Randomized Controlled Trial Clinical Trial
Esophageal tracheal combitube, endotracheal airway, and mask: comparison of ventilatory pressure curves.
The esophageal tracheal Combitube (ETC) is a new airway especially designed for airway maintenance and ventilation in unconscious patients such as those requiring CPR. The ETC may be used as an esophageal obturator or an endotracheal airway. Previous studies yielded a significantly higher mean arterial oxygen tension (PaO2) during ventilation using an ETC in the esophageal position compared to a conventional endotracheal airway (ETA). ⋯ The following differences in intratracheal pressure and flow could be found for ETC when compared to ETA: smaller rising pressure during inspiration, prolonged expiratory flow time, and formation of a small positive end expiratory pressure (PEEP). These factors may be responsible for the improved oxygen tension with ETC. Comparing mask to ETC ventilation, PaO2 did not differ; however, mean arterial carbon dioxide tension was higher during mask ventilation.

The effect of pentobarbital on nitrogen and energy metabolism was evaluated in seven severely head-injured patients (Glasgow Coma Scale 4.7 +/- 1.7) within the first week postinjury. Measured energy expenditure (% of predicted) was significantly lower in the pentobarbital group (n = 4) versus control (n = 3) (76 +/- 23% versus 132 +/- 28%, respectively, p less than 0.01). Similarly, 24-hour urinary nitrogen excretion was lower for the barbiturate group compared to control (11.2 +/- 4.0 gm versus 19.5 +/- 3.3 gm, respectively, p less than 0.01). ⋯ S.). Barbiturate therapy decreases measured energy expenditure and reduces nitrogen excretion without significantly altering 3-methylhistidine excretion in head-injured patients. The metabolic effects of pentobarbital may enable the ability to achieve energy and nitrogen equilibrium during metabolic support of acutely head-injured patients.

We have reviewed the means of transport and type of stabilization used for all patients with acute spinal cord injuries (SCI) transferred to our center since 1985 to determine what effect these variables may have had on change in level of impairment and probability of neurologic improvement after arrival. Sixty-one patients were reviewed, 47 males and 14 females, with a mean age of 34 years. Twenty-five patients (41%) were transported by ground ambulance, 33 (54%) by helicopter, three (5%) by fixed-wing aircraft. ⋯ We conclude that acute SCI patients can be safely transported by air or ground using standard precautions. Distance and extent of associated injury are the best determinants of mode of transport. Skeletal traction does not appear to be a prerequisite for safe, early transfer of SCI patients.

Presented is a case report of a multiple trauma patient whose post-traumatic course was complicated by neuroleptic malignant syndrome triggered by therapeutic haloperidol treatments. Once the syndrome was recognized and treated, a dramatic recovery was achieved.

Multicenter Study Clinical Trial
Preventable trauma deaths in The Netherlands--a prospective multicenter study.
The data of all trauma fatalities occurring in 12 Dutch hospitals during a period of 1 year were reviewed for management errors and preventable deaths by a panel of five surgeons trained in trauma care. Management errors occurred in 38% of the fatalities. There was a significantly higher percentage of management errors in small general hospitals (72%) than in large general (29%) and in university hospitals (34%). ⋯ A significantly higher preventable death rate occurred in small general hospitals (48%), than in large general (14%) and university hospitals (19%). From these results, it can be concluded that management errors and preventable deaths are general phenomena occurring in any hospital. However, they occur significantly more frequently in hospitals not especially equipped to manage severely injured patients.
