To examine the validity of a disposable, colorimetric end-tidal CO2 detector in verifying endotracheal tube (ETT) placement in infants and children. ⋯ The detector accurately identifies ETT position in children with spontaneous circulation who weigh more than 2 kg. During CPR, a positive test correctly indicates that the ETT is in the airway, but a negative result (suggesting esophageal placement) requires an alternate means of confirming ETT position.

Complications of endotracheal intubation and mechanical ventilation in infants and children.
To assess the frequency of complications of endotracheal intubation and mechanical ventilation. ⋯ Complications were related to the duration of intubation and mechanical ventilation.

As a referral centre for cervical spine injuries, we have routinely performed awake tracheal intubation when intubation was indicated. A retrospective case control study was undertaken to review the frequency of neurological deterioration and aspiration associated with our approach. Neurological deterioration was assessed by a change in level of injury or neurological grade at admission and discharge. ⋯ This occurred despite a greater injury severity score in the case group. No evidence of aspiration during intubation was documented. We conclude that awake tracheal intubation is a safe method of airway management in patients with cervical spine injuries.

Use of continuous transtracheal oxygen delivery systems combined with rhythmic chest compressions can provide excellent oxygenation and ventilation during cardiopulmonary resuscitation. However, occasional displacement of the transtracheal catheter results in life-threatening pneumomediastinal complications. We investigated using the pharyngeal lumen of a pharyngeal-tracheal lumened airway (PtL) as an alternative delivery system for continuous oxygen flow in 21 large mongrel dogs. ⋯ Successful resuscitation was achieved in 8 of 11 (73 percent) animals, which is similar to the results in historical controls with endotracheal intubation. No pneumomediastinal complications were seen with use of the PtL. We conclude that using the pharyngeal lumen of the PtL for continuous delivery of oxygen combined with external chest compressions can provide a safe and effective mode of oxygenation and ventilation during cardiac arrest.

Resolution of laryngeal injury following translaryngeal intubation.
Translaryngeal intubation (TLI) causes mucosal ulcerations of the vocal cords and posterior laryngeal commissure. Usually these ulcers heal by primary reepithelialization, but occasionally laryngeal granulomas or strictures develop at these ulcer sites. The incidence of granuloma and stricture formation and the variables influencing abnormal laryngeal healing following TLI are not well understood. ⋯ Laryngeal symptoms, particularly hoarseness, resolved as the larynx healed. Performance of tracheostomy, age, TLI for more than 10 days, and severe laryngeal injury at extubation did not influence the median time to resolution of laryngeal abnormalities. Abnormal laryngeal healing following TLI is uncommon but is not exacerbated by prolonged TLI (more than 10 days), severe laryngeal injury at extubation, or performance of a tracheostomy.
