Abstract
BACKGROUND Difficult airway remains a great challenge in pediatric anesthesia practice. Previously published data show the prevalence of difficult airways in pediatric population varies in a wide range. However, there is a lack of studies in the Asian region. METHODS This cross-sectional single-center study was conducted in a tertiary pediatric hospital in China from October 2022 to October 2023. The patients who underwent elective surgery under general anesthesia with tracheal intubation were recruited consecutively. Data on patient characteristics, airway assessment, and airway management information were collected. Multivariable logistic regression analysis was performed to detect the independent variables of difficult airway in pediatric patients. RESULTS A total of 18,491 pediatric patients were included in this study. The overall incidence of difficult airways was 0.22%, 39% of whom were unanticipated. Very few previous airway management information was available in the patients presented with a known difficult airway. Patients with younger age, higher American Society of Anesthesiologists (ASA) physical status classification grade, and presented for craniofacial and thoracic surgery were associated with higher incidence of difficult airway. Further multivariable logistic regression analysis revealed that age ≤28 days (OR=50.48), age between 28days and 1 year (OR=6.053), craniofacial surgery (OR=1.81), and thoracic surgery (OR=0.2465) were independent risk factors of increased incidence of difficult airway. CONCLUSIONS Our study showed the prevalence of difficult airways in pediatric surgical patients. Patient characteristics, age, and type of surgery were identified as the independent factors associated with increased occurrence of difficult airways. Unanticipated difficult airway was not unusual in our study population, even for the patients with previous surgical history.

Eur Radiol 2023; 33:7849-7856. [PMID: 37256351 PMCID: PMC10598084 DOI: 10.1007/s00330-023-09757-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Revised: 03/20/2023] [Accepted: 04/26/2023] [Indexed: 06/01/2023]
Abstract
OBJECTIVES Studies have shown that some ultrasonic indicators can predict difficult airways in adults to an extent. However, whether ultrasonic parameters can be used to predict difficult airways in children is unclear. This study investigated the predictive value of several ultrasonic indices for difficult laryngoscopy (DL) in children. METHODS Pediatric patients aged 5 to 12 years who underwent endotracheal intubation under general anesthesia were enrolled. The hyomental distance in the extended position (HMDE), tongue thickness, midsagittal tongue cross-sectional area, tongue width, and distance from skin to epiglottis (DSE) were measured by ultrasound before anesthesia. The study end point was DL. The receiver operating characteristic curve was used to evaluate the predictive value of each parameter. RESULTS Three hundred and ten children were included in the final analysis, and fifteen (4.8%) children had DL. The shortened HMDE assessed by ultrasound could help identify children aged 5 to 12 years with DL (5-8 years: area under the curve (AUC) 0.74, sensitivity 0.88, specificity 0.60; 9-12 years: AUC 0.72, sensitivity 0.71, specificity 0.83). An increased DSE could help identify children aged 5 to 8 years with DL (AUC 0.76, sensitivity 0.88, specificity 0.69). CONCLUSIONS Ultrasonic measurement of the HMDE can be used to predict DL in children aged 5 to 12 years. The DSE measured by ultrasound can be used to predict DL in children aged 5 to 8 years. CLINICAL RELEVANCE STATEMENT The hyomental distance and the distance from skin to epiglottis measured by ultrasound can be used to predict difficult laryngoscopy in children, which can help reduce serious complications caused by unanticipated difficult airways in children during anesthesia. KEY POINTS • Ultrasonic measurement of the hyomental distance in the extended position may be an effective predictor of difficult laryngoscopy in children aged 5 to 12 years. • The distance from skin to epiglottis measured by ultrasound can be used to predict difficult laryngoscopy in children aged 5 to 8 years. • Preoperative airway assessment using ultrasound can be effectively applied in children and has a great application prospect.

Abstract
Airway management is one of the most crucial aspects of neonatal care. The occurrence of a difficult airway is more common in neonates than in any other age group, and any neonatal intubation can develop into a difficult airway scenario. Understanding the intricacies of the difficult neonatal airway is paramount for healthcare professionals involved in the care of newborns. This chapter explores the multifaceted aspects of the difficult neonatal airway. We begin with a review of the definition and incidence of difficult airway in the neonate. Then, we explore factors contributing to a difficult neonatal airway. We next examine diagnostic considerations specific to the difficult neonatal airway, including prenatal imaging. Finally, we review management strategies. The importance of a multidisciplinary team approach and the role of communication and collaboration in achieving optimal outcomes are emphasized.

