Inhaled sedation is increasing in ICUs, with active carbon filters (ACFs) commonly used for evacuating halogenated gases. However, the potential benefits of a waste anesthetic gas system (WAGS) similar to the ones used in operating rooms should be explored. To limit the suction over the flow sensor where the WAGS is connected on ICU ventilators, an anesthetic gas receiving system (AGRS) is required, constituting with the WAGS an active gas receiving and scavenging system (AGRSS). Ensuring that this whole device does not compromise the flow sensor reliability is crucial. The aim of this study was to compare various gas evacuation devices and assess the reliability of AGRSS on ICU ventilators. ⋯ These findings indicate that using a WAGS with the AGRS system appeared to be reliable for managing gas evacuation in ICUs without compromising pressure or flow delivery. The data from this experimental trial should be confirmed with clinical studies involving human subjects. Given the increasing use of inhaled sedation in ICUs, these results support the daily application of the WAGS with the AGRS for gas evacuation, similar to its established use in anesthesiology.

Unplanned extubation (UE) is the premature or unintended removal of an artificial airway and can cause worse patient outcomes. Study objectives were to describe implementation strategies used to reduce UE in the Hospital for Sick Children neonatal ICU (NICU) and their influence on UE rates, and contributing factors and patient characteristics of infants who had an UE, and compare them between the biological sexes. We hypothesized that the boys would experience more UEs and worse outcomes compared to the girls. ⋯ Detailed well-planned UE reduction strategies significantly reduced the rate of UEs with key factors of success identified. UE characteristics and infant morbidity did not differ between the biological sexes. Infants < 32 weeks of gestational age and with repeated UE had a longer duration of mechanical ventilation and length of stay.

Workforce issues have highlighted the fact that newly graduated respiratory therapists (RTs) need more support during their transition to practice; however, there are few data on best practices for RT residency programs. ⋯ The collected responses showed an increase in a wide range of clinical skills and other soft skills. These results indicate that a respiratory care residency program adds value to the training, overall well-being, and retention of the newly graduated RT.

Tracheostomy bypasses physical barriers that decrease microbial access to the lower airway, which can lead to changes to the lung microbiota. Patients often become chronically colonized with potential pathogens. This study described the incidence and prevalence of specific organisms in a 5-y cohort of children with tracheostomy. ⋯ This retrospective single-site descriptive cohort analysis of pediatric subjects with long-term tracheostomy identified trends in microbial prevalence. The presence of specific bacterial strains was more likely to follow individual subject trajectories than sequential appearance of species. P. aeruginosa was associated with G-tube and Streptococcus species with upper-airway obstruction. Ventilator dependence was not associated with specific microbial profiles.
