Randomized Controlled Trial Comparative Study Clinical Trial
Hemodynamic comparison of direct vision versus blind oral endotracheal intubation.
To determine the hemodynamic response to airway manipulation and endotracheal intubation by comparing the direct oral method of the Macintosh laryngoscope to the blind oral method of the Augustine guide. ⋯ The Augustine guide, a new technique for orally intubating patients blindly and when head and neck manipulations are contraindicated, had less of an effect on HR compared with the Macintosh laryngoscope. Minimal lifting of the tongue and mandible required with the Augustine guide could account for the decreased HR response. The Augustine guide appears to be a promising new addition to the airway armamentarium and deserves further testing.

Randomized Controlled Trial Clinical Trial
Pre-induction skin-surface warming minimizes intraoperative core hypothermia.
To test the hypothesis that only one hour of preinduction skin-surface warming decreases the rate at which core hypothermia develops during the first hour of anesthesia. ⋯ A single hour of preoperative skin-surface warming reduced the rate at which core hypothermia developed during the first hour of anesthesia. Preoperative skin surface warming is particularly helpful during short procedures because redistribution hypothermia is otherwise difficult to treat.

Clinical Trial Controlled Clinical Trial
Epidemiology of the adverse hemodynamic events occurring during "clonidine anesthesia": a prospective open trial of intraoperative intravenous clonidine.
Determine the hemodynamic consequences of intraoperative clonidine during major abdominal surgery. ⋯ IV clonidine can be used routinely during anesthesia for major abdominal surgery.

Multicenter Study
Use of esophageal or precordial stethoscopes by anesthesia providers: are we listening to our patients?
To ascertain current anesthesia utilization of esophageal and precordial stethoscopes in U.S. anesthesia training programs. ⋯ Our data suggest infrequent utilization of esophageal and precordial stethoscopes in anesthesia training institutions. Thus, current anesthesia training may be fostering an environment where providers overlook a valuable minimally invasive, and cost-effective continuous monitor of patients' dynamic vital organ function.

To study whether a detailed radiographic examination of neck and upper airway can help identify normal looking patients in whom endotracheal intubation may be difficult; determine whether such parameters as identified by magnetic resonance imaging (MRI) can also be identified in a soft tissue radiograph; and to study the correlation between oropharyngeal appearance, based on Mallampati's classification, and laryngoscopic findings in a large number of patients requiring endotracheal intubation. ⋯ No significant difference between the two groups could be identified on soft tissue radiography or MRI scans.
