Following SAH, all FFAs are initially elevated. A secondary elevation occurs between 8 and 10 days after SAH. This study provides preliminary evidence of FFA elevation following SAH and of a potential role for FFAs in SAH-induced vasospasm. A prospective study is warranted to determine if CSF concentrations of FFAs are predictive of vasospasm.

Free fatty acids (FFA) in cerebrospinal fluid (CSF) are well-recognized markers of brain damage in animal studies. Information is limited regarding human CSF in both normal and pathological conditions. Samples of CSF from 73 patients, who had undergone lumbar puncture for medically indicated reasons, came from a core laboratory upon completion of ordered tests. Using high performance liquid chromatography, mean FFA concentrations (microg/L +/- SEM) were: arachidonic 26.14 +/- 3.44; docosahexaenoic 60.74 +/- 5.70; linoleic 105.07 +/- 10.98; myristic 160.38 +/- 16.17; oleic 127.91 +/- 10.13; and palmitic 638.34 +/- 37.27. No differences in FFA concentrations were seen with gender, race, age, and/or indication for lumbar puncture. This is the first study to document normal human CSF FFA concentrations in a large series. Further characterization of FFA in pathological conditions may provide markers for evaluating clinical treatments and assisting in prognostication of neurological disease.

This study shows a significant financial benefit for the Henry Ford Health System during the period when a NI was present in the NICU.

In this study, nicardipine infusion was a safe and moderately effective treatment for BP control in patients with SAH. Although SBP during nicardipine infusion was higher than the pre-specified goal in a significant percentage of hourly observations, this may be due to the drug administration protocol and other factors such as analgesia and sedation.

Gun shot wounds to the brain are among the most devastating causes of morbidity and mortality in the civilian population. The majority of the victims will not survive and for a great number of survivors life becomes an uphill battle with permanent deficits and complications. While the fundamental surgical care of these patients is essentially unchanged, our scientific understanding of the pathophysiological changes and the post-injury care of the victims has been evolving. The purpose of this article is to provide an overview of the current clinical and laboratory advances in understanding and treating gun shot injuries to the brain.
