CT perfusion-guided administration of IV milrinone is associated with a reduction in delayed cerebral infarction after subarachnoid hemorrhage

 With all the worries about Hemorrhagic transformation after tPA administration or Delayed cerebral ischemia after hemorrhage your doctor needs solutions, what are they? You better ask your hospital that question now so when you need that you'll know there are protocols to address the problems. At least if you have a competent? hospital. DO YOU HAVE A COMPETENT HOSPITAL OR NOT?

Abstract

Delayed cerebral ischemia (DCI) after aneurysmal subarachnoid haemorrhage (aSAH) is a singular pathological entity necessitating early diagnostic approaches and both prophylactic and curative interventions. This retrospective before-after study investigates the effects of a management strategy integrating perfusion computed tomography (CTP), vigilant clinical monitoring and standardized systemic administration of milrinone on the occurrence of delayed cerebral infarction (DCIn). The period included 277 patients, and the one 453. There was a higher prevalence of Modified Fisher score III/IV and more frequent diagnosis of vasospasm in the period. Conversely, the occurrence of DCIn was reduced with the management strategy (adjusted OR 0.48, 95% CI [0.26; 0.84]). Notably, delayed ischemic neurologic deficits were less prevalent at the time of vasospasm diagnosis (24 vs 11%,), suggesting that CTP facilitated early detection. In patients diagnosed with vasospasm, intravenous milrinone was more frequently administered (80 vs 54%,) and associated with superior hemodynamics. The present study from a large cohort of aSAH patients suggests, for one part, the interest of CTP in early diagnosis of vasospasm and DCI, and for the other the efficacy of CT perfusion-guided systemic administration of milrinone in both preventing and treating DCIn.
