UNASSIGNED: Tracheostomy decannulation in children with craniofacial deformities poses challenges due to airway obstruction and the developing brain. This study aimed to compare decannulation outcomes based on age at tracheostomy and duration of cannulation so as to identify the best time for decannulation for children with long-term tracheostomy.
UNASSIGNED: This retrospective study included 12 children at a single centre who underwent decannulation after prolonged tracheostomy for craniofacial deformities. Data on demographics, clinical features, decannulation process and outcomes were collected. Children were divided into two groups: ≤6 years (n = 7) and >6 years (n = 5) at tracheostomy insertion.
UNASSIGNED: All children underwent successful decannulation without immediate complications. One case of mild tracheomalacia and one of subglottic stenosis were treated pre-decannulation. Children ≤6 years demonstrated better post-operative adaptation in swallowing and speaking compared to the >6 years group. Notably, early and prolonged tracheostomy in the ≤6 years group was associated with easier adaptation post-decannulation. Social interaction was another challenge, particularly for the >6 years group.
UNASSIGNED: The timing and duration of tracheostomy significantly impacts post-decannulation adaptation, likely due to factors such as neuroplasticity, muscle memory and psychological adjustment. This emphasises the need for comprehensive care, especially for older children. Early tracheostomy in children may allow them to adapt speech and swallowing skills, easing post-decannulation regain of skills. Conversely, older children with fully developed skills may struggle to relearn them after tracheostomy and decannulation. Age at tracheostomy and duration of cannulation influences decannulation outcomes in children with craniofacial deformities. Further research is crucial to develop targeted interventions for better post-operative care, particularly for older children.

BACKGROUND: Clinical blood resources are scarce and autologous blood transfusion for extracorporeal membrane oxygenation (ECMO) withdrawal is less studied.
OBJECTIVE: To assess the use of staged autotransfusion during ECMO decannulation.
METHODS: The study included ECMO withdrawal patients. Patients in the autologous transfusion group underwent staged transfusion during ECMO withdrawal, while those in the control group received 2.0 units of allogeneic packed red blood cells (RBCs) to increase hemoglobin (Hb). Parameters such as Hb, hematocrit (Hct), adverse events, decannulation success rate, volume of allogeneic RBC transfusions, and transfusion costs were compared.
RESULTS: A total of 82 Chinese patients were enrolled, with a mean age of 46 years, 27 were female, and the top three primary diagnoses were cardiac arrest, acute myocarditis, and severe pneumonia. There were 41 individuals in the autologous blood transfusion group and 41 in the control group. No significant differences were observed in Hb, Hct, adverse events, and the success rate for decannulation between the two groups (all P > 0.05). Compared with the control group, the volume of allogeneic RBC transfusions [0 (0∼1.50) U vs. 3.5 (1.88∼40) U, P < 0.001] and the total cost [130 (130∼390) Chinese Yuan (CNY) vs. 910 (487.50, 1040) CNY, P = 0.002] were lower in the autologous transfusion group.
CONCLUSIONS: In comparison with allogeneic RBC transfusion, staged autotransfusion during ECMO decannulation not only effectively maintained Hb levels but also reduced the requirement for allogeneic RBC transfusions. In addition, this approach decreased the associated costs and did not increase the risk of clinical adverse events.

BACKGROUND: Decannulation for people in a persistent vegetative state (PVS) is challenging and relevant predictors of successful decannulation have yet to be identified.
OBJECTIVE: This study aimed to explore the predictors of tracheostomy decannulation outcomes in individuals in PVS and to develop a nomogram.
METHODS: In 2022, 872 people with tracheostomy in PVS were retrospectively enrolled and their data was randomly divided into a training set and a validation set in a 7:3 ratio. Univariate and multivariate regression analyses were performed on the training set to explore the influencing factors for decannulation and nomogram development. Internal validation was performed using 5-fold cross-validation. External validation was performed using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA) on both the training and validation sets.
RESULTS: Data from 610 to 262 individuals were used for the training and validation sets, respectively. The multivariate regression analysis found that duration of tracheostomy tube placement≥30 days (Odds Ratio [OR] 0.216, 95 % CI 0.151-0.310), pulmonary infection (OR 0.528, 95 %CI 0.366-0.761), hypoproteinemia (OR 0.669, 95 % CI 0.463-0.967), no passive standing training (OR 0.372, 95 % CI 0.253-0.547), abnormal swallowing reflex (OR 0.276, 95 % CI 0.116-0.656), mechanical ventilation (OR 0.658, 95 % CI 0.461-0.940), intensive care unit (ICU) duration>4 weeks (OR 0.517, 95 % CI 0.332-0.805), duration of endotracheal tube (OR 0.855, 95 % CI 0.803-0.907), older age (OR 0.981, 95 % CI 0.966-0.996) were risk factors for decannulation failure. Conversely, peroral feeding (OR 1.684, 95 % CI 1.178-2.406), passive standing training≥60 min (OR 1.687, 95 % CI 1.072-2.656), private caregiver (OR 1.944, 95 % CI 1.350-2.799) and ICU duration<2 weeks (OR 1.758, 95 % CI 1.173-2.634) were protective factors conducive to successful decannulation. The 5-fold cross-validation revealed a mean area under the curve of 0.744. The ROC curve C-indexes for the training and validation sets were 0.784 and 0.768, respectively, and the model exhibited good stability and accuracy. The DCA revealed a net benefit when the risk threshold was between 0 and 0.4.
CONCLUSIONS: The nomogram can help adjust the treatment and reduce decannulation failure.
BACKGROUND: Clinical registration is not mandatory for retrospective studies.

