We assessed the effects of tracheostomy timing (early vs. late) on outcomes among adult patients receiving mechanical ventilation. PubMed, Embase, Web of Science and Cochrane Library were searched to identify relevant RCTs of tracheotomy timing on patients receiving mechanical ventilation. Two reviewers independently screened the literature, extracted data. Outcomes in patients with early tracheostomy and late tracheostomy groups were compared and analyzed. Meta-analysis was performed using Stata14.0 and RevMan 5.4 software. This study is registered with PROSPERO (CRD42022360319). Twenty-one RCTs were included in this Meta-analysis. The Meta-analysis indicated that early tracheotomy could significantly shorten the duration of mechanical ventilation (MD: -2.77; 95% CI -5.10~ -0.44; P = 0.02) and the length of ICU stay (MD: -6.36; 95% CI -9.84~ -2.88; P = 0.0003), but it did not significantly alter the all-cause mortality (RR 0.86; 95% CI 0.73~1.00; P = 0.06), the incidence of pneumonia (RR 0.86; 95% CI 0.74~1.01; P = 0.06), and length of hospital stay (MD: -3.24; 95% CI -7.99~ 1.52; P = 0.18). In patients requiring mechanical ventilation, the tracheostomy performed at an earlier stage may shorten the duration of mechanical ventilation and the length of ICU stay but cannot significantly decrease the all-cause mortality and incidence of pneumonia.

Background Percutaneous dilatational tracheostomy (PDT) is a common procedure for mechanically ventilated patients in the intensive care unit (ICU). This study compared the real-time ultrasound-guided PDT using a laryngeal mask airway (LMA) with the standard bronchoscopy-guided PDT technique in ICU patients requiring elective tracheostomy. Methods This randomized controlled study was conducted at Ain Shams University Hospital’s Critical Care Department from December 4th, 2021, to December 3rd, 2022. The study population included 60 critically ill patients admitted to the ICU. Thirty patients were randomly assigned to the real-time ultrasound-guided LMA-assisted group, and 30 patients were randomly assigned to the bronchoscopy-guided technique. The primary study outcome was the procedure time, and the secondary outcomes included procedure-related complications rate and cost-effectiveness. Results The real-time ultrasound-guided LMA-assisted group had significantly shorter procedure time (median 17 [IQR: 15–20] min vs. 35 [IQR: 28–39] min, p  < 0.001) and lower equipment damage (0% vs. 20%, p  = 0.024) during the procedure compared to the bronchoscopy-guided group. Additionally, the cost of tracheostomy was significantly lower in the real-time ultrasound-guided LMA-assisted group (median: 300 vs. 800 USD, p  < 0.001). The real-time ultrasound-guided LMA group had a lower major complications rate than the bronchoscopy-guided group (36.7%) vs. 3.3%, p  = 0.002). Conclusions The study demonstrated that real-time ultrasound-guided LMA-assisted PDT had shorter procedure time, reduced equipment damage, lower costs, and was associated with lower complications when compared to the bronchoscopy-guided technique. These findings suggest that ultrasound guidance can enhance the efficiency and cost-effectiveness of PDT procedures.

