Tracheotomy in the intensive care unit: Guidelines from a French expert panel: The French Intensive Care Society and the French Society of Anaesthesia and Intensive Care Medicine

Tracheostomy: update on why, when and how

PURPOSE OF REVIEW

The aim of this review is to summarize available data, including the most recent ones, to help develop the best possible strategy regarding the use of tracheostomy in ICU patients requiring prolonged mechanical ventilation or who experience loss of airway-protecting mechanisms.

RECENT FINDINGS

Tracheostomy facilitates the weaning process by reducing the patient's work of breathing and increasing comfort. It thus allows for a reduction in sedation levels. It also helps with secretions clearance, facilitates disconnection from the ventilator, and enables earlier phonation, oral intake, and mobilization. Despite these advantages, tracheostomy does not reduce mortality and is associated with both early and late complications, particularly tracheal stenosis. The timing of tracheostomy remains a subject of debate, and only a personalized approach that considers each patient's specific characteristics can help find the best possible compromise between avoiding unnecessary delays and minimizing the risks of performing a needless invasive procedure. In the absence of contraindications, the percutaneous single dilator technique under fibroscopic guidance should be the first choice, but only if the team is properly trained.

SUMMARY

A step-by-step individualized approach based on the available evidence allows identifying the best strategy regarding the use of tracheostomy in ICU patients.

High-Riding Innominate Artery: Booby Trap for ICU Tracheotomy

Despite tracheotomy being a routine procedure, it is not rare to encounter anatomic irregularities that can compromise its success. In this report, we describe a case in which a high riding innominate artery was identified within the surgical trajectory moments before incision, which ultimately necessitated airway securement using an alternative laryngological procedure.

Safety Analysis of Visual Percutaneous Tracheostomy in Neurocritical Care Patients with Anticoagulation and Antithrombosis

BACKGROUND

This study aims to evaluate the safety of visual percutaneous tracheostomy (vPDT) in neurologic intensive care unit (NICU) patients who are under anticoagulant and antithrombotic therapy.

METHODS

A retrospective cohort study was conducted on 54 NICU patients who underwent vPDT at Tai'an Central Hospital from September 2022 to September 2023. The cohort included 36 men and 18 women aged 36-90 years (mean age 62.24 ± 12.24 years). Patients were divided into two groups based on their treatment: an anticoagulant and antithrombotic group (22 patients) and a non-anticoagulant and non-antithrombotic group (32 patients). Clinical data, including demographic information, comorbidities, Glasgow Coma Scale (GCS) score before vPDT, time from NICU admission to vPDT, laboratory indicators, and vPDT complications, were analyzed.

RESULTS

The incidence of vPDT complications in the anticoagulant and antithrombotic group was 18.2%, involving three cases of minor intraoperative bleeding and one case of posterior airway wall injury. The non-anticoagulant and non-antithrombotic group had an 18.8% complication rate, including four cases of minor intraoperative bleeding, one case of subcutaneous emphysema with local infection, and one unrelated death. No significant difference in vPDT complications was observed between the two groups (P > 0.05). However, the anticoagulant and antithrombotic group had a higher average age, higher GCS scores, and longer time intervals from NICU admission to vPDT and from intubation to vPDT (all P < 0.05).

CONCLUSION

vPDT appears to be a safe and feasible procedure for NICU patients receiving anticoagulant and antithrombotic therapy, with no significant increase in complications compared to those not on such therapies.

Impact of tracheostomy tube modalities on ventilatory mechanics: a bench study

PURPOSE

Tracheostomized patients often present with muscle weakness, altered consciousness, or swallowing difficulties. Hence, the literature is scarce regarding the challenging management of tracheostomy weaning. There is a need to strengthen the understanding of respiratory mechanisms with the different tracheostomy tube modalities that compose this weaning pathway. We aimed to evaluate the impact of these modalities on the work of breathing (WOB), total positive end-expiratory pressure (PEEPtot), and tidal volume (VT).

METHODS

With a three-dimensional (3D) printed head mimicking human upper airways, we added a tracheal extension, and pierced to allow insertion of a size 7.0 tracheostomy cannula. The whole was connected to an artificial lung. Three lung mechanics were simulated (normal, obstructive and restrictive). We compared five different tracheostomy tube modalities to a control scenario in which the tube was capped and the cuff was deflated.

RESULTS

A marginal difference was observed on the WOB within conditions with a slight increase + 0.004 [95% CI (0.003-0.004); p < 0.001] when the cuff was inflated in the normal and restrictive models and a slight decrease in the obstructive model. The highest PEEPtot that was reached was + 1 cmH2O [95% CI (1-1.1); p < 0.001] with high-flow therapy (HFT) with the cuff inflated in the obstructive model. We observed a statistically significant reduction in VT [up to - 57 mL 95% CI (- 60 to - 54); p < 0.001] when the cuff was inflated, in both the normal and obstructive models.

