Rehabilitative intervention for successful decannulation in adult patients with acquired brain injury and tracheostomy: a systematic review

PURPOSE

Tracheostomy and dysphagia are independently associated with increased complications and poorer functional outcome after acquired brain injury (ABI). The aim of this study was to identify and evaluate rehabilitation to restore functional swallowing ability and respiratory capacity during tracheal tube weaning.

MATERIALS AND METHODS

The review was conducted according to PRISMA guidelines. Any study design with adult patients with ABI and tracheostomy was eligible. The primary outcome was decannulation.

RESULTS

A total of 2647 records were identified and eight papers included. Four studies investigated pharyngeal electrical stimulation (PES), two explored Facial Oral Tract Therapy (F.O.T.T.), one respiratory physiotherapy (RPT), and one study investigated external subglottic air flow (ESAF). Two RCTs found a significant difference between intervention and control on successful decannulation and readiness for decannulation in favour of PES. Time from rehabilitation admission and tracheostomy to decannulation was significantly reduced after implementing an F.O.T.T.-based protocol.

CONCLUSION

Four interventions were identified, PES, F.O.T.T., RPT, and ESAF, all aimed at increasing oropharyngeal sensory input through stimulation. Due to heterogeneity of interventions, designs and outcome measures, effect could not be estimated. This review highlights the limited research on rehabilitative interventions and thus the limited evidence to guide clinical rehabilitation.

A Simplified Protocol for Tracheostomy Decannulation in Patients Weaned off Prolonged Mechanical Ventilation

Introduction  The criteria for the removal of the tracheostomy tube (decannulation) vary from center to center. Some perform an endoscopic evaluation under anesthesia or computed tomography, which adds to the cost and discomfort. We use a simple two-part protocol to determine the eligibility and carry out the decannulation: part I consists of airway and swallowing assessment through an office-based flexible laryngotracheoscopy, and part II involves a tracheostomy capping trial. Objective  The primary objective was to determine the safety and efficacy of the simplified decannulation protocol followed at our center among the patients who were weaned off the mechanical ventilator and exhibited good swallowing function clinically. Methods  Of the patients considered for decannulation between November 1st, 2018, and October 31st, 2020, those who had undergone tracheostomy for prolonged mechanical ventilation were included. The efficacy to predict successful decannulation was calculated by the decannulation rate among patients who had been deemed eligible for decannulation in part I of the protocol, and the safety profile was defined by the protocol's ability to correctly predict the chances of risk-free decannulation among those submitted to part II of the protocol. Results  Among the 48 patients included (mean age: 46.5 years; male-to-female ratio: 3:1), the efficacy of our protocol in predicting the successful decannulation was of 87.5%, and it was was safe or reliable in 95.45%. Also, in our cohort, the decannulation success and the duration of tracheotomy dependence were significantly affected by the neurological status of the patients. Conclusion  The decannulation protocol consisting of office-based flexible laryngotracheoscopy and capping trial of the tracheostomy tube can safely and effectively aid the decannulation process.

Best Practice Recommendations for Dysphagia Management in Intensive Care Unit (ICU): A Delphi Study from Multidisciplinary Experts in Turkey

There is no study about all aspects of oropharyngoesophageal (OPE) dysphagia from diagnosis to follow-up in a multidisciplinary manner in the world. In order to close this gap, we aimed to create a recommendation study that can be used in clinical practice, addressing all aspects of dysphagia in the ICU in detail with the opinion of experienced multidisciplinary experts. This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-modified Delphi round via e-mail. Firstly, 15 open-ended questions were created, and then detailed recommendations including general principles, management, diagnosis, rehabilitation, and follow-up were created with the answers from these questions, Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation), and divergent consensus (not recommended).In the first Delphi round, a questionnaire consisting of 413 items evaluated with a scale of 0-10 was prepared from the opinions and suggestions given to 15 open-ended questions. In the second Delphi round, 55.4% were accepted and revised suggestions were created. At the end of the third Delphi round, the revised suggestion form was approved again and the final proposals containing 133 items were created. This study includes comprehensive and detailed recommendations, including a broad perspective from diagnosis to treatment and follow-up, as detailed as possible, for management of dysphagia in patients with both oropharyngeal- and esophageal-dysphagia in ICU.

