Blunt cerebrovascular injury (BCVI) is a non-penetrating injury to the carotid and/or vertebral artery that may cause stroke in trauma patients. Historically BCVI has been considered rare but more recent publications indicate an overall incidence of 1–2% in the in-hospital trauma population and as high as 9% in patients with severe head injury. The indications for screening, treatment and follow-up of these patients have been controversial for years with few clear recommendations. In an attempt to provide a clinically oriented guideline for the handling of BCVI patients a working committee was created. The current guideline is the end result of this committees work. It is based on a systematic literature search and critical review of all available publications in addition to a standardized consensus process. We recommend using the expanded Denver screening criteria and CT angiography (CTA) for the detection of BCVI. Early antithrombotic treatment should be commenced as soon as considered safe and continued for at least 3 months. A CTA at 7 days to confirm or discard the diagnosis as well as a final imaging control at 3 months should be performed.Electronic supplementary materialThe online version of this article (10.1186/s13049-018-0559-1) contains supplementary material, which is available to authorized users.
ObjectThe aim of the study was to evaluate the early changes in pituitary hormone levels after severe traumatic brain injury (sTBI) and compare hormone levels to basic neuro-intensive care data, a systematic scoring of the CT-findings and to evaluate whether hormone changes are related to outcome.MethodsProspective study, including consecutive patients, 15–70 years, with sTBI, Glasgow Coma Scale (GCS) score ≤ 8, initial cerebral perfusion pressure > 10 mm Hg, and arrival to our level one trauma university hospital within 24 hours after head trauma (n = 48). Serum samples were collected in the morning (08–10 am) day 1 and day 4 after sTBI for analysis of cortisol, growth hormone (GH), prolactin, insulin-like growth factor 1 (IGF-1), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), follicular stimulating hormone (FSH), luteinizing hormone (LH), testosterone and sex hormone-binding globulin (SHBG) (men). Serum for cortisol and GH was also obtained in the evening (17–19 pm) at day 1 and day 4. The first CT of the brain was classified according to Marshall. Independent staff evaluated outcome at 3 months using GOS-E.ResultsProfound changes were found for most pituitary-dependent hormones in the acute phase after sTBI, i.e. low levels of thyroid hormones, strong suppression of the pituitary-gonadal axis and increased levels of prolactin. The main findings of this study were: 1) A large proportion (54% day 1 and 70% day 4) of the patients showed morning s-cortisol levels below the proposed cut-off levels for critical illness related corticosteroid insufficiency (CIRCI), i.e. <276 nmol/L (=10 ug/dL), 2) Low s-cortisol was not associated with higher mortality or worse outcome at 3 months, 3) There was a significant association between early (day 1) and strong suppression of the pituitary-gonadal axis and improved survival and favorable functional outcome 3 months after sTBI, 4) Significantly lower levels of fT3 and TSH at day 4 in patients with a poor outcome at 3 months. 5) A higher Marshall CT score was associated with higher day 1 LH/FSH- and lower day 4 TSH levels 6) In general no significant correlation between GCS, ICP or CPP and hormone levels were detected. Only ICPmax and LH day 1 in men was significantly correlated.ConclusionProfound dynamic changes in hormone levels are found in the acute phase of sTBI. This is consistent with previous findings in different groups of critically ill patients, most of which are likely to be attributed to physiological adaptation to acute illness. Low cortisol levels were a common finding, and not associated with unfavorable outcome. A retained ability to a dynamic hormonal response, i.e. fast and strong suppression of the pituitary-gonadal axis (day 1) and ability to restore activity in the pituitary-thyroid axis (day 4) was associated with less severe injury according to CT-findings and favorable outcome.
Biomarker levels are associated with ICP and CPP and reflect different aspects of brain injury as evaluated by CT-scan. The biomarkers might predict mortality. There are several pitfalls influencing the interpretation of biomarker data in respect to ICP, CPP, CT-findings and clinical outcome.
Our data indicate that there might be a gene-induced susceptibility to severe traumatic brain injury and that patients with the APOE ε4 allele may be more predisposed to brain cellular damage measured as S-100B and NSE. Thus, it seems to be of importance to consider the APOE genotype in interpreting the levels of the biomarkers.
The Scandinavian Neurotrauma Committee (SNC) was initiated by the Scandinavian Neurosurgical Society to improve the care of neurotrauma patients. The SNC has presented evidence-based guidelines for initial management of minimal, mild, and moderate head injuries. Separate guidelines are presented for children and adults. The biomarker S100β is included in the adult guidelines in an attempt to reduce computed tomography (CT) usage and costs. The aim of the guidelines is to guide physicians in the emergency department during initial management of adult and pediatric patients with minimal, mild, and moderate head injuries, specifically to decide which patients are to receive CT scanning, admission, or discharge from the emergency department.
The majority of cSDH patients had reduced postural stability that was partly reversed soon after surgery. It was not correlated to hematoma characteristics, indicating that an increased risk to fall is present regardless of hematoma size and midline shift. This must be accounted for when handling these patients and measures taken to prevent further fall accidents during hospital stays.
Background Previous studies have shown variations in management routines for children with traumatic brain injury (TBI) in Sweden. It is unknown if this management has changed after the publication of the Scandinavian Neurotrauma Committee guidelines in 2016 (SNC16). Also, knowledge of current practice routines may guide development of an efficient implementation strategy for the guidelines. The aim of this study is therefore to describe current management routines in paediatric TBI on a hospital/organizational level in Sweden. Secondary aims are to analyse differences in management over time, to assess the current dissemination status of the SNC16 guideline and to analyse possible variations between hospitals. Methods This is a sequential, cross-sectional, structured survey in five sections, covering initial management routines for paediatric TBI in Sweden. Respondents, with profound knowledge of local management routines and recommendations, were identified for all Swedish hospitals with an emergency department managing children (age 0–17 year) via phone/mail before distribution of the survey. Responses were collected via an on-line survey system during June 2020–March 2021. Data are presented as descriptive statistics and comparisons were made using Fisher exact test, when applicable. Results 71 of the 76 identified hospitals managed patients with TBI of all ages and 66 responded (response rate 93%). 56 of these managed children and were selected for further analysis. 76% (42/55) of hospitals have an established guideline to aid in clinical decision making. Children with TBI are predominately managed by inexperienced doctors (84%; 47/56), primarily from non-paediatric specialities (75%; 42/56). Most hospitals (75%; 42/56) have the possibility to admit and observe children with TBI of varying degrees and almost all centres have complete access to neuroradiology (96%; 54/56). In larger hospitals, it was more common for nurses to discharge patients without doctor assessment when compared to smaller hospitals (6/9 vs. 9/47; p < 0.001). Presence of established guidelines (14/51 vs. 42/55; p < 0.001) and written observation routines (16/51 vs. 29/42; p < 0.001) in hospitals have increased significantly since 2006. Conclusions TBI management routines for children in Sweden still vary, with some differences occurring over time. Use of established guidelines, written observation routines and information for patients/guardians have all improved. These results form a baseline for current management and may also aid in guideline implementation.
