Evaluation of hematological markers in minor head trauma in the emergency room

Introduction

A rule exists regarding the use of computed tomography (CT) for patients presenting to the emergency department with head trauma and a Glasgow coma score (GCS) of 15; however, it can be difficult to make this decision due to overcrowded emergency rooms or exaggerated patients complaints. We evaluated patients who presented to the emergency room with minor head trauma, and we aimed to investigate the relationship between brain pathology on CT and hematological markers in order to find markers that help us identify brain pathology in patients with a GCS of 15.

Methods

This retrospective study included 100 patients with pathologies present on their CT scans and a control group consisting of 100 patients with a normal CT. All data obtained from this study were recorded and evaluated using “Statistical Package for Social Sciences for Windows 20” program. Parametric tests (independent samples test) were used with normally distributed data, while non-parametric tests (Mann–Whitney U test) were used with non-normally distributed data. A p ≤ 0.05 was considered significant.

Finding

When we divided the cases into two groups based on the presence of pathologies on CT scan, we determined that there were significant differences between the groups in terms of white blood cell (WBC), hemoglobin (Hb), mean platelet volume (MPV), neutrophil (neu), troponin T, neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR). When differentiating the patients that had brain pathologies on CT scan from patients that had normal CT scans, the troponin T cut-off value of 6.16 lead to 90 % specificity, and setting the NLR cut-off value at 4.29 resulted in a specificity of 90 %.

Conclusion

MPV, NLR, and troponin T can be used as parameters that indicate brain pathologies on CT scans of patients presenting to the emergency department with isolated minor head trauma and GCS of 15 when the necessity of a CT scan is otherwise unclear.

     

The Limited Role of Ultrasound in the Diagnostic Process of Colonic Diverticulitis

Background

Diverticulitis is commonly diagnosed using ultrasound (US), followed by computed tomography (CT). Our aim was to determine the diagnostic accuracy of US compared with CT for patients with uncomplicated and complicated diverticulitis.

Methods

We reviewed medical records of 232 patients admitted with diverticulitis via the emergency department between January 2009 and January 2011. Patients who had undergone US and a CT scan were identified and further analyzed.

Results

A total of 123 patients underwent an US and a CT scan. In 78/94 patients with uncomplicated diverticulitis, results of US and CT scan were compatible (83 %); in 6 of the remaining 29 patients both modalities showed a complicated diverticulitis (21 %). US misdiagnosed 17 % of patients with uncomplicated diverticulitis and 79 % with complicated diverticulitis.

Conclusions

US is insufficient for diagnosing a complicated diverticulitis. Missing a complicated diverticulitis can have important clinical implications, and if diverticulitis is suspected, we suggest obtaining a CT scan to confirm diagnosis and to exclude complications.     

Glasgow Coma Scale score at intensive care unit discharge predicts the 1-year outcome of patients with severe traumatic brain injury

Objective

To analyse the association between the Glasgow Coma Scale (GCS) score at intensive care unit (ICU) discharge and the 1-year outcome of patients with severe traumatic brain injury (TBI).

Design

Retrospective analysis of prospectively collected observational data.

Patients

Between 01/2001 and 12/2005, 13 European centres enrolled 1,172 patients with severe TBI. Data on accident, treatment and outcomes were collected. According to the GCS score at ICU discharge, survivors were classified into four groups: GCS scores 3–6, 7–9, 10–12 and 13–15. Using the Glasgow Outcome Scale (GOS), 1-year outcomes were classified as “favourable” (scores 5, 4) or “unfavourable” (scores <4). Factors that may have contributed to outcomes were compared between groups and for favourable versus unfavourable outcomes within each group.

Main results

Of the 538 patients analysed, 308 (57 %) had GCS scores 13–15, 101 (19 %) had scores 10–12, 46 (9 %) had scores 7–9 and 83 (15 %) had scores 3–6 at ICU discharge. Factors significantly associated with these GCS scores included age, severity of trauma, neurological status (GCS, pupils) at admission and patency of the basal cisterns on the first computed tomography (CT) scan. Favourable outcome was achieved in 74 % of all patients; the rates were significantly different between GCS groups (93, 83, 37 and 10 %, respectively). Within each of the GCS groups, significant differences regarding age and trauma severity were found between patients with favourable versus unfavourable outcomes; neurological status at admission and CT findings were not relevant.

Conclusion

The GCS score at ICU discharge is a good predictor of 1-year outcome. Patients with a GCS score <10 at ICU discharge have a poor chance of favourable outcome.     

