Tracheostomy Cuff Herniation following Cardiac and Pulmonary Arrest

Tracheostomy is a common procedure performed on patients who require long-term airway maintenance and ventilation support. It is preferred over endotracheal intubation due to its reduced airway resistance, lower risk of displacement compared with the endotracheal tube, increased patient comfort, improved weaning from mechanical ventilation, and enhanced suction capabilities. According to the literature, patients needing airway support for fewer than 12 days can undergo translaryngeal intubation, while tracheostomy is indicated for patients requiring ventilatory support for more than 20 days. Although tracheostomy is frequently performed in ICUs and operating rooms, several complications can arise following the procedure. These complications include leakage, obstruction of the tracheal tube, minor or major bleeding or oozing, barotrauma, infections, tracheoesophageal fistula, stenosis, and injury to surrounding peripheral tissues such as arteries, veins, and nerves.1 While herniation of the endotracheal cuff is a more common cause of airway obstruction and hypoxia, tracheostomy tube cuff herniation is a rare complication of this procedure.1-7 In this report, we present a rare case of cardiopulmonary arrest following the implantation of a tracheostomy tube cuff in a female patient and its management.

Tracheal Stenosis After Intubation and Tracheostomy in Patients Admitted to Intensive Care Units: A Case-Control Study

Background: One of the most dangerous complications after endotracheal intubation or tracheostomy is tracheal stenosis. Objectives: This study aimed to determine the personal and clinical characteristics of tracheal stenosis following intubation or tracheostomy in intensive care unit patients. Methods: This is a nested case-control study. Thirty-five patients who suffered from tracheal stenosis from March 2016 to March 2021 and had been intubated and tracheostomized in intensive care units (ICU) were selected for the case group. The control group included 105 patients intubated and tracheostomized in ICU during the same period without tracheal stenosis. A demographic and clinical characteristics questionnaire was used to collect data from the patients' medical records. Results: The mean length of intubation (P < 0.001), endotracheal and tracheostomy tube cuff pressure (P < 0.001), chronic obstructive pulmonary disease (COPD) (P = 0.043), intubation history (P = 0.045), and airway management (P < 0.001) showed significant differences between the case and control groups. The logistic regression model revealed that COPD (OR = 8.519, P = 0.037), intubation history (OR = 3.939, P = 0.013), length of intubation (OR = 1.118, P = 0.003), age (OR = 0.960, P = 0.030), and endotracheal and tracheostomy tube cuff pressure (OR = 1.988, P < 0.001) were associated with tracheal stenosis. The time interval between intubation/tracheostomy ranged from approximately 28 to 938 days. Conclusions: Given the impact of certain care practices during hospitalization on the occurrence of tracheal stenosis, such as the mean length of intubation, endotracheal and tracheostomy tube cuff pressure, and airway management, it is recommended that standardized training on these interventions be prioritized for staff in intensive care departments. Additionally, attention must be given to specific patient characteristics, such as age, COPD, and history of intubation.

Impact of Volume-Oriented Incentive Spirometry on Lung Volume and Peak Expiratory Flow Rate in Patients With Tracheostomy.

Background The volume-oriented incentive spirometer is a specialized device designed to facilitate maximal inspiration, promote deep breathing exercises, and enhance lung function. The use of spirometry is challenging and not proven in patients with tracheostomy. Therefore, this study aimed to assess the impact of volume-oriented incentive spirometry on lung volume and peak expiratory flow rate (PEFR) in patients with tracheostomy. Methodology All adult patients with cuffed tracheostomy tubes with a Medical Research Council (MRC) score of more than 48 were studied. Volume-oriented incentive spirometry was performed and the PEFR was measured before and after the spirometry session. All patients underwent 28 sessions in seven days with initial few training sessions. Patient demographic information, such as age, gender, reasons for tracheostomy, MRC at the beginning of the session, volume (volume per breath, mL), and PEFR, was documented. Results Thirty patients were studied, consisting of 18 males and 12 females with initial MRC scores ranging from 48 to 60. The mean lung volume and mean PEFR at the end of seven days were 950 ± 330.9and 134.7 ± 63.3, respectively, demonstrating safety with minimal complications, including four cases of pain at the tracheostomy site, three cases of hypotension, one case of abdominal pain, and 22 cases with no reported complications. Conclusion Volume-oriented incentive spirometry improves lung volumeand PEFRin patients with a tracheostomy tube. Additionally, spirometry proved to be both feasible and effective in this patient population.

