The perioperative management and dissemination of critical information regarding a patient with an unexpected difficult intubation, including successful application of a difficult airway algorithm (Figure 1), are described. Documentation and dissemination of critical information include entry of patient data into an in-hospital computerized Difficult Airway/Intubation Registry, simultaneous application of a highly visible Difficult Airway/Intubation Patient Wrist Band (coded for access to computer registry), summary reports distributed to health care providers, and enrollment of the patient in the Medic Alert Foundation International's newly established category difficult airway/intubation for 24-hour access. We postulate that the widespread use of the procedures described in this report may reduce the contribution of unexpected difficult airway/intubation to anesthetic morbidity and mortality.

Randomized Controlled Trial Clinical Trial
Midazolam in combination with propofol for sedation during local anesthesia.
To compare the sedative, anxiolytic, and amnestic effects, as well as the recovery characteristics, when midazolam (vs. a placebo) is administered to patients receiving a propofol infusion for sedation during local anesthesia. ⋯ Premedication with midazolam 2 mg IV produced increased sedation, amnesia, and anxiolysis when administered immediately prior to the propofol infusion as part of a sedation technique for outpatient surgery. This combination did not prolong the recovery room stay when compared with propofol alone.

Randomized Controlled Trial Comparative Study Clinical Trial
Intraoperative warming therapies: a comparison of three devices.
To compare the effectiveness of three commonly used intraoperative warming devices. ⋯ The forced-air warmer applied to only a limited skin surface area transferred more heat and was clinically more effective (at maintaining central body temperature) than were the other devices. The characteristic early decrease in central temperature observed in all groups regardless of warming therapy is consistent with the theory of anesthetic-induced heat redistribution within the body.

Randomized Controlled Trial Comparative Study Clinical Trial
Temporal correlation of succinylcholine-induced fasciculations to loss of twitch response at different stimulating frequencies.
The present study was undertaken to determine the time courses of succinylcholine-induced fasciculations and adductor pollicis single-twitch responses at two stimulating frequencies. ⋯ The data reveal that cessation of fasciculations may be an inaccurate clinical sign of the readiness for intubation and confirm that standardized methods of neurostimulation are necessary in the pharmacodynamic evaluation of neuromuscular blocking drugs. In settings where profound neuromuscular relaxation is not required, waiting at least 30 seconds beyond the disappearance of fasciculations should provide good intubating conditions.
