Feeding tube use and complications in Prader-Willi syndrome: Data from the Global Prader-Willi Syndrome Registry.

Guidance on indications for, and types of, feeding tubes recommended in Prader-Willi syndrome (PWS) is needed. A Global PWS Registry survey was developed to investigate nasogastric (NG) and gastrostomy (G) tube use and associated complications. Of 346 participants, 242 (69.9%) had NG-tubes, 17 (4.9%) had G-tubes, and 87 (25.1%) had both NG- and G-tubes. Primary indication for placement was "feeding difficulties and/or poor weight gain" for both NG- (90.2%) and G-tubes (71.2%), while "aspiration/breathing difficulties" was the procedural indication for 6.4% of NG-tubes and 23.1% of G-tubes. NG-tubes were generally removed by age 6 months (NG Only: 82.9%; NG/G: 98.8%), while G-tubes were often removed by age 2 years (G Only: 85.7%; NG/G: 70.5%). The severe complication rate from G-tubes was 31.7% and from NG-tubes was 1.2%. Overall, caregivers indicated the presence of an NG- or G-tube had a positive effect on quality of life. Feeding difficulties in PWS are largely managed by NG-tube alone. The severe complication rate from G-tubes was about 25 times higher than from NG-tubes; yet, G-tube placement rates have generally increased. G-tube placement puts individuals with PWS at risk for anesthesia and surgery-related complications and should be considered judiciously by a multidisciplinary team.

Characteristics of older adults receiving enteral feeding at a geriatric medical center.

BACKGROUND: Malnutrition is a prevalent and hard-to-treat condition in older adults. enteral feeding is common in acute and long-term care. Data regarding the prognosis of patients receiving enteral feeding in geriatric medical settings is lacking. Such data is important for decision-making and preliminary instructions for patients, caregivers, and physicians. This study aimed to evaluate the prognosis and risk factors for mortality among older adults admitted to a geriatric medical center receiving or starting enteral nutrition (EN). METHODS: A cohort retrospective study, conducted from 2019 to 2021. Patients admitted to our geriatric medical center who received EN were included. Data was collected from electronic medical records including demographic, clinical, and blood tests, duration of enteral feeding, Norton scale, and Short Nutritional Assessment Questionnaire score. Mortality was assessed during and after hospitalization. Data were compared between survivors and non-survivors. Multivariate logistic regressions were performed to identify the variables most significantly associated with in-hospital mortality. RESULTS: Of 9169 patients admitted, 124 (1.35%) received enteral feeding tubes. More than half of the patients (50.8%) had polypharmacy (over 8 medications), 62% suffered from more than 10 chronic illnesses and the majority of patients (122/124) had a Norton scale under 14. Most of the patients had a nasogastric tube (NGT) (95/124) and 29 had percutaneous endoscopic gastrostomies (PEGs). Ninety patients (72%) died during the trial period with a median follow-up of 12.7 months (0.1-62.9 months) and one-year mortality was 16% (20/124). Associations to mortality were found for marital status, oxygen use, and Red Cell Distribution Width (RDW). Age and poly-morbidity were not associated with mortality. CONCLUSION: In patients receiving EN at a geriatric medical center mortality was lower than in a general hospital. The prognosis remained grim with high mortality rates and low quality of life. This data should aid decision-making and promote preliminary instructions.

Prognostic Factors Associated with Post-Stroke Dysphagia in Intracerebral Hemorrhage Patients.