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.

Over-Inflating a Tracheostomy Tube Cuff for Tracheo-Innominate Artery Fistula.

We report an angiographic image of a 58-year-old woman with profuse bleeding from a tracheo-innominate artery fistula. It may not have been possible to obtain this valuable image if adequate initial resuscitation and an over-inflated tracheostomy tube cuff had not been administered to stop bleeding during an emergency.

Factors involved in the one‐year changes in the tracheal diameter of patients with amyotrophic lateral sclerosis undergoing tracheostomy positive pressure ventilation

AbstractBackgroundTracheostomy positive pressure ventilation (TPPV) is associated with complications in patients with amyotrophic lateral sclerosis (ALS), particularly tracheostomy tube‐related problems.AimTo determine the frequency of patients with ALS who received TPPV that have tracheal enlargement and factors associated with changes in tracheal diameter.MethodsWe included 43 patients with ALS undergoing TPPV who were admitted at Sayama Neurological Hospital in October 2019. The tracheal diameter at the height of the tracheostomy tube cuff was measured radiographically at specific time points. Tidal volume, inspiratory maximum pressure (PIP), dynamic lung compliance (Cdyn), tracheostomy tube cuff data, and patient demographic information and data were also collected.ResultsThe frequency of tracheomegaly was 60.5% at the initial data collection. The differences in tracheal diameter between the first measurement, after 12 months, and between 3 and 12 months were significant. ΔTracheal diameter correlated with TPPV duration, PIP, Cdyn, ΔPIP, ΔCdyn, and tracheal diameter. Multiple regression analysis, with Δtracheal diameter as the objective variable and TPPV duration, Cdyn, and tracheal diameter as explanatory variables, revealed an adjusted R‐square value of 0.36.ConclusionTracheomegaly and more enlarged tracheal diameters over time were more frequently observed in patients with ALS receiving TPPV. Furthermore, the trachea dilates over time and the tracheal diameter was related to baseline TPPV time, Cdyn, and tracheal diameter. Patients with shorter baseline TPPV duration, higher baseline Cdyn, and smaller baseline tracheal diameter were more likely to have larger tracheal diameters. Therefore, early prevention is important.

Differences in residual volume above different tracheostomy tube cuffs depending on tube structure, tube tilt angle, and liquid viscosity

IntroductionProper management of aspirated material above the tracheostomy tube cuff is crucial to prevent complications, such as aspiration pneumonia. This study aimed to thoroughly examine the effects of aspirated liquid viscosity, suction port positioning, and tube tilt angle on residual volume above the cuff (RVAC).MethodsFive types of tracheostomy tubes (approximately 9 mm outer diameter) were placed through a transparent cylinder with an inner diameter of 18 mm. The cuff was inflated to completely seal the interior of the cylinder. Four liquids with different viscosities were poured onto the cuff, and the liquid above the cuff was suctioned from the side port. The cylinder was angled at 90° and 20°, and each test was performed thrice to determine the average RVAC.ResultsAfter side-port suctioning, some liquid residue was observed on the cuff of all tracheostomy tubes. The RVAC increased with higher liquid viscosity. The tubes with a longer distance from the suction port opening to the cuff top exhibited more RVAC. Moreover, the RVAC was almost the same regardless of the cylinder angle for tubes with a suction port on the lateral side. However, tubes with backside ports showed a decreased RVAC with cylinder tilt.ConclusionsThis study underscores the persistence of residual material on cuffed tracheostomy tubes even with regular subglottic secretion drainage. This emphasizes the need for specialized tracheostomy tube development aimed at reducing post-suction RVAC. Improved designs can potentially minimize complications associated with residue accumulation.

