Experience in Bedside Placement, Clinical Validity, and Cost-Efficacy of a Self-Propelled Nasojejunal Feeding Tube

Comparison of the use of a spiral nasojejunal tube and transendoscopic enteral tubing in washed microbiota transplantation via the mid-gut route

Background

Methods for washed microbiota transplantation (WMT) through the mid-gut include transendoscopic enteral tubing (TET) and manual spiral nasojejunal tube (SNT) placement have not been studied.

Methods

This prospective interventional study was performed at a single centre. Patients were divided into the SNT and mid-gut TET groups based on their conditions and wishes. In the SNT group, an SNT was passively inserted into the stomach, and abdominal X-rays were taken within 24 h to confirm tube placement in the small intestine. In the mid-gut TET group, mid-gut TET was placed in the small intestine for gastroscopy. Data on the clinical efficacy of WMT, intubation time, cost, overall comfort score, adverse reactions, etc., were collected from the two groups.

Results

Sixty-three patients were included in the study (SNT group (n = 40) and mid-gut TET group (n = 23)). The clinical efficacy of WMT in the SNT and mid-gut TET groups was 90 % and 95.7 %, respectively (P = 0.644). Compared with the mid-gut TET group, the SNT group showed a shorter operation time (120 s vs. 258 s, P = 0.001) and a lower average cost (641.7 yuan vs. 1702.1 yuan, P = 0.001). There was no significant difference in the overall comfort score or the incidence of common discomfort symptoms between the two groups.

Conclusion

The different implantation methods have different advantages; compared with mid-gut TET placement, manual SNT placement provides some benefits.

Application of a downward tract adherence method in the manual bedside placement of post-pyloric tubes in the intensive care unit

BACKGROUND

At present, there are few studies on the technical requirements of manual bedside placement of post-pyloric tube in Intensive Care Unit patients.

OBJECTIVE

To investigate the application value of downward tract adherence method in the manual bedside placement of jejunal tubes.

METHODS

In the downward group, 160 patients underwent manual bedside placement of jejunal tubes by a downward tract adherence method. In the conventional group, 144 patients were treated with conventional gas injection during the placement. The success rate, average time, and adverse reactions of the placement in the two groups were investigated and compared.

RESULTS

The success rate of the placement in the downward group was significantly higher (95% vs. 75%, P< 0.001) and the average time for the successful placement was shortened (23 ± 5.91 min vs. 26 ± 5.49 min, P= 0.025) than that in the conventional group. No treatment-related adverse reactions occurred in either group, and there were also no significant differences in vital sign changes.

CONCLUSIONS

The use of the downward tract adherence method in the manual bedside placement of postpyloric tubes for the intensive care patients at the bedside has a higher success rate, effectivity and safety.

Choosing wisely: Enteral feeding tube selection, placement, and considerations before and beyond the procedure room

When an enteral feeding tube (EFT) is placed, it is not always known how long this nutrition support intervention will be needed. As a result, the type of device the patient originally has placed may not match the function it is required to serve or the lifestyle needs of the patient throughout their enteral nutrition journey. Medicare considers an EFT a prosthetic device, as it is replacing a permanently inoperable or nonfunctioning organ. If we think about an EFT the same way we think about a prosthetic limb, one that needs to be customized to meet all of the patient's functional and lifestyle needs, we can also begin to think beyond the procedure room and carefully consider a variety of factors that impact the patient at home receiving enteral nutrition. Proper fit, function, and style is essential in order for the patient to have a positive relationship with their EFT, contributing to their successful home enteral nutrition experience. Clinicians who care for these patients in any setting and in any capacity would benefit from enhancing their understanding of available EFT options, their design components, and available methods of placement. Many home care and outpatient clinicians adopt the role of patient advocate as it relates to a patient's enteral nutrition journey, and this expanded knowledge could be used to benefit the patient by improving their overall enteral nutrition experience and ultimately their relationship with their "prosthetic."

Nasointestinal tube placement: Techniques that increase success

Background

Delayed gastric emptying (DGE) is a major cause of undernutrition that can be overcome using nasointestinal (NI) feeding, but tube placement often fails. We analyse which techniques enable successful NI tube placement.

