The purpose of this investigation was to investigate the association between first attempt success and intubation-related complications in the Intensive Care Unit after the widespread adoption of video laryngoscopy. We further sought to characterize and identify the predictors of complications that occur despite first attempt success. This was a prospective observational study of consecutive intubations performed with video laryngoscopy at an academic medical Intensive Care Unit. Operator, procedural, and complication data were collected. Multivariable logistic regression was used to examine the relationship between the intubation attempts and the occurrence of one or more complications. A total of 905 patients were intubated using a video laryngoscope. First attempt success occurred in 739 (81.7 %), whereas >1 attempt was needed in 166 (18.3 %). One or more complications occurred in 146 (19.8 %) of those intubated on the first attempt versus 107 (64.5 %, p < 0.001) of those r...

Background. Multiple studies have demonstrated varying rates of successful endotracheal intubation (ETI). Until the application of video laryngoscopy, little information regarding prehospital intubation could be analyzed objectively by individuals other than the provider performing the ETI. Objective. To evaluate the association of variables recorded during video laryngoscopy and successful ETI attempts, defined as placing the endotracheal tube in the trachea. Methods. We retrospectively reviewed intubations performed by a single helicopter emergency medical service (HEMS) using a video larygoscope from March 1, 2010, to October 1, 2010. All videos were de-identified and analyzed by a single researcher. Time intervals (e.g., attempt time) and intubation process variables (e.g., Cormack-Lehane [C-L] view) were abstracted from all videos. Time intervals were begun when the laryngoscope blade passed the lips and entered the oral cavity (entry). We describe variables using means and standard deviations (continuous), medians with interquartile ranges (ordinal), and percentages with 95% confidence intervals (categorical). We then looked at univariate associations between these variables and ETI success using logistic regression. Results. We recorded 116 intubations during the study period. Twenty-nine recordings were either incomplete (n = 26) or of insufficient quality for analysis

; for the Clinical Research in Intensive Care and Sepsis (CRICS) Group IMPORTANCE In the intensive care unit (ICU), orotracheal intubation can be associated with increased risk of complications because the patient may be acutely unstable, requiring prompt intervention, often by a practitioner with nonexpert skills. Video laryngoscopy may decrease this risk by improving glottis visualization. OBJECTIVE To determine whether video laryngoscopy increases the frequency of successful first-pass orotracheal intubation compared with direct laryngoscopy in ICU patients. DESIGN, SETTING, AND PARTICIPANTS Randomized clinical trial of 371 adults requiring intubation while being treated at 7 ICUs in France between May 2015 and January 2016; there was 28 days of follow-up. INTERVENTIONS Intubation using a video laryngoscope (n = 186) or direct laryngoscopy (n = 185). All patients received general anesthesia. MAIN OUTCOMES AND MEASURES The primary outcome was the proportion of patients with successful first-pass intubation. The secondary outcomes included time to successful intubation and mild to moderate and severe life-threatening complications. RESULTS Among 371 randomized patients (mean [SD] age, 62.8 [15.8] years; 136 [36.7%] women), 371 completed the trial. The proportion of patients with successful first-pass intubation did not differ significantly between the video laryngoscopy and direct laryngoscopy groups (67.7% vs 70.3%; absolute difference, −2.5% [95% CI, −11.9% to 6.9%]; P = .60). The proportion of first-attempt intubations performed by nonexperts (primarily residents, n = 290) did not differ between the groups (84.4% with video laryngoscopy vs 83.2% with direct laryngoscopy; absolute difference 1.2% [95% CI, −6.3% to 8.6%]; P = .76). The median time to successful intubation was 3 minutes (range, 2 to 4 minutes) for both video laryngoscopy and direct laryngoscopy (absolute difference, 0 [95% CI, 0 to 0]; P = .95). Video laryngoscopy was not associated with life-threatening complications (24/180 [13.3%] vs 17/179 [9.5%] for direct laryngoscopy; absolute difference, 3.8% [95% CI, −2.7% to 10.4%]; P = .25). In post hoc analysis, video laryngoscopy was associated with severe life-threatening complications (17/179 [9.5%] vs 5/179 [2.8%] for direct laryngoscopy; absolute difference, 6.7% [95% CI, 1.8% to 11.6%]; P = .01) but not with mild to moderate life-threatening complications (10/181 [5.4%] vs 14/181 [7.7%]; absolute difference, −2.3% [95% CI, −7.4% to 2.8%]; P = .37). CONCLUSIONS AND RELEVANCE Among patients in the ICU requiring intubation, video laryngoscopy compared with direct laryngoscopy did not improve first-pass orotracheal intubation rates and was associated with higher rates of severe life-threatening complications. Further studies are needed to assess the comparative effectiveness of these 2 strategies in different clinical settings and among operators with diverse skill levels.

