Intubation In Emergency Department Research Articles

Use of insitu simulation to improve team performance and utilization of a rapid sequence intubation checklist.

Intubation checklists have emerged as tools to reduce adverse events and improve efficiency during rapid sequence intubation (RSI) in pediatric emergency departments (PEDs). This study aimed to use multidisciplinary simulation (SIM) training as an educational tool to improve PED team performance during RSI scenarios through utilization of an RSI checklist. We created a checklist modeled after previously published PED checklists. PED multidisciplinary teams participated in video-recorded SIM training sessions involving a scenario requiring intubation three times, first without interruption then while receiving our intervention of rapid-cycle deliberate practice (RCDP) debriefing focusing on checklist utilization and team dynamics. Learners went through the scenario once more uninterrupted to apply learned skills. Team performance was evaluated via video review using the Simulation Team Assessment Tool (STAT) focusing on airway management and human factors sections. Scores were compared before and after intervention along with pre- and postintervention surveys. A total of 483 learners participated in 64 SIM training sessions, 44 of whom met inclusion criteria and were included for data analysis. Scores increased postintervention for airway management, human factors and in total. Least-squares mean differences for total, airway, and human factors scores were 9.55 (95% confidence interval [CI] 7.24-11.85), 4.22 (95% CI 2.91-5.52), and 5.33 (95% CI 3.86-6.8), respectively, which was statistically significant with p-value of <0.001 across all categories. Surveys demonstrated improved role understanding and checklist utilization comfort postintervention. This study supports the benefit of multidisciplinary SIM training with RCDP-style methodology as an educational method for improving airway management, teamwork skills, and RSI checklist utilization for PED staff. Incorporation of additional maintenance SIM sessions for ongoing education is likely to be further beneficial and would allow evaluation of degradation of skills over time following initial training.

SPICT tool among intubated elderly patients at emergency department

BackgroundThe global rise in the aging population necessitates a proactive approach to palliative care, with a substantial gap between the demand for and access to such care. The Supportive and Palliative Care Indicators Tool (SPICT) has emerged as a valuable instrument for identifying patients at risk of deterioration and death, enhancing the timely initiation of palliative care. This study aimed to investigate the characteristics and outcomes of patients aged 60 and above who got intubated in the emergency department (ED), with and without fulfilling SPICT criteria. MethodsThis retrospective single-center study was conducted at a tertiary care teaching hospital in Thailand. The research involved 408 adults aged 60 and older who underwent ED intubation and subsequent admission. Baseline characteristics and follow-up data were collected, encompassing vital signs, comorbidities, and SPICT criteria. Mortality rates between SPICT criteria-fulfilled and non-fulfilled groups were compared. ResultsOut of 408 analyzed patients, SPICT criteria were met by 39.7 % of patients, exhibiting distinctive features such as a higher respiratory rate and lower diastolic blood pressure. Hypertension and diabetes mellitus were most prevalent comorbidities. Respiratory and neurological disorders were the leading final diagnoses. The overall in-hospital mortality rate was 28 %, significantly higher in the SPICT criteria-fulfilled group compared to the non-fulfilled group (34.0 % vs 23.6 %, P = 0.022). SPICT criteria demonstrated moderate sensitivity (48.7 %) and specificity (63.7 %) for predicting mortality. ConclusionSPICT criteria identified elderly patients at an elevated mortality risk following intubation in the emergency setting. The early implementation of SPICT as a screening tool for identifying palliative care candidates is advocated for more effective advance care planning.

A Comparison of Ketamine to Midazolam for the Management of Acute Behavioral Disturbance in the Out-of-Hospital Setting

