Case Reports
Ultrasound-guided suprascapular nerve block: a correlation with fluoroscopic and cadaveric findings.
Previous work on the ultrasound-guided injection technique and the sonoanatomy of the suprascapular region relevant to the suprascapular nerve (SSN) block suggested that the ultrasound scan showed the presence of the suprascapular notch and transverse ligament. The intended target of the ultrasound-guided injection was the notch. The objective of this case report and the subsequent cadaver dissection findings is to reassess the interpretation of the ultrasound images when locating structures for SSN block. ⋯ Our fluoroscopic and cadaver dissection findings both suggest that the ultrasound image of the SSN block shown by the well-described technique is actually targeting the nerve on the floor of the suprascapular spine between the suprascapular and spinoglenoid notches rather than the suprascapular notch itself. The structure previously identified as the transverse ligament is actually the fascia layer of the supraspinatus muscle.

Randomized Controlled Trial Comparative Study
Ketamine, but not priming, improves intubating conditions during a propofol-rocuronium induction.
Both ketamine and priming may shorten the onset time of rocuronium. This study investigates the effects of ketamine and priming as components of a propofol induction on intubating conditions and onset of neuromuscular block. ⋯ A low-dose ketamine used with a propofol-rocuronium induction improved intubating conditions and shortened onset time. Priming did not influence intubating conditions or onset time.

The objective of this survey was to explore Canadian anesthesiology residents' educational experience with high-fidelity simulation and to improve understanding of the factors perceived to have either a positive or a negative effect on residents' learning. ⋯ Anesthesiology residents indicate that simulation-based education is an anxiety provoking experience, but value its role in promoting safe practice and enhancing one's ability to deal with emergency situations. Suggestions to improve simulation training include increasing residents' access, adopting a more student-centred approach to learning, and creating a safer learning environment.
