The 1991 Fraser Gurd Lecture: evolution of airway control in the management of injured patients.
The evolution of methods for airway control has been an important factor in improving overall trauma care. Many important advances have been made in technique, tubes, and timing. Current methods of airway control are listed in Table 2 and are categorized as emergency or elective. ⋯ The role of differential ventilators in the management of unilateral pulmonary parenchymal injury requires clinical validation. Intravascular membrane oxygenators have been proposed in advanced pulmonary insufficiency in a ventilated patient. Thus, while many important strides have been made in airway management following trauma, there remain great challenges in addressing the persistent problem of systemic hypoxemia after multiple injuries.

To investigate the role of anaesthetic management in early extubation of the trachea in children after closure of a secundum-type atrial septal defect (ASD II), a retrospective chart review for a two-year period was performed. We identified 36 children who underwent surgical repair of an isolated ASD II. In 19 children (53%) the tracheas were extubated in the operating room immediately after surgery and in 17 patients (47%) the tracheas remained intubated and the lungs were ventilated in the Intensive Care Unit. ⋯ Those children in the extubated group had a lower hourly requirement for morphine by infusion (13.6 +/- 5.7 vs 18.2 +/- 5.4 micrograms.kg-1.hr-1) and a shorter stay (20.5 +/- 3.7 versus 29.0 +/- 11.2 hr) in the Intensive Care Unit. Re-intubation of the trachea was not required in any of the children and no deaths occurred. Early extubation after ASD II repair is safe and, given the results of this study, may offer certain advantages over prolonged intubation and ventilation in these children.

The timing of trauma patient intubation is dependent on clinical presentation and clinician judgment. We sought to correlate the timing of intubation with the presenting of physiologic parameters and clinical outcome to identify potential quality assurance audit filters. Patients (n = 82) were grouped by timing of intubation: PREHOSPITAL, paramedic intubation; IMMEDIATE, within 10 minutes of arrival; DELAYED, beyond 10 minutes but within 2 hours of arrival; and NONURGENT, beyond 2 hours or at the time of surgery. ⋯ Patients in the NONURGENT group were older and commonly presented with tachypnea. The survival rate for the NONURGENT group was lower than predicted by the TRISS method (P = .004). A GCS < or = 13 and age greater than 50 years with presenting respiratory rates of more than 25 breaths/min represent potential trauma intubation audit filters.