Spontaneous intracerebral hemorrhage (ICH) constitutes a significant portion of acute stroke incidents worldwide, often leading to post-stroke dysphagia (PSD), affecting 50-77% of survivors and worsening patient morbidity. This study aimed to identify predictive variables for PSD among patients with spontaneous ICH. A retrospective cohort study was conducted on adult patients with acute spontaneous ICH, confirmed by brain computed tomography, from June 2019 to June 2023. We analyzed demographic, neuroimaging, and stroke-specific characteristics and rehabilitation indicators. PSD was evaluated using nasogastric (NG) tube retention and the Functional Oral Intake Scale (FOIS) levels at 4 and 12 weeks post-ICH. Statistical analyses involved univariate and multivariate logistic regression to identify PSD predictors. A total of 310 ICH patients were included in the study. At 4 weeks, significant predictors for NG tube retention included 24-hour National Institute of Health Stroke Scale (NIHSS) scores, estimated glomerular filtration rate and sitting balance. At 12 weeks, hospital stay duration and ICH score were significant predictors for NG tube retention. Regarding the FOIS, significant predictors at 4 weeks included higher 24-hour NIHSS scores, compromised sitting balance, immobility-related complications, initial hematoma volume and intraventricular hemorrhages. At 12 weeks, older age and higher 24-hour NIHSS scores significantly predicted lower FOIS levels. Our findings demonstrate that PSD in ICH patients is influenced by a complex interplay of factors, including stroke severity, renal function, and physical impairment. The study highlights the importance of early neurological assessment, physical function, and comprehensive management in improving swallowing outcomes, emphasizing a multifaceted approach to enhancing outcomes for ICH survivors.

The effect of evidence-based skin care and hydrocolloid dressing in the prevention of nasogastric tube-related pressure injury: A randomized controlled clinical trial.

OBJECTIVE: The aim of this study is to determine the effect of evidence-based skin care and hydrocolloid dressing in the prevention of nasogastric (NG) tube-related pressure injuries (PIs). DESIGN: This study was a three-arm parallel-group randomized controlled clinical trial registered on Clinicaltrials.gov (NCT04682925). METHODS: The study was conducted with 102 patients who underwent NG tube insertion immediately after admission to the anesthesiology and reanimation intensive care unit of a university hospital in Turkey. Patients were randomly assigned to three groups: a control arm (n = 34), a hydrocolloid dressing arm (n = 34), and a skin care arm (n = 34). Patients in the hydrocolloid dressing arm received daily application of hydrocolloid dressing to the nasal mucosa and alae nasi where the NG tube was inserted. Patients in the skin care arm received skin care interventions in preventing PIs twice daily. No interventions were administered to the control group. RESULTS: No NG tube-related PIs occurred in any patients in the hydrocolloid dressing arm. However, PIs occurred in 97.1 % of patients in the control arm and 94.1 % of patients in the skin care arm. According to the results of regression analysis, failure to apply hydrocolloid dressing increased the risk of NG tube-related PIs by 20.3 times [OR = 20.301, 95 % CI = 6.335-65.053, p < 0.001]. Additionally, a one-unit increase in the duration of ventilation days reduced the risk of NG tube-related PIs by 17.7 % (1-0.823) [OR = 0.823 (95 % CI = 0.684-0.989), p = 0.038]. CONCLUSION: Results revealed that hydrocolloid dressing is effective in preventing of NG tube-related PIs, whereas skin care did not demonstrate the same effectiveness.

Complicated placement of a nasogastric tube in the gastric mucosa: A case report and literature review.

Nasogastric tubes (NGTs) are commonly used in the intensive care unit (ICU) and are often inserted blindly at the bedside. Previous studies have highlighted various complications associated with NGT misplacement, including epistaxis, pneumothorax and even fatal perforations. To reduce the incidence of complications, guidelines recommend confirming the correct position of the NGT through radiography, pH testing, end-expiratory carbon dioxide monitoring, ultrasonography, etc. Herein, we present the case of a 78-year-old man who experienced sudden dyspnoea, was brought to the ICU and subsequently developed gastrointestinal bleeding following improper NGT placement. In this patient, air was rapidly injected down the NGT while auscultating for a 'whooshing sound' over the epigastrium. However, the correct position of the NGT was eventually confirmed by X-ray. Urgent upper gastrointestinal endoscopy revealed an oesophagogastric submucosal tunnelling of the NGT. This case emphasizes that auscultation may be unreliable and no longer encouraged. Additionally, various verification methods may not detect such rare complications related to NGT placement, making it necessary to focus on the emerging clinical manifestations following NGT insertion. Moreover, gaining further insight into the history of gastrointestinal diseases in patients may be beneficial. RELEVANCE TO CLINICAL PRACTICE: This case underscores the importance of noting resistance during a blind nasogastric tube (NGT) insertion in the intensive care unit (ICU). Additionally, the 'whooshing testing' for tube placement verification is not recommended. Although radiographic confirmation remains the gold standard, it may not effectively identify rare complications. Furthermore, emerging clinical signs (such as the abnormal nature of the gastrointestinal decompression drainage fluid, hypotension and anaemia) after insertion may suggest NGT misalignment. Finally, in urgent ICU settings, the patient's history of gastrointestinal disease should not be overlooked, as it can lead to complications such as gastrointestinal bleeding.

