Do initially non-dehydrated patients with acute ischemic stroke need fluid supplement?

Background: We previously found that dehydration is an independent predictor of early deterioration after acute ischemic stroke and rehydration helps to improve outcomes. There is limited evidence of how to treat patients who are initially non-dehydrated. In this study, we tested the hypothesis that rehydration therapy, based on the daily urine specific gravity, will improve the outcome of ischemic stroke patients who are initially non-dehydrated. Methods: We conducted a single-arm prospective study of patients with acute ischemic stroke with historical controls. For the first 5 days of study group, a daily urine specific gravity of > 1.020 g/ml was taken as indication for rehydration and patients were advised to drink water via oral or tubal feeding with a dose of 5 ml/kg body weight right away and after dinner. Control group patients were rehydrated without reference to urine specific gravity. An increase in National Institutes of Health Stroke Scale score of ≥ 4 within three days was defined as having stroke-in-evolution. Scores of ≤ 1 on the modified Rankin scale at 3 months were considered to indicate a favorable outcome. Results: A total of 125 patients were analyzed, 46 in the study group and 79 in the control group. The groups did not significantly differ in the stroke-in-evolution rate (4.3% vs. 8.2%, P = 0.474). The rate of favorable outcome at 3 months was significantly higher in the study group than in the control group (56.5% vs. 27.8%, P = 0.001). Conclusions: Urine specific gravity-based hydration might be a useful method to improve functional outcomes of patients with acute ischemic stroke who were non-dehydrated at admission.

Urine-Specific Gravity-Based Hydration Prevents Stroke in Evolution in Patients with Acute Ischemic Stroke.

BACKGROUND: Early neurological deterioration after ischemic stroke (stroke-in-evolution [SIE]) is associated with poorer outcomes. Previous studies have demonstrated a link between hydration status and the development of SIE. In this study, we tested the hypothesis that rehydration therapy, administered on the basis of urine-specific gravity (USG) findings, might reduce the development of SIE. METHODS: We conducted a single-arm prospective study of patients with acute ischemic stroke with historical controls. For the study group, a USG higher than 1.010 was taken as an indication for rehydration. Control group patients were rehydrated without referring to USG. An increase in National Institutes of Health Stroke Scale (NIHSS) score of 4 or higher within 3 days was defined as having SIE. RESULTS: A total of 445 patients were analyzed, 167 in the study group and 278 in the control group. The proportion of patients who developed SIE was numerically, but not significantly, lower in the study group (5.9%; 10 of 167) compared with the control group (11.5%; 32 of 278). Among patients with a USG higher than 1.010 at admission, the SIE rate was significantly reduced in the study group compared with the control group (6.1% versus 16.0%; P = .021), while the rate of SIE was similar in those with a USG of 1.010 or lower at admission. Multivariate logistic regression analysis confirmed that USG-based hydration was an independent factor associated with reducing SIE. CONCLUSIONS: USG might be a convenient and useful method for guiding fluid therapy in patients with acute ischemic stroke. USG-based hydration reduced the incidence of SIE among patients with a USG higher than 1.010 at admission.

Favorable outcome of blood urea nitrogen/creatinine-based hydration therapy 3 months after acute ischemic stroke.

BACKGROUND: Dehydration is associated with acute ischemic stroke. However, the relationship between hydration therapy given during acute ischemic stroke and clinical outcomes remains unclear. AIMS: We determined whether hydration therapy in patients with a blood urea nitrogen/creatinine (BUN/Cr) ratio of at least 15 improved clinical outcome. METHODS: We conducted a nonblinded, phase II, single-arm, prospective study of patients with acute ischemic stroke and BUN/Cr ratio of at least 15 with historical controls. The hydration group received intravenous bolus (300-500 mL) saline followed by maintenance saline infusion (40-80 mL/h for the first 72 hours), whereas the control group received maintenance saline infusion (40-60 mL/h for the first 24 hours and 0-60 mL/h for 24-72 hours after stroke). The study end point was the percentage of patients with a favorable outcome defined as modified Rankin scale score of 2 or lower at 3 months after stroke. RESULTS: A total of 237 patients were enrolled (hydration, n = 134; control, n = 103). The mean volume of saline infused within the first 72 hours was significantly larger (P < .001), and the rate of favorable outcome at 3 months after stroke was significantly higher (P = .016) in the hydration group than in the controls. Further analysis revealed that the difference was significant in the lacunar stroke subtype (P = .020) but not in the nonlacunar subtype. CONCLUSIONS: Blood urea nitrogen/Cr ratio-based saline hydration therapy in patients with acute ischemic stroke significantly increased the rate of favorable clinical outcome with functional independence at 3 months after stroke.

