Rapid induction of hypothermia early after resuscitation can be an effective strategy against post-cardiac arrest syndrome (PCAS). Preliminary data suggested that continuous renal replacement therapy (CRRT) might be an efficient method to rapidly induce hypothermia. In this study, we investigated the efficacy of cooling induced by CRRT and its effects on the outcomes of PCAS in a porcine model.Thirty-two male domestic pigs weighing 36 ± 2 kg were randomized into 4 groups: sham control (n = 5), normothermia (n = 9), surface cooling (SC, n = 9), and CRRT (n = 9)...

Cardiogenic global brain hypoxia-ischemia is a devastating medical problem that is associated with unfavorable neurologic outcomes. Low dose hydrogen gas (up to 2.9%) has been shown to be neuroprotective in a variety of brain diseases. In the present study, we investigated the protective effect of water by electrolysis-derived high concentration hydrogen gas (60%) in a rat model of asphyxia induced-cardiac arrest and global brain hypoxia-ischemia. High concentration hydrogen gas was either administered starting 1 hour prior to cardiac arrest for 1 hour and starting 1 hour post-resuscitation for 1 hour (pre- & post-treatment) or starting 1 hour post-resuscitation for 2 hours (post-treatment)...

Background: Non-invasive, easy-to-use bedside tools to estimate prognosis in unresponsive patients with postanoxic brain injury are needed. We assessed the usefulness of otoacoustic emissions as outcome markers after cardiac arrest. Methods: Distortion product otoacoustic emissions (DPOAE) and transient evoked otoacoustic emissions (TEOAE) were measured in cardiac arrest patients whose prognosis was deemed to be poor following standard neurological assessment ( n = 10). Ten patients with myocardial infarction without prior loss of consciousness served as controls...

REVIEW
Amy C Walker, Nicholas J Johnson
The post-cardiac arrest syndrome is a highly inflammatory state characterized by organ dysfunction, systemic ischemia and reperfusion injury, and persistent precipitating pathology. Early critical care should focus on identifying and treating arrest etiology and minimizing further injury to the brain and other organs by optimizing perfusion, oxygenation, ventilation, and temperature. Patients should be treated with targeted temperature management, although the exact temperature goal is not clear. No earlier than 72 hours after rewarming, prognostication using a multimodal approach should inform discussions with families regarding likely neurologic outcome...

Imaging diagnosis of brain death is performed with either four-vessel cerebral angiography or radionuclide cerebral blood flow studies. Unfortunately, timely performance of either study at a critically ill period is not only cumbersome but not feasible in many cases. We present a case of a 6-month-old male three hours status post-cardiac arrest of unknown etiology who underwent contrast-enhanced ultrasound (CEUS) for diagnosis of near absent perfusion, or near brain death. The patient passed away 30 minutes after the exam and clinical diagnosis of brain death was confirmed...

This study aimed to evaluate the usefulness of near-infrared time-resolved spectroscopy (TRS) for the monitoring of post-resuscitation encephalopathy. Cardiac arrest (CA) was induced in pigs by electrical stimuli; then, return of spontaneous circulation (ROSC) was achieved by direct current. The changes in cerebral oxygenation were analyzed by two methods: (1) the time-independent calculation based on the modified Beer-Lambert law (MBL), and (2) the curve-fitting method based on the photon diffusion theory (DT)...

Transient global brain ischemia, induced by cardiac arrest and resuscitation, results in reperfusion injury leading to delayed selective neuronal cell loss and post-resuscitation mortality. This study determined the effects of post-resuscitation hypotension and hypothermia on long-term survival following cardiac arrest and resuscitation. The capillary density was also determined. Based on the mean arterial blood pressure (MABP) at 1 h of recovery, the normotension group (MABP 80-120 mmHg) and hypotension group (MABP <80 mmHg) were defined...

INTRODUCTION: Pentobarbital (PB) is a euthanasia drug in doses of 2 to 10 grams, causing death within 15-30 minutes. We report a case of recovery from lethal pentobarbital deliberate self-poisoning with confirmatory serum drug concentrations. CASE REPORT: A 45-year-old male purchased 20 grams of PB powder over the Internet. He ingested this powder and then alerted his mother 10 minutes later. She found him unresponsive and commenced cardiopulmonary resuscitation (CPR)...

In many forensic cases, the existence of a traumatic brain injury (TBI) is an essential factor, and the determination of the survival time is nearly as important as the determination of whether or not a trauma exists. Since it is known that glucose uptake increases in injured brain cells in order to perpetuate the neuronal integrity, this study focuses on the pathomechanism of brain glucose supply via sodium/glucose cotransporters 1 and 2 (SGLT1, SGLT2) following traumatization. Human cerebrum tissue of male and female individuals who died following TBI was taken from the contusional and contralateral regions, as well as from individuals deceased due to cardiac arrest (control group)...

BACKGROUND AND OBJECTIVE: Intraoperative rupture of a cerebral aneurysm during neurosurgery can be a devastating event that increases perioperative morbidity and mortality. Rapid ventricular pacing (RVP) is a technique to obtain flow arrest for short periods of time during dissection or rupture of the aneurysm. The objective of this study was to evaluate the neurological and cardiac effects of repetitive periods of RVP during cerebrovascular surgery. METHODS: Data from patients who underwent repetitive RVP during craniotomy for cerebrovascular disorders were retrospectively analyzed from a single-center medical records database (Cegeka Medical Health Care Systems)...

PURPOSE: The density ratio of gray matter (GM) to white matter (WM) on brain computed tomography (CT) (gray-to-white matter ratio, GWR) helps predict the prognosis of comatose patients after cardiac arrest. However, Hounsfield units (HU) are not an absolute value and can change based on imaging parameters and CT scanners. We compared the density of brain GM and WM and the GWR by using images scanned with different types of CT machines. METHOD: 102 patients with normal readings who were scanned using three types of CT scanners were included in the study...

Background: Neuroprotection studies are generally unable to demonstrate efficacy in humans. Our specific hypothesis is that multiple pathophysiologic pathways, of variable importance, contribute to ischemic brain damage. As a corollary to this, we discuss the broad hypothesis that a multifaceted approach will improve the probability of efficacious neuroprotection. But to properly test this hypothesis the nature and importance of the multiple contributing pathways needs elucidation. Our aim is to demonstrate, using functional genomics, in human cardiac surgery procedures associated with cerebral ischemia, that the pathogenesis of perioperative human ischemic brain damage involves the function of multiple variably weighted proteins involving several pathways...
