Disparate Response to Metoclopramide Therapy for Gastric Feeding Intolerance in Trauma Patients With and Without Traumatic Brain Injury

Patients with traumatic brain injury (TBI) have delayed gastric emptying and often require prokinetic drug therapy to improve enteral feeding tolerance. The authors hypothesized that metoclopramide was less efficacious for improving gastric feeding tolerance for trauma patients with TBI compared to trauma patients without TBI. A retrospective analysis was conducted of patients admitted to the trauma or neurosurgical intensive care unit who received gastric feeding from January 2006 to April 2008. Gastric feeding intolerance was defined by a gastric residual volume >200 mL or emesis with abdominal distension or discomfort. Patients with gastric feeding intolerance were given metoclopramide 10 mg intravenously every 6 hours, followed by a dose escalation to 20 mg, and then combination therapy with metoclopramide and erythromycin 250 mg intravenously every 6 hours if intolerance persisted. In total, 882 trauma patients (49% with TBI) were evaluated. TBI patients had a higher incidence of gastric feeding intolerance than those without TBI (18.6% vs 10.4%, P ≤ .001). Efficacy rates for metoclopramide 10 mg, metoclopramide 20 mg, and metoclopramide‐erythromycin were 55%, 62%, and 79%, respectively (P ≤ .03). Metoclopramide failure occurred in 54% of patients with TBI compared to 35% of patients without TBI, respectively (P ≤ .02), due to a greater prevalence of tachyphylaxis. Single‐drug therapy with metoclopramide was less effective for TBI trauma patients compared to trauma patients without TBI. Combination therapy with erythromycin as first‐line therapy for TBI trauma patients with gastric feeding intolerance is indicated if there are no contraindications or significant drug interactions.     

Quality of Life in a Randomized Trial of Nasogastric Tube Feeding in Acute Pancreatitis

Background: Recent clinical studies have shown that nasogastric tube feeding is safe in the majority of patients with acute pancreatitis. Patient‐reported outcomes are important, but the impact of nasogastric tube feeding on the quality of life has not been investigated. This study aims to compare quality of life between nasogastric tube feeding and nil‐by‐mouth groups during and after hospitalization. Methods: Patient‐reported outcomes were recorded daily in a patient diary during hospitalization. The Abdominal Surgery Impact Scale questionnaire was used to determine patients' quality of life. The patients were then followed up at 1 week and 1, 3, and 6 months after discharge. Results: While 17 patients were randomized to nasogastric tube feeding, 18 were put on nil‐by‐mouth. The overall quality of life and individual domains did not differ significantly between the groups during hospitalization (P = .500) or follow‐up. For the entire cohort, individual quality‐of‐life domains during hospitalization improved significantly, including functional impairment (P < .001), pain (P < .001), sleep (P = .035), and psychological function (P < .001). Quality of life further improved for all patients from time of hospital discharge to 3 (P = .002) and 6 months follow‐up (P < .001) but not to 1 week and 1 month. Conclusions: The use of nasogastric tube feeding, in comparison with nil‐by‐mouth, does not impair patients' quality of life. Given the clinical benefits of nasogastric tube feeding, nasogastric feeding should be considered the first‐line approach in all acute pancreatitis patients requiring enteral nutrition.     

Outcomes of Infants With Home Tube Feeding: Comparing Nasogastric vs Gastrostomy Tubes

Background: The aim of this study was to determine the tube‐related complications and feeding outcomes of infants discharged home from the neonatal intensive care unit (NICU) with nasogastric (NG) tube feeding or gastrostomy (G‐tube) feeding. Materials and Methods: We performed a chart review of 335 infants discharged from our NICU with home NG tube or G‐tube feeding between January 2009 and December 2013. The primary outcome was the incidence of feeding tube–related complications requiring emergency department (ED) visits, hospitalizations, or deaths. Secondary outcome was feeding status at 6 months postdischarge. Univariate and multivariate analyses were conducted. Results: There were 322 infants discharged with home enteral tube feeding (NG tube, n = 84; G‐tube, n = 238), with available outpatient data for the 6‐month postdischarge period. A total of 115 ED visits, 28 hospitalizations, and 2 deaths were due to a tube‐related complication. The incidence of tube‐related complications requiring an ED visit was significantly higher in the G‐tube group compared with the NG tube group (33.6% vs 9.5%, P < .001). Two patients died due to a G‐tube–related complication. By 6 months postdischarge, full oral feeding was achieved in 71.4% of infants in the NG tube group compared with 19.3% in the G‐tube group (P < .001). Type of feeding tube and percentage of oral feeding at discharge were significantly associated with continued tube feeding at 6 months postdischarge. Conclusion: Home NG tube feeding is associated with fewer ED visits for tube‐related complications compared with home G‐tube feeding. Some infants could benefit from a trial home NG tube feeding.     

