Background: Emergency airway management is a crucial and complex procedure frequently performed in the emergency department (ED). Airway contamination usually caused by blood, secretions, and emesis impairs ventilation, reduces successful intubation, and increases the complication rates, leading to difficult laryngoscopy, delayed intubation, and increased mortality rates. One technique employed to decontaminate these airways when standard approaches fail is Suction-Assisted Laryngoscopy and Airway Decontamination (SALAD). Methods: A comprehensive literature search was conducted across PubMed, Cochrane, and Science direct databases following a specific search strategy. All search results were screened in a two-stage process (title–abstract and full-text screening) in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 guidelines. Data from finalized articles were extracted using a standardized excel file developed a priori. Lastly, quality and risk of bias were assessed using appropriate tools according to respective study designs, and data were narratively synthesized. Results: A total of 224 records were identified. Upon screening, seven studies were included consisting of five simulation-based studies and two clinical case reports. Simulation studies reported that SALAD training significantly improved first-pass intubation success (53.7–90.2%), reduced time to intubation (up to 30 s), and enhanced airway visualization. Clinical cases further reported successful first-pass intubation in patients with massive airway contamination without complications. Overall, across both study types, the SALAD technique improved airway management performance, provider confidence, and airway contamination control compared to standard suction techniques. Conclusions: This systematic review highlights the benefits of the SALAD technique by enhancing airway visualization, reinforcing it as a significant tool for contaminated airway management. Trainees who underwent SALAD training demonstrated improved first-pass intubation success, reduced intubation time, and increased operator confidence. While data from the included studies seems promising, most studies are small simulation-based studies with limited clinical outcome data. Given its clinical relevance and educational value, future studies must prioritize high-quality research in clinical environments to establish SALAD’s efficacy and to define its role in integration into prehospital protocols.

Background/Objectives: Recurrent laryngeal nerve injury (RLNI) is a major complication of thyroidectomy, affecting voice, airway protection, and quality of life. Intraoperative nerve monitoring (IONM) has been introduced to complement direct nerve visualization and reduce RLNI risk, but its efficacy remains controversial. This systematic review and meta-analysis aimed to determine RLNI prevalence with IONM, compare rates with historical no-IONM cohorts, perform head-to-head comparisons, and assess the influence of IONM characteristics. Methods: PubMed, Scopus, Web of Science, Cochrane Library, and Google Scholar were searched for studies reporting RLNI rates in thyroidectomy with and without IONM. Pooled prevalence estimates were calculated for transient and permanent unilateral and bilateral RLNI in IONM studies and historical controls. Direct meta-analysis estimated pooled odds ratios (ORs) for RLNI risk reduction. Subgroup analyses examined IONM type, monitoring model, stimulation amplitude, voltage, and neuromuscular blockade use; meta-regression identified influential parameters. Results: A total of 103 studies involving 132,212 patients met the criteria. Unilateral transient RLNI was lower with IONM (4%, 95% CI: 4–5%) than in historical controls (5%, 95% CI: 4–6%), while unilateral permanent RLNI was 1% in both groups. Bilateral RLNI was rare. Direct comparison showed a 38% reduction in transient unilateral RLNI (OR: 0.62, 95% CI: 0.42–0.79) and a 51% reduction in permanent unilateral RLNI (OR: 0.49, 95% CI: 0.34–0.70) with IONM. Continuous IONM, lower stimulation amplitudes (≤2 mA), and avoidance of neuromuscular blockade were protective. Conclusions: IONM significantly reduces RLNI risk, particularly for unilateral injuries, with optimal protection achieved through continuous monitoring, low stimulation amplitudes, and avoidance of neuromuscular blockade.

Background/Objectives: Correct inhalation technique (IT) is crucial in the management of airway obstructive diseases. However, inhaler misuse among patients is frequent. The aim of the study was to assess IT and analyze factors influencing inhalation errors in adults with asthma and COPD. Methods: This single-center case–control study involved 180 adults with asthma or COPD. IT was evaluated using a checklist of common errors, a four-grade dedicated scale, and peak inspiratory flow. Patients with correct and incorrect IT were compared across multiple factors, including demographics, disease duration and severity, motivation for treatment, spirometry results, cognitive function, visual or hearing disorders and prior training in inhaler use. Results: A total of 115 patients with asthma and 65 patients with COPD were analyzed. Among them, only 59 patients (32.8%) were treated with 1 inhaler. Sixty-eight patients (37.8%) used all their inhalers properly. Correct IT was observed more frequently among DPI compared to MDI users (p < 0.001). Only 76 patients (42.2%) reported previous training in IT. No differences were found between correct and incorrect inhaler users (MDI or DPI) regarding age, gender, education, treatment motivation, visual or hearing impairments or cognitive disorders. Among MDI users, those with correct IT more often read the drug leaflet (p = 0.015). Among DPI users, proper technique was associated with better self-assessment (p = 0.046) and a higher rate of prior inhalation training (p = 0.001). Conclusions: Most adults with asthma or COPD do not use their inhalers properly, particularly patients using MDI. Insufficient education in the field of proper IT is still a burning issue.

