Correlating fibreoptic nasotracheal endoscopy performance and psychomotor aptitude

Correlating fibreoptic nasotracheal endoscopy performance and psychomotor aptitude.

We have investigated the correlation between the scores attained on computerized psychometric tests, measuring psychomotor and information processing aptitudes, and learning fibreoptic endoscopy with the videoendoscope. Sixteen anaesthetic trainees performed two adaptive tracking tasks (ADTRACK 2 and ADTRACK 3) and one information management task (MAZE) from the MICROPAT testing system. They th...

Topical anaesthesia of the nasal mucosa for fibreoptic airway endoscopy.

We have compared four methods of topical anaesthesia of the nostril for fibreoptic airway endoscopy in a randomized study with 31 unpremedicated volunteers, each serving as his or her own control. Lignocaine spray, EMLA cream, three cotton swabs soaked in 4% lignocaine solution, or 2% lignocaine gel was applied in a nostril for 3 min. Application of lignocaine spray was rated as the most unplea...

Comparison between Fibreoptic and Blind Nasotracheal Intubation Criteria in Awake Surgical Patients

This work was designed to compare the applicability of awake blind nasal and that of fibreoptic nasotracheal intubation in thirty adult sedated patients (ASA I and II) in whom the trachea planned to be intubated nasally. They were scheduled for elective oral or maxillofacial surgery under general anaethesia. They were randomly assigned into two equal groups according to the method used for intu...

On Correlating Performance Metrics

Performance metrics and their measurements are the basis of identifying and addressing computer performance related issues, from monitoring to capacity planning. IT professionals and performance analysts often face the questions of what metrics to look at, whether those metrics are related, and how to group them in meaningful way for further analysis, e.g., workload characterization. In this pa...