Methods

Efficacy of tube technique was determined at each of six anatomical points: Nose, nasopharynx-oesophagus, stomach-upper and -lower, duodenum part-1 and intestine.

Results

In 913 first NI tube placements, significant associations with tube advancement were found in the pharynx (head tilt, jaw thrust, laryngoscopy), stomach_upper (air insufflation, 10 cm or 20-30 cm flexible tube tip ± reverse Seldinger manoeuvre), stomach_lower (air insufflation, possibly flexible tip and wire stiffener) and duodenum part-1 and beyond part-2 (flexible tip and combinations of micro-advance, slack removal, wire stiffener or prokinetic drugs).

Conclusion

This is the first study to show what techniques are associated with tube advancement and the alimentary tract level they are specific to.

A Two-Stage Bedside Intubation Method to Improve Success Rate of Post-pyloric Placement of Spiral Nasoenteric Tubes in Critically Ill Patients: A Multi-Center, Prospective Study

Backgrounds

Prokinetic agents could improve the success rate of post-pyloric placement of self-propelled spiral nasoenteric tubes (NETs), and bedside blind technique might apply as a rescue therapy subsequent to spontaneous transpyloric migration failure. The objective of this study was to investigated the validity and safety of these two bedside intubation methods as a sequential procedure for post-pyloric placement of spiral NETs in critically ill patients.

Methods

The multicenter, prospective study was conducted in intensive care units of four tertiary hospitals (June 2020 to January 2021). Eligible patients received self-propelled spiral NET placements, promoted by prokinetic agents (Stage 1). An abdominal X-ray performed 24 h post-intubation confirmed the position of the tube tip. Patients with a failed transpyloric migration entered Stage 2, where beside blind intubation was conducted (reconfirmed by X-ray). The primary end point was the overall success rate of post-pyloric placement.

Results

The overall success rate of post-pyloric placement of the spiral NET was 91.1% (73.4% in the third portion of the duodenum [D3] or beyond). The total adverse event rate was 21.0%, without any serious adverse events. In Stage 1, 55.6% of participants achieved transpyloric migration, of these, 44.4% migrated to D3 or beyond. The median time from decision to intubate to the initiation of enteral nutrition (EN) was 25 h. In Stage 2, 83.0% of patients had successful post-pyloric intubation (67.9% in D3 or beyond). The median time from decision to EN initiation after the two-stage process was 36 h.

Conclusions

Prokinetic agents-assisted self-propelled intubation and remedial bedside blind technique as a sequential procedure for post-pyloric placement of spiral NETs were effective and safe, and this two-stage process did not affect the implementation of early EN in critically ill patients.

Nursing effect of Nasoscopically assisted nasogastri tube and nasojejunal tube placement

OBJECTIVE

To investigate the nursing effect of nasoscopically assisted nasogastri tube and nasojejunal tube placement.

METHODS

94 patients who need to place nasogastric tube and nasojejunal tube to establish enteral nutrition were randomly divided into two groups: the observation group (n=49) and control group (n=45). The patients in the observation group received nasogastric tube placement and jejunal nutrition tube placement, and the patients in the control group received general gastroscope and placed gastric tube and jejunal nutrition tube through mouth. Success rate of catheterization, catheter pain score, satisfaction score, vital signs, completion time of catheterization, and complication were collected.

RESULTS

the fluctuation of vital signs in control group was significantly higher than that in observation group. There was statistical significance between two groups in vital signs after intervention (P<0.05), mainly manifested in the heart rate, breathing and pulse pressure difference. On the other hand, there was no statistical significance between two groups in pulse oxygen after nursing intervention (P>0.05). The catheter pain score is obviously improved in the observation group compared with control group after intervention. The improvement score of satisfaction in the observation group was 91.47±7.65 points, and that in the control group was 83.64±5.24 points. The completion time of catheterization was improved in the observation group compared with control group. There was statistical significance between two groups in satisfaction score and completion time of catheterization (P<0.05). The rate of abdominal distention and diarrhea in the control group was higher than that in the observation group (P<0.05).

CONCLUSION

Nasoscopically assisted nasogastri tube and nasojejunal tube placement has the advantages of simple and fast, short operation time, high success rate and few complications. It is the first choice of intubation method for enteral nutrition support treatment.

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.

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.

