Randomized Controlled Trial Comparative StudyUltrasound-Guided Infraclavicular Brachial Plexus Block: Prospective Randomized Comparison of the Lateral Sagittal and Costoclavicular Approach.
It has recently been proposed that an infraclavicular brachial plexus block (BPB) at the costoclavicular (CC) space may overcome some of the limitations of the lateral sagittal (LS) approach. In this study, we hypothesized that the CC approach will produce faster onset of sensory blockade of the 4 major terminal nerves of the brachial plexus than the LS approach. ⋯ This study was registered at the Centre for Clinical Trials of The Chinese University of Hong Kong, identifier CUHK_CCT00389.

Improving Clinical Proficiency Using a 3-Dimensionally Printed and Patient-Specific Thoracic Spine Model as a Haptic Task Trainer.
Advanced haptic simulators for neuraxial training are expensive, have a finite life, and are not patient specific. We sought to demonstrate the feasibility of developing a custom-made, low-cost, 3-dimensionally printed thoracic spine simulator model from patient computed tomographic scan data. This study assessed the model's practicality, efficiency as a teaching tool, and the transfer of skill set into patient care. ⋯ By using patient-specific, 3-dimensionally printed, thoracic spine models, we demonstrated a significant improvement in clinical proficiency as compared with traditional teaching models.

Randomized Controlled Trial Comparative StudyComparison of the ED50 and ED95 of Intrathecal Bupivacaine in Parturients Undergoing Cesarean Delivery With or Without Prophylactic Phenylephrine Infusion: A Prospective, Double-Blind Study.
While prophylactic phenylephrine infusions during cesarean delivery are often used to counteract the sympathectomy associated with spinal anesthesia, their use has been associated with decreased rostral spread of local anesthetic. The purpose of this study was to determine the median effective dose (ED50) and 95% effective dose (ED95) of intrathecal hyperbaric bupivacaine for cesarean delivery in the presence and absence of prophylactic phenylephrine infusion. ⋯ This study was registered at the Chinese Clinical Trial Registry, identifier ChiCTR-TRC-16008938.

Randomized Controlled Trial Comparative StudyUltrasound-Guided Selective Versus Conventional Block of the Medial Brachial Cutaneous and the Intercostobrachial Nerves: A Randomized Clinical Trial.
For superficial surgery of anteromedial and posteromedial surfaces of the upper arm, the medial brachial cutaneous nerve (MBCN) and the intercostobrachial nerve (ICBN) must be selectively blocked, in addition to an axillary brachial plexus block. We compared efficacy of ultrasound-guided (USG) versus conventional block of the MBCN and the ICBN. ⋯ This study was registered at ClinicalTrials.gov, identifier NCT02940847.