Red cell distribution width is an independent predictor of mortality in necrotizing fasciitis.

INTRODUCTION: Necrotizing fasciitis (NF) is a rapidly progressing and potentially lethal infectious disease of the soft tissue. An elevated red blood cell distribution width (RDW) is associated with increased risk of death in patients with heart disease and infectious disease. We retrospectively assessed the association of elevated RDW with in-hospital mortality due to NF. METHODS: All patients had diagnoses of NF and were admitted to the emergency department of a single institution in Taiwan over a 4-year period. Demographics, comorbidities, clinical presentations, and laboratory parameters were retrospectively reviewed. Red blood cell distribution width was categorized as elevated (>14.5%) or not elevated. Multivariate regression analysis was used to identify risk factors associated with mortality. RESULTS: A total of 98 patients were enrolled, and the mortality rate was 23%. Univariate analysis indicated that advanced age, initial hypotension, low hemoglobin level, and elevated RDW (69.6% vs 20%, OR = 9.14, P < .001) were significantly associated with mortality. Multivariate analysis indicated that RDW was a significant and independent predictor of mortality in enrolled patients. CONCLUSIONS: Elevated RDW is a significant and independent predictor of in-hospital mortality for patients with NF.

Waist-to-height ratio, waist circumference, and body mass index as indices of cardiometabolic risk among 36,642 Taiwanese adults.

PURPOSE: We aimed to investigate the association of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) with cardiometabolic risk. METHODS: In this cross-sectional study, 21,038 men and 15,604 women who participated in a health check-up were included. RESULTS: In both men and women, the area under the curve (AUC) of WHtR was significantly greater than that of BMI or WC in the prediction of diabetes, hypertension, high total cholesterol, high triglycerides, and low HDL-cholesterol (P < 0.05 for all). The AUC for WHtR in the prediction of metabolic syndrome (MS) was also highest in the women (P < 0.05). After adjustment for potential confounders, the odds ratios and 95% confidence intervals for MS for each standard deviation increase in BMI, WHtR, and WC were 1.47 (1.46-1.49), 1.32 (1.31-1.33), and 1.19 (1.18-1.19), respectively. Finally, patients of either sex with a normal BMI or WC level, but with an elevated WHtR, had higher levels of various cardiometabolic risk factors in comparison with their normal BMI or WC, but low WHtR, counterparts (P < 0.05 for all). CONCLUSION: Among Taiwanese adults, a WHtR greater than 0.5 is a simple, yet effective indicator of centralized obesity and associated cardiometabolic risk, even among individuals deemed 'healthy' according to BMI and WC.

Is direct transport to a trauma centre best for patients with severe traumatic brain injury? A study in south-central Taiwan.

OBJECTIVE: This study attempted to identify any differences between the outcomes of patients with severe traumatic brain injury (TBI) who were directly transported to Chang Gung Memorial Hospital and those who were stabilised initially at other hospitals in south-central Taiwan. METHODS: A retrospective review of the records of 254 patients with isolated severe TBI who visited this hospital's emergency department from July 2003 to June 2008, of whom 167 were referred from other hospitals. Logistic regression was used to assess the effects of transfer and its components on mortality. RESULTS: Transfer from another hospital was not significantly correlated with mortality in this study (OR 0.513, 95% CI 0.240 to 1.097). Moreover, neither intubation (OR 1.356, 95% CI 0.445 to 4.133) nor transfer time over 4 h (OR 0.549, 95% CI 0.119 to 1.744) had a significant effect on mortality. CONCLUSION: No differences in outcome were found between patients with isolated severe TBI who were directly transported and those transferred to this hospital's emergency room.

Differentiating necrotizing soft tissue infections from cellulitis by soft tissue infectious fluid analysis: a pilot study.

