A novel approach to assess hemorrhagic shock severity using the arterially-determined left ventricular isovolumic contraction period.
In conclusion, ventilation-induced preload variation principally affects the arterially determined isovolumic contraction period (AIC). Moreover, AIC can be determined solely from the arterial pressure waveform, whereas PEP also requires ECG measurement. Importantly, AIC determined from either the carotid or aortic pressure waveform are interchangeable suggesting that, in contrast to PEP, AIC may be site independent.

Out-of-hospital emergency medicine in Germany, Austria and Switzerland : Randomized prospective studies from 1990 to 2012.
CONCLUSION: A significant increase or decrease in the number of prospective randomized clinical trials in the out-of-hospital setting could not be found in German speaking countries despite the fact that the absolute numbers of studies had increased. Only about one prospective, randomized clinical trial with an emergency medicine core tracer diagnosis originated from Germany, Austria and Switzerland per year.

Patient with acute renal injury presenting dabigatran overdose: Hemodialysis for surgery.
We report a case of an 80-year-old man presenting hemorrhage with dabigatran overdose caused by obstructive acute renal failure. Before nephrostomy, several hemodialysis sessions were necessary to remove dabigatran probably because of its large volume of distribution. PMID: 24378048 [PubMed - as supplied by publisher]

Central venous oxygen saturation and carbon dioxide gap as resuscitation targets in a hemorrhagic shock
ConclusionsIn this SV‐guided bleeding and fluid resuscitation model, both ScvO2 and dCO2 correlated well with changes in SV, but only the dCO2 returned to its baseline, normal value, while ScvO2 remained significantly lower than at baseline. These results suggest that dCO2 may be a good hemodynamic endpoint of resuscitation, while ScvO2 is not strictly a hemodynamic parameter, but rather an indicator of the balance between oxygen delivery and consumption.

Clinical neuroprotection and secondary neuronal injury mechanisms
Abstract: Multiple disease processes can ultimately lead to cerebral injury, a common cause of both severe morbidity and mortality in patients of all age groups. Cerebral injury is seen in a variety of both medical and surgical conditions, including stroke, subarachnoid haemorrhage, central nervous system infection, epilepsy, post cardiac arrest and, of course, traumatic brain injury.Although the primary damage to brain tissue may be irreversible, aggressive early physiological, pharmacological and surgical interventions may limit the ensuing secondary brain injury caused by ongoing ischaemia, and reduce the risk of severe...

Red blood cell transfusion in neurosurgical patients
Purpose of reviewAnemia is common in neurosurgical patients, and is associated with secondary brain injury. Although recent studies in critically ill patients have shifted practice toward more restrictive red blood cell (RBC) transfusion strategies, the evidence for restrictive versus liberal transfusion strategies in neurosurgical patients has been controversial. In this article, we review recent studies that highlight issues in RBC transfusion in neurosurgical patients. Recent findingsRecent observational, retrospective studies in patients with traumatic brain injury, subarachnoid hemorrhage, and intracranial hemorrhage ...

Postoperative ICU management of patients after subarachnoid hemorrhage
This article reviews recent advances in the postoperative ICU management of patients after subarachnoid hemorrhage (SAH), especially with regards to hemodynamic management, methods of improving neurological outcomes, and management of cardiac and pulmonary complications. Recent findingsSeveral hemodynamic monitors and parameters may be useful for guiding volume therapy, including cardiac output, stroke volume variation monitoring, and global end-diastolic volume index. Early goal-directed hemodynamic therapy after SAH has recently been shown to improve clinical outcomes in patients with a poor clinical grade or coexisting ...

Impact of epinephrine and norepinephrine on two dynamic indices in a porcine hemorrhagic shock model
BACKGROUNDPulse pressure variations (PPVs) and stroke volume variations (SVVs) are dynamic indices for predicting fluid responsiveness in intensive care unit patients. These hemodynamic markers underscore Frank-Starling law by which volume expansion increases cardiac output (CO). The aim of the present study was to evaluate the impact of the administration of catecholamines on PPV, SVV, and inferior vena cava flow (IVCF). METHODSIn this prospective, physiologic, animal study, hemodynamic parameters were measured in deeply sedated and mechanically ventilated pigs. Systemic hemodynamic and pressure-volume loops obtained by i...