Objectives: The objective was to compare video-assisted laryngoscopy (VAL) to direct laryngoscopy (DL) on success rate and complication rate of intubations performed in a pediatric emergency department (ED). Methods: This is a retrospective cohort study of attempted intubations of children aged 0-18 years in a pediatric ED between 2004 and 2014 with first attempt by an ED provider. In VAL, the laryngoscopist attempts direct visualization of the glottis with a C-MAC video laryngoscope while the video monitor is used for real-time guidance by a supervisor, backup visualization for the laryngoscopist should the direct view be inadequate, and confirmation of endotracheal tube passage through the vocal cords. We performed univariate comparisons of intubations using DL to intubations using VAL on rates of firstpass success, complications, and whether the patient was successfully intubated by an ED provider. We then created a logistic regression model to adjust for provider experience level, difficult airway characteristics, and indications for intubation to compare intubations using DL to intubations using VAL for each outcome. Results: We identified 452 endotracheal intubations of 422 unique patients, of which 445 intubations had a first attempt by an ED provider. Six intubations were excluded due to insufficient information available in the record. Of the included intubations, 240 (55%) were attempted with DL and 199 (45%) with VAL. The overall first-pass success rate was 71% in the DL group and 72% in the VAL group. After adjustment for covariates, the first-pass success rate was similar between laryngoscopy approaches (adjusted odds ratio = 1.23, 95% confidence interval = 0.78 to 1.94). Conclusions: We found no difference between DL and VAL with regard to first-pass intubation success rate, complication rate, or rate of successful intubation by ED providers for children undergoing intubation in a pediatric ED.

Prehospital intubation poses several unique challenges. Video assisted laryngoscopy has been shown to help increase intubation success in the hospital setting; however, little prospective data have examined video assisted laryngoscopy in traditional ground ambulance agencies. We performed a randomized, cross-over, non-blinded trial in ground ambulances comparing first attempt success and overall intubation success between video assisted laryngoscopy using the King Video Laryngoscope (KVL) and direct laryngoscopy (DL). We collected patient and provider demographics along with intubation details. Success rates were compared on a per-protocol and an intention-to-treat analysis. Over 34 months, a total of 82 intubations were performed with 42 DL and 40 KVL based on the intention-to-treat analysis. First attempt success (28/42, 66.7% vs 25/40, 62.5%, p=0.69) and overall success (34/42, 81% vs 29/40, 72.5%, p=0.37) were similar between DL and KVL. Cormack-Lehane view and percentage of glo...
Use of the GlideScope Ranger Video Laryngoscope for Emergency Intubation in the Prehospital Setting
Critical Care Medicine, 2016
We sought to assess whether the GlideScope Ranger video laryngoscope may be a reliable alternative to direct laryngoscopy in the prehospital setting. Design: Multicenter, prospective, randomized, control trial with patient recruitment over 18 months. Setting: Four study centers operating physician-staffed rescue helicopters or ground units in Austria and Norway. Patients: Adult emergency patients requiring endotracheal intubation. Interventions: Airway management strictly following a prehospital algorithm. First and second intubation attempt employing GlideScope or direct laryngoscopy as randomized; third attempt crossover. After three failed intubation attempts, immediate use of an extraglottic airway device. Measurements and Main Results: A total of 326 patients were enrolled. Success rate with the GlideScope (n = 168) versus direct laryngoscopy (n = 158) group was 61.9% (104/168) versus 96.2% (152/158), respectively (p < 0.001). The main reasons for failed GlideScope intubation were failure to advance the tube into the larynx or trachea (26/168 vs 0/158; p < 0.001) and/or impaired sight due to blood or fluids (21/168 vs 3/158; p < 0.001). When GlideScope intubation failed, direct laryngoscopy was successful in 61 of 64 patients (95.3%), whereas Gli-deScope enabled intubation in four of six cases (66.7%) where direct laryngoscopy failed (p = 0.055). In addition, GlideScope was prone to impaired visualization of the monitor because of ambient light (29/168; 17.3%). There was no correlation between success rates and body mass index, age, indication for airway management, or experience of the physicians, respectively. Conclusions: Video laryngoscopy is an established tool in difficult airway management, but our results shed light on the specific problems in the emergency medical service setting. Prehospital use of the GlideScope was associated with some major problems, thus resulting in a lower intubation success rate when compared with direct laryngoscopy.

