Videofluoroscopy of swallowing in symptomatic patients who have undergone long-term intubation

Prevalence and evaluation of oropharyngeal dysphagia in patients with severe acute respiratory syndrome coronavirus 2 infection in the intensive care unit

Objective

The main objective was to assess the prevalence of dysphagia in the intensive care unit in patients with coronavirus disease 2019.

Methods. A cohort, observational, retrospective study was conducted of patients admitted to the intensive care unit for severe acute respiratory syndrome coronavirus 2 pneumonia at the University Hospital of Rouen in France.

Results

Over 4 months, 58 patients were intubated and ventilated, 43 of whom were evaluated. Screening revealed post-extubation dysphagia in 62.7 per cent of patients. In univariate analysis, a significant association was found between the presence of dysphagia and: the severity of the initial pathology, the duration of intubation, the duration of curare use, the degree of muscle weakness and the severity indicated on the initial scan. At the end of intensive care unit treatment, 22 per cent of the dysphagic patients had a normal diet, 56 per cent had an adapted diet and 22 per cent still received exclusive tube feeding.

Conclusion

Post-extubation dysphagia is frequent and needs to be investigated.

The incidence and clinical outcomes of postextubation dysphagia in a regional critical care setting

BACKGROUND

Postextubation dysphagia (PED) has been shown to occur in 41% of critically ill patients requiring endotracheal intubation. With one-third of patients with PED experiencing silent aspiration, it is reasonable to anticipate negative health outcomes are likely, although this has not yet been systematically explored in an Australian context.

OBJECTIVES

The aim of the study was to determine the impact of PED, in a regional Australian intensive care unit (ICU), on rates of pneumonia, the length of stay in the ICU and hospital, and healthcare expenditure.

METHODS

This study was conducted as a retrospective cohort analysis, which used administrative healthcare data of patients who received endotracheal intubation for invasive mechanical ventilation. Patients with a tracheostomy or known pre-existing dysphagia were excluded.

RESULTS

A total of 822 patient episodes were identified, of which 7% (n = 58) presented with PED. Half of all patients within the PED cohort (53%) were intubated for fewer than 48 h. Patients with PED had a longer median length of stay in the ICU (5 days versus 3 days, p < 0.001) and were more likely to develop pneumonia (odds ratio = 2.51, 95% confidence interval = 1.28, 4.95) than extubated patients without dysphagia. Median cost per hospital admission for patients with PED was double that for extubated patients without dysphagia (AUD $42,685 versus AUD $20,840, p < 0.001).

CONCLUSIONS

This study highlights that even a short duration of intubation may carry a risk of PED. The presence of PED, regardless of duration of intubation, increased the rates of pneumonia, length of stay in the ICU and hospital, and healthcare expenditure.

Prevalence, Pathophysiology, Diagnostic Modalities, and Treatment Options for Dysphagia in Critically Ill Patients

Postextubation dysphagia may impose a substantial burden on intensive care unit patients and healthcare systems. Approximately 517,000 patients survive mechanical ventilation during critical care annually. Reports of postextubation dysphagia prevalence are highly variable ranging between 3% and 93%. Of great concern is aspiration leading to the development of aspiration pneumonia when patients resume oral feeding. Screening for aspiration with a water swallow test has been reported to be positive for 12% of patients in the intensive care unit after extubation. This review aims to increase awareness of postextubation dysphagia and provide an updated overview of the current knowledge regarding prevalence, pathophysiology, diagnostic modalities, and treatment options.

Dysphagia in older persons following severe burns: Burn location is irrelevant to risk of dysphagia and its complications in patients over 75 years

BACKGROUND

Management of burns in older persons is complex with evidence indicating advanced age is associated with elevated risk for morbidity and mortality. Dysphagia and its sequelae may further increase this risk.

AIMS

(1) Determine the prevalence, and (2) identify risk factors for dysphagia in patients admitted with severe burn injury over 75 years.

