Background.During hypertensive therapy for post-subarachnoid hemorrhage (SAH) symptomatic vasospasm, norepinephrine is commonly used to reach target blood pressures. Concerns over aggravation of vasospasm with norepinephrine exist.Objective.To describe norepinephrine temporally related deterioration in neurological examination of two post-SAH patients in vasospasm.Methods.We retrospectively reviewed two charts of patients with delayed cerebral ischemia (DCI) post-SAH who deteriorated with norepinephrine infusions.Results.We identified two patients with DCI post-SAH who deteriorated during hypertensive therapy with norepinephrine. The first, a 43-year-old male presented to hospital with DCI, failed MABP directed therapy with rapid deterioration in exam with high dose norepinephrine and MABP of 140–150 mm Hg. His exam improved on continuous milrinone and discontinuation of norepinephrine. The second, a 39-year-old female who developed DCI on postbleed day 8 responded to milrinone therapy upfront. During further deterioration and after angioplasty, norepinephrine was utilized to drive MABP to 130–140 mm Hg. Progressive deterioration in examination occurred after angioplasty as norepinephrine doses escalated. After discontinuation of norepinephrine and continuation of milrinone, function dramatically returned but not to baseline.Conclusions.The potential exists for worsening of DCI post-SAH with hypertensive therapy directed by norepinephrine. A potential role exists for vasodilation and inotropic directed therapy with milrinone in the setting of DCI post-SAH.

OBJECTIVEIn patients with aneurysmal subarachnoid hemorrhage (aSAH), poor outcomes have been shown to be correlated with subsequent cerebral vasospasm (CV) and delayed cerebral ischemia (DCI). The identification of novel biomarkers may aid in the prediction of which patients are vulnerable to developing vasospasm, cerebral ischemia, and neurological deterioration.METHODSIn this prospective clinical study at North Shore University Hospital, patients with aSAH or normal pressure hydrocephalus (NPH) with external ventricular drains were enrolled. The concentration of macrophage migration inhibitory factor (MIF) in CSF was assessed for correlation with CV or DCI, the primary outcome measures.RESULTSTwenty-five patients were enrolled in the aSAH group and 9 were enrolled in the NPH group. There was a significant increase in aggregate CSF MIF concentration in patients with aSAH versus those with NPH (24.4 ± 19.2 vs 2.3 ± 1.1 ng/ml, p < 0.0002). Incidence of the day of peak MIF concentration significantly correlated with the onset of clinical vasospasm (rho = 0.778, p < 0.0010). MIF concentrations were significantly elevated in patients with versus those without evidence of DCI (18.7 ± 4.93 vs 8.86 ± 1.28 ng/ml, respectively, p < 0.0025). There was a significant difference in MIF concentrations between patients with infection versus those without infection (16.43 ± 4.21 vs 8.5 ± 1.22 ng/ml, respectively, p < 0.0119).CONCLUSIONSPreliminary evidence from this study suggests that CSF concentrations of MIF are correlated with CV and DCI. These results, however, could be confounded in the presence of clinical infection. A study with a larger patient sample size is necessary to corroborate these findings.

Introduction: Cerebral vasospasm leading to delayed cerebral ischemia (DCI) is one of the most significant factors impacting functional outcome in patients diagnosed with non-traumatic subarachnoid hemorrhage (SAH). Effective treatment in this setting is lacking. We now report a single center retrospective cohort experience with intrathecal (IT) Nicardipine for this indication. Methods: All patients discharged between 2013-2017 diagnosed with non-traumatic SAH, either aneurysmal or idiopathic, were included in the analysis. Demographics, risk factors, clinical courses, radiological DCI, and functional outcomes were analyzed. Results: 1,085 patients were admitted with aneurysmal (n=796) or idiopathic (n=289) SAH. The mean age was 54.5±14.1 and 67.7% were women. Low grade hemorrhage (WFNS 1) was found in 42.4%, medium (WFNS 2-3) in 26.9%, and high grade (WFNS 4-5) in 30.7%. Cerebral vasospasm was diagnosed in 36.6% of the patients, and 85.4% of those received IT Nicardipine (n=339). Only 8.4% of all patients required angiography to treat vasospasm. TCD data was available for 159 patients who received IT Nicardipine. Treatment reduced mean velocities in all arteries within one day by 15.4% on average (p<0.01). This reduction was sustained for the duration of treatment. Nineteen patients (1.8%) suffered from bacterial ventriculitis, and no statistically significant correlation was noted between IT treatment and infection (OR 1.06 95%CI[0.42-2.7]). The incidence of radiological DCI, identified by blinded assement of imaging, was 9.4% and clinical DCI was 5.7%. In this cohort, 65.5% had a favorable functional outcome (mRS≤2) at 90 days. Conclusions: In a retrospective analysis, off-label IT Nicardipine is a safe and potentially effective treatment for cerebral vasospasm and prevention of the subsequent cerebral ischemia. Being the largest of its kind, this cohort could serve as a baseline for future clinical trial designs assessing IT Nicardipine safety and efficacy in a prospective, controlled fashion.

