ABSTRACTBackground:Determining the appropriate disposition of emergency department (ED) syncope patients is challenging. Previously developed decision tools have poor diagnostic test characteristics and methodological flaws in their derivation that preclude their use. We sought to develop a scale to risk-stratify adult ED syncope patients at risk for serious adverse events (SAEs) within 30 days. ⋯ The final score calculated by addition of the individual scores for each variable (range 0-10) was found to accurately stratify patients into low risk (score < 1, 0% SAE risk), moderate risk (score 1, 3.7% SAE risk), or high risk (score > 1, ≥ 10% SAE risk). Conclusion:We derived a risk scale that accurately predicts SAEs within 30 days in ED syncope patients. If validated, this will be a potentially useful clinical decision tool for emergency physicians, may allow judicious use of health care resources, and may improve patient care and safety.

ReviewConfusion with cerebral perfusion pressure in a literature review of current guidelines and survey of clinical practise.
Cerebral perfusion pressure (CPP) is defined as the difference between the mean arterial pressure (MAP) and the intracranial pressure (ICP). However, since patients with traumatic brain injury (TBI) are usually treated with head elevation, the recorded CPP values depends on the zero level used for calibration of the arterial blood pressure. Although international guidelines suggest that target values of optimal CPP are within the range of 50 - 70 mmHg in patients with TBI, the calibration of blood pressure, which directly influences CPP, is not described in the guidelines.The aim of this study was to review the literature used to support the CPP recommendations from the Brain Trauma Foundation, and to survey common clinical practice with respect to MAP, CPP targets and head elevation in European centres treating TBI patients. ⋯ The evidence behind the recommended CPP thresholds shows no consistency on how blood pressure is calibrated and clinical practice for MAP measurements and CPP target values seems to be highly variable. Until a consensus is reached on how to measure CPP, confusion will prevail.

Traumatic Spinal Cord Injury (TSCI) is a condition where the neural elements suffer acute trauma, resulting in short-term or permanent sensory and motor problems. An understanding the underlying structural and functional biological repairs of the TSCI mechanisms has intensely increased over the last two decades. However, compared with the other fields in medicine, the present degree of treatment and care for TSCI are quite unsatisfactory. ⋯ However, research on TSCI has been very limited. Therefore, studies on the long-term incidence of TSCI in Saudi Arabia are vital and most essential to identify the high-risk groups, create awareness, establish trends, predict the needs, and thus contribute to effective health care planning of this condition. In this review, we discuss various aspects of TSCI in Saudi Arabia from the available literature.

ABSTRACTObjective:Despite evidence that patients suffering major traumatic injuries have improved outcomes when cared for within an organized system, the extent of trauma system development in Canada is limited. We sought to compile a detailed inventory of trauma systems in Canada as a first step toward identifying opportunities for improving access to trauma care. Methods:We distributed a nationwide online and mail survey to stakeholders intended to evaluate the extent of implementation of specific trauma system components. ⋯ Conclusion:There is significant variability in the extent of trauma system development in Canada. Although all provinces have designated trauma centres, opportunities exist in many systems to implement additional components to improve the inclusiveness of care. In future work, we intend to quantify the strength of the relationship between different trauma system components and access to definitive trauma care.

ABSTRACTObjectives:Computed tomography (CT) use is increasing in the emergency department (ED). Many physicians are concerned about exposing patients to radiation from CT scanning, but estimates of radiation doses vary. This study's objective was to determine the radiation doses from CT scanning for common indications in a Canadian ED using modern multidetector CT scanners. ⋯ Mean doses for the most common indications were as follows: simple head, 2.9 mSv; cervical spine, 5.7 mSv; complex head, 9.3 mSv; CT pulmonary angiogram, 11.2 mSv; abdomen (nontraumatic abdominal pain), 15.4 mSv; and abdomen (renal colic), 9.8 mSv. Conclusions:Approximately one in seven ED patients had a CT scan. Emergency physicians should be aware of typical radiation doses for the studies they order and how the dose varies by protocol and indication.
