Observational StudyA retrospective observational study of acquired subglottic stenosis using low-pressure, high-volume cuffed endotracheal tubes.
The safety of cuffed endotracheal tubes in the neonatal and critically ill pediatric population continues to be questioned due to the theoretical risk of acquired subglottic stenosis. The incidence of acquired subglottic stenosis in the high-risk mixed surgical and medical critically ill pediatric cohort using high-volume, low-pressure cuffed endotracheal tube policy has not yet been described. The aim of our study was to describe and evaluate the use and complication rate of cuffed ETT's in our unit over a 5-year period. ⋯ We report no single case of acquired subglottic stenosis in our cohort that required major surgical correction from a cuffed endotracheal tube during a 5-year period. The introduction of a policy of appropriate placement and maintenance of low-pressure, high-volume cuffed endotracheal tubes in the pediatric critical care unit was not associated with an increased rate of endotracheal tube-related subglottic trauma.

Propofol pharmacokinetic and pharmacodynamic profile and its electroencephalographic interaction with remifentanil in children.
Propofol and remifentanil are commonly combined during total intravenous anesthesia. The impact of remifentanil in this relationship is poorly quantified in children. Derivation of an integrated pharmacokinetic and pharmacodynamic propofol model, containing remifentanil pharmacodynamic interaction information, enables propofol effect-site target-controlled infusion in children with a better prediction of its hypnotic effect when both drugs are combined. ⋯ We have developed an integrated propofol pharmacokinetic-pharmacodynamic model that can describe the pharmacodynamic interaction between propofol and remifentanil for BIS response. An additive interaction was supported by our modeling analysis.

Comparative StudyA retrospective comparison of propofol to dexmedetomidine for pediatric magnetic resonance imaging sedation in patients with mucopolysaccharidosis type II.
Mucopolysaccharidosis type II patients are reported to have an elevated incidence of difficult airway. Propofol is a commonly used sedative for magnetic resonance imaging in pediatric patients, but patients who receive it may exhibit dose-dependent upper airway obstruction and respiratory depression. Dexmedetomidine also provides adequate procedural sedation with a relatively low risk of airway obstruction. Accordingly, we introduced the use of dexmedetomidine in our practice to reduce the risk of airway obstruction during magnetic resonance imaging procedures. ⋯ Dexmedetomidine provides an adequate level of sedation and is associated with lower rates of artificial airway interventions compared to propofol. Therefore, dexmedetomidine may offer advantages for preserving the native airway compared to propofol when administered during magnetic resonance imaging scans in patients with mucopolysaccharidosis type II.

Randomized Controlled TrialComparative evaluation of CMAC and Truview picture capture device for endotracheal intubation in neonates and infants undergoing elective surgeries: A prospective randomized control trial.
Videolaryngoscopy has an established role in difficult airway management in adults. However, there is limited literature to support their efficacy in children. The Truview Picture Capture Device has shown promising results for endotracheal intubation in infants in the past. The CMAC videolaryngoscope has launched its novel infant Miller blade, but its performance has not been assessed clinically for routine intubation in infants and neonates. We hypothesized that the CMAC videolaryngoscope would reduce the total time to intubation as compared to the Truview Picture Capture Device in neonates and infants. ⋯ The CMAC Miller blade reduced the total time taken for tracheal intubation and intubation difficulty as compared to the Truview Picture Capture Device and may be a better tool for intubation in infants.