[Critical care nurses' decision-making regarding verification of blindly inserted gastric tubes: A cross-sectional questionnaire study]. / Entscheidungsfindung von Intensivpflegefachpersonen zur Verifikation blind applizierter Magensonden.

Critical care nurses' decision-making regarding verification of blindly inserted gastric tubes: A cross-sectional questionnaire study Abstract: Background: The placement and verification of the correct position of blindly applied gastric tubes is regularly performed by nurses in clinical practice. International guidelines recommend a radiological verification as a "first-line" method or if pH measurement is not possible. For Germany, neither evidence-based recommendations nor current data are available. Question: Which methods are used by nurses in German intensive care units for verification of the correct position of blindly applied gastric tubes and how do they assess the reliability of different methods? Methods: Multicenter questionnaire survey. Intensive care units in a non-probability, citeria-based sampling of hospitals in and around Cologne, Germany were included. One nurse was included per participating ward. Analyses were mostly descriptive. Results: In 22 hospitals, 38 wards agreed to participate and 32 (84%) responded to the survey. Auscultation of the upper abdomen with simultaneous air insufflation and aspiration of gastric secretions are frequently used methods for determining the position of gastric tubes. Participants consider auscultation, aspiration of gastric secretions, and radiological control as reliable methods. Conclusions: The findings are in contrast to international recommendations and support the need for evidence-based best practice recommendations and training. Likewise, there is a need for research on feasible bedside methods.

Nasogastric tube insertion length measurement and tip verification in adults: a narrative review.

Nasogastric feeding tube insertion is a common but invasive procedure most often blindly placed by nurses in acute and chronic care settings. Although usually not harmful, serious and fatal complications with misplacement still occur and variation in practice still exists. These tubes can be used for drainage or administration of fluids, drugs and/or enteral feeding. During blind insertion, it is important to achieve correct tip position of the tube ideally reaching the body of the stomach. If the insertion length is too short, the tip and/or distal side-openings at the end of the tube can be located in the esophagus increasing the risk of aspiration (pneumonia). Conversely, when the insertion length is too long, the tube might kink in the stomach, curl upwards into the esophagus or enter the duodenum. Studies have demonstrated that the most frequently used technique to determine insertion length (the nose-earlobe-xiphoid method) is too short a distance; new safer methods should be used and further more robust evidence is needed. After blind placement, verifying correct gastric tip positioning is of major importance to avoid serious and sometimes lethal complications.

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.

Nasogastric tube feeding improves nutritional status and physical state in esophageal cancer patients during chemoradiotherapy: a retrospective study.

OBJECTIVE: To compare the complication rates, nutritional status, and physical state between esophageal cancer (EC) patients managed by nasogastric tube (NGT) feeding versus those managed by oral nutritional supplementation (ONS) during chemoradiotherapy. METHODS: EC patients undergoing chemoradiotherapy managed by nonintravenous nutritional support in our institute were retrospectively recruited and divided into an NGT group and an ONS group based on the nutritional support method. The main outcomes, including complications, nutritional status, and physical state, were compared between groups. RESULTS: The baseline characteristics of EC patients were comparable. There were no significant differences in the incidence of treatment interruption (13.04% vs. 14.71%, P = 0.82), death (2.17% vs. 0.00%, P = 0.84), or esophageal fistula (2.17% vs. 1.47%, P = 1.00) between the NGT group and ONS group. Body weight loss and decrease in albumin level were significantly lower in the NGT group than in the ONS group (both P < 0.05). EC patients in the NGT group had significantly lower Nutritional Risk Screening 2002 (NRS2002) and Patient-Generated Subjective Global Assessment (PG-SGA) scores and significantly higher Karnofsky Performance Status (KPS) scores than patients in the ONS group (all P < 0.05). The rates of grade > 2 esophagitis (10.00% vs. 27.59%, P = 0.03) and grade > 2 bone marrow suppression (10.00% vs. 32.76%, P = 0.01) were significantly lower in the NGT group than in the ONS group. There were no significant differences in the incidence of infection and upper gastrointestinal disorders or therapeutic efficacy between groups (all P > 0.05). CONCLUSIONS: EN through NGT feeding leads to significantly better nutritional status and physical state in EC patients during chemoradiotherapy than EN via ONS. NGT may also prevent myelosuppression and esophagitis..