BACKGROUND: We conducted this study to evaluate the characteristics of the infectious fluid in soft tissue infection and investigate the utility of the biochemical tests and Gram stain smear of the infectious fluid in distinguishing necrotizing soft tissue infection (NSTI) from cellulitis. METHODS: This retrospective cohort study was conducted in a tertiary care hospital in Taiwan. From April 2019 to October 2020, patients who were clinically suspected of NSTI with infectious fluid accumulation along the deep fascia and received successful ultrasound-guided aspiration were enrolled. Based on the final discharge diagnosis, the patients were divided into NSTI group, which was supported by the surgical pathology report, or cellulitis group. The t test method and Fisher's exact test were used to compare the difference between two groups. The receiver-operator characteristic (ROC) curves and area under the ROC curve (AUC) were used to evaluate the discriminating ability. RESULTS: Total twenty-five patients were enrolled, with 13 patients in NSTI group and 12 patients in cellulitis group. The statistical analysis showed lactate in fluid (AUC = 0.937) and LDH in fluid (AUC = 0.929) had outstanding discrimination. The optimal cut-off value of fluid in lactate was 69.6 mg/dL with corresponding sensitivity of 100% and specificity of 76.9%. The optimal cut-off value of fluid in LDH was 566 U/L with corresponding sensitivity of 83.3% and a specificity of 92.3%. In addition, albumin in fluid (AUC = 0.821), TP in fluid (AUC = 0.878) and pH in fluid (AUC = 0.858) also had excellent diagnostic accuracy for NSTI. The Gram stain smear revealed 50% bacteria present in NSTI group and all the following infectious fluid culture showed bacteria growth. CONCLUSIONS: The analysis of infectious fluid along the deep fascia might provide high diagnostic accuracy to differentiate NSTI from cellulitis.

Serum leptin is associated with cardiometabolic risk and predicts metabolic syndrome in Taiwanese adults.

BACKGROUND: Leptin is associated with cardiovascular disease (CVD); however, few studies have assessed its relationship with metabolic syndrome, especially in an Asian population. Therefore, the aim of the present study was to assess leptin levels and evaluate its association with CVD and metabolic syndrome. METHODS: In 2009, 957 subjects, who underwent a routine physical examination and choose leptin examination, were selected to participate. Participants (269 females and 688 males) were stratified according to leptin level quartiles. Metabolic syndrome was defined by NCEP ATP III using waist circumference cutoffs modified for Asian populations, and CVD risk was determined using the Framingham Heart Study profile. RESULTS: Leptin levels were correlated with CVD risk in men and women. With the exception of fasting plasma glucose, increased leptin levels were observed as factors associated with metabolic syndrome increased in both males and females. After adjusting for age, an association between leptin levels and metabolic syndrome was observed. After adjusting for age alone or with tobacco use, subjects in the highest leptin quartile had a higher risk of having metabolic syndrome than those in the lowest quartile (OR=6.14 and 2.94 for men and women, respectively). After further adjustment for BMI, metabolic syndrome risk remained significantly increased with increasing leptin quartiles in men. Finally, increased leptin levels were a predictor of metabolic syndrome in men and women. CONCLUSIONS: Serum leptin levels are correlated with CVD risk and metabolic syndrome. Analysis of leptin as part of routine physical examinations may prove beneficial for early diagnosis of metabolic syndrome.

The association between anemia and the mortality of severe traumatic brain injury in emergency department.

BACKGROUND: Anemia is a common medical problem for critically ill patients. Blood transfusion to augment oxygen delivery for these patients has been a traditional therapy. However, few studies have identified the impact of anemia on individuals suffering from severe traumatic brain injury (TBI). Hence, this study aims to evaluate the effects of initial anemia on patients with severe TBI admitted to the Emergency Unit. METHODS: We reviewed the medical records of patients with isolated severe TBI admitted to the Emergency Unit of a university hospital from July 2003 to June 2008. Patients were divided into two groups based on their initial anemia data taken while in the Emergency Unit. The anemia datum is defined as hemoglobin (Hb) <10 mg/dL. The t test was used to identify the differences between the two groups, while logistic regression was applied to determine any significant differences found in the statistical analysis. RESULTS: A total of 234 patients were signed up in our study. Based on their initial hemoglobin at emergency department, 23 patients (9.8%) comprised the anemia group, 17 patients (7.3%) comprised the nonanemia group, whereas 112 patients (47.9%) belonging to the nonanemia group were deceased. There is no significant difference between the two groups (p = 0.076; odds ratio, 0.97; confidence interval, 0.78-1.05). CONCLUSION: This study shows that initial anemia is not a mortality risk factor for patients with isolated severe blunt TBI.