Migration of Feeding Tubes Assessed by Using an Electromagnetic Device: A Cohort Study

BACKGROUND

Bedside methods to verify placement of a feeding tube are not accurate for detecting placement within the gastrointestinal tract, increasing risk of pulmonary aspiration. Current guidelines recommend verifying placement every 4 hours, yet the rationale for this recommendation is unknown.

OBJECTIVE

To assess spontaneous migration of small-bore feeding tubes in critically ill adults.

METHODS

A prospective, repeated-measures cohort study was performed in 2 intensive care units. An electromagnetic placement device was used to assess distal feeding tube location every 24 hours for 7 days. Tube migration between zones-esophageal, gastric, and postpyloric- was considered clinically significant.

RESULTS

Feeding tubes were analyzed in 20 patients. Interrater agreement was substantial for round 2 of a blinded analysis of insertion tracings (g = 0.78); 100% agreement was achieved after unblinding. Among 62 outcomes (migration assessments), 4 feeding tubes migrated 8 times (3 forward and 5 retrograde). All migrations occurred in the postpyloric zone and none were clinically significant. Within 24 hours of insertion, 50% of feeding tubes had migrated forward. Repeated-measures analysis showed a greater likelihood of migration in patients with an endotracheal tube (relative risk, 3.46 [95% CI, 1.14-10.53]; P = .03).

CONCLUSIONS

No tubes migrated retrograde into the stomach or esophagus, challenging the practice of verifying placement every 4 hours. Verification every 24 hours may be adequate if migration is not suspected. Also, lack of visible anatomical structures on insertion tracings from an electromagnetic placement device make subtle changes in postpyloric placement difficult to identify accurately.

Simo decoction versus domperidone suspension for post-pyloric spiral nasoenteric tube placement: A multicenter, randomized, non-inferiority trial

BACKGROUND & AIMS

Leveraging prokinetics to facilitate trans-pyloric migration is a conventional strategy. However, due to restrictions on the use of domperidone suspension, oral prokinetics is relatively modest. The study aims to assess the effectiveness of simo decoction as an alternative to domperidone suspension in facilitating post-pyloric placement of spiral nasoenteric tubes.

METHODS

A prospective, open-label, parallel, and non-inferiority randomized controlled trial was performed involving critically ill adults in 6 university hospitals in China between September 2017 and May 2019. Patients were randomly assigned to receive either simo decoction 20 ml q8h, or domperidone suspension 20 mg/20 ml q6h for 24 h. The primary outcome was procedure success defined as post-pyloric placement (spiral nasoenteric tubes reached the first portion of the duodenum or beyond confirmed by abdominal X-ray 24 h after tube insertion).

RESULTS

Of 268 patients assessed for eligibility, 224 patients were enrolled and randomly assigned to the simo decoction group or the domperidone suspension group (n = 112 per group). The success rate of post-pyloric placement was 41.1% (46/112) in the simo decoction group, as compared with 47.3% (53/112) in the domperidone suspension group (a risk difference of -6.3%, 95% CI, -19.2% to 6.7%, adjusted risk difference -3.7%, 95% CI -16.3% to 9.0%), in the intention-to-treat analysis, crossing the prespecified margin of -10% for non-inferiority. There were no differences between groups in the success rates of post-D1 (reaching the second portion of the duodenum or beyond), post-D2 (reaching the third portion of the duodenum or beyond), post-D3 (reaching the fourth portion of the duodenum or beyond) and proximal jejunum placement, the incidences of any adverse events, length of ICU stay or mortality in ICU.

CONCLUSIONS

Non-inferiority of simo decoction to domperidone suspension was not confirmed in facilitating post-pyloric placement of spiral nasoenteric tubes. Registration: The trial was registered with the Chinese Clinical Trial Registry at http://www.chictr.org.cn (registration number ChiCTR-INR-17011311).

Placement of a Jejunal Feeding Tube via an Ultrasound-Guided Antral Progressive Water Injection Method

Background

Jejunal feeding tube allows the nutrition of critical care patients more easy and safe. However, its placement remains a challenge. This study aimed to introduce a jejunal feeding tube through an ultrasound-guided antral progressive water injection method and subsequently to examine its efficacy.