Concurrently to the recent development of percutaneous tracheostomy techniques in the intensive care unit (ICU), the amount of tracheostomized brain-injured patients has increased. Despites its advantages, tracheostomy may represent an obstacle to their orientation towards conventional hospitalization or rehabilitation services. To date, there is no recommendation for tracheostomy weaning outside of the ICU. We created a pluridisciplinary tracheostomy weaning protocol relying on standardized criteria but adapted to each patient\'s characteristics and that does not require instrumental assessment. It was tested in a prospective, single-centre, non-randomized cohort study. Inclusion criteria were age > 18 years, hospitalized for an acquired brain injury (ABI), tracheostomized during an ICU stay, and weaned from mechanical ventilation. The exclusion criterion was severe malnutrition. Decannulation failure was defined as recannulation within 96 h after decannulation. Thirty tracheostomized ABI patients from our neurosurgery department were successively and exhaustively included after ICU discharge. Twenty-six patients were decannulated (decannulation rate, 90%). None of them were recannulated (success rate, 100%). Two patients never reached the decannulation stage. Two patients died during the procedure. Mean tracheostomy weaning duration (inclusion to decannulation) was 7.6 (standard deviation [SD]: 4.6) days and mean total tracheostomy time (insertion to decannulation) was 42.5 (SD: 24.8) days. Our results demonstrate that our protocol might be able to determine without instrumental assessment which patient can be successfully decannulated. Therefore, it may be used safely outside ICU or a specialized unit. Moreover, our tracheostomy weaning duration is very short as compared to the current literature.

UNASSIGNED: Rational prediction of the probability of decannulation in tracheotomy patients is of great importance to clinicians and patients\' families. This study aimed to develop a prediction model for decannulation in tracheotomized patients with neurological injury using routine clinical data and blood tests.
UNASSIGNED: We developed a prediction model based on 186 tracheotomized patients, and data were collected from January 2018 to March 2021. The least absolute shrinkage and selection operator (LASSO) regression model was used to optimize feature selection for the decannulation risk model. The performance of the prediction model was evaluated in terms of discrimination, calibration, and clinical utility using measures such as C-index, calibration plot, and decision curve analysis (DCA). Internal validation was performed through bootstrapping validation.
UNASSIGNED: A total of 66.13% (123/186) of patients were decannulated. Predictors included in the prediction nomogram were age, gender, subtype of neurological injury, Glasgow Coma Scale (GCS) score, swallowing function, duration of tracheotomy, procalcitonin (PCT) level, white blood cell (WBC) count, and serum albumin (ALB) level. The predictive model showed good discrimination, with a C-index of 0.755 (95% confidence interval: 0.68-0.83). Internal validation also confirmed a satisfactory C-index of 0.690. The DCA indicated that the nomogram added substantial value in predicting decannulation risk for patients with threshold probabilities falling between >21% and <98% compared to the existing scheme.
UNASSIGNED: This predictive model serves as a valuable instrument for clinicians to quantitatively assess the probability of decannulation in patients with neurological injury, aiding in informed decision-making and patient management.

A prospective observational study was done with the aim to analyze the difficulties during decannulation of tracheostomized head injury patients and to devise a sound protocol for decannulation. It was done over 2 years in a tertiary care Army Hospital with 40 tracheostomized head injury cases in the age group of 10-70 years. Once the indication of tracheostomy was over, their Glasgow Coma Scale score, airway adequacy, phonation, swallowing, cough reflex, and lung pathology were assessed. Fit patients were decannulated if they tolerated tube capping for 3 days. Data was statistically analyzed. Road traffic accident was the cause of head injury in 90% cases. 45% patients had traumatic brain injury. All the cases required ventilatory support. 80% patients required neurosurgery. Tracheostomy was done between 5th to 10th day. Decannulation could be achieved in 75% patients. Factors like neurological status, duration of ventilatory need, number of days on T piece, cough reflex, suction requirement, phonation, consistency of tracheal secretion, lung condition, and three days? capping of tracheostomy tube were significantly associated with outcome of decannulation trial (p <0.05). Factors like mode of injury, neurosurgical intervention, absence of phonation, and downsizing of tube did not affect the outcome significantly (p >0.05). The factors like strong cough reflex, thin minimal tracheal secretion, aspiration free swallowing, better GCS score, early weaning from ventilator and younger age favour early successful decannulation. Gradual downsizing of tube or presence of phonation are not essential prerequisites for decannulation.

