Review
OBJECTIVE
To investigate whether implementation of a multidisciplinary airway team was associated with improvement in (1) rate of successful airway securement at first attempt; (2) time to secure airway; and (3) overall complication rate in patients with a difficult airway, as compared with usual care.
DATA SOURCES
Ovid Medline, Embase, Scopus, Cochrane Central, and CINAHL databases.
REVIEW METHODS
Systematic review of literature on inpatient multidisciplinary team management of difficult airways, including all studies performed in inpatient settings, excluding studies of ventilator weaning, flight/military medicine, EXIT procedures, and simulation or educational studies. DistillerSR was used for article screening and risk of a bias assessment to evaluate article quality. Data was extracted on study design, airway team composition, patient characteristics, and clinical outcomes including airway securement, complications, and mortality.
RESULTS
From 5323 studies screened, 19 studies met inclusion criteria with 4675 patients. Study designs included 12 quality improvement projects, 6 cohort studies, and 1 randomized controlled trial. Four studies evaluated effect of multidisciplinary difficult airway teams on airway securement; all reported higher first attempt success rate with team approach. Three studies reported time to secure the difficult airways, all reporting swifter airway securement with team approach. The most common difficult airway complications were hypoxia, esophageal intubation, hemodynamic instability, and aspiration. Team composition varied, including otolaryngologists, anesthesiologists, intensivists, nurses, and respiratory care practitioners.
CONCLUSION
Multidisciplinary difficult airway teams are associated with improved clinical outcomes compared to unstructured emergency airway management; however, studies have significant heterogeneity in team composition, algorithms for airway securement, and outcomes reported. Further evidence is necessary to define the clinical efficacy, cost-effectiveness, and best practices relating to implementing difficult airway teams in inpatient settings.

Review
Lower urinary tract symptoms represent a significant public health problem worldwide, impairing patients' quality of life, especially in elderly people. Among LUTS, nocturia is assessed as the most experienced entity related to several disorders such as sleep disorders and/or obstructive sleep apnea syndrome (OSAS). Among OSAS patients, nocturia stands as a bothersome symptom that increases alongside with the OSAS severity. However, despite the nocturia and OSAS shared a long-acknowledged link, the causes, and the pathophysiology for development of nocturia in OSAS have remained largely unexamined. Generally, the patients with OSAS experienced nocturia due to easy waking or increased bladder filling. However, nor the effect of treatment on management of nocturia in OSAS patients are well-established.

Meta-Analysis
STUDY OBJECTIVE
This meta-analysis aimed at identifying the risk factors for and their strengths in predicting difficult mask ventilation (MV) through a systematic approach.
DESIGN
Meta-analysis of observational studies.
SETTING
Operating room.
INTERVENTION
Airway- or patient-related risk factors for difficult MV reported in over 20% of eligible studies identified through literature review.
PATIENTS
Adults receiving anesthetic induction with requirement of MV.
MEASUREMENTS
Databases including EMBASE, MEDLINE, Google Scholar, and Cochrane Library were searched from inception to July 2022. The primary outcomes were the identification of commonly reported risk factors for MV and a comparison of their strengths in difficult MV prediction, while the secondary outcomes were the prevalence of difficult MV in the general population and those with obesity.
MAIN RESULTS
Meta-analysis of 20 observational studies involving 335,846 patients identified 13 risk factors with predictive strengths (all p < 0.05): neck radiation (OR = 5.0, five studies, n = 277,843), increased neck circumference (OR = 4.04, 11 studies, n = 247,871), obstructive sleep apnea (OSA) (OR = 3.61, 12 studies, n = 331,255), presence of beard (OR = 3.35, 12 studies, n = 295,443), snoring (OR = 3.06, 14 studies, n = 296,105), obesity (OR = 2.99, 11 studies, n = 278,297), male gender (OR = 2.76, 16 studies, n = 320,512), Mallampati score III-IV (OR = 2.36, 17 studies, n = 335,016), limited mouth opening (OR = 2.18, six studies, n = 291,795), edentulous (OR = 2.12, 11 studies, n = 249,821), short thyroid-mental distance (OR = 2.12, six studies, n = 328,311), old age (OR = 2, 11 studies, n = 278,750), and limited neck movement (OR = 1.98, nine studies, n = 155,101). The prevalence of difficult MV was 6.1% (16 studies, n = 334,694) and 14.4% (four studies, n = 1152) in the general population and those with obesity, respectively.
CONCLUSIONS
Our results demonstrated the strengths of 13 most common risk factors for predicting difficult MV, which may serve as an evidence-based reference for clinicians to incorporate into their daily practice.