Prehospital care in patients with severe traumatic brain injury: does the level of prehospital care influence mortality?

Introduction and purpose

The controversy between the “scoop and run” versus the “stay and play” approach in severely injured trauma patients has been an ongoing issue for decades. The present study was undertaken to investigate whether changes in prehospital care for patients with severe traumatic brain injury in the Netherlands have improved outcome.

Methods

In this retrospective study, files (n = 60) were analyzed from a prospectively collected database including all patients admitted to one of six hospitals in the Limburg region in the Netherlands with a Glasgow Coma Scale (GCS) score ≤8 on admittance over the period from January 2006 to December 2008. All patients had traumatic brain damage proven on computed tomography (CT) or magnetic resonance imaging (MRI). Relevant prehospital and clinical data from the present cohort were compared to data from a similar study (n = 30) conducted 20 years ago. The primary outcome assessed was mortality.

Results

The two study groups had similar characteristics with regard to the GCS score. In the historic cohort, Basic Life Support (BLS) and the “scoop and run” approach in patients with major traumatic brain injury was common, with an average time on scene of 7.5 min. Currently, prehospital care is performed mainly on the level of prehospital Advanced Life Support (ALS), with the average time on scene being about four times as long as in the historic cohort. However, the overall mortality rate for the current cohort compared to the historic cohort has not changed.

Conclusion

Despite more on-site ALS in severely head injured patients nowadays compared to the historic cohort, there was no reduction in mortality.     

Prognostic value of arterial blood gas disturbances for in-hospital mortality in pediatric patients with severe traumatic brain injury

Background

The aim of this study was to evaluate the changes of arterial blood gas as a secondary insult in children and young adults suffering from severe traumatic brain injury, and to assess the correlation, if any, with their in-hospital mortality.

Method

In this cross-sectional study, the medical data of all children and adolescents with severe head trauma admitted to the Rasht Poursina Hospital were reviewed between April 2006 and September 2011. Data including age, gender, GCS upon admission, arrival and daily ABG values for the first 3 days, results of brain CT scan, as well as in-hospital mortality rate were collected. A logistic regression model was used to determine the association between acid–base disturbance and in-hospital mortality after adjustment for potential confounding factors.

Result

Of the 108 patients, 75 % were male and 25 % were female; and 31.5 % of them died in the hospital. Univariate analysis showed a significantly higher risk of mortality in patients who developed mixed metabolic acidosis plus respiratory acidosis on their admission day (OR?=?3.94, p?=?0.012). Multiple logistic regression analysis demonstrated that mixed metabolic acidosis plus respiratory acidosis (OR?=?3.81, 95 % CI?=?1.18–12.27, p-value?=?0.025) and GCS (OR?=?0.457, 95 % CI?=?0.31–0.65, p-value?<?0.001) were two significant predictors of mortality, regardless of other confounding variables.

Conclusion

The results of present study show that, in pediatric patients with severe head injuries, initial mixed metabolic acidosis plus respiratory acidosis and GCS are significant predictors of mortality, but other factors after adjustment for potential confounding factors had no prognostic effect.     

Significance of Computed Tomography Finding of Intra-Abdominal Free Fluid Without Solid Organ Injury after Blunt Abdominal Trauma: Time for Laparotomy on Demand

Background

Optimal management of patients with intra-abdominal free fluid found on computed tomography (CT) scan without solid organ injury remains controversial.

Objective

The purpose of this study was to determine the significance of CT scan findings of free fluid in the management of blunt abdominal trauma patients who otherwise have no indications for laparotomy.

Methods

During the 3-year study period, all patients presenting with blunt abdominal trauma who underwent abdominal CT examination were retrospectively reviewed. All hemodynamically stable patients who presented with abdominal free fluid without solid organ injury on CT scan were analyzed for radiological interpretation, clinical management, operative findings, and outcome.

Results

A total of 122 patients were included in the study, 91 % of whom were males. The mean age of the patients was 33 ± 12 years. A total of 34 patients underwent exploratory laparotomy, 31 of whom had therapeutic interventions. Small bowel injuries were found in 12 patients, large bowel injuries in ten, and mesenteric injuries in seven patients. One patient had combined small and large bowel injury, and one had traumatic gangrenous appendix. In the remaining three patients, laparotomy was non-therapeutic. A total of 36 patients had associated pelvic fractures and 33 had multiple lumbar transverse process fractures.