Nutritional factors associated with survival following enteral tube feeding in patients with motor neurone disease

Background:  Motor neurone disease (MND) is a progressive neurodegenerative disease leading to limb weakness, wasting and respiratory failure. Prolonged poor nutritional intake causes fatigue, weight loss and malnutrition. Consequently, disease progression requires decisions to be made regarding enteral tube feeding. The present study aimed to investigate the survival, nutritional status and complications in patients with MND treated with enteral tube feeding. Methods:  A retrospective case note review was performed to identify patients diagnosed with MND who were treated with enteral tube feeding. A total of 159 consecutive cases were identified suitable for analysis. Patients were treated with percutaneous endoscopic gastrostomy (PEG), radiologically inserted gastrostomy (RIG) or nasogastric feeding tube (NGT). Nutritional status was assessed by body mass index (BMI) and % weight loss (% WL). Serious complications arising from tube insertion and prescribed daily energy intake were both recorded. Results:  Median survival from disease onset was 842 days [interquartile range (IQR) 573–1263]. Median time from disease onset to feeding tube was PEG 521 days (IQR 443–1032), RIG 633 days (IQR 496–1039) and NGT 427 days (IQR 77–781) (P = 0.28). Median survival from tube placement was PEG 200 (IQR 106–546) days, RIG 216 (IQR 83–383) days and NGT 28 (IQR 14–107) days. Survival between gastrostomy and NGT treated patients was significant (P ≤ 0.001). Analysis of serious complications by nutritional status was BMI (P = 0.347) and % WL (P = 0.489). Conclusions:  Nutritional factors associated with reduced survival were weight loss, malnutrition and severe dysphagia. Serious complications were not related to nutritional status but to method of tube insertion. There was no difference in survival between PEG and RIG treated patients.     

Comparative Analysis of the Efficacy and Complications of Nasojejunal and Jejunostomy on Patients Undergoing Pancreaticoduodenectomy

Background: The efficacy and feeding‐related complications of a nasojejunal feeding tube and jejunostomy after pancreaticoduodenectomy (PD) was investigated with a randomized, controlled clinical trial at the Affiliated Drum Tower Hospital. Methods: Sixty‐eight patients who underwent PD in the Department of Hepatobiliary Surgery were randomly divided into 2 groups: 34 patients received enteral feeding via a nasojejunal tube (NJT group) and 34 patients received enteral feeding via a jejunostomy tube (JT group). The assessment of clinical outcome was based on postoperative investigation of complications. The second part of the assessment included tube related complications and an index on catheter efficiency. Results: There were 15 cases with infectious complications in the JT group and 13 cases in the NJT group, and there was no significant difference in the rate of infectious complications between the 2 groups. The rate of intestinal obstruction and delayed gastric emptying was significantly decreased in the NJT group (P < .05). Catheter‐related complications were more common in the JT group as compared with the NJT group (35.3% vs 20.6%, P < .05). The time for removal of the feeding tube and nasogastric tube was significantly decreased in the NJT group. The postoperative hospital stay in the NJT group was significantly decreased (P < .05), and there was no hospital mortality in this study. Conclusion: Nasojejunal feeding is safer than jejunostomy, and it is associated with only minor complications. Nasojejunal feeding can significantly decrease the incidence of delayed gastric emptying and shorten the postoperative hospital stay.     

