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.

We present 3 cardiothoracic surgery cases during which the Drager Perseus A500 anesthesia machine and the iNOmax Delivery System were used concurrently, resulting in ventilator failures while attempting to separate from cardiopulmonary bypass (CPB). The failure was found to be caused by the iNOmax Delivery System sampling line, where negative pressure on the Perseus A500 breathing circuit precipitated a ventilator failure when the machine was brought out of "standby mode." To our knowledge, there is no discussion of this interaction in the literature, and we find this to be an important issue for patient safety during cardiothoracic surgery.

Surgical resection of arteriovenous malformations (AVMs) is indicated in the presence of life-threatening and severe morbidity, including symptomatic heart failure, ischemic pain, and recurrent bleeding, where other less invasive treatment strategies have been unable to halt the progression of disease. We present the challenges encountered in the perioperative care of a 23-year-old man with high output cardiac failure, gangrenous hand, and severe chronic pain undergoing shoulder disarticulation for a high-flow complex AVM of the upper limb.

We report a case of Xp21 deletion syndrome, a contiguous gene syndrome associating glycerol kinase deficiency, Duchenne muscular dystrophy, and congenital adrenal hypoplasia. This results in a contraindication to the use of all halogenated agents and of propofol. ⋯ We were unfortunately unable to document the metabolic consequences of this glycerol load. We suggest that if propofol is deemed necessary in such cases, it should only be used as a bolus dose of a 2% solution.

When incorporated into the 10-second pulse/rhythm check of the advanced life support (ALS) protocol, focused cardiac ultrasound is a useful adjunct to cardiopulmonary resuscitation. In this case series, we demonstrated the feasibility of echocardiographic assessment using subcostal-only view in ALS (EASy-ALS) performed by anesthesiology residents during the periresuscitative period after structured training. Residents obtained diagnostic quality images in 100% of the self-reported cases, which enabled them to identify cardiac motion and potentially reversible causes of hemodynamic instability. Implementation of EASy-ALS into practice requires system-wide changes in cardiac arrest management for consistency, quality, and further evaluation of patient outcomes.
