Using a real-time ABCDEF compliance tool to understand the role of bundle elements in mortality and delirium.

Background: ABC-123, a novel Epic electronic medical record real-time score, assigns 0 to 3 points per bundle element to assess ABCDEF bundle compliance. We sought to determine if maximum daily ABC-123 score (ABC-MAX), individual bundle elements, and mobility were associated with mortality and delirium-free/coma-free intensive care unit (DF/CF-ICU) days in critically injured patients.

Methods: We reviewed 6 months of single-center data (demographics, Injury Severity Score [ISS], Abbreviated Injury Scale of the head [AIS-Head] score, ventilator and restraint use, Richmond Agitation Sedation Score, Confusion Assessment Method for the ICU, ABC-MAX, ABC-123 subscores, and mobility level).

Perioperative Individualized Goal Directed Therapy for Cardiac Surgery: A Historical-Prospective, Comparative Effectiveness Study.

Introduction: Cardiac surgery patients are at increased risk for post-operative complications and prolonged length of stay. Perioperative goal directed therapy (GDT) has demonstrated utility for non-cardiac surgery, however, GDT is not common for cardiac surgery. We initiated a quality improvement (QI) project focusing on the implementation of a GDT protocol, which was applied from the immediate post-bypass period into the intensive care unit (ICU).

Remote Ischemic Pre-conditioning in Subarachnoid Hemorrhage: A Prospective Pilot Trial.

Background: Cerebral injury from aneurysmal subarachnoid hemorrhage (aSAH) is twofold. The initial hemorrhage causes much of the injury; secondary injury can occur from delayed cerebral ischemia (DCI). Remote ischemic preconditioning (RIPC) is a mechanism of organ protection in response to transient ischemia within a distant organ.

Comparison of Three Point-of-Care Ultrasound Views and MRI Measurements for Optic Nerve Sheath Diameter: A Prospective Validity Study.

Introduction: Point-of-care ultrasound of the optic nerve sheath diameter (ONSD) to diagnose increased intracranial pressure (ICP) is of great interest in various clinical scenarios. Yet, the lack of examination standardization has made clinical utility difficult. We compare three ultrasound ocular plane views (inferior, sagittal, and transverse), which are currently used in the literature to evaluate their consistency.

Improved diagnostic accuracy of pathology with the implementation of a perioperative point-of-care ultrasound service: quality improvement initiative.

Introduction: The utility of perioperative point-of-care ultrasound (P-POCUS) is rapidly growing. The successful implementation of a comprehensive P-POCUS curriculum, Focused PeriOperative Risk Evaluation Sonography Involving Gastro-abdominal, Hemodynamic, and Trans-thoracic Ultrasound (FORESIGHT), has been demonstrated. This project sought to further evaluate the utility of P-POCUS with the following aims: (1) to assess the ability to train the FORESIGHT curriculum via a free, open-access, online platform; (2) to launch a P-POCUS clinical service as a quality improvement (QI) initiative; (3) to evaluate the diagnostic accuracy of the P-POCUS examinations to formal diagnostic studies; and (4) to compare the P-POCUS diagnostic accuracy with the diagnostic accuracy of traditional assessment (TA).

Beta Blockade and Clinical Outcomes in Aneurysmal Subarachnoid Hemorrhage.

Background: Aneurysmal subarachnoid hemorrhages are frequently complicated by hypertension and neurogenic myocardial stunning. Beta blockers may be used for management of these complications. We sought to investigate sympathetic nervous system modulation by beta blockers and their effect on radiographic vasospasm, delayed cerebral infarction, discharge destination and death.

The Relationship Between Oxygen Reserve Index and Arterial Partial Pressure of Oxygen During Surgery.

Background: The use of intraoperative pulse oximetry (SpO2) enhances hypoxia detection and is associated with fewer perioperative hypoxic events. However, SpO2 may be reported as 98% when arterial partial pressure of oxygen (PaO2) is as low as 70 mm Hg. Therefore, SpO2 may not provide advance warning of falling arterial oxygenation until PaO2 approaches this level.

Impact of a 2-Day Critical Care Ultrasound Course during Fellowship Training: A Pilot Study.

Objectives. Despite the increasing utilization of point-of-care critical care ultrasonography (CCUS), standards establishing competency for its use are lacking. The purpose of this study was to evaluate the effectiveness of a 2-day CCUS course implementation on ultrasound-naïve critical care medicine (CCM) fellows.

