Pediatric video laryngoscope versus direct laryngoscope: a meta-analysis of randomized controlled trials

Comparison of the HugeMed video laryngoscope with the Macintosh direct laryngoscope for nasotracheal tracheal intubation in children undergoing dental treatment: a randomized controlled clinical study

OBJECTIVES

The aim of this study was to compare the performance of the HugeMed® videolaryngoscope with a direct Macintosh laryngoscope for nasotracheal intubation.

METHODS

Eighty-eight children aged 4-10 years were randomly assigned to either the HugeMed® videolaryngoscope (HVL) or the Macintosh direct laryngoscope (MDL) group. Intubation difficulty, glottic view grade, time-to-intubation, number of tracheal intubation attempts, use of external laryngeal manipulation and Magill forceps, recovery time, pediatric-anesthesia-delirium-scale (PAEDS) scores, pain due to tracheal intubation, and laryngeal bleeding were evaluated.

RESULTS

Easy tracheal intubation incidence was higher in the HVL group than that in the MDL group (p = 0.001). Glottic view was better in the HVL group as compared to the MDL group (p = 0.027). There was no difference between the groups in terms of time-to-tracheal intubation, number of tracheal intubation attempts, Magill forceps usage, pain, and bleeding due to tracheal intubation. The need for external laryngeal manipulation (p = 0.004) and PAEDS scores (p = 0.006) were higher in the MDL group than those in the HVL group.

CONCLUSION

HugeMed® videolaryngoscope may provide easier tracheal intubation, create a better glottic view, and significantly reduce the need for additional manipulation compared to the Macintosh direct laryngoscope, for nasotracheal intubation.

First-Pass Success of Intubations Using Video Versus Direct Laryngoscopy in Children With Limited Neck Mobility

OBJECTIVE

It is not clear whether video laryngoscopy (VL) is associated with a higher first-pass success rate in pediatric patients with limited neck mobility when compared with direct laryngoscopy (DL). We sought to determine the association between the laryngoscopy method and first-pass success.

METHODS

In this retrospective cohort study, we examined intubation data extracted from 2 prospectively collected, multicenter, airway management safety databases (National Emergency Airway Registry and the National Emergency Airway Registry for children), obtained during the years 2013-2018 in the emergency department. Intubations were included if patients were aged younger than 18 and had limited neck mobility. We compared first-pass success rates for ED intubations that were performed using VL versus DL. We built a structural causal model to account for potential confounders such as age, disease category (medical or trauma condition), other difficult airway characteristics, use of sedatives/paralytics, and laryngoscopist training level. We also analyzed adverse events as a secondary outcome.

RESULTS

Of 34,239 intubations (19,071 in the National Emergency Airway Registry and 15,168 in the National Emergency Airway Registry for children), a total of 341 intubations (1.0%) met inclusion criteria; 168 were performed via VL and 173 were performed via DL. The median age of patients was 124 months (interquartile range, 48-204). There was no difference in first-pass success between VL and DL (79.8% vs 75.7%, P = 0.44). Video laryngoscopy was not associated with higher first-pass success (odds ratio, 1.11; 95% confidence interval 0.84-1.47, with DL as a comparator) when a structural causal model was used to account for confounders. There was no difference in the adverse events between VL and DL groups (13.7% vs 8.7%, P = 0.19).

CONCLUSION

In children with limited neck mobility receiving tracheal intubation in the ED, neither VL nor DL was associated with a higher first-pass success rate.

A systematic review on safety and surgical and anesthetic risks of elective abdominal laparoscopic surgery in infants to guide laparoscopic ovarian tissue harvest for fertility preservation for infants facing gonadotoxic treatment

Background

Infertility is an important late effect of childhood cancer treatment. Ovarian tissue cryopreservation (OTC) is established as a safe procedure to preserve gonadal tissue in (pre)pubertal girls with cancer at high risk for infertility. However, it is unclear whether elective laparoscopic OTC can also be performed safely in infants <1 year with cancer. This systematic review aims to evaluate the reported risks in infants undergoing elective laparoscopy regarding mortality, and/or critical events (including resuscitation, circulatory, respiratory, neurotoxic, other) during and shortly after surgery.

Methods

This systematic review followed the Preferred reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting guideline. A systematic literature search in the databases Pubmed and EMbase was performed and updated on February 15th, 2023. Search terms included 'infants', 'intubation', 'laparoscopy', 'mortality', 'critical events', 'comorbidities' and their synonyms. Papers published in English since 2000 and describing at least 50 patients under the age of 1 year undergoing laparoscopic surgery were included. Articles were excluded when the majority of patients had congenital abnormalities. Quality of the studies was assessed using the QUIPS risk of bias tool.

Results

The Pubmed and Embase databases yielded a total of 12,401 unique articles, which after screening on title and abstract resulted in 471 articles to be selected for full text screening. Ten articles met the inclusion criteria for this systematic review, which included 1778 infants <1 years undergoing elective laparoscopic surgery. Mortality occurred once (death not surgery-related), resuscitation in none and critical events in 53/1778 of the procedures.

Conclusion

The results from this review illustrate that morbidity and mortality in infants without extensive comorbidities during and just after elective laparoscopic procedures seem limited, indicating that the advantages of performing elective laparoscopic OTC for infants with cancer at high risk of gonadal damage may outweigh the anesthetic and surgical risks of laparoscopic surgery in this age group.

Airway Management of Critically Ill Pediatric Patients with Suspected or Proven Coronavirus Disease 2019 Infection: An Intensivist Point of View

Advanced airway management of critically ill children is crucial for novel coronavirus disease 2019 (COVID-19) management in the pediatric intensive care unit, whether due to shock and hemodynamic collapse or acute respiratory failure. In this article, intubation is challenging due to the particularities of children's physiology and the underlying disease's pathophysiology, especially when an airborne pathogen, like COVID-19, is present. Unfortunately, published recommendations and guidelines for COVID-19 in pediatrics do not address in-depth endotracheal intubation in acutely ill children. We discussed the caveats and pitfalls of intubation in critically ill children.

Video laryngoscopy and direct laryngoscopy for cardiac arrest: A meta-analysis of clinical studies and trials

BACKGROUND

Intubation is an essential procedure in cardiopulmonary resuscitation (CPR). We conducted a systematic review and meta-analysis of trials and studies comparing the performance of video laryngoscope (VL) and direct laryngoscope (DL) in endotracheal intubation (ETI) during CPR in cardiac arrest (OHCA) patients.

METHODS

We searched the PUBMED, EMBASE, and Cochrane library databases. We analyzed the first-pass success rate, total intubation time, Cormack-Lehane grade (CL grade), esophageal intubation rate, and dental injury rate among the in-hospital cardiac arrest (IHCA) patients or out-of-hospital cardiac arrest (OHCA) patients. We demonstrated the pooled results of continuous outcomes by mean difference (MD) and dichotomous outcomes by odds ratio (OR), with a 95% confidence interval (CI) using a random-effects model.

RESULTS

We obtained six observational studies and one randomized control trial. The pooled results showed a significant increase in first-pass success rate (OR: 1.86, 95% CI: 1.41, 2.47), Cormack-Lehane (CL) grade (OR: 2.01, 95% CI: 1.59,2.53), and a decrease of esophageal intubation rate (OR: 0.25, 95% CI: 0.08, 0.85) in the VL group compared with DL group. Also, a non-significant decrease in dental injury rate [OR: 0.23, 95% CI: 0.05, 1.08) was observed in the VL group compared with the DL group. There was no statistical difference between the VL and DL groups, although the VL group seemed to have a shorter total intubation time (MD: -15.43, 95% CI: -34.67, 3.81). Types of laryngoscopes were not associated with the rate of ROSC [OR 1.01 (0.95,1.07); P = 0.83]. No differences in survival outcomes were observed between the two approaches.

CONCLUSIONS

Compared to DL, VL was found to be associated with first-pass success and CL grade. We recommend prioritizing VL over DL when performing ETIs for patients with cardiac arrest.