Subacute prognosis of oral nutrition (SPOON): Development of a multivariable prognostic model for complete oral intake in tube-fed subjects with acquired brain injury

Enteral feeding is very common following an acquired brain injury. However, no prognostic models for oral food intake have been developed for subacute rehabilitation. The aim of this study was to develop a prognostic model and online tool, coined "subacute prognosis of oral nutrition" (SPOON), for complete oral intake in tube-fed subjects with acquired brain injury. The model was developed using routinely gathered clinical data from a cohort of 1233 adult patients who were tube-fed at admission for sub-acute inpatient rehabilitation. Candidate predictors were included based on scientific evidence and their availability in the medical records within the first days following admission. The outcome was time until achieving complete oral food intake without any tube-feeding supplements. Time until complete oral intake was analyzed by discrete time-to-event analysis with logit-link and presented as daily odds ratios (OR) with 95% confidence intervals (CI). The following predictors of complete oral intake were included in the model: age, diagnosis, cuffed tracheostomy tube, days from injury to admission for rehabilitation, and the Early Functional Abilities (EFA) sum score. Multiple adjusted analyses were performed stratified by cuffed tracheostomy tube status. Some of the strongest predictors of complete oral intake were age 18-40 years, OR 1.99 (95%CI: 1.53; 2.59); 0-2 weeks since injury, OR 3.75 (95%CI: 2.72; 5.16); and EFA 61-100 (slight/no disturbance in function), OR 5.81 (95%CI: 4.47; 7.55). The online prognostic tool SPOON was evaluated in a usability study. Based on feedback from clinicians, the tool was further refined to enable extraction of data for prediction directly from medical records. The objective of SPOON is to complement the planning of rehabilitation initiatives and inform discussions to determine if a percutaneous endoscopic gastrostomy (PEG) tube should be inserted. SPOON is being implemented locally, but external validation based on appropriate data modeling is warranted before further clinical implementation.

Tracheoarterial fistula in a patient with amyotrophic lateral sclerosis successfully managed by overinflation of the tracheostomy tube cuff alone: a case report

BackgroundTracheoarterial fistula is the most devastating complication after tracheostomy, and its mortality, without definitive treatment, approaches 100%. In general, the combination of bedside emergency management, that is, overinflation of the tracheostomy tube cuff, and definitive treatment such as surgical or endovascular intervention is necessary to prevent the poor outcome. Patients with neuromuscular diseases such as amyotrophic lateral sclerosis are susceptible to tracheoarterial fistula because of long-term mechanical ventilation and muscle weakness.Case presentationWe describe a case of tracheoarterial fistula in a Japanese 39-year-old patient with amyotrophic lateral sclerosis with long-term ventilator management. The patient was clinically diagnosed with a tracheoarterial fistula because of massive bleeding following sentinel hemorrhage. The massive hemorrhage was controlled by overinflation of the tracheostomy tube cuff alone, without definitive treatment.ConclusionsThis case suggests overinflation of the tracheostomy tube cuff alone plays an important role, semi-permanently, in the management of tracheoarterial fistula, especially in cases where surgical or endovascular intervention is not indicated. Clinicians taking care of patients with tracheostomy undergoing long-term mechanical ventilation should be aware that tracheoarterial fistula might occur following tracheostomy.

Tracheal airway pressure in tracheostomy tube capping trials: an experimental study

BackgroundTracheostomy tube capping is a commonly used test to determine if the tracheostomy tube can be removed. The success of the capping trial depends on the patient’s ability to maintain sufficient spontaneous breathing with an occluded tracheostomy tube. The impact of an occluded tracheotomy tube on airway resistance is currently unknown. The aim of this study was to investigate tracheal pressure during capping or stoma button insertion and potential determinants concerning cuff.MethodsEight cuffed and uncuffed tracheostomy tubes and three stoma buttons of various manufacturers and sizes were inserted into the trachea model. Cuffs were completely deflated or contained atmospheric pressure. The trachea was ventilated bidirectional with a respirator in volume-controlled mode and volume flows 15–60 L/min. Tracheal pressure drop during inspiration as a parameter of pressure required to move gas through the airway was measured.ResultsTracheal pressure drops occurred linearly or irregularly during capping trials to a maximum of 4.2 kPa at flow rates of 60 L/min for atmospheric pressure cuffs. In tracheostomy tubes with completely deflated cuffs, pressure drop in the trachea reaches a maximum of 3.4 kPa at a flow rate of 60 L/min. For tracheostomy tubes with cuff smaller inner or outer diameters do not regularly result in lower tracheal pressure drop. The pressure drop varies between different tracheostomy tubes depending on the manufacturer. In cuffed tracheostomy tubes, we observed three phenomena: sail-like positioning, folding over, and tightening of the cuff during flow. The maximum tracheal pressure drop during stoma button insertion reaches 0.014 kPa.ConclusionsThe cuff is a central element for the pressure drop in the airway and thus airway resistance during spontaneous translaryngeal breathing with a capped TT. Complete deflation reduces the pressure drop in the trachea. Due to deformation of the cuff, measured pressures are irregular as the volume flow is increased. Incomplete deflated cuffs and material characteristics of tracheostomy tubes and cuffs in addition to anatomical and clinical variables may cause unsuccessful capping trials due to increased airway resistance. All stoma buttons showed that pressure drop and thus airway resistance due to stoma buttons has no clinical relevance.

