T2-weighted Imaging Hyperintensity and Transcranial Motor-evoked Potentials During Cervical Spine Surgery: Effects of Sevoflurane in 150 Consecutive Cases.

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.

Combined Video Laryngoscope and Fiberoptic Nasal Intubation.

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.

Airway Management for an Adult Epiglottic Abscess.

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.

Characteristics and smoking cessation outcomes of patients returning for repeat tobacco dependence treatment.

Previous studies of tobacco dependence treatment have reported very low cessation rates among smokers who relapse and return to make a subsequent formal attempt to quit. This retrospective cohort study examined 1745 patients who attended a tobacco dependence clinic between 2001 and 2005, and the characteristics and outcomes of those who relapsed and returned for repeat treatment. Patients who returned for repeat treatment showed higher markers of nicotine dependence and were more likely to have a history of treatment for mental health problems than patients who attended the clinic for only one treatment episode.