Self‐Insertion of a Nasogastric Tube for Home Enteral Nutrition

Background: Enteral tube feeding can be a source of discomfort and reluctance from patients. We evaluated for the first time the tolerability of self‐insertion of a nasogastric (NG) tube for home enteral nutrition (EN). Materials and Methods: All patients requiring enteral tube feeding for chronic diseases were enrolled in a therapeutic patient education (TPE) program at Nancy University Hospital. Results: In our department, between November 2008 and August 2012, 66 patients received EN with an NG tube. Twenty‐nine of 66 had self‐insertion of the NG tube (median age, 44 years), 17 had an anatomical contraindication, and 20 were excluded because of cognitive disability or language barrier or refusal. Twenty‐eight of 29 patients completed the TPE program. One patient died of pancreatic cancer in palliative care during the study. Median follow‐up was 20 months (interquartile range [IQR], 4–31). Median gain weight was 3.1 kg (IQR, 1.8–6.0) (P = .0002). Median duration of self‐insertion of the NG tube was 3 months (IQR, 2–5), and it was well tolerated by all 29 patients. Two patients described minor adverse events: abdominal pain and nausea for 1 patient and epistaxis leading to temporary discontinuation of EN for another patient. A group of 10 consecutive patients previously had a long‐term NG tube for EN. If they had the choice between a self‐inserted NG tube and a long‐term NG tube, all 10 patients reported they would prefer to start again with the self‐inserted NG tube. Conclusion: This pilot study suggests that self‐insertion of an NG tube may be efficacious and well tolerated in patients receiving EN for chronic conditions.     

Impact of Process Optimization and Quality Improvement Measures on Neonatal Feeding Outcomes at an All‐Referral Neonatal Intensive Care Unit

Aim: We hypothesized that the implementation of a feeding quality improvement (QI) program among premature neonates accelerates feeding milestones, safely lowering hospital length of stay (LOS) compared with the baseline period. Methods: Baseline data were collected for 15 months (N = 92) prior to initiating the program, which involved development and implementation of a standardized feeding strategy in eligible premature neonates. Process optimization, implementation of feeding strategy, monitoring compliance, multidisciplinary feeding rounds, and continuous education strategies were employed. The main outcomes included the ability and duration to reach enteral feeds–120 (mL/kg/d), oral feeds–120 (mL/kg/d), and ad lib oral feeding. Balancing measures included growth velocities, comorbidities, and LOS. Results: Comparing baseline versus feeding program (N = 92) groups, respectively, the feeding program improved the number of infants receiving trophic feeds (34% vs 80%, P < .002), trophic feeding duration (14.8 ± 10.3 days vs 7.6 ± 8.1 days, P < .0001), time to enteral feeds–120 (16.3 ± 15.4 days vs 11.4 ± 10.4 days, P < .04), time from oral feeding onset to oral feeds–120 (13.2 ± 16.7 days vs 19.5 ± 15.3 days, P < .0001), time from oral feeds–120 to ad lib feeds at discharge (22.4 ± 27.2 days vs 18.6 ± 21.3 days, P < .01), weight velocity (24 ± 6 g/d vs 27 ± 11 g/d, P < .03), and LOS (104.2 ± 51.8 vs 89.3 ± 46.0, P = .02). Mortality, readmissions within 30 days, and comorbidities were similar. Conclusions: Process optimization and the implementation of a standardized feeding strategy minimize practice variability, accelerating the attainment of enteral and oral feeding milestones and decreasing LOS without increasing adverse morbidities.     

