Mechanical Ventilation, Sedation and Neuromonitoring of Patients with Aneurysmal Subarachnoid Hemorrhage in Germany: Results of a Nationwide Survey

Background: Histamine (H) 2 blockers led to a significant increase of the relative bioavailability of nimodipine and therefore may change tolerability of nimodipine in patients with aneurysmal subarachnoid hemorrhage (SAH). Objective: To determine the effect of H2 blockers on outcome of SAH patients being treated with nimodipine on outcomes. Methods: We analyzed data from Cerner Health Facts® which collected data from participating facilities from January 1st, 2000 to July 1st, 2018. We identified SAH patients who underwent endovascular or surgical treatment for intracranial aneurysm and received nimodipine with or without H2 blockers. Outcome was defined by discharge destination and classified into none to minimal disability, moderate to severe disability, or death. Results: A total of 815 (54.8%) of 1488 SAH patients received H2 blockers in addition to nimodipine. There were no differences in rates of cerebral ischemia (8.8% versus 9.8%) or performance of angioplasty (3.8% versus 3.7%) between patients who did or did not receive H2 blockers. There were no differences in rates of intubation/mechanical ventilation (26.0% versus 29.3%) or intra-procedural cerebral infarction (3.4% versus 2.8%) between the two groups. There was no difference in in hospital mortality rates (10.9% versus 10.2%) or none to minimal disability (41.8% versus 38.2%) between patients who did or did not receive H2 blockers. Conclusions: H2 blockers are frequently used with nimodipine in SAH patients and did not appear to adversely affect rates of death or disability. The finding does not support any clinically significant interaction between H2 blockers and nimodipine in SAH patients.

Abstract Objective Mechanical ventilation (MV) has a complex interplay with the pathophysiology of aneurysmal subarachnoid hemorrhage (aSAH). We aim to provide a review of the physiology of MV in patients with aSAH, give recommendations based on a systematic review of the literature, and highlight areas that still need investigation. Data sources PubMed was queried for publications with the Medical Subject Headings (MeSH) terms “mechanical ventilation” and “aneurysmal subarachnoid hemorrhage” published between January 1, 1990, and March 1, 2020. Bibliographies of returned articles were reviewed for additional publications of interest. Study selection Study inclusion criteria included English language manuscripts with the study population being aSAH patients and the exposure being MV. Eligible studies included randomized controlled trials, observational trials, retrospective trials, case-control studies, case reports, or physiologic studies. Topics and articles excluded included review articles, pediatric populations, non-aneurysmal etiologies of subarachnoid hemorrhage, mycotic and traumatic subarachnoid hemorrhage, and articles regarding tracheostomies. Data extraction Articles were reviewed by one team member, and interpretation was verified by a second team member. Data synthesis Thirty-one articles met the inclusion criteria for this review. Conclusions We make recommendations on oxygenation, hypercapnia, PEEP, APRV, ARDS, and intracranial pressure monitoring.

Neurogenic Stunned Myocardium

Introduction: Neurogenic stunned myocardium is well described after aneurysmal subarachnoid hemorrhage. Stress-induced cardiomyopathy (takotsubo cardiomyopathy) is a form of neurogenic stunned myocardium which is not common after subarachnoid hemorrhage. We describe a case report of stress-induced cardiomyopathy (takotsubo cardiomyopathy) after aneurysmal subarachnoid hemorrhage. Case report: A previously healthy postmenopausal woman suffered aneurysmal subarachnoid hemorrhage with consequent hydrocephalus. After external ventricular drainage, craniotomy and aneurysm of the posterior inferior cerebellar artery clipping, patient developed signs of acute coronary syndrome with heart failure. Transthoracic echocardiogram showed left ventricular apical ballooning and hypercontractile basal segments. On chest radiography bilateral pulmonary infiltrates were seen. Mechanical ventilation and continuous sedation were started. Five days after, patient was weaned from mechanical ventilation and extubated. On control echocardiogram, the signs of apical ballooning syndrome resolved. Conclusions: This case and review of the literature suggest stress-induced cardiomyopathy can mimic acute coronary syndrome after aneurysmal subarachnoid hemorrhage.