Background: We present a multidisciplinary training experience based on simulation techniques and critical resource management implemented in the emergency department. Methods: Simulation courses/workshops were conducted with a multidisciplinary team from the Hospital Emergency Department. The timeline for their development includes a preliminary analysis of needs, objectives, and scenario design, development of the simulation course, and finally, areas of implementation. In this last phase, the teaching team prepares a document and/or report/summary of the activity in which, among other things, the aspects with the greatest capacity for improvement or the areas for implementation of safety measures are determined. A total of 112 healthcare professionals (doctors, nurses, and care assistants) participated in this training program. Its design consisted of the following stages: a preliminary analysis of training needs, the establishment of objectives and scenario design, the development of the simulation workshop, and finally, a report on areas for improvement in patient safety identified during the workshop learning process. Results: The workshops enabled us to identify areas for improvement and develop local protocols/recommendations aimed at improving patient safety in the emergency department, such as standardizing a protocol to guide us in managing resources in crisis situations, a protocol for airway management, a protocol for massive transfusion, and a review of the triage process. In addition, we added value by incorporating cognitive aids and visual tools into the standardization of processes. Conclusions: For resource management in this type of crisis in the hospital emergency setting, it is essential to use a debriefing process guided by experienced instructors after a specific experiential learning experience through simulation scenarios. This helps to contextualize and analyze the advantages and disadvantages of general recommendations. Full article

Background: Continuous positive airway pressure (CPAP) effectiveness can be compromised by adverse effects. Despite its potential impact on adherence and sleepiness, aerophagia remains under-recognized and poorly characterized. This ancillary analysis of the InterfaceVent study aimed to identify risk factors for aerophagia in a large real-life cohort of CPAP-treated patients and to assess its association with both CPAP adherence and sleepiness. Methods: InterfaceVent was a prospective, real-life, cross-sectional study. Adults treated for at least 3 months with CPAP were included. Patients self-reported mask-related side effects using visual analogue scales. Aerophagia was defined as a dichotomous outcome based on patient-reported symptoms and CPAP non-adherence as mean nightly usage <4 h. Sleepiness was assessed using Epworth Sleepiness Scale (ESS). Results: A total of 1461 patients (median age 67 years (Q1–Q3; 60–74); 27.6% women) were included. Aerophagia was reported by 8.3% of participants. Compared to patients without aerophagia, those affected were younger, more frequently female, and had lower BMI. Patients with aerophagia reported a median ESS score of 7 (4–10) versus 5 (3–8) for patients without aerophagia (p < 0.001). CPAP usage was significantly lower in the aerophagia group (median 6.37 vs. 6.75 h/day; p = 0.001), whereas non-adherence, did not significantly differ between groups (10.7% vs. 7.5%; p = 0.20). Conclusions: This ancillary analysis of the InterfaceVent study highlights the burden of aerophagia in CPAP-treated patients and identifies modifiable and non-modifiable risk factors. Better recognition and management of this under-reported side effect may improve CPAP adherence and patient comfort. Trial registration: InterfaceVent is registered with ClinicalTrials.gov (NCT03013283). The first registration date is 23 December 2016. Full article

Three-dimensional (3D) modeling and printing technologies are increasingly used in pediatric surgery, offering improved anatomical visualization, surgical planning, and personalized approaches to complex conditions. Compared to standard imaging, patient-specific 3D models—virtual or printed—provide a more intuitive spatial understanding of congenital anomalies, tumors, and vascular anomalies. This review compiles evidence from pediatric surgical fields including oncology, abdominal, and thoracic surgery, highlighting the clinical relevance of 3D applications. The technological workflow—from image segmentation to computer-aided design (CAD) modeling and multimaterial printing—is described, emphasizing accuracy, reproducibility, and integration into hospital systems. Several clinical cases are presented: neuroblastoma, cloacal malformation, conjoined twins, and two cases of congenital diaphragmatic hernia (one with congenital pulmonary airway malformation, CPAM). In each, 3D modeling enhanced anatomical clarity, increased surgeon confidence, and supported safer intraoperative decision-making. Models also improved communication with families and enabled effective multidisciplinary planning. Despite these advantages, challenges remain, such as production time, cost variability, and lack of standardization. Future directions include artificial intelligence-based automation, expanded use of virtual and mixed reality, and prospective validation studies in pediatric cohorts. Overall, 3D modeling represents a significant advance in pediatric precision surgery, with growing evidence supporting its safety, clinical utility, and educational value. Full article