Cough flows as a criterion for decannulation of autonomously breathing patients with tracheostomy tubes

BACKGROUND

Adequate cough or exsufflation flow can indicate an option for safe tracheostomy decannulation to noninvasive management. Cough peak flow via the upper airways with the tube capped is an outcome predictor for decannulation readiness in patients with neuromuscular impairment. However, this threshold value is typically measured with tracheotomy tube removed, which is not acceptable culturally in China. The aim of this study was to assess the feasibility and safety of using cough flow measured with tracheostomy tube and speaking valve (CFSV) > 100 L/min as a cutoff value for decannulation.

STUDY DESIGN

Prospective observational study conducted between January 2019 and September 2022 in a tertiary rehabilitation hospital.

METHODS

Patients with prolonged tracheostomy tube placement were referred for screening. Each patient was assessed using a standardized tracheostomy decannulation protocol, in which CFSV greater than 100 L/min indicated that the patients' cough ability was sufficient for decannulation. Patients whose CFSV matched the threshold value and other protocol criteria were decannulated, and the reintubation and mortality rates were followed-up for 6 months.

RESULTS

A total of 218 patients were screened and 193 patients were included. A total of 105 patients underwent decannulation, 103 patients were decannulated successfully, and 2 patients decannulated failure, required reinsertion of the tracheostomy tube within 48 h (failure rate 1.9%). Three patients required reinsertion or translaryngeal intubation within 6 months.

CONCLUSIONS

CFSV greater than 100 L/min could be a reliable threshold value for successful decannulation in patients with various primary diseases with a tracheostomy tube.

TRIAL REGISTRATION

This observational study was not registered online.

Development and Effect Evaluation of an Action-Oriented Interdisciplinary Weaning Protocol for Cuffed Tracheostomy Tubes in Patients with Acquired Brain Injury

The objective was to develop an interdisciplinary weaning protocol (IWP) for patients with tracheostomy tubes due to acquired brain injury, and to effect evaluate implementation of the IWP on decannulation rates and weaning duration. An expert panel completed a literature review in 2018 to identify essential criteria in the weaning process. Based on consensus and availability in clinical practice, criteria for guiding the weaning process were included in the protocol. Using the IWP, dysphagia is graded as either severe, moderate, or mild. The weaning process is guided through a protocol which specified the daily duration of cuff deflation until decannulation, along with recommendations for treatment and rehabilitation interventions. Data from 337 patient records (161 before and 176 after implementation) were included for effect evaluation. Decannulation rate during hospitalization was unchanged at 91% vs. 90% before and after implementation (decannulation rate at 60 days was 68% vs. 74%). After implementation, the weaning duration had decreased compared to before implementation, hazard ratio 1.309 (95%CI: 1.013; 1.693), without any increased risk of tube-reinsertion or pneumonia. Furthermore, a tendency toward decreased length of stay was seen with median 102 days (IQR: 73-138) and median 90 days (IQR: 58-119) (p = 0.061) before and after implementation, respectively. Scientific debate on weaning protocols for tracheostomy tubes are encouraged.

Predictive Factors for Successful Decannulation in Patients with Tracheostomies and Brain Injuries: A Systematic Review

Neurological patients frequently have disorders of consciousness, swallowing disorders, or neurological states that are incompatible with extubation. Therefore, they frequently require tracheostomies during their stay in an intensive care unit. After the acute phase, tracheostomy weaning and decannulation are generally expected to promote rehabilitation. However, few reliable predictive factors (PFs) for decannulation have been identified in this patient population. We sought to identify PFs that may be used during tracheostomy weaning and decannulation in patients with brain injuries. We conducted a systematic review of the literature regarding potential PFs for decannulation; searches were performed on 16 March 2021 and 1 June 2022. The following databases were searched: MEDLINE, EMBASE, CINAHL, Scopus, Web of Science, PEDro, OPENGREY, OPENSIGLE, Science Direct, CLINICAL TRIALS and CENTRAL. We searched for all article types, except systematic reviews, meta-analyses, abstracts, and position articles. Retrieved articles were published in English or French, with no date restriction. In total, 1433 articles were identified; 26 of these were eligible for inclusion in the review. PFs for successful decannulation in patients with acquired brain injuries (ABIs) included high neurological status, traumatic brain injuries rather than stroke or anoxic brain lesions, younger age, effective swallowing, an effective cough, and the absence of pulmonary infections. Secondary PFs included early tracheostomy, supratentorial lesions, the absence of critical illness polyneuropathy/myopathy, and the absence of tracheal lesions. To our knowledge, this is the first systematic review to identify PFs for decannulation in patients with ABIs. These PFs may be used by clinicians during tracheostomy weaning.