Placement of a Magnetic Small Bowel Feeding Tube at the Bedside

Background: Current methods of achieving postpyloric enteral access for feeding are fraught with difficulties, which can markedly delay enteral feeding and cause complications. Bedside tube placement has a low success rate, often requires several radiographs to confirm position, and delays feeding by many hours. Although postpyloric enteral tubes can reliably be placed in interventional radiology (IR), this involves greater resource utilization, delays, cost, and inconvenience. We assessed the utility of bedside enteral tube placement using a magnetic feeding tube (Syncro‐BlueTube; Syncro Medical Innovations, Macon, GA, USA) as a means to facilitate initial tube placement. Methods: We recorded the time to insertion, location of tube, success rate, and need for radiographs in a series of patients given magnetic feeding tubes (n = 46) inserted by our hospitalist service over an 8‐month interval. Results: Of the 46 attempted magnetic tube placements, 76% were successfully placed in the postpyloric position, 13% were in the stomach, and 11% could not be placed. In 83% of the magnetic tubes, only 1 radiograph was needed for confirmation. The median time to placement was 12 minutes (range, 4–120 minutes). Conclusion: The use of a magnetic feeding tube can increase the success rate of bedside postpyloric placement, decrease the time to successful placement, and decrease the need for supplemental radiographs and IR.

目的:观察胰十二指肠切除术中经胃造口管放置空肠营养管的临床疗效和病人的生存质量。方法:将25例胰十二指肠切除术病人随机分为术中经胃造口管放置空肠营养管(观察组)和传统放置胃管EN治疗(对照组),对比两组病人的手术操作时间、术后并发症、住院费用、住院时间,术后第7和第14天抑郁自评量表和焦虑自评量表评分、免疫和营养状况等指标的差异和生活质量评分(QLQ-C30)的差异。结果:观察组病人均在术中成功经胃造口管放置空肠营养管,无发生导管相关并发症,未增加手术时间、住院费用和住院时间。两组病人抑郁与焦虑评分均有显著性差异(P<0.05),术后QLQ-C30评分差异亦有显著性意义。两组病人营养状况和免疫功能指标无显著性差异。结论:胰十二指肠切除病人术中经胃造口管放置空肠营养管是安全有效的肠内营养途径,有助于提高病人的生活质量。     

Multitargeted Feeding Strategies Improve Nutrition Outcome and Are Associated With Reduced Pneumonia in a Level 1 Trauma Intensive Care Unit

Background: Factors impeding delivery of adequate enteral nutrition (EN) to trauma patients include delayed EN initiation, frequent surgeries and procedures, and postoperative ileus. We employed 3 feeding strategies to optimize EN delivery: (1) early EN initiation, (2) preoperative no nil per os feeding protocol, and (3) a catch‐up feeding protocol. This study compared nutrition adequacy and clinical outcomes before and after implementation of these feeding strategies. Methods: All trauma patients aged ≥18 years requiring mechanical ventilation for ≥7 days and receiving EN were included. Patients who sustained nonsurvivable injuries, received parenteral nutrition, or were readmitted to the intensive care unit (ICU) were excluded. EN data were collected until patients received an oral diet or were discharged from the ICU. The improvement was quantified by comparing nutrition adequacy and outcomes between April 2014–May 2015 (intervention) and May 2012–June 2013 (baseline). Results: The intervention group (n = 118) received significantly more calories (94% vs 75%, P < .001) and protein (104% vs 74%, P < .001) than the baseline group (n = 121). The percentage of patients receiving EN within 24 and 48 hours of ICU admission increased from 41% to 70% and from 79% to 96% respectively after intervention (P < .001). Although there were fewer 28‐ay ventilator‐free days in the intervention group than in the baseline group (12 vs 16 days, P = .03), receipt of the intervention was associated with a significant reduction in pneumonia (odds ratio, 0.53; 95% confidence interval, 0.31–0.89; P = .017) after adjusting sex and Injury Severity Score. Conclusions: Implementation of multitargeted feeding strategies resulted in a significant increase in nutrition adequacy and a significant reduction in pneumonia.     

Fat‐Modified Enteral Formula Improves Feeding Tolerance in Critically Ill Patients: A Multicenter,Single‐Blind,Randomized Controlled Trial