ObjectiveAcute behavioral disturbance is characterized by altered mental status and psychomotor agitation. Pharmacological sedation may be required, risking potential respiratory compromise. We compared the need for emergent airway support following administration of midazolam or ketamine to treat acute behavioral disturbance in the prehospital setting. MethodsIn this retrospective cohort study of patients with acute behavioral disturbance in an urban Emergency Medical Service (EMS) system between 2017-2021, we compared the likelihood of prehospital advanced airway management following administration of midazolam or ketamine. Advanced airway management was defined as prehospital endotracheal intubation or supraglottic airway insertion. ResultsAmong 376 eligible patients, the median age was 35; and 78% were male. The most common etiologies of acute behavioral disturbance were substance use (51%), trauma (18%), and presumed postictal agitation (11%). In all, 162 patients (43%) initially received midazolam and 214 (57%) ketamine. The frequency of advanced airway management was similar between these respective groups (12% [n=19] vs 11% [n=24], difference 0.5%, 95% CI -6.0% to 7.0%). Adjusted for potential confounders, the odds of receiving advanced airway management did not differ between midazolam and ketamine (aOR 1.02, 95% CI 0.44 to 2.38), nor were differences observed in emergency department intubation rates (14% in midazolam recipients, 11% for ketamine) or overall mortality (2% in midazolam recipients, 1% for ketamine). ConclusionIn this cohort study of patients with acute behavioral disturbance, emergent airway support nor other outcomes differed following prehospital treatment with midazolam or ketamine.

47 Emergency Department Intubations in Older Adults and Associated Mortality

47 Emergency Department Intubations in Older Adults and Associated Mortality

Comparing the effectiveness and safety of videolaryngoscopy and direct laryngoscopy for endotracheal intubation in the paediatric emergency department: a systematic review and meta-analysis.

Endotracheal intubation is an uncommon procedure for children in the emergency department but can be technically difficult and cause significant adverse effects. Videolaryngoscopy (VL) offers improved first-pass success rates over direct laryngoscopy (DL) for both adults and children undergoing elective surgery. This systematic review was designed to evaluate current evidence regarding how the effectiveness and safety of VL compares to DL for intubation of children in emergency departments. Four databases (MEDLINE, Embase, CENTRAL and Web of Science) were searched on 11th May 2023 for studies comparing first-pass success of VL and DL for children undergoing intubation in the emergency department. Studies including adult patients or where intubation occurred outside of the emergency department were excluded. Quality assessment of included studies was carried out using the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I) tool. Meta-analysis was undertaken for first-pass success and adverse event rate. Ten studies met the inclusion criteria representing 5,586 intubations. All included studies were observational. Significantly greater first-pass success rate was demonstrated with VL compared to DL (OR 1.64, 95% CI [1.21-2.21], p = 0.001). There was no significant difference in risk of adverse events between VL and DL (OR 0.79, 95% CI [0.52-1.20], p = 0.27). The overall risk of bias was moderate to serious for all included studies. VL can offer improved first-pass success rates over DL for children intubated in the emergency department. However, the quality of current evidence is low and further randomised studies are required to clarify which patient groups may benefit most from use of VL. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=415039, Identifier CRD42023415039.

Direct Laryngoscopy Versus Video Laryngoscopy for Intubation in Critically Ill Patients: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Trials.

Given the uncertainty regarding the optimal approach to laryngoscopy for the intubation of critically ill adult patients, we conducted a systematic review and meta-analysis to compare video laryngoscopy (VL) vs. direct laryngoscopy (DL) for intubation in emergency department and ICU patients. We searched MEDLINE, PubMed, Embase, Cochrane Library, and unpublished sources, from inception to February 27, 2024. We included randomized controlled trials (RCTs) of critically ill adult patients randomized to VL compared with DL for endotracheal intubation. Reviewers screened abstracts, full texts, and extracted data independently and in duplicate. We pooled data using a random-effects model, assessed risk of bias using the modified Cochrane tool and certainty of evidence using the Grading Recommendations Assessment, Development, and Evaluation approach. We pre-registered the protocol on PROSPERO (CRD42023469945). We included 20 RCTs (n = 4569 patients). Compared with DL, VL probably increases first pass success (FPS) (relative risk [RR], 1.13; 95% CI, 1.06-1.21; moderate certainty) and probably decreases esophageal intubations (RR, 0.47; 95% CI, 0.27-0.82; moderate certainty). VL may result in fewer aspiration events (RR, 0.74; 95% CI, 0.51-1.09; low certainty) and dental injuries (RR, 0.46; 95% CI, 0.19-1.11; low certainty) and may have no effect on mortality (RR, 0.97; 95% CI, 0.88-1.07; low certainty) compared with DL. In critically ill adult patients undergoing intubation, the use of VL, compared with DL, probably leads to higher rates of FPS and probably decreases esophageal intubations. VL may result in fewer dental injuries as well as aspiration events compared with DL with no effect on mortality.

