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.

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.

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.
