Rapid atrial arrhythmias affect the elderly who undergo cardiac or noncardiac operations annually and have been associated with prolonged hospital stays. This article focuses on new issues leading to the improved understanding of the pathophysiology and mechanisms of postoperative atrial arrhythmias. ⋯ Recent approaches directed at prophylaxis and acute therapy of atrial arrhythmias are discussed as are recommendations to prevent thromboembolic events.

EditorialManagement of the patient with a large anterior mediastinal mass: recurring myths.
This editorial review summarizes the current anesthetic management of patients with anterior mediastinal masses. ⋯ General anesthesia is not safe in patients with severe positional symptoms from an anterior mediastinal mass. With modern imaging techniques, general anesthesia is rarely needed for diagnostic procedures in these patients. Preoperative flow-volume loops are not useful in the management of these patients and the concept of cardiopulmonary bypass on 'standby' is not appropriate during induction of anesthesia.

ReviewWhich muscle relaxants should be used in day surgery and when.
After myorelaxants, myalgia and residual curarization may complicate recovery. Local anaesthesia and minimally invasive airway management make myorelaxants disputable in many outpatient procedures; nevertheless, neuromuscular blockade may be necessary to facilitate intubation or maintain muscle relaxation. Agent selection criteria are discussed. ⋯ Ear-nose-throat, open eye surgery and laparoscopy may demand myoresolution. Regional and minimally invasive anaesthesia are alternative solutions. Central and peripheral nerve blocks are associated with increased induction time, reduced pain scores, and decreased need for analgesics. Central neuraxial block, however, is associated with prolonged outpatient unit stay. Bad intubating conditions may cause pharyngo-laryngeal complications: the decision to avoid myorelaxants for tracheal intubation appears illogical. Incidence of postoperative residual curarization remains very high. Sugammadex offers new perspectives.
