RESUMO

Rationale: Older adults (≥65 yr old) account for an increasing proportion of patients with severe traumatic brain injury (TBI), yet clinical trials and outcome studies contain relatively few of these patients.Objectives: To determine functional status 6 months after severe TBI in older adults, changes in this status over 2 years, and outcome covariates.Methods: This was a registry-based cohort study of older adults who were admitted to hospitals in Victoria, Australia, between 2007 and 2016 with severe TBI. Functional status was assessed with Glasgow Outcome Scale Extended (GOSE) 6, 12, and 24 months after injury. Cohort subgroups were defined by admission to an ICU. Features associated with functional outcome were assessed from the ICU subgroup.Measurements and Main Results: The study included 540 older adults who had been hospitalized with severe TBI over the 10-year period; 428 (79%) patients died in hospital, and 456 (84%) died 6 months after injury. There were 277 patients who had not been admitted to an ICU; at 6 months, 268 (97%) had died, 8 (3%) were dependent (GOSE 2-4), and 1 (0.4%) was functionally independent (GOSE 5-8). There were 263 patients who had been admitted to an ICU; at 6 months, 188 (73%) had died, 39 (15%) were dependent, and 32 (12%) were functionally independent. These proportions did not change over longer follow-up. The only clinical features associated with a lower rate of functional independence were Injury Severity Score ≥25 (adjusted odds ratio, 0.24 [95% confidence interval, 0.09-0.67]; P = 0.007) and older age groups (P = 0.017).Conclusions: Severe TBI in older adults is a condition with very high mortality, and few recover to functional independence.

RESUMO

BACKGROUND: Fall with head injury is a pervasive challenge, especially in the aging population. Contributing factors for mortality include the development of cerebral contusions and delayed traumatic intracerebral hematoma. Currently, there is no established specific treatment for these conditions. OBJECT: This study aimed to investigate the impact of independent factors on the mortality rate of traumatic brain injury with contusions or traumatic subarachnoid hemorrhage. METHODS: Data were collected from consecutive patients admitted for cerebral contusions or traumatic subarachnoid hemorrhage at an academic trauma center from 2010 to 2016. The primary outcome was the 30-day mortality rate. Independent factors for analysis included patient factors and treatment modalities. Univariate and multivariate analyses were conducted to identify independent factors related to mortality. Secondary outcomes included thromboembolic complication rates associated with the use of tranexamic acid. RESULTS: In total, 651 consecutive patients were identified. For the patient factors, low Glasgow Coma Scale on admission, history of renal impairment, and use of warfarin were identified as independent factors associated with higher mortality from univariate and multivariate analyses. For the treatment modalities, univariate analysis identified tranexamic acid as an independent factor associated with lower mortality (P = 0.021). Thromboembolic events were comparable in patients with or without tranexamic acid. CONCLUSION: Tranexamic acid was identified by univariate analysis as an independent factor associated with lower mortality in cerebral contusions or traumatic subarachnoid hemorrhage. Further prospective studies are needed to validate this finding.

RESUMO

BACKGROUND: Early enteral nutrition (EN) is associated with shorter hospital stay and lower infection and mortality rates in patients with intracerebral haemorrhage. However, high-energy support always causes clinical complications, such as diarrhoea and aspiration pneumonia, and the true benefit of high-energy support in these patients has not been investigated. The appropriate amount of energy support still needs further investigation. Therefore, we are performing a randomised controlled trial to investigate whether early low-energy EN can decrease mortality and feeding-related complications and improve neurological outcomes as compared with high-energy EN in traumatic intracerebral haemorrhage (TICH) patients. METHODS/ANALYSIS: This is a randomised, single-blind clinical trial performed in one teaching hospital. 220 TICH patients will be randomly allocated to one of two groups in a 1:1 ratio: an intervention group, and a control group. The intervention group will receive early low-energy EN (10 kcal/kg/day) and the control group will receive high-energy EN (25 kcal/kg/day) for 7 days. All these patients will be followed up for 90 days. The primary outcome is all-cause 90-day mortality. Secondary outcomes include the modified Rankin score, Glasgow Outcome Scale (GOS) and the National Institutes of Health Stroke Scale (NIHSS). Outcomes will be assessed at admission, 7, 30 and 90 days after onset of this trial. The safety of EN strategies will be assessed every day during hospitalisation. ETHICS AND DISSEMINATION: The trial will be conducted in accordance with the Declaration of Helsinki and has been approved by the ethics committee of Dongyang People's Hospital. The findings will be published in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: ChiCTR-INR-17011384; Pre-results.

