Jejunal feeding tubes can be efficiently and independently placed by intensive care unit teams

Nutritional Management of Patients with Head and Neck Cancer-A Comprehensive Review

While surgical therapy for head and neck cancer (HNC) is showing improvement with the advancement of reconstruction techniques, the focus in these patients should also be shifting to supportive pre and aftercare. Due to the highly sensitive and anatomically complex region, these patients tend to exhibit malnutrition, which has a substantial impact on their recovery and quality of life. The complications and symptoms of both the disease and the therapy usually make these patients unable to orally intake food, hence, a strategy should be prepared for their nutritional management. Even though there are several possible nutritional modalities that can be administrated, these patients commonly have a functional gastrointestinal tract, and enteral nutrition is indicated over the parenteral option. However, after extensive research of the available literature, it seems that there is a limited number of studies that focus on this important issue. Furthermore, there are no recommendations or guidelines regarding the nutritional management of HNC patients, pre- or post-operatively. Henceforth, this narrative review summarizes the nutritional challenges and management modalities in this particular group of patients. Nonetheless, this issue should be addressed in future studies and an algorithm should be established for better nutritional care of these patients.

Postpyloric feeding tube placement at the bedside: Complication rate and impact on length of stay

BACKGROUND

Postpyloric feeding tube (PPFT) placement is essential for the ongoing nutrition care of critically ill children requiring noninvasive and invasive ventilation. PPFTs are placed by a variety of providers, including advanced practice nurses (APNs), surgeons, gastroenterologists, and radiologists. Complication rates, time to enteral nutrition (EN) following placement, and association with length of stay (LOS) have not been well documented.

METHODS

A query of the electronic medical record identified patients in the pediatric intensive care unit (PICU) in whom PPFTs were placed. A retrospective chart review was performed to identify patient demographics; PPFT placement provider, indication, and duration; PICU LOS; hospital LOS; and patient pediatric risk of mortality (PRISM) scores.

RESULTS

A total of 452 PPFTs were placed in 346 patients , with 318 placed by APNs. There was only one complication in 452 placed PPFTs. PRISM scores between patient groups for APN-placed PPFTs and non-APN-placed PPFTs were not significantly different. Mean time from hospital admission to PPFT placement was 1.5 days (APN) to 2.0 days (non-APN) (P < .02). Spearman correlation coefficients demonstrated shorter hospital and PICU LOS were associated with shorter duration to insertion.

CONCLUSION

Overall complication rates of PPFT insertion is very low and do not significantly differ between provider type , even in patients with higher PRISM scores. Additionally, early time to insertion of PPFT is associated with decreased hospital and PICU LOS. Further research is needed to determine if the earlier time to insertion of PPFTs is associated with the achievement of goal feeds.

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.

Development of a Competency Model for Placement and Verification of Nasogastric and Nasoenteric Feeding Tubes for Adult Hospitalized Patients

Nasogastric/nasoenteric (NG/NE) feeding tube placements are associated with adverse events and, without proper training, can lead to devastating and significant patient harm related to misplacement. Safe feeding tube placement practices and verification are critical. There are many procedures and techniques for placement and verification; this paper provides an overview and update of techniques to guide practitioners in making clinical decisions. Regardless of placement technique and verification practices employed, it is essential that training and competency are maintained and documented for all clinicians placing NG/NE feeding tubes. This paper has been approved by the American Society for Parenteral and Enteral Nutrition (ASPEN) Board of Directors.

Electromagnetically guided bedside placement of post-pyloric feeding tubes in critical care

Post-pyloric feeding is recommended in critically ill patients with gastro-intestinal intolerance. However, traditional placement methods are logistically difficult and carry potential risks. The authors retrospectively compared the position of post-pyloric feeding tubes (PPFTs) using an electromagnetic device that demonstrated by X-ray and analysed the complication rates, proportion of lung placements avoided and the time taken to establish enteral feeding. Forty placements in 37 mechanically ventilated patients were analysed; there was a success rate of 87.5%. Sensitivity and specificity were 77% (95% CI 59.9-89.6%) and 100% (95% CI 48.0-100%). Five lung placements were identified in real time and therefore avoided. The mean (SD) time from PPFT placement to X-ray was 134 minutes (± 139 minutes) and, to feeding, 276 minutes (± 213 minutes). In conclusion, placement of PPFT using an electromagnetic device carries a high success rate, is safe and feasible to undertake at the bedside in mechanically ventilated patients.