Neonatal airway management training using simulation-based educational methods and technology

Airway management is a fundamental component of neonatal critical care and requires a high level of skill. Neonatal endotracheal intubation (ETI), bag-mask ventilation, and supraglottic airway management are complex technical skills to acquire and continually maintain. Simulation training has emerged as a leading educational modality to accelerate the acquisition of airway management skills and train interprofessional teams. However, current simulation-based training does not always replicate neonatal airway management needed for patient care with a high level of fidelity. Educators still rely on clinical training on live patients. In this article, we will a) review the importance of simulation-based neonatal airway training for learners and clinicians, b) evaluate the available training modalities, instructional design, and challenges for airway procedural skill acquisition, especially neonatal ETI, and c) describe the human factors affecting the transfer of airway training skills into the clinical environment.

Bibliometric analysis of the top 100 most-cited articles on video laryngoscope from 2011 to 2022

BACKGROUND

The popularity of video laryngoscope (VL) has increased rapidly since its introduction in the late 1990s. However, a comprehensive overview of VLs evolution and impact is lacking, which merits further investigation.

METHODS

We conducted a bibliometric analysis of the top 100 most-cited articles on VL (Top100VL) published between 2011 and 2022 and retrieved from the PubMed and Web of Science databases. Using social network analysis, we identified the subject terms and subject categories of the Top100VL and compared their citation counts across individual subject terms and categories via one-way analysis of variance (ANOVA). Then, we employed the Medical Query Expert software to assess the practical applications of VL.

RESULTS

The Top100VL included 65 subjects across nine subject categories, with "anesthesiology" being the most frequently represented category and "coronavirus infections" with the highest impact factor. The citation counts inferred by subject categories significantly correlated with the actual citation counts (Pearson's R = 0.4; p < 0.01). For enhanced visualization, we employed network visualization and Sankey diagrams to display the article characteristics. We highlighted the clinical advantages of VL, including its usefulness in difficult intubations, wider angle of view, and management of pediatric emergencies, as well as its teaching benefits, such as facilitating training programs and a lower learning curve.

CONCLUSION

By using bibliometric analysis and natural language processing methods, we effectively summarized the applications of VL in both clinical and teaching settings, particularly in reducing the risk of cross-infection during the Coronavirus Disease 2019 pandemic.

Implementation of Video Laryngoscope-Assisted Coaching Reduces Adverse Tracheal Intubation-Associated Events in the PICU

OBJECTIVES

To evaluate implementation of a video laryngoscope (VL) as a coaching device to reduce adverse tracheal intubation associated events (TIAEs).

DESIGN

Prospective multicenter interventional quality improvement study.

SETTING

Ten PICUs in North America.

PATIENTS

Patients undergoing tracheal intubation in the PICU.

INTERVENTIONS

VLs were implemented as coaching devices with standardized coaching language between 2016 and 2020. Laryngoscopists were encouraged to perform direct laryngoscopy with video images only available in real-time for experienced supervising clinician-coaches.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was TIAEs. Secondary outcomes included severe TIAEs, severe hypoxemia (oxygen saturation < 80%), and first attempt success. Of 5,060 tracheal intubations, a VL was used in 3,580 (71%). VL use increased from baseline (29.7%) to implementation phase (89.4%; p < 0.001). VL use was associated with lower TIAEs (VL 336/3,580 [9.4%] vs standard laryngoscope [SL] 215/1,480 [14.5%]; absolute difference, 5.1%; 95% CI, 3.1-7.2%; p < 0.001). VL use was associated with lower severe TIAE rate (VL 3.9% vs SL 5.3%; p = 0.024), but not associated with a reduction in severe hypoxemia (VL 15.7% vs SL 16.4%; p = 0.58). VL use was associated with higher first attempt success (VL 71.8% vs SL 66.6%; p < 0.001). In the primary analysis after adjusting for site clustering, VL use was associated with lower adverse TIAEs (odds ratio [OR], 0.61; 95% CI, 0.46-0.81; p = 0.001). In secondary analyses, VL use was not significantly associated with severe TIAEs (OR, 0.72; 95% CI, 0.44-1.19; p = 0.20), severe hypoxemia (OR, 0.95; 95% CI, 0.73-1.25; p = 0.734), or first attempt success (OR, 1.28; 95% CI, 0.98-1.67; p = 0.073). After further controlling for patient and provider characteristics, VL use was independently associated with a lower TIAE rate (adjusted OR, 0.65; 95% CI, 0.49-0.86; p = 0.003).

CONCLUSIONS

Implementation of VL-assisted coaching achieved a high level of adherence across the PICUs. VL use was associated with reduced adverse TIAEs.

Quality Improvement of Pediatric Airway Emergency Carts: Standardization, Streamlining, and Simulation

Objective Pediatric airway emergencies are amongst the most tenuous scenarios faced by on-call providers, requiring quick access to the appropriate equipment and a timely response. In the present study, we report on the testing and improvement of pediatric airway carts at our institution. The primary objective was to optimize our pediatric airway emergency carts to improve response times. Secondarily, we aimed to implement a training scenario to improve providers' familiarity and confidence in attaining and assembling equipment. Methods Surveys of airway cart configuration at our hospital and others were used to identify differences. Volunteer otolaryngology physicians were tasked with responding to a mock scenario using an existing cart or one modified based on the survey. Outcomes included (1) time to arrival of the provider with the appropriate equipment, (2) time from arrival to complete assembly of equipment, and (3) time for re-assembly of the equipment. Results The survey revealed differences in cart equipment and location. The inclusion of a flexible bronchoscope and a video tower, as well as the placement of the carts directly within the ICU, resulted in improved time to arrival by an average of 181 seconds, and improved equipment assembly time by an average of 85 seconds. Discussion Standardization of pediatric airway equipment on the cart and location near critically ill patients improved response efficiency. Simulation led to improved confidence and reduced reaction time among providers at all levels of experience. Conclusion The present study provides an example for the optimization of airway carts, which can be adapted by healthcare systems to their local milieu.

Transitioning from Direct to Video Laryngoscopy during the COVID-19 Pandemic Was Associated with a Higher Endotracheal Intubation Success Rate

OBJECTIVE

The objective of this study was to determine the effect of transitioning from direct laryngoscopy (DL) to video laryngoscopy (VL) on endotracheal intubation success overall and with enhanced precautions implemented during the COVID-19 pandemic.

METHODS

We examined electronic transport records from Mayo Clinic Ambulance Service, a large advanced life support (ALS) provider serving rural, suburban, and urban areas in Minnesota and Wisconsin, USA. We determined the success of intubation attempts when using DL (March 10, 2018 to December 19, 2019), VL (December 20, 2019 to September 29, 2021), and VL with an enhanced COVID-19 guideline that restricted intubation to one attempt, performed by the most experienced clinician, who wore enhanced personal protective equipment (April 1 to December 18, 2020). Success rates at first attempt and after any attempt were assessed for association with type of laryngoscopy (VL vs DL) after adjusting for patient age group, patient weight, use of enhanced COVID-19 guideline, medical vs trauma patient, and ALS vs critical care clinician. A secondary analysis further adjusted for degree of glottic visualization.

RESULTS

We identified 895 intubation attempts using DL and 893 intubation attempts using VL, which included 382 VL intubation attempts using the enhanced COVID-19 guideline. Success on first intubation attempt was 69.2% for encounters with DL, 82.9% overall with VL, and 83.2% with VL and enhanced COVID-19 protocols (DL vs overall VL: p < 0.001; COVID-19 vs non-COVID VL: p = 0.86). In multivariable analysis, use of VL was associate with higher odds of successful intubation on first attempt (odds ratio, 2.28; 95%CI, 1.73-3.01; p < 0.001) and on any attempt (odds ratio, 2.16; 95%CI, 1.58-2.96; p < 0.001) compared with DL. Inclusion of glottic visualization in the model resulted in a nonsignificant association between laryngoscopy type and successful first intubation (p = 0.41) and a significant association with the degree of glottic visualization (p < 0.001).

CONCLUSIONS

VL is designed to improve glottic visualization. The use of VL by a large, U.S. multistate ALS ambulance service was associated with increased odds of successful first-pass and overall attempted intubation, which was mediated by better visualization of the glottis. COVID-19 protocols were not associated with success rates.

