Ultrasound-guided block of the suprascapular nerve - a volunteer study of a new proximal approach.
The standard approach for the suprascapular nerve block is deep in the supraspinous fossa. However, with this approach, the suprascapular nerve is difficult to visualize by ultrasound. The aim of this study was to describe a new method to visualize and selectively block the suprascapular nerve in a more superficial and proximal location. ⋯ We describe a new ultrasound-guided low-volume local anaesthetic technique to selectively block the suprascapular nerve. The potential clinical role of this new approach remains to be determined.

Case ReportsPeri-operative massive pulmonary embolism management: is veno-arterial ECMO a therapeutic option?
Pulmonary embolism remains an important clinical problem with a high mortality rate. The potential for sudden and fatal hemodynamic deterioration highlights the need for a prompt diagnosis and appropriate intervention. The purpose of the present case report is to describe a successful peri-operative veno-arterial extra corporeal membrane oxygenation (VA-ECMO) implantation for assumed massive pulmonary embolism associated with high hemodynamic instability and severe hypoxemia. ⋯ The patient was able to be mobilized 2 days after the surgery and was transferred to a rehabilitation ward on day 15. At that time, her cognitive functions had fully recovered. ECMO can provide lifesaving hemodynamic and respiratory support in patients with massive pulmonary embolism who are too unstable to tolerate other interventions, who have failed other therapies or for whom other therapies are contraindicated.

ReviewIndocyanine green plasma disappearance rate as dynamic liver function test in critically ill patients.
Indocyanine green (ICG) is a water-soluble fluorescent dye that is bound to plasma protein when administered intravenously. Removal of ICG from the blood depends on hepatic blood flow, function of the parenchymal cells and biliary excretion. ICG elimination is described as a useful dynamic liver function test. ⋯ In conclusion, measuring ICG-PDR is a valuable method for dynamic assessment of liver function, and is found to be a valuable prognostic tool in predicting survival for septic patients, patients presenting with acute liver failure and critically ill patients.

Patient fear of anesthesia complications according to surgical type: potential impact on informed consent for anesthesia.
Past research has explored patients' expectations about the informed consent process. However, it is currently unknown if the complexity of the surgical procedure influences the type of anesthesia-related risks that patients wish disclosed. This study explored fears of anesthesia-related complications and whether these changed based on severity of surgery classification. ⋯ Awareness by anesthesia providers of those fears that patients report may allow for a more personalized approach to providing information that may better allay anxiety. Further, these results may better tailor the informed consent process to one that meets particular patient concerns.