METHODS

All patients >75 years admitted to Concord Repatriation General Hospital with severe burn injury over a 4-year period (2013-2017) were assessed for dysphagia on presentation and continually monitored throughout their admission. Burn injury, demographic and nutritional data were captured and analysed for association with and predictive value for dysphagia.

RESULTS

Sixty-six patients (35 male; 31 female) aged 75-96 years (median 82 years) were recruited. Dysphagia was identified in 46.97% during their hospital admission. Dysphagia was significantly associated with burn size, pre-existing cognitive impairment, mechanical ventilation, duration of enteral feeding, hospital length of stay, in-hospital complications and mortality. No association was identified between burn location, burn mechanism, surgery and dysphagia. Burn size and Malnutrition Screening Tool score were found to be independent predictors for dysphagia.

CONCLUSIONS

Dysphagia prevalence is high in older persons with burns and is associated with increased morbidity and mortality, regardless of burn location.

Botulinum Toxin Injection in the Treatment of Postextubation Dysphagia: A Case Report

Prolonged intubation is known to bring on postextubation dysphagia (PED) in some patients. We have noted that there were some studies to investigate specific type and pattern of PED, which showed large variety of different swallowing abnormalities as mechanisms of PED that are multifactorial. There are several options of treatment in accordance with the management of these abnormalities. A botulinum toxin (BoT) injection into the upper esophageal sphincter (UES) can improve swallowing functions for patients with this disorder, by working to help the muscle relax. In this case, the conventional treatment was not effective in patients with PED, whereas the BoT injection made a great improvement for these patients. This study suggests that the UES pathology could be the main cause of PED.

Intensive swallowing and orofacial contracture rehabilitation after severe burn: A pilot study and literature review

BACKGROUND

Dysphagia following severe burns can be significant and protracted, yet there is little evidence describing the rehabilitation principles, process or outcomes.

PURPOSE

Outline current evidence and detail the clinical outcomes of two cases who underwent a multifaceted intensive treatment programme aimed at rehabilitating dysphagia by strengthening swallow function and minimising orofacial contractures after severe head and neck burns.

METHODS

Two men (54 and 18 years) with full-thickness head and neck burns and inhalation injury underwent intensive orofacial scar management and dysphagia rehabilitation. Therapy was prescribed, consisting of scar stretching, splinting and pharyngeal swallow tasks. Horizontal and vertical range of movement (HROM; VROM), physiological swallow features, functional swallowing outcomes and related distress, were collected at baseline and routinely until dysphagia resolution and scar stabilisation.

RESULTS

At presentation, both cases demonstrated severely reduced HROM and VROM, profound dysphagia and moderate dysphagia related distress. Therapy adherence was high. Resolution of dysphagia to full oral diet, nil physiological swallowing impairment, and nil dysphagia related distress was achieved by 222 and 77 days post injury respectively. VROM and HROM achieved normal range by 237 and 204 days.

CONCLUSION

Active rehabilitation achieved full functional outcomes for swallowing and orofacial range of movement. A protracted duration of therapy can be anticipated in this complex population.

[Oral feeding of long-term ventilated patients with a tracheotomy tube. Underestimated danger of dysphagia]

BACKGROUND

In long-term mechanically ventilated patients, dysphagia is a common and potentially life-threatening complication, which can lead to aspiration and pneumonia. Nevertheless, many intensive care unit (ICU) patients are fed by mouth without evaluation of their deglutition capability.

OBJECTIVE

The goal of this work was to evaluate the prevalence of aspiration due to swallowing disorders in long-term ventilated patients who were fed orally in the ICU while having a blocked tracheotomy tube.

METHODS

In all, 43 patients participated-each underwent a fiberoptic investigation of deglutition on the day of admission to the rehabilitation clinic.