Management of the Difficult Airway

ABSTRACT

Airway management is a fundamental component of care during resuscitation of critically ill and injured children. In addition to predicted anatomic and physiologic differences in children compared with adults, certain conditions can predict potential difficulty during pediatric airway management. This review presents approaches to identifying pediatric patients in whom airway management is more likely to be difficult, and discusses strategies to address such challenges. These strategies include optimization of effective bag-mask ventilation, alternative approaches to laryngoscopy, use of adjunct airway devices, modifications to rapid sequence intubation, and performance of surgical airways in children. The importance of considering systems of care in preparing for potentially difficult pediatric airways is also discussed.

Efficacy and safety of video laryngoscope in indwelling gastric tube in severe coma patients: A protocol for systematic review and meta-analysis

BACKGROUND

We designed this systematic review and meta-analysis protocol to provide new medical evidence for clinical management by comparing the prognostic outcomes of visual laryngoscopy with those of conventional blinded insertion methods.

METHODS

We will intend to search English databases including Medicine, Embase, Web of Science, Cochrane Central Register of Controlled Trials, Scopus, and Google Scholar. The Chinese databases, such as Wanfang, China Knowledge Network, and China Biomedical Literature Database will also be searched. The outcome measures include intubation success rate, pain score, intubation-related complications, patient satisfaction, operation time, and cost. The Jadad scale will be used to evaluate the methodological quality of each randomized controlled trial in this meta-analysis. We will use the Methodological Index of Non-Randomized Studies criteria to assess the risk of bias in non-randomized study. An I2 value greater than 50% indicates the presence of significant heterogeneity. P < .05 in a 2-tailed test is considered statistically significant.

RESULTS

It is hypothesized that video laryngoscope will provide better outcomes compared with traditional blind gastric tube insertion.

CONCLUSIONS

The results of our review will be reported strictly following the PRISMA criteria and the review will add to the existing literature by showing compelling evidence and improved guidance in clinic settings.

Video Laryngoscopy Using King Vision™ aBlade™ and Direct Laryngoscopy in Paediatric Airway Management: A Randomized Controlled Study about Device Learning by Anaesthesia Residents

Background: Airway management in children is challenging due to anatomical and physiological differences. This randomized trial investigates whether anaesthesia residents can intubate the paediatric trachea more quickly and with a higher success rate using the King Vision™ Paediatric aBlade™ video laryngoscope (KVL) compared to conventional direct laryngoscopy (DL). Methods: Eleven anaesthesia residents (mean age: 31 years, mean training status 47 months) were each asked to perform intubations with the KVL and DL in paediatric patients. The primary outcome was the first-attempt success rate. Secondary outcomes were the time to best view (TTBV), time to placement of the tracheal tube (TTP), time to ventilation (TTV), and participant-reported ease of use on a Likert scale. Results: 105 intubations with the KVL and 106 DL were performed by the residents. The success rate on the first attempt with the KVL was 81%, and the success rate on the first attempt within a given time limit of 30 s was 45%, which was lower than with DL (93% and 77% with time limit, p < 0.01). The median TTBV [IQR] on the first attempt with KVL was 7 [5−10] s, the median TTP was 28 [19−44] s, and the median TTV was 51 [39−66] s. DL-mediated intubation was significantly faster (TTP: 17 [13−23] s; p < 0.0001 and TTV: 34 [28−44] s; p < 0.001). Application of the KVL was rated as difficult or very difficult by 60% of the residents (DL: 5%). Conclusion: In contrast to promising data on the paediatric training manikin, residents took longer to intubate the airway in children with the KVL and were less successful compared to the DL. Therefore, the KVL should not be recommended for learning paediatric intubation by residents.

Video Versus Direct Laryngoscopy in Novice Intubators: A Systematic Review and Meta-Analysis

Video laryngoscopy (VL) is increasingly used in airway management and has been shown to decrease the rate of failed intubation in certain clinical scenarios, such as difficult airways. Training novices in intubation techniques requires them to practice on living patients; however, this is less than ideal from a safety perspective given the increased risk of complications after multiple attempts or failed intubation by inexperienced trainees. One setting in which VL may be beneficial is in training, although whether these devices should be used among novices instead of direct laryngoscopy (DL) remains unclear. The purpose of this systematic review and meta-analysis is to compare the outcomes of VL and DL when used by novices to perform intubation in the operating room. The secondary aims are to correlate outcomes with different types of VLs and with different types of novices, such as medical students, residents, and non-anesthesiology trainees.

Databases were searched for studies that compared the outcomes of VL versus DL in endotracheal intubation performed by novices on patients with expected normal airways and no history of difficult intubation or cervical spine instability undergoing general anesthesia in the operating room. The primary outcome was the initial success rate. The secondary outcomes were time to intubate and the number of unintended esophageal intubations. A meta-analysis was performed to determine the difference, if any, in outcomes between VL and DL. Sub-analyses were also performed after the stratification of data by the type of VL used and the type of novice.

Ten studies were included with 1,730 intubations. Studies varied by VL type and novice type. The overall results from the meta-analysis demonstrated an increased success rate and decreased time to intubate with VL compared to DL. Four studies showed a reduction in esophageal intubation with VL compared to DL. Sub-analysis by VL type showed that improved outcomes with VL over DL were maintained only with the use of channeled VLs rather than non-channeled VLs. Sub-analysis by novice type showed that improved success rates with VL over DL were maintained only among medical students.

Novices may have a higher initial success rate and faster intubation time when using a channeled VL compared to DL. Medical students also show improved success rates when using VL rather than DL, while residents and other types of novices do not. These findings may help guide clinicians in determining the most effective devices to use when teaching airway management while also maintaining the highest possible level of patient safety.

Videolaryngoscopes versus direct laryngoscopes in children: Ranking systematic review with network meta-analyses of randomized clinical trials

BACKGROUND

Videolaryngoscopes improve tracheal intubation in adult patients, but we currently do not know whether they are similarly beneficial for children. We designed this ranking systematic review to compare individual video and direct laryngoscopes for efficacy and safety of orotracheal intubation in children.

METHODS

We searched PubMed and five other databases on January 27, 2021. We included randomized clinical trials with patients aged ≤18 years, comparing different laryngoscopes for the outcomes: failed first intubation attempt; failed intubation within two attempts; failed intubation; glottic view; time for intubation; complications. In addition, we assessed the quality of evidence according to GRADE recommendations.

RESULTS

We included 46 studies in the meta-analyses. Videolaryngoscopy reduced the risk of failed first intubation attempt (RR = 0.43; 95% CI: 0.31-0.61; p = .001) and failed intubation within two attempts (RR = 0.33; 95% CI: 0.33-0.33; p < .001) in children aged <1 year. Videolaryngoscopy also reduced the risk of major complications in both children aged <1 year (RR = 0.33; 95% CI: 0.12-0.96; p = .046) and children aged 0-18 years (RR = 0.40; 95% CI: 0.25-0.65; p = .002). We did not find significant difference between videolaryngoscopy and direct laryngoscopy for time to intubation in children aged <1 year (MD = -0.95 s; 95% CI: -5.45 to 3.57 s; p = .681), and children aged 0-18 years (MD = 1.65 s; 95% CI: -1.00 to 4.30 s; p = .222). Different videolaryngoscopes were associated with different performance metrics within this meta-analysis. The overall quality of the evidence ranged from low to very low.

CONCLUSION

Videolaryngoscopes reduce the risk of failed first intubation attempts and major complications in children compared to direct laryngoscopes. However, not all videolaryngoscopes have the same performance metrics, and more data is needed to clarify which device may be better in different clinical scenarios. Additionally, care must be taken while interpreting our results and rankings due to the available evidence's low or very low quality.

A prospective observational study of video laryngoscopy-guided coaching in the pediatric intensive care unit

BACKGROUND

There are limited data on the use of video laryngoscopy for pediatric patients outside of the operating room.

AIM

Our primary aim was to evaluate whether implementation of video laryngoscopy-guided coaching for tracheal intubation is feasible with a high level of compliance and associated with a reduction in adverse tracheal intubation-associated events.

