Abstract Objective: Difficult intubation is associated with an increasing number of endotracheal intubation attempts. Repeated endotracheal intubation attempts are in turn associated with an increased risk of adverse events. Clinical prediction tools to predict difficult airway have limited application in emergency airway situations. This study was performed to develop a new model for predicting difficult intubation in the emergency department.Methods: This retrospective study was conducted using an exploratory model at the Emergency Medicine of Ramathibodi Hospital, a university-affiliated super-tertiary care hospital in Bangkok, Thailand. The study was conducted from June 2018 to July 2020. The inclusion criteria were an age of ≥15 years and treatment by emergency intubation in the emergency department. Difficult intubation was defined as a Cormack–Lehane grade III or IV laryngoscopic view. The predictive model and prediction score for detecting difficult intubation were developed by multivariable regression analysis.Results: During the study period, 617 patients met the inclusion criteria; of these, 83 (13.45%) had difficult intubation. Five independent factors were predictive of difficult intubation. The difficult airway assessment score that we developed to predict difficult airway intubation had an accuracy of 89%. A score of >4 increased the likelihood ratio of difficult intubation by 7.62 times.Conclusion: A difficult airway assessment score of >4 was associated with difficult intubation.

Introduction: Unanticipated difficult intubation is an undesirable situation. Various bedside screening tests are routinely performed for predicting difficult airway. Although considered a surrogate indicator, difficult laryngoscopy is not the exact measure of intubation difficulty. We aimed to determine the best screening test for predicting difficult laryngoscopy and the association between difficult laryngoscopic view and difficult intubation. Methods: This prospective, observational study involved 314, ASA I/II adult patients requiring endotracheal intubation for various routine surgical procedures. Sternomental distance < 12 cm, thyromental distance < 6.5cm, inter-incisor distance < 3.5 cm, mandibular protrusion grade 3 and modified Mallampati class III/IV were the predictors of difficult laryngoscopy. Laryngoscopic view was defined as ‘difficult’ when the Cormack and Lehane grade was III/ IV. The sensitivity, specificity, positive and negative predictive values and accuracy of these predictors were compared to find out the best predictor. Requirement of >3 attempts for insertion of the tracheal tube was defined as ‘difficult intubation’. The association between difficult laryngoscopic view and difficult intubation was determined. Results: The sensitivity of the modified Mallampati class for predicting difficult laryngoscopy was highest (83%). Twelve (3.8%) patients had grade III laryngoscopic view and none had a grade of IV. Intubation was difficult in seven (2.2%) patients. Majority of patients (4 of 7) with difficult intubation had difficult laryngoscopic view (p<0.001). Conclusions: Modified Mallampati test was better for predicting difficult laryngoscopy compared to other bedside screeing tests. Difficult laryngoscopy could significantly predict difficult intubation in our patients.   Keywords: Airway evaluation; difficult intubation; difficult laryngoscopy; modified Mallampati class; Nepalese patients; sensitivity.

Difficult Endotracheal Intubation

Abstract Background Current predictors for evaluating difficult endotracheal intubation had poor accessibility or sensitivity at the emergency department, so we evaluated the incidence and predictive factors, then built an easy-to-use predictive formula. Methods This was a 17-month prospective observational study. For the 110 patients, difficult airway was defined as Cormack & Lehane classification grade III and IV at first attempt of intubation. The univariate associations between patient characteristics and difficult endotracheal intubation were then analyzed, and the significantly associated factors were included in a multivariate binary logistic regression model then a predictive formula was generated. Generalized association plot (GAP) was used to show the relationship between each variable. Results The incidence of difficult intubation in our study was 35.5%. In the difficult airway group, significantly higher rates (p < 0.05) of high body mass index (BMI); double chin; thick, short neck; Mallampati difficulty; smaller inter-incisors distance; smaller thyromental distance; and upper airway obstruction were noted. Finally, a predictive formula for difficult intubation was successfully established by the combination of four predictors: BMI (odds ratio [OR] = 1.270), thyromental distance (OR = 0.614), upper airway obstruction (OR = 4.038), and Mallampati difficulty (OR = 5.163). A cut-off score of 4 provided the best sensitivity (79.5%) and specificity (81.7%)(95% CI: 0.794 to 0.938). Conclusions Our predictive formula could be used by emergency physicians to quickly identify and carefully manage patients with potentially difficult intubation. Early expert consultation could be sought when necessary.