Surgical tracheostomy (ST) and Percutaneous dilatational tracheostomy (PDT) are classified as high-risk aerosol-generating procedures and might lead to healthcare workers (HCW) infection. Albeit the COVID-19 strain slightly released since the vaccination era, preventing HCW from infection remains a major economical and medical concern. To date, there is no study monitoring particle emissions during ST and PDT in a clinical setting. The aim of this study was to monitor particle emissions during ST and PDT in a swine model. A randomized animal study on swine model with induced acute respiratory distress syndrome (ARDS) was conducted. A dedicated room with controlled airflow was used to standardize the measurements obtained using an airborne optical particle counter. 6 ST and 6 PDT were performed in 12 pigs. Airborne particles (diameter of 0.5 to 3 μm) were continuously measured; video and audio data were recorded. The emission of particles was considered as significant if the number of particles increased beyond the normal variations of baseline particle contamination determinations in the room. These significant emissions were interpreted in the light of video and audio recordings. Duration of procedures, number of expiratory pauses, technical errors and adverse events were also analyzed. 10 procedures (5 ST and 5 PDT) were fully analyzable. There was no systematic aerosolization during procedures. However, in 1/5 ST and 4/5 PDT, minor leaks and some adverse events (cuff perforation in 1 ST and 1 PDT) occurred. Human factors were responsible for 1 aerosolization during 1 PDT procedure. ST duration was significantly shorter than PDT (8.6 ± 1.3 vs 15.6 ± 1.9 minutes) and required less expiratory pauses (1 vs 6.8 ± 1.2). COVID-19 adaptations allow preventing for major aerosol leaks for both ST and PDT, contributing to preserving healthcare workers during COVID-19 outbreak, but failed to achieve a perfectly airtight procedure. However, with COVID-19 adaptations, PDT required more expiratory pauses and more time than ST. Human factors and adverse events may lead to aerosolization and might be more frequent in PDT.

Background: Performing tracheostomy improves patient comfort and success rate of weaning from prolonged invasive mechanical ventilation. Data suggest that patients have more benefit of percutaneous technique than the surgical procedure, however, there is no consensus on the percutaneous method of choice regarding severe complications such as late tracheal stenosis. Aim of this study was comparing incidences of cartilage injury caused by different percutaneous dilatation techniques (PDT), including Single Dilator, Griggs’ and modified (bidirectional) Griggs’ method. Materials and methods: Randomized observational study was conducted on 150 cadavers underwent post-mortem percutaneous tracheostomy. Data of cadavers including age, gender and time elapsed from death until the intervention (more or less than 72 h) were collected and recorded. Primary and secondary outcomes were: rate of cartilage injury and cannula malposition respectively. Results: Statistical analysis revealed that method of intervention was significantly associated with occurrence of cartilage injury, as comparing either standard Griggs’ with Single Dilator ( p = 0.002; OR: 4.903; 95% CI: 1.834–13.105) or modified Griggs’ with Single Dilator ( p < 0.001; OR: 6.559; 95% CI: 2.472–17.404), however, no statistical difference was observed between standard and modified Griggs’ techniques ( p = 0.583; OR: 0.748; 95% CI: 0.347–1.610). We found no statistical difference in the occurrence of cartilage injury between the early- and late post-mortem group ( p = 0.630). Neither gender ( p = 0.913), nor age ( p = 0.529) influenced the rate of cartilage fracture. There was no statistical difference between the applied PDT techniques regarding the cannula misplacement/malposition. Conclusion: In this cadaver study both standard and modified Griggs’ forceps dilatational methods were safer than Single dilator in respect of cartilage injury.

Purpose To assess the effectiveness of a new suturing technique called Dragonfly for the closure of temporary tracheotomies. This technique involves placing two sutures during the tracheotomy procedure and leaving them loose and unknotted until the day of skin closure. Methods Retrospective case control study. Monocentric study at a department of Otolaryngology and head and neck surgery at a tertiary centre in Italy. A total of 50 patients who underwent temporary tracheotomy between January 2017 and December 2021. Patients were divided into two groups based on the trachea closure method: traditional closure with sutures placed during the skin closure procedure (Group A) and the Dragonfly technique (Group B). The incidence of tracheal stenosis by Computed Tomography (CT), granulation tissue formation, bleeding, procedure duration, patient discomfort were evaluated. Results The incidence of tracheal complications and tracheal stenosis was reduced in Group B (6%) compared to Group A (24%). Procedure times (3 min vs. 6 min) durations was significantly shorter. No patients had symptoms of tracheal stenosis at the end of the procedures. Conclusion The Dragonfly suturing technique is effective and safe for tracheotomy closure, reducing the incidence of tracheal stenosis and shortening hospitalization duration compared to the traditional method.