RESUMO

BACKGROUND: The fresh frozen plasma (FFP) transfusion threshold and timing for traumatic brain injury (TBI)-associated coagulopathy are controversial. Thus, a multicenter retrospective study was conducted to determine whether or not FFP transfusion is associated with poor outcomes after severe TBI. METHODS: Data from decompressive craniotomy after blunt force trauma that took place between December 2013 and June 2016 were collected in a multicenter chart. The primary outcomes were mortality and survival, as well as worse outcomes (defined as a Glasgow Outcome Scale [GOS] score ≤3) and better outcomes (GOS score ≥4). Secondary outcomes included 90-day survival rates in all patients with or without FFP transfusion, as well as length of hospital stay in patients with a better prognosis (GOS score ≥4). Univariate analysis, bivariate logistic regression, Spearman rank correlation, and Kaplan-Meier analysis were performed to account for the association between perioperative FFP transfusion and different outcomes. RESULTS: Bivariate logistic analysis showed that mortality and worse outcomes were correlated with FFP transfusion and Glasgow Coma Scale score (P < 0.05). Kaplan-Meier analysis suggested that mortality was statistically higher in the FFP transfusion groups compared with the no FFP transfusion groups, regardless of the severity of TBI (P < 0.05). The overall complications, acute respiratory distress syndrome, and pneumonia rate were significantly higher for patients receiving FFP transfusion (P < 0.05). CONCLUSIONS: Increased perioperative FFP infusion was independently associated with mortality or worse outcomes across a spectrum of surgical risk profiles.

RESUMO

OBJECTIVE: Cerebral vasospasm (CVS) occurs regularly between days 3 and 12 after subarachnoid hemorrhage (SAH). Yet, some patients suffering from SAH have long-lasting cerebral vasospasm (LL-CVS, i.e., longer than 14 days). The outcome of these patients with a very long treatment is unknown. METHODS: Patients with SAH were entered into a prospectively collected database. In unconscious patients, CVS was treated until a reversal of CVS was confirmed by imaging. Outcome was assessed with the modified Rankin Scale (mRS; favorable [mRS 0-2] and unfavorable [mRS 3-6]) 6 months after SAH. Data were compared by matched pair analysis. RESULTS: Of 1126 patients, 106 had LL-CVS (9.4%). The mean of treatment was until day 20 (range, 15-42). Of these patients, more than 30% needed treatment longer than 21 days after SAH; 29% had a small intracerebral hematoma (ICH; <50 mL). Hydrocephalus that required external ventricular drainage was present in 81%. Outcomes were favorable in 60%, and 8% died. In the multivariate logistic regression analysis, risk factors for an unfavorable outcome were elderly patients, poor admission status, and the presence of small ICH. Compared with the matched control group, who had "regular-lasting" CVS, patients with LL-CVS had a significant better outcome (60% vs. 49%) and a significant lower mortality rate (8% vs. 27%). CONCLUSION: Patients with LL-CVS had a significant better outcome than patients with "regular-lasting" CVS. Risk factors for worse outcome of patients with LL-CVS were a worse admission status, elderly age, and the presence of small ICH. We recommend using an objective method to validate the reversal of CVS in unconscious patients.