Highlights from the Respiratory Failure and Mechanical Ventilation 2022 Conference

The Respiratory Intensive Care Assembly of the European Respiratory Society gathered in Berlin to organise the second Respiratory Failure and Mechanical Ventilation Conference in June 2022. The conference covered several key points of acute and chronic respiratory failure in adults. During the 3-day conference, ventilatory strategies, patient selection, diagnostic approaches, treatment and health-related quality of life topics were addressed by a panel of international experts. Lectures delivered during the event have been summarised by Early Career Members of the Assembly and take-home messages highlighted.

Evaluation of Factors Determining Tracheostomy Decannulation Failure Rate in Adults: An Indian Perspective Descriptive Study

Decannulation is an essential step in liberating tracheostomised patients from mechanical ventilation. This procedure is purely based on the clinician's judgment and there is no universally accepted protocol to date for this vital procedure. This study aimed to describe decannulation practice and failure rates in patients with tracheostomy and to determine the factors associated with the outcome of tube removal. A prospective study was done on 50 patients (both sexes) who required a tracheostomy and cared for at Command Hospital Bangalore Center between January 2019 and April 2020. Data were analyzed using descriptive and inferential tests. Out of the 50 decannulation decisions, 7 patients experienced decannulation failures giving a failure rate of 14%. Out of the 7 decannulation failure cases, about 4 patients (10%) experienced difficulty in swallowing and 3 patients (2%) experienced stridor. There was no associated mortality. A decannulation failure of 14% was seen in this study in tracheostomised patients after prolonged mechanical ventilation. Various factors govern the success of tracheostomy decannulation procedures which occur during the first 24-48 h after decannulation. Lack of swallowing/secretions/cough management and the development of stridor were the commonest cause of decannulation failure in this study.

How the work of respiratory physiotherapists changes the tracheostomy management and decannulation in a NICU department: an Italian experience

Tracheotomy is a clinical procedure that is often necessary though not without complications, hence the need for appropriate and timely decannulation. The inclusion of trained respiratory physiotherapists (RPT) in the staff and the use of shared protocols could help the team to manage the patient with tracheotomy cannula. The objective of this study was to describe the difference in the rate of decannulation and clinical outcomes of tracheostomized patients admitted to a NeuroIntensive Care Unit (NICU) team after the inclusion of a group of physiotherapists specialized in respiratory physiotherapy and a new phoniatric protocol. It is a 6-year retrospective study, in which two periods of 3 years each were compared: in the first period (P1: September 2013-August 2016) physiotherapists were called to treat NICU patients on a consultative basis (2 hours/day for 5 days a week); in the second period (P2: September 2016-August 2019) two full-time respiratory physiotherapists were present on the ward (7 hours/day, 6/7 days/week). In P2 period, a decannulation protocol was used. Patients who had undergone a tracheotomy procedure and who were alive at the time of discharge were retrospectively evaluated. We described the number of decannulations, the length of stay in NICU and decannulation time; the diagnosis of decannulated patients and the number of deaths. 928 total patients were analysed: 468 in P1, 460 in P2. Total length of stay or number of deaths did not change significantly between the two periods, while the number of decannulated patients before the discharge was higher in P2 143 (64%), compared with P1 79 (36%) p<0.001. More patients with neurological pathologies involving possible swallowing disorders, such as cerebral haemorrhage, head trauma and stroke, have been successfully decannulated in P2 than in P1 (120 patients in P2 vs 54 in P1). A multidisciplinary approach, including respiratory physiotherapist, dedicated to tracheostomy management, decannulation and early mobilization in NICU is safe, feasible and seems to improve the number of severe patients decannulated, even if no change was observed in NICU length of stay or deaths. Further studies must confirm our results in other ICU settings.

Outcomes of prolonged mechanical ventilation and tracheostomy in critically ill elderly patients: a historical cohort study

PURPOSE

With an aging global population, the increased proportion of elderly patients in the intensive care unit (ICU) raises important questions regarding optimal management. Currently, data on tracheostomy and its outcomes in the elderly are limited. We aimed to determine the in-hospital survival of elderly ICU patients following tracheostomy, and describe impacts on discharge disposition and functional outcomes.

METHODS

We conducted a historical cohort study at two academic hospitals in Toronto. All patients aged ≥ 70 yr who received a tracheostomy during their ICU stay between January 2010 and June 2016 were included in a retrospective chart review. Data on patient demographics, frailty, tracheostomy indication, and outcomes were collected.