Purpose The first-pass success rate for endotracheal intubation (ETI) depends on provider experience and exposure. We hypothesize that video laryngoscopy (VL) improves first-pass and overall ETI success rates in low and intermediate experienced airway providers and prevents from unrecognized oesophageal intubations in prehospital settings. Methods In this study 3632 patients were included. In all cases, an ambulance nurse, HEMS nurse, or HEMS physician performed prehospital ETI using direct Laryngoscopy (DL) or VL. Results First-pass ETI success rates for ambulance nurses with DL were 45.5% (391/859) and with VL 64.8% (125/193). For HEMS nurses first-pass success rates were 57.6% (34/59) and 77.2% (125/162) respectively. For HEMS physicians these successes were 85.9% (790/920) and 86.9% (1251/1439). The overall success rate for ambulance nurses with DL was 58.4% (502/859) and 77.2% (149/193) with VL. HEMS nurses successes were 72.9% (43/59) and 87.0% (141/162), respectively. HEMS ph...

Introduction: Pre-hospital intubation is a challenging but essential intervention. During intubation, it is difficult to identify vocal cords when using a cervical collar and trauma board. Therefore, the success rate of intubation by paramedics decreases in trauma patients. Video laryngoscopy increases intubation success rate and has been recommended for difficult airways in studies. Objective: In this study, we compared the intubation success rates when using a video laryngoscope and a direct laryngoscope in a manikin with simulated cervical immobilization. Methods: In this cross-sectional study, the manikin's neck collar and spine board created a complicated airway model with cervical immobilization. Inexperienced paramedic students tried intubation with both methods, and their trial periods were recorded. Students answered a question evaluating the convenience of the procedure for both methods after the trial. Results: In this study, 83 volunteers, who were first-year and second-year paramedics, participated; 32 (38.6%) of the volunteers were first-year students, while 51 (61.4%) were second-year students. All volunteers had previous intubation experience with direct laryngoscopy, but not with video laryngoscopy. There was a statistically significant difference in the first-attempt success rates of the procedure between the groups in favor of video laryngoscope (p=0.022). Note that there was no significant difference between the groups in terms of first attempt durations (p=0.337). Conclusion: Video laryngoscopy in airway management can increase the success rate of first-attempt intubation by inexperienced pre-hospital healthcare personnel.

Objectives: Tracheal intubation in prehospital emergency care is challenging. The McGrath Mac Video Laryngoscope (Medtronic, Minneapolis, MN) has been proven to be a reliable alternative for in-hospital airway management. This trial compared the McGrath Mac Video Laryngoscope and direct laryngoscopy for the prehospital setting. Design: Multicenter, prospective, randomized, controlled equivalence trial. Setting: Oesterreichischer Automobil-und Touring Club (OEAMTC) Helicopter Emergency Medical Service in Austria, 18-month study period. Patients: Five-hundred fourteen adult emergency patients (≥ 18 yr old). Interventions: Helicopter Emergency Medical Service physicians followed the institutional algorithm, comprising a maximum of two tracheal intubation attempts with each device, followed by supraglottic, then surgical airway access in case of tracheal intubation failure. No restrictions were given for tracheal intubation indication. Measurements Main Results:: The Primary outcome was the rate of successful tracheal intubation; equivalence range was ± 6.5% of success rates. Secondary outcomes were the number of attempts to successful tracheal intubation, time to glottis passage and first endtidal Co 2 measurement, degree of glottis visualization, and number of problems. The success rate for the two devices was equivalent: direct laryngoscopy 98.5% (254/258), McGrath Mac Video Laryngoscope 98.1% (251/256) (difference, 0.4%; 99% CI,-2.58 to 3.39). There was no statistically significant difference with regard to tracheal intubation times, number of attempts or difficulty. The view to the glottis was significantly better, but the number of technical problems was increased with the McGrath Mac Video Laryngoscope. After a failed first tracheal intubation attempt, immediate switching of the device was significantly more successful than after the second attempt (90.5% vs 57.1%; p = 0.0003), regardless of the method.
