Comparative Study Observational StudyThe 'Can't Intubate Can't Oxygenate' scenario in pediatric anesthesia: a comparison of the Melker cricothyroidotomy kit with a scalpel bougie technique.
While the majority of pediatric intubations are uncomplicated, the 'Can't intubate, Can't Oxygenate' scenario (CICO) does occur. With limited management guidelines available, CICO is still a challenge even to experienced pediatric anesthetists. ⋯ At level 1, the first attempt success rate was 100% for both devices. Overall CM showed a better success rate than SB; however, both techniques were associated with significant complication rates, which were more pronounced following the scalpel bougie technique.

Difficult airway consultation service for children: steps to implement and preliminary results.
Failed airway management remains one of the most common causes of cardiopulmonary arrest in the pediatric population. Practice guidelines addressing the difficult airway (DAW) in adults provide anesthesiologists a framework for managing the airway during the perioperative period; however, similar consensus guidelines are lacking in the pediatric population. Many of the adverse events associated with difficult pediatric airway management occur outside the perioperative setting and often result in worse outcomes. The lower frequency of DAW management required in children, lesser awareness of pediatric health care professionals about DAW management, and the need for guiding principles led us to develop a DAW consultative service. This report outlines the steps to establish the Difficult Airway Service (DAS) and the initial experiences with this new consultation service. ⋯ In developing the DAS, our goal was to provide a more comprehensive approach to caring for a child with a DAW that included their entire hospital stay and follow-up care. We believe this approach has improved health care professional awareness as well as the safe management of routine and difficult pediatric airway. Additional studies are needed to determine whether measurable changes in morbidity and mortality are observed over time.

Difficult intubation of a 2.4 kg ex premature, suspected Pierre Robin Sequence with upper airway obstruction causing respiratory failure. Multiple failed intubation attempts by an experienced pediatric anesthetist using described techniques and adjuncts. ⋯ By twisting the stylet into a spiral shape, the endotracheal tube was given improved maneuverability that allowed the intubator to place the endotracheal tube tip to the glottis opening. Then by rotating the tube in a clockwise direction it could be manipulated past the vocal cords into the trachea.

The pressure drop across the endotracheal tube in mechanically ventilated pediatric patients.
During mechanical ventilation, the airway pressure (Paw) is usually monitored. However, Paw comprises the endotracheal tube (ETT)-related pressure drop (∆PETT ) and thus does not reflect the pressure in the patients' lungs. Therefore, monitoring of mechanical ventilation should be based on the tracheal pressure (Ptrach ). We systematically investigated potential factors influencing ∆PETT in pediatric ETTs. ⋯ Paw and Ptrach differ considerably (by ∆PETT ) during mechanical ventilation of pediatric patients. The ETTs' ID, tube length, and manufacturer type are significant factors for ∆PETT and should be taken into account when Paw is valuated. For this purpose, Ptrach can be continuously calculated with good precision by means of the Rohrer approximation.

Effect of a neck collar on upper airway size in children sedated with propofol-midazolam combination during magnetic resonance imaging.
Propofol and midazolam are widely used for pediatric magnetic resonance imaging (MRI) sedation. Increasing depth of sedation may be associated with airway obstruction. A neck collar supporting the mandible and maintaining the head in slight extension may be beneficial in maintaining airway patency. ⋯ Application of a soft neck collar in children aged 2-4 years may enhance the retropalatal and retroglossal airway dimensions during pediatric sedation in the supine position.