Routine nasogastric tube placement after gastric endoscopic full-thickness resection of tumor size ≤ 2 cm may be unnecessary: a propensity score-matching analysis.

BACKGROUND: Endoscopic full-thickness resection is a common endoscopic procedure for treating gastrointestinal submucosal tumors. Nasogastric tube placement is frequently performed after abdominal surgery, but the routine use of this approach remains controversial. The aim of this research was to explore whether nasogastric tube placement after gastric endoscopic full-thickness resection is necessary. METHODS: A retrospective study enrolled patients who underwent gastric endoscopic full-thickness resection in our hospital between January 2014 and January 2019, and all the patients had a tumor size ≤ 2 cm. The patients were divided into two groups according to whether a nasogastric tube was placed. Postprocedural adverse events and hospital stay duration were compared between the two groups using 1:1 propensity score matching. RESULTS: A total of 461 patients were enrolled in this study, including 385 patients in the nasogastric tube group (NGT group) and 76 patients in the non-nasogastric tube group (non-NGT group). After matching, the baseline characteristics of 73 patients in the NGT group and 73 patients in the non-NGT group were balanced (p > 0.05). The postprocedural fever rate in the NGT group was significantly higher than that in the non-NGT group (23.3% vs. 9.6%, p = 0.044). 6.9% (5/73) of patients experienced severe nasogastric tube-related throat discomfort. However, the duration of hospitalization stay was not different between the two groups. CONCLUSIONS: For patients with tumor size ≤ 2 cm, routine nasogastric tube placement after gastric endoscopic full-thickness resection may be unnecessary.

Effectiveness of Lidocaine nasal drops versus placebo drops for reducing the discomfort of nasogastric tube insertion: a randomized controlled trial study.

PURPOSE: Nasogastric tube (NGT) insertion can be painful and distressing for the patient. Lidocaine nasal drops might be effective as a local anesthetic agent before the procedure. This study aimed to compare the effects of Lidocaine nasal drops versus placebo drops for reducing the discomfort of this procedure. METHODS: Patients indicated for NGT insertion were categorized into two groups randomly. The Lidocaine group had 2% Lidocaine instilled nasally 3 min before the procedure and the control group had normal saline drops instilled. We compared the pain scores (using a visual analog scale) and complications between the two groups. RESULTS: A total of 126 patients who required NGT insertion between September, 2021 and August, 2022 were enrolled in this study. The pain score of the Lidocaine nasal drops group was 1.41 ± 0.50 (range 1-2) and that of the control group was 4.54 ± 1.03 (range 3-7) (p < 0.01). The duration of the procedure in the Lidocaine and control groups was 1.52 ± 0.76 min and 3.38 ± 1.36 min, respectively (p < 0.01). The insertion was completed successfully within the first attempt in 98% of the Lidocaine group patients, whereas two or three attempts were needed in the control group. The incidence of complications such as vomiting, coughing, difficult breathing, and aspiration was lower in the Lidocaine group than in the control group (p < 0.01). CONCLUSION: Instilling Lidocaine nasal drops before NGT insertion alleviated discomfort and reduced procedure-associated complications.

Efficacy of a gastric tube insertion guide for insertion of a nasogastric tube: a prospective, randomized controlled clinical study.