CONCLUSIONS

Our results support the use of conditions that involve cuff deflation. Intermediate modalities with the cuff deflated produced similar results than cannula capping.

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.

[Acute respiratory distress due to tracheostomy tube migration]

Tracheostomy cannula care is of paramount importance in the daily management of tracheotomized patients. While some complications are commonplace, specific events can occur, often according to type of cannula. We herein report the case of a 71-year-old patient; following a lengthy stay in the intensive care unit, she had received a Safe T-Tube cannula designed to provide support in a stenotic trachea. At home, while suctioning her tracheal secretions, she suddenly experienced respiratory distress requiring a rapid intervention. On arrival, no seeable cannula was found, either in the tracheostomy or in the patient's immediate surroundings. Following her transfer to intensive care, a new cannula was inserted into the tracheostomy opening, enabling mechanical ventilation to begin and achieving rapid relief of dyspnea and improvement of the patient's overall condition. Bronchial fibroscopy was then performed, during which the Safe T-Tube cannula was found folded on itself in a supra-carinal intra-tracheal position. It was extracted and replaced by a cannula of the same model, which was sewn to the skin. Although rare and usually limited to flexible cannulas, this complication is potentially fatal. Generally speaking, when cannula obstruction is suspected, bronchial endoscopy in an intensive care setting is a vital necessity. It is not only the cornerstone of the diagnosis, but also of paramount importance in treatment taking into full account the mechanism of obstruction.

Tracheostomy-Assisted Foreign Body Removal: Insights From a Case Series and Literature Review

BACKGROUND

Foreign body aspiration into the trachea is a common occurrence in children. While most foreign bodies in the airways can be removed using rigid tracheoscopy, there are instances where tracheostomy or tracheotomy is needed. This article presents a series of cases in which tracheostomy was necessary to remove foreign bodies, and summarizes the relevant experiences and lessons learned.

METHODS

We reviewed a total of 7 cases in which tracheostomy and rigid tracheoscopy were combined for foreign body removal out of a larger cohort of 1559 cases at Shenzhen Children's Hospital in Guangdong, China over a 20-year period.

RESULTS

The combined use of tracheostomy and rigid tracheoscopy resulted in successful removal of foreign bodies in all 7 patients reviewed in this study. Six patients developed complications of tracheotomy, mainly including mediastinal emphysema (5/7), subcutaneous emphysema (3/7), and pneumothorax (1/7). Tracheotomy was temporary in all patients.

CONCLUSION

In cases where a foreign body in the trachea is too large or has irregular, sharp edges, is embedded in submucosal tissues with edema, cannot be passed smoothly through the vocal cords, or local endoscopic facilities are inadequate, a tracheotomy may be necessary. However, this approach should be used with caution, and close collaboration with anesthesiologists and careful management of intraoperative emergencies are crucial for improving the success rate of the procedure. Additionally, the complications should be noted, paying particular attention to early complications such as pneumothorax, pneumomediastinum, and bleeding.

Flowchart for selecting an appropriate surgical airway in neurologically impaired pediatric intubated patients: a case series

OBJECTIVE

Medical advances have resulted in increased survival rates of neurologically impaired children who may require mechanical ventilation and subsequent tracheostomy as a surgical airway. However, at present, there is no definite consensus regarding the timing and methods for placement of a surgical airway in a neurologically impaired intubated child who needs to be cared for over a long-term period. We therefore created a flowchart for the selection of a surgical airway for Neurologically Impaired Pediatric Patients (NIPPs).

METHODS

The flowchart includes information on the patients' backgrounds, such as intubation period, prognosis related to reversibility, and history of aspiration pneumonia. To evaluate the importance of the flowchart, first we conducted a survey of pediatricians regarding selection of a surgical airway, and we also evaluated the appropriateness of the flowchart among pediatricians and caregivers through questionnaire surveys which include satisfaction with the decision-making process, and postoperative course after discharge.

RESULTS

A total of 21 NIPPs with intubation underwent surgery and a total of 24 participants (14 pediatricians and 10 caregivers) completed the survey. The answers regarding the importance of the flowchart showed that eleven pediatricians had experience selecting of surgical airways, nine of whom had had experiences in which they had to make a difficult decision. The answers regarding the appropriateness of the flowchart revealed that all pediatricians and caregivers were satisfied with the decision-making process and postoperative course after discharge using the flowchart.

CONCLUSIONS

The present study demonstrated the effectiveness of our flowchart for selecting an appropriate surgical airway in NIPP. By referring to our flowchart, pediatricians and caregivers are likely to be able to select an appropriate surgical airway, leading to increased satisfaction with the decision-making process and postoperative course.