Association between multiple intubation attempts and complications during emergency department airway management: A national emergency airway registry study

ObjectivePeri-intubation complications are important sequelae of airway management in the emergency department (ED). Our objective was to quantify the increased risk of complications with multiple attempts at emergency airway intubation in the ED. MethodsThis is a secondary analysis of a prospectively collected multicenter registry (National Emergency Airway Registry) consisting of attempted ED intubations among subjects aged >14 years. The primary exposure variable was the number of intubation attempts. The primary outcome measure was the occurrence of peri-intubation major complications within 15 min of intubation including hypotension, hypoxemia, vomiting, dysrhythmias, cardiac arrest, esophageal intubation, and failed airway with cricothyrotomy. We constructed multivariable logistic regression models to determine the associations between complications and the number of intubation attempts while controlling for measured pre-exposure variables. ResultsThere were 19,071 intubations in the NEAR database, of which 15,079 met inclusion for this analysis. Of these, 13,459 were successfully intubated on the first attempt, 1,268 on the second attempt, 269 on the third attempt, 61 on the fourth attempt, and 22 on the fifth or more attempt. A complication occurred in 2,137 encounters (14 %). Major complications accompanied 1,968 encounters (13 %) whereas minor complications affected 315 encounters (2 %). The most common major complication was hypoxia. In our multivariable logistic regression model, odds ratios with 95 % confidence intervals for the occurrence of major complications for multiple attempts compared to first-pass success were 4.4 (3.6–5.3), 7.4 (5.0–10.7), 13.9 (5.6–34.3), and 9.3 (2.1–41.7) for attempts 2–5+ (reference attempt 1), respectively. ConclusionsWe found an independent association between the number of intubation attempts among ED patients undergoing emergency airway intubation and the risk of complications.

A risk prediction model for efficient intubation in the emergency department: A 4-year single-center retrospective analysis.

To analyze the risk factors associated with intubated critically ill patients in the emergency department (ED) and develop a prediction model by machine learning algorithms. This study was conducted in an academic tertiary hospital in Hangzhou, China. Critically ill patients admitted to the ED were retrospectively analyzed from May 2018 to July 2022. The demographic characteristics, distribution of organ dysfunction, parameters for different organs' examination, and status of mechanical ventilation were recorded. These patients were assigned to the intubation and non-intubation groups according to ventilation support. We used the eXtreme Gradient Boosting (XGBoost) algorithm to develop the prediction model and compared it with other algorithms, such as logistic regression, artificial neural network, and random forest. SHapley Additive exPlanations was used to analyze the risk factors of intubated critically ill patients in the ED. Of 14,589 critically ill patients, 10,212 comprised the training group and 4377 comprised the test group; 2289 intubated patients were obtained from the electronic medical records. The mean age, mean scores of vital signs, parameters of different organs, and blood oxygen examination results differed significantly between the two groups (p<0.05). The white blood cell count, international normalized ratio, respiratory rate, and pH are the top four risk factors for intubation in critically ill patients. Based on the risk factors in different predictive models, the XGBoost model showed the highest area under the receiver operating characteristic curve (0.84) for predicting ED intubation. For critically ill patients in the ED, the proposed model can predict potential intubation based on the risk factors in the clinically predictive model.

First-Attempt Success Between Anatomically and Physiologically Difficult Airways in the National Emergency Airway Registry.

