The Usefulness of Design of Experimentation in Defining the Effect Difficult Airway Factors and Training Have on Simulator Oral,Tracheal Intubation Success Rates in Novice Intubators

ACADEMIC EMERGENCY MEDICINE, Issue 4 2010
Frank Thomas MD
Abstract Objectives:, This exploratory study examined novice intubators and the effect difficult airway factors have on pre- and posttraining oral,tracheal simulation intubation success rates. Methods:, Using a two-level, full-factorial design of experimentation (DOE) involving a combination of six airway factors (curved vs. straight laryngoscope blade, trismus, tongue edema, laryngeal spasm, pharyngeal obstruction, or cervical immobilization), 64 airway scenarios were prospectively randomized to 12 critical care nurses to evaluate pre- and posttraining first-pass intubation success rates on a simulator. Scenario variables and intubation outcomes were analyzed using a generalized linear mixed-effects model to determine two-way main and interactive effects. Results:, Interactive effects between the six study factors were nonsignificant (p = 0.69). For both pre- and posttraining, main effects showed the straight blade (p = 0.006), tongue edema (p = 0.0001), and laryngeal spasm (p = 0.004) significantly reduced success rates, while trismus (p = 0.358), pharyngeal obstruction (p = 0.078), and cervical immobilization did not significantly change the success rate. First-pass intubation success rate on the simulator significantly improved (p = 0.005) from pre- (19%) to posttraining (36%). Conclusions:, Design of experimentation is useful in analyzing the effect difficult airway factors and training have on simulator intubation success rates. Future quality improvement DOE simulator research studies should be performed to help clarify the relationship between simulator factors and patient intubation rates.

Comparison of the Cobalt Glidescope® video laryngoscope with conventional laryngoscopy in simulated normal and difficult infant airways,

MICHELLE WHITE MB ChB DCH FRCA
Summary Aim:, To evaluate the new pediatric Glidescope® (Cobalt GVL® Stat) by assessing the time taken to tracheal intubation under normal and difficult intubation conditions. We hypothesized that the Glidescope® would perform as well as conventional laryngoscopy. Background:, A new pediatric Glidescope® became available in October 2008. It combines a disposable, sterile laryngoscope blade and a reusable video baton. It is narrower and longer than the previous version and is available in a greater range of sizes more appropriate to pediatric use. Methods:, We performed a randomized study of 32 pediatric anesthetists and intensivists to compare the Cobalt GVL® Stat with the Miller laryngoscope under simulated normal and difficult airway conditions in a pediatric manikin. Results:, We found no difference in time taken to tracheal intubation using the Glidescope® or Miller laryngoscope under normal (29.3 vs 26.2 s, P = 0.36) or difficult (45.8 and 44.4 s, P = 0.84) conditions. Subjective evaluation of devices for field of view (excellent: 59% vs 53%) and ease of use (excellent: 69% vs 63%) was similar for the Miller laryngoscope and Glidescope®, respectively. However, only 34% of participants said that they would definitely use the Glidescope® in an emergency compared with 66% who would be willing to use the Miller laryngoscope. Conclusions:, The new Glidescope® performs as well as the Miller laryngoscope under simulated normal and difficult airway conditions. [source]

A prospective, randomised, cross-over trial comparing the EndoFlex® and standard tracheal tubes in patients with predicted easy intubation

Summary We aimed to determine if using the EndoFlex® tracheal tube on the first intubation attempt provided improved placement times and intubation success compared with a standard-type tracheal tube in 50 patients undergoing gynaecological surgery in a prospective, randomised, cross-over trial. We found that using the EndoFlex resulted in shorter intubation times (mean (SD) 14.8 (9.7) vs 30.1 (30.5) s), easier intubation (VAS, median (range) 10 (0,70) vs 20 (0,100)), and an increased rate of successful insertion at the first attempt; all p < 0.001. Flexing the distal tip of the EndoFlex was used in 18 patients. There were reductions in the use of external laryngeal pressure, advancement of laryngoscope blade and increased lifting force when intubating with the EndoFlex. Furthermore, patients with a grade 2 (19/50) or 3 (6/50) laryngoscopic view had shorter intubation times, easier intubation and reduced insertion attempts with the EndoFlex. The EndoFlex is a satisfactory alternative to a standard-type tracheal tube, even with an anterior larynx. [source]

The effect of single use laryngoscopy equipment on illumination for tracheal intubation,

Summary We measured the illumination generated by all 30 Macintosh size 3 laryngoscopes in our department with a lux-meter and a standardised laryngoscope holding tube. We found a large range in illumination generated (65,3130 lx). We then measured the effect on the illumination for each laryngoscope by covering the blade with a cover (LaryGard). In every case, the illumination was reduced by the LaryGard, the mean (SD) reduction was 67 (19)%. When we compared the illumination generated by a disposable laryngoscope blade with the same power source, we found that the illumination was reduced less than with the standard Macintosh covered by a LaryGard.

Evaluation of the disposable Vital ViewÔ laryngoscope

apparatus
The Vital ViewÔ laryngoscope (Vital Signs, NJ, USA) consists of a plastic disposable blade containing a fibrelight and a non-disposable handle; there is therefore no need to sterilise the blade and no concern about disintegration of the fibrelight. In a random cross-over design, we compared the Vital View laryngoscope with a conventional metal fibrelight laryngoscope (Welch Allyn, NY, USA) in 100 patients. The Vital View laryngoscope produced a brighter field than the metal laryngoscope (p < 0.001), whereas there was no significant difference in the view of the glottis or the success rate of tracheal intubation. In no patient did any problem occur, such as damage to the laryngoscope blade or loss of light during laryngoscopy. In another 10 patients, prevention of light emission from the side of the laryngoscope blade reduced the brightness (p < 0. 01). This indicated that the brightness of the Vital View laryngoscope is produced by light emission not only from the tip of the blade but also from the side of the blade. Therefore, the disposable Vital View laryngoscope can be used as effectively as a conventional non-disposable laryngoscope. [source]

Difficult airway equipment in English emergency departments

T. Morton
The need for tracheal intubation in the emergency department is often unpredictable and precipitous in nature. When compared with the operating room, a higher incidence of difficult intubation is observed. There are currently no accepted guidelines with respect to the stocking of difficult airway equipment in the emergency department. We have conducted a telephone survey to determine the availability of equipment for the management of the difficult airway in English emergency departments. Overall, the majority of units held a curved laryngoscope blade (100%), gum elastic bougie (99%) and surgical airway device (98%). Of alternative devices for ventilation, a laryngeal mask airway was kept by 65% of departments, a needle cricothyroidostomy kit by 63% and an oesophageal-tracheal twin-lumen airway (Combitube) by 18%. Of alternative devices for intubation, fewer than 10% held a retrograde intubating kit, intubating laryngeal mask, bronchoscope or lighted stylet. Seventy-four per cent of departments held an end-tidal carbon dioxide detector. [source]
