RESUMO
The Salinity Processes in the Upper-ocean Regional Study (SPURS) aims to understand the patterns and variability of sea surface salinity. In order to capture the wide range of spatial and temporal scales associated with processes controlling salinity in the upper ocean, research vessels delivered autonomous instruments to remote sites, one in the North Atlantic and one in the Eastern Pacific. Instruments sampled for one complete annual cycle at each of these two sites, which are subject to contrasting atmospheric forcing. The SPURS field programs coordinated sampling from many different platforms, using a mix of Lagrangian and Eulerian approaches. This article discusses the motivations, implementation, and first results of the SPURS-1 and SPURS-2 programs.
RESUMO
Pheochromocytomas are rare tumors that produce excessive epinephrine and norepinephrine, leading to multiple manifestations of catecholamine surges. Acute intraoperative hypertension during pheochromocytoma resection requires prompt control to avoid major and potentially lethal cardiac and neurologic complications. This article reports the planned and successful use of clevidipine (Cleviprex) as the "sole agent" for intraoperative blood pressure management in 2 adult patients with a diagnosis of pheochromocytoma undergoing elective open adrenalectomy. Clevidipine effectively and promptly provided predictable blood pressure control in both patients.
