A prospective study of all unplanned adult extubations was conducted for 4 months period in four intensive care units (ICUs) of a community hospital. Our objective was to document the incidence of unplanned extubations, discern possible variables predictive of occurrence and outcome, and formulate preventive measures and guidelines for reintubation. ⋯ Our data suggested that self-extubation is relatively rare in our institution and that about half of self-extubated patients were reintubated. Staff vigilance, a proper weaning period, and the nasal method of intubation were some of the factors to which we attributed this low occurrence rate. However, a larger patient study population is required to show conclusively effective preventive measures and establish guidelines for reintubation.

Comparative Study
Unplanned extubation. Predictors of successful termination of mechanical ventilatory support.
Unplanned extubation (self-extubation or accidental extubation) occurs commonly in mechanically ventilated patients, and many patients do not receive mechanical ventilation indefinitely. Unfortunately, weaning parameters are often unavailable in the setting of unplanned extubation, and it would be useful to define pre-extubation respiratory and ventilatory parameters that predict which patients require reintubation. ⋯ Reintubation after unplanned extubation should not be considered mandatory. Patients who require reintubation have significantly higher preextubation FIo2 and ventilatory requirements than patients who remain extubated.

The incidence and nature of and the outcome following adverse events were studied prospectively in a surgical intensive care unit over a period of 1 year. From a total of 657 patients, 229 (34.8%) suffered 369 adverse events. The number of adverse events per patient ranged from 1 (58.1%) to a maximum of 4 (6.1%). ⋯ There was no significant difference in mortality between patients with single or multiple events. Twenty-two patients died as a direct result of the event, the commonest reason being loss of airway control. Adverse events contribute significantly to mortality in critically ill patients.

Patterns of prescribing and administering drugs for agitation and pain in patients in a surgical intensive care unit.
To describe the variety of medications prescribed along with the doses administered and routes of administration, and to delineate the clarity of orders written and the accuracy of transcription of drugs used for sedation, anxiety, pain, and neuromuscular blockade in a surgical intensive care unit (ICU). ⋯ A wide variety of sedatives and analgesics are frequently used in surgical ICU patients. These agents are often ordered on an "as-needed" basis using a range of doses, sometimes without adequate directions about the indication for their use. Daily doses received are significantly less than their maximum allowable daily doses. Orders for these medications are sometimes transcribed and charted incorrectly. In contrast, neuromuscular blocking agents are not commonly prescribed. Future studies are needed to improve order writing of these agents, and to determine the criteria used by physicians and nurses in the selection and administration of these agents, the outcomes of therapy, and the most cost-effective regimen.
