High-flow nasal cannula oxygen therapy versus noninvasive ventilation for elderly chronic obstructive pulmonary disease patients after extubation: a noninferior randomized controlled trial protocol

IntroductionNoninvasive ventilation (NIV) is widely used for sequential extubation in patients with chronic obstructive pulmonary disease (COPD). However, NIV may cause many adverse events such as claustrophobia, facial skin compression, air leakage, bloating, and even reflux aspiration, resulting in poor patient compliance/tolerance and high failure rate, especially for older adults who are at high risk of communication difficulties and consciousness disorder. High-flow nasal cannula (HFNC) oxygen therapy is a new alternative support to NIV, but whether it can effectively reduce the rate of re-intubation after extubation in elderly patients with COPD remains controversial. The purpose of this study is to explore the safety and efficacy of HFNC versus NIV for elderly COPD patients after extubation.Methods and analysisThis study is an investigator-initiated, single-center, prospective, non-inferior, randomized controlled trial. Elderly patients (age > 65 years) who have received invasive ventilation and was diagnosed with COPD will be randomly assigned to HFNC group or NIV group immediately after extubation with a planned enrollment of 168 patients. The primary outcomes will be reintubation rates at 72 h and 7 days after extubation. Secondary outcomes will include treatment failure, post-extubation vital signs and arterial blood gases, the scores of compliance and comfort of patients, duration of respiratory support after extubation, respiratory support related adverse events, sleep quality scores, usage of sedative and analgesic drugs after extubation, and the incidence of delirium. Additionally, clinical outcomes such as ventilator-free days at 28 days post-randomization, tracheotomy rate, duration of intensive care unit (ICU) and hospital stay, ICU and hospital mortality will be evaluated.Ethics and disseminationThis study has been approved by the Ethics Committee of West China Hospital of Sichuan University (2023–2284). Informed consent is required. It is expected that a follow-up randomized controlled trial will be conducted. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.Trial registrationThe study was retrospectively registered at ClinicalTrials.gov (ChiCTR2400087312).

Unilateral arytenoid chondroplasty combined with minimally invasive mucosal flap plasty for bilateral vocal cord paralysis--clinical analysis of 66 cases

Objective: To analyze the efficacy of unilateral arytenoid chondroplasty combined with minimally invasive mucosal flap plasty in the management bilateral vocal cord paralysis. Methods: A total of 66 patients with bilateral vocal cord paralysis hospitalized in the First Hospital of Sun Yat-sen University from January 2018 to December 2023 were retrospectively analyzed, among whom there were 8 males and 58 females, with ages ranging from 35 to 86 years old(mean age (57.8±11.6) years). All patients underwent suspension laryngoscopic CO2 laser unilateral arytenoid chondroplasty and mucosal flap under general anesthesia. Postoperative follow-up period extended from 6 months to 6 years, with a median duration of 28 months. The study compared the degree of dyspnea and voice quality (subjective and objective evaluation) of the patients pre- and post-operatively, and analyzed the clinical differences between patients with and without preoperative or intraoperative tracheotomy, the extubation rate of tracheotomized patients, the recurrence rate, and the complication rate. Continuous variables conforming to normal distribution were tested by t-test and categorical variables by χ² test,the Wilcoxon rank-sum test was used to analyze the improvement in dyspnea before and after surgery. Results: Compared with the preoperative period, 59 patients showed improvement in postoperative dyspnea (U=161.5, P<0.01); there was no significant difference in voice disorder index 10, subjective auditory-perceptual assessment, and maximal vocalization time (P>0.05), all of which remained within the relative normal range. Tracheotomy was performed in 32 out of 66 patients, with predominantly degree Ⅲ- dyspnea (46.9%, 15/32), including 26 patients with preoperative tracheotomy and 6 patients with intraoperative tracheotomy. Among the 34 patients who did not undergo tracheotomy, the majority presented with degree Ⅱ-dyspnea (82.4%, 28/34). All patients achieved successful extubation following surgery, with a mean median time to extubation of 1 month. Conclusions: The combination of unilateral arytenoid chondroplasty and minimally invasive mucosal flap plasty represents a refined and effective therapeutic approach for bilateral vocal cord paralysis. This minimally invasive technique has the potential to reduce the rate of tracheotomy.

