    Background: Thrombocytopenia has been considered a relative or even absolute contraindication to neuraxial techniques due to the risk of epidural hematoma. There is limited literature to estimate the risk of epidural hematoma in thrombocytopenic parturients. The authors reviewed a large perioperative database and performed a systematic review to further define the risk of epidural hematoma requiring surgical decompression in this population. Read More

    Prognostication of traumatic brain injury outcomes in older trauma patients: A novel risk assessment tool based on initial cranial CT findings.
    Int J Crit Illn Inj Sci 2017 Jan-Mar;7(1):23-31
    Neurosurgery Associates, St. Luke's University Health Network, Bethlehem, Pennsylvania, USA.
    Introduction: Advanced age has been traditionally associated with worse traumatic brain injury (TBI) outcomes. Although prompt neurosurgical intervention (NSI, craniotomy or craniectomy) may be life-saving in the older trauma patient, it does not guarantee survival and/or return to preinjury functional status. The aim of this study was to determine whether a simple score, based entirely on the initial cranial computed tomography (CCT) is predictive of the need for NSI and key outcome measures (e.

    Subdural Thoracolumbar Spine Hematoma after Spinal Anesthesia: A Rare Occurrence and Literature Review of Spinal Hematomas after Spinal Anesthesia.
    Cureus 2017 Feb 16;9(2):e1032. Epub 2017 Feb 16.
    Seattle Science Foundation.
    Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas.

    Traumatic Cervical Nerve Root Avulsion with Pseudomeningocele Formation.
    Cureus 2017 Feb 14;9(2):e1028. Epub 2017 Feb 14.
    Department of Radiology, Baylor University Medical Center.
    Cervical nerve root avulsion is a well-documented result of motor vehicle collision (MVC), especially when occurring at high velocities. These avulsions are commonly traction injuries of nerve roots that may be accompanied by a tear in the meninges through the vertebral foramina with associated collections of cerebrospinal fluid (CSF), thereby resulting in a pseudomeningocele. We present a case of a 19-year-old male who experienced an MVC and was brought to the emergency department (ED) with right arm paralysis and other injuries. Read More

    Preliminary study on the automated skull fracture detection in CT images using black-hat transform.
    Conf Proc IEEE Eng Med Biol Soc 2016 Aug;2016:6437-6440
    Linear skull fracture, following head trauma, may reach major blood vessels, such as the middle meningeal artery or sinus venosus, and may cause epidural hematoma. However, hematoma is likely to be missed in the initial interpretation because it spreads only gradually. In addition, the fracture lines that run along the scan slice plane are often missed during initial interpretation. Read More

    Department of Anesthesiology and Pain Medicine, University of Washington, Box 356540, Seattle, WA, 98195-6540, USA.
    Background: Malpractice claims that arise during the perioperative care of patients receiving orthopaedic procedures will frequently involve both orthopaedic surgeons and anesthesiologists. The Anesthesia Closed Claims database contains anesthesia malpractice claim data that can be used to investigate patient safety events arising during the care of orthopaedic patients and can provide insight into the medicolegal liability shared by the two specialties.

    Questions/purposes: (1) How do orthopaedic anesthetic malpractice claims differ from other anesthesia claims with regard to patient and case characteristics, common events and injuries, and liability profile? (2) What are the characteristics of patients who had neuraxial hematomas after spinal and epidural anesthesia for orthopaedic procedures? (3) What are the characteristics of patients who had orthopaedic anesthesia malpractice claims for central ischemic neurologic injury occurring during shoulder surgery in the beach chair position? (4) What are the characteristics of patients who had malpractice claims for respiratory depression and respiratory arrests in the postoperative period?

    Methods: The Anesthesia Closed Claims Project database was the source of data for this study. Read More