Conclusion

Detection of intra-peritoneal fluid by CT scan is inaccurate for prediction of bowel injury or need for surgery. However, the correlation between CT scan findings and clinical course is important for optimal diagnosis of bowel and mesenteric injuries.     

The prognostic reliability of the Glasgow coma score in traumatic brain injuries: evaluation of MRI data

Purpose

To clarify the predictive power of the Glasgow coma score (GCS) after traumatic brain injury (TBI) and in the context of brain stem lesions.

Methods

In 143 patients who had suffered severe TBI, the GCS was correlated to brain damage as visualized by cranial magnetic resonance imaging (MRI). This technique evaluates the damage to the brain stem in particular. The Brussels coma score (BCS) was also used.

Results

The GCS was not significantly correlated to brain stem lesions when it was only scored at the time of admission. When MRI was not used later on, the GCS showed a poor ability to predict the outcome. After 24 h, and on the day of MRI screening, the GCS was significantly correlated with two parameters: outcome (the higher the GCS, the better the outcome) and the frequency of patients without injuries to the brainstem in MRI (the higher the GCS, the higher this frequency). These correlations were much more evident when the BCS was used. The prognostic power of the GCS was found to vary over time; for example: a GCS of 3 at admission was associated with a favorable prognosis; a GCS of 4 signified a poor prognosis, irrespective of the time point at which the GCS was scored; and the prognostic power of a GCS of 5 deteriorated from the day of the MRI onwards, whereas the prognostic power of a GCS of 6 or 7 varied little over time.

Conclusions

We only recommend the use of the GCS for prognostic evaluation in a multidimensional model. Study protocols should contain additional brain stem function parameters (BCS, pupil condition, MRI).     

Das serologische Protein S100B

Objective

Patients presenting in the emergency department with a mild injury to the head pose a particular challenge due to their high prevalence but low rate of traumatic brain injury. However, missed traumatic brain injuries may result in fatal consequences. Therefore we investigated the diagnostic performance of serological protein S100B measurement in adult patients presenting with mild head injury and a GCS 13-15 to identify traumatic brain injury.

Design and methods

We conducted a systematic review of the literature. Two reviewers screened potential studies for inclusion and independently extracted study data. For all included studies, we applied the QUADAS quality assessment tool for systematic reviews of diagnostic accuracy and abstracted the raw data for every included study. Included studies presented results either in 2x2 contingency tables or provided data allowing their construction.

Results

Of 76 studies identified, 8 met the inclusion criteria. Methodology quality was moderate and all studies fulfilled at least 50% of the QUADAS criteria. Overall, the sensitivity to detect intracranial lesions was 94% (95% CI 88–98%) and specificity was 44% (95% CI 30–58%). The subgroup analysis showed significant differences only between studies with different S100B cutoff values (0.10?μg/l versus >0.10?μg/l). The combined odds ratio was 10.3 (95 CI 4.2–24.9).

Conclusions

Serological protein S100B measurement may be helpful as a screening test to identify patients with higher risk of traumatic brain injury for further diagnostic assessment.     

The arcuate line hernia: operative treatment and a review of the literature

Purpose

An arcuate line hernia (ALH) is a rare diagnosis with no consensus on how to deal with this condition either when symptomatic or when found accidentally. Suggestions for laparoscopic and open operative techniques are given together with a review of the literature and a presentation of three new cases.

Material

The PubMed database was searched for publications on ALH. Identified cases, including three from our department, are reported.

Results

Five males and two females, with a median age of 53 years were identified. Three patients were correctly diagnosed on a preoperative CT scan and the rest at surgery. Two patients had bilateral ALHs and four had other concomitant hernias repaired. Small bowel was present in the hernia in three cases and sigmoid colon in one. In one case, an emergency operation was performed due to bowel incarceration. Five patients had laparoscopic repairs, three with mesh and two without. Two patients, one converted from laparoscopic to open operation, had open mesh repairs. The postoperative course was uneventful in all cases, and no recurrences have been reported at a median follow-up of 6 months.

Conclusions

A laparoscopic approach is recommended for diagnostic purposes, for pre-peritoneal mesh placement and for repair of concomitant hernias in both elective and emergency settings. Highlighting its existence might help general surgeons in interpreting an unusual finding on a CT scan or at operation.     