RESULTS

A total of 65 % of the patients aspirated, 71 % of these silently. There were no associations between aspiration and any of the following: gender, indication for mechanical ventilation (underlying disease) or the duration of intubation and ventilation by tracheotomy tube. However, the association between aspiration and age was statistically significant (p = 0.041). Aspirating patients were older (arithmetic mean = 70 years, median = 74 years) than patients who did not aspirate (arithmetic mean = 66 years, median = 67 years).

CONCLUSION

Intubation and add-on tracheotomies can lead to potentially life-threatening swallowing disorders that cause aspiration, independent of the underlying disease. Before feeding long-term mechanically ventilated patients by mouth, their ability to swallow needs to be investigated using fiberoptic endoscopic evaluation of swallowing (FEES) or a saliva dye test, if a cuff deflation and the use of a speaking valve are possible during spontaneous respiration.

Clinical prognostic indicators of dysphagia following prolonged orotracheal intubation in ICU patients

Introduction

The development of postextubation swallowing dysfunction is well documented in the literature with high prevalence in most studies. However, there are relatively few studies with specific outcomes that focus on the follow-up of these patients until hospital discharge. The purpose of our study was to determine prognostic indicators of dysphagia in ICU patients submitted to prolonged orotracheal intubation (OTI).

Methods

We conducted a retrospective, observational cohort study from 2010 to 2012 of all patients over 18 years of age admitted to a university hospital ICU who were submitted to prolonged OTI and subsequently received a bedside swallow evaluation (BSE) by a speech pathologist. The prognostic factors analyzed included dysphagia severity rate at the initial swallowing assessment and at hospital discharge, age, time to initiate oral feeding, amount of individual treatment, number of orotracheal intubations, intubation time and length of hospital stay.

Results

After we excluded patients with neurologic diseases, tracheostomy, esophageal dysphagia and those who were submitted to surgical procedures involving the head and neck, our study sample size was 148 patients. The logistic regression model was used to examine the relationships between independent variables. In the univariate analyses, we found that statistically significant prognostic indicators of dysphagia included dysphagia severity rate at the initial swallowing assessment, time to initiate oral feeding and amount of individual treatment. In the multivariate analysis, we found that dysphagia severity rate at the initial swallowing assessment remained associated with good treatment outcomes.

Conclusions

Studies of prognostic indicators in different populations with dysphagia can contribute to the design of more effective procedures when evaluating, treating, and monitoring individuals with this type of disorder. Additionally, this study stresses the importance of the initial assessment ratings.

Avaliação clínica da deglutição em unidade de terapia intensiva

OBJETIVO: Relatar os resultados da avaliação clínica completa da deglutição em pacientes críticos de um hospital de ensino de grande porte na cidade de São Paulo. MÉTODOS: Foi realizado um estudo prospectivo, descritivo, no período de setembro a novembro de 2009, em uma unidade de terapia intensiva de emergências clínicas de trinta leitos, de um hospital terciário de grande porte do Brasil. Foram encaminhados 35 pacientes para a avaliação fonoaudiológica clínica da deglutição. Para a avaliação clínica completa da deglutição na unidade de terapia intensiva, foram preconizados os seguintes protocolos: Protocolo de Avaliação Preliminar (PAP), Protocolo de Avaliação do Risco para Disfagia (PARD) e Protocolo de Introdução e Transição da Alimentação por Via Oral (PITA). RESULTADOS: Neste estudo, foi constatada uma prevalência de 63% de disfagia orofaríngea (DO) na UTI, sendo a maioria destas classificadas como moderada e moderada-grave (39%). Entre os pacientes encaminhados para avaliação da deglutição, 74% apresentaram intubação orotraqueal prévia. A análise estatística revelou as variáveis que poderiam classificar corretamente os pacientes como tendo ou não DO nos testes clínicos. Esses indicadores clínicos incluíram: força da tosse, coordenação pneumofonoarticulatória, gravidade da disfonia e elevação laríngea. Vinte e seis pacientes (74%) completaram todos os protocolos. Desse total, 38% retornaram à dieta regular. CONCLUSÃO: A prática com protocolos padronizados mostra-se como uma importante opção no gerenciamento da disfagia orofaríngea na unidade de terapia intensiva.