PURPOSE: We studied whether a newly available gastric tube insertion guide (Fuji Medical, Tokyo, Japan) was effective in insertion of a nasogastric tube. METHODS: Sixty anesthetized patients were randomly allocated to three groups, and we attempted to insert a nasogastric tube with a blind technique (Group B), with the lateral neck pressure (Group L), or with the tube guide (Group G). If the insertion failed in Group B or L, its insertion was attempted with the tube guide. Primary outcome measure was the insertion success rate within 300 s. RESULTS: The success rate in Group G (19 of 20 patients) was significantly higher than Group L (13 of 20 patients) (P = 0.04; 95% confidence intervals for difference: 16-44%), and than Group B (11 of 19 patients) (P = 0.008; 23-50%). In the 15 patients of Groups B and L, in whom insertion had failed, insertion with the tube guide was successful in 14 patients. There was no significant difference in insertion time between the groups, but in patients in whom insertion was successful, it was significantly longer in Group G (median of 147 s) than in Group L (66 s) (P < 0.01) and Group B (46 s) (P < 0.01). Minor complications occurred in 2 patients in Group B, 1 in Group L, and 5 in Group G (P > 0.05). CONCLUSION: We conclude that the gastric tube insertion guide (Fuji Medical, Tokyo, Japan) may be useful when the conventional method of insertion has failed.

Predictive Factors for Nasogastric Tube Removal in Post-Stroke Patients.

Background and Objectives: Stroke patients have different levels of functional impairment, and rehabilitation is essential to achieving functional recovery. Many post-stroke patients transition from acute treatment to post-acute care (PAC) with nasogastric tubes (NGTs) for rehabilitation. However, long-term NGT placement can lead to several complications, and its earlier removal can effectively reduce the incidence of mortality. This study aimed to use a PAC-cerebrovascular disease (CVD) program and physical functional evaluation scale tools to demonstrate the factors associated with NGT removal before post-stroke patient discharge. Materials and Methods: In this retrospective cohort study, data were collected between January 2017 and August 2022. We divided patients who had NGTs at admission into discharged with and without NGT groups to compare their baseline characteristics and physical functional status. Logistic regression analysis was used to detect the predictive factors for NGT removal. Results: There were 63 participants: 22 without NGT removal and 41 with NGT removal. The NGT removal rate was 65%. Age and scores for the activities of daily living by the Barthel index (BI), Functional Oral Intake Scale (FOIS), Mini-Mental State Examination, and Concise Chinese Aphasia Test were significantly different in terms of NGT removal status, but only the BI and FOIS were significantly correlated with NGT removal. Patients' BI scores indicating severe to moderate dependence (21-90) had a 4.55 times greater chance of NGT removal (odds ratio, 4.55; p < 0.05) than patients who had total dependence (<20). Every one-point increase in FOIS score indicated a 3.07 times greater chance of NGT removal (odds ratio, 3.07; p < 0.05). Conclusions: The BI and FOIS evaluations may indicate the probability of NGT removal in patients.

Prevention of microbial colonization of feeding tubes in the intensive care unit.

BACKGROUND: Various microorganisms which increase the mortality rate in the intensive care unit (ICU) cause microbial colonization of the nasogastric tube (NGT) and use the NGT as a reservoir. AIM: To detect the colonization on the NGT and to determine the effect that training regarding hand hygiene, NGT management, and enteral feeding (EF) provided to ICU nurses and auxiliary service staff (ASS) has on the level of NGT colonization. STUDY DESIGN: A quasi-experimental pre-test and post-test control design was used in this study. Microbial samples were taken from the outer and inner parts of NGT. The microorganisms were categorized as: group 1, no risk; group 2, low risk pathogenic; group 3, high-risk pathogenic group. The training was given to nurses (n = 15) and ASS (n = 7). Hand hygiene, NGT, and EF care training are provided to nurses and ASS by researchers. A total of three training sessions were scheduled to be held in 3 weeks so that all health care staff members were trained. Each session lasted 2 h in total. Patients were assigned to a group if one of the microorganisms presented on the outer surface of the patient's feeding tube and/or on the hub. The hand hygiene compliance was evaluated by direct observation according to the World Health Organization hand hygiene indications. RESULTS: The study was conducted with 46 patients. Evaluating the patients for the presence of microorganisms before education revealed that 4.3% were in group 1, 21.8% were in group 2, and 73.9% were in group 3. After the education, evaluating the samples for the presence of microorganisms revealed that 39.1% were in group 1, 13% were in group 2, and 47.8% were in group 3. A statistically significant difference was found between the number of samples included in the groups after the participants had received training (H = 8.186; p = .017). CONCLUSIONS: An NGT could act as a reservoir of microbial colonization and high-risk microorganisms could be on the tube. Providing training not only to nurses but also to ASS will help reduce the risk of colonization. RELEVANCE TO CLINICAL PRACTICE: Eliminating such colonization with effective hand hygiene during NGT feeding is a cost-effective method. Providing training not only to nurses but also to ASS will help obtain the optimum benefit from patient care.

