RESUMO
INTRODUCTION: Emergency clinical research has played an important role in improving outcomes for acutely ill patients. This is due in part to regulatory measures that allow Exception From Informed Consent (EFIC) trials. The Food and Drug Administration (FDA) requires sponsor-investigators to engage in community consultation and public disclosure activities prior to initiating an Exception From Informed Consent trial. Various approaches to community consultation and public disclosure have been described and adapted to local contexts and Institutional Review Board (IRB) interpretations. The COVID-19 pandemic has precluded the ability to engage local communities through direct, in-person public venues, requiring research teams to find alternative ways to inform communities about emergency research. METHODS: The PreVent and PreVent 2 studies were two Exception From Informed Consent trials of emergency endotracheal intubation, conducted in one geographic location for the PreVent Study and in two geographic locations for the PreVent 2 Study. During the period of the two studies, there was a substantial shift in the methodological approach spanning across the periods before and after the pandemic from telephone, to in-person, to virtual settings. RESULTS: During the 10 years of implementation of Exception From Informed Consent activities for the two PreVent trials, there was overall favorable public support for the concept of Exception From Informed Consent trials and for the importance of emergency clinical research. Community concerns were few and also did not differ much by method of contact. Attendance was higher with the implementation of virtual technology to reach members of the community, and overall feedback was more positive compared with telephone contacts or in-person events. However, the proportion of survey responses received after completion of the remote, live event was substantially lower, with a greater proportion of respondents having higher education levels. This suggests less active engagement after completion of the synchronous activity and potentially higher selection bias among respondents. Importantly, we found that engagement with local community leaders was a key component to develop appropriate plans to connect with the public. CONCLUSION: The PreVent experience illustrated operational advantages and disadvantages to community consultation conducted primarily by telephone, in-person events, or online activities. Approaches to enhance community acceptance included partnering with community leaders to optimize the communication strategies and trust building with the involvement of Institutional Review Board representatives during community meetings. Researchers might need to pivot from in-person planning to virtual techniques while maintaining the ability to engage with the public with two-way communication approaches. Due to less active engagement, and potential for selection bias in the responders, further research is needed to address the costs and benefits of virtual community consultation and public disclosure activities compared to in-person events.
RESUMO
BACKGROUND: We investigated how syndromic versus nonsyndromic forms of micrognathia impacted difficult intubation outcomes in children. Primary outcome was the first-attempt success rate of tracheal intubation, secondary outcomes were number of intubation attempts and complications. We hypothesized that syndromic micrognathia would be associated with lower first-attempt success rate. METHODS: In micrognathic patients enrolled in the Pediatric Difficult Intubation Registry (08/2012-03/2019) we retrospectively compared demographic and clinical characteristics between children with nonsyndromic and syndromic micrognathia using standardized mean differences (SMD) and assessed the association of the presence of syndrome with the primary and secondary outcomes using propensity score matching analysis with and without matching for airway assessment findings. RESULTS: Nonsyndromic patients (628) were less likely to have additional airway abnormalities. Syndromic patients (216) were less likely to have unanticipated difficult intubation (2% vs. 20%, SMD 0.59). First-attempt success rates of intubation were: 38% in the syndromic versus 34% in the nonsyndromic group (odds ratio [OR] 1.18; 95% confidence intervals [95% CI] 0.74, 1.89; p = .478), and 37% versus 37% (OR 0.99; 95% CI 0.66, 1.48; p = .959). Median number of intubation attempts were 2 (interquartile range [IQR]: 1, 3; range: 1, 8) versus 2 (IQR: 1, 3; range 1, 12) (median regression coefficient = 0; 95% CI: -0.7, 0.7; p = .999) and 2 (IQR: 1, 3; range: 1, 12) versus 2 (IQR: 1, 3; range 1, 8) (median regression coefficient = 0; 95% CI: -0.5, 0.5; p = .999). Complication rates were 14% versus 22% (OR 0.6; 95% CI 0.34, 1.04; p = .07) and 16% versus 21% (OR 0.71; 95% CI 0.43, 1.17; p = .185). CONCLUSIONS: Presence of syndrome was not associated with lower first-attempt success rate on intubation, number of intubation attempts, or complication rate among micrognathic patients difficult to intubate, despite more associated craniofacial abnormalities. Nonsyndromic patients were more likely to have unanticipated difficult intubations, first attempt with direct laryngoscopy.