Abstract
Background Tracheal intubation is the most reliable way of securing an airway. Pediatric airway management is one of the significant challenges, especially for non-pediatric anesthesiologists. Early airway evaluation for detecting difficult intubation and preventing catastrophic events is necessary before anesthesia, especially in children. Objectives Therefore, this study was done to compare some valuable adult predictors in children under two years of age. Methods This prospective descriptive-analytical study was performed on 405 children under two years of age that were referred for elective surgery under general anesthesia with endotracheal intubation in Imam Hossein Hospital, Isfahan. Under sedation in a supine position, we measured items, including age, weight, height, stern omental distance (SMD), mouth opening (MO), neck circumference (NC), acromio-axillo-suprasternal notch index (AASI), and intubation difficulty scale score (IDS). An expert anesthesiologist did laryngoscopy and intubation, and difficult cases were recorded. Results Our study showed that the frequency of difficult intubation with IDS > 4 was %16, and with IDS > 5 was %3. The variables, including age, weight, height, and SMD, significantly predicted difficult intubation. The cut-off points for age < 6 months, weight < 5/9 kg, height < 61 cm, and SMD < 5/3 cm were obtained, respectively. Other variables, such as MO, AASI, NC, and sex, were unreliable predictors for difficult intubation. Conclusions We found that IDS > 4, age< 6-month, weight < 5/9 kg, and SMD < 5/3 cm are predictors for difficult intubation. It is helpful for the anesthesiologist to measure these predictions before anesthesia is started to find who has difficult intubation.

Abstract
Background: The airway of an anesthetized patient should be secured with an artificial airway for oxygenation or ventilation. Pediatrics are not small adults which means they are different from adults both anatomically and physiologically. This study aims to determine the prevalence of difficult airway and its associated factors in pediatric patients who underwent surgery under general anesthesia in referral hospitals of Addis Ababa. Methods: A multi-centered cross-sectional study design was employed. The bivariable and multivariable logistic regression was used to measure the association between the dependent variable (pediatrics difficult airway) and independent variables. p-value < 0.05 was used to declare statistical significance. Results: A total of 290 pediatrics patients were included in this study. The prevalence of difficult airway in pediatrics patients who underwent surgery was 19.7%. In multivariate logistic regression, pediatrics patients less than 2 years of age (adjusted odds ratio = 6.768, 95% confidence interval = 2.024, 22.636), underweight pediatrics patients (adjusted odds ratio = 4.661, 95% confidence interval = 1.196, 18.154), pediatrics patients having anticipated difficult airway (adjusted odds ratio = 18.563, 95% confidence interval = 4.837, 71.248), history of the difficult airway (adjusted odds ratio = 8.351, 95% confidence interval = 2.033, 34.302), the experience of anesthetists less than 4 years of age (adjusted odds ratio = 9.652, 95% confidence interval = 2.910, 32.050) had a significant association with pediatrics difficult airway. Conclusion: Being pediatric patients less than 2 years of age, underweight pediatrics patients, having anticipated difficult airway, those anesthetists who do not perform enough pediatric cases were identified as the main factors associated with the greater occurrence of difficult airway in pediatric patients.

Abstract
CONTEXT Endotracheal intubation of pediatric patients is challenging, especially in the pre-hospital emergency setting and if performed by less experienced providers. Securing an airway should be achieved with a single intubation attempt, as each intubation attempt contributes to morbidity and mortality. A new airway device, the VieScope, was recently introduced into clinical market, but efficacy to reduced intubation attempts remains unclear thus far. OBJECTIVE We aimed to compare endotracheal intubation by paramedics using the Vie Scope in different pediatric airway simulation conditions. METHODS We conducted a randomized, cross-over simulation study. Following a theoretical and practical training session, paramedics performed endotracheal intubation in 3 different pediatric emergency scenarios: normal airway; tongue edema; cardiopulmonary resuscitation using the VieScope. Overall intubation success rate was the primary outcome. Secondary outcomes included number of intubation attempts, time to intubation, Cormack-Lehane grade, POGO score, and ease of use (using 1-100 scale). RESULTS Fifty-five paramedics with at least 2 years of clinical experience and without any previous experience with the VieScope participated in this study. The overall intubation success rate was 100% in all 3 scenarios. The median intubation time was 27 (24-34) versus 27 (25-37) versus 29 (25-40) s for scenarios A, B, and C, respectively. In scenario A, all paramedics performed successful intubation with 1 single intubation attempt, whereas 2% of the paramedics had to perform 2 intubation attempts in scenario B and 9% in scenario C. CONCLUSIONS Results of this simulation study indicate preliminary evidence, that the VieScope enables adequate endotracheal intubation in the pediatric setting. Further clinical studies are needed to confirm these results.

Abstract
Four basic types of visual aids are used for teaching airway management and decision-making in simulated as well as in real clinical situations: universal algorithms, sets of limited algorithms, concept-based cognitive aids, and checklists. The first three may represent an evolution in the understanding of the role of human error in both successful and failed airway management. Complex visual aids such as the American Society of Anesthesiology difficult airway algorithm may be more useful for teaching, while graphic cognitive aids like the Vortex may be more helpful for decision-making under stress. Not surprisingly, there is a lack of outcome studies, although some cognitive aids have been evaluated in simulation settings.