METHODS

This is a pre-post observational study of video laryngoscopy implementation with standardized coaching language for tracheal intubation in a single-center, pediatric intensive care unit. The use of video laryngoscopy as a coaching device with standardized coaching language was implemented as a part of practice improvement. All patients in the pediatric intensive care unit were included between January 2016 and December 2017 who underwent primary tracheal intubation with either video laryngoscopy or direct laryngoscopy. The uptake of the implementation, sustained compliance, tracheal intubation outcomes including all adverse tracheal intubation-associated events, oxygen desaturations (<80% SpO2), and first attempt success were measured.

RESULTS

Among 580 tracheal intubations, 284 (49%) were performed during the preimplementation phase, and 296 (51%) postimplementation. Compliance for the use of video laryngoscopy with standardized coaching language was high (74% postimplementation) and sustained. There were no statistically significant differences in adverse tracheal intubation-associated events between the two phases (pre- 9% vs. post- 5%, absolute difference -3%, CI95 : -8% to 1%, p = .11), oxygen desaturations <80% (pre- 13% vs. post- 13%, absolute difference 1%, CI95 : -6% to 5%, p = .75), or first attempt success (pre- 73% vs. post- 76%, absolute difference 4%, CI95 : -3% to 11%, p = .29). Supervisors were more likely to use the standardized coaching language when video laryngoscopy was used for tracheal intubation than with standard direct laryngoscopy (80% vs. 43%, absolute difference 37%, CI95 : 23% to 51%, p < .001).

CONCLUSIONS

Implementation of video laryngoscopy as a supervising device with standardized coaching language was feasible with high level of adherence, yet not associated with an increased occurrence of any adverse tracheal intubation-associated events and oxygen desaturation.

Effectiveness of Indirect and Direct Laryngoscopes in Pediatric Patients: A Systematic Review and Network Meta-Analysis

This research aimed to produce a coherent ranking of the effectiveness of intubation devices in pediatric patients using network meta-analysis (NMA). We searched the electric databases for prospective randomized studies that compared different tracheal intubation devices in pediatric patients. The primary outcome was intubation failure at the first attempt. Secondary outcomes were glottic visualization and intubation time. The statistical analysis performed used DerSimonian and Laird random-effects models. Frequentist network meta-analysis was conducted, and network plots and network league tables were produced. Subgroup analysis was performed after excluding rigid-fiberscope-type indirect laryngoscopes. Thirty-four trials comparing 13 devices were included. Most laryngoscopes had the same intubation failure rate as the Macintosh reference device. Only the Truview PCD™ had a significantly higher intubation failure rate than the Macintosh (odds ratio 4.78, 95% confidence interval 1.11–20.6) The highest-ranking laryngoscope was the Airtaq™ (P score, 0.90), and the AirwayScope™, McGrath™, and Truview EVO2™ ranked higher than the Macintosh. The Bullard™ had the lowest ranking (P score, 0.08). All laryngoscopes had the same level of glottic visualization as the Macintosh and only the C-MAC™ had a significantly shorter intubation time. Intubation time was significantly longer when using the GlideScope™, Storz DCI™, Truview PCD™, or Bullard™ compared with the Macintosh. P score and ranking of devices in the subgroup analyses were similar to those in the main analysis. We applied NMA to create a consistent ranking of the effectiveness of intubation devices in pediatric patients. The findings of NMA suggest that there is presently no laryngoscope superior to the Macintosh laryngoscope in terms of tracheal intubation failure rate and glottic visualization in pediatric patients.

Comparison of the UEscope Video Laryngoscope with the Traditional Direct Laryngoscope in Neonates and Infants: A Randomized Clinical Trial

The role of video laryngoscopy in adults is well established, but its role in children is still inconclusive. Previous studies on the UEscope in pediatric patients with difficult airways showed that it could reduce the time to intubation (TTI) compared to a conventional direct laryngoscope. The main objective of the current study was to investigate if the use of the UEscope could reduce the TTI in neonates and infants. Forty patients under 12 months old were recruited from a single tertiary hospital from March 2020 to September 2021 and were randomly assigned to the direct laryngoscope group (n = 19, neonates = 4, infants = 15) or UEscope group (n = 21, neonates = 6, infants = 15). Although the quality of glottic view was comparable in both groups, the TTI was significantly lower in the UEscope group in both the “intention-to-treat” (–19.34 s, 95% confidence interval = –28.82 to –1.75, p = 0.0144) and “as treated” (–11.24 s, 95% confidence interval: –21.73 to 0, p = 0.0488) analyses. The UEscope may be a better choice for tracheal intubation than conventional direct laryngoscope in neonates and infants.

Facilitators and Barriers to Implementing Two Quality Improvement Interventions Across 10 Pediatric Intensive Care Units: Video Laryngoscopy-Assisted Coaching and Apneic Oxygenation

To better understand facilitators and barriers to implementation of quality improvement (QI) efforts, this study examined 2 evidence-based interventions, video laryngoscopy (VL)-assisted coaching, and apneic oxygenation (AO). One focus group with frontline clinicians was held at each of the 10 participating pediatric intensive care units. Qualitative analysis identified common and unique themes. Intervention fidelity was monitored with a priori defined success as >50% VL-assisted coaching or >80% AO use for 3 consecutive months. Eighty percent of intensive care units with VL-assisted coaching and 20% with AO met this criteria during the study period. Common facilitator themes were adequate device accessibility, having a QI culture, and strong leadership. Common barrier themes included poor device accessibility and perception of delay in care. A consistently identified theme in the successful sites was strong QI leadership, while unsuccessful sites consistently identified insufficient education. These facilitators and barriers should be proactively addressed during dissemination of these interventions.

Challenge of Lung Isolation in Patients with Vocal Cord Implants

Glottic closure insufficiency increases the risk of aspiration and pneumonia, particularly in the elderly. Medialization thyroplasty is an open surgical procedure for treating glottic incompetency by approximating both vocal folds. The vocal fold medialization is achieved by inserting an implant to bring the nonmobile fold to the unaffected side. Lung isolation in patients with vocal cord implantation poses a unique challenge. Understanding the risks of different modalities of lung isolation and their impacts on the vocal cord implant is crucial to implementing a specifically tailored plan. Preoperative bronchoscopy, intraoperative video laryngoscopy, and bronchoscopy are ideal methods for assessing the vocal fold implants and guiding the lung isolation technique. Bronchial blocker through a single-lumen endotracheal tube may be the preferred choice to avoid the injury of the stretched vocal cords and dislodgement of the implant by a larger diameter double-lumen tube.

Prehospital Pediatric Respiratory Distress and Airway Management Interventions: An NAEMSP Position Statement and Resource Document

Devices and techniques such as bag-valve-mask ventilation, endotracheal intubation, supraglottic airway devices, and noninvasive ventilation offer important tools for airway management in critically ill EMS patients. Over the past decade the tools, technology, and strategies used to assess and manage pediatric respiratory and airway emergencies have evolved, and evidence regarding their use continues to grow.NAEMSP recommends:Methods and tools used to properly size pediatric equipment for ages ranging from newborns to adolescents should be available to all EMS clinicians. All pediatric equipment should be routinely checked and clearly identifiable in EMS equipment supply bags and vehicles.EMS agencies should train and equip their clinicians with age-appropriate pulse oximetry and capnography equipment to aid in the assessment and management of pediatric respiratory distress and airway emergencies.EMS agencies should emphasize noninvasive positive pressure ventilation and effective bag-valve-mask ventilation strategies in children.Supraglottic airways can be used as primary or secondary airway management interventions for pediatric respiratory failure and cardiac arrest in the EMS setting.Pediatric endotracheal intubation has unclear benefit in the EMS setting. Advanced approaches to pediatric ETI including drug-assisted airway management, apneic oxygenation, and use of direct and video laryngoscopy require further research to more clearly define their risks and benefits prior to widespread implementation.If considering the use of pediatric endotracheal intubation, the EMS medical director must ensure the program provides pediatric-specific initial training and ongoing competency and quality management activities to ensure that EMS clinicians attain and maintain mastery of the intervention.Paramedic use of direct laryngoscopy paired with Magill forceps to facilitate foreign body removal in the pediatric patient should be maintained even when pediatric endotracheal intubation is not approved as a local clinical intervention.

