Background Aneurysmal subarachnoid hemorrhage (SAH) presents occasionally with cardiac arrest (CA). The impact of pre-hospital and emergency room (ER) treatment on outcome remains unclear. Therefore, we investigated the impact of pre-hospital treatment, focusing on lay cardiopulmonary resuscitation (CPR), and ER handling on the outcome of SAH patients with out-of-hospital CA (OHCA). Methods In this bi-centric retrospective analysis, we reviewed SAH databases for OHCA and CPR from January 2011 to June 2021. Patients were analyzed for general clinical and epidemiological parameters. CPR data were obtained from ambulance reports and information on ER handling from the medical records. Data were correlated with patient survival at hospital discharge as a predefined outcome parameter. Results Of 1,120 patients with SAH, 45 (4.0%) were identified with OHCA and CPR, 38 of whom provided all required information and were included in this study. Time to resuscitation was significantly shorter with lay resuscitation (5.3 ± 5.2 min vs. 0.3 ± 1.2 min, p = 0.003). Nineteen patients were not initially scheduled for cranial computed tomography (CCT), resulting in a significantly longer time interval to first CCT (mean ± SD: 154 ± 217 min vs. 40 ± 23 min; p < 0.001). Overall survival to discharge was 31.6%. Pre-hospital lay CPR was not associated with higher survival ( p = 0.632). However, we observed a shorter time to first CCT in surviving patients ( p = 0.065) Conclusions OHCA in SAH patients is not uncommon. Besides high-quality CPR, time to diagnosis of SAH appears to play an important role. We therefore recommend considering CCT diagnostics as part of the diagnostic algorithm in patients with OHCA.
AbstractIntroduction: Delayed cerebral ischemia (DCI) secondary to aneurysmal subarachnoid hemorrhage (SAH) is a feared complication with frequent negative impact on the neurological outcome. Although early diagnosis and treatment is crucial, identifying patients at increased risk is difficult despite clinical risk stratifies such as the VASOGRADE score. Since a reduction in vessel volumes occurs regularly in this cohort and may indicate evolving DCI, the aim of this study was to investigated the reduction in vessel volume in the early brain injury (EBI) phase as an additional predictive marker for the development of DCI. Methods: A bi-centric retrospective case-control study for the period 01/2018 to 12/2020 was conducted. Inclusion criteria were 1) angiographically confirmed aneurysmatic bleeding source and 2) cranial CT (CCT) scan with CT-angiography on admission (SAH onset) and between EBI (day 1–3). Patient-related, disease-specific and outcome parameters (modified Rankin scale (mRs)) were collected. VASOGRADE score was calculated and the volume of M1 segments of the middle cerebral arteries were measured. Subsequently, the occurrence of DCI was unblinded and the data were statistically analyzed. Results: 80 patients met the inclusion criteria, of those 32 developed a DCI. Vessel volume was reduced in the DCI cohort at SAH onset (0.072 ± 0.027 cm3 vs. 0.108 ± 0.029 cm3, p < 0.001) and during EBI period (0.085 ± 0.028 cm3 vs. 0.121 ± 0.029 cm3, p < 0.001). ROC-analysis unveiled a volume of 0.095 cm3 AUC 0.836; p < 0.001) at SAH onset and 0.105 cm3 (AUC 0.837; p < 0.001) for the EBI period as predictive for the development of DCI. The predictive statistical markers of the volume threshold were superior to those of the VASOGRADE score. Conclusions: Our data indicate that a reduction in vessel volume during the early brain injury (EBI) phase is a predictive marker for delayed cerebral ischemia (DCI). Furthermore, the statistical parameters associated with the volume threshold suggest that it serves as a more accurate predictor of DCI risk compared to the VASOGRADE score.
