![]() Head trauma ICP measurements intracranial pressure monitoring. ![]() Conclusions: Whilst pupillometry may not be a reliable surrogate marker for ICP, NPi may still prove to be a useful tool in a multimodal prognostic assessment of the patient with acute brain injury. The objective of this study was to analyze and validate the outcome of DC in patients with sTBI with BFDP. The strength of this trend appears to diminish post-decompressive surgery. For patients with severe traumatic brain injury (sTBI) with bilateral fixed dilated pupils (BFDP), the value of aggressively decompressive craniectomy (DC) treatment is still controversial. severe traumatic brain injury and bilateral nonreactive dilated pupils. The results show that there is a weak but statistically insignificant relationship between NPi and ICP, where reduced pupil reactivity may indicate a raised ICP. Large decompressive craniotomy in the treatment of acute subdural hematoma. There was a weak relationship between ICP events and a preceding NPi event. Main Outcomes and Results: On average, individuals experienced a few significant events. Significant events were identified for analysis based on the significant aberration of ICP or NPi. Methods and Procedures: We obtained hourly pupillometry readings, alongside ICP values, from 40 patients with TBI requiring invasive ICP monitoring. This condition is known as anisocoria and is present in 15 to 17 of the popula-tion without any known clinical significance.6 Pupil size should be assessed both before and after the pupil responds to direct light. Research Design: Prospective observational. Investigations on decompressive craniectomy after failure of conservative management are scarce, but this surgical treatment should be considered and performed expeditiously, as it lowers the. Although both pupils should be equal in size, a 1-mm discrepancy is consid-ered a normal deviation. ![]() We sought to evaluate this relationship more closely. An impaired response on NPi has been tentatively correlated with ICP, through analysis of mean/peak NPi and ICP readings. Optical pupillometry is a non-invasive, objective monitoring method, measuring parameters of pupillary response and displaying a scalar value - a neurological pupil index (NPi). Primary Objective: Treatment paradigms for traumatic brain injury (TBI) rely on invasive monitoring of intracranial pressure (ICP) for planning intervention.
