ReviewConscious sedation during ophthalmic surgery under local anesthesia.
Sedation during ophthalmic local anesthesia helps to ensure comfort and cooperation during eye surgery. Sedation requirements of ophthalmic patients have changed with the popularization of newer surgical and anesthetic techniques. Many sedative agents are available to anesthesiologists including benzodiazepines, intravenous anesthetic induction agents, narcotic analgesics and a-adrenoreceptor agonists. ⋯ Moreover, the clinical practice of sedation during ophthalmic surgery under local anesthesia is varied and not without risk of complications and adverse events. Hence, balanced sedative techniques should only be used after careful consideration of patient profile, the type of eye surgery, and patient and surgeon preferences. Good knowledge of the pharmacology of sedative agents is fundamental to their useful clinical application.

Pediatric regional anesthesia (PRA) is widely practiced today; reassuring data from international literature show its safety and efficacy. However, for many years, PRA was considered an extravagant and ineffective technique by many detractors.

ReviewManagement to optimize organ procurement in brain dead donors.
The demand for donor organs continues to exceed the number of organs available for transplantation. Many reasons may account for this discrepancy, such as the lack of consent, the absence of an experienced coordinator team able to solve logistical problems, the use of strict donor criteria, and suboptimal, unstandardized critical care management of potential organ donors. This has resulted in efforts to improve the medical care delivered to potential organ donors, so as to reduce organ shortages, improve organ procurement, and promote graft survival. ⋯ Strategies for the management of organ donors exist and consist of the normalization of donor physiology. Management has been complicated by the recent use of ''marginal'' donors and donors of advanced age or with ''extended'' criteria. Current guidelines suggest that the priority of critical care management for potential organ donors should be shifted from a ''cerebral protective'' strategy to a multimodal strategy aimed to preserve peripheral organ function.

Innovation over the past 25 years in the field of the airway management has led to the proliferation of new and improved techniques and devices. It is important to emphasize that the definition of a failed airway must include the inability to maintain acceptable oxygenation and not only the evidence of unsuccessful laryngoscopy and impossible intubation. We must ask ourselves: is it always necessary to intubate? Is it necessary in all patients? Our answer is absolutely ''no." Patients' oxygenation is the absolute priority, where the choice of whether or not to intubate represents only a technical problem. ⋯ Furthermore, the applicability of associated techniques could represent an efficacious strategy to overcome the limitations of the single device by strengthening their capabilities and chances of successful airway management. To date there is no technique found to be effective in every case or that can solve all airway problems. It is not the latest device or the latest technique that can solve an airway management problem, but the operator's experience and skill with the device and technique that he knows best and uses daily.