Background Tracheostomy in mechanically ventilated patients with severe stroke can be performed surgically or dilationally. Prospective data comparing both methods in patients with stroke are scarce. The randomized Stroke-Related Early Tracheostomy vs Prolonged Orotracheal Intubation in Neurocritical Care Trial2 (SETPOINT2) assigned 382 mechanically ventilated patients with stroke to early tracheostomy versus extubation or standard tracheostomy. Surgical tracheostomy (ST) was performed in 41 of 307 SETPOINT2 patients, and the majority received dilational tracheostomy (DT). We aimed to compare ST and DT in these patients with patients. Methods All SETPOINT2 patients with ST were compared with a control group of patients with stroke undergoing DT (1:2), selected by propensity score matching that included the factors stroke type, SETPOINT2 randomization group, Stroke Early Tracheostomy score, patient age, and premorbid functional status. Successful decannulation was the primary outcome, and secondary outcome parameters included functional outcome at 6 months and adverse events attributable to tracheostomy. Potential predictors of decannulation were evaluated by regression analysis. Results Baseline characteristics were comparable in the two groups of patients with stroke undergoing ST ( n  = 41) and matched patients with stroke undergoing DT ( n  = 82). Tracheostomy was performed significantly later in the ST group than in the DT group (median 9 [interquartile range {IQR} 5–12] vs. 9 [IQR 4–11] days after intubation, p  = 0.025). Patients with ST were mechanically ventilated longer (median 19 [IQR 17–24] vs.14 [IQR 11–19] days, p  = 0.008) and stayed in the intensive care unit longer (median 23 [IQR 16–27] vs. 17 [IQR 13–24] days, p  = 0.047), compared with patients with DT. The intrahospital infection rate was significantly higher in the ST group compared to the DT group (14.6% vs. 1.2%, p  = 0.002). At 6 months, decannulation rates (56% vs. 61%), functional outcomes, and mortality were not different. However, decannulation was performed later in the ST group compared to the DT group (median 81 [IQR 66–149] vs. 58 [IQR 32–77] days, p  = 0.004). Higher baseline Stroke Early Tracheostomy score negatively predicted decannulation. Conclusions In ventilated patients with severe stroke in need of tracheostomy, surgical and dilational methods are associated with comparable decannulation rate and functional outcome at 6 months. However, ST was associated with longer time to decannulation and higher rates of early infections, supporting the dilational approach to tracheostomy in ventilated patients with stroke.

Cricothyrotomy is a rare, time sensitive procedure that is more challenging to perform when anatomical landmarks are not easily palpated before the initial incision. There is a paucity of literature describing the optimal technique for cricothyrotomy in patients with impalpable airway structures, such as in morbid obesity. In this study, we used a live sheep model of morbid obesity to compare the effectiveness of two common cricothyrotomy techniques. We randomly assigned emergency medicine residents to perform one of two cricothyrotomy techniques on a live anesthetized sheep. To simulate the anterior soft tissue neck thickness of an adult with morbid obesity we injected 120 mL of a mixture of autologous blood and saline into the anterior neck of the sheep. The traditional technique (as described in the New England Journal Video titled “Cricothyroidotomy”) used a Shiley tracheostomy tube and no bougie, and the bougie-guided technique used a bougie and a standard endotracheal tube. The primary outcome was the total procedure time; the secondary outcome was first attempt success. 23 residents were included, 11 assigned to the bougie-guided technique and 12 to the traditional technique. After injection of blood and saline, the median depth from skin to cricothyroid membrane was 3.0 cm (IQR 2.5–3.4 cm). The median time for the bougie technique was 118 s (IQR 77–200 s) compared to 183 s (IQR 134–270 s) for the traditional technique (median difference 62 s, 95% CI 10–144 s). Success on the first attempt occurred in 7/11 (64%) in the bougie group and 6/12 (50%) in the traditional technique group. In this study, which simulated morbid obesity on a living animal model complete with active hemorrhage and time pressure caused by extubation before the procedure, the bougie-guided technique was faster than the traditional technique using a tracheostomy tube without a bougie.

