Efficacy and safety of a modified method for blind bedside placement of post-pyloric feeding tube: a prospective preliminary clinical trial

Procedures for a Transpyloric Feeding Tube Inserted Into Newborns and Infants: A Systematic Review

BACKGROUND

Enteral feeding by a transpyloric tube in critically ill infants is indicated when there is a failure in gastric feeding. However, there is a wide variability regarding the insertion technique.

PURPOSE

To perform a systematic review of the methods for inserting a transpyloric feeding tube in newborns and infants.

DATA SOURCES

Nine databases, without date or language restrictions, accessed in September 2021.

STUDY SELECTION

A systematic review of experimental and nonexperimental studies, according to the "Patient/problem; Intervention; Comparison; Outcome" strategy and the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The clinical question was about the measurement and insertion techniques, as well as the success rates of properly placing a transpyloric tube in newborns and infants.

DATA EXTRACTION

Two authors (N.M.Q. and J.F.S.) analyzed 6 observational descriptive prospective studies, all of them published in peer-reviewed indexed medical journals and one in the official journal of the National Association of Neonatal Nurses.

RESULTS

The success rate varied between 70% and 100%. There was an important variability in the type of tube, measurement method, and insertion techniques. It was found that the most common strategies to achieve proper positioning were glabella-calcaneal measurements, gastric air insufflation, and right lateral decubitus.

IMPLICATIONS FOR PRACTICE

A transpyloric catheter insertion protocol needs to be established in each neonatal unit, according to the literature findings.

IMPLICATIONS FOR RESEARCH

Randomized controlled studies that evaluate the gastric air insufflation technique and other adjuvant measures could elucidate the knowledge gap concerning the correct positioning of transpyloric tubing in newborns and infants.

Application of visual placement of a nasojejunal indwelling feeding tube in intensive care unit patients receiving mechanical ventilation

Background

Compared with nasogastric nutrition, nasojejunal nutrition may prevent some complications of critically ill patients by maintaining better nutritional status, and blind placement of nasojejunal dwelling feeding tubes is widely used. However, the visual placement seems to be safer and more effective than the blind placement, and is still seldom reported.

Objective

We tried to develop visual placement of a nasojejunal feeding tube in intensive care unit patients.

Methods

A total of 122 patients receiving mechanical ventilation were admitted to the Department of Critical Care Medicine of the Fifth Affiliated Hospital of Wenzhou Medical University and received the placement of nasojejunal feeding tubes. These patients were randomly and evenly assigned into two groups, one group receiving visual placement of nasojejunal dwelling feeding tubes and another group receiving blind placement. Actual tube placement was confirmed by X-ray. The primary outcome included the success rates of first placement of feeding tubes. The secondary outcome included the time of tube placement, complications, the total cost, heart rates and respiratory rates.

Results

The primary outcome showed that the success rates of first placement were 96.70% (59 cases/61 cases) in the visual placement group, and two cases failed due to pyloric stenosis and gastroparesis. The success rates were 83.6% (51 cases/61 cases) in the blind placement group and 10 cases failed due to either wrong placement or retrograde tube migration. The success rates in the visual placement group were higher than that in the blind placement group (P = 0.015). The secondary outcome showed that the time of tube placement in the visual placement group was shorter than that in the blind placement group (P < 0.0001). The cost of tube placement in the visual placement group was higher than that in the blind placement group (P < 0.0001). The statistical differences in complications, heart and respiratory rates were insignificant between the two groups (P > 0.05).

Conclusion

Compared with the blind placement, the visual placement shortened the time of nasojejunal tube placement and increased success rates of first placement. The visual placement was more efficient, easy to operate, safe, and has potential clinical applications.

Risk factors for pneumonia in hospitalized older people with femoral fractures: Results from a Brazilian prospective cohort

BACKGROUND

Pneumonia is a common complication in older people who are hospitalized to treat different fractures, which increases morbimortality in this population.

OBJECTIVES

Estimating the pneumonia incidence density in older people hospitalized to treat femoral fractures and identifying risk factors for this infection.

METHODS

Prospective cohort study whose data were collected from a population of older people who were being treated for femoral fractures at a hospital in the central region of Brazil between September 2016 and February 2017. The pneumonia diagnosis was based on radiography and clinical tests. Incidence density was estimated according to gender, age, Charlson comorbidity index, polypharmacy, chronic pulmonary disease, admission to the intensive care unit, surgical treatment, and nasoenteral tube feeding. Magnitude of the associations was estimated by multiple Poisson regression.

RESULTS

Among the 200 patients, the pneumonia incidence density was 13.04/1,000 person-days. For men and older people 80 years old or older, the pneumonia incidence density was 15.6/1,000 person-days and 18.3/1,000 person-days, respectively. After adjusting for age, gender, chronic pulmonary disease, and admission to the intensive care unit, use of nasoenteral tubes remained associated with occurrence of pneumonia in older people, and the risk of developing the infection was eight times higher in the population who received nasoenteral feeding than that calculated for the population that did not use the devices (p ≤ 0.001).

CONCLUSION

Using nasoenteral tubes during hospital stays increased the risk of developing pneumonia in hospitalized older people, which reinforces the need for continuous care monitoring regarding use of tubes to prevent complications.