Epidemiology of ventilator-associated pneumonia in ICU COVID-19 patients: an alarming high rate of multidrug-resistant bacteria

Background

COVID‑19 is a novel cause of acute respiratory distress syndrome (ARDS) that leads patients to intensive care unit (ICU) admission requiring invasive ventilation, who consequently are at risk of developing of ventilator‑associated pneumonia (VAP). The aim of this study was to assess the incidence, antimicrobial resistance, risk factors, and outcome of VAP in ICU COVID-19 patients in invasive mechanical ventilation (MV).

Methods

Observational prospective study including adult ICU admissions between January 1, 2021, and June 31, 2021, with confirmed COVID-19 diagnosis were recorded daily, including demographics, medical history, ICU clinical data, etiology of VAPs, and the outcome. The diagnosis of VAP was based on multi-criteria decision analysis which included a combination of radiological, clinical, and microbiological criteria in ICU patients in MV for at least 48 h.

Results

Two hundred eighty-four COVID-19 patients in MV were admitted in ICU. Ninety-four patients (33%) had VAP during the ICU stay, of which 85 had a single episode of VAP and 9 multiple episodes. The median time of onset of VAP from intubation were 8 days (IQR, 5–13). The overall incidence of VAP was of 13.48 episodes per 1000 days in MV. The main etiological agent was Pseudomonas aeruginosa (39.8% of all VAPs) followed by Klebsiella spp. (16.5%); of them, 41.4% and 17.6% were carbapenem resistant, respectively. Patients during the mechanical ventilation in orotracheal intubation (OTI) had a higher incidence than those in tracheostomy, 16.46 and 9.8 episodes per 1000-MV day, respectively. An increased risk of VAP was reported in patients receiving blood transfusion (OR 2.13, 95% CI 1.26–3.59, p = 0.005) or therapy with Tocilizumab/Sarilumab (OR 2.08, 95% CI 1.12–3.84, p = 0.02). The pronation and PaO₂/FiO₂ ratio at ICU admission were not significantly associated with the development of VAPs. Furthermore, VAP episodes did not increase the risk of death in ICU COVID-19 patients.

Conclusions

COVID-19 patients have a higher incidence of VAP compared to the general ICU population, but it is similar to that of ICU ARDS patients in the pre-COVID-19 period. Interleukin-6 inhibitors and blood transfusions may increase the risk of VAP. The widespread use of empirical antibiotics in these patients should be avoided to reduce the selecting pressure on the growth of multidrug-resistant bacteria by implementing infection control measures and antimicrobial stewardship programs even before ICU admission.

Clinical Proof of Concept for Stabilization of Tracheostomy Tubes Using Novel DYNAtraq Device

Introduction

Tracheostomy is one of the most common surgical strategies in intensive care units (ICU) and provides relevant clinical benefit for multiple indications. However, the complications associated with its use range from 5 to 40% according to different series. The risk of these complications could be reduced if fixation strategies and alignment of the tracheostomy tube with respect to the tracheal axis are improved.

Aim

To build a functional device of technological innovation in respiratory medicine for the fixation and alignment of tracheostomy cannula (acronym DYNAtraq) and to evaluate its feasibility and safety in a pilot study in mechanically ventilated patients.

Methods

Study carried out in four phases: (1) design engineering and functional prototyping of the device; (2) study of cytotoxicity and tolerance to the force of traction and push; (3) pilot study of feasibility and safety of its use in tracheostomized and mechanically ventilated patients; and (4) health workers satisfaction study.

Results

The design of the innovative DYNAtraq device included, on the one hand, a connector with very little additional dead space to be inserted between the cannula and the ventilation tubes, and, on the other hand, a shaft with two supports for adhesion to the skin of the thorax with very high tolerance (several kilograms) to pull and push. In patients, the device corrected the malpositioned tracheostomy tubes for the latero-lateral (p < 0.001) and cephalo-caudal angles (p < 0.001). Its effect was maintained throughout the follow-up time (p < 0.001). The use of DYNAtraq did not induce serious adverse events and showed a 70% protective effect for complications (RR = 0.3, p < 0.001) in patients.

Conclusion

DYNAtraq is a new device for respiratory medicine that allows the stabilization, alignment and fixation of tracheostomy tubes in mechanically ventilated patients. Its use provides additional benefits to traditional forms of support as it corrects misalignment and increases tolerance to habitual or forced movements. DYNAtraq is a safe element and can reduce the complications of tracheostomy tubes.

Utilization and outcomes of tracheostomies in the intensive care unit in Iceland in 2007-2020: A descriptive study

BACKGROUND

Tracheostomies are commonly utilized in ICU patients due to prolonged mechanical ventilation, upper airway obstruction, or surgery in the face/neck region. However, practices regarding the timing of placement and utilization vary. This study provides a nationwide overview of tracheostomy utilization and outcomes in the ICU over a 14-year period.

