The role of dexmedetomidine in preventing postoperative delirium (POD) after cardiac surgery remains controversial because of several recent trials with negative results. We aimed to perform an updated meta-analysis of randomized controlled trials (RCTs) to clarify this controversy. ⋯ Dexmedetomidine can reduce the incidence of POD compared to other sedatives and opioids after cardiac surgery in adult patients. The proper population and timing for perioperative use of dexmedetomidine after cardiac surgery remain to be further investigated.

Anesthetic management of an adult with failing Fontan physiology is complicated given inherent anatomical and physiological alterations. Neurosurgical interventions including thromboembolectomy may be particularly challenging given importance of blood pressure control and cerebral perfusion. ⋯ We describe a 29 year old patient born with double outlet right ventricle (DORV) with mitral valve atresia who after multi-staged surgeries earlier in life, presented with failing Fontan physiology. She was admitted to the hospital almost 29 years after her initial surgeries to undergo workup for a dual heart and liver transplant in the context of a failing Fontan with elevated end diastolic pressures, NYHA III heart failure symptoms, and liver cirrhosis from congestive hepatopathy. During the workup in the context of holding anticoagulation for invasive procedures, she developed a middle cerebral artery (MCA) stroke requiring a thromboembolectomy via left carotid artery approach. DISCUSSION AND CONCLUSIONS: This case posed many challenges to the anesthesiologist including airway control, hemodynamic and cardiopulmonary monitoring, evaluation of perfusion, vascular access, and management of anticoagulation in an adult patient in heart and liver failure with Fontan physiology undergoing thromboembolectomy for MCA embolic stroke.

Observational Study
Preoperative anxiety and its association with patients' desire for support - an observational study in adults.
Preoperative anxiety is prevalent and has harmful effects on postoperative outcomes. However, to date, it is still unclear (i) to what extent patients perceive preoperative anxiety as emotionally distressful, (ii) whether patients would welcome support from anesthesiologists in coping with their anxiety, and (iii) whether anxiety scores are useful for everyday clinical practice to determine patients' need for support. ⋯ All patients undergoing surgery should be screened for preoperative anxiety and the resulting desire for support to be able to determine who would welcome support. Anxiety scoring tools do not seem to be useful to identify these patients. By helping patients experience less preoperative anxiety, anesthesiologists may not only reduce patients' emotional distress but also have a positive impact on postoperative outcome.

Randomized Controlled Trial Comparative Study
A pilot study comparing three bend angles for lighted stylet intubation.
For successful lighted stylet intubation, bending the lighted stylet with an appropriate angle is a prerequisite. The purpose of this study was to compare three different bend angles of 70, 80, and 90 degrees for lighted stylet intubation. ⋯ The bend angle of the lighted stylet affected the time required for tracheal intubation and POST in our study. 80 and 90 degrees as a bend angle seem to be acceptable for clinicians in regard to success rate of lighted stylet intubation. Considering the success rate of lighted stylet intubation and POST, the bend angle of 80 degrees might be better than 70 and 90 degrees.

Multicenter Study Comparative Study
Immediate intravenous epinephrine versus early intravenous epinephrine for in-hospital cardiopulmonary arrest.
Intravenous epinephrine has been a key treatment in cardiopulmonary arrest since the early 1960s. The ideal timing for the first dose of epinephrinee is uncertain. We aimed to investigate the association of immediate epinephrine administration (within 1-min of recognition of cardiac arrest) with return of spontaneous circulation (ROSC) up to 24-h. ⋯ Immediate administration of epinephrine in conjunction with high-quality CPR is associated with higher rates of ROSC.
