RESUMO
Cerebral vasospasm is determined as a temporary narrowing of cerebral arteries a few days after an aneurysmal subarachnoid hemorrhage. The onset of this vascular event usually evolves with new neurological deficits or progression of ischemic areas. The success of interventions to treat or revert this condition is not satisfying. In addition to cerebral vasospasm, early brain injury plays an important role as a contributor to subarachnoid hemorrhage's mortality. In this sense, stellate ganglion block appears as an alternative to reduce sympathetic system's activation, one of the main pathophysiological mechanisms involved in brain injury. Over the past few years, there is growing evidence that stellate ganglion block can contribute to decline patient morbidity from subarachnoid hemorrhage. Is it time to include this procedure as a standard treatment after aneurysm rupture?
RESUMO
BACKGROUND: Pregnancy can trigger several pathological changes, thus representing a great challenge for gynecology and obstetrics. The objective is to evaluate high- and low-risk pregnant women through Intracranial pressure (ICP) and laboratory parameters. METHODS: Volunteers clinical and laboratory data were collected from medical records and ICP was monitored through noninvasive method. RESULTS: Statistically significant differences were observed between the group of high-risk and low-risk pregnant women for serum levels of alkaline phosphatase (ALP) and US-C-reactive protein (CRP) and a statistically positive association between blood pressure (BP) levels and plasma glucose. About 12.77% of the volunteers presented altered ICP. Higher BP values were encountered with the higher plasma glucose values. All ICP altered volunteers presented altered BP. ALP is among the most effective biochemical markers for assessing the risk of premature birth before 32 weeks of gestation. CONCLUSION: We have observed important changes on BP, serum glucose, US-CRP, and ALP thus indicating higher risk of complications during pregnancy. Even more, some of the volunteers presented altered ICP what could indicate cerebral compliance changes.