In the emergency department (ED), certain anatomical and physiological airway characteristics may predispose patients to tracheal intubation complications and poor outcomes. We hypothesized that both anatomically difficult airways (ADAs) and physiologically difficult airways (PDAs) would have lower first-attempt success than airways with neither in a cohort of ED intubations. We performed a retrospective, observational study using the National Emergency Airway Registry (NEAR) to examine the association between anticipated difficult airways (ADA, PDA, and combined ADA and PDA) vs those without difficult airway findings (neither ADA nor PDA) with first-attempt success. We included adult (age ≥14 years) ED intubations performed with sedation and paralysis from January 1, 2016 to December 31, 2018 using either direct or video laryngoscopy. We excluded patients in cardiac arrest. The primary outcome was first-attempt success, while secondary outcomes included first-attempt success without adverse events, peri-intubation cardiac arrest, and the total number of airway attempts. Mixed-effects models were used to obtain adjusted estimates and confidence intervals (CIs) for each outcome. Fixed effects included the presence of a difficult airway type (independent variable) and covariates including laryngoscopy device type, intubator postgraduate year, trauma indication, and patient age as well as the site as a random effect. Multiplicative interaction between ADAs and PDAs was assessed using the likelihood ratio (LR) test. Of the 19,071 subjects intubated during the study period, 13,938 were included in the study. Compared to those without difficult airway findings (neither ADA nor PDA), the adjusted odds ratios (aORs) for first-attempt success were 0.53 (95% CI, 0.40-0.68) for ADAs alone, 0.96 (0.68-1.36) for PDAs alone, and 0.44 (0.34-0.56) for both. The aORs for first-attempt success without adverse events were 0.72 (95% CI, 0.59-0.89) for ADAs alone, 0.79 (0.62-1.01) for PDAs alone, and 0.44 (0.37-0.54) for both. There was no evidence that the interaction between ADAs and PDAs for first-attempt success with or without adverse events was different from additive (ie, not synergistic/multiplicative or antagonistic). Compared to no difficult airway characteristics, ADAs were inversely associated with first-attempt success, while PDAs were not. Both ADAs and PDAs, as well as their interaction, were inversely associated with first-attempt success without adverse events.

The diagnostic accuracy of point-of-care ultrasound parameters for airway assessment in patients undergoing intubation in emergency department—an observational study

BackgroundEndotracheal intubation is an essential resuscitative procedure in the emergency setting. Airway assessment parameters such as the Mallampati classification are difficult to perform in an emergency setting. As point-of-care ultrasound (POCUS) assessment of airway parameters does not require patients to perform any mandatory action, ultrasound may become the potential first-line noninvasive airway assessment tool in the emergency department (ED). The use of POCUS in the ED has not been sufficiently studied. Using POCUS in airway assessment for predicting difficult intubation may be the next step in successful airway management.MethodologyThe study was an observational study conducted at the ED of the All India Institute of Medical Sciences (Rishikesh). The treating emergency physician recorded the patient history and systemic examination along with an indication for intubation. The POCUS assessment of airway parameters pre-epiglottis to epiglottic vocal cord ratio (Pre-E/E-VC), tongue thickness, hyomental distance, and distance from skin to the hyoid bone was performed by the study investigator. During laryngoscopy, Cormack-Lehane (CL) grading was assessed. The data was entered and analyzed.ResultsSeventy patients who required intubation in the ED were enrolled in the study. Among the study population, 48.6%, 28.6%, 14.3%, 1.4%, and 7.1% were classified with the following CL grading: 1, 2a, 2b, 3a, and 3b, respectively. At a cutoff of ≥ 1.86, Pre-E/E-VC predicts difficult laryngoscopy (AUC 0.835) with a sensitivity of 83% and a specificity of 94%. At a cutoff of ≥ 5.98 cm, tongue thickness predicts difficult laryngoscopy (AUC 0.78) with a sensitivity of 83% and a specificity of 88%. At a cutoff of hyomental distance ≤ 6 cm, it predicts difficult laryngoscopy with a sensitivity of 83% and a specificity of 88%. All parameters can act as a promising tool for predicting difficult laryngoscopy, with the single best parameter being Pre-E/E-VC.ConclusionAssessment of the airway with POCUS may be helpful to the emergency physician when the clinical airway assessment parameters fail to predict difficult laryngoscopy as most patients requiring intubation are uncooperative. Assessment of the parameters in our study Pre-E/E-VC, tongue thickness, and hyomental distance can act as a promising tool for predicting difficult laryngoscopy in the emergency scenario.

MONTH Score in Predicting Difficult Intubations in Emergency Department; a Prognostic Accuracy Study.