Background: Airway management in patients with obstructive sleep apnea (OSA) presents unique challenges for anesthesiologists and other airway practitioners. This comprehensive review examines current evidence and clinical practices for managing difficult airways in this high-risk population. OSA is characterized by specific anatomical and physiological alterations that increase both the likelihood of encountering difficult intubation and the risk of rapid desaturation during airway manipulation. Methods: Preoperative assessment of OSA patients requires integration of traditional difficult airway evaluation with OSA-specific considerations, including severity indices, oxygen desaturation patterns, and continuous positive airway pressure dependency. Conventional direct laryngoscopy often proves inadequate in these patients, prompting the development and refinement of alternative approaches. Videolaryngoscopy has emerged as a particularly valuable technique in OSA patients, offering improved glottic visualization while maintaining physiologic positioning. Flexible endoscopic techniques, particularly awake flexible bronchoscopic intubation, remain essential for high-risk scenarios, though they require considerable expertise. Results: Recent technological innovations have produced hybrid devices combining multiple modalities to address the specific challenges presented by OSA patients. Adjunctive tools and techniques, including specialized introducers, exchange catheters, and high-flow nasal oxygen, play critical roles in extending safe apnea time and facilitating successful intubation. Professional society guidelines now incorporate OSA-specific recommendations, emphasizing thorough preparation, appropriate device selection, and comprehensive monitoring. Conclusions: Effective management ultimately requires not only appropriate technology but also systematic preparation, strategic device selection, and meticulous execution. As OSA prevalence continues to rise globally, optimizing airway management approaches for this challenging population remains a critical priority for patient safety. Full article

Background/Objectives: Primary malignant lung tumors in children are rare and diagnostically challenging. This study presents a single-center experience in the diagnosis and treatment of these tumors, emphasizing the role of histopathological and genetic profiling in informing individualized therapeutic strategies. Methods: We retrospectively reviewed records of seven pediatric patients (ages 2–18) treated from 2015 to 2025. Diagnostics included laboratory tests, chest CT, bronchoscopy, and histopathological/immunohistochemical analysis. Treatment primarily involved surgical resection, complemented by chemo-, radio-, or targeted therapies when indicated. Results: Inflammatory myofibroblastic tumor (IMT) represented the most commonly diagnosed entity (3/7 cases). The tumors presented with nonspecific symptoms, most frequently dry cough. Tumor type distribution was age-dependent, with aggressive forms such as pleuropulmonary blastoma predominantly affecting younger children, whereas IMT and carcinoid tumors were more common in older patients. Surgical resection remained the mainstay of treatment in the majority of cases. Bronchoscopy served as a valuable adjunct in the initial management of tumors exhibiting intraluminal growth, allowing for direct visualization, tissue sampling, and partial debulking to alleviate airway obstruction. In patients with an initially unresectable IMT harboring specific gene fusion rearrangement (e.g., TFG::ROS1), neoadjuvant targeted therapy with crizotinib enabled adequate tumor shrinkage to allow for subsequent surgical resection. Two patients in the study cohort died as a result of disease progression. Conclusions: A multidisciplinary diagnostic approach—integrating radiologic, bronchoscopic, histopathological, and genetic evaluations—ensures high diagnostic accuracy. While conventional treatments remain curative in many cases, targeted therapies directed at specific molecular alterations may offer essential therapeutic options for selected patients. Full article