Acquired Tracheomegaly in Critically Ill Patients With COVID-19: A Literature Review

Tracheomegaly is defined as an abnormally dilated trachea and is seen in patients requiring long-standing mechanical ventilation and/or significant hyperinflation of their endotracheal or tracheostomy tube cuffs can occur in adults with severe COVID-19. Tracheomegaly is linked with inadequate nutrition, pneumonia, diabetes, hypotension, steroids, and protracted mechanical ventilation, which are common in COVID-19 patients. Findings include cuff leaks that necessitate cuff overinflation to maintain adequate tidal volumes. Tracheomegaly can be diagnosed with chest radiographs, chest computed tomography, bronchoscopy, or diagnostic laryngoscopy or tracheoscopy. This condition leads to a concern for obstruction, airway collapse, aspiration pneumonia, and iatrogenic tracheal injuries.

Obstructive shock due to tracheal perforation following long-term placement of a tracheostomy tube in a pediatric patient: a case report

BackgroundTracheal perforation, although rare, is a known late complication of tracheostomy tube placement.Case presentationWe present a 7-year-old boy with severe physical and mental disabilities under tracheostomy and long-term mechanical ventilation and steroid therapy who suddenly developed obstructive shock secondary to pneumomediastinum and pneumothorax. Prior bronchoscopy had shown the tip of the tracheostomy tube contacting the posterior tracheal wall, causing ulceration and subsequent tracheal perforation. The perforation was bridged using a cuffed tracheostomy tube, but the patient subsequently died of additional comorbidities.ConclusionsOur experience suggests that tracheal perforation should be considered when pediatric patients with tracheostomy tubes suddenly develop hypotension.

Do tapered tracheostomy cuffs improve translaryngeal gas flow when compared to barrel cuffed fenestrated tubes: A laboratory study.

ObjectiveThe benefits of tracheostomy are well documented and include improved comfort and a reduction in sedative requirements that may facilitate more rapid ventilation weaning. A stable airway established with tracheostomy allows pulmonary toilet that may help in addressing aspiration. It is postulated that it may also increase translargyngeal airflow and allow phonation. We hypothesized that taper‐shaped cuffed tracheostomy tubes have less bulk upon cuff deflation, and on this basis, gas flow past the deflated tapered cuff is better than non‐tapered barrel cuffs and equal to gas flow in equivalent‐sized fenestrated versions.MethodsThis comparative bench study measured exhaled gas flow of Shiley™ Flexible taper‐cuffed tracheostomy and Fenestrated Shiley™ FEN tubes of equivalent sizes. Three sizes of Shiley™ tracheostomy tubes were used in printed 3D model tracheas, Jackson sizes 4, 6, and 10 (6.5, 7.5, and 10 mm ISO sizes). A standard ventilator provided tidal volumes to mechanical lungs. Because expiratory volume was the focus, the mechanical lungs exhaled through the model trachea and only the air exiting the model trachea, representing exhalation, was measured.ResultsAcross three sizes, the Shiley™ Flexible tracheostomy tube allowed significantly more translaryngeal airflow compared to the tracheostomy tube with fenestrations.ConclusionThis bench study showed significantly improved air flow past the cuff compared to fenestrated tubes. Improved airflow may help the phonation ability of patients. Clinical studies are required to elucidate use of this cuff design to allow phonation in patients with a tracheostomy.Level of evidence: NA.

Inner Lumen Tracheostomy Tube Capable of Continuous Monitoring of Cuff Pressure.