MONTH Difficult Laryngoscopy Score was developed for effectively identifying difficult intubations in the emergency department (ED). This study aimed to evaluate the accuracy of MONTH Score in predicting difficult intubations in ED. We prospectively collected data on all patients undergoing intubation in the ED of Ramathibodi Hospital, Bangkok, Thailand. The screening performance characteristics of the MONTH score in identifying the difficult intubation in ED were analyzed. All data were analyzed using STATA software version 18.0. 324 intubated patients with the median age of 73 (63-82) years were studied (63.58% male). The proportion of difficult intubations was 19.44%. The sensitivity and specificity of MONTH in predicting difficult intubations were 74.6% (95% CI: 61.6%-85.0%) and 92.8% (95% CI: 89.0%-95.6%), respectively. These measures in subgroup of patients with Intubation Difficulty Scale (IDS) score ≥ 6 were 44.1% (95%CI: 31.2-57.6) and 98.5% (95% CI: 96.2%- 99.6%), respectively. The area under the receiver operation characteristic (ROC) curve of MONTH in predicting difficult intubations was 0.895 (95% CI: 0.856- 0.926). It seems that the MONTH Difficult Laryngoscopy Score could be considered as a tool with high specificity and positive predictive values in identifying cases with difficult intubations in ED.

Factors associated with first pass success rate during intubation in the emergency department: a systematic review

Many emergency departments are now evaluating the quality of airway management, with the first-pass success rate being a widely used indicator of competence that has been linked to adverse event rates. The present study aimed to quantify adverse events related to endotracheal intubation in emergency departments, focusing on the first-pass success rate.We conducted a thorough search of MEDLINE, EMBASE, and PubMed using keywords such as \&amp;quot;multiple intubation attempts,\&amp;quot; \&amp;quot;intubation,\&amp;quot; \&amp;quot;first-pass success,\&amp;quot; and \&amp;quot;learning curve\&amp;quot; to identify relevant research. Our search was further expanded to include references from the identified articles. We collected and assessed citations spanning a twenty-year period from 2000 to 2020, involving emergency airway management by both prehospital and in-hospital clinicians.Eight articles were included in the final review. Among them, three trials evaluated the impact of the number of intubation attempts on the complication rate, yielding odds ratios of 6.7 (n = 2284), 4.7 (n = 1903), and 4.5 (n = 2616). Multiple intubation attempts were found to increase the risk of complications, a finding supported by a 2004 analysis of 2833 airway management incidents. In this analysis, more than one intubation attempt was associated with a fivefold increase in the overall complication rate.First-pass success rates varied between 71% and 87.5% for prehospital physicians and between 60% and 97% for in-hospital physicians. Achieving first-pass success was shown to reduce problems and increase the likelihood of sufficient oxygenation. Conversely, multiple intubation attempts were correlated with a higher rate of unfavorable outcomes.

Mild traumatic brain injury: not always a mild injury.

In general, risk of mortality after trauma correlates with injury severity. Despite arriving in relatively stable clinical condition, however, some patients are at risk of death following mild traumatic brain injury (TBI). The study objective was delineation of patients who die in-hospital following mild isolated TBI in order to inform Emergency Department (ED) disposition and care discussions with patients and families. In this retrospective cohort study, patients from the National Trauma Data Bank (NTDB) (2007-2018) were included if they were injured by blunt trauma and sustained a mild TBI (defined as Head Abbreviated Injury Scale [AIS] score of 1 or 2 and arrival Glasgow Coma Scale [GCS] score of 13-15). Exclusions were severe associated injuries (extracranial AIS > 2); transfers; and missing data. Patients were defined by in-hospital mortality: Survivors vs. Mortalities. Demographics, clinical/injury data, and the outcomes were collected and compared with univariate analysis. Multivariate analysis established independent factors associated with in-hospital mortality following mild TBI. In total, 932,107 patients (10% of NTDB population) met study criteria: 928,542 (99.6%) Survivors and 3,565 (0.4%) Mortalities. In general, comorbidities (including home anticoagulation, cardiac disease, and diabetes mellitus) were significantly more common among patients who died (p < 0.001), although drug and alcohol intoxication on arrival were more common among Survivors (16% vs. 7%, p < 0.001; 13% vs. 10%, p < 0.001). In terms of insurance status, Private/Commercial insurance was more common among Survivors (39% vs. 20%, p < 0.001) while Governmental Insurance was more common among Mortalities (55% vs. 36%, p < 0.001). On multivariate analysis, age ≥ 65 was most strongly associated with death (OR 26.43, p < 0.001), followed by ED intubation (OR 10.08, p < 0.001), admission hypotension (OR 4.55, p < 0.001), and comorbidities, particularly end-stage renal disease (ESRD) (OR 3.03, p < 0.001) and immunosuppression (OR 2.18, p < 0.001). Survivors differed substantially from Mortalities after mild TBI in terms of comorbidities, intoxicants, and insurance status. Independent variables most strongly associated with in-hospital death following mild head injury included age ≥ 65, intubation in the ED, admission hypotension, and comorbidities (particularly ESRD and immunosuppression). Increased clinical vigilance, including a mandatory period of clinical observation, for patients with these risk factors should be considered to optimize outcomes and potentially mitigate death after mild TBI.

