(D) Radiological events over all the ICU stay (Absolute numbers). Transcranial Doppler sonography (TCD) of the vessels of the anterior circulation was performed daily. The .gov means its official. Donate. However, both intravenous and oral administration of nimodipine are common practice and, in addition to intra-arterial rescue therapy, have a relevant role in everyday clinical practice (31). Despite the relatively small sample size, demographics correspond well with other SAH cohorts and epidemiological data. Basic clinical characteristics of our study population including clinical parameters and SAH-relevant events on intensive care unit (ICU) at admission and during hospitalization as well as medical history were collected. Nimodipine is in a class of medications called calcium channel blockers. An analysis of the last day of i.v. Definition of delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage as an outcome event in clinical trials and observational studies: proposal of a multidisciplinary research group. Values for A. cerebri anterior (upper) and A. cerebri media (lower) are depicted separately. Our objective was to compare the effectiveness of intravenous and enteral nimodipine in preventing poor outcome from delayed cerebral ischemia in patients with subarachnoid hemorrhage. doi: 10.1177/1060028018778751, 27. The critical care management of poor-grade subarachnoid haemorrhage, Management of delayed cerebral ischemia after subarachnoid hemorrhage. (B) All TCD values independent of their circulation are depicted. (30). Stroke. This study has a number of limitations, particularly its retrospective, single-center design. Czorlich P, Sauvigny T, Ricklefs F, Abboud T, Nierhaus A, Vettorazzi E, et al. The whiskers represent the 1.5 inter quantile range (IQR). Values for A. cerebri anterior (upper) and A. cerebri media (lower) are depicted separately. Data transformation, calculation and visualization was done in R (version 3.6.3 main packages: dplyr, tidyverse, stringr, ggplot2, ggpubr). Delayed cerebral ischaemia after subarachnoid haemorrhage: looking beyond vasospasm. Switching was neither associated with clinically relevant increases in TCD velocities nor other relevant adverse events. Allen GS, Ahn HS, Preziosi TJ, Battye R, Boone SC, Chou SN, et al. Initial pupil status is a strong predictor for in-hospital mortality after aneurysmal subarachnoid hemorrhage. Patient cohorts were further divided and defined according to these findings: Patients who had an uncomplicated course (UC) represented the major group with 57 patients. Error bars represent the standard deviation. Consult your doctor or pharmacist for details. Statistical analysis was performed with unpaired t-test compared to the last day of i.v. Statistical analysis was performed with paired t-test. Statistical analysis was performed with paired t-test. Make your tax-deductible gift and be a part of the cutting-edge research and care that's changing medicine. This study has a number of limitations, particularly its retrospective, single-center design. If significant differences were to be found, this could be a basis for further investigations, since randomized data are not available at present. To examine correlations between the parameters we calculated the linear regression coefficient. Mean flow velocities were recorded. We have therefore investigated the safety and clinical effects of switching from i.v. There are considerations as to whether oral administration in analgosedated patients could result in lower bioavailability compared to i.v. sharing sensitive information, make sure youre on a federal NS conceived the study question and analyzed and interpreted the data. Data collection included demographic information, aneurysm location, information on antiplatelet aggregation medication, pre-existing conditions and distinct clinical evaluation scores (Glasgow Coma Scale, Hunt & Hess grading system, WFNS grading system, Fisher score). spasmolysis with nimodipine was applicated via a microcatheter as rescue-therapy. doi: 10.1007/s12028-017-0428-1, 32. Even though we explicitly looked into groups with complications and compared them with uncomplicated courses, we found no differences. World Neurosurg. (C) Mean TCD values are shown over the first 20 days of ICU stay for A. cerebri anterior (upper) and A. cerebri media (lower). ns, not significant. The whiskers represent the 1.5 inter quantile range (IQR). TCD values on the last 2 days of Nimodipine iv. The level of statistical significance was set at p < 0.05. With respect to the ACA, mean values of 62.24 cm/s (UC) and 67.50 cm/s (CVS+CI) were recorded. The drug doses were extracted from the intensive care unit's electronic documentation system (Integrated Care Manager, Drger Medical Deutschland GmbH, Lbeck, Germany). All TCD values are depicted and correlated to the Nimodipine iv., oral and Norepinephrine cumulative dosage over 24 h. Linear regression line with the according standard error are depicted for the defined groups. (2012) 78:1019. Sandow et al. Error bars represent the standard deviation. nimodipine (Nimotop S, Bayer Vital, Leverkusen, Germany) therapy with a continuous infusion rate of 2 mg/h, it was continued depending on the level of analgosedation or already evident vasospasms or perfusion deficits. Objective: Several guidelines recommend oral administration of nimodipine as vasospasm prophylaxis after aneurysmal subarachnoid hemorrhage (SAH). 122 b 22083 Hamburg. Mean flow velocities of the MCA 24 h before switching to oral administration were 83.82 cm/s (MCA) and 64.83 cm/s (ACA). and the first 2 days of oral administration only were depicted, together with overlapping dosages. Nimodipine is isopropyl 2-methoxyethyl 1,4-dihydro-2,6-dimethyl-4- ( m -nitrophenyl)-3,5-pyridinedicarboxylate. Values for A. cerebri anterior (left) and A. cerebri media (right) are depicted separately. (2012) 2012:16. Guidelines recommend that all patients receive a fixed dose of oral nimodipine for 21 days. (Figures 3A,B). In the context of this clinically relevant topic, we were able to show that almost no significant change in flow velocities or incidence of negative clinical events occurred after the switch. All patients were treated according to common guidelines and as previously described (22). Albanna W, Weiss M, Conzen C, Clusmann H, Schneider T, Reinsch M, et al. Only patients admitted with aneurysmal SAH between January 2014 and April 2018 and initial i.v. Diringer MN, Zazulia AR. Statistical analysis of the data was performed by a univariate analysis using chi-squared tests, independent-samples Kruskal-Wallis tests or ANOVA tests depending on the scale of the measurements and equality of variances.

