There are 2 types of transcranial Doppler ultrasound. In the non-imaging technique, vessels are identified and interrogated based on sound, waveform, and sample depth, often using a transorbital window. The imaging technique involves the use of color Doppler to visualize the vessels themselves, commonly via a transtemporal window. Non-imaging transcranial doppler has long been used as diagnostic tool to assess for intracranial vasospasm in critically ill adults. Imaging transcranial Doppler is a common tool used in the surveillance of children with sickle cell anemia to evaluate for risk of stroke. This presentation describes the use of the imaging transcranial Doppler technique to monitor the intracranial circulation in critically ill children in neurocritical care setting. Read More

Metronidazole is a commonly used and effective antimicrobial agent for gastrointestinal and genitourinary infections throughout the world. Common side effects of nausea, taste/appetite changes, and headache are well known, however, CNS side effects such as cerebellar dysfunction, dysarthria, and seizures have been reported even at therapeutic levels in rare instances.