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a chronic upper airway disease that may involve different inflammatory endotypes, although in Western populations it is most commonly associated with type 2 inflammation. CRSwNP has a significant impact on the patient’s quality of life. The recommended appropriate medical therapy is effective in controlling CRSwNP symptoms in many patients; however, a subset continues to exhibit persistent type 2 inflammation, evidenced by recurrent nasal polyps, elevated eosinophil counts, or the need for systemic corticosteroids or surgery. Monoclonal antibodies have recently become a novel and personalized treatment that can help refractory patients restore disease control. Objective: The present study aims to evaluate the effectiveness of mepolizumab in real-world settings in a diverse patient population, focusing on assessing the impact of this therapy on patient-reported outcomes after six months of treatment. Methods: This is a multicenter, observational study of CRSwNP patients treated with mepolizumab carried out in five hospitals located in Spain. Adult patients with a diagnosis of uncontrolled CRSwNP were included in the study. The change in the nasal polyp score (NPS) was the main clinical endpoint. Changes in the Sinonasal Outcome Test (SNOT-22), nasal congestion and smell impairment visual analogue scale scores, and blood and nasal polyp tissue eosinophil counts were among other endpoints included. Results: In total, 47 patients were included, and 91% were asthmatic. The nasal polyp score (0–8) was reduced significantly in the cohort (mean change: −2.56, p < 0.0001). The mean SNOT-22 score improved 25.29 points. Nasal congestion (−3.57, p < 0.0001) and smell impairment (−4.0, p < 0.0001) visual analog scale scores (0–10) showed a significant improvement. Blood and tissue eosinophil median counts showed significant reductions versus baseline of 86% and 26%, respectively. Among those patients with asthma, the asthma control test score achieved a median value of 24 points. Conclusions: This study provides real-world evidence supporting the effectiveness of mepolizumab in managing CRSwNP in patients with features suggestive of type 2 inflammation. The observed improvements in patient-reported outcomes, nasal polyp burden, and asthma control suggest that mepolizumab may be a valuable therapeutic option for this patient population. Full article

The use of implants in the trachea is increasing in respiratory diseases as an alternative to address pathological problems with airway obstruction. This article presents the design and development of a three-way cannula and its evaluation in a testbed capable of emulating the human breathing cycle. The new tracheal cannula allows airflow through a third duct (vertical one) towards the vocal folds, enabling phonation. The testbed assesses Total Lung Capacity (TLC) and endotracheal pressure by considering the cannula inside a replica of a trachea. The flow is generated by a mechanism composed of electronic elements, and the implementation of instruments for measuring pressure and lung capacity enables the visual and continuous collection of data. The three-way cannula offers improvements in airway capacity, with an average of up to 1.766 L of airflow and a pressure of 17.083 mbar. The airflow at the upper branch allows for improvement, enabling the patient to phonate even with the implant in place, while preserving patency due to the biocompatibility and elasticity of platinum silicone.

Background: Snoring is a common symptom within the spectrum of sleep-disordered breathing, often occurring independently or in association with obstructive sleep apnea syndrome (OSAS). Despite its prevalence, treatment strategies remain variable and lack standardization, particularly regarding surgical interventions. This review aims to evaluate and summarize the outcomes of soft palate and pharyngeal surgeries for adult snoring based on recent literature. Methods: A systematic review was conducted using the PubMed database, identifying studies published between 2014 and 2024 that involved adult patients undergoing upper airway surgery for snoring. Inclusion criteria required pre- and postoperative snoring assessment using the Visual Analog Scale (VAS). Studies were categorized by surgical technique (anterior vs. lateral/circumferential), anesthesia type, presence of tonsillectomy, BMI, OSAS severity (based on AHI), and use of Drug-Induced Sleep Endoscopy (DISE). Descriptive analysis was performed on the changes in VAS scores. Results: A total of 43 studies involving 2713 patients were included, with 18 eligible for quantitative analysis (716 patients). Across all patients, mean VAS scores improved from 7.29 to 3.50 (ΔVAS 3.79). Both anterior and lateral/circumferential techniques yielded significant symptom reduction (ΔVAS 4.12 and 3.68, respectively). General anesthesia showed slightly better outcomes than local anesthesia. Notably, tonsillectomy was associated with greater symptom improvement (ΔVAS 5.17 vs. 4.49). Patients with lower BMI and milder OSAS showed higher baseline VAS but similar improvements. Limited objective measures and heterogeneity in surgical protocols were key limitations. Conclusions: Surgical interventions for snoring provide subjective symptom relief regardless of surgical approach or OSAS severity. Tonsillectomy may enhance outcomes. Future efforts should prioritize standardized, objective outcome measures and personalized treatment planning, potentially incorporating DISE and wearable acoustic technologies. Full article