RESULTS

The study included 270 patients with a mean (standard deviation) age of 81 (6) yr. The majority were admitted to ICU for respiratory failure (147/270, 54%) and received a tracheostomy for prolonged mechanical ventilation (202/270, 75%). Intensive care unit and hospital mortality were 26% (68/270) and 46% (125/270), respectively. Twenty-five percent (67/270) of patients were decannulated during hospital admission, a median [interquartile range (IQR)] of 41 [25-68] days after tracheostomy. Intensive care unit and hospital length of stay were 31 [17-53] and 81 [46-121] days, respectively. At hospital discharge, 6% (17/270) of patients were discharged home, all were frail (median Clinical Frailty Score of 7) and most were tube-fed (101/270, 70%), unable to speak (81/270, 56%), and nonambulatory (98/270, 68%).

CONCLUSIONS

In patients aged ≥ 70 yr, tracheostomy during ICU stay marked a transition toward prolonged chronic critical illness. Nearly half of the patients died during the admission, and although a quarter were successfully decannulated, the majority of survivors were left with severe frailty and functional impairment.

Feasibility of face mask spirometry during decannulation in head and neck surgery: prospective cohort study

OBJECTIVES

To analyze the relationship between spirometric parameters measured with a face mask versus a mouthpiece, as well as the feasibility of face mask spirometric evaluation in a head and neck surgery (HNS) decannulation context. Furthermore, we examine peak inspiratory flow (PIF) cut-off values before and after decannulation.

DESIGN

Prospective cohort study.

SETTING

Otolaryngology HNS Department of a University teaching hospital.

PARTICIPANTS

Twenty-four patients were selected. A maximal flow-volume loop was conducted before (with mouthpiece) and after (with mouthpiece and face mask) decannulation.

MAIN OUTCOME MEASURES

Recorded outcomes were forced vital capacity (FVC), forced expiratory volume in the first second, peak expiratory flow, PIF, forced expiratory flow at 50% of FVC and forced inspiratory flow at 50% of FVC. Spearman correlation coefficients between spirometric parameters measured with a face mask versus a mouthpiece were calculated. Wilcoxon test was used to check differences between mouthpiece and face mask values.

RESULTS

Correlation between mouthpiece and face mask spirometric values was moderate to high (r = 0.46 to 0.95). All parameters measured by spirometry were significantly lower with a face mask than those obtained with a mouthpiece (p < 0.05). Before decannulation, the lowest PIF value (tested with mouthpiece) that allowed successful decannulation was 1 L/s. After decannulation, the lowest PIF value tested with mouthpiece and face mask for successful completion of the decannulation process were 0.77 and 0.56 L/s, respectively.

CONCLUSION

Face mask is a feasible option to perform a spirometry when face diseases hinder spirometric evaluation through a mouthpiece in an HNC surgery context.

Professional qualification of Brazilian Speech-Language Pathologists and its impacts on the Blue Dye Test (BDT)

PURPOSE

To characterize the professional profile of Speech Pathologists working in health services in Brazil and to verify if the time length of professional practice, specialized formation and experience in dysphagia contribute to the more adequate interpretation and application of the Blue Dye Test (BDT).

METHODS

Through social medias and class entities, speech pathologists from all over Brazil were contacted by e-mail, that provided them a link from which they could access the online quiz, containing questions about the professional profile and the application of the BDT. The responses were categorized dichotomously according to the most robust scientific researches on the BDT and were compared statistically according to time length of professional practice, specialized formation and experience in dysphagia.

RESULTS

145 speech pathologists participated, 91.7% of them females. Most work in hospitals, have 11 to 15 years of profession (27.6%), and working from 1 to 5 years in the area of dysphagia (32.4%). Professionals with lato sensu training (54.3%) and with more than a decade of profession (58.1%) showed greater adequacy in interpreting the positive result of BDT.

CONCLUSION

The present study reinforces the important role of specialized training in dysphagia in addition to continuing health educational practices in determining the excellence of clinical speech therapy, especially with tracheostomized patients after intubation and at risk of bronchoaspiration.

Diagnosis and treatment of neurogenic dysphagia - S1 guideline of the German Society of Neurology

Introduction

Neurogenic dysphagia defines swallowing disorders caused by diseases of the central and peripheral nervous system, neuromuscular transmission, or muscles. Neurogenic dysphagia is one of the most common and at the same time most dangerous symptoms of many neurological diseases. Its most important sequelae include aspiration pneumonia, malnutrition and dehydration, and affected patients more often require long-term care and are exposed to an increased mortality. Based on a systematic pubmed research of related original papers, review articles, international guidelines and surveys about the diagnostics and treatment of neurogenic dysphagia, a consensus process was initiated, which included dysphagia experts from 27 medical societies.