The measurement of quality indicators supports quality improvement initiatives. The German Interdisciplinary Society of Intensive Care Medicine (DIVI) has published quality indicators for intensive care medicine for the fourth time now. After a scheduled evaluation after three years, changes in several indicators were made. Other indicators were not changed or only minimally. The focus remained strongly on relevant treatment processes like management of analgesia and sedation, mechanical ventilation and weaning, and infections in the ICU. Another focus was communication inside the ICU. The number of 10 indicators remained the same. The development method was more structured and transparency was increased by adding new features like evidence levels or author contribution and potential conflicts of interest. These quality indicators should be used in the peer review in intensive care, a method endorsed by the DIVI. Other forms of measurement and evaluation are also reasonable, for example in quality management. This fourth edition of the quality indicators will be updated in the future to reflect the recently published recommendations on the structure of intensive care units by the DIVI.Die Messung relevanter Qualitätsindikatoren unterstützt Initiativen zur Qualitätsverbesserung. Die Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin (DIVI) hat die intensivmedizinischen Qualitätsindikatoren nun zum vierten Mal publiziert. Sie wurden nach drei Jahren überarbeitet und einige Indikatoren wurden angepasst. Andere Indikatoren erfuhren keine oder nur minimale Änderungen. Der Fokus besteht weiter auf relevanten Behandlungsprozessen wie Management von Analgesie und Sedierung, Beatmung und Weaning sowie Infektionen auf der Intensivstation. Die Gesamtzahl von zehn Indikatoren blieb bestehen. Die Entwicklung der Indikatoren erfolgte in der neuen Version nach einem anderen Prozess. Die Transparenz wurde durch Erwähnung der Einzelbeiträge der Autoren sowie auch potenzieller Interessenkonflikte erhöht. Die Anwendung der Qualitätsindikatoren im Peer-Review-Prozess der DIVI ist weiter wesentlicher Schwerpunkt. Aber auch andere Anwendungen, z.B. im Qualitätsmanagement, sind sinnvoll. Diese vierte Auflage der Qualitätsindikatoren wird noch einmal aktualisiert, um die kürzlich veröffentlichten Empfehlungen der DIVI zur Struktur der Intensivstationen zu berücksichtigen.
The influence of preexisting factors on the clinical course of patients with subarachnoid hemorrhage (SAH), such as patient age, arterial hypertension, and aneurysm characteristics, is still a matter of debate. However, the specific impact of the exact aneurysm location has not received adequate attention. Therefore, the aim of this study was to investigate the influence of aneurysm location as a preexisting factor on the clinical course and mortality.The data of consecutive patients with aneurysmal SAH who were treated from October 2010 to July 2020 were retrospectively analyzed. We distinguished four aneurysm locations: the anterior complex, internal carotid artery (ICA), middle cerebral artery (MCA), and posterior circulation. Logistic regression analysis and receiver operating characteristics were used to investigate the influence of aneurysm location on the occurrence of acute hydrocephalus, Delayed Cerebral Ischemia (DCI), neurological outcome, and in-hospital mortality. Neurological outcome was assessed 3 months after discharge using the Glasgow Outcome Scale.A total of 603 patients were included in this study. Patients with MCA aneurysms were 2.52 times less likely to develop acute hydrocephalus compared to patients with anterior complex aneurysms (p = 0.001). Delayed cerebral ischemia occurred most frequently in patients with an anterior complex aneurysm and least frequently in MCA aneurysms (p = 0.014). In ICA aneurysms, mortality was 2.56-fold higher than in patients with aneurysms of the anterior complex (p = 0.006). An additional ROC analysis showed a good prediction for in-hospital mortality when taking the aneurysm's location into account [AUC.855 (CI.817 -0.893)].The aneurysm's location proved to be a significant predictor of acute hydrocephalus, DCI, and in-hospital mortality, demonstrating the impact of this preexisting biological factor on the course of SAH.
Abstract Background Aneurysmal subarachnoid hemorrhage (SAH) as a serious type of stroke is frequently accompanied by a so-called initial thunderclap headache. However, the occurrence of burdensome long-term headache following SAH has never been studied in detail so far. The aim of this study was to determine the prevalence and characteristics of long-term burdensome headache in good-grade SAH patients as well as its relation to health-related quality of life (HR-QOL). Methods All SAH cases treated between January 2014 and December 2016 with preserved consciousness at hospital discharge were prospectively interviewed regarding burdensome headache in 2018. Study participants were subsequently scrutinized by means of a standardized postal survey comprising validated pain and HR-QOL questionnaires. A retrospective chart review provided data on the initial treatment. Results A total of 93 out of 145 eligible SAH patients participated in the study (62 females). A total of 41% (38/93) of subjects indicated burdensome headache at follow-up (mean 32.6 ± 9.3 months). Comparison between patients with (HA+) and without long-term headache (HA-) revealed significantly younger mean age (47.9 ± 11.8 vs. 55.6 ± 10.3 years; p < .01) as well as more favorable neurological conditions (WFNS I/II: 95% vs. 75%; p = .03) in HA+ cases. The mean average headache of the HA+ group was 3.7 ± 2.3 (10-point numeric rating scale), and the mean maximum headache intensity was 5.7 ± 2.9. Pain and HR-QOL scores demonstrated profound alterations in HA+ compared to HA- patients. Conclusions Our results suggest that a considerable proportion of SAH patients suffers from burdensome headache even years after the hemorrhage. Moreover, long-term headache is associated with reduced HR-QOL in these cases.