Obstructive sleep apnoea (OSA) is a prevalent condition characterised by intermittent upper airway obstruction during sleep, resulting in recurrent hypoxia and sleep fragmentation. Emerging evidence highlights the significant impact of OSA on neuro-ophthalmological health, linking it to conditions such as glaucoma, optic neuropathy, papilledema, and visual field defects. These associations emphasise the importance of understanding the mechanisms connecting OSA to neuro-ophthalmological disorders to enhance early diagnosis and management. This review explores the pathophysiological pathways, including hypoxia-induced vascular dysregulation, oxidative stress, inflammation, and intracranial pressure fluctuations, that contribute to ocular and neurological impairments in OSA patients. Advanced diagnostic tools, such as optical coherence tomography and polysomnography, offer promising avenues for detecting subclinical neuro-ophthalmological changes, enabling timely intervention. Management strategies, primarily centred on continuous positive airway pressure therapy, have shown efficacy in mitigating OSA-related neuro-ophthalmological complications. However, surgical and pharmacological interventions and lifestyle modifications remain vital components of a multidisciplinary approach to care. Despite advancements, significant research gaps persist, particularly in understanding the long-term impact of OSA treatment on neuro-ophthalmological outcomes and identifying specific biomarkers for early detection. Future research should prioritise longitudinal studies, interdisciplinary collaborations, and personalised medicine approaches to address these challenges. Recognising and treating neuro-ophthalmological disorders in OSA patients is imperative for improving quality of life and preventing irreversible visual and neurological damage. Full article

Objectives: This review summarizes current evidence on robotic-assisted upper airway and neck surgery in pediatric patients, highlighting clinical indications, outcomes, limitations, and areas for future research. Methods: A systematic review was conducted in accordance with PRISMA guidelines, including studies on robotic surgery for pediatric patients (≤18 years) with upper airway conditions and cervical pathologies. Data on study characteristics, patient demographics, surgical details, outcomes, and robotic system advantages or limitations were extracted. Results: Twenty studies met inclusion criteria, comprising 104 pediatric patients who underwent 110 robotic procedures, mostly transoral robotic surgery (TORS) for base of tongue, laryngeal, and cervical pathologies. The Da Vinci Si was the most used system. The mean operative time was ~74 min, with minimal blood loss and no intra/post operative tracheostomies. Reported advantages included enhanced visualization, precision, and reduced morbidity. Limitations involved size mismatches, limited working space, and high costs. Follow-up (mean 11.4 months) revealed no recurrences, confirming feasibility and safety in selected pediatric cases. Conclusions: Robotic-assisted surgery appears to be a feasible and safe option for managing pediatric upper airway and neck conditions, offering promising functional and aesthetic outcomes with low complication rates. However, its use is currently limited by anatomical constraints, high costs, and the need for surgeon training. Long-term prospective studies with larger cohorts are needed to confirm its efficacy and define its role compared to traditional techniques. Full article

Therapeutic gene editing strategies utilize endogenous DNA repair pathways—nonhomologous end joining (NHEJ) or homology-directed repair (HDR)—to introduce targeted genomic modifications. Because HDR is restricted to dividing cells, whereas NHEJ functions in both dividing and non-dividing cells, NHEJ-based approaches are better suited for in vivo gene editing in the largely post-mitotic airway epithelium. Homology-independent targeted insertion (HITI), an NHEJ-based method, offers a promising strategy for cystic fibrosis (CF) gene therapy. Here, we applied HITI to drive the expression of a promoterless reporter through an exon trap strategy in both proliferating airway basal cells and well-differentiated primary airway epithelial cultures derived from transgenic ROSA^mTmG ferrets. We also established a versatile human gene editing reporter (GER) airway basal cell line capable of multipotent differentiation, enabling real-time visualization of editing outcomes and the quantitative assessment of HDR- and NHEJ-based editing efficiencies. Together, these platforms provide easily accessible tools for optimizing genome editing strategies in the respiratory epithelium and advancing clinically relevant delivery strategies for CF gene therapy.

Patients with chronic obstructive pulmonary disease (COPD) often experience acute exacerbations characterized by elevated neutrophilic inflammation in the lungs. Currently, this condition is diagnosed through visual inspection of sputum color and volume, a method prone to personal bias and unsuitable for patients who are unable to expectorate spontaneously. In this manuscript, we present a novel approach for measuring and monitoring exhaled myeloperoxidase (MPO), a biomarker of neutrophilic airway inflammation, without the need for sputum analysis. The method involves analyzing an unmodified surgical facemask worn by the patient for 30 min using biosensing decals that transfer antibody-coated nanoparticles. These colloids specifically interact with MPO trapped by the facemask in a dose-dependent manner, enabling the quantification of MPO levels, with a dynamic range up to 3 · 10¹ µg·mL⁻¹. The proposed diagnostic approach successfully differentiated patients with acute exacerbations from stable patients with 100% sensitivity and specificity. Healthy individuals also showed significantly lower MPO levels compared to COPD patients. Our results suggest that facemask analysis could be a non-invasive diagnostic tool for airway diseases, particularly in patients unable to expectorate. Full article
