Case ReportsSuccessful emergent reintubation using the Aintree intubation catheter and a laryngeal mask airway.
Tracheal extubation can be potentially catastrophic, especially in patients with difficult airways. This article describes a case where planned extubation in a patient with a large tongue lesion led to complete airway obstruction and subsequent cardiac arrest. Reintubation was facilitated using a laryngeal mask airway and an Aintree intubation catheter.

Coagulopathy in surgical patients is an important factor in triggering major perioperative complications, i.e., intra- or postoperative bleeding and thrombo-embolic events associated with an increased mortality and morbidity. Different methods exist to assess the coagulation status of patients before, during and after surgery. Routine coagulation tests have long been considered to be the clinical standard. ⋯ In contrast, thrombelastography and thrombelastometry, which both measure the visco-elastic properties of whole blood, allow the dynamic assessment of a developing clot, from fibrin formation to clot strengthening and clot lysis. Both techniques are increasingly being used in daily clinical practice in order to detect perioperative coagulopathy and to guide predominantly pro-coagulant therapy in different settings. This article provides an overview of both techniques, thrombelastography (TEG) and thrombelastometry (ROTEM), and their field of perioperative application considering of recently published data.

Transcatheter implantation of an aortic valve: anesthesiological management.
Transcatheter aortic valve implantation (TAVI) is an emergent alternative technique to surgery in high-risk patients with aortic stenosis. Here, we describe the anesthesiological management of patients undergoing TAVI at our institution over an 18-month period. ⋯ TAVI is feasible in high-risk patients who would not be able to undergo surgical valve replacement. Hemodynamic management is the main concern of intraoperative anesthesiological management. General or local anesthesia plus sedation are both valid alternative techniques that can be titrated according to patient characteristics. Close postoperative monitoring in the ICU is required.
