OBJECTIVE: Shock, cardiovascular problems, and respiratory failure constitute the main causes of death in patients cared in medical emergency rooms. Patients commonly require orotracheal intubation (OTI), a fact that has been intensified by diseases that generate important and fatal hemodynamic and respiratory problems in the affected patient.
METHODS: Although etomidate (ETO) is a highly used anesthetic for OTI, its use remains controversial in several scenarios. Some studies refer to an increase in mortality with its use in critically patients, while others do not refer to a difference. Therefore, we evaluated the mortality of patients submitted to OTI in the public hospital of a public federal university, with the use of ETO and other sedative-hypnotic drugs used in the induction of the performance of OTI, with the in-hospital mortality of patients cared in hospital.
RESULTS: The results demonstrate that the use of ETO as a hypnotic for OTI in the emergency room is not associated with a significant difference in morbidity or early mortality, within 30 days of hospitalization, compared with other hypnotics.
CONCLUSIONS: There was no difference in mortality between patients intubated in the emergency department who used ETO and those who used non-ETO hypnotic within 72 hours and 30 days.

BACKGROUND: Cytokine release syndrome (CRS) is a common adverse event of chimeric antigen receptor T (CAR-T) cell therapy. CRS is generally a systemic inflammatory reaction, but in rare cases, it can occur in specific body areas and is referred to as \"local CRS (L-CRS).\" A case of laryngeal edema due to L-CRS that required tracheal intubation because of the lack of response to tocilizumab (TCZ) and dexamethasone (DEX) is reported.
METHODS: A 67-year-old woman with relapsed transformed follicular lymphoma was treated with CAR-T cell therapy. Although she had been given TCZ and DEX for CRS, neck swelling appeared on day 4 after infusion.
METHODS: Laryngoscopy showed severe laryngeal edema, which was presumed to be due to L-CRS, since there were no other apparent triggers based on history, physical examination, and computed tomography.
METHODS: Tracheal intubation was performed because of the risk of upper airway obstruction. Ultimately, 4 doses of tocilizumab (8 mg/kg) and 6 doses of dexamethasone (10 mg/body) were required to improve the L-CRS.
RESULTS: On day 7, laryngeal edema improved, and the patient could be extubated.
CONCLUSIONS: The lessons from this case are, first, that CAR-T cell therapy may induce laryngeal edema in L-CRS. Second, TCZ alone may be ineffective in cervical L-CRS. Third, TCZ, as well as DEX, may be inadequate. In such cases, we should recognize L-CRS and manage it early because it may eventually progress to laryngeal edema that requires securing the airway.

BACKGROUND: The primary objective of anesthesiologists during the induction of anaesthesia is to mitigate the operative stress response resulting from endotracheal intubation. In this prospective, randomized controlled trial, our aim was to assess the feasibility and efficacy of employing Index of Consciousness (IoC, IoC1 and IoC2) monitoring in predicting and mitigating circulatory stress induced by endotracheal intubation for laparoscopic cholecystectomy patients under general anesthesia (GA).
METHODS: We enrolled one hundred and twenty patients scheduled for laparoscopic cholecystectomy under GA and randomly allocated them to two groups: IoC monitoring guidance (Group T, n = 60) and bispectral index (BIS) monitoring guidance (Group C, n = 60). The primary endpoints included the heart rate (HR) and mean arterial pressure (MAP) of the patients, as well as the rate of change (ROC) at specific time points during the endotracheal intubation period. Secondary outcomes encompassed the systemic vascular resistance index (SVRI), cardiac output index (CI), stroke volume index (SVI), ROC at specific time points, the incidence of adverse events (AEs), and the induction dosage of remifentanil and propofol during the endotracheal intubation period in both groups.
RESULTS: The mean (SD) HR at 1 min after intubation under IoC monitoring guidance was significantly lower than that under BIS monitoring guidance (76 (16) beats/min vs. 82 (16) beats/min, P = 0.049, respectively). Similarly, the mean (SD) MAP at 1 min after intubation under IoC monitoring guidance was lower than that under BIS monitoring guidance (90 (20) mmHg vs. 98 (19) mmHg, P = 0.031, respectively). At each time point from 1 to 5 min after intubation, the number of cases with HR ROC of less than 10% in Group T was significantly higher than in Group C (P < 0.05). Furthermore, between 1 and 3 min and at 5 min post-intubation, the number of cases with HR ROC between 20 to 30% or 40% in Group T was significantly lower than that in Group C (P < 0.05). At 1 min post-intubation, the number of cases with MAP ROC of less than 10% in Group T was significantly higher than that in Group C (P < 0.05), and the number of cases with MAP ROC between 10 to 20% in Group T was significantly lower than that in Group C (P < 0.01). Patients in Group T exhibited superior hemodynamic stability during the peri-endotracheal intubation period compared to those in Group C. There were no significant differences in the frequencies of AEs between the two groups (P > 0.05).
CONCLUSIONS: This promising monitoring technique has the potential to predict the circulatory stress response, thereby reducing the incidence of adverse reactions during the peri-endotracheal intubation period. This technology holds promise for optimizing anesthesia management.