[Preparation and Performance Evaluation of Polyacrylamide Hydrogel Coating on the Surface of Silicone Rubber Nasogastric Tube].

Objective: To prepare the hydrogel coating on the surfaces of nasogastric tubes and to evaluate its effect on the insertion of nasogastric tubes in a rabbit model. Methods: The polyacrylamide (PAAm) hydrogel coating was prepared by UV-induced free radical polymerization. The morphology of the PAAm coating and its interfacial bonding with the silicone rubber substrates of nasogastric tubes were observed with scanning electron microscope. The composition of the coating was analyzed by Fourier transform infrared (FTIR) spectrometer and X-ray photoelectron spectrometer (XPS). The water absorption power and stability of the coating were measured by the weighing method. Water contact angle meter was used to measure the wettability of the coating and tribometer was used to determine the friction coefficient of the silicone rubber substrates before and after the modification. The cytotoxicity of the coating on L929 murine fibroblast cell line was explored with CCK-8 assay after 24-h coculturing of the L929 cell line with silicone rubber substrates before and after modification. An animal model of nasogastric tube insertion in New Zealand rabbits was used to evaluate the effect of the lubrication coating by assessing the insertion time and nasal damage. Results: In this study, PAAm hydrogel coating was prepared and constructed on the surface of silicone rubber nasogastric tubes. The coating, with a three-dimensional network structure, showed strong interfacial bonding with silicone rubber substrates. The appearance of amino and carbonyl groups indicated that the PAAm hydrogel coating was grafted on the surfaces of nasogastric tubes. Before the modification, the silicone rubber substrate essentially did not absorb much water, whereas, after the modification, the silicone rubber substrate showed significant improvement of as much as 2.9% in water absorption. After sonication for 90 min, the weight loss rate was only 0.15%. Compared with pristine nasogastric tubes, the water contact angle of the modified nasogastric tubes was reduced from 111.9°±2.2° to 58.9°±1.5° ( t=22.59, P<0.05). In addition, the friction coefficient of silicone rubber nasogastric tubes decreased by 69.3% from 0.378±0.05 to 0.116±0.004 ( t=42.80, P<0.05) after modification. Moreover, there was no significant difference in the cytocompatibility between L929 cells cocultured with pristine nasogastric tube and those cocultured with modified nasogastric tube. The animal experiment of nasogastric tube insertion showed that the insertion time of the modified nasogastric tubes was reduced from (41.6±7.8) s to (12.4±2.9) s ( t=8.509, P<0.05). Laryngoscopy revealed that the PAAm hydrogel coating significantly reduced the mucosal damage caused by the insertion of nasogastric tubes. Conclusion: In this study, PAAm hydrogel coating with strong interfacial bonding was prepared on the surface of silicone rubber nasogastric tubes. The coating has excellent hydrophilic lubrication property and cytocompatibility, effectively shortens the insertion time, and reduces the damage caused by nasogastric tube insertion.

Rates and Determinants of Home Nasogastric Tube Feeding in Infants Born Very Preterm.