The association between skull bone fractures and outcomes in patients with severe traumatic brain injury.

BACKGROUND: In traumatic brain injury (TBI), computed tomography (CT) provides a good assessment of anatomic pathologic findings and the prognostic value of CT characteristics has been well discussed. However, few studies have focused on skull bone fracture and its clinical prognostic importance. Hence, this study aims to evaluate the effects of skull bone fracture on patients with severe TBI admitted to the emergency unit. METHODS: We reviewed the medical records of patients with isolated severe TBI admitted to the emergency unit of a university hospital from July 2003 to June 2008. Patients were divided into two groups based on the presence of skull bone fracture identified by the CT scan while in the emergency unit. Mann-Whitney U test and a Student's t test were used to identify the differences between the two groups, whereas logistic regression was applied to determine any significant differences found in the statistical analysis. RESULTS: A total of 197 patients were signed up in our study. Based on the presence of skull bone fracture on CT scan at emergency department, 92 patients (46.7%) comprised the skull bone fracture group and 59 patients (64.1%) of these died. One hundred five patients (53.3%) comprised the nonskull bone fracture group, of which 33 patients (31.4%) died. There is significant difference between the two groups (p = 0.004). CONCLUSION: This study shows that skull bone fracture is a mortality risk factor for patients with isolated severe blunt TBI.

Corrigendum: The Association Between Emergency Department Revisit and Elderly Patients.

[This corrects the article on p. 20 in vol. 10.].

The Association Between Emergency Department Revisit and Elderly Patients.

BACKGROUND: Emergency department (ED) revisits may be associated with a higher percentage of adverse events and increased costs. Our hospital is a university affiliation hospital accepted regional referral patients, and located in the region in Taiwan with the highest percentage of elderly people. In this study, we attempted to identify whether old age was a risk factor of ED revisit. METHODS: Patients who visited the ED from July 2011 to June 2016 were included. Factors associated with revisit were collected from medical information database. A total of 239,405 patients were included in our study, with 13,272 having ED revisits within 72 hours. Chi square and independent t test were applied for univariable factors, and a logistic regression model was used for multivariable analysis. RESULTS: Old age (age ≥ 65 years) was found to be a risk factor for ED revisit (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.09-1.19). Diagnosis, pulse rate, diastolic blood pressure, fever, pain management, paracentesis, triage level, registration category, male gender, discharge status, and major illness may have some effect on ED revisit. CONCLUSIONS: In our patients, old age is a risk factor for ED revisit; however, only a weak association was found.

Factors associated with outcomes in traumatic cardiac arrest patients without prehospital return of spontaneous circulation.

BACKGROUND: Prognostic factors for the outcomes in traumatic cardiac arrest (TCA) patients transported to hospitals without prehospital return of spontaneous circulation (ROSC) remain uncertain. The aim of this study is to investigate factors associated with outcomes in TCA patients without prehospital ROSC. METHODS: We conducted a retrospective cohort study using a multi-institutional, 5-year database. Only TCA patients without prehospital ROSC were included. The primary outcome was ROSC in the emergency department (ED), and the secondary outcome was 30-day survival. Logistic regression analysis was performed to determine the factors associated with primary and secondary outcomes. RESULTS: Among 463 TCA patients, 73 (16%) had ROSC during ED resuscitation, and among those with sustained ROSC, 10 (14%) survived for at least 30 days. Injury severity score ≧ 16 (OR, 0.06; 95% CI: 0.02-0.20), trauma center admission (OR, 2.69; 95% CI: 1.03-7.03), length of ED resuscitation (OR, 0.98; 95% CI: 0.96-0.99), and total resuscitation length > 20 min (OR, 0.21; 95% CI: 0.08-0.54) were associated with ROSC. CONCLUSIONS: In TCA patients transported to hospitals without prehospital ROSC, resuscitation attempts could be beneficial. We should aim to resuscitate patients as soon as possible with appropriate treatments for trauma patients, early activation of trauma team, and then, as a result, shorter resuscitation time will be achieved.

The Relationship Between Fluid Accumulation in Ultrasonography and the Diagnosis and Prognosis of Patients with Necrotizing Fasciitis.