RESUMO

BACKGROUND: While it is accepted practice to remove extradural (EDH) and subdural haematomas (SDH) following traumatic brain injury, the role of surgery in parenchymal traumatic intracerebral haemorrhage (TICH) is controversial. There is no evidence to support Early Surgery in this condition. OBJECTIVES: There have been a number of trials investigating surgery for spontaneous intracerebral haemorrhage but none for TICH. This study aimed to establish whether or not a policy of Early Surgery for TICH improves outcome compared with a policy of Initial Conservative Treatment. DESIGN: This was an international multicentre pragmatic parallel group trial. Patients were randomised via an independent telephone/web-based randomisation service. SETTING: Neurosurgical units in 59 hospitals in 20 countries registered to take part in the study. PARTICIPANTS: The study planned to recruit 840 adult patients. Patients had to be within 48 hours of head injury with no more than two intracerebral haematomas greater than 10 ml. They did not have a SDH or EDH that required evacuation or any severe comorbidity that would mean they could not achieve a favourable outcome if they made a complete recovery from their head injury. INTERVENTIONS: Patients were randomised to Early Surgery within 12 hours or to Initial Conservative Treatment with delayed evacuation if it became clinically appropriate. MAIN OUTCOME MEASURES: The Extended Glasgow Outcome Scale (GOSE) was measured at 6 months via a postal questionnaire. The primary outcome was the traditional dichotomised split into favourable outcome (good recovery or moderate disability) and unfavourable outcome (severe disability, vegetative, dead). Secondary outcomes included mortality and an ordinal assessment of Glasgow Outcome Scale and Rankin Scale. RESULTS: Patient recruitment began in December 2009 but was halted by the funding body because of low UK recruitment in September 2012. In total, 170 patients were randomised from 31 centres in 13 countries: 83 to Early Surgery and 87 to Initial Conservative Treatment. Six-month outcomes were obtained for 99% of 168 eligible patients (82 Early Surgery and 85 Initial Conservative Treatment patients). Patients in the Early Surgery group were 10.5% more likely to have a favourable outcome (absolute benefit), but this difference did not quite reach statistical significance because of the reduced sample size. Fifty-two (63%) had a favourable outcome with Early Surgery, compared with 45 (53%) with Initial Conservative Treatment [odds ratio 0.65; 95% confidence interval (CI) 0.35 to 1.21; p = 0.17]. Mortality was significantly higher in the Initial Conservative Treatment group (33% vs. 15%; absolute difference 18.3%; 95% CI 5.7% to 30.9%; p = 0.006). The Rankin Scale and GOSE were significantly improved with Early Surgery using a trend analysis (p = 0.047 and p = 0.043 respectively). CONCLUSIONS: This is the first ever trial of surgery for TICH and indicates that Early Surgery may be a valuable tool in the treatment of TICH, especially if the Glasgow Coma Score is between 9 and 12, as was also found in Surgical Trial In spontaneous intraCerebral Haemorrhage (STICH) and Surgical Trial In spontaneous lobar intraCerebral Haemorrhage (STICH II). Further research is clearly warranted. TRIAL REGISTRATION: Current Controlled Trials ISRCTN 19321911. FUNDING: This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 19, No. 70.

RESUMO

High plasma proenkephalin A (PENK-A) levels are associated with poor clinical outcome after ischemic stroke. However, not much is known regarding the change of its level in acute intracerebral hemorrhage. Thus, we sought to determine PENK-A in plasma of patients with acute spontaneous basal ganglia hemorrhage and evaluate its relation with disease severity and in-hospital mortality. One hundred and two patients and 100 healthy controls were recruited. Plasma samples were obtained on admission for patients and at study entry for controls. Its concentration was measured by chemoluminescence sandwich immunoassay. Plasma PENK-A levels were substantially higher in patients than in healthy controls (235.5±85.4 pmol/L vs. 90.1±31.3 pmol/L; P<0.0001). A forward stepwise logistic regression selected plasma PENK-A as an independent predictor for in-hospital mortality of patients (odds ratio 1.080, 95% confidence interval 1.018-1.147, P<0.001). A multivariate linear regression demonstrated that plasma PENK-A level was positively associated with National Institutes of Health Stroke Scale (NIHSS) score (t=6.189, P<0.001) and hematoma volume (t=5.388, P<0.001). A receiver operating characteristic curve identified a plasma PENK-A level>267.1 pmol/L predicted in-hospital mortality of patients with 80.0% sensitivity and 74.7% specificity (area under curve, 0.836; 95% confidence interval, 0.750-0.902). Its predictive value was similar to NIHSS score's and hematoma volume's (both P>0.05). However, it did not statistically significantly improve the predictive values of NIHSS score and hematoma volume (both P>0.05). Thus, increased plasma PENK-A levels are associated with disease severity and in-hospital mortality after acute intracerebral hemorrhage.

RESUMO

Multiple trauma in children is rare so that even large trauma centers will only treat a small number of cases. Nevertheless, accidents are the most common cause of death in childhood whereby the causes are mostly traffic accidents and falls. Head trauma is the most common form of injury and the degree of severity is mostly decisive for the prognosis. Knowledge on possible causes of injury and injury patterns as well as consideration of anatomical and physiological characteristics are of great importance for treatment. The differences compared to adults are greater the younger the child is. Decompression and stopping bleeding are the main priorities before surgical fracture stabilization. The treatment of a severely injured child should be carried out by an interdisciplinary team in an approved trauma center with expertise in pediatrics. An inadequate primary assessment involves a high risk of early mortality. On the other hand children have a better prognosis than adults with comparable injuries.

