This study aimed to compare ultrasonography (US) measurements of the upper airway to computerized tomography (CT) measurements. Our study's primary outcome is to research the accuracy of US measurements in the evaluation of upper airway diameters when CT is taken as the gold standard; the secondary outcome is to determine the time required to obtain US measurements. ⋯ The concordance between US and CT measurements is high and the measurements of different practitioners with different experience levels are compatible with each other.

Observational StudyEffectiveness of substantial shortening of the endotracheal tube for decreasing airway resistance and increasing tidal volume during pressure-controlled ventilation in pediatric patients: a prospective observational study.
The endotracheal tubes (ETTs) used for children have a smaller inner diameter. Accordingly, the resistance across ETT (RETT) is higher. Theoretically, shortening the ETTs can decrease total airway resistance (Rtotal), because Rtotal is sum of RETT and patient's airway resistance. ⋯ The laboratory experiment showed that ETT length and the pressure gradient across ETT are linearly related under a certain flow rate, and approximately 40% of the pressure gradient across the ETT at its original length was generated by the slip joint. Median RETT/Rtotal ratio were calculated as 0.69. The effectiveness of ETT shortening on Rtotal and TV was very limited, because the resistance of the slip joint was very large.

The role of WhatsApp™ in pediatric difficult airway management: A study from the PeDI Collaborative.
Management of the pediatric difficult airway can present unique clinical challenges. The Pediatric Difficult Intubation Collaborative (PeDI-C) is an international collaborative group engaging in quality improvement and research in children with difficult airways. The PeDI-C established a WhatsApp™ group to facilitate real-time discussions around the management of the difficult airway in pediatric patients. The goals of this study were to evaluate the patterns of use of the WhatsApp™ group, themes on messages posted on pediatric difficult airway management and to assess the perceived usefulness of the WhatsApp™ group by the PeDI-C members. ⋯ The PeDI-C WhatsApp™ group has facilitated timely knowledge exchange on pediatric difficult airway management across the world. Participants are satisfied with the role the Whatsapp™ group is playing.