The prognostic value of plasma Δ-copeptin levels in patients with isolated traumatic brain injury

Purpose

Traumatic brain injury (TBI) is one of the most common causes of death among trauma patients. Earlier prediction of possible poor neurological outcomes, even upon admission to the emergency department, may help to guide treatment. The aim of this prospective study was to assess the predictive value of plasma copeptin levels for early morbidity and mortality in patients with isolated TBI.

Methods

This prospective study comprised 53 patients who were admitted to the emergency department with isolated TBI. Forty-two of these patients (group I) survived at least 1 month after the TBI; the other 11 (group II) did not. Plasma levels of copeptin were measured in these TBI patients at admission and 6 h after trauma, and were compared with those of healthy volunteers (group III).

Results

At admission, the copeptin levels of the TBI patients (groups I and II combined) were not statistically significantly different from those of the control group (III). The copeptin levels 6 h after trauma were also not statistically significantly different from those at admission. Δ-Copeptin levels (the difference between the copeptin level at the 6th hour after trauma and that at admission) were higher in the patients who died within a month of the TBI. Further, Δ-copeptin levels were higher in patients who showed no improvement in the modified Rankin score when compared with patients with an improved modified Rankin score. The best cutoff point for Δ-copeptin was 0.51 ng/ml for predicting mortality and 0.23 ng/ml for predicting improvement in the modified Rankin score.

Conclusions

Plasma Δ-copeptin levels may help physicians predict the prognoses of patients suffering from traumatic brain injury.     

Multislice-Spiral-CT zur Diagnostik beim Polytrauma

Background

In severely injured patients, diagnostic procedures should be as brief as possible. With the use of spiral CT technology, the time required for diagnosis is minimized.

Question

Do severely injured patients benefit when primary diagnostic examinations are completed in less than 30 min? How much time is required for primary emergency department (ED) care and how much in the CT scanner?

Material and methods

Between 31 July 2001 and 31 December 2003, severely injured patients with ISS scores over 16 underwent total body spiral CT scans (Siemens Somatom Volume Zoom Multislice CT) after initial ultrasonography. One hundred patients (M:F=25:75) with an average age of 42 years (range: 3–81 years) were evaluated retrospectively. The average ISS score was 32.8±12 points (range: 17–75 points).

Results

The average time in the ED, prior to CT, was 33±14 min. The CT scans lasted 16±5 min and the total diagnostic time was 48±14 min. Fifty percent of patients were taken immediately to the operating room. The mortality rate in hospital was 13%. The average hospital stay was 30 days, with an average ICU stay of 10 days.

Conclusion

The shorter the time spent in the ED, the shorter the stays in ICU and in total hospitalization were, regardless of injury severity. With structured management and shortening of diagnostic time with spiral CT, the time in the ED was decreased from 85 to 48 min.     

Preoperative serum lactate cannot predict in-hospital mortality after decompressive craniectomy in traumatic brain injury

Purpose

Despite the utility of serum lactate for predicting clinical courses, little information is available on the topic after decompressive craniectomy. This study was conducted to determine the ability of perioperative serum lactate levels to predict in-hospital mortality in traumatic brain-injury patients who received emergency or urgent decompressive craniectomy.

Methods

The medical records of 586 consecutive patients who underwent emergency or urgent decompressive craniectomy due to traumatic brain injuries from January 2007 to December 2014 were retrospectively analyzed. Pre- and intraoperative serum lactate levels and base deficits were obtained from arterial blood gas analysis results.

Results

The overall mortality rate after decompressive craniectomy was 26.1 %. Mean preoperative serum lactate was significantly higher in the non-survivors (P = 0.034) than the survivors but had no significance for predicting in-hospital mortality in the multivariate regression analysis (P = 0.386). Rather, preoperative Glasgow Coma Score was a significant predictor for in-hospital mortality (hazard ratio 0.796, 95 % confidence interval 0.755–0.836, P < 0.001).

Conclusion

Preoperative lactate level is not an independent predictor of in-hospital mortality after decompressive craniectomy in traumatic brain-injury patients.

     

Predicting Hollow Viscus Injury in Blunt Abdominal Trauma with Computed Tomography

Background

Evaluation of blunt abdominal trauma is controversial. Computed tomography (CT) of the abdomen is commonly used but has limitations, especially in excluding hollow viscus injury in the presence of solid organ injury. To determine whether CT reports alone could be used to direct operative treatment in abdominal trauma, this study was undertaken.

