Depth of Anesthesia Monitoring: A Survey of Attitudes and Usage Patterns Among Australian Anesthesiologists.
Utility of depth of anesthesia (DoA) monitors is contentious as evidence appears ambiguous regarding their clinical effectiveness and exact role. We conducted a survey of Australian anesthesiologists to determine their attitudes toward, and how and why they use, DoA monitors. ⋯ The relatively frequent use of DoA monitoring contrasts with patterns in the UK, suggesting greater acceptance by Australian anesthesiologists. "Awareness prevention" rather than "recovery enhancement" appears to be the primary driver in DoA monitoring use in Australia. Highly variable usage patterns of DoA monitoring in the context of the current body of evidence suggest the need for greater education on the appropriate use of these monitors.

The Effect of NR2B Subunit Palmitoylation at the Spinal Level After Chronic Dorsal Root Ganglia Compression in Rats.
The NR2B subunit (N-methyl-D-aspartate receptor 2B subunit) regulates the source of pain, and it participates in the formation of central sensitization. Palmitoylation was shown to be involved in the regulation of N-methyl-D-aspartate receptor internalization. In the present study, we investigated the effects of NR2B subunit palmitoylation in a chronic dorsal root ganglia compression (CCD) rat model. ⋯ These data suggest that upregulated NR2B palmitoylation in CCD-induced neuropathic pain and intrathecal injection of 2-BP could reduce pain behaviors and NR2B phosphorylation. Our findings indicate that spinal NR2B palmitoylation is an important component of CCD-induced neuropathic pain, and it might be a potential target for chronic pain therapy.
