Abstract Background Unanticipated difficult airway remains a challenge for the anesthesiologist with no established standard criteria to predict difficulty in intubation. Our aim was correlate pre-anesthetic ultrasonographic (USG) assessment parameters Cormack-Lehane (CL) grade at direct laryngoscopy view under general anaesthesia. This prospective, observational study on 150 adult patients bet...

BACKGROUND/AIM Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope. MATERIALS AND METHODS A total of 80 obstetric patients were divided into 2 groups, orotracheally intubated with either the McGrath video laryngoscope or ...

Submit Manuscript | http://medcraveonline.com Society of Anaesthesiologist [1]. Video laryngoscopes have high percentages of Cormack-Lehane grades 1 and 2 in patients with predicted difficult airways and high successful intubation rate [2]. It is indicated for intubation in awake patient when there are suspected difficult conventional laryngoscopy and intubation or difficult bag and mask ventil...

TREC’s Spam Filtering Track (Cormack & Lynam, 2005) introduces a standard testing framework that is designed to model a spam filter’s usage as closely as possible, to measure quantities that reflect the filter’s effectiveness for its intended purpose, and to yield repeatable (i.e. controlled and statistically valid) results. The TREC Spam Filter Evaluation Toolkit is free software that, given a...

In his seminal work of 1981, A M Cormack has established that Radon transforms defined on two remarkable families of curves in the plane are invertible and admit explicit inversion formulas via circular harmonic decomposition. A sufficient condition for finding larger classes of curves enjoying the same property is given in this paper. We show that these generalized Cormack’s curves are given b...

This study evaluated the ability of prehospital providers who had no previous training in intubation, to use an Airtraq laryngoscope to intubate a manikin model of a Cormack and Lehane grade III/IV view. Volunteers attending the Australian College of Ambulance Professionals conference, Adelaide, in November 2006 received approximately 5 min of Airtraq training. First-time intubation success rat...

A 63-yr-old woman was anaesthetized for sub-total thyroidectomy. The thyroid gland was large, deviating the trachea to the right and causing 30% tracheal narrowing at the level of the suprasternal notch. Mask ventilation was easy but laryngoscopy was Cormack and Lehane grade 3. Despite being able to see the tip of the epiglottis, tracheal intubation was impossible. An intubating laryngeal mask ...

The discharge of spent sulfite liquor (SSL), the waste water produced during cellulose manufacture, into water courses often results in massive slime infestations of Sphaerotilus natans. Though a considerable amount of work has been done on the stimulation of Sphaerotilus in mixed populations, the most notable probably being that of Amberg and Cormack (1), very little (6) is known about the nut...