Effect of Bougie Use on First-Attempt Success in Tracheal Intubations: A Systematic Review and Meta-Analysis

The use of a bougie, a flexible endotracheal tube introducer, has been proposed to optimize first-attempt success in emergency department intubations. We aimed to evaluate the available evidence on the association of bougie use in the first attempt and success in tracheal intubations. This was a systematic review and meta-analysis of studies that evaluated first-attempt success between adults intubated with a bougie versus without a bougie (usually with a stylet) in all settings. Manikin and cadaver studies were excluded. A medical librarian searched Ovid Cochrane Central, Ovid Embase, Ovid Medline, Scopus, and Web of Science for randomized controlled trials and comparative observational studies from inception to June 2023. Study selection and data extraction were done in duplicate by 2 independent reviewers. We conducted a meta-analysis with random-effects models, and we used GRADE to assess the certainty of evidence at the outcome level. We screened a total of 2,699 studies, and 133 were selected for full-text review. A total of 18 studies, including 12 randomized controlled trials, underwent quantitative analysis. In the meta-analysis of 18 studies (9,151 patients), bougie use was associated with increased first-attempt intubation success (pooled risk ratio [RR] 1.11, 95% confidence interval [CI] 1.06 to 1.17, low certainty evidence). Bougie use was associated with increased first-attempt success across all analyzed subgroups with similar effect estimates, including in emergency intubations (9 studies; 8,070 patients; RR 1.11, 95% CI 1.05 to 1.16, low certainty). The highest point estimate favoring the use of a bougie was in the subgroup of patients with Cormack-Lehane III or IV (5 studies, 585 patients, RR 1.60, 95% CI 1.40 to 1.84, moderate certainty). In this meta-analysis, the bougie as an aid in the first intubation attempt was associated with increased success. Despite the certainty of evidence being low, these data suggest that a bougie should probably be used first and not as a rescue device in emergency intubations.

A taxonomy of key performance errors for emergency intubation

Study objectiveCurrently the videographic review of emergency intubations is an unstructured, qualitative process. We created a taxonomy of errors that impede the optimal procedural performance of emergency intubation. MethodsThis was a prospective, observational, study reviewing a convenience sample of deidentified laryngoscopy recordings of emergency department intubations that were qualitatively flagged before the study as demonstrating suboptimal technique. These videos were coded for the presence of 13 predetermined performance errors. Our primary outcome was the incidence of each of these specified errors during emergency intubation. Errors fell into 3 categories: errors of structure recognition during laryngoscope insertion, errors of vallecula manipulation, and errors of device delivery. ResultsA total of 100 intubation attempts were reviewed. The most common error was inadequate lifting force with the blade tip in the vallecula which lowered the percent of glottic opening, occurring in 45% of the attempts. The least common performance error was the premature removal of the laryngoscope during bougie placement, occurring in only 9% of the videos. ConclusionWe developed a taxonomy of 13 performance errors of laryngoscopy. Further study is warranted to determine how to best incorporate these into emergency airway training and the airway review process.

Effect of prehospital intubation on mortality rates in patients with traumatic brain injury: A systematic review and meta-analysis.