OBJECTIVE: To examine rates and determinants of home nasogastric (NG)-tube feeding at hospital discharge in a cohort of very preterm infants within the Canadian Neonatal Network (CNN). STUDY DESIGN: This was a population-based cohort study of infants born <33 weeks of gestation and admitted to neonatal intensive care units (NICUs) participating in the CNN between January 1, 2010, and December 31, 2018. We excluded infants who had major congenital anomalies, required gastrostomy-tube, or were discharged to non-CNN facilities. Multivariable logistic regression analysis was used to identify independent determinants of home NG-tube feeding at hospital discharge. RESULTS: Among the 13 232 infants born very preterm during the study period, 333 (2.5%) were discharged home to receive NG-tube feeding. Rates of home NG-tube feeding varied across Canadian NICUs, from 0% to 12%. Determinants of home NG-tube feeding were gestational age (aOR 0.94 per each gestational week increase, 95% CI 0.88-0.99); duration of mechanical ventilation (aOR 1.02 per each day increase, 95% CI 1.01-1.02); high illness severity at birth (aOR 1.32, 95% CI 1.01-1.74); small for gestational age (aOR 2.06, 95% CI 1.52-2.78); male sex (aOR 0.61, 95% CI 0.49-0.77); severe brain injury (aOR 1.60, 95% CI 1.10-2.32); and bronchopulmonary dysplasia (aOR 2.22, 95% CI 1.67-2.94). CONCLUSIONS: Rates of home NG-tube feeding varied widely between Canadian NICUs. Higher gestational age and male sex reduced the odds of discharge home to receive NG-tube feeding; and in contrast small for gestational age, severe brain injury, prolonged duration on mechanical ventilation and bronchopulmonary dysplasia increased the odds.

Are Differences in Dysphagia Assessment, Oral Care Provision, or Nasogastric Tube Insertion Associated with Stroke-Associated Pneumonia? A Nationwide Survey Linked to National Stroke Registry Data.

INTRODUCTION: Stroke-associated pneumonia (SAP) is a common complication associated with poor outcomes. Early dysphagia screening and specialist assessment is associated with a reduced risk of SAP. Evidence about oral care and nasogastric tube (NGT) placement is equivocal. This study aimed to expose variations in dysphagia management practices and explore their associations with SAP. PARTICIPANTS AND METHODS: Speech pathologists from 166 stroke units in England and Wales were surveyed about dysphagia assessment and management, oral care, and NGT placement. Survey data were then linked to the Sentinel Stroke National Audit Programme (SSNAP), the national register of stroke. Univariable and multivariable linear regression models were fitted to estimate the association between dysphagia management practices and SAP incidence. RESULTS: 113 hospitals completed the survey (68%). Variation was evident in dysphagia screening protocols (DSPs), oral care, and NGT practice while specialist swallow assessment data patterns were more consistent. Multivariable analysis showed no evidence of an association in incidence of SAP when using a water-only hospital DSP compared to a multiconsistency DSP (B -0.688, 95% CI: -2.912 to 1.536), when using written swallow assessment guidelines compared to not using written guidelines (B 0.671, 95% CI: -1.567 to 2.908), when teams inserted NGTs overnight compared to teams which did not (B -0.505, 95% CI: -2.759 to 1.749), and when teams had a written oral care protocol compared to those which did not (B -1.339, 95% CI: -3.551 to 0.873). DISCUSSION AND CONCLUSION: Variation exists in dysphagia screening and management, but there was no evidence of an association between clinical practice patterns and incidence of SAP. Further research with larger sample sizes is needed to examine association with SAP.

Long-term outcomes of nasogastric tube with Gastrografin for adhesive small bowel obstruction.