AIM: In cases of out-of-hospital cardiac arrests (OHCA) occurring at home, Japanese emergency medical services personnel decide whether to provide treatment on the scene or during transport based on their judgment. This study aimed to evaluate the association between the timing of advanced life support (ALS) (i.e., endotracheal intubation [ETI] or adrenaline administration) for OHCA at home and prognosis. METHOD: This retrospective cohort study used data from the Japan Utstein Registry and emergency transport data collected from patients who underwent pre-hospital ETI (n = 6806) and received adrenaline (n = 22,636) between 2016 and 2019. The timing of ETI or adrenaline administration was determined as "on the scene" or "in the ambulance." Multiple logistic regression analysis was used to estimate the association among the timing of ALS implementation, pre-hospital return of spontaneous circulation (ROSC), and survival at 1 month. RESULT: ETI on the scene was significantly positively associated with pre-hospital ROSC (adjusted odds ratio [AOR], 1.81; 95% confidence interval [CI], 1.57-2.09) and survival at 1 month (AOR, 1.81; 95% CI, 1.47-2.23). Adrenaline administration on the scene was significantly positively associated with pre-hospital ROSC (AOR, 2.51; 95% CI, 2.33-2.70) and survival at 1 month (AOR, 2.13; 95% CI, 1.89-2.40). CONCLUSION: Our analysis suggests performing ALS on the scene was associated with pre-hospital ROSC and survival at 1 month. Further efforts are needed to increase the rate of ALS implementation on the scene by emergency life-saving technicians.

BACKGROUND: The predictive value of the respiratory rateoxygenation (ROX) index for a high-flow nasal cannula (HFNC) in patients with COVID-19 with acute hypoxemic respiratory failure (AHRF) may differ from patients without COVID-19 with AHRF, but these patients have not yet been compared. We compared the diagnostic accuracy of the ROX index for HFNC failure in patients with AHRF with and without COVID-19 during acute emergency department (ED) visits. METHODS: We performed a retrospective analysis of patients with AHRF treated with an HFNC in an ED between October 2020 and April 2022. The ROX index was calculated at 1, 2, 4, 6, 12, and 24 h after HFNC placement. The primary outcome was the failure of the HFNC, which was defined as the need for subsequent intubation or death within 72 h. A receiver operating characteristic (ROC) curve was used to evaluate discriminative power of the ROX index for HFNC failure. RESULTS: Among 448 patients with AHRF treated with an HFNC in an ED, 78 (17.4%) patients were confirmed to have COVID-19. There was no significant difference in the HFNC failure rates between the non-COVID-19 and COVID-19 groups (29.5% vs. 33.3%, p = 0.498). The median ROX index was higher in the non-COVID-19 group than in the COVID-19 group at all time points. The prognostic power of the ROX index for HFNC failure as evaluated by the area under the ROC curve was generally higher in the COVID-19 group (0.73-0.83) than the non-COVID-19 group (0.62-0.75). The timing of the highest prognostic value of the ROX index for HFNC failure was at 4 h for the non-COVID-19 group, whereas in the COVID-19 group, its performance remained consistent from 1 h to 6 h. The optimal cutoff values were 6.48 and 5.79 for the non-COVID-19 and COVID-19 groups, respectively. CONCLUSIONS: The ROX index had an acceptable discriminative power for predicting HFNC failure in patients with AHRF with and without COVID-19 in the ED. However, the higher ROX index thresholds than those in previous publications involving intensive care unit (ICU) patients suggest the need for careful monitoring and establishment of a new threshold for patients admitted outside the ICU.