Recommendations

This guideline consists of 53 recommendations covering in its first part the whole diagnostic spectrum from the dysphagia specific medical history, initial dysphagia screening and clinical assessment, to more refined instrumental procedures, such as flexible endoscopic evaluation of swallowing, the videofluoroscopic swallowing study and high-resolution manometry. In addition, specific clinical scenarios are captured, among others the management of patients with nasogastric and tracheotomy tubes. The second part of this guideline is dedicated to the treatment of neurogenic dysphagia. Apart from dietary interventions and behavioral swallowing treatment, interventions to improve oral hygiene, pharmacological treatment options, different modalities of neurostimulation as well as minimally invasive and surgical therapies are dealt with.

Conclusions

The diagnosis and treatment of neurogenic dysphagia is challenging and requires a joined effort of different medical professions. While the evidence supporting the implementation of dysphagia screening is rather convincing, further trials are needed to improve the quality of evidence for more refined methods of dysphagia diagnostics and, in particular, the different treatment options of neurogenic dysphagia. The present article is an abridged and translated version of the guideline recently published online (https://www.awmf.org/uploads/tx_szleitlinien/030-111l_Neurogene-Dysphagie_2020-05.pdf).

Interventional pulmonology during COVID-19 pandemic: current evidence and future perspectives

COVID-19, caused by SARS-CoV-2 infection, has become increasingly prevalent worldwide, reaching a pandemic stage in March 2020. The organization of health care services had to change because of this new disease, with the need to reallocate staff and materials, besides changing management protocols. A very important challenge is not to expose patients and health care workers to the risk of infection and not to waste personal protective equipment (PPE). In the field of interventional pulmonology, various aspects related to COVID-19 must be taken into great consideration. Although bronchoscopy is not a first-line test for patients with suspected SARS-CoV-2 infection, it has a role in selected cases and it can be useful for differential diagnosis. However, bronchoscopy is an aerosol-generating procedure, that’s why its unjustified use could contribute to propagate the virus. For this reason, the utility of each procedure must be carefully evaluated, the patient has to be properly investigated before the procedure, which has to be performed with specific precautions, including adequate PPE. In this review, we summarize the knowledge and the principal statements about endoscopic activity in COVID-19 period, in both diagnosis of COVID-19 and management of patients. How to safely perform both bronchoscopic and pleural-related procedures (thoracoscopy, pleural biopsy and drainage of pleural effusions) is described with the aim to help the staff to decide when and how performing a procedure. We also highlight how interventional pulmonology could help in matter of complications related to COVID-19.

Intubation-Related Laryngeal Pathology Precluding Tracheostomy Decannulation: Incidence and Associated Risk Factors

OBJECTIVES

To identify the incidence and risk factors for intubation-related laryngeal lesions that preclude tracheostomy decannulation in a large population.

METHODS

A 3-year retrospective case-control study was performed of tracheotomized adults in acute rehabilitation facilities who underwent routine endoscopic evaluation of the airway as part of the facilities' decannulation protocol. Patients with known upper airway pathology, external laryngeal trauma, cricothyrotomy or emergent tracheostomy, prior head and neck radiation, isolated tracheal lesions, and patients with incomplete reports were excluded. The laryngeal pathologies were classified, and demographics and clinical features were compared between those whose lesions precluded decannulation and all other patients.

RESULTS

Three hundred seventy-one patients met inclusion criteria. One hundred six (28.6%) had laryngotracheal lesions. Forty-nine patients (13.2%) had intubation-related lesions of the larynx that precluded decannulation. These lesions included posterior glottic stenosis (30.6%), granulation tissue (24.5%), vocal fold immobility (16.3%), subglottic stenosis (16.3%), a combination of granulation tissue and stenosis (10.2%), and glottic edema (2.0%). A BMI ≥ 25 kg/m² was associated with laryngeal lesions precluding decannulation. There was no difference in age, sex, race, diabetes mellitus, endotracheal tube size, number of days intubated, and number of intubations between groups. Seventy-eight percent of patients with lesions precluding decannulation were decannulated after medical or surgical therapy. The decannulation rate of patients without lesions precluding decannulation was 79.9%.

CONCLUSIONS

BMI ≥ 25 kg/m² may increase the risk of development of laryngeal lesions preventing decannulation. Given that 13.2% of tracheotomized patients have laryngeal lesions precluding decannulation, an endoscopic evaluation of the airway is important to prevent decannulation failure and future airway symptoms.