RESUMO

OBJECT: The direct thrombin inhibitor dabigatran has recently been approved in the US as an alternative to warfarin. The lack of guidelines, protocols, and an established specific antidote to reverse the anticoagulation effect of dabigatran potentially increases the rates of morbidity and mortality in patients with closed head injury (CHI). Confronted with this new problem, the authors reviewed their initial clinical experience. METHODS: The authors retrospectively reviewed all cases of adult patients (age ≥ 18 years) who sustained CHI secondary to ground-level falls and who presented to the authors' provisional regional Level I trauma center between February 2011 and May 2011. The authors divided these patients into 3 groups based on anticoagulant therapy: dabigatran, warfarin, and no anticoagulants. RESULTS: Between February 2011 and May 2011, CHIs from ground-level falls were sustained by 5 patients while on dabigatran, by 15 patients on warfarin, and by 25 patients who were not on anticoagulants. The treatment of the patients on dabigatran at the authors' institution had great diversity. Repeat CT scans obtained during reversal showed 4 of 5 patients with new or expanded hemorrhages in the dabigatran group, whereas the warfarin group had 3 of 15 (p = 0.03). The overall mortality rate for patients sustaining CHI on dabigatran was 2 (40%) of 5, whereas that of the warfarin group was 0 (0%) of 15 (p = 0.05). CONCLUSIONS: It is critical for physicians involved in the care of patients with CHI on dabigatran to be aware of an elevated mortality rate if no treatment protocol or guideline is in place. The authors will soon implement a reversal management protocol for patients with CHI on dabigatran at their institution in an attempt to improve efficacy and safety in their treatment approach.

RESUMO

This study investigated the frequency of poor outcome at discharge of acute subdural hematoma (SDH) patients with and without microbleeds. We retrospectively examined the records of 37 patients with acute SDH who were surgically treated with hematoma removal and received magnetic resonance (MR) imaging within 2 weeks of head injury onset. MR images were used to determine the presence or absence of microbleeds and contusional hemorrhage (CH). Patient outcome was categorized as good (moderate disability or good recovery) or poor (severely disability, vegetative state, or dead) according to the Glasgow Outcome Scale at discharge. Microbleeds were found in 23 patients (62%) and CH was found in 26 patients (70%). Fifteen patients (41%) had both microbleeds and CH. Poor outcome at discharge was more common in SDH patients with both microbleeds and CH than in SDH patients with neither microbleeds nor CH (14/15, 93% vs. 14/22, 64%; p = 0.04). Poor outcome at discharge was more common in SDH patients under 60 years of age with microbleeds (6/8, 75%) than patients under 60 years of age without microbleeds (0/4, 0%; p = 0.03). The location of the microbleed was not related to the outcome at discharge. These results suggest that the presence of microbleeds and CH on MR images may indicate poor prognosis in patients with acute SDH.

RESUMO

The neuroprotective activity of recombinant human erythropoietin (rhEPO) loaded poly(lactic-co-glycolic) acid (PLGA) nanoparticles has been observed in rats with model intracerebral post-traumatic hematoma (hemorrhagic stroke). It is established that rhEPO-loaded PLGA nanoparticles produce a neuroprotective effect in rats with hemorrhagic stroke, which is manifested by reduced number of lethal outcomes and animals with neurological disorders. Treatment with rhEPO-loaded PLGA prevented amnesia of passive avoidance reflex (PAR), which was produced by the hemorrhagic stroke, and reduced the area of brain damage caused by the intracerebral hematoma. These effects were recorded during one-week observation period. Native rhEPO exhibited a similar, but much less pronounced effect on the major disorders caused by the model hemorrhagic stroke in rats.

