Alternative management techniques for the difficult airway: esophageal-tracheal Combitube.
To summarize knowledge about the esophageal-tracheal Combitube in emergency medicine and anesthesia, with special emphasis on uncommon indications. Papers published between August 2003 and July 2004 are reviewed. ⋯ The esophageal-tracheal Combitube is a useful and efficient alternative airway characterized by high success rates in emergency situations. We recommend the use of a laryngoscope for insertion and strict adherence to the manufacturer's guidelines in order to maximize success and minimize potential injury.

The purpose of this review is to examine recent evidence for the management of the difficult airway. ⋯ This review of algorithms for management of the difficult airway strengthens several generally accepted crucial points. What is always needed is expertise, which one can only get and maintain by daily practice.

While there are many predictors of difficult laryngoscopic intubation, they all have a low positive predictive value. Therefore, unanticipated difficult laryngoscopic intubation will likely occur in our day-to-day practice. This review discusses recent developments in alternative airway devices and techniques in addressing these difficulties. ⋯ The evidence to date does not always arm us with the ability to predict a difficult laryngoscopic intubation. Therefore, it is imperative that we equip ourselves with devices and techniques that will help us to maintain effective oxygenation and ventilation in a safe manner in the face of such failure.

Simulators can be used to teach simple technical skills or used in more realistic settings to teach or assess various cognitive/affective skills. Although simulators have become widespread, their use and efficacy in these various areas have not been delineated and are still being explored. This review will discuss the present state of using medical simulation for airway-management training. ⋯ Simulators are here to stay. Presently their usage in teaching psychomotor skills has scientific validity in specific tasks but their efficacy for teaching higher-order cognitive skills is still evolving. Future studies will continue to delineate the usage in different areas by studying the outcome in skills training and retention.

The Williams Airway Intubator, the Ovassapian Airway and the Berman Airway as upper airway conduits for fibreoptic bronchoscopy in patients with difficult airways.
In this article we will summarize the available information on airways that have been suggested to provide a conduit for the bronchoscope in its passage through the upper airway during fibreoptic intubation. ⋯ Though the Williams Airway Intubator and the Berman Oropharyngeal Airway are superior in this role, all the airways discussed here have major deficiencies in their function. Further research is needed in this field to meet the requirements of endoscopists in situations when it is crucial that equipment reliably fulfils its function.