BACKGROUND: This study aimed to investigate the effect of esketamine on the dose-effect relationship between remifentanil and the cardiovascular response to endotracheal intubation during target-controlled infusion (TCI) of propofol. METHODS: Patients underwent elective gynecological laparoscopic surgery under general anesthesia with endotracheal intubation, aged 18-65 years, American Society of Anesthesiologists class I or II, 18 kg/m2 ≤ body mass index ≤ 30 kg/m2, were randomly divided into the control (group C) and esketamine groups (group E). Before anesthesia induction, group E received an intravenous injection of 0.3 mg/kg of esketamine, while group C received an equal dose of physiological saline. TCI of propofol to the effect-site concentration (EC) of 3.0 µg/mL, and then TCI of remifentanil to the effect room and intravenous injection of rocuronium 0.6 mg/kg after MOAA/S was 0. Endotracheal intubation was performed after 2 min. Dixon's modified sequential method was used, and the initial EC of remifentanil was 3.0 ng/mL. The EC of remifentanil was determined according to the intubation response of the previous patient, with an adjacent concentration gradient of 0.3 ng/mL. The EC50 and EC95 values and their 95% confidence intervals (CIs) were determined using probit regression analysis. RESULTS: The EC50 for cardiovascular response inhibition to endotracheal intubation using remifentanil was 3.91 ng/mL (95% CI: 3.59-4.33 ng/mL) and EC95 was 4.66 ng/mL (95% CI: 4.27-6.23 ng/mL) with TCI of propofol 3.0 µg/mL. After intravenous administration of 0.3 mg/kg of esketamine, the EC50 of remifentanil was 3.56 ng/mL (95% CI: 3.22-3.99 ng/mL) and EC95 was 4.31 ng/mL (95% CI: 3.91-5.88 ng/mL). CONCLUSIONS: Combined with TCI of propofol 3.0 µg/mL for anesthesia induction, esketamine significantly reduced the EC50 and EC95 of remifentanil to inhibit the cardiovascular response to endotracheal intubation. TRIAL REGISTRATION: The trial was registered in the Chinese Clinical Trials Registry ( www.chictr.org.cn ; registration number: ChiCTR2200064932; date of registration:24/10/2022).

BACKGROUND: Post-operative sore throat (POST) has an incidence ranging from 21 to 80%. To prevent the development of POST, several pharmacological measures have been tried. Aim of this study was to compare the efficacy of preoperative zinc, magnesium and budesonide gargles in reducing the incidence and severity of POST in patients who underwent endotracheal intubation for elective surgeries. METHODS: We conducted a prospective, randomized, double-blind, controlled equivalence trial in 180 patients admitted for elective surgical procedures under general anaesthesia. Patients were randomised into three groups; group Z received 40 mg Zinc, group M received 250 mg Magnesium Sulphate and group B received 200 µg Budesonide in the form of 30 ml tasteless and colourless gargle solutions. Sore throat assessment and haemodynamic recording was done postoperatively at immediate recovery (0 h) and 2, 4, 6, 8, 12 and 24 h post-operatively. POST was graded on a four-point scale (0-3). RESULTS: POST score was comparable at all recorded time points i.e. 0,2,4,6,8,12 and 24 h. Maximum incidence was seen at 8 h in group B (33.3%) and the minimum incidence was at 24 h in group Z (10%) (p > 0.05). It was found that the incidence of POST was more in the surgeries lasting longer than 2 h in all groups. This difference was found to be statistically significant in Groups M and B. The incidence of POST was found to be comparable between laparoscopic and open procedures. CONCLUSION: Magnesium, zinc and budesonide have an equivocal effect in the prevention of POST at different time points. The incidence of sore throat increases significantly in surgeries lasting more than two hours if magnesium or budesonide have been used as premedicant. Duration of surgery is an independent predictor for POST. TRIAL REGISTRATION: CTRI/2021/05/033741 Date-24/05/2021(Clinical Trial Registry of India).