Clinical risk factors associated with the need for tracheostomy in traumatic cervical and high thoracic spinal cord injury

BackgroundOur objective was to assess the association of completeness and level of spinal cord injury (SCI) with the need for tracheostomy and identify additional risk factors predictive of tracheostomy. MethodsThis was a retrospective review of patients with SCI between January 2017 and December 2022. ResultsPatients with complete SCI were roughly thirty-three times more likely to have a tracheostomy when compared to incomplete injury (82 ​% vs 12 ​%, p ​< ​0.001, OR ​= ​32.9). The rate of tracheostomy did not differ between spinal cord levels for complete (p ​= ​0.68) or incomplete (p ​= ​0.08) injuries. Penetrating injury, low GCS, high ISS, and polytrauma were associated with tracheostomy need in incomplete SCI. ConclusionComplete injury was statistically significantly associated with the need for tracheostomy while level of injury failed to reach significance. Patients with incomplete SCI that have certain clinical risk factors should be considered for early tracheostomy.

Rates of tracheostomy in patients with complex skeletal dysplasia: A 32-year institutional experience

ObjectiveRespiratory failure secondary to multilevel airway compromise may present complex airway challenges in patients with specific skeletal dysplasia diagnoses. This study sought to identify and characterize subgroups of skeletal dysplasia diagnoses that more frequently undergo operative airway evaluations and tracheostomy placement. MethodsRetrospective electronic medical record review of pediatric patients with an ICD-10 associated skeletal dysplasia diagnosis and CPT-specified airway intervention at a tertiary pediatric hospital from 1990 to 2022. Patients without a defined skeletal dysplasia diagnosis, subjects with craniosynostosis syndromes, and those with limited clinical data were excluded. Collected variables included demographics, age at diagnosis, comorbidities, operative procedures, and airway interventions. Descriptive statistical analysis was utilized to evaluate data distribution. ResultsFrom the initial population of 313 patients, 41 subjects were confirmed to have clinical features and/or genetic testing consistent with a skeletal dysplasia diagnosis. A tracheostomy was placed in 19/41 subjects and these patients’ records were further analyzed. Skeletal dysplasia groups with more frequent tracheostomy placement included Filamins and related disorders, Sulfation disorders, and Chondrodysplasia punctata. In the patients with a tracheostomy, skeletal dysplasia was diagnosed at a median age of 0.3 years (IQR 4.8 years), and tracheostomy was initiated at a median age of 1.8 years (IQR 2.2 years). Only four of these patients were successfully decannulated, and two subjects are deceased. ConclusionOver 32 years, nearly half of the skeletal dysplasia patients who underwent airway interventions eventually had a tracheostomy placed. Respiratory insufficiency and complex airway management challenges are common manifestations of skeletal dysplasia.

Intensive Care Unit Transfer in Patients With Deep Neck Infections.

Background: Deep neck infection (DNI) involves the deep neck spaces and may lead to airway compromise. An intensive care unit (ICU) is a specialized unit of the hospital that provides intensive care. ICU care is required for patients with severe DNI, although the risk factors for need of ICU care in patients with DNI have not been investigated. Methods: The clinical and laboratory parameters of 350 patients aged >18 years who were diagnosed with DNI between October 2018 and October 2023 were evaluated. Of these patients, 62 were transferred to the ICU. Univariate and multivariate analyses were applied to assess the risk factors for need of ICU care. Results: Univariate analysis revealed that older age [odds ratio (OR) = 1.0324, 95% confidence interval (CI): 1.0155-1.0496, P = .0001], a higher C-reactive protein (CRP) level (OR = 1.0076, 95% CI: 1.0049-1.0103, P < .0001), and blood glucose level (OR = 1.0057, 95% CI: 1.0023-1.0091, P = .0011), involvement ≥3 spaces (OR = 2.2366, 95% CI: 1.2827-3.8998, P = .0046), and mediastinitis (OR = 4.7134, 95% CI: 2.3537-9.4391, P < .0001) were significant risk factors for ICU transfer in patients with DNI. In multivariate analysis, older age (OR = 1.0216, 95% CI: 1.0032-1.0403, P = .0210), higher CRP level (OR = 1.0063, 95% CI: 1.0033-1.0092, P < .0001), and mediastinitis (OR = 2.6103, 95% CI: 1.1974-5.6905, P = .0158) were independent risk factors of ICU transfer in patients with DNI. The ICU group had a longer hospital stay (23.98 ± 8.53 vs 7.44 ± 4.24, P < .0001) and higher rate of tracheostomy (P < .0001) than the non-ICU group. However, there were no significant differences in the rate of incision and drainage open surgery or pathogens between the groups (all P > .05). Conclusions: Elder patients and those with advanced CRP levels and mediastinitis are more likely to be transferred to the ICU, leading to prolonged hospital stays and a higher risk of tracheostomy. Clinicians should assess the patient's need for ICU transfer and timely manage the airway according to the aforementioned laboratory parameters and complications carefully.

