Randomized Controlled Trial Comparative StudyMcGrath MAC Videolaryngoscope Versus Optiscope Video Stylet for Tracheal Intubation in Patients With Manual Inline Cervical Stabilization: A Randomized Trial.
Manual inline stabilization of the head and neck is a recommended maneuver for tracheal intubation in patients with a suspected cervical injury. However, because applying this maneuver inevitably restricts neck flexion and head extension, indirect intubating devices such as a videolaryngoscope or a video stylet could be required for successful tracheal intubation. In this study, we compared the clinical performance of the McGrath MAC videolaryngoscope versus the Optiscope video stylet in patients with manual inline cervical stabilization during tracheal intubation. ⋯ The McGrath MAC videolaryngoscope showed a higher first-attempt success rate for tracheal intubation and a shorter intubation time than the Optiscope video stylet in cervical spine patients with manual inline stabilization during tracheal intubation. These results suggest that the McGrath MAC videolaryngoscope may be a better option for tracheal intubation in such patients.

Multicenter StudyAwake Volunteer Pain Scores During Neuromuscular Monitoring.
There is a need for easy to use, reliable neuromuscular monitors (NMMs). This multicenter, prospective, unblinded study compared the discomfort associated with neurostimulation in unmedicated healthy volunteers when using the new electromyography (EMG)-based TetraGraph and acceleromyography (AMG)-based TOF-Watch NMMs. The secondary aim was to compare the repeatability of the train-of-four (TOF) ratios (TOFRs) obtained with the 2 devices. ⋯ Despite the different size and design of the stimulating electrodes, the 2 NMMs caused the same level of discomfort in unmedicated healthy volunteers.

Observational StudyReal-Time Ultrasound Improves Accuracy of Caudal Block in Children.
Caudal block, the most common regional anesthetic in children, is predominantly performed using palpation to determine placement. The efficacy of the palpation technique is unknown with respect to block success. While ultrasound has been suggested for use during caudal block, its use is infrequent. ⋯ Real-time ultrasound visualization of local anesthetic injection provides reliable and immediate confirmation during caudal block in children.