A novel quick transendoscopic enteral tubing in mid-gut: technique and training with video

Background

This study aimed to evaluate the feasibility, safety, and value of a quick technique for transendoscopic enteral tubing (TET) through mid-gut.

Methods

A prospective interventional study was performed in a single center. A TET tube was inserted into mid-gut through the nasal orifice and fixed on the pylorus wall by one tiny titanium endoscopic clip under anesthesia. The feasibility, safety, success rate, and satisfaction with TET placement were evaluated for enteral nutrition or fecal microbiota transplantation.

Results

A total of 86 patients underwent mid-gut TET. The success rate of the TET procedure was 98.8% (85/86). Mean tubing time of the TET procedure was 4.2 ± 1.9 min. 10 cases of procedure was enough for training of general endoscopist to shorten the procedure time (7.0 min vs 4.0 min, p < 0.05). 97.7% (84/86) of patients were satisfied with the TET placement. Procedure-related and tube-related adverse events were observed in 8.1% (7/86) and 7.0% (6/86) of patients respectively. There were no moderate to severe adverse events during tube extubation.

Conclusions

TET through mid-gut is a novel, convenient, reliable and safe procedure for mid-gut administration with a high degree of patient satisfaction.

Enteral Nutrition: Options for Short-Term Access

The preferred method of nutrition support in the presence of a functional gastrointestinal tract is enteral nutrition (EN). Many factors contribute to the selection process for the type of enteral access device to be used. Short-term enteral access tubes are placed into the nares or, sometimes, orally, usually at bedside. The short-term access provides a means to meet patient nutrient needs and can provide a chance to assess tolerance of the tube feedings if more permanent long-term placement is determined to be required. Access for nutrition support does not come without a risk; it can be challenging, requiring an individualized approach for each patient. The selection type and access location can greatly impact the success of EN. The most advantageous tube choice must be determined carefully, taking into account the multiple considerations reviewed in this paper.

Endoscopy versus fluoroscopy for the placement of postpyloric nasoenteric tubes in critically ill patients: A meta-analysis of randomized controlled trials

INTRODUCTION

Early postpyloric nasoenteric nutrition is considered an accepted method of nutritional support in critically ill patients. Both endoscopy and fluoroscopy placement of postpyloric nasoenteric tubes (PNTs) have the highest percentages of placement success rate. We aimed to evaluate the differences in efficacy and safety between endoscopy and fluoroscopy methods for the placement of PNTs in critically ill patients.

METHOD

We searched MEDLINE, Embase, and electronic databases of Cochrane Central Register of Controlled Trials. We included randomized controlled trials comparing endoscopy and fluoroscopy placement of PNTs in critically ill patients. Two reviewers assessed the quality of each study and collected data independently. We performed the meta-analysis with Cochrane Collaboration RevMan 5.3.

RESULTS

Three randomized controlled trials involving 243 patients were included. There were no significant differences in the placement success rate (RR, 0.99; 95% CI, 0.93, 1.06; z = 0.20, P = .84,) or procedure time (standardized mean difference, -0.08; 95% CI, -6.93, 6.77; z = 0.02, P = .98) between the 2 groups. No severe complications (digestive tract hemorrhage, perforation, respiratory problems, hemodynamic instability, or death) were noted in the three studies. There was a slight difference in the incidence of minor complications (RR, 8.12; 95% CI, 1.07, 61.53; z = 2.03, P = .04) between the 2 groups.

CONCLUSIONS

Endoscopy and fluoroscopy placement of PNTs can be accurately and safely performed in critically ill patients. Endoscopy may be at least equally as safe as fluoroscopy for the placement of PNTs.