RESUMO

It is believed by many neurosurgeons that in addition to age and neurological status, the CT patterns of traumatic intracerebral haemorrhages are related to outcome. The aim of this study was to find out whether this is the case. The study was conducted in a regional level I trauma centre in Hong Kong. We prospectively collected data of patients with traumatic intracerebral haematomas over a 4-year period. Of 464 patients with head injuries, traumatic intracerebral haematoma was significantly associated with inpatient mortality and one year unfavorable outcome after adjustment for age, sex, post-resuscitation GCS, and presence of acute subdural haematoma. One hundred-and-fourteen patients had traumatic intracerebral haematomas and were included for further analysis. The mean age was 49, the male to female ratio was 2 to 1, and the median Glasgow Coma Scale (GCS) score on admission was 12. Logistic regression analysis showed that age and GCS score/GCS motor component score were significant factors for inpatient mortality, one-year mortality and one-year outcome. There was an association between temporal haematomas and inpatient mortality, subdural haematomas and inpatient mortality, and bilateral haematomas and unfavourable one-year outcome. In patients with severe head injury, a traumatic haematoma of more than 50 ml was associated higher inpatient mortality. In addition to age and GCS score, the CT patterns of bilateral haematomas, temporal haematomas and associated subdural haematomas were suggestive of poor outcome or mortality.

RESUMO

Trauma and emergency department clinicians encounter a growing number of patients admitted with traumatic head injury on prehospital antithrombotic therapies. These patients appear to be at increased risk of developing life-threatening intracranial hemorrhage. It is imperative that trauma clinicians understand the mechanism and duration of commonly prescribed outpatient antithrombotics in order to appropriately assess and treat patients who develop intracranial hemorrhage. This review summarizes current literature on the morbidity and mortality associated with premorbid non-steroidal anti-inflammatory drugs, aspirin, clopidogrel, warfarin, and heparinoids in the setting of traumatic head injury, and also examines the current strategies for reversal of these therapies.

RESUMO

BACKGROUND: Predominantly isolated intracerebral hemorrhage (ICH) is a rare complication after traumatic brain injury that tends to occur in patients with coagulation disorders. METHODS: We developed a minimally-invasive free-hand bedside catheter evacuation procedure using 3D-computerized tomography reconstruction imaging. Twelve patients were retrospectively analyzed. RESULTS: Average duration of the procedure was approximately 15 minutes. After catheter placement, urokinase-lysis ensured successful hemorrhage evacuation. Mean Glasgow coma scale at admission was 10 and mean hemorrhage diameter was 6.3 x 3.9 x 4.2 cm, or 55 mL. Mean hemorrhage reduction was 37 mL or 66% in a mean of 4 days. No catheter-related complications were observed. The 30-day and 6-month mortality rates were 16%. Mean extended Glasgow outcome scale at discharge was 4. After a mean of approximately 19 months, nine patients had a favorable, two an unfavorable outcome. One was lost to follow-up. CONCLUSIONS: In comparison with previously published results, free-hand bedside catheter evacuation is a quick and easy-to-apply technique to evacuate predominantly isolated traumatic supratentorial hemorrhage that can be performed in any intensive care unit.

RESUMO

In spite of great success in research severe traumatic brain injury (TBI) remains the most frequent cause for morbidity and mortality in the age < 45 years. The primary lesion emerges at the moment of trauma. Due to several pathophysiological mechanisms secondary lesions occur that enlarge size of contusions significantly. As a consequence of intracranial bleedings and brain edema intracranial pressure (ICP) increases and threaten the patient. Extent of severity (declared in Glasgow Coma Scale Score [GCS]), expansion and type of bleedings (acute and chronic subdural hemorrhage, epidural bleeding, contusion bleedings and intracerebral hemorrhage) determinate operative and conservative therapy as well as intensive care medicine. A specific feature represents frontobasal lesions that, apart of penetrating injuries, are treated interdisciplinary not before ICP is stable, brain edema declining and coagulation sufficient several days after trauma. A persisting rhinoliquorrhoe cause meningitis up to 85 % within 10 years. Patient with GCS < 8 have to be intubated and controlled ventilated. Basic monitoring does not differ from those of other patients treated at the intensive care ward (sufficient breathing [pO (2), pCO (2)], arterial blood pressure, CBC and coagulation parameters, fluid monitoring and nutrition). Additionally, ICP have to be measured and be treated corresponding to the algorithm of ICP treatment. Complementary, oxygen saturation of brain tissue (ptiO (2)), local cerebral blood flow (r-CBF) and cerebral metabolism (micro dialysis) can be measured. Just the combination of the single monitoring parameters gives evidence of the functional condition of the injured brain and relieved planning and performing of the appropriate therapy.

