What this Trial Is About

Aneurysmal subarachnoid hemorrhage (aSAH) is a dreadful acute neurological condition with overwhelmingly high rate of associated morbidities and mortality. Despite leaping advancement in neurosurgical techniques and imaging modalities, there is no substantiative improvement in overall prognosis for aSAH. Cerebral vasospasm remains the predominant cause of associated morbidities. Human albumin has been used in different neurological conditions including head trauma, intracerebral hemorrhages, and ischemic strokes with favorable outcome. However, its beneficial use in aSAH has not been sufficiently explored until recently a published systematic review by our team. In view of scarcity of published data and lack of robust evidence, our group has designed for the first ever RCT to compare the use human albumin-enhanced fluid management versus standard fluid therapy with crystalloids in patients with aSAH. This single center open label, prospective, parallel group randomized control trial will be conducted at Hamad General Hospital, Doha-Qatar from August 2024 to July 2027. A sample size of 84 (42 in each arm) has been calculated to detect as sufficient to detect a clinically significant difference in modified Rankin Scale good score between two groups (human-albumin induced volume expansion therapy versus crystalloid only) for fluid management in aneurysmal subarachnoid hemorrhages patients. Primary outcome will be based on dichotomized modified Rankin scale \[(Good grades (0-2) and poor grades (3-6)\], while secondary outcome will include symptomatic vasospasm, transcranial doppler velocities, and Pulse Index Contour Cardiac Output (PiCCO) parameters. The trial aims to provide firsthand evidence on the beneficial use of human albumin to achieve optimal fluid management regime to explore its potential role to improve clinical outcome in patients with aSAH.