Background: Improvement of fat digestion and absorption was supposed to relieve feeding intolerance. This trial aimed to evaluate the effect of a fat‐modified enteral formula on feeding tolerance in critically ill patients. Materials and Methods: This trial was conducted in 7 hospitals in China. In total, 144 intensive care unit (ICU) patients with estimated need of enteral nutrition (EN) for at least 5 days were randomly given fat‐modified enteral formula containing medium‐chain triglycerides (MCT), carnitine, and taurine (interventional feed group, n = 71) or standard enteral formula (control feed group, n = 73). EN intake, feeding intolerance (diarrhea, vomiting, gastric retention, and abdominal distension) and outcomes (mechanical ventilator‐free days of 28 days, length of ICU stay, length of hospital stay, and in‐hospital mortality) were collected. Results: Daily calories and protein intake were increased in the interventional feed group compared with the control feed group (P < .01). Total incidence of feeding intolerance was 42.3% in the interventional feed group and 65.7% in the control feed group (P < .001). Daily incidence of feeding intolerance was 11.3%, 18.3%, 14.1%, 25.4%, and 26.1% in the interventional feed group and 31.5%, 32.9%, 34.2%, 34.2%, and 30.4% in the control feed group from study days 1–5 (P = .0083). Incidence of feeding intolerance without abdominal distention was 32.9% in the interventional feed group and 49.3% in the control feed group (P = .047), while the incidence of abdominal distension was 26.8% in the interventional feed group and 43.8% in the control feed group (P = .03). No significant differences existed in outcomes between the 2 groups. Conclusions: The fat‐modified enteral formula containing MCT, carnitine, and taurine may improve feeding tolerance in critically ill patients.     

Enteral feeding induces early intestinal adaptation in a parenterally fed neonatal piglet model of short bowel syndrome

Background: Successful small intestinal (SI) adaptation following surgical resection is essential for optimizing newborn growth and development, but the potential for adaptation is unknown. The authors developed an SI resection model in neonatal piglets supported by intravenous and enteral nutrition. Methods: Piglets (n = 33, 12–13 days old) were randomized to 80% SI resection with parenteral nutrition feeding (R‐PN), 80% SI resection with PN + enteral feeding (R‐EN), or sham SI transection with PN + enteral feeding (sham‐EN). In resected pigs, the distal 100 cm of ileum (residual SI) and 30 cm of proximal SI were left intact. All pigs received parenteral nutrition postsurgery. Enteral nutrition piglets received continuous gastric infusion of elemental diet from day 3 (40:60 parenteral nutrition:enteral nutrition). Piglets were killed 4, 6, or 10 days postsurgery. Results: By 10 days, R‐EN piglets had longer residual SI than R‐PN and sham‐EN pigs (P < .05). At days 6 and 10, R‐EN piglets had greater weight per length of intact SI (P < .05) and isolated mucosa (P < .05) compared to other groups. Greater gut weight in R‐EN piglets was facilitated by a greater cellular proliferation index (P < .01) by 4 days compared to other groups and greater overall ornithine decarboxylase activity vs R‐PN piglets (P < .05). Conclusions: This new model demonstrated profound SI adaptation, initiated early postsurgery by polyamine synthesis and crypt cell proliferation and only in response to enteral feeding. These changes translated to greater gut mass and length within days, likely improving functional capacity long term.     

Home Nasogastric Feeds

Background: Home enteral nutrition (HEN) is a safe method for providing nutrition to children with chronic diseases. Advantages of HEN include shorter hospitalizations, lower cost, and decreased risk of malnutrition‐associated complications. Follow‐up after hospital discharge on HEN is limited. The purpose of this study was to look at children discharged on nasogastric (NG) feeds to assess follow‐up feeding status and impact on growth. Methods: A retrospective chart review was conducted of pediatric patients discharged from Mount Sinai Medical Center on NG feeds between January 2010 and March 2013. Results: A total of 87 patients were included. Average age was 1.2 years. The most common diagnoses were congenital heart disease (47%), metabolic disease (17%), neurologic impairment (10%), liver disease (9%), prematurity (8%), and inflammatory bowel disease (6%). At most recent follow‐up, 44 (50.6%) were on full oral feeds, 8 (9.2%) were still on NG feeds, 9 (10.3%) had a gastrostomy tube placed, 9 (10.3%) were deceased, and 17 (19.5%) had transferred care or were lost to follow‐up. Average time to discontinuation of NG feeds was 4.8 months. Change in body mass index from hospital discharge to follow‐up visit 6 to 12 weeks after discharge was statistically significant, from a mean (SD) of 13.78 (2.82) to 14.58 (2.1) (P = .02). Change in weight z score was significant for neurologic impairment (?1.35 to ?0.04; P = .03). Height z score change was significant for prematurity (?3.84 to ?3.34; P = .02). There was no significant change in height or weight z scores for the other diagnoses. Conclusions: NG feeds can help to improve short‐term growth after hospital discharge in children with chronic illnesses.     