Airway Issues in Management of Severe Cut-Throat Injuries

&amp;lt;i&amp;gt;Introduction:&amp;lt;/i&amp;gt; Open or incised anterior neck injuries inflicted by sharp implements may be described as Cut-throat injuries (CTIs). The managing team is immediately confronted with airway management options, therefore, a close collaboration between the surgeon and the anesthetist is required to adopt a strategy that will guarantee a safe airway and ensure a successful outcome. In this article, we discuss the factors that led us to perform tracheostomy before repair while avoiding a rule of tracheostomy for all. &amp;lt;i&amp;gt;Method:&amp;lt;/i&amp;gt; A prospective study was conducted at Federal Medical Centre, Gusau, between January 2019 -August 2023. Nine (9) patients presented with zone II cut-throat injuries and the choice of airway management was discussed between the surgeon and the anesthetist focused on symptoms of air obstruction and findings within the larynx that could lead to airway obstruction once repair was done. &amp;lt;i&amp;gt;Result:&amp;lt;/i&amp;gt; There were nine patients (9) with the age range of 18-60 years. Tracheostomy rate was 55.6% (n=5). There is a positive correlation (+1) between tracheostomy and laryngeal edema. A subset of patients, 22.2% (n=2) was selected for repair without a tracheostomy. &amp;lt;i&amp;gt;Conclusion:&amp;lt;/i&amp;gt; The choice of perfect airway management should result from constructive collaboration between the surgeon and the anesthetist. Tracheostomy should be considered in patients with asymptomatic laryngeal edema.

Transoral non-robotic surgery for oropharyngeal squamous cell carcinoma

PurposeThis retrospective cohort study aims to evaluate the clinical, oncological, and functional outcomes of transoral non-robotic surgery for oropharyngeal squamous cell carcinoma (OPSCC). Materials and methodsData from 131 patients with surgically treated OPSCC (2010-2022) were analyzed. Patients who underwent exclusively transoral surgery were included in the study. The surgeries were performed under microscopic or endoscopic guidance and either a CO2 laser or an ultrasound/radiofrequency scalpel was used as a cutting instrument, depending on the characteristics and location of the tumor. Functional outcomes were assessed in terms of length of hospital stay, tracheostomy rate, duration of feeding tube dependency and complications. Survival outcomes were assessed in terms of overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS). ResultsOf 74 included patients, transoral surgery demonstrated safety with no major complications. Tracheotomy was performed in 51.4 % of cases, and was maintained for a median of 10 days. Complete swallowing recovery was restored in 97.3 % of cases, after a median of 5 days. The median length of hospital stay was 12 days. At 5 years, OS was 68.2 %, PFS was 58.2 % and DSS was 83.6 %. ConclusionThe study confirms the safety and efficacy of a transoral approach for OPSCC. Having the capability to utilize and access a variety of tools provides the opportunity to tailor the technique to the individual patient and specific circumstances.

Survival Outcomes of Transoral Microsurgery in T3/T4a Laryngeal Tumors: Systematic Review and Meta-Analysis.