Although prehospital emergency anesthesia (PHEA), with a specific focus on intubation attempts, is frequently studied in prehospital emergency care, there is a gap in the knowledge on aspects related to adherence to PHEA guidelines. This study investigates adherence to the \"Guidelines for Prehospital Emergency Anesthesia in Adults\" with regard to the induction of PHEA, including the decision making, rapid sequence induction, preoxygenation, standard monitoring, intubation attempts, adverse events, and administration of appropriate medications and their side effects. This retrospective study examined PHEA interventions from 01/01/2020 to 12/31/2021 in the city of Aachen, Germany. The inclusion criteria were adult patients who met the indication criteria for the PHEA. Data were obtained from emergency medical protocols. A total of 127 patients were included in this study. All the patients met the PHEA indication criteria. Despite having a valid indication, 29 patients did not receive the PHEA. 98 patients were endotracheally intubated. For these patients, monitoring had conformed to the guidelines. The medications were used according to the guidelines. A significant increase in oxygen saturation was reported after anesthesia induction (p < 0.001). The patients were successfully intubated endotracheally on the third attempt. Guideline adherence was maintained in terms of execution of PHEA, rapid sequence induction, preoxygenation, monitoring, selection, and administration of relevant medications. Emergency physicians demonstrated the capacity to effectively respond to cardiorespiratory events. Further investigations are needed on the group of patients who did not receive PHEA despite meeting the criteria. The underlying causes of decision making in these cases need to be evaluated in the future.

BACKGROUND: Compared with the operating room, tracheal intubations in the intensive care unit (ICU) are associated with worsened glottic view, decreased first-time success rate and increase in the technical difficulty of intubation and incidence of complications. Videolaryngoscopes (VLs) have been proposed to improve airway management, and while recent studies have confirmed that VLs improve intubation conditions in this patient population, there remains a lack of clarity regarding the selection between a standard Macintosh blade or a hyperangulated one, to determine which yields the best outcomes. The purpose of this study was to compare successful intubation on the first attempt with the Macintosh VL versus the hyperangulated VL during tracheal intubation in ICU patients. We hypothesise that tracheal intubation using the hyperangulated VL will improve the frequency of successful intubation on the first attempt.
METHODS: The INtubation VIdeolaryngoscopy BLADE-ICU trial is a prospective, multicentre, open-label, interventional, randomised, controlled superiority study conducted in 29 ICUs in Spain. Patients will be randomly assigned in a 1:1 ratio to undergo intubation using a Macintosh VL (control group) or a hyperangulated VL (experimental group) for the first intubation attempt. The primary outcome is successful intubation on the first attempt. The secondary outcomes include the time to intubation, attempts for successful intubation, laryngoscopic vision assessed with the modified Cormack-Lehane scale, the need for adjuvant airway devices for intubation, difficulty assessed by the anaesthesiologist and complications during tracheal intubation. Enrolment began on 1 May 2024 and is expected to be completed in 2025.
BACKGROUND: The study protocol was approved on 29 February 2024, by the Ethics Committee of Galicia (CEImG, code No. 2024-031).The results will be submitted for publication in a peer-reviewed journal.

Emergency front-of-neck access refers to all techniques that deliver oxygen into the airway lumen through the anterior neck structures and encompasses access both through the cricothyroid membrane and the tracheal wall. There has yet to be a universal agreement regarding the preferred technique. A surgical incision is currently the most common approach in prehospital and in-hospital care. This review intends to review and summarize the existing clinical, basic science, and societal guidelines for eFONA.

UNASSIGNED: Supraglottic airways have been utilized as an alternative to facemask ventilation and endotracheal intubation and thus have been essential to airway management since their introduction in the late 1980s. This chapter describes basic considerations in their use and an update on current clinical practice, with an emphasis on safe management. The devices have evolved to meet today\'s clinical airway challenges, and they provide benefits for patients and practitioners.