Tracheotomy is an emergency surgical procedure that first appeared and was developed in ancient times. Surgical techniques for tracheotomy have been perfected in modern times, and in adults it is one of the most common surgical procedures performed in emergency departments and intensive care units worldwide. In children, however, tracheotomies present far greater challenges to the medical teams involved. A number of related issues - indications and contraindications, time to perform, and protocols for decannulation, among others - still need to be clarified. In recent years, the development of medical science, the introduction of vaccination programs, the use of many improved medical materials and technologies, and the achievements in neonatal and pediatric intensive care have changed the focus of pediatric tracheostomy from its emergency performance to solve acute asphyxiation problem to its implementation in children, who represent a complex group of patients with permanent dependence on tracheostomy and related medical technologies for long-term survival. There is a growing number of children who have had complex therapy and for whom tracheostomy care and mechanical ventilation are part of their care, including in the home environment. This in turn raises new questions: Who will care for the child in the early post-operative period and after hospitalization? Who will train people to care for the tracheostomized child at home? What precautions should be taken with these children during their daily activities, including eating, bathing, and playing inside and outside the home?

1 Introduction 1.1 Background Cricothyrotomy is the final common pathway of providing a secure airway [1-5]. [...]for prehospital personnel this is the main method for obtaining a secure airway under Tactical Combat Casualty Care (TCCC) guidelines [6]. Using this device, Murphy et al. found faster insertion times and caused less trauma to the posterior tracheal wall compared to the standard open surgical technique [9].1.2 Goal of the investigation To compare cricothyrotomy insertion times a standard open surgical technique versus the trochar-based QuickTrach2™ using a sus scrofa model.2 Methods 2.1 Study design and setting We conducted a randomized crossover trial of emergency medicine resident physicians and emergency medicine physician assistant fellow using a sus scrofa model. Successful cannulation was assessed by direct visualization of the euthanized animal through examination and dissection.2.5 Analysis We aggregated the data using Microsoft Excel (version 10, Microsoft, Redmond, Washington). and exported for analysis into JMP Statistical Discovery from SAS (version 13, Cary, NC).3 Results There were 13 subjects that completed both arms.

Background Apart from conventional reusable bronchoscopes, single-use bronchoscopes (SUB) were recently introduced. Data suggest that SUB might prevent from the risk of cross contamination (i.e. multiresistant pathogens, SARS CoV-2) and save costs. We aimed to investigate visualization, ventilation, handling characteristics, changes in patients’ gas exchange, and costs associated with both types of bronchoscopes during percutaneous dilatational tracheostomy (PDT). Methods In this prospective, randomized, noninferiority study, 46 patients undergoing PDT were randomized 1:1 to PDT with SUB (Ambu aScope) or reusable bronchoscopes (CONV, Olympus BF-P60). Visualization of tracheal structures rated on 4-point Likert scales was the primary end-point. Furthermore, quality of ventilation, device handling characteristics, changes in the patients’ gas exchange, pH values, and costs were assessed. Results Noninferiority for visualization (the primary endpoint) was demonstrated for the SUB group. Mean visualization scores (lower values better) were 4.1 (95% confidence intervals: 3.9;4.3) for SUB vs. 4.1 (4.0;4.2) for CONV. Noninferiority of ventilation (estimated by minute volume and SpO 2 ) during the procedure could be shown as well. Mean score was 2.6 (2.0;3.1) for SUB vs. 2.4 (2.1;2.7) for CONV (lower values better). No significant differences regarding handling (SUB: 1.2 (1.0;1.4), CONV: 1.3 (1.1;1.6)), blood gas analyses and respiratory variables were found. Cost analysis in our institution revealed 93 € per conventional bronchoscopy versus 232.50 € with SUB, not considering an estimate for possible infection due to cross-contamination with the reusable device. Conclusion In our study, visualization and overall performance of the SUB during PDT were noninferior to reusable bronchoscopes. Therefore, PDT with SUB is feasible and should be considered if favored by individual institution’s cost analysis. Trial registration. ClinicalTrials.gov, NCT03952247 .
