Comparative StudyEndotracheal intubation in a medical transport helicopter - comparing direct laryngoscopy with the prototype Storz CMAC videolaryngoscope in a simulated difficult intubating position.
This pilot study examined backward intubation of the Laerdal Difficult Airway Manikin in a medical transport helicopter using the prototype (a new more compact) Storz CMAC videolaryngoscope. The standard manikin airway Cormack Lehane (CL) view scores were 2.00 +/- 1.00 for direct view and 1.375 +/- 0.517 for the indirect view (CMAC). Success rates for backward intubation in the standard airway were 100% (CMAC) and 87.5% (DV). ⋯ The success rates for backward intubation of the difficult airway were 12.5% (DV) and 63% (CMAC). Our results show that in backward intubation of the difficult airway in a helicopter setting, the prototype CMAC videolaryngoscope significantly improved the airway score by 1-2 grades and improved intubation success 5-fold. Studies using the portable CMAC videolaryngoscope under challenging rescue conditions and positions should be considered.

Case ReportsThe videolaryngoscope is less traumatic than the classic laryngoscope for a difficult airway in an obese patient.
This report describes the anesthetic management of an obese patient with a difficult airway and the merits of videolaryngoscopy, specifically in terms of the reduced risk of dental damage during intubation. A 49-year-old woman (body mass index; BMI, 36 kg.m(-2)), was scheduled to undergo an elective laparoscopic cholecystectomy because of cholelithiasis. ⋯ Intubation using a video-assisted Macintosh laryngoscope (V-Mac; Karl Storz, Tuttlingen, Germany) was successful upon the first attempt. The maximum force exerted on the patient's maxillary incisors was 61 N by direct laryngoscopy and 7.6 N using the indirect videolaryngoscope, both using a Macintosh blade.

Endotracheal intubation comparing a prototype Storz CMAC and a glidescope videolaryngoscope in a medical transport helicopter - a pilot study.
In this pilot study, experienced medical helicopter personnel evaluated and compared the prototype Storz CMAC and GlideScope (GS) videolaryngoscopes in intubating a Laerdal Difficult Airway Manikin in a helicopter. No significant differences were found between the devices in the standard airway mode with 100% success rates for the intubations. ⋯ The success rate for intubating the difficult airway was 0% with DV; compared to 63% with the CMAC and 50% with the GS (p = 0.03). The participants answered a post study questionnaire regarding the characteristics of the devices and indicated preference for the CMAC over the GS in intubation of the difficult airway.

The Pentax-AWS videolaryngoscope (Tokyo, Japan) has been used successfully to intubate the trachea in patients with difficult airways. We report the use of the Pentax-AWS for tube exchange in a patient with difficult airway. In a 57-year-old man scheduled for laminectomy of the cervical spines, tracheal intubation of a reinforced tube was accomplished with a great difficulty. ⋯ Under the video image, the cuff of the reinforced tube was deflated, and a tube exchanger was introduced through the polyvinylchloride tube into the trachea, alongside the reinforced tube. The reinforced tube was removed, and the new tube was advanced over the exchanger into the trachea. We suggest that the Pentax-AWS is useful for tube exchange, as one can continuously confirm the entire course of exchange and can detect and rectify any possible problems, such as difficulty in advancing an endotracheal tube over the exchanger.