BACKGROUND: Endotracheal intubation is challenging during cardiopulmonary resuscitation, and video laryngoscopy has showed benefits for this procedure. The aim of this study was to compare the effectiveness of various intubation approaches, including the bougie first, preloaded bougie, endotracheal tube (ETT) with stylet, and ETT without stylet, on first-attempt success using video laryngoscopy during chest compression. METHODS: This was a randomized crossover trial conducted in a general tertiary teaching hospital. We included anesthesia residents in postgraduate year one to three who passed the screening test. Each resident performed intubation with video laryngoscopy using the four approaches in a randomized sequence on an adult manikin during continuous chest compression. The primary outcome was the first-attempt success defined as starting ventilation within a one minute. RESULTS: A total of 260 endotracheal intubations conducted by 65 residents were randomized and analyzed with 65 procedures in each group. First-attempt success occurred in 64 (98.5%), 57 (87.7%), 56 (86.2%), and 46 (70.8%) intubations in the bougie-first, preloaded bougie, ETT with stylet, and ETT without stylet approaches, respectively. The bougie-first approach had a significantly higher possibility of first-attempt success than the preloaded bougie approach [risk ratio (RR) 8.00, 95% confidence interval (CI) 1.03 to 62.16, P = 0.047], the ETT with stylet approach (RR 9.00, 95% CI 1.17 to 69.02, P = 0.035), and the ETT without stylet approach (RR 19.00, 95% CI 2.62 to 137.79, P = 0.004) in the generalized estimating equation logistic model accounting for clustering of intubations operated by the same resident. In addition, the bougie first approach did not result in prolonged intubation or increased self-reported difficulty among the study participants. CONCLUSIONS: The bougie first approach with video laryngoscopy had the highest possibility of first-attempt success during chest compression. These results helped inform the intubation approach during CPR. However, further studies in an actual clinical environment are warranted to validate these findings.

INTRODUCTION: Neonates in intensive care units often require endotracheal intubation and mechanical ventilation. During this intubation procedure, a stylet is frequently used along with an endotracheal tube. Despite the widespread use of a stylet, it is still not known whether its use increases the intubation success rate. This study examined the association between stylet use and the intubation success rate in surgical neonates. METHODOLOGY: This single-center study was conducted between December 2021 and December 2022 in the Neonatal surgical intensive care unit of a tertiary care center in Northern India. Infants were randomized to have the endotracheal intubation procedure performed using either an endotracheal tube alone or with a stylet. The primary outcome of the study was to assess the successful first-attempt neonatal endotracheal intubation rate with and without using a stylet. Apart from the rate of successful intubation, the duration of the intubation and complications during the intubation procedures as measured by bradycardia, desaturation episodes, and local trauma were also recorded. Both groups were thus compared on above mentioned outcomes. RESULTS: The total number of neonates enrolled were 200, and the overall success rate (81% in the stylet group vs. 73% in the non-stylet group) was not statistically significant. Intubation time was however less, when stylet was used (16.2 ± 4.3 vs. 17.5 ± 5.0 s, p = .046). When the endotracheal tube size was 3 or less, the success rate was substantially higher in the stylet group (80%) than the non-stylet group (63%), p = .03. No statistical difference was recorded for bleeding and local trauma, though the esophageal intubation rate was higher when intubation was attempted without the stylet. CONCLUSION: Endotracheal intubation using a stylet did not significantly improve the success rate of the procedure, however, intubation time significantly varied between groups and in different conditions. The rigidity and curvature provided by the stylet may facilitate the process of intubation when smaller caliber endotracheal tubes are used.