METHODS

A retrospective study including all patients that received a tracheostomy during their ICU stay in Iceland between 2007 and 2020. Data were retrieved from hospital records on admission cause, comorbidities, indication for tracheostomy insertion, duration of mechanical ventilation before and after tracheostomy placement, extubation attempts, complications, length of ICU and hospital stay and survival. Descriptive statistics were provided, and survival analysis was performed using Cox regression.

RESULTS

A total of 336 patients (median age 64 years, 33% females) received a tracheostomy during the study period. The most common indication for tracheostomy insertion was respiratory failure, followed by neurological disorders. The median duration of mechanical ventilation prior to tracheostomy insertion was 9 days and at least one extubation had been attempted in 35% of the cases. Percutaneous tracheostomies were 32%. The overall rate of complications was 25% and the most common short-term complication was bleeding (5%). In-hospital mortality was 33%. The one- and five-year survival rate was 60% and 44%, respectively.

CONCLUSIONS

We describe a whole-nation practice of tracheostomies. A notable finding is the relatively low rate of extubation attempts prior to tracheostomy insertion. Future work should focus on standardization of assessing the need for tracheostomy and the role of extubation attempts prior to tracheostomy placement.

Risk Factors for Tracheostomy after Traumatic Cervical Spinal Cord Injury: A 10-Year Study of 456 Patients

Objectives

To explore the difference between tracheostomy and non‐tracheostomy and identify the risk factors associated with the need for tracheostomy after traumatic cervical spinal cord injury (TCSCI).

Methods

The demographic and injury characteristics of 456 TCSCI patients, treated in the Xinqiao Hospital from 2010 to 2019, were retrospective analyzed. Patients were divided into the tracheostomy group (n = 63) and the non‐tracheostomy group (n = 393). Variables included were age, gender,smoking history, mechanism of injury, concomitant injury, American Spinal Injury Association (ASIA) Impairment Scale, the neurological level of injury, Cervical Spine Injury Severity Score (CSISS), surgery, and length of stay in ICU and hospital. SPSS 25.0 (SPSS, Chicago, IL) was used for statistical analysis and ROC curve drawing. Chi‐square analysis was applied to find out the difference of variables between the tracheostomy and non‐tracheostomy groups. Univariate logistic regression analysis (ULRA) and multiple logistic regression analysis (MLRA) were used to identify risk factors for tracheostomy. The area under the ROC curve (AUC) was used to evaluate the performance of these risk factors.

Results

Of 456 patients who met the inclusion criteria, 63 (13.8%) underwent tracheostomy. There were differences in age (χ² = 6.615, P = 0.032), mechanism of injury (χ² = 9.87, P = 0.036), concomitant injury (χ² = 6.131, P = 0.013),ASIA Impairment Scale (χ² = 123.08, P < 0.01), the neurological level of injury (χ² = 34.74, P < 0.01), and CSISS (χ² = 19.612, P < 0.01) between the tracheostomy and non‐tracheostomy groups. Smoking history, CSISS ≥ 7, AIS A and, NLI ≥ C5 were identified as potential risk factors for tracheostomy by ULRA. Smoking history (OR = 2.960, 95% CI: 1.524–5.750, P = 0.001), CSISS ≥ 7 (OR = 4.599, 95% CI: 2.328–9.085, P = 0.000), AIS A (OR = 14.213, 95% CI: 6.720–30.060, P = 0.000) and NLI ≥ C5 (OR = 8.312, 95% CI: 1.935–35.711, P = 0.004) as risk factors for tracheostomy were determined by MLRA. The AUC for the risk factors of tracheostomy after TCSCI was 0.858 (95% CI: 0.810–0.907).

Conclusions

Smoking history, CSISS ≥ 7, AIS A and, NLI ≥ C5 were identified as risk factors needing of tracheostomy in patients with TCSCI. These risk factors may be important to assist the clinical decision of tracheostomy.

Weaning from mechanical ventilation in neurocritical care

In the intensive care unit (ICU), weaning from mechanical ventilation follows a step-by-step process that has been well established in the general ICU population. However, little data is available in brain injury patients, who are often intubated to protect airways and prevent central hypoventilation. In this narrative review, we describe the general principles of weaning and how these principles can be adapted to brain injury patients. We focus on three major issues regarding weaning from mechanic ventilation in brain injury patients: (1) sedation protocol, (2) weaning and extubation protocol and criteria, (3) criteria, timing and technique for tracheostomy.