To critically evaluate oncological and functional outcomes following transoral laser microsurgery (TLM) in patients with T3/T4a glottic and supraglottic squamous cell carcinoma (SCC). A comprehensive search of five major databases-PubMed, Embase, Scopus, ScienceDirect, and Web of Science-was conducted using a combination of relevant keywords and MeSH terms. Systematic review and meta-analysis of odds ratio (OR), hazards ratio (HR), and proportion, focusing on oncological and functional outcomes of TLM in advanced T3/T4a glottic and supraglottic tumors. A random-effects meta-analysis model was employed. The review incorporated 29 cohort studies, representing a total of 1,897 patients undergoing TLM for T3/T4a glottic and supraglottic SCC. The cumulative 5-year disease-free survival (DFS) rate for T3 glottic and supraglottic tumors was 44.4% (95% CI: 47-66%) and 62.8% (95% CI: 63-81%), while the 5-year DFS for T4 glottic and supraglottic tumors was 41.1% (95% CI: 33.4-49.2%) and 32.9% (95% CI: 19.3-50.1%), respectively. T3 glottic tumors exhibited a 2.5-fold significantly higher odds of local recurrence post-TLM compared to their T3 supraglottic tumors (95% CI: 1.6-3.9, p < 0.0001). Laryngeal preservation rates for T3glottic and supraglottic tumors were 68.9% (95% CI: 48.7-83.8%) and 88.4% (95% CI: 79.4-93.8%), respectively. Both groups showed comparable rates of tracheostomy (p = 0.48) and gastrostomy performed (p = 0.17). This meta-analysis suggests that TLM is a viable larynx preservation approach in select patients with T3/T4a glottic and supraglottic tumors. However, glottic tumors may have less favorable outcomes after TLM compared to those with advanced supraglottic tumors. N/A Laryngoscope, 2024 Laryngoscope, 2024.

Ultrasound Diaphragmatic Assessment as a Predictor of Successful Non-Invasive Mechanical Ventilation in Patients with Acute Exacerbation COPD: an Observational Study

Abstract Background Non-invasive ventilation (NIV) is successful as first-line treatment for patients admitted to hospital with hypercapnic respiratory failure due to AECOPD. Significant diaphragmatic muscle dysfunction (DD) exits in different disease-related and physiological conditions, including COPD. Ultrasonography is considered as a non- invasive and bedside method and commonly applied in intensive care unit (ICU) to assess diaphragmatic function. Objective To demonstrate the value of diaphragmatic ultrasound assessment for patients with AECOPD undergoing NIMV. Patients and Methods A population of 24 consecutive patients with AECOPD admitted to Ain Shams University Hospitals’ Intensive Care units (ICU) were enrolled. Change in diaphragmatic thickness fraction (ΔDTF) &amp;lt; 20% and diaphragm excursion&amp;lt; 10 mm during tidal volume was the predefined cut-off for identifying DD. Correlations between ΔDTF &amp;lt; 20%, diaphragm excursion&amp;lt; 10 mm and NIV failure and other clinical outcomes were investigated. Results 24 cases with AECOPD, 33.3% of them (8 cases) had diaphragm dysfunction (DD+) but after NICPAP 2 cases improved and only 6 cases remain with DD and 16 Patients without DD (DD−). DD+ patients had a higher risk for NIV failure than DD−patients (p &amp;lt; 0.011), and this finding was significantly associated with higher in-hospital, and 30-day mortality rates; longer mechanical ventilation duration; higher tracheostomy rate; and longer ICU stay. Conclusion AECOPD patients with diaphragmatic dysfunction as diagnosed by US showed higher incidence of NIMV failure, longer MV, ICU length of stay, In- hospital mortality, ICU and MV duration were significantly longer in group with DD. Insignificant difference was found considering mortality after 30 days in patients with or without diaphragm dysfunction.

A perioperative predictive model of early mortality in acute cervical spinal cord injury: A prospective cohort study

BackgroundTraumatic cervical spine injury is common among spinal cord injury which requires an intensive, multidisciplinary approach which can affect the immediate postoperative hospital survival rate. By identifying the risk factors leading to early mortality in cervical spine trauma patients, the prognosis of patients with TCSCI can be better predicted. ObjectiveThe study aims to analyze the variables influencing in-hospital mortality in cervical spine trauma patients treated at a Level I trauma Center. MethodsProspective study was conducted on subaxial cervical spine injuries from July 2019 to March 2022. Patients were divided into two groups: Group A, with in-hospital mortality, and Group B, who got discharged from hospital, and mortality predictors were reviewed and analyzed for as potential risk factors for in-hospital mortality. ResultsOut of 105 patients, 83.8 % were male with mean age of 40.43 ± 12.62 years. On univariate analysis, AIS (p-value: <0.01), ICU stay (p-value: <0.01), level of injury (p-value: <0.01), and MRI parameters like the extent of Parenchymal damage (p-value: <0.01), MSCC (p-value: <0.01), and MCC (p-value: <0.01) were potential risk factors for in-hospital mortality. On multivariate regression analysis AIS at presentation (p-value: 0.02) was the only significant independent parameter for in-hospital mortality. ConclusionsAIS grading at presentation, duration of ICU stay, level of injury, rate of tracheostomy, and MRI parameters like the extent of parenchymal damage, MCC, and MSCC influence and predicts in-hospital mortality, whereas AIS is the only independent risk factor.