Methods

The trauma database at Auckland City Hospital was accessed for patients who had abdominal CT and subsequent laparotomy during a five-year period. The CT scans were reevaluated by a consultant radiologist who was blinded to operative findings. The CT findings were correlated with the operative findings.

Results

Between January 2002 and December 2007, 1,250 patients were evaluated for blunt abdominal injury with CT. A subset of 78 patients underwent laparotomy, and this formed the study group. The sensitivity and specificity of CT scan in predicting hollow viscus injury was 55.33 and 92.06 % respectively. The positive and negative predictive values were 61.53 and 89.23 % respectively. Presence of free fluid in CT scan was sensitive in diagnosing hollow viscus injury (90 %). Specific findings for hollow viscus injuries on CT scan were free intraperitoneal air (93 %), retroperitoneal air (100 %), oral contrast extravasation (100 %), bowel wall defect (98 %), patchy bowel enhancement (97 %), and mesenteric abnormality (94 %).

Conclusions

CT alone cannot be used as a screening tool for hollow viscus injury. The decision to operate in hollow viscus injury has to be based on mechanism of injury and clinical findings together with radiological evidence.     

Der Schockraum – Diagnostik-, Therapie- und Managementzentrale

Background:

In the treatment of the polytraumatized patient ,time is crucial. New technical developments such as multislice CT, which can finish the polytrauma spiral in 90–240 s, shorten the duration of trauma treatment considerably. In the past, CT diagnostics have been used after the initial diagnostics.

Methods:

To obtain the full advantage of the new multislice CT, it is important to put carry out CT diagnostics in the first minutes of clinical care. After the installation of a multislice CT in the emergency room, we developed an algorithm in which CT diagnostics are made in these first minutes.

Results:

The new algorithm was performed on 118 patients. At 8 min (±5,7 SD) after the patient’s arrival CT was started. It was completed 13 min (±8,4 SD) after the arrival of the patient. The time in the emergency room decreased from 87 min to 38 min (±19,1 SD).

Conclusions:

Early CT diagnostics can save time for the trauma patient, with life threading injuries being recognized within minutes.     

Is computed tomography necessary to determine liver injury in pediatric trauma patients with negative ultrasonography?

Purpose

Abdominal trauma is the third most common cause of all trauma-related deaths in children. Liver injury is the second most common, but the most fatal injury associated with abdomen trauma. Because the liver enzymes have high sensitivity and specificity, the use of tomography has been discussed for accurate diagnosis of liver injury.

Methods

Our study was based on retrospective analyses of hemodynamically stabil patients under the age of 18 who were admitted to the emergency department with blunt abdominal trauma.

Results

Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were significantly higher as a result of liver injury. In the patients whose AST and ALT levels were lower than 40 IU/L, no liver injury was observed in the contrast-enhanced computed tomography (CT). No liver injury was detected in the patients with AST levels lower than 100 IU/L. Liver injury was detected with contrast-enhanced CT in only one patient whose ALT level was lower than 100 IU/L, but ultrasonography initially detected liver injury in this patient.

Conclusions

According to our findings, abdominal CT may not be necessary to detect liver injury if the patient has ALT and AST levels below 100 IU/L with a negative abdominal USG at admission and during follow-up.     

Are soft tissue measurements on lateral cervical spine X-rays reliable in the assessment of traumatic injuries?

Introduction

Traumatic neck pain is a common presentation to the emergency department. Lateral plain radiographs remain the primary investigation in the assessment of these injuries. Soft tissue assessment forms an integral component of these radiographs. They can provide information on subtle injuries that may not be obvious. Many methods are used to assess the prevertebral soft tissue shadows. The two more commonly used techniques include the ‘seven at two and two at seven’ rule (method 1) and the ratio of the soft tissues with respect to the vertebral width (method 2).

Aim

To assess which of the above two methods in assessing cervical spine soft tissue shadows on lateral radiographs is more sensitive in the presence of cervical spine injuries.

Methods

A retrospective analysis of consecutive traumatic cervical spine films performed within a busy trauma tertiary centre over a period of 7 months. Patients were divided into two groups: group 1—fractures; group 2—no fractures. The prevertebral soft tissue shadows were measured at referenced points on the lateral cervical spine films with respect to the above two methods and comparisons between the groups were made.

Results

Thirty-nine patients in group 1 were compared to a control group of 60 patients in group 2. Both methods failed to identify any significant differences between the two groups. The sensitivity and specificity for method 1 was 7.6 and 93 %, and for method 2, they were 7.6 and 98 %, respectively.