Effect of Early Tracheostomy on Mortality of Mechanically Ventilated Patients with Guillain-Barré Syndrome: A Nationwide Observational Study

Background

Patients with Guillain–Barré syndrome (GBS) who require mechanical ventilation (MV) are regarded as candidates for early tracheostomy because of the high risk of prolonged MV; however, the association between early tracheostomy and favorable outcomes in patients with GBS remains unclear. In this study, we evaluated the association between early tracheostomy and outcomes in mechanically ventilated patients with GBS.

Methods

This retrospective observational study included adult patients with GBS identified in the Japanese Diagnosis Procedure Combination national inpatient database from July 1, 2010, to March 31, 2018, who initiated MV within the first week of admission and who received MV for more than 1 week. Early tracheostomy was defined as tracheostomy performed within 7 days of MV. The primary outcome was in-hospital mortality, and the secondary outcomes were 28-day mortality, nosocomial pneumonia, length of hospital stay, length of intensive care unit (ICU) stay, duration of MV, duration of sedation, duration of analgesia, duration of delirium, and total hospitalization costs. Propensity scores for early tracheostomy were calculated using a logistic regression model on the following variables: age; sex; body mass index; Japan Coma Scale status at admission; Charlson comorbidity index score; comorbidity of chronic pulmonary disease; complication of pneumonia at admission; complication of hyponatremia at admission; neurological presentation at admission; ambulance use; referral from other hospitals; treatment year; days from hospital admission to MV initiation; ICU admission until the day of MV initiation; and treatments until the day of MV initiation. Stabilized inverse probability of treatment weighting analyses was performed to compare the outcomes between patients with and without early tracheostomy.

Results

Among 919 eligible patients, 654 patients (71%) underwent tracheostomy, with 136 patients (15%) receiving early tracheostomy. Overall, the median time from initiation of MV to tracheostomy was 12 days (interquartile range 8–15 days). After stabilized inverse probability of treatment weighting, early tracheostomy was not associated with lower in-hospital mortality (risk difference 0.4%; 95% confidence interval − 5.6 to 6.7%) compared with patients without early tracheostomy. There were no significant differences in 28-day mortality (risk difference − 1.3%; 95% confidence interval − 3.5 to 0.9%) and incidence of nosocomial pneumonia (risk difference − 2.6%; 95% confidence interval − 9.1 to 4.2%) between the two groups. None of the other secondary outcomes differed significantly between the groups.

Conclusions

Early tracheostomy was not significantly associated with decreased mortality or morbidity in patients with GBS requiring MV for more than 1 week.

Ultrasound use in the ICU for interventional pulmonology procedures

Critical care ultrasound has shifted the paradigm of thoracic imaging by enabling the treating physician to acquire and interpret images essential for clinical decision-making, at the bedside, in real-time. Once considered impossible, lung ultrasound based on interpretation of artifacts along with true images, has gained momentum during the last decade, as an integral part of rapid evaluation algorithms for acute respiratory failure, shock and cardiac arrest. Procedural ultrasound image guidance is a standard of care for both common bedside procedures, and advanced procedures within interventional pulmonologist’s (IP’s) scope of practice. From IP’s perspective, the lung, pleural, and chest wall ultrasound expertise is a prerequisite for mastery in pleural drainage techniques and transthoracic biopsies. Another ultrasound application of interest to the IP in the intensive care unit (ICU) setting is during percutaneous dilatational tracheostomy (PDT). As ICU demographics shift towards older and sicker patients, the indications for closed pleural drainage procedures, bedside transthoracic biopsies, and percutaneous dilatational tracheostomies have dramatically increased. Although ultrasound expertise is considered an essential IP operator skill there is no validated curriculum developed to address this component. Further, there is a need for developing an educational tool that matches up with the curriculum and could be integrated real-time with ultrasound-guided procedures.

Outcomes and Timing of Bedside Percutaneous Tracheostomy of COVID-19 Patients over a Year in the Intensive Care Unit

Background: The benefits and timing of percutaneous dilatational tracheostomy (PDT) in Intensive Care Unit (ICU) COVID-19 patients are still controversial. PDT is considered a high-risk procedure for the transmission of SARS-CoV-2 to healthcare workers (HCWs). The present study analyzed the optimal timing of PDT, the clinical outcomes of patients undergoing PDT, and the safety of HCWs performing PDT. Methods: Of the 133 COVID-19 patients who underwent PDT in our ICU from 1 April 2020 to 31 March 2021, 13 patients were excluded, and 120 patients were enrolled. A trained medical team was dedicated to the PDT procedure. Demographic, clinical history, and outcome data were collected. Patients who underwent PDT were stratified into two groups: an early group (PDT ≤ 12 days after orotracheal intubation (OTI) and a late group (>12 days after OTI). An HCW surveillance program was also performed. Results: The early group included 61 patients and the late group included 59 patients. The early group patients had a shorter ICU length of stay and fewer days of mechanical ventilation than the late group (p < 0.001). On day 7 after tracheostomy, early group patients required fewer intravenous anesthetic drugs and experienced an improvement of the ventilation parameters PaO₂/FiO₂ ratio, PEEP, and FiO₂ (p < 0.001). No difference in the case fatality ratio between the two groups was observed. No SARS-CoV-2 infections were reported in the HCWs performing the PDTs. Conclusions: PDT was safe and effective for COVID-19 patients since it improved respiratory support parameters, reduced ICU length of stay and duration of mechanical ventilation, and optimized the weaning process. The procedure was safe for all HCWs involved in the dedicated medical team. The development of standardized early PDT protocols should be implemented, and PDT could be considered a first-line approach in ICU COVID-19 patients requiring prolonged mechanical ventilation.