Evaluating high-flow oxygen therapy after mechanical thrombectomy under general anesthesia in acute ischemic stroke: A retrospective single-center study

BackgroundThe use of mechanical thrombectomy for acute intracranial vascular occlusion under general anesthesia with endotracheal intubation is well-established as a safe and effective method. However, the process of extubation post-surgery presents challenges for certain patients. This retrospective study assesses the safety and efficacy of combining mechanical ventilation with high-flow oxygen inhalation as an interim strategy, while also examining its impact on long-term clinical outcomes. MethodsThis research enrolled 119 patients with acute intracranial large vessel occlusion who underwent mechanical thrombectomy under general anesthesia with tracheal intubation between January 2020 and November 2023. Participants were categorized into two groups: Group 1 (n=55), which received high-flow oxygen (HFO) post-extubation, and Group 2 (n=64), which was treated with routine oxygen supplementation (RO). The study compared reintubation and tracheotomy rates between these groups to determine safety and effectiveness. Additionally, it analyzed long-term clinical outcomes by comparing NIHSS and mRS scores before treatment and at 90-day follow-up. ResultsThe reintubation rate post-extubation was significantly lower in the HFO group (12.7 %, n=7) compared to the RO group (31.2 %, n=20, p=0.016). The incidence of tracheotomy within 7 days was also reduced in the HFO group compared to the RO group (7.3 %, n=4 vs 20.3 %, n=13, p=0.043). Moreover, a greater proportion of patients in the HFO group achieved mRS scores of 0–2 at 90 days post-stroke than those in the RO group (60 %, n=33 vs 40.6 %, n=26, p=0.035). The median NIHSS score at 90 days was more favorable in the HFO group than in the RO group (6, IQR [1–18] vs 8, IQR [1–20], p=0.005). ConclusionThe study suggests that high-flow oxygen therapy after mechanical thrombectomy under general anesthesia with tracheal intubation may lessen the need for reintubation and tracheotomy, potentially leading to improved long-term prognosis.

Determining Extracorporeal Membrane Oxygenation Outcomes in Obese Patients with ARDS

Extracorporeal membrane oxygenation (ECMO) is crucial for managing acute respiratory distress syndrome (ARDS) refractory to conventional therapy, but its impact on obese ARDS patients remains inadequately understood due to relative contraindications per the Extracorporeal Life Support Organization (ELSO) guidelines. This study aimed to analyze the association between obesity and ECMO outcomes in ARDS patients. Using five years of National Inpatient Sample data (2016–2020), we identified ARDS patients through ICD-10 codes, classifying those with a BMI &gt; 30 as obese. Univariate and multivariate analyses were performed to assess mortality, rates of left ventricular assist devices, and tracheostomy differences between obese and non-obese patients, with secondary outcomes examining the impact of obesity on length of stay (LOS) and total hospitalization charges (TOTCHG). Among 3,219 ARDS patients requiring ECMO, 8.2% were obese. While initial univariate analysis showed a non-significant 43% lower mortality odd in obese patients, adjusting for confounders revealed a statistically significant 46% lower odd of mortality compared to non-obese patients (adjusted odds ratio 0.54, 95% confidence interval 0.3-0.94, p 0.032). LOS and TOTCHG did not significantly differ between the two groups, nor did the rates of LVAD or tracheostomy. These findings suggest that obesity may confer a survival advantage in ARDS patients undergoing ECMO, potentially due to factors such as nutritional reserves and the obesity paradox observed in critical illnesses. Therefore, BMI alone should not preclude obese patients from ECMO treatment, emphasizing the need for further research to inform clinical decision-making in this population.

Definition, risk factors, and outcome analysis of prolonged mechanical ventilation in children.