Tracheostomy is one of the most important airway management procedures in patients with respiratory problems. This procedure might be the only option for patients with airway and respiratory problems, who are not able to have an appropriate ventilation and oxygenation. For this purpose, tracheostomy tubes are used with different applications. One of these types of tubes is the cuffed tracheostomy tube, used for fixation, positive pressure ventilation and aspiration prevention. Nevertheless, there are two common problems with using these regular tracheostomy tubes. First, these tracheostomy tubes do not have a unique cuff pressure monitoring system. Although there are portable monitoring devices for such purpose in intensive care units (ICU), they are shared among several patients, increasing the risk of infection transmission. Second, due to the presence of the patient’s thick secretions, the tracheostomy tube becomes obstructed and inefficient. The pathway does not get open even through suction and thus the tracheostomy tube must be replaced. In order to resolve these problems, the inner lumen tracheostomy tube capable of continuous monitoring of cuff pressure has been invented with two techniques, which set it apart from other related tools. The invented optimized tracheostomy tube has been developed with different techniques through creating a disposable monometer system attached to it as well as a removable inner lumen embedded in it.

Evaluating the biomechanical characteristics of cuffed-tracheostomy tubes using finite element analysis

The objective of this study was to perform finite element analysis (FEA) of cuff inflation within an anatomically accurate model of an adult trachea in four different cuffed-tracheostomy tube designs. The leakage quantified by the distance between the cuff and trachea was largest for the Tracoe cuff and smallest for the Portex cuff. The smooth muscle stresses were greatest for the Portex and least for the Distal cuff, respectively. The proposed FEA model offers a promising approach to virtually evaluate the sealing efficacy of cuffed-tracheostomy tubes and the tracheal wall stresses induced by cuff inflation, prior to application.

AARC Clinical Practice Guideline: Management of Pediatric Patients With Tracheostomy in the Acute Care Setting.

Children requiring a tracheostomy to maintain airway patency or to facilitate long-term mechanical ventilatory support require comprehensive care and committed, trained, direct caregivers to manage their complex needs safely. These guidelines were developed from a comprehensive review of the literature to provide guidance for the selection of the type of tracheostomy tube (cuffed vs uncuffed), use of communication devices, implementation of daily care bundles, timing of first tracheostomy change, type of humidification used (active vs passive), timing of oral feedings, care coordination, and routine cleaning. Cuffed tracheostomy tubes should only be used for positive-pressure ventilation or to prevent aspiration. Manufacturer guidelines should be followed for cuff management and tracheostomy tube hygiene. Daily care bundles, skin care, and the use of moisture-wicking materials reduce device-associated complications. Tracheostomy tubes may be safely changed at postoperative day 3, and they should be changed with some regularity (at a minimum of every 1-2 weeks) as well as on an as-needed basis, such as when an obstruction within the lumen occurs. Care coordination can reduce length of hospital and ICU stay. Published evidence is insufficient to support recommendations for a specific device to humidify the inspired gas, the use of a communication device, or timing for the initiation of feedings.

Application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal or hypopharyngeal cancer

Objective: To Investigate the application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal and hypopharyngeal cancer. Methods: A total of 60 patients with laryngeal and hypopharyngeal cancer occurred serious postoperative complications, including 31 cases of severe postoperative neck infection, 8 cases of dyspnea, 5 cases of massive hemorrhage and 16 cases of seriously intractable aspiration. The tracheal cannula with inner cannula and outer cuff was immediately worn on these patients and the cuff was inflated. Different treatments were carried out according to different complications. The outer cuffs were inflated for patients with severe neck infections to prevent a large amount of neck secretions inhaled to the trachea. Patients with dyspnea immediately received ventilator-assisted ventilation. For those with massive hemorrhage on the wound, doctors should prevent bleeding and stop bleeding under general anesthesia. Patients with severely coughing should perform eating training to prevent food aspiration. The inner cannula was regularly replaced once a month for all of these patients. Results: Through targeted treatment, the complications of 60 patients with cuffed tracheostomy tube with inner cannula were effectively controlled. After dressing change, the neck wounds of 31 patients with neck infection were shrunk or healed. Finally, all of the patients were replaced with metal tracheal tubes. Eight cases with dyspnea were rescued with the symptomatic and related special treatment, and finally replace by metal tracheal tube. Five cases with massive bleeding in the neck wound were successfully rescued and replaced with metal tracheal cannula. Thirteen patients among 16 cases with intractable aspiration were removed the tracheal cannula and other 3 cases of old and severely ill were replaced with metal tracheal cannula. Conclusions: The cuffed tracheostomy tube with inner cannula is of great value in the treatment of severe postoperative complications of laryngeal or hypopharyngeal cancer. It is strongly recommended that the operators should fully understand and use it reasonably after the operation of laryngeal or hypopharyngeal cancer.

