Background: There is debate on the impact of inhalational esthetic agents on transcranial motor evoked potentials (TcMEPs) during intraoperative neuromonitoring. Current guidelines advise their avoidance, which contrasts with common clinical practice., Methods: This retrospective cohort study of 150 consecutive cervical spine surgeries at a single institution compared stimulation voltages and TcMEP amplitudes in patients who did and did not receive sevoflurane as part of a balanced anesthetic technique. Patients were divided into 3 groups stratified by the presence or absence of increased signal intensity within the cervical spinal cord on T2-weighted magnetic resonance imaging (indicative or myelopathy/spinal cord injury [SCI]) and sevoflurane use., Results: Patients with no magnetic resonance imaging evidence of myelopathy/SCI that received sevoflurane (n=80) had the lowest stimulation voltages and largest TcMEP amplitude responses in the lower extremities compared with those with no magnetic resonance imaging evidence of myelopathy/SCI (n=30). In patients with evidence of myelopathy/SCI who did not receive sevoflurane (n=19), lower extremity TcMEP amplitudes were similar to patients with a myelopathy/SCI that received sevoflurane. Six of these 19 patients had initial low-dose sevoflurane discontinued because of concerns of low/absent baseline TcMEP amplitudes., Conclusions: Balanced anesthesia with 0.5 MAC sevoflurane in patients with and without radiological evidence of myelopathy/SCI allows reliable TcMEP monitoring. However, in communication with surgical and neuromonitoring teams, it may be advisable in a subset of patients to avoid or discontinue sevoflurane in favor of a propofol/opioid-based anesthetic to ensure adequate and reproducible TcMEPs., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2023 Wolters Kluwer Health, Inc.

Techniques for facilitating nasal intubation and reducing associated airway trauma are well documented in the literature. This case series describes an additional technique that combines the use of the video laryngoscope and fiberoptic bronchoscope for intubation. Rather than first starting with the fiberoptic bronchoscope, an endotracheal tube is passed through the nasopharynx and lined up with the glottis using video laryngoscopy. Subsequently, the fiberoptic bronchoscope is used only to guide the endotracheal tube through the glottis. The two perspectives simultaneously provide enhanced guidance to the operator, which can, in turn, reduce the burden of fiberoptic navigation through blood, secretions, and/or altered airway anatomy. Additionally, our report demonstrates that this procedure can be used as a rescue measure when Magill forceps are unsuccessful., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Nedrud et al.)

Awake intubation is frequently described in the literature as the preferred method for securing the airway in adult patients with epiglottitis, whereas children with epiglottitis are usually intubated following an inhalational induction. However, if topicalization is difficult due to the presence of an abscess or an uncooperative patient, an inhalational induction may still be a reasonable approach in the adult patient. In a review of the literature, only one recent case report had been found describing an inhalational induction with video laryngoscopy. However, this attempt was unsuccessful, mandating the need for a surgical airway. Our case report describes a successful inhalational induction and video laryngoscope intubation without the use of a paralytic agent in an adult patient with an epiglottic abscess and moderate airway stenosis., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Manatpon et al.)