BACKGROUND: Prediction of serious outcomes among patients with physiological instability is crucial in airway management. In this study, we aim to develop a score to predict serious outcomes following intubation in critically ill adults with physiological instability by using clinical and laboratory parameters collected prior to intubation. METHOD: This single-center analytical cross-sectional study was conducted in the Emergency Department from 2016 to 2020. The airway score was derived using the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis (TRIPOD) methodology. To gauge model's performance, the train-test split technique was utilized. The discrete random number generation approach was used to divide the dataset into two groups: development (training) and validation (testing). The validation dataset's instances were used to calculate the final score, and its validity was measured using ROC analysis and area under the curve (AUC). By computing the Youden's J statistic using the metrics sensitivity, specificity, positive predictive value, and negative predictive value, the discriminating factor of the additive score was determined. RESULTS: The mean age of the 1021 patients who needed endotracheal intubations was 52.2 years (± 17.5), and 632 (62%) of them were male. In the development dataset, there were 527 (64.9%) physiologically difficult airways, 298 (36.7%) post-intubation hypotension, 124 (12%) cardiac arrest, 347 (42.7%) shock index > 0.9, and 456 [56.2%] instances of pH < 7.3. On the contrary, in the validation dataset, there were 143 (68.4%) physiologically difficult airways, 33 (15.8%) post-intubation hypotension, 41 (19.6%) cardiac arrest, 87 (41.6%) shock index > 0.9, and 121 (57.9%) had pH < 7.3, respectively. There were 12 variables in the difficult airway physiological score (DAPS), and a DAPS of 9 had an area under the curve of 0.857. The accuracy of DAPS was 77%, the sensitivity was 74%, the specificity was 83.3%, and the positive predictive value was 91%. CONCLUSION: DAPS demonstrated strong discriminating ability for anticipating physiologically challenging airways. The proposed model may be helpful in the clinical setting for screening patients who are at high risk of deterioration.

Introduction: Preanesthesia teleconsultation helps reduce availability constraints as well as direct and indirect expenses. The TELECAM trial was performed to assess the quality of preanesthesia teleconsultation in terms of clinical parameters evaluation, feasibility, patient satisfaction and preoperative anxiety, and anesthesiologist satisfaction. Methods: TELECAM was an investigator-initiated, prospective, single-center, randomized, controlled, parallel group, evaluator-blinded, open-label study. Patients with a scheduled ambulatory surgery (orthopedic or hand surgery) were randomized into the in-person preanesthesia consultation group or the preanesthesia teleconsultation (conducted at the patient's home or workplace) group. The quality of the teleconsultation was evaluated through agreement on intubation difficulty, predictable mask ventilation difficulty, and American Society of Anesthesiologists (ASA) scores between the preanesthesia consultation and the preanesthesia in-person visit. Results: A total of 241 patients were included, and 208 were considered in the analyses. The feasibility of teleconsultation was high, with a feasibility ratio of 87.5%. The quality of the preanesthesia consultation regarding the evaluation of predictable intubation, mask ventilation difficulties, and ASA score, did not differ between the two groups (p = 0.23, 0.29, and 0.06, respectively). The preoperative satisfaction was higher for patients who had a preanesthesia teleconsultation (p = 0.04). Patients' preoperative anxiety did not differ between the two groups (p = 0.90). The median satisfaction of the anesthesiologists who performed the teleconsultation reached a maximum of 10 (IQR: 8.0; 10.0). Conclusion: This study showed positive results for the quality of preanesthesia teleconsultation on the evaluation of clinical parameters, with high feasibility and satisfaction of the patients and anesthesiologists. The trial was registered in ClinicalTrials (NCT03470896).

