in neonates. The aim of this study was to analyze different types of gastric tubes in a three-dimensional (3D) model of neonatal esophagus and stomach regarding potential perforations. METHODS: A 3D model of esophagus and stomach was created based on computed tomography data of a term neonate. Three types of gastric tubes were inserted into the 3D model, the localization was examined by radioscopy and the behavior, stiffness and manageability of each gastric tube was evaluated. RESULTS: Insertion of gastric tubes with higher stiffness was easier. The rates of correct localization differed significantly between the gastric tubes with the highest rate of correct localization in the softest tube (48.5%) and the lowest rate in the tube with the highest stiffness (21.2%). Additionally, the softest tube showed the lowest rate of localization of its tip at the stomach wall. CONCLUSIONS: The study illustrates differences between various types of gastric tubes regarding stiffness, behavior and resiliency. Softer gastric tubes may be beneficial. These differences may be relevant in neonatal care of very immature and very sick infants.

Placement of Nasogastric Tubes in Pancreaticoduodenectomy Patients: Switching from Immediate Intraoperative Removal to Avoiding Unnecessary Perioperative Use.

BACKGROUND: The placement of nasogastric tubes (NGTs) in abdominal surgery has been adopted for decades to attenuate ileus and prevent aspiration pneumonia. In the recent era, the guidelines recommend not using NGT routinely, and even in pancreaticoduodenectomy (PD), immediate removal of NGT in operating rooms (ORs) was suggested. However, the clinical outcome and safety of abandoning NGT during the pre-PD and intra-PD periods remain unknown. METHODS: We conducted a single-center retrospective review on adult PD patients aged between 20 and 75 years from 2013 to 2022. The study population was grouped into the NGT group (NGT was placed before PD and immediately removed in the ORs) and the non-NGT group (NGT was not placed preoperatively). Safety was evaluated by the number of adverse events. The primary aim of this study is to evaluate the need of NGT insertion in ORs among PD patients. RESULTS: The case numbers in the NGT and non-NGT groups were 391 and 578, respectively. No case in the non-NGT group needed the intraoperative insertion of NGT. The rate of pulmonary complications was 2.3% in the NGT group compared to 1.6% in the non-NGT group (P = 0.400). Furthermore, there were no significant differences in terms of rates of major complications (12.8% vs. 9.3%, P = 0.089) or mortality (1.0% vs. 1.0%, P =0.980) between the two groups. The rates of the postoperative insertion of NGT in the NGT and non-NGT groups were 2.6% and 2.8% (P = 0.840), respectively. CONCLUSION: For selected PD patients, the placement of NGT during pre-PD and intra-PD periods may be safely omitted. This primary study is considered the first foundation stone in the extension of the element of no NGT in PD.

Mal-positioned nasogastric feeding tubes: are medical students safe to identify them?

OBJECTIVES: Nasogastric tube (NGT) placement is listed against Clinical Imaging in the upcoming Medical Licensing Assessment-compulsory for every graduating UK medical student from 2025. This study aims to establish the ability of medical students to correctly identify the position of an NGT on Chest X-ray (CXR) and to evaluate a learning tool to improve student outcome in this area. METHODS: Fourth-year (MB4) and fifth-year (MB5) medical students were invited to view 20 CXRs with 14 correctly sited and 6 mal-positioned NGT. MB5 students (Intervention) were exposed to an online interactive learning tool, with MB4 students kept as control. One week later, both groups of students were invited to view 20 more CXRs for NGT placement. RESULTS: Only 12 (4.8%) of 249 MB5 students and 5 (3.1%) of 161 MB4 students correctly identified all the NGTs on CXRs. The number of students misidentifying 1 or more mal-positioned NGT as "safe to feed" was 129 (51.8%) for MB5 and 76 (47.2%) for MB4 students. This improved significantly (P < .001) following exposure to the learning tool with 58% scoring all CXRs correctly, while 28% scored 1 or more mal-positioned NGT incorrectly. Students struggled to determine if the NGT tip had adequately passed into the stomach. However, they failed to identify an NG tube in the lung ("never event") in just one out of 1,108 opportunities. CONCLUSION: Medical students' ability to determine if the NGT was in the stomach remains suboptimal despite exposure to over 60 CXRs. Feeding NGT should be formally reported before use. ADVANCES IN KNOWLEDGE: This is the first attempt at quantifying graduating medical students', and by inference junior doctors', competence in safely identifying misplaced nasogastric feeding tubes. An online, experiential learning resource significantly improved their ability.

Operative Complications Following Gastrostomy Tube Placement After Cardiac Surgery During Infancy.

INTRODUCTION: Gastrostomy tube (GT) placement is common in infants following repair of congenital heart defects. We aimed to determine rate of operative complications and predictors of short-term GT use to counsel parents regarding the risks and benefits of GT placement. METHODS: We reviewed infants aged <1 y with congenital heart disease who underwent GT placement after cardiac surgery between 2018 and 2021. Demographics and clinical data were collected and analyzed. Comparisons were made between infants who required the GT for more than 1 y and those who required the GT for less than 1 y. RESULTS: One hundred thirty three infants were included; 35 (26%) suffered one or more complication including wound infection (4, 3%), granulation tissue (3, 2%), tube dislodgement (10), leakage from the tube (9), unplanned emergency department visit (15), and unplanned readmission (1). Thirty-four infants used the GT for feeds for 1 y or less (26%) including 17 (13%) who used it for 3 mo or less. Fifty-six infants had their GT removed during the study period (42%), 20 of whom required gastrocutaneous fistula closure (36%). Thirty-three infants had a GT placed on or before day of life 30, 17 (52%) used the GT for less than 1 y, and 10 (31%) used it for 3 mo or less. CONCLUSIONS: GT placement is associated with a relatively high complication and reoperation rate. GT placement in infants aged less than 30 d is associated with shorter duration of use. Risks, benefits, and alternatives such as nasogastric tube feeds should be discussed in the shared decision-making process for selected infants.