PURPOSE
Most randomized controlled trials (RCTs) in patients with acute respiratory distress syndrome (ARDS) revealed indeterminate or conflicting study results. We aimed to systematically evaluate between-trial heterogeneity in reporting standards and trial outcome.
METHODS
A systematic review of RCTs published between 2000 and 2019 was performed including adult ARDS patients receiving lung-protective ventilation. A random-effects meta-regression model was applied to quantify heterogeneity (non-random variability) and to evaluate trial and patient characteristics as sources of heterogeneity.
RESULTS
In total, 67 RCTs were included. The 28-day control-group mortality rate ranged from 10 to 67% with large non-random heterogeneity (I = 88%, p < 0.0001). Reported baseline patient characteristics explained some of the outcome heterogeneity, but only six trials (9%) reported all four independently predictive variables (mean age, mean lung injury score, mean plateau pressure and mean arterial pH). The 28-day control group mortality adjusted for patient characteristics (i.e. the residual heterogeneity) ranged from 18 to 45%. Trials with significant benefit in the primary outcome reported a higher control group mortality than trials with an indeterminate outcome or harm (mean 28-day control group mortality: 44% vs. 28%; p = 0.001).
CONCLUSION
Among ARDS RCTs in the lung-protective ventilation era, there was large variability in the description of baseline characteristics and significant unexplainable heterogeneity in 28-day control group mortality. These findings signify problems with the generalizability of ARDS research and underline the urgent need for standardized reporting of trial and baseline characteristics.

Review
AIM(S)
To systematically locate, evaluate and synthesize evidence regarding effectiveness of interprofessional tracheostomy teams in increasing speaking valve use and decreasing time to speech and decannulation, adverse events, lengths of stay (intensive care unit (ICU) and hospital) and mortality. In addition, to evaluate facilitators and barriers to implementing an interprofessional tracheostomy team in hospital settings.
DESIGN
Systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Johns Hopkins Nursing Evidence-Based Practice Model's guidance.
METHODS
Our clinical question: Do interprofessional tracheostomy teams increase speaking valve use and decrease time to speech and decannulation, adverse events, lengths of stay and mortality? Primary studies involving adult patients with a tracheostomy were included. Eligible studies were systematically reviewed by two reviewers and verified by another two reviewers.
DATA SOURCES
MEDLINE, CINAHL and EMBASE.
RESULTS
Fourteen studies met eligibility criteria; primarily pre-post intervention cohort studies. Percent increase in speaking valve use ranged 14%-275%; percent reduction in median days to speech ranged 33%-73% and median days to decannulation ranged 26%-32%; percent reduction in rate of adverse events ranged 32%-88%; percent reduction in median hospital length of stay days ranged 18-40 days; no significant change in overall ICU length of stay and mortality rates. Facilitators include team education, coverage, rounds, standardization, communication, lead personnel and automation, patient tracking; barrier is financial.
CONCLUSION
Patients with tracheostomy who received care from a dedicated interprofessional team showed improvements in several clinical outcomes.
IMPLICATIONS FOR PATIENT CARE
Additional high-quality evidence from rigorous, well-controlled and adequately powered studies are necessary, as are implementation strategies to promote broader adoption of interprofessional tracheostomy team strategies. Interprofessional tracheostomy teams are associated with improved safety and quality of care.
IMPACT
Evidence from review provides rationale for broader implementation of interprofessional tracheostomy teams.
REPORTING METHOD
PRISMA and Synthesis Without Meta-analysis (SWiM).
PATIENT/PUBLIC CONTRIBUTION
None.