The role of routine FIBERoptic bronchoscopy monitoring during percutaneous dilatational TRACHeostomy (FIBERTRACH): a study protocol for a randomized, controlled clinical trial

Background

Tracheostomy is one of the most frequent techniques in intensive care units (ICU). Fiberoptic bronchoscopy (FB) is a safety measure when performing a percutaneous dilatational tracheostomy (PDT), but the controversy surrounding the routine use of FB as part of the procedure remains open. National surveys in some European countries showed that the use of FB is non-standardized. Retrospective studies have not shown a significant difference in complications between procedures performed with or without a bronchoscope. International guidelines have not been able to establish recommendations regarding the use of FB in PDT due to lack of evidence.

Design

This is a multicenter (three centers at the time of  publishing this paper) randomized controlled clinical trial to examine the safety of percutaneous tracheostomy using FB. We will include all consecutive adult patients admitted to the ICU in whom percutaneous tracheostomy for prolonged mechanical ventilation is indicated and with no exclusion criteria for using FB. Eligible patients will be randomly assigned to receive blind PDT or PDT under endoscopic guidance. All procedures will be performed by experienced intensivists in PDT and FB. A Data Safety and Monitoring Board (DSMB) will monitor the trial. The primary outcome is the incidence of perioperative complications.

Discussion

FB is a safe technique when performing PDT although its use is not universally accepted in all ICUs as a routine practice. Should PDT be monitored routinely with endoscopic guidance? This study will assess the role of FB monitoring during PDT.

Tracheostomy Practices for Mechanically Ventilated Patients in Malawi

Background

Tracheostomy is used for patients who require prolonged mechanical ventilation. Extensive research has described the provision and optimal timing of tracheostomy, but very little describes tracheostomy utilization in low- and middle-income countries, particularly in sub-Saharan Africa.

Methods

This prospective cohort study describes patients admitted to the intensive care unit (ICU) of a tertiary hospital in Malawi who received tracheostomy versus those who did not, with a primary outcome of hospital mortality. We performed subgroup analysis of patients with severe head injuries.

Results

The analysis included 451 patients admitted to the study ICU between September 2016 and July 2018. Overall hospital mortality was 40% for patients who received tracheostomy and 63% for patients who did not. Logistic regression modeling revealed an odds ratio (OR) of 0.34 (95% CI 0.18–0.64) for hospital mortality among patients who received tracheostomy versus those who did not (p < 0.001). Standardized mortality ratio weighting revealed an odds ratio of 0.81 (95% CI 0.65–0.99, p < 0.001) for hospital death among patients who received tracheostomy versus those who did not. In the subgroup excluding severe head injury, both ICU (50%) and hospital mortality (75%) were higher overall, but hospital mortality was not more common for patients with tracheostomy versus without (OR 1.28, 95% CI 0.94–1.74, p = 0.104).

Conclusions

Tracheostomy is not associated with hospital mortality in a Malawi ICU cohort, but these results are affected by the presence of head injury. Research may focus on home tracheostomy care given the lack of hospital discharge options for patients in austere settings.

Standardized Endoscopic Swallowing Evaluation for Tracheostomy Decannulation in Critically Ill Neurologic Patients - a prospective evaluation

Background

Removal of a tracheostomy tube in critically ill neurologic patients is a critical issue during intensive care treatment, particularly due to severe dysphagia and insufficient airway protection. The “Standardized Endoscopic Evaluation for Tracheostomy Decannulation in Critically Ill Neurologic Patients” (SESETD) is an objective measure of readiness for decannulation. This protocol includes the stepwise evaluation of secretion management, spontaneous swallowing, and laryngeal sensitivity during fiberoptic endoscopic evaluation of swallowing (FEES). Here, we first evaluated safety and secondly effectiveness of the protocol and sought to identify predictors of decannulation success and decannulation failure.

Methods

A prospective observational study was conducted in the neurological intensive care unit at Münster University Hospital, Germany between January 2013 and December 2017. Three hundred and seventy-seven tracheostomized patients with an acute neurologic disease completely weaned from mechanical ventilation were included, all of whom were examined by FEES within 72 h from end of mechanical ventilation. Using regression analysis, predictors of successful decannulation, as well as decannulation failure were investigated.