OBJECTIVE Cerebral vasospasm and delayed cerebral ischemia (DCI) contribute to poor outcome following subarachnoid hemorrhage (SAH). With the paucity of effective treatments, the authors describe their experience with intrathecal (IT) nicardipine for this indication. METHODS Patients admitted to the Emory University Hospital neuroscience ICU between 2012 and 2017 with nontraumatic SAH, either aneurysmal or idiopathic, were included in the analysis. Using a propensity-score model, this patient cohort was compared to patients in the Subarachnoid Hemorrhage International Trialists (SAHIT) repository who did not receive IT nicardipine. The primary outcome was DCI. Secondary outcomes were long-term functional outcome and adverse events. RESULTS The analysis included 1351 patients, 422 of whom were diagnosed with cerebral vasospasm and treated with IT nicardipine. When compared with patients with no vasospasm (n = 859), the treated group was significantly younger (mean age 51.1 ± 12.4 years vs 56.7 ± 14.1 years, p < 0.001), had a higher World Federation of Neurosurgical Societies score and modified Fisher grade, and were more likely to undergo clipping of the ruptured aneurysm as compared to endovascular treatment (30.3% vs 11.3%, p < 0.001). Treatment with IT nicardipine decreased the daily mean transcranial Doppler velocities in 77.3% of the treated patients. When compared to patients not receiving IT nicardipine, treatment was not associated with an increased rate of bacterial ventriculitis (3.1% vs 2.7%, p > 0.1), yet higher rates of ventriculoperitoneal shunting were noted (19.9% vs 8.8%, p < 0.01). In a propensity score comparison to the SAHIT database, the odds ratio (OR) to develop DCI with IT nicardipine treatment was 0.61 (95% confidence interval [CI] 0.44–0.84), and the OR to have a favorable functional outcome (modified Rankin Scale score ≤ 2) was 2.17 (95% CI 1.61–2.91). CONCLUSIONS IT nicardipine was associated with improved outcome and reduced DCI compared with propensity-matched controls. There was an increased need for permanent CSF diversion but no other safety issues. These data should be considered when selecting medications and treatments to study in future randomized controlled clinical trials for SAH.

Norepinephrine Reuptake Inhibitor

Objective: To determine the effect of Selective Serotonin Reuptake Inhibitor (SSRI)/Selective Norepinephrine Reuptake Inhibitor (SNRI) use prior to or during admission for aneurysmal subarachnoid hemorrhage (aSAH) on the risk of symptomatic vasospasm and diffuse cerebral ischemia (DCI). Methods: Review of electronic records at Mayo Clinic, Rochester from Jan. 2001 to Dec. 2013 of consecutive patients with aSAH. The variables collected and analyzed were: age, sex, active smoking, transfusion, modified Fisher score, WFNS grade, and outcome at discharge. Multivariate logistic regression analysis was used to evaluate factors associated with DCI, symptomatic vasospasm, and poor outcome (modified Rankin score 3-6) within 1 year. Results: 583 [females 367 (63%)] patients with a median age of 55 (47-65) years were admitted with aSAH during the study period. WFNS at nadir was IV-V in 243 (41.6%) and modified Fisher score was 3-4 in 438 (75.2%). Eighty one (14.6%) patients were taking SSRI or SNRI prior to admission and these medications were continued in all of them. Symptomatic vasospasm was present in 154 (27.7%), radiological infarction in 172(29.5%), and DCI in 250(42.9%) patients. SSRI/SNRI use was not associated with the occurrence of DCI (p=0.458), symptomatic vasospasm (p=0.097), radiological infarction (p=0.972), or poor functional outcome (p=0.376). Conclusions: The use of SSRI/SNRI prior to admission and/or during hospitalization in patients with aSAH was not associated with symptomatic vasospasm or DCI.
