The purpose of this narrative review is to summarize the evidence derived from randomized controlled trials (RCTs) regarding established approaches and techniques for brachial plexus anesthesia. ⋯ Published reports of RCTs provide evidence to formulate limited recommendations regarding optimal approaches and techniques for brachial plexus anesthesia. Further well-designed and meticulously executed RCTs are warranted, particularly in light of new techniques involving ultrasound or combining neurostimulation and echoguidance.

Case Reports
Repetitive generalized seizure-like activity during emergence from sevoflurane anesthesia.
Sevoflurane-induced seizures are most often described during mask induction of anesthesia when high concentrations of the volatile agent are administered concomitant with alveolar hyperventilation. The occurrence of seizure-like activity during emergence from sevoflurane anesthesia has been rarely reported. ⋯ The report emphasizes that sevoflurane is capable of producing excitatory central nervous system (CNS) phenomena in spite of causing primarily CNS depressant effects.

To describe the anesthetic and peripartum management of a parturient with paroxysmal nocturnal hemoglobinuria complicated by severe preeclampsia, review the pathophysiology of this condition, rationale for thromboembolic prophylaxis, and its implications on the choice of labour analgesia and anesthesia. ⋯ Paroxysmal nocturnal hemoglobinuria is associated with an increased risk of venous thromboembolism, and so anticoagulation therapy assumes primary importance. The use of LMWH for prophylaxis in combination with thrombocytopenia may contraindicate neuraxial anesthesia. General anesthesia should be aimed at preventing or exacerbating complement mediated intravascular hemolysis.