Head and Neck Practice in the COVID-19 Pandemics Today: A Rapid Systematic Review.

Introduction Head and neck specialists and otorhinolaryngologists are greatly exposed to coronavirus disease 2019 (COVID-19) transmission in their everyday praxis. Many articles are being published regarding medical staff protection and patient management during the pandemic. Objective To provide an easy access to and a trustful review of the main aspects that have changed in the head and neck surgery and otorhinolaryngology practice due to the COVID-19 pandemic. Data Synthesis The search terms used were: ( head and neck or otorhinolaryngology or ORL or thyroid ) AND ( severe acute respiratory syndrome coronavirus 2 [ SARS-COV-2] or COVID-19 or CORONAVIRUS ). The results were limited to the year of 2020. Articles were read in English, Portuguese, French, German, and Spanish or translated from Chinese. All included articles were read by at least two authors. Thirty-five articles were included. Most articles suggest postponing elective surgeries, with exception to cancer surgeries, which should be evaluated separately. Twenty-five articles recommended some kind of screening prior to surgery, using polymerase chain reaction (PCR) tests and epidemiological data. Extra precautions, such as use of personal protective equipment (PPE), are suggested for both tracheostomies and endoscopies. Fifteen articles give recommendation on how to use telemedicine. Conclusion The use of PPE (N95 or powered air-purifying respirator [PAPR]) during procedures should be mandatory. Patients should be evaluated about their COVID-19 status before hospital admission. Cancer should be treated. Tracheostomy tube cuff should be inflated inside the tracheal incision. All COVID-19 precautions should be kept until there is a validated antiviral treatment or an available vaccine.

Feeding Disorders in Children With Tracheostomy Tubes.

We aimed to describe feeding dysfunction in a group of children with tracheostomy. Single-center, retrospective chart review of all children with a tracheostomy who were evaluated by our interdisciplinary feeding program. Demographic and diagnostic data, nutrition variables, acceptance of food consistencies, as well as 2 validated psychometric instruments for assessment of feeding dysfunction were analyzed. Thirteen tracheostomy-dependent children (5/13; 38% ventilator dependent) were evaluated at a median age of 51 months (interquartile range [IQR], 26-69). The majority of children (8/13; 62%) underwent evaluation after decannulation. Four children (30%) had a history of a cuffed tracheostomy tube. Eleven children (85%) used a speaking valve prior to decannulation, only 2 of whom started before initial discharge with a tracheostomy. Children with a tracheostomy had low-median weight- and height-for-age z-scores (-1.27 and -1.73, respectively), with normal-median body mass index (BMI)-for-age z-score (0.175). Children received 75% of feedings via tube feeding (IQR, 13%-97%). Compared with other children with feeding disorders, children with tracheostomy had delays in initial acceptance of most food textures and general diet, and the Mealtime Behavior Questionnaire showed significantly worse overall scores (P = .01), and the About Your Child's Eating survey showed significantly higher parental perception of resistance to eating (P = .0001). Requirement of enteral nutrition, poor oral-feeding skills, chronic malnutrition, and worse mealtime behaviors are associated with tracheostomy. A history of ventilator dependence, cuffed tracheostomy, and inpatient speaking valve-use were infrequently associated with interdisciplinary feeding-program evaluation.

Successful respiratory management of a Marshall-Smith syndrome patient with a tracheo-innominate artery fistula

BackgroundTracheo-innominate artery fistula (TIF) is a life-threatening complication of tracheostomy. We describe perioperative management for innominate artery transection in a case with TIF.Case presentationA 4-year-old Japanese female with Marshal-Smith syndrome presented for management of TIF. She underwent tracheostomy at the age of 3 months and an uncuffed tracheostomy tube was inserted. One month before admission to our hospital, intermittent tracheal bleeding, suggesting TIF, occurred. Although we considered to change to a cuffed endotracheal tube, craniofacial abnormality suggested difficult oral intubation, and there was a possibility of rebleeding. Finally, innominate artery transection was performed under total intravenous anesthesia without changing the tracheostomy tube. Surgery completed uneventfully and she received mechanical ventilation under sedation for a day, followed by weaning without complications.ConclusionsA cuffed tracheostomy tube should have been inserted before surgery for effective hemostasis against sudden bleeding from TIF even though conversion to oral intubation was difficult.