Success rate and duration of orotracheal intubation of premature infants by healthcare providers with different levels of experience using a video laryngoscope as compared to direct laryngoscopy in a simulation-based setting

BACKGROUND

Endotracheal intubation of very low birth weight infants (VLBWI) is an essential procedure in NICUs, but intubation experience is often limited. Video laryngoscopy (VL) has been described as a tool to improve intubation skills, but studies in high-risk neonatal populations are limited.

OBJECTIVE

The aim of this study was to investigate whether VL is a useful tool to support airway management in high-risk premature infants with inexperienced operators.

METHODS

In this crossover study predominantly inexperienced participants were exposed in random sequence to VL and conventional direct laryngoscopy (DL) for endotracheal intubation of a VLBWI simulation manikin to measure total time, number of attempts, success rate on first attempt, view of the vocal cords and perceived subjective safety until successful intubation.

RESULTS

In our study group of 94 participants there was no significant difference in the total time (mean VL: 34 s (±24 s); DL: 37 s (±28 s), p = 0.246), while the number of intubation attempts using VL was significantly lower (mean VL: 1.22 (±0.53); DL: 1.37 (±0.60), p = 0.023). Success rate of VL during the first attempt was significantly higher (VL: 84%; DL 69%, p = 0.016), view of the vocal cords was significantly better and perceived subjective safety was increased using VL.

CONCLUSIONS

Our study results suggest that with rather inexperienced operators, VL can be a useful tool to increase rate of successful endotracheal intubation of VLBWI and to improve their perceived safety during the procedure, which may have an impact on mortality and/or morbidity.

A randomized comparative evaluation of C-MAC video-laryngoscope with Miller laryngoscope for neonatal endotracheal intubation

Background and Aims

An efficient neonatal airway management is peculiarly challenging even in the most experienced hands. Considering the recent interest in assessing the performance of various video-laryngoscopes (VL) in pediatric cohort, the prospective randomized study was contemplated to stage a comparative evaluation of C-MAC with Miller laryngoscope for neonatal endotracheal intubation.

Material and Methods

150 neonates were randomized to undergo intubation with either the C-MAC VL (n = 75) or the Miller laryngoscope (n = 75) performed by an experienced anesthesiologist in a tertiary care perioperative setting. The percentage of glottic opening (POGO), time to best glottic view (TTBGV), time to intubation (TTI), number of attempts, optimal external laryngeal manipulation (OELM) employed, and the complications were assessed and compared between the two groups.

Results

C-MAC group demonstrated a significantly higher POGO, compared to the Miller group (88 ± 26.7%;76.8 ± 32.1%, respectively, P = 0.022). TTBGV was significantly lower in the C-MAC (7.7 ± 0.1s) group as opposed to the Miller group (11.3 ± 1.1s). The C-MAC group displayed higher TTI values compared to the Miller group (25.4 ± 1.6s; 19.7 ± 1.2s, respectively, P < 0.01). The first-attempt intubation success rate and the number of attempts were comparable in both the groups. OELM was required in 24% of the patients in the Miller group as opposed to 10.7% in the C-MAC group (P = 0.031). Higher patient percentage in the C-MAC group required the need of stylet for assisting a successful intubation, although the difference between the two groups was not statistically significant.

Conclusion

Despite an improved view of the glottis, the TTI was higher for C-MAC compared to direct laryngoscopy with a comparable first-attempt success rate in the two techniques.

Video Laryngoscope Screen Visualization and Tracheal Intubation Performance: A Video-Based Study in a Pediatric Emergency Department

STUDY OBJECTIVE

Our study objectives were to describe patterns of video laryngoscope screen visualization during tracheal intubation in a pediatric emergency department (ED) and to determine their associations with procedural performance.

METHODS

We conducted a prospective, observational, video-based study of pediatric ED patients undergoing tracheal intubation with a standard geometry video laryngoscope (Storz C-MAC; Karl Storz, Tuttlingen, Germany). Our primary exposure was video screen visualization patterns, measured by the percentage of each attempt spent viewing the screen and the number of times the proceduralist changed their gaze between the patient and screen (gaze switches). Our primary outcome was first-pass success. We compared measures of screen visualization between successful and unsuccessful first attempts using a generalized linear mixed model.

RESULTS

From December 2019 to October 2021, we collected data on 153 patients. The first-pass success rate was 79.1%. Proceduralists viewed the video screen during 80.4% of attempts; the median percentage of each attempt spent viewing the video screen was 42.1% (interquartile range 8.7% to 65.5%). The median number of gaze switches per attempt was 3 (interquartile range 1 to 6, maximum 22). The percentage of each attempt spent viewing the video screen was not associated with success (adjusted odds ratio 1.00, 95% confidence interval 0.93 to 1.08); additional gaze switches were associated with a lower likelihood of success (adjusted odds ratio 0.80, 95% confidence interval 0.71 to 0.90).

CONCLUSION

We found wide variation in how proceduralists viewed the video laryngoscope screen during intubations in a pediatric ED. We illustrate the application of 2 objective screen visualization measures to quantify and understand how clinicians actually use video laryngoscopy.

Comparison of McGrath Videolaryngoscope and Macintosh Laryngoscope in Children with Torticollis: Randomized Controlled Trial

We investigated the efficacy of the McGrath videolaryngoscope compared with the Macintosh laryngoscope in children with torticollis. Thirty children aged 1–10 years who underwent surgical release of torticollis were randomly assigned into the McGrath and Macintosh groups. Orotracheal intubation was performed by a skilled anesthesiologist. The primary outcome was the intubation time. The Cormack–Lehane grade, lifting force, intubation difficulty scale (IDS), difficulty level, and intubation failure rate were also assessed. The intubation time was significantly longer in the McGrath group than in the Macintosh group (31.4 ± 6.7 s vs. 26.1 ± 5.4 s, p = 0.025). Additionally, the Cormack–Lehane grades were comparable between the groups (p = 0.101). The lifting force and IDS were significantly lower in the McGrath group than in the Macintosh group (p < 0.001 and p = 0.022, respectively). No significant differences were observed with respect to endotracheal intubation difficulty and intubation success rate. Intubation-related complications were also not observed. In conclusion, compared with the Macintosh laryngoscope, the McGrath videolaryngoscope extended the intubation time and did not improve glottic visualization in children with torticollis, despite having a lesser lifting force, lower intubation difficulty scale, and similar success rate.

Association between the number of endotracheal intubation attempts and rates of adverse events in a paediatric emergency department

BACKGROUND

Challenges in emergent airway management in children can affect intubation success. It is unknown if number of endotracheal intubation attempts is associated with rates of adverse events in the paediatric ED setting.

OBJECTIVE

We sought to (1) Identify rates of intubation-related adverse events, (2) Evaluate the association between the number of intubation attempts and adverse events in a paediatric ED, and (3) Determine the effect of videolaryngoscopy on these associations.

DESIGN AND METHODS

We performed a retrospective observational study of patients who underwent endotracheal intubation in a paediatric ED in the USA between January 2004 and December 2018. Data on patient-related, provider-related and procedure-related characteristics were obtained from a quality assurance database and the health record. Our primary outcome was frequency of intubation-related adverse events, categorised as major and minor. The number of intubation attempts was trichotomised to 1, 2, and 3 or greater. Multivariable logistic regression models were used to determine the relationship between the number of intubation attempts and odds of adverse events, adjusting for demographic and clinical factors.

RESULTS

During the study period, 628 patients were intubated in the ED. The overall rate of adverse events was 39%. Hypoxia (19%) was the most common major event and mainstem intubation (15%) the most common minor event. 72% patients were successfully intubated on the first attempt. With two intubation attempts, the adjusted odds of any adverse event were 3.26 (95% CI 2.11 to 5.03) and with ≥3 attempts the odds were 4.59 (95% CI 2.23 to 9.46). Odds similarly increased in analyses of both major and minor adverse events. This association was consistent for both traditional and videolaryngoscopy.

CONCLUSION

Increasing number of endotracheal intubation attempts was associated with higher odds of adverse events. Efforts to optimise first attempt success in children undergoing intubation may mitigate this risk and improve clinical outcomes.