BACKGROUND: There are no published minute-by-minute physiological assessment data for endotracheal intubation (ETT) performed in the intensive care unit (ICU). The majority of physiological data is available from Europe and North America where etomidate is the induction agent administered most commonly. AIMS: The aim of this study was to describe the feasibility of obtaining minute-by-minute physiological and medication data surrounding ETT in an Australian tertiary ICU and to assess its associated outcomes. METHODS: We performed a single-centre feasibility observational study. We obtained minute-by-minute data on physiological variables and medications for 15 min before and 30 min after ETT. We assessed feasibility as enrolled to screened patient ratio and completeness of data collection in enrolled patients. Severe hypotension (systolic blood pressure < 65 mmHg) and severe hypoxaemia (pulse oximetry saturation < 80%) were the secondary clinical outcomes. RESULTS: We screened 43 patients and studied 30 patients. The median age was 58.5 (interquartile range: 49-70) years, and 18 (60%) were male. Near-complete (97%) physiological and medication data were obtained in all patients at all times. Overall, 15 (50%) ETTs occurred after hours (17:30-08:00) and 90% were by video laryngoscopy with a 90% first-pass success rate. Prophylactic vasopressors were used in 50% of ETTs. Fentanyl was used in all except one ETT at a median dose of 2.5 mcg/kg. Propofol (63%) or midazolam (50%) were used as adjuncts at low dose. Rocuronium was used in all but one patient. There were no episodes of severe hypotension and only one episode of short-lived severe hypoxaemia. CONCLUSION: Minute-by-minute recording of ETT-associated physiological changes in the ICU was feasible but only fully available in two-thirds of the screened patients. ETT was based on fentanyl induction, low-dose adjunctive sedation, and frequent prophylactic vasopressor therapy and was associated with no severe hypotension and a single short-lived episode of severe hypoxaemia.
RESUMO
BACKGROUND: Thirst is a common symptom among patients with endotracheal intubation in the intensive care unit (ICU), with an estimated prevalence of 88%. PURPOSE: This study was designed to compare the effectiveness of cold saline spray and cold water spray in alleviating thirst, and to explore the maintenance and sustained effects of both groups in relieving thirst among patients with endotracheal intubation in the ICU. METHODS: Patients with indwelling tracheal tubes in the medical ICU were recruited from one medical center in northern Taiwan and randomly assigned to either the cold saline (n = 18) or cold water (n = 18) group. The cold saline group received three rounds of cold saline spray at a temperature of 2°C - 8°C. Each round consisted of 10 sprays directed toward each of the four surfaces of the oral cavity followed by a 5-minute wait period. This process was repeated three times, with 30-minute intervals between interventions. The cold water group received the same intervention steps using a cold water spray at 2°C - 8°C. Thirst intensity was measured using a numeric rating scale before and after each of the three interventions in both groups. Demographic and relevant physiological data were collected on the participants by reviewing their medical records. RESULTS: Both of the interventions were found to effectively alleviate thirst intensity, with no significant difference between the two groups in terms of thirst intensity reduction after each intervention detected. Only the cold water spray had a maintenance effect, while the two groups had a continuous sustained effect in alleviating thirst intensity. CONCLUSIONS: Both of the interventions effectively alleviated thirst, and the cold water spray had both maintenance and sustained effects in alleviating thirst intensity. Based on the results, the cold water spray method may be considered as the priority treatment for thirst alleviation by healthcare providers in the clinical management of patients with tracheal intubation.

According to current European Resuscitation Council guidelines, priorities in advanced life support in adult are chest compression with minimal interruption and early defibrillation. Endotracheal intubation is still considered the gold standard in airway management, but guidelines suggest that securing the airway be incremental, ranging from basic techniques to more complex ones. Doctors who work in pre-hospital emergency medicine teams (EMT) in Croatia usually lack sufficient education and expertise. The aim of this study was to determine whether there was a significant difference in recovery of spontaneous circulation during cardiopulmonary resuscitation (CPR) in out-of-hospital setting depending on the EMT airway management technique of choice. This retrospective analysis included data collected during a 10-year period at the Krapina-Zagorje County Emergency Medicine Institute on all patients with CPR performed by EMTs 20 minutes from initial emergency call. The airway management groups included oropharyngeal tube, i-gel supraglottic device, and endotracheal tube. There were 968 patients, mean age 70. In 74.61% of patients, the cause of arrest was of cardiac etiology. Our study did not find a statistically significant in difference of CPR success among the three groups analyzed according to the airway management technique of choice (p=0.74, χ2-test).