Clinical management of post-pyloric enteral feeding in children

Post-pyloric feeding (PF) allows the administration of enteral nutrition beyond the pylorus, either into the duodenum or, ideally, into the jejunum. The main indications of PF are: upper gastrointestinal tract obstructions, pancreatic rest (e.g., acute pancreatitis), gastric dysmotility (e.g., critically ill patients and chronic intestinal pseudo-obstruction) or severe gastroesophageal reflux with risk of aspiration (e.g., neurological disability). Physiological and clinical evidence derives from adults, but can also be pertinent to children. This review will discuss the practical management and potential clinical applications of PF in pediatric patients. Some key studies pertaining to the physiological changes during PF will also be considered because they support the strategy of PF management.

Systematic review on bedside electromagnetic-guided, endoscopic, and fluoroscopic placement of nasoenteral feeding tubes

BACKGROUND

Nasoenteral tube feeding is frequently required in hospitalized patients to either prevent or treat malnutrition, but data on the optimal strategy of tube placement are lacking.

OBJECTIVE

To compare the efficacy and safety of bedside electromagnetic (EM)-guided, endoscopic, and fluoroscopic placement of nasoenteral feeding tubes in adults.

DESIGN

Systematic review of the literature.

PATIENTS

Adult hospitalized patients requiring nasoenteral feeding.

INTERVENTIONS

EM-guided, endoscopic, and/or fluoroscopic nasoenteral feeding tube placement.

MAIN OUTCOME MEASUREMENTS

Success rate of tube placement and procedure- or tube-related adverse events.

RESULTS

Of 354 screened articles, 28 studies were included. Data on 4056 patients undergoing EM-guided (n = 2921), endoscopic (n = 730), and/or fluoroscopic (n = 405) nasoenteral feeding tube placement were extracted. Tube placement was successful in 3202 of 3789 (85%) EM-guided procedures compared with 706 of 793 (89%) endoscopic and 413 of 446 (93%) fluoroscopic procedures. Reinsertion rates were similar for EM-guidance (270 of 1279 [21%] patients) and endoscopy (64 of 394 [16%] patients) or fluoroscopy (10 of 38 [26%] patients). The mean (standard deviation) procedure time was shortest with EM-guided placement (13.4 [12.9] minutes), followed by endoscopy and fluoroscopy (14.9 [8.7] and 16.2 [23.6] minutes, respectively). Procedure-related adverse events were infrequent (0.4%, 4%, and 3%, respectively) and included mainly epistaxis. The tube-related adverse event rate was lowest in the EM-guided group (36 of 242 [15%] patients), followed by fluoroscopy (40 of 191 [21%] patients) and endoscopy (115 of 384 [30%] patients) and included mainly dislodgment and blockage of the tube.

LIMITATIONS

Heterogeneity and limited methodological quality of the included studies.

CONCLUSION

Bedside EM-guided placement of nasoenteral feeding tubes appears to be as safe and effective as fluoroscopic or endoscopic placement. EM-guided tube placement by nurses may be preferred over more costly procedures performed by endoscopists or radiologists, but randomized studies are lacking.

Dual-Purpose Gastric Decompression and Enteral Feeding Tubes Rationale and Design of Novel Nasogastric and Nasogastrojejunal Tubes

BACKGROUND

The importance of early postoperative nutrition in surgical patients and early institution of enteral nutrition in intensive care unit (ICU) patients have recently been highlighted. Unfortunately, institution of enteral feeding in both groups of patients often has to be postponed due to delayed gastric emptying and the need for gastric decompression. The design of current polyvinylchloride (PVC) gastric decompression tubes (Salem Sump [Covidien, Mansfield, MA] in the United States; Ryles [Penine Health Care Ltd, Derby, UK] in the United Kingdom and Europe) make them unsuitable for their subsequent use as either nasogastric enteral feeding tubes or for continued gastric decompression during postpyloric enteral feeding. To overcome these problems, we have designed a range of polyurethane (PU) dual-purpose gastric decompression and enteral feeding tubes that include 2 nasogastric tubes (double lumen to replace Salem Sump; single lumen to replace Ryles). Two novel multilumen nasogastrojejunal tubes (triple lumen for the United States; double lumen for the United Kingdom and Europe) complete the range. By using PU, a given internal diameter (ID) and flow area can be incorporated into a lower outside diameter (OD) compared with that achieved with PVC. The ID and lumen and flow area of an 18Fr (OD 6.7 mm) PVC Salem Sump can be incorporated into a 14Fr (OD 4.7 mm) PU tube. The design of aspiration/infusion ports of current PVC and PU tubes invites occlusion by gastrointestinal mucosa and clogging by mucus and enteral feed. To overcome this, we have designed long, single, widened, smooth, and curved edge ports with no "dead space" to trap mucus or curdled diet. Involving up to 214° of the circumference, these ports have up to 11 times the flow areas of the aspiration ports of current PVC tubes.