Conclusion

There is no significant difference between the soft tissue shadows when comparing patients with and without cervical spine fractures on lateral radiographs. Both commonly used measures of soft tissue shadows in clinical practice are insensitive in identifying patients with significant osseous injuries. They, therefore, do not offer any further value in interpreting traumatic cervical spine radiographs. The management of patients with cervical spine trauma in the absence of obvious osseous injury on standard radiographs should warrant a computed tomography (CT) scan if clinically indicated.     

A Year of Fractures: a snapshot analysis of the logistics, problems and outcomes of a hospital-based fracture liaison service

Summary

Our fracture liaison service identifies patients with low trauma fractures, determines the need for osteoporosis therapy and instigates therapy if necessary. We describe the tracking and outcome of 768 patients attending our emergency department over 1 year and discuss the problems we encountered and potential solutions.

Introduction

Osteoporotic fractures result in substantial morbidity, mortality and economic cost, and patients sustaining a first fracture are known to be at higher risk of sustaining future fracture. Treatment of at-risk patients has been shown to assist in prevention of future fracture including hip fracture. We established a “First Fracture Project” to identify and treat these patients in 2003.

Methods

We assessed “A Year of Fractures”: the logistics, outcome and problems in tracking patients presenting to our emergency department with a low trauma fracture by our fracture liaison service, over 1 year from July 2008 to June 2009. Patients were tracked by our osteoporosis nurse and offered assessment, and treatment where necessary.

Results

In 1 year, 768 patients aged 50 or over were identified from emergency department records as attending with a low trauma fracture. About 84 % of patients eventually received assessment. Of the162 patients progressing through the entire process, 74 % had osteoporosis treatment planned and/or commenced.

Conclusions

Our fracture liaison service was effective at identifying most low trauma fracture patients at risk of further fracture and providing access to osteoporosis assessment. There were many difficulties: we outline logistic and practical issues in delivering our service and suggest potential improvements.     

Volume and densities of chronic subdural haematoma obtained from CT imaging as predictors of postoperative recurrence: a prospective study of 107 operated patients

Background

Chronic subdural haematoma (CSDH) is a common entity in neurosurgery with a considerable postoperative recurrence rate. Computerised tomography (CT) scanning remains the most important diagnostic test for this disorder. The aim of this study was to characterise the relationship between the recurrence of CSDH after treatment with burr-hole irrigation and closed-system drainage technique and CT scan features of these lesions to assess whether CT findings can be used to predict recurrence.

Methods

We investigated preoperative and postoperative CT scan features and recurrence rate of 107 consecutive adult surgical cases of CSDH and assessed any relationship with univariate and multivariate regression analyses.

Results

Seventeen patients (15.9 %) experienced recurrence of CSDH. The preoperative haematoma volume, the isodense, hyperdense, laminar and separated CT densities and the residual total haematoma cavity volume on the 1st postoperative day after removal of the drainage were identified as radiological predictors of recurrence. If the preoperative haematoma volume was under 115 ml and the residual total haematoma cavity volume postoperatively was under 80 ml, the probability of no recurrence was very high (94.4 % and 97.4 % respectively).

Conclusions

These findings from CT imaging may help to identify patients at risk for postoperative recurrence.     

Zeitintervalle während und nach Schockraumversorgung

Background

The prognosis of severely injured patients depends on a rapid diagnosis and early initiation of therapeutic procedures.

Material and methods

To that end a total of 6,927 prospectively documented severely injured patients with an Injury Severity Score (ISS) ≥16 from the Trauma Registry of the German Trauma Society (DGU, 2002–2007) were analyzed with respect to time intervals during emergency trauma treatment.

Results

In cases of indicated emergency surgery the average ±time in the emergency department was 42±34 min, in cases of early surgery 75±41 min and in cases of transfer to the intensive care unit (ICU) 83±43 min, respectively. The time from the last diagnostic procedure until the end of emergency treatment was 12 min (emergency surgery), 26 min (early surgery) and 32 min (ICU), respectively. Level I (78 min) and level II (72 min) trauma centres showed similar mean times in the emergency department while level III trauma centres had a mean time of 86 min. According to this analysis no general correlation between shorter duration of emergency trauma care and reduced mortality could be observed.

Conclusion

The duration of time intervals depends on injury severity, treatment after completion of emergency trauma care and the level of the trauma centre. Time management in emergency trauma care can potentially be optimized after completion of the last diagnostic procedure in the emergency room.