Clinical Experience With the C-MAC and GlideScope in a Pediatric Emergency Department Over a 10-Year Period

OBJECTIVE

There is little literature describing the performance of video laryngoscopes for the intubation of pediatric patients in the emergency department (ED). The purpose of this study is to report our experience with direct laryngoscopy (DL), the C-MAC (CMAC), and the GlideScope (GVL) over a 10-year period in an urban academic pediatric ED.

METHODS

This was an analysis of pediatric intubations prospectively recorded into a Continuous Quality Improvement database in an academic pediatric ED over a 10-year period. Between July 1, 2007, and June 30, 2017, emergency physicians recorded all consecutive intubations performed in the pediatric ED. The database included patient demographics and detailed information on each intubation such as age of the patient, reason for intubation, device(s) used, method of intubation, difficult airway characteristics, adverse events, number of intubation attempts, and outcome of each attempt. All patients younger than 18 years who underwent intubation by an emergency medicine resident using a DL or videolaryngoscope (CMAC or GVL) were included in the study. The primary outcome measure was first-pass success without adverse events (FPS-AE), which was defined as successful tracheal intubation on a single laryngoscope insertion without the occurrence of any adverse events during the peri-intubation period. A multivariate regression analysis was performed to control for potential confounders and included difficult airway characteristic, operator level of training, method of intubation, and patient age.

RESULTS

During the study period, 530 intubations were performed in pediatric patients. Of these, 493 intubations met the inclusion criteria and were analyzed (218 DL, 187 CMAC, 88 GVL). The FPS-AE with each device is as follows: DL, 54.1% (n = 118/218); CMAC, 64.0% (n = 119/187); and GVL, 52.3% (n = 46/88). In the logistic regression analysis, compared with DL, the CMAC was associated with a higher FPS-AE (odds ratio, 1.6 [95% confidence interval, 1.03-2.45]), whereas the GVL was not associated with an increased FPS-AE (odds ratio, 0.62 [95% confidence interval, 0.35-1.10]).

CONCLUSIONS

In this study of pediatric patients intubated in the ED, compared with DL, the CMAC was associated with an increased FPS-AE, but the GVL was not.

Efficacy and Safety of Video-Laryngoscopy versus Direct Laryngoscopy for Double-Lumen Endotracheal Intubation: A Systematic Review and Meta-Analysis

The available meta-analyses have inconclusively indicated the advantages of video-laryngoscopy (VL) in different clinical situations; therefore, we conducted a systematic review and meta-analysis to determine efficacy outcomes such as successful first attempt or time to perform endotracheal intubation as well as adverse events of VL vs. direct laryngoscopes (DL) for double-lumen intubation. First intubation attempt success rate was 87.9% for VL and 84.5% for DL (OR = 1.64; 95% CI: 0.95 to 2.86; I² = 61%; p = 0.08). Overall success rate was 99.8% for VL and 98.8% for DL, respectively (OR = 3.89; 95%CI: 0.95 to 15.93; I² = 0; p = 0.06). Intubation time for VL was 43.4 ± 30.4 s compared to 54.0 ± 56.3 s for DL (MD = −11.87; 95%CI: −17.06 to −6.68; I² = 99%; p < 0.001). Glottic view based on Cormack–Lehane grades 1 or 2 equaled 93.1% and 88.1% in the VL and DL groups, respectively (OR = 3.33; 95% CI: 1.18 to 9.41; I² = 63%; p = 0.02). External laryngeal manipulation was needed in 18.4% cases of VL compared with 42.8% for DL (OR = 0.28; 95% CI: 0.20 to 0.40; I² = 69%; p < 0.001). For double-lumen intubation, VL offers shorter intubation time, better glottic view based on Cormack–Lehane grade, and a lower need for ELM, but comparable first intubation attempt success rate and overall intubation success rate compared with DL.

Comparison of direct laryngoscopy and video-assisted laryngoscopy in pediatric intensive care unit

Our objective was to compare video-assisted laryngoscopy (VAL) with direct laryngoscopy (DL) for glottic visualization in a pediatric intensive care unit in terms of the success rate in first attempts. Our study included patients aged from 1 month to 18 years who were admitted to the pediatric intensive care unit. We excluded patients with limited neck extension (C-spine immobilization, congenital abnormality), congenital anomalies (e.g., Pierre Robin syndrome, micrognathia, macroglossia), and recent airway surgery. Patients were premedicated before intubation. The time to intubation was defined as the time between the start of anesthesia and completion of intubation. The start of anesthetic induction was defined as the time the sedative was first administered. Completion of intubation was defined as the time that the end-tidal carbon dioxide tension was detected. We evaluated 120 of 135 intubations that met our inclusion criteria; 15 were excluded because in eight cases (53%) non-pediatric intensive care physicians made the initial attempts, and in seven cases (47%) the recorded intubation times were erroneous. We detected significantly higher POGO scores in the VAL group (p<0.001). VAL provided a fuller view of the glottis (Cormack and Lehane grade 1) than DL (p<0.001). Although the intubation attempts in the DL group were significantly higher (two or more attempts), no intubation failures occurred in either group.

Comparative efficacy of C-MAC® Miller videolaryngoscope versus McGrath® MAC size "1" videolaryngoscope in neonates and infants undergoing surgical procedures under general anesthesia: A prospective randomized controlled trial

BACKGROUND

Various anatomical and physiological factors make intubation in infants challenging. C-MAC videolaryngoscope shows better results as compared to the conventional direct laryngoscopy for intubation in infants. McGrath MAC size-1 with a disposable Macintosh type blade has recently been introduced for use in infants and has not been formally evaluated in this population.

AIMS

This study aims to evaluate the intubation characteristics of C-MAC Miller and McGrath MAC in neonates and infants with the primary objective to compare the time with the two devices.

METHODS

After informed consent from the parents, 140 neonates and infants scheduled for surgical procedures were randomized to undergo intubation with either C-MAC Miller or McGrath MAC after standard general anesthesia. The two devices were compared in terms of total intubation time, Percent of Glottic Opening score, Cormack Lehane grades, time to glottis view, intubation difficulty score, overall success rate, first attempt success rate, and complications.

RESULTS

The median glottic view time (6 s [4-9] vs. 6 s [4-9]; p = .40) and intubation time (27 s [25.5-28] vs. 27 s [24.5-29.5]; p = .87) were similar. The mean difference (95% CI) in time to tracheal intubation and time to glottic view was 0.49 s [-3.1 to 2.1] and -1.7 s [-3.8 to 0.47], respectively. However, the Percent of Glottic Opening score, Cormack Lehane grades, and subjective intubation difficulty were significantly better with C-MAC. The first attempt success rates, overall success rates (100% vs. 97.5%), and intubation difficulty scores were comparable. There were two failed intubations with McGrath which were successfully intubated with C-MAC.

CONCLUSION

The C-MAC Miller blade showed similar intubation timings, success rates, and intubation difficulty score as compared to McGrath MAC in neonates and infants, though the former provided superior glottic views. Both the videolaryngoscopes may be safely used in infants and neonates for routine intubation scenarios.

Use of the C-MAC Macintosh 0 Blade for Intubation of Infants in the Emergency Department

ABSTRACT

First-pass success rates during intubation of infants in the emergency department have been shown to be low. Video laryngoscopy is being increasingly used during advanced airway management in the emergency department, but available data have not supported improved outcomes with use in pediatrics. The newly available Macintosh size 0 (curved) blade for the C-MAC video laryngoscope offers a narrower blade for use in infants. We describe the use of the new C-MAC Macintosh 0 blade for intubation of 2 infants with apnea secondary to respiratory syncytial virus bronchiolitis. The included video recording demonstrates the favorable glottic view and improved maneuverability offered by the narrower blade but also highlights the limitation in use beyond young infants given the short blade length.

A systematic review of meta-analyses comparing direct laryngoscopy with videolaryngoscopy

PURPOSE

In the preceding 20 years, many randomized-controlled trials and meta-analyses have compared direct Macintosh laryngoscopy with videolaryngoscopy. The videolaryngoscope blades have included both traditional Macintosh blades and hyperangulated blades. Macintosh and hyperangulated blades differ in their geometry and technique for tracheal intubation; certain patient populations may benefit from one blade type over another. The primary objective of this systematic review was to assess whether published meta-analyses comparing direct Macintosh laryngoscopy to videolaryngoscopy have accounted for the videolaryngoscope blade type. Secondary objectives evaluated heterogeneity among practitioner experience and specialty, clinical context, patient population, and original primary study outcomes.

