Twenty-seven anaesthesia faculty, fellows and residents compared a standard intubating mannequin and an anaesthetized pig as models for teaching fibreoptic tracheal intubation. When likened to the clinical situation, the anatomic characteristics of the pig airway were rated as significantly more realistic than the airway characteristics of the mannequin with the exception of the appearance of the epiglottis. In addition, the overall score for the pig model was significantly higher than the score for the mannequin and 26 of 27 evaluators rated the anaesthetized pig as the more effective teaching model. We conclude that an anaesthetized, spontaneously breathing pig is a valid model for teaching fibreoptic endotracheal intubation.

Case ReportsNasotracheal tube obstruction from a central incisor. Report of a case.
After maxillofacial trauma, teeth and other objects can become potential foreign bodies. Whenever possible, careful examination before intubation should be undertaken to avoid serious morbidity secondary to aspiration. The anesthesiologist should be informed and necessary preventive measures taken. This article describes a situation in which this not being done could potentially have led to serious complications.

Prehospital pediatric endotracheal intubation performance review.
Pediatric prehospital care was reviewed over a one-year period to determine success rate, causes of unsuccessful attempts, and complications of performing endotracheal intubation. The Milwaukee County Emergency Medicine Technician-Paramedics (EMT-Ps) responded to 1467 pediatric (less than 19 years of age) patient calls. This accounted for 11% of the patients who received EMT-P care during the study period. ⋯ Common difficulties in intubating the PNB patient included inability to visualize the glottis and cords secondary to mucus and/or vomitus, use of inappropriately small endotracheal tubes, and accidental extubation during transport. Difficulties in intubating impending respiratory failure patients included patient resistance and seizure activity. We recommend that the EMT-P training curriculum include a review of these difficulties and that prehospital pediatric endotracheal intubation performance be monitored and reviewed with the EMT-Ps.

Randomized Controlled Trial Comparative Study Clinical Trial
Successful extubation of newborn infants without preextubation trial of continuous positive airway pressure.
Sixty newborn infants who had been mechanically ventilated through 3.0- or 3.5-mm endotracheal tubes were studied to examine the necessity of a preextubation trial of continuous positive airway pressure (CPAP). Thirty randomly assigned study infants were directly extubated from intermittent mandatory ventilation rates of six per minute; 30 randomly assigned control infants were extubated after a six-hour trial of continuous positive airway pressure of 3 cm H2O. Changes in respiratory rate, in PCO2, and in PO2/FIO2 were similar. ⋯ Five control and no study infants had apneic episodes greater than or equal to 0.5 per hour (chi 2 = 5.5, P less than .02). The results of this study suggest that newborn infants may tolerate direct extubation from low intermittent mandatory ventilation rates without a preextubation trial of CPAP. A preextubation trial of CPAP appears to be unnecessary and may cause more frequent apnea in newborn infants if used for more than several hours.

Comparative Study[Tracheal cannulation technics in cervical vertebral and spinal cord injuries. A comparative study].
Cervical vertebral dislocations and fractures require the complete immobility of the neck until an intervention of stabilization of the spinal cord, by surgery or external means, is performed. Endotracheal intubation, which might represent a harmful operation, can become difficult when the stabilization of the spinal cord has been obtained by external means. ⋯ Each method presents advantages with regard to the grading of visualization of the larynx, but also limitations due to the time required to perform the intubation and the appearance of complications. It seems therefore useful to continue the search for the ideal method for tracheal intubation, which should be absolutely atraumatic, fast, and completely successful.