Glycemic Control in Patients With Type 2 Diabetes Mellitus With a Disease‐Specific Enteral Formula: Stage II of a Randomized,Controlled Multicenter Trial

Background: Stage I of a preplanned 2‐stage study has provided good evidence for improved glycemic control with a disease‐specific enteral formula low in carbohydrates and high in monounsaturated fatty acids (MUFAs), fish oil, chromium, and antioxidants in insulin‐treated type 2 diabetes. The study was continued with stage II to give confirmatory proof of these beneficial effects. Methods: 105 patients with HbA_1C ≥ 7.0% and/or fasting blood glucose (FG) > 6.7 mmol/L (>120 mg/dL) requiring enteral tube feeding due to neurological dysphagia received 113 kJ (27 kcal)/kg body weight of either test formula (Diben) or an isoenergetic, isonitrogenous standard formula (control) for up to 84 days. Total insulin (TI) requirements, FG, and afternoon blood glucose (AG) were assessed daily. HbA_1C and safety criteria were evaluated on days 1, 28, 56, and 84. Results: 55 patients completed the study; on day 84, median changes from baseline (data as available, test vs control) were the following: TI,– 8.0 vs +2.0 IU; FG, –2.17 vs –0.67 mmol/L (–39.0 vs– 12.1 mg/dL); HbA_1C, –1.30% vs –1.20%; AG,– 2.36 vs –0.49 mmol/L (–42.5 vs –8.9 mg/dL). The number of relevant hypoglycemic episodes (FG < 3.33 mmol/L < 60 mg/dL) was 1 vs 5. Feeding tolerance was comparable in both groups. Conclusions: Long‐term tube feeding with a disease‐specific enteral formula was safe and well tolerated in type 2 diabetic patients with neurological disorders. When compared with a standard diet, TI requirement decreased significantly with less hypoglycemia whereas FG and AG were significantly lowered, resulting in improved glycemic control.     

Bedside placement of small bowel feeding tubes in hospitalized patients: a new role for the dietitian

OBJECTIVE: The benefits of enteral nutrition when compared with parenteral nutrition are well established. However, provision of enteral nutrition may not occur for several reasons, including lack of optimal feeding access. Gastric feeding is easier to initiate, but many hospitalized patients are intolerant to gastric feeding, although they can tolerate small bowel feeding. Many institutions rely on costly methods for placing small bowel feeding tubes. Our goal was to evaluate the effectiveness of a hospital-developed protocol for bedside-blind placement of postpyloric feeding tubes. METHODS: The Surgical Nutrition Service established a protocol for bedside placement of small bowel feeding tubes. The protocol uses a 10- or 12-French, 110-cm stylet containing the feeding tube; 10 mg of intravenous metoclopramide; gradual tube advancement followed by air injection and auscultation; and an abdominal radiograph for tube position confirmation. In a prospective manner, consults received by the surgical nutrition dietitian for feeding tube placements were followed consecutively for a 10-mo period. The registered dietitian recorded the number of radiograph examinations, the final tube position, and the time it took to achieve tube placement. RESULTS: Because all consults were included, feeding tube placements occurred in surgical and medical patients in the intensive care unit and on the ward. Of the 135 tube placements performed, 129 (95%) were successfully placed postpylorically, with 84% (114 of 135) placed at or beyond D3. Average time for tube placement was 28 min (10 to 90 min). One radiograph was required for 92% of the placements; eight of 135 (6%) required two radiographs. No acute complications were associated with the tube placements. CONCLUSIONS: Hospitalized patients can receive timely enteral feeding with a cost-effective feeding tube placement protocol. The protocol is easy to implement and can be taught to appropriate medical team members through proper training and certification.     

