Survival and Hemodynamics During Pediatric Cardiopulmonary Resuscitation for Bradycardia and Poor Perfusion Versus Pulseless Cardiac Arrest
The objective of this study was to compare survival outcomes and intra-arrest arterial blood pressures between children receiving cardiopulmonary resuscitation for bradycardia and poor perfusion and those with pulseless cardiac arrests. Design: Prospective, multicenter observational study. Setting: PICUs and cardiac ICUs of the Collaborative Pediatric Critical Care Research Network. Patients: Children (

Transcranial Doppler Ultrasound During Critical Illness in Children: Survey of Practices in Pediatric Neurocritical Care Centers*
Conclusions: At least 27 pediatric neurocritical care centers use transcranial Doppler during clinical care. In the majority of centers, studies are performed and interpreted by credentialed personnel, and findings are used to guide clinical management. Further studies are needed to standardize these practices.

Acute Care Clinical Indicators Associated With Discharge Outcomes in Children With Severe Traumatic Brain Injury*
Conclusions: Acute care clinical indicators of adherence to the Pediatric Guidelines were associated with significantly higher discharge survival and improved discharge Glasgow Outcome Scale. Some indicators were protective, regardless of treatment location, suggesting the need for an interdisciplinary approach to the care of children with severe traumatic brain injury.

Intracranial and Cerebral Perfusion Pressure Thresholds Associated With Inhospital Mortality Across Pediatric Neurocritical Care*
Objectives: Targets for treatment of raised intracranial pressure or decreased cerebral perfusion pressure in pediatric neurocritical care are not well defined. Current pediatric guidelines, based on traumatic brain injury, suggest an intracranial pressure target of less than 20 mm Hg and cerebral perfusion pressure minimum of 40–50 mm Hg, with possible age dependence of cerebral perfusion pressure. We sought to define intracranial pressure and cerebral perfusion pressure thresholds associated with inhospital mortality across a large single-center pediatric neurocritical care cohort. Design: Retrospective ...

Age-Based Percentiles of Measured Mean Arterial Pressure in Pediatric Patients in a Hospital Setting
Conclusions: This is the first study reporting age-specific quantiles of measured mean arterial pressure in children in a hospital setting. The percentile curves may guide care in illnesses when perfusion pressure is critical and serve as parameter for bedside and electronic record-based response to clinical change. Future work to correlate threshold mean arterial pressure values with outcomes would be feasible based on quantile curves.

Variability in the Hemodynamic Response to Fluid Bolus in Pediatric Septic Shock
CONCLUSIONS: The hemodynamic response to fluid bolus in pediatric septic shock was variable and unpredictable. We failed to find a relationship between mean arterial pressure and cardiac index changes. The adverse effects of fluid bolus extended beyond fluid overload and, in some cases, was associated with reduced mean arterial pressure, perfusion pressures and higher vasoactive support. Mean arterial pressure-nonresponders had increased mortality. The response to the initial fluid bolus may be helpful to understand each patient’s individualized physiologic response and guide continued hemodynamic management.

Fentanyl and Midazolam Are Ineffective in Reducing Episodic Intracranial Hypertension in Severe Pediatric Traumatic Brain Injury*
Conclusions: Bolus dosing of fentanyl and midazolam fails to reduce the intracranial hypertension burden when administered for episodic intracranial hypertension. Paradoxically, we observed an overall increase in intracranial hypertension burden following drug administration, even after accounting for within-subject effects and time after injury. Future work is needed to confirm these findings in a prospective study design.

Cerebral Hemodynamic Profile in Ischemic and Hemorrhagic Brain Injury Acquired During Pediatric Extracorporeal Membrane Oxygenation
Conclusions: This study outlines distinct differences in underlying cerebral hemodynamics associated with ischemic and hemorrhagic brain injury acquired during extracorporeal membrane oxygenation. Real-time monitoring of cerebral hemodynamics in patients acquiring brain injury during extracorporeal membrane oxygenation can help optimize their management.

Unrecognized catatonia as a cause for delayed weaning in Intensive Care Unit
Rupesh Gupta, Saurabh Saigal, Rajnish Joshi, Praveen Tagore, Nirendra Rai, Krishna PrasadIndian Journal of Critical Care Medicine 2015 19(11):693-694The cause of altered sensorium in critical care settings includes metabolic derangements, drug and toxin overdose, central nervous system infections, neurodegenerative disorders, vascular events, hypo-perfusion states, and septic encephalopathy. Here, we present a case of an elderly woman who presented to us with altered sensorium with respiratory failure requiring mechanical ventilation. Her metabolic parameters, imaging, and cerebrospinal fluid study were all normal despite ...

Critical Cerebral Perfusion Pressure at High Intracranial Pressure Measured by Induced Cerebrovascular and Intracranial Pressure Reactivity
Objectives: The lower limit of cerebral blood flow autoregulation is the critical cerebral perfusion pressure at which cerebral blood flow begins to fall. It is important that cerebral perfusion pressure be maintained above this level to ensure adequate cerebral blood flow, especially in patients with high intracranial pressure. However, the critical cerebral perfusion pressure of 50 mm Hg, obtained by decreasing mean arterial pressure, differs from the value of 30 mm Hg, obtained by increasing intracranial pressure, which we previously showed was due to microvascular shunt flow maintenance of a falsely high cerebral blood...