BACKGROUND: We had previously reported that the administration of Gastrografin through a nasogastric tube (NGT-G) followed by long tube (LT) strategy could be a novel standard treatment for adhesive small bowel obstruction (ASBO); however, the long-term outcomes after initial improvement remain unknown. This study aimed to analyze the long-term outcomes of first-line NGT-G. METHODS: Enrolled patients with ASBO were randomly assigned to receive LT or NGT-G between July 2016 and November 2018. Thereafter, the cumulative surgery rate, cumulative recurrence rate, and overall survival (OS) rate were analyzed. In addition, subset analysis was conducted to determine the cumulative recurrence rate according to colonic contrast with Gastrografin at 24 h. RESULTS: A total of 223 patients (LT group, n = 111; NGT-G group, n = 112) were analyzed over a median follow-up duration of 550 days. The cumulative 1-year surgery rates, cumulative 1-year recurrence rates, and 1-year OS rates in the LT and NGT-G groups were 18.8% and 18.1%, 30.0% and 31.7%, and 99.1% and 96.6%, respectively; no significant differences were observed between both groups. In the NGT-G group, a negative colonic contrast at 24 h demonstrated a higher tendency for future recurrence compared with a positive colonic contrast at 24 h (1-year recurrence rate: negative contrast, 46.9% vs positive contrast, 27.6%). CONCLUSIONS: Gastrografin through a nasogastric tube followed by LT can be a promising treatment strategy for ASBO, with long-term efficacies equivalent to initial LT placement.

Pre-emptive active drainage of reflux (PARD) in Ivor-Lewis oesophagectomy with negative pressure and simultaneous enteral nutrition using a double-lumen open-pore film drain (dOFD).

BACKGROUND: Postoperative reflux can compromise anastomotic healing after Ivor-Lewis oesophagectomy (ILE). We report on Pre-emptive Active Reflux Drainage (PARD) using a new double-lumen open-pore film drain (dOFD) with negative pressure to protect the anastomosis. METHODS: To prepare a dOFD, the gastric channel of a triluminal tube (Freka®Trelumina, Fresenius) is coated with a double-layered open-pore film (Suprasorb®CNP drainage film, Lohmann & Rauscher) over 25 cm. The ventilation channel is blocked. The filmcoated segment is placed in the stomach and the intestinal feeding tube in the duodenum. Negative pressure is applied with an electronic vacuum pump (- 125 mmHg, continuous suction) to the gastric channel. Depending on the findings in the endoscopic control, PARD will either be continued or terminated. RESULTS: PARD was used in 24 patients with ILE and started intraoperatively. Healing was observed in all the anastomoses. The median duration of PARD was 8 days (range 4-21). In 10 of 24 patients (40%) there were issues with anastomotic healing which we defined as "at-risk anastomosis". No additional endoscopic procedures or surgical revisions to the anastomoses were required. CONCLUSIONS: PARD with dOFD contributes to the protection of anastomosis after ILE. Negative pressure applied to the dOFD (a nasogastric tube) enables enteral nutrition to be delivered simultaneously with permanent evacuation and decompression.

Liquid Enteral Nutrients Alter the Pharmacokinetics of Orally Administered Carbamazepine in Rats.

The interaction between enteral nutrients (ENs) and drugs co-administered through a nasogastric (NG) tube reportedly affects the absorption and resultant plasma concentrations of the respective drugs. However, the gastrointestinal absorption of carbamazepine (CBZ), an antiepileptic drug, co-administered with liquid ENs through an NG tube has not been clarified. In this study, we measured the recovery rate (%) of CBZ (Tegretol® powder) passed through an NG tube when co-administered with distilled water or ENs (F2α®, Racol® NF, Ensure Liquid®, and Renalen® LP) of different compositions, frequently used in Japan. We also measured the plasma CBZ level in 26 rats after oral co-administration of CBZ with liquid ENs. The CBZ recovery rate was close to 100% in rats of all EN groups after passage through the NG tube. Furthermore, CBZ area under the plasma concentration-time curve from time zero to 9 h (AUC0→9h) of the Ensure liquid® group decreased compared with that of control group (P < 0.05) and Renalen® LP group (P < 0.01). However, the AUC0→9h of CBZ remained unchanged when co-administered with Ensure liquid® 2 h after initial CBZ administration. In conclusion, the co-administration of CBZ with Ensure Liquid® caused a reduction in the absorption of CBZ from the gastrointestinal tract, without adsorption on the NG tube. The administration of Ensure Liquid® 2 h after CBZ is a way to prevent a decrease in plasma CBZ concentration. Our findings suggest that carefully monitoring the plasma levels of CBZ is necessary in co-administation with Ensure liquid® to prevent the unintended effects of the interaction between CBZ and liquid EN.