SOURCE

A search was performed across Ovid Medline, Ovid Embase, ClinicalKey, PubMed, TRIP, AccessAnesthesiology, Google Scholar, and ANZCA discovery. A systematic review identified meta-analyses which compared direct Macintosh laryngoscopy to videolaryngoscopy. There were no patient age or clinical specialty restrictions. Exclusion criteria included non-English language, studies comparing non-Macintosh blade to videolaryngoscopy, and studies in awake patients.

PRINCIPAL FINDINGS

Twenty-one meta-analyses were identified that were published between 1 January 2000 and 7 May 2020. Macintosh and hyperangulated videolaryngoscope blades were combined in most studies (16/21; 76%). Heterogeneity was also present among practitioner experience (20/21; 95%), clinician specialty (15/21; 71%), and clinical locations (10/21; 48%). Adult and pediatric patients were combined or not defined in 5/21 studies (24%). The primary outcomes of the meta-analyses varied, with the most common (7/21; 33%) being first-pass tracheal intubation success.

CONCLUSIONS

Heterogeneity across important clinical variables is common in meta-analyses comparing direct Macintosh laryngoscopy to videolaryngoscopy. To better inform patient care, future videolaryngoscopy research should differentiate blade type, clinical context, and patient-related primary outcomes.

Conceptualizing intubation sharing: A descriptive qualitative study of videolaryngoscopy for pediatric emergency airway management

BACKGROUND

This study characterizes clinical and educational practices around the use of videolaryngoscopy in pediatric emergency airway management through qualitative exploration.

METHODS

This is a descriptive qualitative study using semi-structured interviews of emergency medicine physicians. Physicians were selected by theoretical sampling from urban, tertiary care pediatric hospitals across the United States until theoretical data saturation was achieved. The study applied a constructivist grounded theory approach to data collection and analysis. Manual line-by-line coding of interview transcripts was used initially, then grouped into categories with constant comparative analysis to generate the final coding scheme organized by themes and subthemes. Finally, memo-writing and iterative analysis meetings explored relationships between themes and identified an interpretive model.

RESULTS

Theoretical saturation was achieved after 10 of the initial 12 interviews. Emerging from the data were six themes that describe the concept of intubation sharing: (1) Videolaryngoscopy encompasses multiple modalities that all provide a shared view and ability to record; (2) Airway experts and systems help realize the full potential of videolaryngoscopy; (3) Videolaryngoscopy can be a clinical, educational, quality assurance and research tool; (4) Some skills required for videolaryngoscopy are unique, while others overlap with direct laryngoscopy; (5) Videolaryngoscopy allows a coaching laryngoscopist to provide real-time guidance to the primary laryngoscopist from a shared view; (6) Videolaryngoscopy provides an opportunity for post-intubation coaching and feedback and shared learning from a single experience for the provider community.

CONCLUSIONS

Through this multicenter qualitative interview study, we derived the concept of intubation sharing through videolaryngoscopy for real-time and remote coaching, for both the primary laryngoscopist and the community of emergency medicine providers who intubate.

Evolution of videolaryngoscopy in pediatric population

Direct laryngoscopy has remained the sole method for securing airway ever since the inception of endotracheal intubation. The recent introduction of video-laryngoscopes has brought a paradigm shift in the pratice of airway management. It is claimed that they improve the glottic view and first pass success rates in adult population. The airway management in children is more challenging than adults. The role of videolaryngoscopy for routine intubation in children is not clearly proven. This review attempts to discuss various videolaryngosocpes available for use in pediatric patients.

Technical factors associated with first-pass success during endotracheal intubation in children: analysis of videolaryngoscopy recordings

BACKGROUND

First-pass success (FPS) during intubation is associated with lower morbidity for paediatric patients. Using videolaryngoscopy (VL) recordings, we reviewed technical aspects of intubation, including factors associated with FPS in children.

METHODS

We performed a retrospective study of intubation attempts performed using video-assisted laryngoscopy in a paediatric ED between January 2014 and December 2018. Data were abstracted from a quality assurance database, the electronic medical record and VL recordings. Our primary outcome was FPS. Intubation practices were analysed using descriptive statistics. Patient and procedural characteristics associated with FPS in univariate testing and clinical factors identified from the literature were included as covariates in a multivariable logistic regression. An exploratory analysis examined the relationship between position of the glottic opening on the video screen and FPS.

RESULTS

Intubation was performed during 237 patient encounters, with 231 using video-assisted laryngoscopy. Data from complete video recordings were available for 129 attempts (59%); an additional 31 (13%) had partial recordings. Overall, 173 (73%) of first attempts were successful. Adjusting for patient age, placing the blade tip into the vallecula adjusted OR ((aOR) 7.2 (95% CI 1.7 to 30.1)) and obtaining a grade 1 or 2a-modified Cormack-Lehane glottic view on the videolaryngoscope screen (aOR 6.1 (95% CI 1.5 to 25.7) relative to grade 2b) were associated with increased FPS in the subset of patients with complete recordings. Exploratory analysis suggested that FPS is highest (81%) and duration is shortest when the glottic opening is located in the second quintile of the video screen.

CONCLUSIONS

Placement of the blade tip into the vallecula regardless of blade type, sufficient glottic visualisation and locating the glottic opening within the second quintile of the video screen were associated with FPS using video-assisted laryngoscopy in the paediatric ED.

Comparison of paediatric King Vision™ videolaryngoscope and Macintosh laryngoscope for elective tracheal intubation in children of age less than 1 year: A randomised clinical trial

Background and Aims

Paediatric airway, because of its consistent anatomical differences from that of an adult, often encounters difficulty in aligning the line of sight with the laryngeal inlet during intubation. Paediatric videolaryngoscopes (VLs), by obviating the need for aligning the line of sight with the glottis, offer several advantages over direct laryngoscopy. Therefore, this study aimed to compare the recently introduced paediatric King Vision™ VL (KVL) and the direct laryngoscope with Macintosh blade for elective tracheal intubation in infants of age <1 year.

Methods

Seventy-eight infants of American Society of Anesthesiologists physical status 1 and 2, scheduled for elective surgery, were enrolled for this prospective randomised clinical trial and randomised into either of the two groups - Group K and Group C, where the infants were intubated using size 1 King Vision or direct laryngoscope with Macintosh blade. The primary objective of this study was the time taken for intubation and the first-attempt intubation success rate.

Results

Time to intubate (25.90 ± 2.34 s vs. 25.03 ± 1.42 s, P = 0.05) and first-attempt intubation success rate (100% vs. 100%, P = 1) were similar between the groups, whereas glottic visualisation (P = 0.01), alternate techniques used to assist intubation (P < 0.001), the ease of intubation (P = 0.02) and intubation difficulty score (P = 0.01) were better in Group K than that in Group C.

Conclusion

The outcome of KVL and Macintosh laryngoscope was similar in terms of time taken for intubation and first-attempt intubation success rate with KVL having superior glottic visualisation, better ease of intubation and lower intubation difficulty score for elective intubations in children of age <1 year.

Direct laryngoscopy assisted fiberoptic intubation: A novel technique for the pediatric airway

OBJECTIVE

To introduce a novel intubation technique for difficult pediatric airways.

METHODS

This two-provider technique requires a direct laryngoscope and a flexible fiberoptic laryngoscope. One provider performs direct laryngoscopy which allows for introduction of the flexible laryngoscope. The second provider inserts the flexible laryngoscope with the endotracheal tube loaded, through the oropharynx in to the subglottis.

RESULTS

We report three pediatric patients that were initially unable to be intubated by conventional methods. We were ultimately able to successfully intubate these patients with difficult airways using our novel technique.

CONCLUSIONS

We found that this technique of direct laryngoscopy assisted flexible fiberoptic intubation is a useful adjunct in select pediatric difficult airway patients.

Intubation practices for children in emergency departments and intensive care units across Australia and New Zealand: A survey of medical staff

OBJECTIVE

Intubation of children in the emergency setting is a high-risk, low incidence event. Standardisation of clinical practice has been hampered by a lack of high-quality evidence to support one technique over another. The aim of the present study is to determine clinician preference in intubation practice of children in EDs and ICUs in Australia and New Zealand to provide baseline information to allow future targeted research focused on improving the safety and efficacy of paediatric emergency airway management.