RESUMO

BACKGROUND: Subjects with moderate head injury are a particular challenge for the emergency physician. They represent a heterogeneous population of subjects with large variability in injury severity, clinical course and outcome. We aimed to determine the early predictors of outcome of subjects with moderate head injury admitted to an Emergency Department (ED) of a general hospital linked via telemedicine to the Regional Neurosurgical Centre. PATIENTS AND METHODS: We reviewed, prospectively, 12,675 subjects attending the ED of a General Hospital between 1999 and 2005 for head injury. A total of 309 cases (2.4%) with an admission Glasgow Coma Scale (GCS) 9-13 were identified as having moderate head injury. The main outcome measure was an unfavourable outcome at 6 months after injury. The predictive value of a model based on main entry variables was evaluated by logistic regression analysis. FINDINGS: 64.7% of subjects had a computed tomographic scan that was positive for intracranial injury, 16.5% needed a neurosurgical intervention, 14.6% had an unfavourable outcome at 6 months (death, permanent vegetative state, permanent severe disability). Six variables (basal skull fracture, subarachnoid haemorrhage, coagulopathy, subdural haematoma, modified Marshall category and GCS) predicted an unfavourable outcome at 6 months. This combination of variables predicts the 6-month outcome with high sensitivity (95.6%) and specificity (86.0%). INTERPRETATION: A group of selected variables proves highly accurate in the prediction of unfavourable outcome at 6 months, when applied to subjects admitted to an ED of a General Hospital with moderate head injury.

RESUMO

BACKGROUND: Landmine explosions cause most of the war injuries in the battlefield and pose a substantial public health risk. Although the lower limbs are usually affected, head injuries also occur. The aim of this study is to describe the types of head injuries caused by the explosion of landmines and the management of the victims. PATIENTS AND METHOD: Fifteen patients who sustained a head injury due to a landmine explosion were treated in the Department of Neurosurgery between 2000 and 2006. The average age of the patients was 22.5 (range between 20 and 33). The Glasgow Coma Scale (GCS) score ranged between 3 and 15 and was 8 or less in 4. Shrapnel, stone and earth were the wounding agents. Four patients underwent neurosurgical treatment and 11, apart from simple scalp closure, had conservative treatment. Ten patients had associated lesions in the other parts of the body including thorax, upper and lower limbs, and the abdomen. FINDINGS: Two patients died. At the time of admission, one had a GCS score of 3 and the other a score of 4. Infection was observed among 4 patients and a cerebrospinal fluid (CSF) fistula in 1 patient. CONCLUSION: Landmines occasionally cause head injuries. Surgical intervention is seldom required and survival is likely unless the patient is in deep coma. Multidisciplinary approaches are required in case there are associated lesions in the other parts of the body.

RESUMO

OBJECTIVE: To determine the scale of acute neurosurgery for severe traumatic brain injury (TBI) in childhood, and whether surgical evacuation for haematoma is achieved within four hours of presentation to an emergency department. METHODS: A 12 month audit of emergency access to all specialist neurosurgical and intensive care services in the UK. Severe TBI in a child was defined as that necessitating admission to intensive care. RESULTS: Of 448 children with severe head injuries, 91 (20.3%) underwent emergency neurosurgery, and 37% of these surgical patients had at least one non-reactive and dilated pupil. An acute subdural or epidural haematoma was present in 143/448 (31.9%) children, of whom 66 (46.2%) underwent surgery. Children needing surgical evacuation of haematoma were at a median distance of 29 km (interquartile range (IQR) 11.8-45.7) from their neurosurgical centre. One in four children took longer than one hour to reach hospital after injury. Once in an accident and emergency department, 41% took longer than fours hours to arrive at the regional centre. The median interval between time of accident and arrival at the surgical centre was 4.5 hours (IQR 2.23-7.73), and 79% of inter-hospital transfers were undertaken by the referring hospital rather than the regional centre. In cases where the regional centre undertook the transfer, none were completed within four hours of presentation-the median interval was 6.3 hours (IQR 5.1-8.12). CONCLUSIONS: The system of care for severely head injured children in the UK does not achieve surgical evacuation of a significant haematoma within four hours. The recommendation to use specialist regional paediatric transfer teams delays rather than expedites the emergency service.
