Randomized Controlled TrialInjection Volume and Anesthetic Effect in Serratus Plane Block.
Serratus plane block is performed for analgesia of the anterior chest wall. However, there has been no study concerning the appropriate volume for this block. This prospective randomized controlled study assesses the dermatomal spread and analgesic effects of serratus plane block. ⋯ UMIN Clinical Trials Registry (identifier UMIN000016549).

ReviewUltrasound-Guided Regional Anesthesia Simulation Training: A Systematic Review.
Ultrasound-guided regional anesthesia (UGRA) has become the criterion standard of regional anesthesia practice. Ultrasound-guided regional anesthesia teaching programs often use simulation, and guidelines have been published to help guide URGA education. This systematic review aimed to examine the effectiveness of simulation-based education for the acquisition and maintenance of competence in UGRA. ⋯ Ultrasound-guided regional anesthesia knowledge and skills significantly improved with simulation training. The acquired UGRA skills may be transferred to the clinical setting; however, further studies are required to confirm these changes translate to improved patient outcomes.

Case ReportsPectoral Fascial (PECS) I and II Blocks as Rescue Analgesia in a Patient Undergoing Minimally Invasive Cardiac Surgery.
Patients undergoing minimally invasive cardiac surgery have the potential for significant pain from the thoracotomy site. We report the successful use of pectoral nerve block types I and II (Pecs I and II) as rescue analgesia in a patient undergoing minimally invasive mitral valve repair. ⋯ Pectoral nerve blocks have been described in the setting of breast surgery to provide chest wall analgesia. We report the first successful use of Pecs blocks to provide effective chest wall analgesia for a patient undergoing minimally invasive cardiac surgery with thoracotomy. We believe that these blocks may provide an important nonopioid option for the management of pain during recovery from minimally invasive cardiac surgery.

Dose-Response Curves for Intrathecal Bupivacaine, Levobupivacaine, and Ropivacaine Given for Labor Analgesia in Nulliparous Women.
Bupivacaine, levobupivacaine, and ropivacaine are often given intrathecally for labor analgesia, but limited data are available for their dose-response properties in this context. The objective of this study was to describe the dose-response curves of these local anesthetics when given intrathecally for labor analgesia, to determine values for D50 (dose producing a 50% response) and to compare the calculated values of D50 for levobupivacaine and ropivacaine with those for bupivacaine. ⋯ Chinese Clinical Trial Registry (identifier: ChiCTR-TRC-09000773) and Centre of Clinical Trials Clinical Registry of the Chinese University of Hong Kong (identifier: CUHK_CCT00245).

Risk Vessels of Retropharyngeal Hematoma During Stellate Ganglion Block.
Bleeding into the retropharyngeal space is a potential complication in stellate ganglion block (SGB). Retropharyngeal hematoma formation is considered to be due to damage of small arteries in the region, although only scanty details of the region are available. The aim of this study was to map the risk blood vessels in the retropharyngeal space to avoid accidental damage during SGB. ⋯ Three-dimensional computed tomography identified the ITA in the medial portion of the ventral surface of the transverse process of the sixth cervical vertebra. The risk vessels of retropharyngeal hematoma during SGB could include the ITA.