The discussed lower oral bioavailability of nimodipine, especially in analgosedated patients, as well as the frequent blood pressure-related interruption of oral administration make i.v. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Based on the strong study evidence and current guideline recommendations, nimodipine should be given p.o. (C) Absolute amount of the radiological events are show according to the administered drug. Statistical analysis was performed with unpaired t-test compared to the last day of i.v. Correlation of Transcranial Doppler Sonography to oral and i.v. In patients unable to swallow but expected enteral absorption, tablets were crushed and washed down a nasogastric tube with normal saline (23, 29). nimodipine therapy, which was subsequently switched to oral administration, were included in this retrospective study. ChildrenUse and dose must be determined by your doctor. (1990) 21:IV-859. per day administration was defined as oral. CVS occurred in 30 cases (22.6%), 19 patients (14.3%) suffered from cerebral infarction without CVS (CI), and CVS+CI occurred in 27 cases (20.3%), Table 1. After the switch, 8 events occurred in the same group, of which 3 were intraarterial spasmolyses with locally administered nimodipine. Physician reviewed nimodipine patient information - includes nimodipine description, dosage and directions. administration of the drug a valid and common alternative (2325). Dots show each value and grey lines connect individual patients' measurements. To examine correlations between the parameters we calculated the linear regression coefficient. Nimodipine has been shown to improve outcomes following aneurysmal subarachnoid hemorrhage. Norepinephrine dose around nimodipine switch [mg/day]. To visualize parameters from the digital patient record, the time since ICU admission was analyzed by day and the mean (point) and standard error of the mean (error bars) were calculated. A treatment of SAH patients with nimodipine was shown in several studies to be effective in reducing incidence of poor outcome and severe neurological deficits after aneurysmal SAH but showed no influence on the occurrence of CVS or DCI (1518). (B) All TCD values independent of their circulation are depicted. after aneurysmal SAH, which was subsequently switched to oral administration after a mean of 11.7 5.78 days. Label oral syringes "Not for IV Use" and dispense in amber oral syringes in labeled, light-protected bags. Vergouwen MDI, Ilodigwe D, MacDonald RL. There were no significant increases in mean flow velocities on TCD after the switch from i.v. TCD values on the last 2 days of Nimodipine iv. (2017) 102:45965. This side effect of nimodipine counteracts the desired induced hypertension, forcing an intermittent interruption, lowering dose of application or concomitant intravenous administration of norepinephrine is often necessary. administration. Medication was extracted as flowrate of a continuous application (nimodipine and norepinephrine) or as time of administration (nimodipine oral). In case of TCD suspicion of vasospasm we perform according to our local treatment protocol a computer tomography (CT) -scan, including computed tomography angiography (CTA) and CT-perfusion imaging (CTP).

Vergouwen MDI, Vermeulen M, van Gijn J, Rinkel GJE, Wijdicks EF, Muizelaar JP, et al. Of these, 18 were intraarterial spasmolyses with locally administered nimodipine. In none of the groups with complications (CVS, CI and CVS+CI) was there a significant increase in flow velocities during the switch or on the days after the switch compared to the days before the switch (last day i.v.) spasmolyses were performed within the first 10 days. The need to administer norepinephrine, which often accompanies intravenous administration, initially keeps patients in the ICU. The whiskers represent the 1.5 inter quantile range (IQR). and the first 2 days of oral administration only were depicted, together with overlapping dosages. For final composition of Figures Adobe Illustrator was used (Adobe Inc., San Jos, USA; Version 24.3). -IV and other parenteral routes should be avoided. Abboud T, Andresen H, Koeppen J, Czorlich P, Duehrsen L, Stenzig J, et al. The clinical relevance of such variability is unknown. Cerebral infarctions were mainly detected in the first 10 days of ICU stay, which is in line with detection of CVS. (B) All TCD values independent of their circulation are depicted. Grouping is done according to radiological findings: Uncomplicated Course (UC), Cerebral Infarction (CI), Cerebral Vasospasms (CVS), and Cerebral Vasospasm and Cerebral Infarctions (CVS + CI). administration was defined only if oral nimodipine was not administered. administration was defined only if oral nimodipine was not administered. In an unpaired analysis, the combination of flow velocities of ACA and MCA showed significantly lower flow velocities among the uncomplicated courses on the first day after the switch (Figure 3B).

Temporal resolution of complications in subgroups in relation to the timing of the switch. doi: 10.3171/2008.7.JNS08178, 33. In case of TCD suspicion of vasospasm we perform according to our local treatment protocol a computer tomography (CT) -scan, including computed tomography angiography (CTA) and CT-perfusion imaging (CTP). Administration of nimodipine is a well-established treatment modality and can happen orally or intravenously (i.v.) (2007) 2007:CD000277. p. 1644. (D) Mean TCD values aligned to the individual switch of the route of administration. An analysis of the last day of i.v. All measurements were performed with the same device (DWL Multi-Dop T Digital, Compumedics Germany GmbH, Singen, Germany) using a 2 MHz frequency ultrasound probe. Nimodipine is a dihydropyridine agent that blocks voltage-gated calcium channels and has a dilatory effect on arterial smooth muscle. In a recent retrospective analysis <50% of all patients on oral nimodipine therapy received the full dose as a consequence of its blood pressure lowering effect, which should be avoided to prevent cerebral infarctions (25). Because there are currently no published head-to-head clinical trials comparing IV vs PO PPIs, we used decision analysis with budget impact . doi: 10.1038/jcbfm.2011.7, 5.