Endoscopic and clinical features of gastric emphysema.

Gastric emphysema is characterized by the presence of intramural gas in the stomach without bacterial infection. Due to its rarity, most reports on gastric emphysema have been limited to single-case studies, and this condition's clinical and endoscopic features have not been thoroughly investigated. In this study, we analyzed 45 patients with gastric emphysema from 10 institutions and examined their characteristics, endoscopic features, and outcomes. The mean age at diagnosis of gastric emphysema in our study population (35 males and 10 females) was 68.6 years (range, 14-95 years). The top five underlying conditions associated with gastric emphysema were the placement of a nasogastric tube (26.7%), diabetes mellitus (20.0%), post-percutaneous endoscopic gastrostomy (17.8%), malignant neoplasms (17.8%), and renal failure (15.6%). Among the 45 patients, 42 were managed conservatively with fasting and administration of proton pump inhibitors. Unfortunately, seven patients died within 30 days of diagnosis, and 35 patients experienced favorable recoveries. The resolution of gastric emphysema was confirmed in 30 patients through computed tomography (CT) scans, with a mean duration of 17.1 ± 34.9 days (mean ± standard deviation [SD], range: 1-180 days) from the time of diagnosis to the disappearance of the gastric intramural gas. There were no instances of recurrence. Endoscopic evaluation was possible in 18 patients and revealed that gastric emphysema presented with features such as redness, erosion, coarse mucosa, and ulcers, with fewer mucosal injuries on the anterior wall (72.2%), a clear demarcation between areas of mucosal injury and intact mucosa (61.1%), and predominantly longitudinal mucosal injuries on the stomach folds (50.0%). This study is the first English-language report to analyze endoscopic findings in patients with gastric emphysema.

Enhancing Nutrition Support for Esophageal Cancer Patients: Understanding Factors Influencing Feeding Tube Utilization.

Objective: We sought to identify factors that can predict esophageal cancer (EC) patients at high risk of requiring feeding tube insertion. Methods: A retrospective cohort review was conducted, including all patients diagnosed with EC at our cancer center from 2013 to 2018. Multivariate logistic regression was performed comparing the group that required a reactive feeding tube insertion to those who did not require any feeding tube insertion to identify risk factors. Results: A total of 350 patients were included in the study, and 132/350 (38%) patients received a feeding tube. 50 out of 132 (38%) patients had feeding tube inserted reactively. Severe dysphagia (OR 19.9, p < 0.001) at diagnosis and decision to undergo chemotherapy (OR 2.8, p = 0.008) appeared to be predictors for reactive feeding tube insertion. The reactive insertion group had a 7% higher rate of complications relating to feeding tube. Conclusion: Severe dysphagia at diagnosis and undergoing chemotherapy were identified as risk factors for requiring a feeding tube. Ultimately, the aim is to create a predictive tool that utilizes these risks factors to accurate identify high-risk patients who may benefit from prophylactic feeding tube insertion.

An evaluation of nasogastric (NG) tube removal practices and nutritional intake parameters in an acute neurosurgical population: The development of an NG Transition Feeding Protocol.

BACKGROUND: As a result of the complex nature of neurosurgical patients, nasogastric (NG) tube feeding is often implemented for patients who are unable to consume adequate oral intake. During recovery, patients on enteral nutrition (EN) are progressed to oral nutrition, which can result in NGT removal and discontinuation of supportive feeding plans. This is often before patients become established on sufficient oral intake to meet their nutritional requirements. METHODS: We conducted an exploration of current NG removal practices in patients (n = 23) across five neurosurgical wards over a 3-month period to assess practitioner review response times, NG feeding duration, decision making on NG removal, and the influence of dietary recommendations and differing EN protocols on patients' ability to meet their nutritional requirements. Our aim was to use this data to design and implement a protocol to improve consistency of these practices. RESULTS: After oral intake was commenced, only those receiving supplementary EN achieved nutritional targets immediately. Conversely, no patient who had their NGT removed at this stage achieved these targets. Following NG removal, the likelihood of a patient meeting nutritional targets was influenced by the decision maker, supporting the practice of registered dietitian led cessation of NG feeding. These findings led us to develop an "NG Transition Feeding Protocol" to serve as a simple, clear pathway which treating teams can utilise to guide NG feeding decisions. CONCLUSIONS: NG feeding supports neurosurgical patients to meet nutritional requirements in the early stages following commencement of oral intake. The development of an "NG Transition Feeding Protocol" may help to improve consistency of transition feeding on neurosurgical wards, allowing time for nutrition assessment to support informed decisions around NG removal. The aim of this protocol is to improve the efficiency of transition feeding, improve dietetic workload efficiency, nursing staff confidence and avoid compromising nutritional status of patients as a result of the early cessation of EN.
