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.

Impact of Video Technology for Improving Success of Medial Canthus Episcleral Anesthesia in Ophthalmology.
Efficient learning of regional anesthesia in ophthalmology remains challenging because trainees are afforded limited opportunity to practice ocular anesthesia. The aim of this prospective, randomized, blinded study was to determine whether teaching with video improves regional anesthesia skills of residents in ophthalmology. ⋯ Video-assisted teaching significantly improves performance of medial canthus episcleral anesthesia performed by novice trainees.