Necrotizing fasciitis is a severe soft-tissue infection with a high mortality rate. There is little literature on the relationship between the ultrasonographic finding of fluid accumulation along the deep fascia and the diagnosis and prognosis of necrotizing fasciitis. This retrospective study showed that when fluid accumulation was present along the deep fascia, patients with clinically suspected necrotizing fasciitis had a higher probability of having necrotizing fasciitis. The ultrasonographic finding of fluid accumulation with a cutoff point of more than 2 mm of depth had the best accuracy (72.7%) for diagnosing necrotizing fasciitis. In regard to the prognosis of necrotizing fasciitis, when fluid accumulation was present along the deep fascia, patients with necrotizing fasciitis had a longer length of hospital stay and were at risk of amputation or mortality. Ultrasonography is a point-of-care imaging tool that facilitates the diagnosis and prognosis of necrotizing fasciitis.

Massive transfusion in upper gastrointestinal bleeding: a new scoring system.

Background: Massive transfusion in patients with upper gastrointestinal bleeding (UGIB) was not investigated. We developed a new scoring system to predict massive transfusion and to enhance care and early resource mobilization. Methods: Massive transfusion was defined as transfusion with ≥10 units of red blood cells within the first 24 h. Data were extracted from a 10-year, six-hospital database. Logistic regression was applied to derive a risk score for massive transfusion using data from 2006 to 2010, in 24,736 patients (developmental cohort). The score was then validated using data from 2011 to 2015 in 27,449 patients (validation cohort). Area under the receiver operating characteristic (AUROC) curve was performed to assess prediction accuracy. Results: Five characteristics were independently associated (p < .001) with massive transfusion: presence of band-form cells among white blood cells (band form >0), international normalized ratio (INR) >1.5, pulse >100 beats per minute or systolic blood pressure <100 mmHg (shock), haemoglobin <8.0 g/dL and endoscopic therapy. The new scoring system successfully discriminated well between UGIB patients requiring massive transfusion and those who did not in both cohorts (AUROC: 0.831, 95%CI: 0.827-0.836; AUROC: 0.822, 95% CI: 0.817-0.826, respectively). Conclusions: The new scoring system predicts massive transfusion requirement in patients with UGIB well. Key messages Massive transfusion is a life-saving management in massive upper gastrointestinal bleeding. How to identify patients requiring massive transfusion in upper gastrointestinal bleeding is poorly documented. Approximately 3.9% of upper gastrointestinal bleeding patients require massive transfusion. A new scoring system is developed to identify patients requiring massive transfusion with high accuracy.

Severe anemia associated with transient ischemic attacks involving vertebrobasilar circulation.

Transient ischemic attack is one of the most common causes of transient neurologic deficit. Anemic hypoxia results from reduced hemoglobin content with normal arterial oxygen tension and saturation. Anemic hypoxia caused by blood loss or hemolysis has not been considered as an independent factor leading to significant neurologic problems because cerebral homeostasis adjusted by the physiologic regulation in cerebral hemodynamics and oxygenation would meet the brain oxygen requirement in most circumstances even with profound anemia. We report a case of severe anemia associated with transient ischemic attack involving vertebrobasilar circulation.

Acute pancreatitis caused by severe glyphosate-surfactant oral intoxication.

Glyphosate-surfactant is used extensively as a nonselective herbicide. Suicidal attempts with glyphosate-surfactant herbicide (GlySH) has been encountered with increasing frequency. The effect of GlySH intoxication often involves multiple systems. We report a case of a severely intoxicated man who developed chemical pneumonitis and respiratory failure after suicidal ingestion of GlySH. Acute pancreatitis, which was never covered by any previous case reports, developed in the first day, and the symptom persisted for 10 days during hospitalization.

The association between red blood cell transfusion and outcomes in patients with upper gastrointestinal bleeding.