This study aims to explore the time threshold for defining prolonged mechanical ventilation (PMV) in children, along with its risk factors and outcomes. A prospective cohort study was conducted on children aged 29 days-18 years, who were consecutively admitted to two Pediatric Intensive Care Units (PICUs) at Children's Hospital of Chongqing Medical University, from October 2020 to June 2021. The study included patients receiving mechanical ventilation (MV) for more than 2 days (each day >6 h). Participants were divided into five groups based on the duration of MV (2-7 days, 8-14 days, 15-21 days, 21-30 days, >30 days) to compare rates of extubation failure, all-cause mortality one month post-discharge, incidence of ventilator-associated pneumonia, tracheotomy rates, total hospital stay, PICU stay, and overall hospital costs. The most clinically and statistically significant outcome variables were selected. The Youden index was used to determine the MV duration with the most significant impact on overall outcomes, defining this as PMV. Baseline characteristics, treatment information, and outcomes were compared between PMV and non-PMV groups. Univariate and multivariate logistic regression analyses were used to identify risk factors for PMV occurrence. A total of 382 subjects were included in the study. The distribution of children across the five MV duration groups was 44.2%, 27.7%, 10.7%, 8.9%, and 8.4% respectively. The rates of at least one extubation failure in each group were 5.9%, 10.4%, 41.5%, 41.2%, and 46.9% (p < .05). Statistically significant differences were observed among groups in terms of tracheotomy rates, all-cause mortality at 1 month postdischarge, median total hospital stay, median PICU stay, and hospital costs (p < .05). Defining PMV, the most appropriate time point calculated was 12.5 days, based on at least one extubation failure and/or death within 1 month postdischarge. Higher PIM-3 scores, weight for age <-2SD, admission for respiratory distress/insufficient ventilation and/or hemodynamic instability/shock/arrhythmia, noninvasive ventilation on the first day, and undergoing blood transfusion treatment were identified as risk factors for PMV (p < .05). In children, MV for ≥13 days significantly increases mortality rates, extubation failure and tracheotomy rates, duration of PICU and total hospital stay and costs. We suggest defining PMV as MV ≥13 days, particularly for children undergoing MV for respiratory illnesses. This definition can assist clinicians in developing appropriate treatment strategies by focusing on risk factors and providing reliable prognostic consultation to patients' families.

Risk factors for delayed extubation after pediatric perineal anaplasty in patients less than 1 year of age: a retrospective study

BackgroundAnorectal malformation is a common congenital problem occurring in 1 in 5,000 births and has a spectrum of anatomical presentations, requiring individualized surgical treatments for normal growth. Delayed extubation or reintubation may result in a longer intensive care unit (ICU) stay and hospital stay, increased mortality, prolonged duration of mechanical ventilation, increased tracheostomy rate, and higher hospital costs. Extensive studies have focused on the role of risk factors in early extubation during major infant surgery such as Cardiac surgery, neurosurgery, and liver surgery. However, no study has mentioned the influencing factors of delayed extubation in neonates and infants undergoing angioplasty surgery.Materials and MethodsWe performed a retrospective study of neonates and infants who underwent anorectal malformation surgery between June 2018 and June 2022. The principal goal of this study was to observe the incidence of delayed extubation in pediatric anorectal malformation surgery. The secondary goals were to identify the factors associated with delayed extubation in these infants.ResultsWe collected data describing 123 patients who had anorectal malformations from 2019 to 2022. It shows that 74(60.2%) in the normal intubation group and 49(39.8%) in the longer extubation. In the final model, anesthesia methods were independently associated with delayed extubation (P < 0.05).ConclusionWe found that the anesthesia method was independently associated with early extubation in neonates and infants who accepted pediatric anorectal malformation surgery.

Effects of mechanical insufflation-exsufflation on ventilator-free days in intensive care unit subjects with sputum retention; a randomized clinical trial.

Mechanical insufflation-exsufflation (MI-E) facilitates extubation. However, its potential to reduce the duration of ventilator use remains unclear. Therefore, the present study investigated whether the use of MI-E shortened the duration of mechanical ventilation in patients with high sputum retention. A randomized open-label trial was conducted at a single intensive care unit (ICU) in Japan between November 2017 and June 2019. Ventilated subjects requiring suctioning at least once every hour due to sputum retention were randomly assigned to the MI-E group or conventional care group. The primary endpoint was the number of ventilator-free days on day 28. Secondary endpoints were ventilator days in surviving subjects, the length of ICU stay, and mortality and tracheostomy rates among survivors. Forty-eight subjects (81% males) with a median age of 72 years (interquartile range [IQR], 65-85 years) were enrolled. There were 27 subjects in the MI-E group and 21 in the control group. The median number of ventilator-free days was 21 (IQR, 13-24) and 18, respectively (IQR, 0-23) (P = .38). No significant differences were observed in the ICU length of stay (median, 10 days (IQR, 7-12) vs 12 days (IQR, 6-15); P = .31), mortality rate (19% vs 15%; odds ratio [OR], 1.36 [0.28-6.50]; P = .69), or tracheostomy rate among survivors (14% vs 28%; OR, 0.40 [0.08-1.91]; P = .25). In ventilated subjects in the ICU with high sputum retention, the use of MI-E did not significantly increase the number of ventilator-free days over that with conventional care.

