Multicenter Study Observational Study
Remifentanil and worse patient-reported outcomes regarding postoperative pain management after thyroidectomy.
Intraoperative remifentanil has been associated with postoperative hyperalgesia, higher visual analogic pain scores, and increased postoperative morphine consumption. However, this has not been investigated from patient's perspective by using a patient-reported outcomes (PROs) approach with a validated questionnaire. ⋯ Our study suggests that remifentanil-based anesthesia is associated with worse pain-related PROs in patients undergoing thyroidectomy despite more frequent intraoperative analgesic administration. This study adds further evidence to the growing literature about opioid- and remifentanil-induced hyperalgesia.

Comparative Study Controlled Clinical Trial
Prone position results in enhanced pressor response to ephedrine compared with supine position during general anesthesia.
To elucidate and compare the pressor response to ephedrine in the prone or supine position during general anesthesia (GA). ⋯ Compared to the supine position, the prone position could augment the pressor response to IV ephedrine during GA. Further studies are recommended to identify its association with other confounding factors such as surgery type or duration, patient history of cardiovascular disease, or patient hydration status.

Randomized Controlled Trial Comparative Study
Comparison of the C-MAC video laryngoscope to a flexible fiberoptic scope for intubation with cervical spine immobilization.
To compare the C-MAC video laryngoscope to the standard flexible fiberoptic scope (FFS) with an eye piece (but without a camera or a video screen) for intubation of patients undergoing cervical spine surgery with manual inline stabilization. The primary end point was the time to achieve successful tracheal intubation. Secondary end points included glottic view at intubation and number of intubation attempts. ⋯ The C-MAC may offer an advantage over the FFS with respect to the time required to obtain glottic view and successful placement of the tracheal tube in patients requiring cervical spine immobilization.

Multicenter Study
Major complications of regional anesthesia in 11 teaching hospitals of China: a prospective survey of 106,569 cases.
To determine the incidence of major complications in patients undergoing regional anesthesia (RA) in China. ⋯ This large, multicenter, prospective survey revealed the incidence of major complications after RA in China's hospitals. Although severe complication like cardiac arrest is rare, it is distressing and challenging. Hence, there is still a room to improve on daily basis to further reduce complications related to RA.

Randomized Controlled Trial
Two methods for teaching basic upper airway sonography.
The purpose of this study was to evaluate and compare hands-on gel phantom versus instructional video teaching methods to improve anesthesia residents and staff members' ability to correctly identify airway structures using ultrasound on a human volunteer. ⋯ Use of either a low cost, airway gel phantom training model for hands-on training or a simple instructional teaching video can be used in a single training session to improve staff anesthesiologist and anesthesia resident knowledge and skills for ultrasound identification of upper airway anatomy.