METHODS

The present study was a voluntary questionnaire undertaken by medical staff at registrar level or above in EDs and ICUs associated with the Paediatric Research in Emergency Departments International Collaborative (PREDICT) and Australia and New Zealand Intensive Care Society Paediatric Study Group (ANZICS PSG) research networks. Respondents reported on their individual intubation practices, with a focus on pre-oxygenation and apnoeic oxygenation techniques, and the use of video laryngoscopy.

RESULTS

A total of 502 clinicians were invited to complete the survey between May and October 2018 with 336 (66.9%) responded. There was marked variation in practice between ED clinicians and ICU clinicians in the techniques used for pre-oxygenation, the frequency of use of apnoeic oxygenation and the reported use of video laryngoscopy.

CONCLUSIONS

Within Australia and New Zealand there is considerable variation in paediatric emergency airway clinical practice, in particular with respect to pre-oxygenation, apnoeic oxygenation and use of video laryngoscopy. Definitive clinical trials are required to best inform clinical practice in this area.

The Comparison of Direct Laryngoscopy and Video Laryngoscopy in Pediatric Airways Management for Congenital Heart Surgery: A Randomized Clinical Trial

Background

Airway management in patients with hereditary heart disease is an important therapeutic intervention.

Objectives

The purpose of this study was to compare direct laryngoscopy (DL) with video laryngoscopy (VL) in pediatric airways management for congenital heart surgery.

Methods

This study was designed as a prospective randomized clinical trial. Two consecutive groups of 30 patients undergoing elective noncyanotic congenital heart surgery. The patients were divided into direct laryngoscopy versus video laryngoscopy for intubation of the trachea. The main outcomes were the number of success rate in the first attempt, and the secondary outcomes were the duration of successful intubation and complications, such as desaturation and bradycardia.

Results

Intubation procedure time was measured as 51.13 ± 17.88 seconds for the group with direct laryngoscopy and 59.66 ± 45.91 seconds for group with VL that was significant (P = 0.006). In DL group, 22 patients were intubated on the first attempt, 8 patients on the second attempt, and 6 patients on the third attempt, compared to 24, 6, and 2 respectively, in VL group. The differences were significant only in the third attempt between groups (P = 0.033). The important difference established in heart rate (HR) and SpaO₂ amounts between the two groups at any time (P < 0.05).

Conclusions

VL can produce better visualization for intubation of trachea in congenital heart disease, but this is time-consuming. Indeed, training in the use of the VL should be increased to reduce the time required for performance. Moreover, further studies are recommended to approve these helpful findings.

Novel airway device Vie Scope in several pediatric airway scenario: A randomized simulation pilot trial

CONTEXT

Endotracheal intubation of pediatric patients is challenging, especially in the pre-hospital emergency setting and if performed by less experienced providers. Securing an airway should be achieved with a single intubation attempt, as each intubation attempt contributes to morbidity and mortality. A new airway device, the VieScope, was recently introduced into clinical market, but efficacy to reduced intubation attempts remains unclear thus far.

OBJECTIVE

We aimed to compare endotracheal intubation by paramedics using the Vie Scope in different pediatric airway simulation conditions.

METHODS

We conducted a randomized, cross-over simulation study. Following a theoretical and practical training session, paramedics performed endotracheal intubation in 3 different pediatric emergency scenarios: normal airway; tongue edema; cardiopulmonary resuscitation using the VieScope. Overall intubation success rate was the primary outcome. Secondary outcomes included number of intubation attempts, time to intubation, Cormack-Lehane grade, POGO score, and ease of use (using 1-100 scale).

RESULTS

Fifty-five paramedics with at least 2 years of clinical experience and without any previous experience with the VieScope participated in this study. The overall intubation success rate was 100% in all 3 scenarios. The median intubation time was 27 (24-34) versus 27 (25-37) versus 29 (25-40) s for scenarios A, B, and C, respectively. In scenario A, all paramedics performed successful intubation with 1 single intubation attempt, whereas 2% of the paramedics had to perform 2 intubation attempts in scenario B and 9% in scenario C.

CONCLUSIONS

Results of this simulation study indicate preliminary evidence, that the VieScope enables adequate endotracheal intubation in the pediatric setting. Further clinical studies are needed to confirm these results.

Delivery Room Management of Infants with Very Low Birth Weight in 3 European Countries-The Video Apgar Study

OBJECTIVE

To assess delivery room management of infants born preterm at 4 Level III perinatal centers in 3 European countries.

STUDY DESIGN

This was a prospective, multicenter observational study. Management at birth was video-recorded and evaluated (Interact version 9.6.1; Mangold-International, Arnstorf, Germany). Data were analyzed and compared within and between centers.

RESULTS

The infants (n = 138) differed significantly with respect to the median (25%, 75%) birth weight (grams) (Center A: 1200 [700, 1550]; Center B: 990 [719, 1240]; Center C: 1174 [835, 1435]; Center D: 1323 [971, 1515] [B vs A, C, D: P < .05]), gestational week (Center A: 28.4 [26.3, 30.0]; Center B: 27.9 [26.7, 29.6]; Center C: 29.3 [26.4, 31.0]; Center D: 30.3 [28.0, 31.9]), Apgar scores, rates of cesarean delivery, and time spent in the delivery room. Management differed significantly for frequency and drying time, rates of electrocardiographic monitoring, suctioning or stimulation, and for fundamental interventions such as time for achieving a reliable peripheral oxygen saturation signal (seconds) (Center A: 97.6 ± 79.3; Center B: 65.1 ± 116.2; Center C: 97.1 ± 67.0; Center D: 114.4 ± 140.5; B vs A, C, D: P < .001) and time for intubation (seconds) (Center A: 48.7 ± 4.2; Center B: 49.0 ± 30.7; Center C: 69.1 ±37.9; Center D: 65.1 ± 23.8; B vs D, P < .025). Mean procedural times did not meet guideline recommendations. The sequence of interventions was similar at all centers.

CONCLUSIONS

The Video Apgar Study showed great variability in and between 4 neonatal centers in Europe. The study also showed it is difficult to adhere to published guidelines for recommended times for important, basic measures such as peripheral oxygen saturation measurements and intubation.

Airway management in children with hemifacial microsomia: a restropective study of 311 cases

Background

Hemifacial microsomia (HFM) is a congenital craniofacial malformation which is associated with difficult airway. Anesthesiologists may experience difficult intubation in children with HFM. Mandibular distraction could increase the length of the mandible. Theoretically, it should be advantageous to laryngeal view during tracheal intubation. This study reviewed airway management in children with HFM, assessed the efficiency of direct laryngoscopy versus airway-visualizing equipment during the tracheal intubation and determined whether mandibular distraction could improve the laryngoscopic view in children with HFM.

Methods

A retrospective review of cases involving children with HFM aged 5 to 17 years old underwent anesthesia from December 2016 to April 2019 at a single center was performed. The demographic data, preoperative airway assessments, procedure type, anesthetic technique, method of airway management, anesthetists’ comments on mask ventilation, laryngoscopy and intubation parameters were collected.

Results

At last, 136 HFM children entered this study, a total of 311 anesthesia procedures were completed during the study period. Face mask ventilation was possible for most of children except 1 child (bilateral involvement) required two practitioners. The success rates of intubation for the primary video laryngoscopy and fibroscopy were both 100%, but 79.5% for direct laryngoscopy (P < 0.001). 95 (38.9%) children who had difficult laryngoscopic view (DLV) were significantly correlated with failed direct laryngoscopy (P < 0.001). Airway-visualizing equipment (video laryngoscope and Fiberscope) was the primary airway technique in 3 (75%) bilaterally involved children. 60 children underwent both mandibular distraction osteogenesis and the removal of distractor. The laryngoscopic views improved in 26 (43%) children after treatment with mandibular distraction (P < 0.001).

Conclusions

Airway-visualizing equipment can be effectively utilized for intubation in HFM children with DLV. Mandibular distraction could improve the laryngeal view effectively.