Advanced Respiratory Failure Requiring Tracheostomy-A Marker of Unfavourable Prognosis after Heart Transplantation.

Advanced respiratory failure with tracheostomy requirement is common in heart recipients. The aim of the study is to assess the tracheostomy rate after orthotopic heart transplantation and identify the subgroups of patients with the highest need for tracheostomy and these groups' association with mortality at a single centre through a retrospective analysis of 140 consecutive patients transplanted between December 2012 and July 2018. As many as 28.6% heart recipients suffered from advanced respiratory failure with a need for tracheostomy that was performed after a median time of 11.5 days post-transplant. Tracheostomy was associated with a history of stroke (OR 3.4; 95% CI) 1.32-8.86; p = 0.012), previous sternotomy (OR 2.5; 95% CI 1.18-5.32; p = 0.017), longer cardiopulmonary bypass time (OR 1.01; 95% CI 1.00-1.01; p = 0.007) as well as primary graft failure (OR 6.79; 95% CI2.93-15.71; p < 0.001), need of renal replacement therapy (OR 19.2; 95% 2.53-146; p = 0.004) and daily mean SOFA score up to 72 h (OR 1.50; 95% 1.23-1.71; p < 0.01). One-year mortality was significantly higher in patients requiring a tracheostomy vs. those not requiring one during their hospital stay (50% vs. 16%, p < 0.001). The need for tracheostomy in heart transplant recipients was 30% in our study. Advanced respiratory failure was associated with over 3-fold greater 1-year mortality. Thus, tracheostomy placement may be regarded as a marker of unfavourable prognosis.

Management Challenges And Outcome Of Juvenile Onset Respiratory Papillomatosis In A Tertiary Hospital In North Central Nigeria: A Preliminary Study

Background/Aim: Juvenile Onset Recurrent Respiratory Papillomatosis (JoRRP) is a benign tumour attributed to human papillomavirus infection with a high propensity to recur despite appropriate treatment. It is relatively rare but the commonest benign tumour of the larynx in children. This study is aimed at evaluating its management challenges.&#x0D; Materials and methods: This was a retrospective review of patients with JoRRP at Ear, Nose and Throat (ENT) Department, University of Ilorin Teaching Hospital over a 7-year period. The patients' biodata, mode of presentations, surgical care, histopathological findings and management outcome were reviewed.&#x0D; Results: A total number of ten patients were diagnosed with JoRRP during the study period. Male to female ratio was 1:1. All the children were delivered per vaginal and sixty percent were first children of their mothers. Hoarseness, breathy voice and worsening difficulty in breathing were the presentation in 7 (70%) of cases, while 3 (30%) presented with only hoarseness and breathy voice. They all presented first to General Practitioners and Paediatricians before ENT Specialist assessment and six (60%) patients presented to ENT department 6 months or more after the onset of symptoms. They all had direct laryngoscopy and excisional biopsy of laryngeal papillomatous lesions. Thirty percent had tracheostomy done. There is a statistical significant relationship between tracheostomy rate and recurrence rate of JoRRP.&#x0D; Conclusion: JoRRP is a rare but potentially life-threatening benign tumor of the respiratory tract. Most of our patients presented late and were misdiagnosed at presentation. The key to good management outcome remains early diagnosis, adequate management and regular follow-up.

Comparing Simulation Training of Bronchoscopy-Guided Percutaneous Dilatational Tracheostomy Using Conventional Versus 3D Printed Simulators (TRAC-Sim Study).

