Neuromonitoring with the microdialysis technique is now being utilized at the bedside. Cerebral metabolism monitoring enables identification of clinical events hours or even days before clinical examination changes, providing clinical staff an opportunity for earlier intervention. Cerebral microdialysis also allows clinicians to evaluate the impact of therapeutics on cerebral metabolism and certain metabolic patterns, which can trigger specific alerts and/or clinical protocols. Cerebral metabolism monitoring through microdialysis can guide clinicians to institute therapeutic measures that prevent the occurrence of secondary injury. This article focuses on the state-of-the-art application of cerebral microdialysis, the rationale for its use, and the nursing implications of this technique.

Neuromonitoring in Intensive Care: Focus on Microdialysis and Its Nursing Implications: Erratum
In the title of Table 1 on page 134, the perfusate flow rate was incorrectly given as 0.3 ml/min when this article was published in the June 2009 issue of Journal of Neuroscience Nursing. The correct perfusate flow rate is 0.3 μl/min.
This erratum appears in the August 2009 issue of Journal of Neuroscience Nursing.