Methods

Between April 2016 and April 2017, 54 patients hospitalized in the Department of Critical Care Medicine, Peking Union Medical College Hospital, China who needed nutritional support through a jejunal feeding tube were recruited for this study. Patients who applied ultrasound-guided antral progressive water injection method were classified into the experimental group. Patients who applied conventional method were registered as control group.

Results

No significant differences were found in age, body mass index, and Acute Physiology and Chronic Health Evaluation score, but a significant difference in operation time was found between the experimental group and the control group. Of the 24 individuals in the control group, 17 displayed clear catheter sound shadows once the tube entered the esophagus. In comparison, of the 30 individuals in the experimental group, all harbored catheter sound shadows through the esophageal gas injection method. Subsequent observation revealed that in the control group (via ultrasonographic observation), 15 individuals underwent successful antral tube entry, for a success rate of 63%. In the experimental group (via antral progressive water injection), 27 individuals underwent successful antral tube entry, for a success rate of 90%. There was a significant difference between the success rates of the two groups (χ² = 5.834, P = 0.022).

Conclusion

The antral progressive water injection method for the placement of a jejunal feeding tube is more effective than the traditional ultrasonic placement method.

Erythromycin versus metoclopramide for post-pyloric spiral nasoenteric tube placement: a randomized non-inferiority trial

Purpose

To determine whether erythromycin is non-inferior to metoclopramide in facilitating post-pyloric placement of self-propelled spiral nasoenteric tubes (NETs) in critically ill patients.

Methods

A prospective, multicenter, open-label, parallel, and non-inferiority randomized controlled trial was conducted comparing erythromycin with metoclopramide in facilitating post-pyloric placement of spiral NETs in critically ill patients admitted to intensive care units (ICUs) of eight tertiary hospitals in China. The primary outcome was procedure success defined as post-pyloric placement (spiral NETs reached the first portion of the duodenum or beyond confirmed by abdominal radiography 24 h after tube insertion).

Results

A total of 5688 patients were admitted to the ICUs. Of these, in 355 patients there was a plan to insert a nasoenteric feeding tube, of whom 332 were randomized, with 167 patients assigned to the erythromycin group and 165 patients assigned to the metoclopramide group. The success rate of post-pyloric placement was 57.5% (96/167) in the erythromycin group, as compared with 50.3% (83/165) in the metoclopramide group (a difference of 7.2%, 95% CI − 3.5% to 17.9%), in the intention-to-treat analysis, not including the prespecified margin of − 10% for non-inferiority. The success rates of post-D1 (reaching the second portion of the duodenum or beyond), post-D2 (reaching the third portion of the duodenum or beyond), post-D3 (reaching the fourth portion of the duodenum or beyond), and proximal jejunum placement and the incidence of any adverse events were not significantly different between the groups.

Conclusions

Erythromycin is non-inferior to metoclopramide in facilitating post-pyloric placement of spiral NETs in critically ill patients. The success rates of post-D1, post-D2, post-D3, and proximal jejunum placement were not significantly different.

Practice Patterns and Utilization of Tube Feedings in Acute Pancreatitis Patients at a Large US Referral Center

OBJECTIVES

Clinical trials on tube feedings (TFs) have not been sufficiently powered to change practice patterns in acute pancreatitis (AP). We aimed to describe the use, duration, and resource utilization of TF in AP patients at an expert US center.

METHODS

Of 423 AP patients prospectively enrolled at the University of Pittsburgh Medical Center from 2004 to 2014, 139 (33%) received TF. Data on TF were assessed in 100 (72%) of 139 patients with complete data available.

RESULTS

Patients on TF were more likely to be male, be obese, have alcohol etiology, and have moderately severe (34% vs 19%) or severe AP (62% vs. 3%) (P < 0.05). Tube feedings were started after a median of 5 days (interquartile range, 3-8 days) from admission and were administered for a median of 39 days (interquartile range, 19-58 days). A nasojejunal route (95%) with an oligomeric formula (92%) was the preferred TF strategy. Feeding tube complications led to at least 1 endoscopic tube replacement in 42% of patients and to an unexpected health care visit in 29% of those discharged on TF (16/55 patients).

CONCLUSIONS

Tube feedings form an important component in the management of patients with moderately severe and severe AP. Further studies should define the optimal utilization of TF and ways to reduce TF-related complications.