Background: Individual implementation rate of bronchoscopy-guided percutaneous dilatational tracheostomy (PDT) varies among intensivists. Simulation training (ST) can increase the safety of medical procedures by reducing stress levels of the performing team. The aim of this study was to evaluate the benefit of ST in PDT regarding procedural time, quality of performance, and percepted feelings of safety of the proceduralist and to compare conventional simulators (CSIM) with simulators generated from 3D printers (3DSIM). Methods: We conducted a prospective, single-center, randomized, blinded cross-over study comparing the benefit of CSIM versus 3DSIM for ST of PDT. Participants underwent a standardized theoretical training and were randomized to ST with CSIM (group A) or 3DSIM (group B). After ST, participants' performance was assessed by two blinded examiners on a porcine trachea regarding time required for successful completion of PDT and correct performance (assessed by a performance score). Percepted feelings of safety were assessed before and after ST. This was followed by a second training and second assessment of the same aspects with crossed groups. Results: 44 participants were included: 24 initially trained with CSIM (group A) and 20 with 3DSIM (group B). Correctness of the PDT performance increased significantly in group B (p < .01) and not significantly in group A (p = .14). Mean procedural time required for performing a PDT after their second ST compared to the first assessment (p < .01) was lower with no difference between group A and group B and irrespective of the participants' previous experience regarding PDT, age, and sex. Moreover, percepted feelings of safety increased after the first ST in both groups (p < .001). Conclusions: ST can improve procedural skills, procedural time, and percepted feelings of safety of the proceduralist in simulated PDT.

Trends in the Incidence of Bronchopulmonary Dysplasia after the Introduction of Neurally Adjusted Ventilatory Assist (NAVA).

This study investigates the difference in the rates of bronchopulmonary dysplasia in very low birth weight infants before and after the introduction of neurally adjusted ventilatory assist (NAVA). A retrospective cohort study comparing rates of Bronchopulmonary dysplasia (BPD) before and after implementation of NAVA. Eligibility criteria included all very low birth weight VLBW neonates needing ventilation. For analysis, each cohort was divided into three subgroups based on gestational age. Changes in the rate of BPD, length of stay, tracheostomy rates, invasive ventilator days, and home oxygen therapy were compared. There were no differences in the incidence of BPD in neonates at 23-25 6/7 weeks' and 29-32 weeks' gestation between the two cohorts. A higher incidence of BPD was seen in the 26-28 5/7 weeks' gestation NAVA subgroup compared to controls (86% vs. 68%, p = 0.05). No significant difference was found for ventilator days, but infants in the 26-28 6/7 subgroup in the NAVA cohort had a longer length of stay (98 ± 34 days vs. 82 ± 24 days, p = 0.02), a higher percentage discharged on home oxygen therapy (45% vs. 18%, respectively, p = 0.006), and higher tracheostomy rates (3/36 vs. 0/60, p = 0.02), compared to the control group. The NAVA mode was not associated with a reduction in BPD when compared to other modes of ventilation. Unexpected increases were seen in BPD rates, home oxygen therapy rates, tracheostomy rates, and the length of stay in the NAVA subgroup born at 26-28 6/7 weeks' gestation.

Surgical stabilization of rib fractures for flail chest: Analysis of center-based variability in practice and outcomes.

Given the lack of high-quality data on patient selection for surgical stabilization of rib fractures (SSRF), significant variability in practice likely exists across trauma centers. We aimed to determine whether centers with a more liberal approach to SSRF had improved outcomes. We performed a retrospective cohort study of adult patients with flail chest admitted to Level I or II trauma centers participating in the American College of Surgeons' Trauma Quality Improvement Program. The primary outcome was hospital mortality; secondary outcomes included discharge status, tracheostomy, duration of mechanical ventilation, and hospital length of stay. Logistic regression was performed to calculate center-level observed/expected rates of SSRF and centers were grouped into quintiles from "most liberal" to "most restrictive." Multivariable regression was used to determine the association between these quintiles and outcomes. We also used an instrumental variable analysis to evaluate the association between SSRF and mortality at the patient level. Among 23,619 patients with flail chest across 354 centers, 22% underwent SSRF. Center rates of fixation ranged from 0% to 88%. Higher rates of SSRF were not associated with lower mortality overall (highest vs. lowest quintile: odds ratio, 0.86; 95% confidence interval, 0.63-1.17). However, centers with a more liberal approach to SSRF had lower rates of independent status at discharge, higher tracheostomy rates, longer duration of mechanical ventilation, and longer hospital and ICU length of stay. The patient level analysis demonstrated that SSRF as was associated with a 25% lower risk of death. Overall, centers with a liberal approach to SSRF do not show improved outcomes among patients with a flail chest, but have higher resource utilization. Results at the patient level suggest that there is a population likely to benefit but these patients remain to be identified through further research. Prognostic and Epidemiological; Level III.