The aim of this paper is to gather and evaluate available literature about using videolaryngoscopy as a training tool for novice learners and compare it to direct laryngoscopy. Search of the available literature was performed using the MEDLINE database, through the PubMed searching tool. The inclusion criteria were that papers had to be original research and participants had to be novices in the field of airway management. The studies also had to pertain to the topic of using videolaryngoscopy as a training tool, therefore all papers that evaluated performance of videolaryngoscopy in clinical applications or did not pertain to using videolaryngoscopy as a training tool were excluded from this review. Five studies were identified that fitted the inclusion criteria, all of which showed a statistically significant difference in first attempt success at endotracheal intubation in favor of videolaryngoscopy when compared to direct laryngoscopy. One of the studies also demonstrated a faster skill acquisition rate when using videolaryngoscopy. The use of videolaryngoscopy in teaching airway management to trainees (emergency medicine residents included) is a viable option and should be encouraged and researched further.

Endotracheal intubation is an airway management procedure commonly performed under general anesthesia. It is linked with postoperative voice changes. The incidence and reasons of hoarseness and vocal cord injury are not very well investigated, especially after short-term anesthesia and intubation in head and neck surgery. The aim of the study is to identify the causes of voice changes after short endotracheal anesthesia in head and neck surgery. The study will include patients scheduled for head and neck surgery under general anesthesia with endotracheal intubation up to 3 hours. There will be 3 groups of patients, as follows: thyroid surgery, non-thyroid surgery, and control group undergoing surgery outside head and neck. Videostroboscopy will be recorded before and after surgery. Further diagnostic workup will include voice status; subjective voice self-analysis; perceptive and objective acoustic voice analysis at 4 time points (preoperatively, postoperative day 2, 2 weeks and 1 month after surgery). Endotracheal intubation is a safe method of airway management although it can temporarily alter a patient's voice quality. It is not known how much of this is the result of anesthesia, general condition of the patient, or surgery. This trial is expected to shed some light on this issue.

BACKGROUND AND AIMS: Maintaining the airway with a cuffed endotracheal tube (ETT) in the trachea remains one of the most essential anaesthesia skills. Many parameters were described to assess the difficulty of intubation in the preoperative period, but none allow the prediction of all difficult intubations. The correct posture of the anaesthesiologist is also an important factor for successful endotracheal intubation. The aim of this study was. This study aimed to compare the impact of two different positions of an anaesthesiologist (sitting vs. standing) at the time of endotracheal intubation. METHODS: One hundred ten American Society of Anaesthesiologists (ASA) Physical Status I/II patients, aged between 17 to 65 years, Mallampati grade I/II, mouth opening 39-70 mm, thyromental distance (TMD) 6-6.5 cm, and sternomental distance (SMD) >13 cm, scheduled for elective laparoscopic cholecystectomy, were recruited. Patients were divided into two groups; Group I consisted of patients who underwent endotracheal intubation by an anaesthesiologist in a sitting posture, while Group II encompassed patients who underwent endotracheal intubation by anaesthesiologists in a standing posture. Assessment parameters include ease of intubation (IDS score), intubation time, intubation success rate, number of attempts, grade of laryngoscopy (Cormack Lehane score, POGO score), and complications like tooth and soft tissue damage. RESULTS: The ease of intubation was higher in group I, 1(0-1), than in group II, 1(1-2) (p = 0.02), and there was a significant difference between the two groups. The Cormack Lehane grade (CL) was I/IIa/IIb/III in 19/23/13/0 in group I and I/IIa/IIb/III in 13/21/18/3 in group II. The first-attempt intubation success rate for groups I and II was 94.54 % and 92.72 % respectively. CONCLUSION: The sitting posture of an anaesthesiologist at the time of laryngoscopy provides a better intubating condition when compared with the standing posture.

