![]() ![]() Despite 74% (20 of 27) of the respondents reporting that TCD results were used to guide aspects of clinical care such as the performance of neuroimaging, titration of drugs to augment cerebral perfusion pressure, and/or the performance of a surgical intervention, only 30% (8/27) reported having a standardized, written protocol for the performance and interpretation of TCD examinations. Most commonly TCD was used in the evaluation and management of patients with intracranial/subarachnoid hemorrhage (SAH) (20 hospitals), arterial ischemic stroke (14 hospitals), and traumatic brain injury (10 hospitals). The use of TCD in critically ill children in the pediatric intensive care unit (PICU) has increasingly being reported.ĩ 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54Ī recent survey of 27 centers that provide pediatric neurocritical care services revealed that 93% use TCD. TCD has had a long-standing role in pediatrics as a tool to identify abnormal CBFVs and then guide therapy to reduce stroke risk in children with sickle cell anemia. Transcranial Doppler ultrasonography (TCD) allows for the noninvasive bedside evaluation and monitoring of cerebral blood flow velocities (CBFVs) in the major cerebral vessels. ![]()
