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.

Standard operating procedure changed pre-hospital critical care anaesthesiologists' behaviour: a quality control study.
The ability of standard operating procedures to improve pre-hospital critical care by changing pre-hospital physician behaviour is uncertain. We report data from a prospective quality control study of the effect on pre-hospital critical care anaesthesiologists' behaviour of implementing a standard operating procedure for pre-hospital controlled ventilation. ⋯ We have shown that the implementation of a standard operating procedure for pre-hospital controlled ventilation can significantly change pre-hospital critical care anaesthesiologists' behaviour.

Comparative StudySuperimposed traumatic brain injury modulates vasomotor responses in third-order vessels after hemorrhagic shock.
Traumatic brain injury (TBI) and hemorrhagic shock (HS) are the leading causes of death in trauma. Recent studies suggest that TBI may influence physiological responses to acute blood loss. This study was designed to assess to what extent superimposed TBI may modulate physiologic vasomotor responses in third-order blood vessels in the context of HS. ⋯ Superimposed TBI modulated arteriolar and venular responses to HS in third-order vessels in a spinotrapezius muscle preparation. Further research is necessary to precisely define the role of TBI on the microcirculation in tissues vulnerable to HS.

Eubaric hyperoxia: controversies in the management of acute traumatic brain injury.
Controversy exists on the role of hyperoxia in major trauma with brain injury. Hyperoxia on arterial blood gas has been associated with acute lung injury and pulmonary complications, impacting clinical outcome. The hyperoxia could be reflective of the physiological interventions following major systemic trauma. ⋯ The risk of low brain oxygen is most acute in the first 24 to 48 hours after injury. The administration of a high fraction of inspired oxygen (0.6 to 1.0) in the emergency room may be justifiable until ICU admission for the placement of invasive neurocritical care monitoring systems. Thereafter, fraction of inspired oxygen levels need to be careful titrated to prevent low brain oxygen levels.