BACKGROUND First-pass success is the successful intubation on the first attempt. It is the desired goal of emergency intubation and failure to achieve it may increase the risk of adverse effects. With failure of first pass intubation, life-threatening complications occur, commonly in critically ill patients. The aim of this study is to determine the association between the success of first-pass intubation and frequency of adverse events during endotracheal intubation. METHODS A cross sectional analytical study was done in a tertiary care hospital between October 2016 and October 2017. 100 failed first-pass intubation cases and 100 successful first-pass intubation cases were evaluated for factors associated with failed first-pass intubation and frequency of adverse events following intubation. RESULTS The groups were matched with respect to gender, induction agent use, fentanyl use and type of laryngoscope used. Mean age in failed first-pass intubation group was 5.61 years higher than subjects in successful first-pass intubation group (P = 0.016). Proportion of subjects with difficult airway was 19 % in failed first-pass intubation group and 3 % in successful first-pass intubation (P < 0.001). Failed first-pass intubation cases had higher frequency of adverse events like oesophageal intubation (9 % vs. 0 %), aspiration (7 % vs. 1 %), cuff leakage (2 % vs. 0 %) and hypotension (7 % vs. 1 %) compared to successful first-pass intubation cases. CONCLUSIONS The frequency of adverse events was high in failed first-pass intubation. Older age and presence of difficult airway were factors significantly associated with failed first-pass intubation.

Adequate Oxygenation

In difficult airway situations, the next step of the airway management method is selected according to the prior presence of difficulties in mask ventilation and endotracheal intubation. It is important for the practitioner to be calm, quick in judgment, and take action in cases of difficult intubation. Recently, high-flow nasal oxygenation has been rapidly introduced into the anesthesiology field. This technique could extend the safe apnea time to desaturation. Especially, it maintains adequate oxygenation even in apnea and allows time for intubation or alternative airway management. We report two cases in which high-flow nasal oxygenation was implemented in the middle of the induction process after quick judgment by clinicians. High-flow nasal oxygenation was successfully used to assist in prolonging the safe apnea time during delicate airway securing attempts.

Background. Emergency medical care starts with airway assessment and intervention management. Endotracheal intubation is the definitive airway management in the emergency department (ED) for patients requiring a definitive airway. Successful first pass is recommended as the main objective of emergency intubation. There exists no published research regarding the success rates or complications that occur within Ethiopian hospitals emergency department intubation practice. Objective. This study aimed to assess the success rate of emergency intubations in a tertiary hospital, Addis Ababa, Ethiopia. Methodology. This was a single institute retrospective documentation review on intubated patients from November 2017 to November 2018 in the emergency department of Addis Ababa Burn Emergency and Trauma Hospital. All intubations during the study period were included. Data were collected by trained data collectors from an intubation documentation sheet. Result. Of 15,933 patients seen in the department, 256 (1.6%) patients were intubated. Of these, 194 (74.9%) were male, 123 (47.5%) sustained trauma, 65 (25.1%) were medical cases, and 13(5%) had poisoning. The primary indications for intubation were for airway protection (160 (61.8%)), followed by respiratory failure (72(27.8%)). One hundred and twenty-nine (49.8%) had sedative-only intubation, 110 (42.5%) had rapid sequence intubation, and 16 (6.2%) had intubation without medication. The first-pass success rate in this sample was 70.3% (180/256), second-pass 21.4% (55/256), and third-pass 7.4% (19/256), while the overall success rate was 99.2% (254/256). Hypoxia was the most common complication. Conclusion. The intubation first-pass success rate was lower than existing studies, but the overall intubation success rate was satisfactory.