BACKGROUND: The benefits of transfusion for acute upper gastrointestinal bleeding (UGIB) have not been well established; however, previous studies suggest that transfusion is associated with adverse outcomes. We performed an observational study using a 10-year database to analyze the association between red blood cell (RBC) transfusion and outcomes in patients with UGIB in the emergency department (ED). METHOD AND FINDINGS: All adult patients with UGIB were identified through diagnostic codes. Hospital mortality was the primary outcome; further bleeding was the secondary outcome. Logistic regression, propensity analyses, and conditional logistic regression were performed to determine factors associated with outcomes. Of 59,188 enrolled patients, 31.6% (n = 18,705) received RBC transfusions within 24 h following presentation to the ED. Hospital mortality was noted in 3.9 and 10.6% of the patients in the non-RBC transfusion and RBC transfusion groups, respectively (P < 0.001). RBC transfusion was associated with increased mortality risk (unadjusted odds ratio (OR) 2.95, 95% confidence interval (CI) 2.75-3.16; P < 0.001) among all patients and in the propensity-matched cohort (unadjusted OR 1.55, 95% CI 1.39-1.72; P < 0.001). Further bleeding was noted in 5.6 and 33.8% of the patients in the non-RBC transfusion and RBC transfusion groups, respectively (P < 0.001). RBC transfusion was associated with increased risk of further bleeding (unadjusted OR 8.60, 95% CI 8.16-9.06; P < 0.001) among all patients and in the propensity-matched cohort (unadjusted OR 2.58, 95% CI 2.37-2.79; P < 0.001). CONCLUSION: RBC transfusion was significantly associated with increased rates of hospital mortality and further bleeding in patients with UGIB. Although our findings have strengths, these results are not generalizable to all patients presenting with UGIB, especially patients presenting with exsanguinating bleeding. Additional prospective trials to guide optimal transfusion strategies in UGIB patients are needed.

Effects of fine particulate matter and its constituents on emergency room visits for asthma in southern Taiwan during 2008-2010: a population-based study.

This population-based study evaluated the short-term association between fine particulate matter (PM2.5) concentrations and its constituents and hospital emergency room visits (ERVs) for asthma in southern Taiwan during the period 2008-2010. Data on hospital ERVs for asthma and ambient PM2.5 levels and its constituents were obtained from the National Health Insurance Research database and the Environmental Protection Administration, respectively. The quasi-Poisson generalized additive model was used to explore the associations between PM2.5 and hospital ERVs for asthma. During the study period, the average daily number of ERVs for asthma and mean 24-h average level of PM2.5 was 20.0 and 39.4 µg m-3, respectively. The estimated effects of PM2.5 on asthma ERVs fluctuated with increasing tendencies after adjusting for O3 and attenuating tendencies after adjusting for NO2, SO2, and CO. Children were more susceptible than other age groups to the effects of PM2.5 exposure on asthma ERVs, with the relative risks (RRs) for every 10 µg m-3 increase in PM2.5 being 1.016 [95% confidence interval (CI) = 1.002-1.030] and 1.018 (95% CI = 1.002-1.034), respectively, at a lag 0 day (i.e., no lag days) and lag 0-1 days. The effect of PM2.5 concentrations on asthma ERVs was similar in male and female. Furthermore, asthma ERVs was significantly associated with concentrations of nitrate (NO3-), with the RR for each 1 µg m-3 increase in NO3- concentrations being 1.004 (95% CI = 1.001-1.007) at lag 0 day. In conclusion, both PM2.5 concentrations and its chemical constituents are associated with ERVs for asthma; moreover, children were more susceptible to the effects of PM2.5 in southern Taiwan. PM2.5 constituent, nitrate, is more closely related to ERVs for asthma.

The association between hypertension and traumatic intracranial haemorrhage.

BACKGROUND: Control of blood pressure is considered essential in the management of trauma patients. In patients with head injuries, both hypotension and hypertension are associated with poor outcomes. The present study was undertaken to ascertain whether hypertension at emergency triage is associated with traumatic intracranial haemorrhage. METHODS: From September 2012 to August 2013, data were collected prospectively for patients who presented with head injury and who received a brain CT examination at a university hospital. Factors associated with intracranial haemorrhage were identified, and logistic regression analysis was used to examine the association between hypertension at emergency department triage and traumatic brain haemorrhage. RESULTS: Of a total of 1457 patients enrolled in this study, 252 (17.3%) experienced traumatic intracranial haemorrhage. After controlling for factors associated with traumatic intracranial haemorrhage, an increased risk of intracranial haemorrhage following an initial brain CT scan was identified for patients presenting initially with a systolic blood pressure ≥ 180 mm Hg (odds ratio, 1.80; 95% confidence interval, 1.20-2.71, compared with those with 90-139 mm Hg). CONCLUSION: The presence of hypertension at emergency triage is associated with traumatic intracranial haemorrhage.