It is unclear if prehospital intubation improves survival in patients with traumatic brain injury. We performed a systematic review and meta-analysis to assess the impact of prehospital intubation on mortality rates of traumatic brain injury. PubMed, CENTRAL, Web of Science, and Embase databases were searched without any language restriction up to 20 June 2022 for all types of comparative studies reporting survival of traumatic brain injury patients based on prehospital intubation. In total, 18 studies with 41,185 patients were eligible for inclusion. Meta-analysis showed that traumatic brain injury patients receiving prehospital intubation had higher odds of mortality as compared to those not receiving prehospital intubation. Meta-analysis of adjusted data also indicated that prehospital intubation was associated with increased odds of mortality in traumatic brain injury patients. The results did not change on sensitivity analysis. Subgroup analysis based on study type, the severity of traumatic brain injury, inclusion of isolated traumatic brain injury, emergency department intubation in the control group, and prehospital intubation group sample size demonstrated variable results. Heterogeneous data from mostly observational studies demonstrates higher mortality rates among traumatic brain injury patients receiving prehospital intubation. The efficacy of prehospital intubation is difficult to judge without taking into account multiple confounding factors.

Introduction of Infection Prevention Tracheal Intubation Protocol during the COVID-19 Pandemic Is Not Associated with First-Pass Success Rates of Endotracheal Intubation in the Emergency Department: A Before-and-After Comparative Study.

Aerosols and droplets have put healthcare workers performing airway management at high risk of contracting coronavirus disease 2019 (COVID-19). Experts have developed endotracheal intubation (ETI) guidelines and protocols to protect intubators from infection. We aimed to determine whether changes in the emergency department (ED) intubation protocol to prevent COVID-19 infection were associated with first-pass success (FPS) rates in ETI. We used data from the airway management registries in two academic EDs. The study was divided into pre-pandemic (January 2018 to January 2020) and pandemic (February 2020 to February 2022) periods. We selected 2476 intubation cases, including 1151 and 1325 cases recorded before and during the pandemic, respectively. During the pandemic, the FPS rate was 92.2%, which did not change significantly, and major complications increased slightly but not significantly compared with the pre-pandemic period. The OR for the FPS of applying infection prevention intubation protocols was 0.72 (p = 0.069) in a subgroup analysis, junior emergency physicians (PGY1 residents) had an FPS of less than 80% regardless of pandemic protocol implementation. The FPS rate of senior emergency physicians in physiologically difficult airways decreased significantly during the pandemic (98.0% to 88.5%). In conclusion, the FPS rate and complications for adult ETI performed by emergency physicians using COVID-19 infection prevention intubation protocols were similar to pre-pandemic conditions.

Prehospital Ketamine Administration for Trauma Patients Results in more ED Intubations

Introduction:The use of ketamine in the prehospital setting has increased with EMS providers. Adverse effects of prehospital ketamine administration have not been well-established in the trauma population. The objective of this study was to evaluate the effects of pre-hospital ketamine on trauma patients presenting to a Level 1 trauma center. This study hypothesized that respiratory depression or oversedation from ketamine would increase the number of ED (Emergency Department) intubations.Method:A retrospective chart review of adult trauma patients receiving prehospital ketamine from 2016-2021 was performed. Patients with severe traumatic brain injuries were excluded. A 1:1 propensity match was performed of patients with similar demographics, injury severity, and mechanism of injury who did not receive prehospital ketamine. Univariate analyses were used to compare the groups. The primary outcome was the incidence of intubation in the Emergency Department.Results:Seventy-four trauma patients who received prehospital ketamine were identified. The average ketamine dose was 39 mg IV and 226.4 mg IM. 35.1% of patients received ketamine for pain while 29.7% received it for agitation. The ED intubation rate was higher in the prehospital ketamine group with 17.6% (n=13/74) requiring intubation as compared with 4.8% (n=3/63) who did not receive ketamine (p=0.03). Patients who required intubation in the ED had higher average doses of both IV/IO (37.7 +/- 4.8 mg vs. 55.0 +/- 24.2 mg) and IM ketamine (196.4 +/- 41.7 mg vs 290.0 +/- 41.3 mg).Conclusion:ED intubation rate was higher in the ketamine group. Patients that were intubated had received higher ketamine doses on average. Further studies are needed to understand and refine prehospital dosing and indication protocols to allow for more efficacious utilization of pre-hospital ketamine in trauma patients. A multicenter trial is ongoing.