CONCLUSION

The proposed designs will lead to the development of dual-purpose nasogastric and nasojejunal tubes that will significantly improve the clinical and nutrition care of postoperative and ICU patients.

Perioperative nutrition: what is the current landscape?

Poor nutrition status has long been linked to increases in postoperative complications and adverse outcomes for the patient undergoing elective surgery. While optimal planning for nutrition therapy should be comprehensive spanning throughout the perioperative period, recent advances have focused on the concept of "prehabilitation" to best prepare the patient prior to the insult of surgery. Adding immune/metabolic modulating formulas the week of surgery with carbohydrate drinks to optimize glycogen deposition immediately prior to surgery, enhances patient recovery and return to baseline function. Such nutrition strategies should now be combined with a host of other practices (such as smoking cessation, weight loss, glucose control, and specialized exercise program) as part of a structured protocol to maximize patients' chances for a full and rapid recovery from their elective surgical procedure.

Are prospective cohort studies an appropriate tool to answer clinical nutrition questions?

PURPOSE OF REVIEW

Randomized controlled trials can be difficult to conduct in critically ill patients and may not always be the most appropriate type of study. Cohort studies can provide valuable information in large complete populations of patients without strict exclusion criteria and without the need for informed consent, thus potentially being more representative of and applicable to daily practice.

RECENT FINDINGS

Recent cohort studies have evaluated the various aspects of the epidemiology and practice of nutrition in critically ill patients, including the proportions of patients receiving different types of nutritional support, the potential benefits of supplementary parenteral nutrition, the importance of meeting nutrition targets especially for protein, and the beneficial effects of feeding protocols on outcomes.

SUMMARY

Results from some of these cohort studies have provided an indication of how nutrition guidelines have been applied in clinical practice and which areas need to be improved. Others have generated hypotheses that will be (or are already being) tested in randomized studies.

Evaluation of a new method for placing nasojejunal feeding tubes

AIM: To compare fluoroscopic, endoscopic and guide wire assistance with ultraslim gastroscopy for placement of nasojejunal feeding tubes.

METHODS: The information regarding nasojejunal tube placement procedures was retrieved using the gastrointestinal tract database at Tongji Hospital affiliated to Tongji Medical College. Records from 81 patients who underwent nasojejunal tubes placement by different techniques between 2004 and 2011 were reviewed for procedure success and tube-related outcomes.

RESULTS: Nasojejunal feeding tubes were successfully placed in 78 (96.3%) of 81 patients. The success rate by fluoroscopy was 92% (23 of 25), by endoscopic technique 96.3% (26 of 27), and by guide wire assistance (whether via transnasal or transoral insertion) 100% (23/23, 6/6). The average time for successful placement was 14.9 ± 2.9 min for fluoroscopic placement, 14.8 ± 4.9 min for endoscopic placement, 11.1 ± 2.2 min for guide wire assistance with transnasal gastroscopic placement, and 14.7 ± 1.2 min for transoral gastroscopic placement. Statistically, the duration for the third method was significantly different (P < 0.05) compared with the other three methods. Transnasal placement over a guidewire was significantly faster (P < 0.05) than any of the other approaches.

CONCLUSION: Guide wire assistance with transnasal insertion of nasojejunal feeding tubes represents a safe, quick and effective method for providing enteral nutrition.