Results

Two hundred and twenty-seven patients (60.2%) could be decannulated during their stay according to the protocol, 59 of whom within 24 h from the initial FEES after completed weaning. 3.5% of patients had to be recannulated due to severe dysphagia or related complications. Prolonged mechanical ventilation showed to be a significant predictor of decannulation failure. Lower age was identified to be a significant predictor of early decannulation after end of weaning. Transforming the binary SESETD into a 4-point scale helped predicting decannulation success in patients not immediately ready for decannulation after the end of respiratory weaning (optimal cutoff ≥1; sensitivity: 64%, specifity: 66%).

Conclusions

Construction of a detachable artificial trachea model for three age groups for use in an endotracheal suctioning training environment simulator

Tracheal suctioning is an important procedure to maintain airway patency by removing secretions. Today, suctioning operators include not only medical staff, but also family caregivers. The use of a simulation system has been noted to be the most effective way to learn the tracheal suctioning technique for operators. While the size of the trachea varies across different age groups, the artificial trachea model in the simulation system has only one fixed model. Thus, this study aimed to construct multiple removable trachea models according to different age groups. We enrolled 20 patients who had previously received proton beam therapy in our institution and acquired the treatment planning computed tomography (CT) image data. To construct the artificial trachea model for three age groups (children, adolescents and young adults, and adults), we analyzed the three-dimensional coordinates of the entire trachea, tracheal carina, and the end of the main bronchus. We also analyzed the diameter of the trachea and main bronchus. Finally, we evaluated the accuracy of the model by analyzing the difference between the constructed model and actual measurements. The trachea model was 8 cm long for children and 12 cm for adolescents and young adults, and for adults. The angle between the trachea and bed was about 20 degrees, regardless of age. The mean model accuracy was less than 0.4 cm. We constructed detachable artificial trachea models for three age groups for implementation in the endotracheal suctioning training environment simulator (ESTE-SIM) based on the treatment planning CT image. Our constructed artificial trachea models will be able to provide a simulation environment for various age groups in the ESTE-SIM.

Percutaneous dilatational tracheostomy for saturating influx of COVID-19 patients: Experience of military ENT physicians deployed in Mulhouse, France

OBJECTIVES

The main objective was to demonstrate the feasibility of percutaneous tracheostomy performed under difficult conditions by military ENT physicians during their deployment in the military intensive care field hospital of the French Military Medical Service in Mulhouse to confront the exceptional COVID-19 pandemic. The secondary objective was to assess reliability and safety for patient and caregivers, with a risk of iatrogenic viral contamination.

MATERIAL AND METHODS

A single-center retrospective study was conducted between March 25 and April 25, 2020, in 47 COVID-19 patients requiring prolonged mechanical ventilation. The inclusion criterion was having undergone percutaneous tracheostomy.

RESULTS

Eighteen consecutively included patients had successfully undergone percutaneous tracheostomy despite unfavorable anatomical conditions (short neck: 83.3%, overweight or obese: 88.9%). Median time to completion was 11 days after intubation, with an average duration of 7minutes. The procedure was technically compliant in 83.3% of cases, and considered easy (on self-assessment) in 72.2%, with 2 minor per-procedural complications. No crossover to surgery was required. There was only 1 major post-procedural complication (late hemorrhage).

CONCLUSION

This study showed the feasibility of percutaneous tracheostomy by an ENT physician under COVID-19 biohazard conditions. The technique was fast, easy and safe and met safety requirements for patient and staff.

Diagnosis and treatment of emergency surgeries in otorhinolaryngology, head and neck surgery during the covid-19 outbreak: A single center experience

The 2019 Novel Coronavirus (2019-nCoV, SARS-CoV-2) infection has already been assigned as a Class B infectious disease requiring Class A management strategy according to “the Law on the Prevention and Control of Infectious Diseases of the People's Republic of China” and become a global pandemic. The incidence of emergencies in otorhinolaryngology, head and neck surgery such as foreign bodies in the esophagus and the respiratory tract, epistaxis, laryngeal obstruction with dyspnea, and head and neck trauma are relatively high. Emergency surgeries are required as some of these diseases progress rapidly and probably be life-threatening. In this article, we drafted the recommendations for diagnosis and treatment of emergency surgeries in otorhinolaryngology, head and neck surgery in the epidemic area of novel coronavirus pneumonia based on “Novel Coronavirus Pneumonia Diagnosis and Treatment Plan (Provisional; 7th Edition Revisions)”and WHO guidelines, combined with the experience of emergency surgeries in the Department of Otorhinolaryngology, Wuhan Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, which is at the center outbreak area of the SARS-CoV-2 pneumonia (COVID-19) in China, to improve the success rate of treatment for otorhinolaryngology, head and neck surgery emergency surgeries and to reduce the SARS-CoV-2 infection rate in the perioperative period.