Effect of enteral nutrition suspension on immune function in severe acute pancreatitis patients with intestinal bacterial translocation

AIM

To observe the effect of enteral nutrition suspension (TPF-DM) on the immune function of acute severe pancreatitis patients with intestinal flora translocation.

METHODS

One hundred and ten acute severe pancreatitis patients with intestinal flora translocation treated at Jiuli Songyuan District People's Liberation Army No.117 Hospital were randomly divided into either a control group or a TPF-DM group (n = 55 each). The control group was treated with conventional therapy, while the TPF-DM group were treated with TPF-DM. The levels of inflammatory indexes [white blood cell (WBC) and C-reactive protein (CRP)], biochemical indicators [albumin (ALB), amylase (AMY), and endothelin (ET)], and immune markers (IgG, IgM, and IgA) were recorded at admission, 7 and 14 d after treatment. Time to abdominal pain disappearance, hospitalization time, hospitalization costs, and mortality rate were also compared in the two groups.

RESULTS

At admission, there was no significant difference in the levels of WBC, CRP, ALB, AMY, ET, IgG, IgM, or IgA between the two groups (P > 0.05). At 7 d and 14 d after treatment, the WBC and CRP levels of the two groups showed a decreasing trend (P < 0.05). The WBC and CRP levels at 7 and 14 d after treatment were significantly lower in the TPF-DM group than in the control group (P < 0.05). At 7 d and 14 d after treatment, ALB showed a decreasing trend in both groups, and the AMY and ET levels showed a trend of increasing (P < 0.05). The ALB levels in the TPF-DM group were significantly higher than those in the control group at 7 d and 14 d after treatment, and the levels of AMY and ET were significantly lower than those in the control group (P < 0.05). There was no significant difference in the time to disappearance of abdominal pain, hospital stay, hospitalization costs, or mortality between the two groups (P > 0.05). At 7 d and 14 d after treatment, the levels of IgG, IgM, and IgA in both groups showed a trend of increase (P < 0.05), and the levels of IgG, IgM, and IgA at 7 and 14 d after treatment in the TPF-DM group were significantly higher than those in the control group (P < 0.05).

CONCLUSION

TPF-DM can effectively treat severe acute pancreatitis patients with intestinal bacterial translocation by improving their inflammatory status and immune function.

Blind bedside postpyloric placement of spiral tube as rescue therapy in critically ill patients: a prospective, tricentric, observational study

Background

Various special techniques for blind bedside transpyloric tube placement have been introduced into clinical practice. However, transpyloric spiral tube placement facilitated by a blind bedside method has not yet been reported. The objective of this prospective study was to evaluate the safety and efficiency of blind bedside postpyloric placement of a spiral tube as a rescue therapy subsequent to failed spontaneous transpyloric migration in critically ill patients.

Methods

This prospective, tricentric, observational study was conducted in the intensive care units (ICUs) of three tertiary hospitals. A total of 127 consecutive patients with failed spontaneous transpyloric spiral tube migration despite using prokinetic agents and still required enteral nutrition for more than 3 days were included. The spiral tube was inserted postpylorically using the blind bedside technique. All patients received metoclopramide intravenously prior to tube insertion. The exact tube tip position was determined by radiography. The primary efficacy endpoint was the success rate of postpyloric spiral tube placement. Secondary efficacy endpoints were success rate of a spiral tube placed in the third portion of the duodenum (D3) or beyond, success rate of placement in the proximal jejunum, time to insertion, length of insertion, and number of attempts. Safety endpoints were metoclopramide-related and major adverse tube-associated events.

Results

In 81.9% of patients, the spiral feeding tubes were placed postpylorically; of these, 55.1% were placed in D3 or beyond and 33.9% were placed in the proximal jejunum, with a median time to insertion of 14 min and an average number of attempts of 1.4. The mean length of insertion was 95.6 cm. The adverse event incidence was 26.0%, and no serious adverse event was observed.

Conclusions

Blind bedside postpyloric placement of a spiral tube, as a rescue therapy subsequent to failed spontaneous transpyloric migration in critically ill patients, is safe and effective. This technique may facilitate the early initiation of postpyloric feeding in the ICU.