Burn injury is a common cause of trauma. Non-fatal burn injuries are a leading cause of morbidity, and significant numbers of the victims are children. Scar contracture after burn injury can cause severe functional limitation, pain, and aesthetic and psychological problems and patients may present for contracture release and reconstructive surgery. The aim of this systematic review was to identify research relevant to airway management of children with burn contracture of the face and neck with special emphasis on awake airway management and airway anesthesia, and synthesize results that can aid practice. Literature search was performed on Medline, PubMed, Cochrane Library, and Google Scholar with selected keywords. The search was restricted to human subjects of ≤18 year age, there was no language or time restriction, and the final search was concluded in July 2021. The review included 41 articles involving airway management of 56 patients in 61 anesthesia episodes. Patients aged between 8 months to 18 years. Mask ventilation and direct laryngoscopy, video laryngoscopy, optical stylet, supraglottic airway, flexible scope intubation and tracheostomy, and extracorporeal membrane oxygenation were the devices and methods used for securing the airway and oxygenation while the patients were awake or after anesthesia induction. Detailed planning and patient preparation are the fundamentals of airway management of pediatric patients with burn contracture of the face and neck; awake airway management with airway anesthesia can be safely used in selected patients. This review provides information for good clinical practice and might serve to improve the care of such children.

Meta-Analysis Review
A systematic review and meta-analysis of the entire COVID-19 Tracheostomy cohort was conducted to determine the cumulative incidence of complications, mortality, time to decannulation and ventilatory weaning. Outcomes of surgical versus percutaneous and outcomes relative to tracheostomy timing were also analysed. Studies reporting outcome data on patients with COVID-19 undergoing tracheostomy were identified and screened by 2 independent reviewers. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. Outcome data were analysed using a random-effects model. From 1016 unique studies, 39 articles reporting outcomes for a total of 3929 patients were included for meta-analysis. Weighted mean follow-up time was 42.03±26 days post-tracheostomy. Meta-analysis showed that 61.2% of patients were weaned from mechanical ventilation [95%CI 52.6%-69.5%], 44.2% of patients were decannulated [95%CI 33.96%-54.67%], and cumulative mortality was found to be 19.23% [95%CI 15.2%-23.6%] across the entire tracheostomy cohort. The cumulative incidence of complications was 14.24% [95%CI 9.6%-19.6%], with bleeding accounting for 52% of all complications. No difference was found in incidence of mortality (RR1.96; p=0.34), decannulation (RR1.35, p=0.27), complications (RR0.75, p=0.09) and time to decannulation (SMD 0.46, p=0.68) between percutaneous and surgical tracheostomy. Moreover, no difference was found in mortality (RR1.57, p=0.43) between early and late tracheostomy, and timing of tracheostomy did not predict time to decannulation. Ten confirmed nosocomial staff infections were reported from 1398 tracheostomies. This study provides an overview of outcomes of tracheostomy in COVID-19 patients, and contributes to our understanding of tracheostomy decisions in this patient cohort.

Meta-Analysis Review
Extubation failure (EF) is a significant concern in mechanically ventilated newborns, and predicting its occurrence is an ongoing area of research. To investigate the predictors of EF in newborns undergoing planned extubation, we conducted a systematic review and meta-analysis. A systematic literature search was conducted in PubMed, Web of Science, Embase, and Cochrane Library for studies published in English from the inception of each database to March 2023. The PRISMA guidelines were followed in all phases of this systematic review. The Risk of Bias Assessment for Nonrandomized Studies tool was used to assess methodological quality. Thirty-four studies were included, 10 of which were overall low risk of bias, 15 of moderate risk of bias, and 9 of high risk of bias. The studies reported 43 possible predictors in six broad categories (intrinsic factors; maternal factors; diseases and adverse conditions of the newborn; treatment of the newborn; characteristics before and after extubation; and clinical scores and composite indicators). Through a qualitative synthesis of 43 predictors and a quantitative meta-analysis of 19 factors, we identified five definite factors, eight possible factors, and 22 unclear factors related to EF. Definite factors included gestational age, sepsis, pre-extubation pH, pre-extubation FiO, and respiratory severity score. Possible factors included age at extubation, anemia, inotropic use, mean airway pressure, pre-extubation PCO, mechanical ventilation duration, Apgar score, and spontaneous breathing trial. With only a few high-quality studies currently available, well-designed and more extensive prospective studies investigating the predictors affecting EF are still needed. In the future, it will be important to explore the possibility of combining multiple predictors or assessment tools to enhance the accuracy of predicting extubation outcomes in clinical practice.