Inter-rater and test-retest reliability of the "standardized endoscopic swallowing evaluation for tracheostomy decannulation in critically ill neurologic patients"

Background

Removal of a tracheostomy tube in critically ill neurologic patients is a difficult issue, particularly due to the high incidence of oropharyngeal dysphagia. For an objective evaluation of decannulation readiness the "Standardized Endoscopic Swallowing Evaluation for Tracheostomy Decannulation in Critically Ill Neurologic Patients" (SESETD) - a stepwise evaluation of 'secretion management', 'spontaneous swallows' and 'laryngeal sensibility/cough' - has been introduced. With the recent study detailed data on inter-rater and test-retest reliability are presented.

Methods

To obtain inter-rater reliability levels both in a group of raters with at least 5 years of experience ('experts') and in a group of raters with no or only minor experience using the SESETD ('non-experts'), for each single item of the protocol and the sum score α-, respectively κ-levels were determined. The 'experts' assessed the same videos after a four-week interval to determine test-retest reliability. Ten videos from tracheostomized neurological patients completely weaned from mechanical ventilation were assessed independently by six 'experts'. 27 'non-experts' applied the SESETD on 5 videos from the same patient population after introduction to the protocol in a one-hour workshop.

Results

For the items 'secretion management' and 'spontaneous swallows' α-levels were identified at > 0.800 both in the group of 'experts' and 'non-experts'. With regard to the item 'laryngeal sensibility/cough' in both groups, the α-level was ≥0.667. With κ-levels of 1.0 for 'secretion management', 0.93 for 'spontaneous swallows' and 0.76 for 'laryngeal sensibility/cough' test-retest reliability showed at least substantial agreement for each item. Intraclass correlation coefficient for the sum score was excellent in both groups (α ≥ 0.90).

Conclusions

The SESETD demonstrates good to excellent agreement for each single item included as well as the sum score in experienced and unexperienced raters supporting its usefulness for implementation in daily clinical routine and as an outcome measure for clinical trials.

Tracheotomy When and Where?

The time for elective tracheotomies has been discussed for years in what has become very comprehensive literature by now. In this chapter, studies with high levels of evidence are taken into account and recommendations are given for the timing of tracheotomies in long-term ventilated patients, with the individual decision being at the center of consideration.

Tracheotomies can be performed both in the operating room and in an intensive care unit. The criteria for such choice are presented under interdisciplinary medical and organizational aspects.

Long-Term Survival of Patients with Tracheostomy Having Different Diseases Followed up in the Respiratory Intensive Care Unit Outpatient Clinic: Which Patients are Lucky?

OBJECTIVES

Tracheostomy is a method of separating a patient from the mechanical ventilator in the intensive care unit (ICU). The long-term survivors among patients followed up with tracheostomy and ventilator in the respiratory ICU (RICU) outpatient clinic due to different diseases were investigated.

MATERIALS AND METHODS

This was a retrospectively designed cohort study between January 2004 and July 2018. Patients with chronic respiratory failure followed up with tracheostomy and/or ventilator at the RICU outpatient clinic were included in the study. Age, gender, indications and date of tracheostomy, use of domestic mechanical ventilation, and mortality were recorded. The groups were compared according to age, gender, and tracheostomy indication diseases, and the 1-3-year long-term mortality rates were analyzed by the Kaplan-Meier survival analysis, and the Cox regression test was performed.

RESULTS

A total of 134 (64% male) patients with a median age of 66 (54-73) years were included in the study. The indications for tracheostomy were heart failure (HF) and cerebrovascular diseases (38.1%), chronic obstructive pulmonary disease (COPD) (23.1%), neuromuscular diseases (22.4%), obesity hypoventilation (9.7%), and kyphoscoliosis (6.7%). Mortality was higher in patients >75 years old in the 3-year follow-up (p=0.022). The 3-year mortality hazard ratio (HR) factors and 95% confidence interval (CI) were as follows: age >75 years HR=1.71 (95% CI, 1.03-2.82; p<0.036) and HF and cerebrovascular disease diseases sequela HR=1.84 (95% CI, 1.03-3.29; p<0.041) significantly increased the 3-year mortality, and having COPD decreased mortality in 46% (p<0.041).

CONCLUSION

Patients with neuromuscular disorders, kyphoscoliosis, and COPD who have undergone tracheostomy were the luckiest group according to the 3-year survival rates, whereas patients with HF and cerebrovascular diseases were the unluckiest ones. The most important decision triangle is the patient's acceptance (A), family support (B), and tracheostomy indication (C), and this may vary from country to country depending on the beliefs of subjects.