RESUMO
STUDY OBJECTIVE: Postoperative sore throat (POST) and hoarseness are common complications of tracheal intubation. This study aims to evaluate the efficacy of flurbiprofen administered through the subglottic port of tracheal tubes to prevent POST after cardiac surgery. DESIGN: Single-center, prospective, randomized, double-blind, placebo-controlled trial. SETTING: Tertiary Care Referral University Hospital (Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome). PATIENTS: Included 71 patients undergoing for elective cardiac surgery. Inclusion criteria were (a) age between 50 and 75 years, (b) NYHA class I or II, (c) surgery for myocardial revascularization or valve repair or replacement under cardiopulmonary bypass. INTERVENTION: Patients were double blind randomized to receive flurbiprofen or saline in the subglottic port of the endotracheal tube (groups F and P). The solution was injected ten minutes after tracheal tube placement, ten minutes after ICU admission and ten minutes before tracheal tube removal. MEASUREMENTS: The primary outcome was to assess the effect of topical flurbiprofen administered through the subglottic port of the tracheal tube to prevent post-operative sore throat (POST). The secondary outcomes were the presence of hoarseness safety and patient's subjective satisfaction with their recovery. We did not report any exploratory outcomes. MAIN RESULTS: We analyzed 68 patients, 34 patients in each group. In group F, two patients complained of POST and hoarseness (5.9%), while all controls did. The two groups significantly differed in the severity scores (VAS and TPS for sore throat and HOAR for hoarseness) at all time points. In group P, patients reported mild to moderate symptoms that significantly improved or disappeared 36 h after tracheal tube removal. According to the multivariable model, hoarseness affected women less than men, in the control group (p = 0.002). None of the patients in either group reported any adverse effects. CONCLUSIONS: Repeated administration of flurbiprofen through the subglottic port of tracheal tubes reduced the incidence of sore throat and hoarseness after cardiac surgery without evidence of complications.

OBJECTIVE: The aim was to design accessible, simple, inexpensive protection for teeth and soft tissues during ETI, compare damage occurrence with and without protection, and investigate post-ETI orofacial pain symptoms. MATERIALS AND METHODS: The selection procedure for adequate protection was carried out after which a reduced elastomer mouthguard was selected. Fifty patients were divided into 2 groups. In the first group, ETI was carried out using a mouthguard, while in the second group it was performed without it. The mouthguard was fabricated by anesthesiologists. After the ETI procedure, the patients and anesthesiologists were asked to complete a survey. RESULTS: No difference in intubation severity and time required for intubation between the two groups was present. Seven patients from the non-mouthguard group suffered injuries during the ETI procedure. No injuries were present in the mouthguard group. In 92% of cases anesthesiologists agreed that mouthguards should be used during ETI. However, most of them (96% of cases) agree that the mouthguard should be used only when there is an increased risk of tooth loss and/or tooth damage. There was a significant ETI effect on the emergence of new orofacial pain cases. CONCLUSION: The mouthguard adequately protected dental and soft tissues and did not affect the work of the anesthesiologist. A significantly higher number of patients experiencing temporomandibular joint and masticatory muscles pain after surgery indicates that ETI might be a risk factor for orofacial pain.
RESUMO
The use of video laryngoscopes has enhanced the visualization of the vocal cords, thereby improving the accessibility of tracheal intubation. Employing artificial intelligence (AI) to recognize images obtained through video laryngoscopy, particularly when marking the epiglottis and vocal cords, may elucidate anatomical structures and enhance anatomical comprehension of anatomy. This study investigates the ability of an AI model to accurately identify the glottis in video laryngoscope images captured from a manikin. Tracheal intubation was conducted on a manikin using a bronchoscope with recording capabilities, and image data of the glottis was gathered for creating an AI model. Data preprocessing and annotation of the vocal cords, epiglottis, and glottis were performed, and human annotation of the vocal cords, epiglottis, and glottis was carried out. Based on the AI's determinations, anatomical structures were color-coded for identification. The recognition accuracy of the epiglottis and vocal cords recognized by the AI model was 0.9516, which was over 95%. The AI successfully marked the glottis, epiglottis, and vocal cords during the tracheal intubation process. These markings significantly aided in the visual identification of the respective structures with an accuracy of more than 95%. The AI demonstrated the ability to recognize the epiglottis, vocal cords, and glottis using an image recognition model of a manikin.