Meta-Analysis
OBJECTIVE
This study aimed to review and appraise the evidence regarding airway ultrasound assessment in predicting difficult laryngoscopy in adult patients.
DESIGN
A systematic review of the literature was conducted according to the Cochrane collaboration guidelines and the recommendations for the systematic review and meta-analysis of diagnostic studies. Observational studies that evaluated the diagnostic performance of airway ultrasound for the prediction of difficult laryngoscopy were included for consideration.
SETTING
Literature searches were performed in 4 databases (PubMed [Medline], Embase, Clinical Trials, and Google Scholar) to identify all observational studies using any ultrasound technique to assess difficult laryngoscopy. The search terms included "sonography," "ultrasound," "airway," "difficult airway," "difficult laryngoscopy," "Cormack," "risk factors," "ultrasound at the point of care," "difficult ventilation," "difficult intubation" and others, combined with sensitive filters. The search was done for studies performed in the last 20 years in English or Spanish.
PARTICIPANTS
Adult patients older than 18 years old under general anesthesia for an elective procedure. Evident anatomic airway abnormalities, obstetric populations, those using an alternative imaging method besides ultrasound, and animal studies were excluded.
INTERVENTIONS
Preoperative bedside ultrasound measuring distances and ratios from the skin to different reference points, such as the ratio of the hyomental distance in a neutral position (HMDN) and hyomental distance in extension (HMDR), HMDN, and the skin-to-epiglottis distance (SED), the preepiglottic area, and tongue thickness, among others.
MEASUREMENTS AND MAIN RESULTS
A total of 24 studies evaluated the prediction of a difficult laryngoscopy using airway ultrasound. The diagnostic performance and the number of ultrasound parameters reported in the studies were variable. Meta-analysis was performed for 3 measurements consistently included in most studies. The SED and the HMDR ratio presented a sensitivity of 75% and 61%, respectively, and a specificity of 86% and 88%, respectively. The ratio of the preepiglottic distance to the epiglottic distance at the midpoint of the vocal cords (pre-E/E-VC) presented the best performance for predicting a difficult laryngoscopy (sensitivity: 82%, specificity: 83%, diagnostic odds ratio: 22.2).
CONCLUSION
With the currently available evidence, the 3 commonly used point-of-care ultrasound measures used to identify difficult laryngoscopy, (SED, HMDR, and pre-E/E-VC), showed better sensitivity and similar specificity to clinical measures. Future studies and more data may change the authors' confidence in these conclusions, given the wide variability of measurements noted in studies.

Meta-Analysis Review
BACKGROUND
The use of sedative and analgesic drugs during non-invasive ventilation (NIV) in patients with acute respiratory failure (ARF) is controversial.
OBJECTIVES
To assess the clinical effectiveness of sedative and analgesic medications used during NIV for patients with ARF to no sedation or analgesia. In addition, to investigate the characteristics of dexmedetomidine in comparison to other medications.
METHODS
PubMed, Embase, Web of Science, Cochrane Library and China National Knowledge Infrastructure (CNKI) were searched. Mean differences (MDs) or pooled risk ratios (RRs) were computed using random-effects models. We applied the Cochrane risk-of-bias assessment tool 2.0 to assess the methodological quality of eligible studies and the GRADE approach to evaluate the evidence certainty.
RESULTS
Twenty-one studies were selected. Whether in Group A (using sedative and analgesic drugs vs. nonuse) or Group B (using dexmedetomidine vs. other drugs), the rates of tracheal intubation and delirium, the length of NIV, and the length of stay in the intensive care unit (ICU LOS) all decreased in both experimental groups (P < 0.05). And there were no significant differences in all-cause mortality and the incidence of hypotension between the two groups (P > 0.05), while both Group A and Group B's experimental groups had greater incidences of bradycardia.
CONCLUSIONS
Administering sedative and analgesic medications during NIV can reduce the risk of tracheal intubation and delirium. Additionally, dexmedetomidine outperformed other sedative medications in terms of these clinical outcomes, making it the better option when closely monitoring patients' vital signs.