Diagnostic accuracy of bedside swallow evaluation versus videofluoroscopy to assess dysphagia in individuals with tetraplegia

OBJECTIVE

To assess the accuracy of bedside swallow evaluation (BSE) compared with videofluorosopic swallow study (VFSS) in diagnosing dysphagia in individuals with tetraplegia due to spinal cord injury (SCI).

DESIGN

A prospective diagnostic accuracy study according to STAndards for the Reporting of Diagnostic accuracy studies (STARD) criteria.

SETTING

A county hospital with acute inpatient SCI unit.

PATIENTS

Thirty-nine subjects with SCI and tetraplegia were enrolled. All of the subjects underwent BSE, and 26 subjects completed the VFSS.

METHODS

Individuals with SCI underwent a BSE followed by a VFSS within 72 hours of the BSE. The subjects were diagnosed as having dysphagia if they had positive findings in either BSE or VFSS.

MAIN OUTCOME MEASURES

Sensitivity, specificity, and positive and negative predictive values were calculated by using VFSS as the criterion standard.

RESULTS

Fifteen subjects (38%) were diagnosed as having dysphagia based on the BSE results. Among the subjects who completed the VFSS, 11 were diagnosed with dysphagia (42%) and 4 were diagnosed with aspiration (10%). Of the 26 subjects who completed both BSE and VFSS, only 1 subject was diagnosed differently compared with BSE (3.8%). Different diet recommendations were made in 4 cases after VFSS versus BSE. Different liquid recommendations were made in 8 cases after VFSS versus BSE. Sensitivity of BSE was 100% (95% confidence interval [CI], 71.5%-100%), specificity was 93.3% (95% CI, 68.1%-99.8%). A positive predictive value of BSE was 91.7% (95% CI, 61.5%-100%), and the negative predictive value was 100% (95% CI, 76.8%-100%).

CONCLUSIONS

Dysphagia is present in approximately 38% of individuals with acute tetraplegia. Because only one of the 21 subjects was diagnosed differently based on VFSS, we believe that BSE is an appropriate screening tool for dysphagia for individuals with cervical SCI. However, VFSS provided additional information on diet and liquid recommendations, so there appears to be an important clinical role for the VFSS.

The incidence of dysphagia following endotracheal intubation: a systematic review

Hospitalized patients are often at increased risk for oropharyngeal dysphagia following prolonged endotracheal intubation. Although reported incidence can be high, it varies widely. We conducted a systematic review to determine: (1) the incidence of dysphagia following endotracheal intubation, (2) the association between dysphagia and intubation time, and (3) patient characteristics associated with dysphagia. Fourteen electronic databases were searched, using keywords dysphagia, deglutition disorders, and intubation, along with manual searching of journals and grey literature. Two reviewers, blinded to each other, selected and reviewed articles at all stages according to our inclusion criteria: adult participants who underwent intubation and clinical assessment for dysphagia. Exclusion criteria were case series (n < 10), dysphagia determined by patient report, patients with tracheostomies, esophageal dysphagia, and/or diagnoses known to cause dysphagia. Critical appraisal used the Cochrane risk of bias assessment and Grading of Recommendations, Assessment, Development and Evaluation tools. A total of 1,489 citations were identified, of which 288 articles were reviewed and 14 met inclusion criteria. The studies were heterogeneous in design, swallowing assessment, and study outcome; therefore, we present findings descriptively. Dysphagia frequency ranged from 3% to 62% and intubation duration from 124.8 to 346.6 mean hours. The highest dysphagia frequencies (62%, 56%, and 51%) occurred following prolonged intubation and included patients across all diagnostic subtypes. All studies were limited by design and risk of bias. Overall quality of the evidence was very low. This review highlights the poor available evidence for dysphagia following intubation and hence the need for high-quality prospective trials.