BACKGROUND: The venoarterial extracorporeal membrane oxygenation (VA-ECMO) cannula can be surgically removed, but postoperative complications and surgical staffing issues can be problematic. We previously reported a method of percutaneously removing the arterial cannula of VA-ECMO by combining intravascular balloon dilation and the Perclose ProGlide (PP) closure device. In this study, we investigated the efficacy and safety of this percutaneous decannulation of the VA-ECMO.
METHODS: This multicenter, retrospective study involved consecutive patients who underwent percutaneous VA-ECMO decannulation at 2 cardiovascular centers from September 2019 to December 2021. We analyzed 37 patients in whom the VA-ECMO cannula was removed by the percutaneous procedure with balloon dilation and the PP. The primary end point was procedural success of hemostasis. The secondary end points were the procedural time, procedure-related complications, and rate of surgical conversion.
RESULTS: The patients\' mean age was 65.4 years. The approach site of the endovascular therapy (EVT) procedures were the transradial approach (56.8%), transfemoral approach (27.8%), and transbrachial approach (18.9%). The mean balloon diameter was 7.3 ± 0.68 mm, and the mean balloon inflation time was 14.8 ± 7.3 min. The mean procedure time was 58.5 ± 27.0 min. The procedure success rate was 94.6%, procedure-related complication rate was 10.8%, procedure-related death and postprocedural infection rate was 0.0%, surgical conversion rate was 0.0%, and EVT access site complication rate was 2.7%.
CONCLUSIONS: We concluded that percutaneous VA-ECMO decannulation using a combination of intravascular balloon dilation in EVT and the PP appears to be a safe, minimally invasive, and effective procedure.

UNASSIGNED: Tracheostomy is an important procedure for the treatment of severe coronavirus disease-2019 (COVID-19). Older age and obesity have been reported to be associated with the risk of severe COVID-19 and prolonged intubation, and anticoagulants are often administered in patients with severe COVID-19; these factors are also related to a higher risk of tracheostomy. Cricotracheostomy, a modified procedure for opening the airway through intentional partial cricoid cartilage resection, was recently reported to be useful in cases with low-lying larynx, obesity, stiff neck, and bleeding tendency. Here, we investigated the usefulness and safety of cricotracheostomy for severe COVID-19 patients.
UNASSIGNED: Fifteen patients with severe COVID-19 who underwent cricotracheostomy between January 2021 and April 2022 with a follow-up period of ≥ 14 days were included in this study. Forty patients with respiratory failure not related to COVID-19 who underwent traditional tracheostomy between January 2015 and April 2022 comprised the control group. Data were collected from medical records and comprised age, sex, body mass index, interval from intubation to tracheostomy, use of anticoagulants, complications of tracheostomy, and decannulation.
UNASSIGNED: Age, sex, and days from intubation to tracheostomy were not significantly different between the COVID-19/cricotracheostomy and control/traditional tracheostomy groups. Body mass index was significantly higher in the COVID-19 group than that in the control group (P = 0.02). The rate of use of anticoagulants was significantly higher in the COVID-19 group compared with the control group (P < 0.01). Peri-operative bleeding, subcutaneous emphysema, and stomal infection rates were not different between the groups, while stomal granulation was significantly less in the COVID-19 group (P = 0.04).
UNASSIGNED: These results suggest that cricotracheostomy is a safe procedure in patients with severe COVID-19.

BACKGROUND: Tracheostomy 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.
METHODS: Eight 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.
RESULTS: Tracheal 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.
CONCLUSIONS: The 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.

BACKGROUND: The aim of the study was to assess the feasibility of a standardized tracheostomy decannulation protocol in patients with prolonged tracheostomy referred to a rehabilitation hospital.
METHODS: This prospective cohort study recruited conscious patients with prolonged tracheostomy who were referred to the pulmonary rehabilitation department of a tertiary rehabilitation hospital between January 2019 and December 2021. A pulmonary rehabilitation team used a standardized tracheostomy decannulation protocol developed by the authors. The primary outcome was the success rate of decannulation. Secondary outcomes included decannulation time from referral and reintubation rate after a follow-up of 3 months.
RESULTS: Of the 115 patients referred for weaning from mechanical ventilation and tracheostomy decannulation over the study period, 80.0% (92/115) were finally evaluated for tracheostomy decannulation. The mean time of tracheostomy in patients transferred to our department was 70.6 days. After assessment by a multidisciplinary team, 57 patients met all the decannulation indications and underwent decannulation. Fifty-six cases were successful, and 1 case was intubated again. The median time to decannulation after referral was 42.7 days. Reintubation after a follow-up of 3 months did not occur in any patients.
CONCLUSIONS: A standardized tracheostomy decannulation protocol implemented by a pulmonary rehabilitation team is associated with successful tracheostomy decannulation in patients with prolonged tracheostomy. Not every tracheostomy patient must undergo upper airway endoscopy before decannulation. Tolerance of speaking valve continuously for 4 h can be used as an alternative means for tube occlusion. A swallow assessment was used to evaluate the feeding mode and did not affect the final decision to decannulate.