Prolonged Versus Short-Duration Use of Nasogastric Tubes in Patients with Head and Neck Cancer During Radiotherapy Alone or Combined Chemoradiotherapy

To compare safety and effectiveness of prolonged (>28 days) versus short duration (≤28 days) use of nasogastric tube for enteral nutrition and weight loss prevention during curative radiotherapy with or without concurrent chemotherapy or cetuximab for head and neck cancer patients. We performed a retrospective study and database review of all patients at our center, treated with radiotherapy for head and neck cancer receiving enteral nutrition by nasogastric tube. Type of treatment, weight and body mass index changes, and related complications (gastroesophageal reflux, pneumonia, ulcer, feeding tube obstruction, or dislocation) were documented. Comparison between patients with prolonged (>28 days, group A) and short duration (≤28 days, group B) of EN through nasogastric tube was performed. Data expressed as mean?±?SD or median (min; max) values as appropriate, and analyzed by ANOVA repeated measures and Kaplan-Meier estimates. We identified 114 patients who fulfilled the inclusion criteria. Among them, 10% were treated with radiotherapy alone, while 90% received concurrent chemotherapy or cetuximab. Ninety-four patients (82%, group A) had a nasogastric tube in place for a period >28 days and 20 (18%, group B) for ≤28 days during treatment. Patients were mainly men (86 patients, 75%), with a median age of 61 years (range 49–73) and advanced stage IV disease in most cases (87 patients, 76%) without differences between both groups (p = 0.53, 0.47, and 0.30, respectively). Treatment discontinuation did not occur within both groups. Fifty-six patients (49%) developed complications, without a significant difference between both groups (P = 0.23). Body weight and BMI changes did not differ during EN (–0.8?±?4.5 and –0.3?±?1.6), the oncological treatment (–5.3?±?4.0 and –1.8?±?1.4), or 6 months after the end of treatment (–0.6?±?4.4 and –0.2?±?1.5). Our findings suggest that prolonged enteral nutrition by nasogastric tube is safe and effective in preventing weight loss during curative radiotherapy or radio-chemotherapy for head and neck cancer.     

Nasointestinal intubation with tiger tubes: a case series indicates risk of mucosal damage

Abstract In five intubations using the tiger tube (Cook) two were successfully placed into the small intestine. Two of the three intubation failures were due to early death due to the underlying condition. Nasointestinal placement permitted successful enteral feeding. Unfortunately, both nasointestinal placements were associated with mucosal damage that appears to be related to the tube "flaps". The tiger tube facilitates nasointestinal tube placement but until concerns regarding safety are addressed its clinical use cannot be recommended.     

Magnetic Resonance–Guided Nasogastric Feeding Tube Placement for Neonates: A Preclinical Study

Background: Establishing postnatal nutrition delivery is challenging in neonates with immature sucking and swallowing ability. Enteral feeding is the gold standard for such patients, but their small size and fragility present challenges in nasogastric (NG) feeding tube placement. Feeding tubes are typically placed with x‐ray guidance, which provides minimal soft tissue contrast and exposes the baby to ionizing radiation. This research investigates magnetic resonance (MR) guidance of NG feeding tube placement in neonates to provide improved soft tissue visualization without ionizing radiation. Materials and Methods: A novel feeding tube incorporating 3 solenoid coils for real‐time tracking and guidance in the MR environment was developed. The feeding tube was placed 5 times in a rabbit with conventional x‐ray guidance to assess mechanical stability and function. After x‐ray procedures, the rabbit was transferred to a neonatal MR system, and the tube was placed 5 more times. Results: In procedures guided by x‐ray and MR, the feeding tube provided sufficient mechanical strength and functionality to access the esophagus and stomach of the rabbit. MR imaging provided significantly improved soft tissue contrast versus x‐ray, which aided in proper tube guidance. Moreover, MR guidance allowed for real‐time placement of the tube without the use of ionizing radiation. Conclusions: The feasibility and benefits offered by an MR‐guided approach to NG feeding tube placement were demonstrated. The ability to acquire high‐quality MR images of soft tissue without ionizing radiation and a contrast agent, coupled with accurate 3‐dimensional device tracking, promises to have a powerful impact on future neonatal feeding tube placements.