[Management of oropharyngeal dysphagia. Current status]

The diagnostics and therapy of oropharyngeal dysphagia fall within the competence of ENT, phoniatrics and speech language pathology. Due to etiologic diversity, interdisciplinary management is necessary in many cases. After taking a thorough history, focused on swallowing, dynamic instrumental examination methods, i.e. videoendoscopic and videofluoroscopic swallowing studies, allow an evaluation of the morphology and function of the act of swallowing. Videoendoscopic swallowing studies enable the ENT specialist/phoniatrician to decide on further diagnostic steps, to establish a therapy and to recommend the type of feeding (oral, non-oral). Therefore, in clinical routine, knowledge of the diagnostics and therapy of swallowing disorders is indispensable for the ENT specialist/phoniatrician.

Removal of the tracheostomy tube in the aspirating spinal cord-injured patient

STUDY DESIGN

Four related case reports, occurring within a 10-month time frame during 2001.

OBJECTIVES

Aspiration is commonly reported in the literature as a contraindication to decannulation. We report four examples of successful removal of the tracheostomy tube in the presence of aspiration by an experienced team, utilising a risk management approach.

SETTING

Victorian Spinal Cord Service (VSCS), Austin Hospital, Melbourne, Australia.

METHODS

Four individuals in our unit with traumatic spinal cord injury, three quadriplegic and one paraplegic, presented with aspiration identified by a positive modified Evan's blue dye test or constant coughing, gagging and oxygen desaturation during cuff deflation trials. In three of the four cases, the tracheostomy tube had been in situ for a prolonged period and the patients had failed to progress towards decannulation. A decision was made to decannulate these four patients in spite of the presence of traditionally held contraindications for decannulation. The multidisciplinary team carefully compared the inherent risks of premature decannulation against those of prolonged tracheostomisation. Given the risk associated with this procedure, a closely monitored decannulation protocol was instituted.

RESULTS

All four patients were successfully decannulated with improved quality of life, eating between 1 and 4 days and communicating immediately after decannulation. None experienced respiratory deterioration.

CONCLUSION

It is possible to safely decannulate aspirating spinal cord injured individuals in some instances, using a risk management approach.

Videofluoroscopy of swallowing abnormalities in 22 symptomatic patients after cardiovascular surgery

OBJECTIVE

The aim of this study was to evaluate the types of swallowing abnormalities that occur in symptomatic patients who have undergone cardiovascular surgery.

MATERIALS AND METHODS

From 1994 to 2001, 22 patients (17 males and five females; age range, 4-89 years; mean age, 64 years) who had swallowing abnormalities after cardiovascular surgery were referred for a videofluoroscopic swallowing study. Each study was analyzed for functional abnormalities of the tongue, soft palate, epiglottis, hyoid and larynx, pharynx, upper esophageal sphincter, and esophagus. Also, the performance of transesophageal echocardiography, long-term intubation, or both was noted.

RESULTS

Swallowing abnormalities were present in 18 patients (81.8%) (range, one to eight functional abnormalities; mean, 3.9 functional abnormalities). The distribution of abnormalities across the functional units statistically significantly deviated (chi(2) = 14.4; df = 6; p = 0.025) from uniform distribution, with abnormalities most commonly involving the hyoid and larynx (13 patients [59.1%]) and the pharynx (10 patients [45.5%]). Aspiration was found in 13 patients (59.1%) (predeglutitive, n = 1; intradeglutitive, n = 4; postdeglutitive, n = 3; and mixed, n = 5). In the 14 patients (63.6%) who underwent transesophageal echocardiography, long-term intubation, or both, we frequently found incomplete tilting of the epiglottis, pharyngeal weakness, and postdeglutitive aspiration.

CONCLUSION

Most patients with swallowing problems after cardiovascular surgery present with multiple abnormalities that most commonly affect the hyoid and larynx and the pharynx and result predominantly in intra- or postdeglutitive aspiration. The performance of transesophageal echocardiography and long-term intubation may influence the types of swallowing abnormalities.
