Looks can be deceiving: Investigating change blindness in an online setting.

In the real world, we often fail to notice changes in our environment. In some cases, such as not noticing a car moving into our lane, the results can be catastrophic. This so-called change blindness has been seen experimentally both through failing to notice changes to images on-screen as well as failing to notice a change in other people's identity. However, less is known regarding how change blindness manifests in virtual settings varying in visual clutter or with varying types of interaction with someone prior to the change. Across two studies (n = 134), participants engaged in an online video chat with a confederate, with two levels of visual clutter (none, a lot) and three levels of interaction (none, light conversations about weather/TV, deeper conversations about goals/greatest regrets). We found no modulation of change blindness rates across perceptual clutter. Curiously, we found a large discrepancy in change blindness rates in Experiment 1 (79%; 52/66) versus Experiment 2 (16%; 11/68) that we explored, leading to some evidence that increasing the level of interaction led to greater change blindness rates, but only for pairs who identified as belonging to different ethnicities. Taken together, our work suggests that we may pay attention to people differently in virtual settings compared to in-person, that in-group and out-group biases may have an effect on change blindness rates, and that while clutter does not seem to affect change blindness rates, one's level of interaction just might.

A Perspective on Wellness in Anesthesiology Residency Programs: A Multi-Strategy Approach.

Addressing resident wellness is an important topic given the high risk for burnout and depression in resident physicians compared with the general U.S. population. This article provides an overview of various approaches to help conceptualize and intervene on resident wellness, based on the 9-strategies framework to improve wellness laid out by Shanafelt and colleagues. This article outlines the most relevant literature in each strategy followed by the authors' experience within their anesthesiology residency program.

Methaemoglobinaemia in the perioperative period with regional block.

Methaemoglobin is a form of haemoglobin with oxidised ferric (+3) iron rather than ferrous (+2) iron, which causes a leftward shift in the oxyhaemoglobin dissociation curve and prevents oxygen delivery. Anaesthesiologists need to be familiar with this differential diagnosis for hypoxia given the use of drugs in the perioperative setting known to induce methaemoglobinaemia, including benzocaine and lidocaine, antibiotics such as dapsone and anaesthetic gases, including nitric oxide. This case report details an interesting case of symptomatic methaemoglobinaemia in the perioperative period in the setting of dapsone use and an erector spinae block performed with ropivacaine.

Spontaneous Spread of Limb Complex Regional Pain Syndrome to the Ipsilateral Face With Ultimate Corneal Abrasion: A Case Report.

Complex regional pain syndrome (CRPS) has the potential to spread from the initial site to distant areas of the body. However, there is a paucity of data reporting the patterns and underlying cause of the spread. This case describes spontaneous, ipsilateral spread of CRPS from the right lower extremity to the orbit, leading to corneal abrasion.