Evaluation of multiple modes of oximetry monitoring as an index of splanchnic blood flow in a newborn lamb model of hypoxic, ischemic, and hemorrhagic stress.

Early and aggressive treatment of circulatory failure is associated with increased survival, highlighting the need for monitoring methods capable of early detection. Vasoconstriction and decreased oxygenation of the splanchnic circulation are a sentinel response of the cardiovasculature during circulatory distress. Thus, we measured esophageal oxygenation as an index of decreased tissue oxygen delivery caused by three types of ischemic insult, occlusive decreases in mesenteric blood flow, and hemodynamic adaptations to systemic hypoxia and simulated hemorrhagic stress.

Implementation of a post-cardiac arrest care bundle including therapeutic hypothermia and hemodynamic optimization in comatose patients with return of spontaneous circulation after out-of-hospital cardiac arrest: a feasibility study.

Patients who present to the emergency department (ED) with return of spontaneous circulation after cardiac arrest generally have poor outcomes. Guidelines for treatment can be complicated and difficult to implement. This study examined the feasibility of implementing a care bundle including therapeutic hypothermia (TH) and early hemodynamic optimization for comatose patients with return of spontaneous circulation after out-of-hospital cardiac arrest.

Hydrogen gas is ineffective in moderate and severe neonatal hypoxia-ischemia rat models.

Hydrogen gas (H(2)) has been shown to ameliorate brain injury in experimental adult rat focal ischemia and in a mild neonatal hypoxia-ischemia (HI, 90 min hypoxia) rat model. In this study we tested H(2) in moderate (120 min hypoxia) and severe (150 min hypoxia) neonatal HI rat models. We hypothesized that H(2) would improve outcomes after neonatal HI by scavenging free radicals.

Deep hypothermia and circulatory arrest in adults.

Brain protection during cardiopulmonary bypass has been the subject of intense research. Deep hypothermic circulatory arrest (DHCA) continues to be used for that goal during complex aortic arch and large intracranial aneurysm surgeries. The anesthetic management for adult patients undergoing these types of procedures requires specific knowledge and expertise.

Change in Cardiopulmonary Arrest Response in an Anesthesiology Residency: A practice-based learning initiative.

Because of increases in the acuity in our patient population, increasing complexity of the care provided and the structure of our residency, we decided to systematically alter our participation in the hospital-wide cardiac arrest system. The need to provide optimum service in an increasingly complex clinical care system was the motivation for change. With substantive input from trainees and practitioners, we created a multi-tier-system of response along with predefined criteria for the anesthesiology response.

Multiple sclerosis and anesthetic implications.

Purpose Of Review: Multiple sclerosis remains prevalent among young women in the United States of America. It is a disease of the central nervous system that possesses many anesthetic implications. Anesthesia providers need to understand this disorder and its multiple anesthetic ramifications.

Teaching and evaluating professionalism for anesthesiology residents.

The Accreditation Council for Graduate Medical Education Outcome Project requires teaching and evaluation of 6 core competencies, one of which is professionalism. Because of this initiative, anesthesiology residency programs are obliged to teach and evaluate professionalism for anesthesiology residents. We decided to create a system that would allow the teaching and evaluation of professionalism in the specific context of anesthesiology.

Changing of an anesthesiology clinical base year to create an integrated 48-month curriculum: experience of one program.

To allow for growth in our anesthesiology residency, we assumed control of the clinical base year (postgraduate year 1[PGY-1]) and adjusted the curriculum to accommodate the expanded size. With this opportunity to change the curriculum, we created a clinical base year to prepare PGY-1 for clinical anesthesia training in PGY-2 to PGY-4 using, for this purpose, the best resources of our clinical site. We describe the process and preliminary results of the change.

Transurethral resection syndrome after bladder perforation.

The use of irrigating solutions is essential for distension of mucosal surfaces and visualization of the surgical field during resectoscopic resection of bladder tumors (TURBT). TURBT resection may be complicated with bladder perforation associated with intraperitoneal extravasation of irrigant fluid, which may rarely evolve in specific hydroelectrolyte imbalance characterized with hyponatremia, intravascular volume deficit, and renal impairment. We report four cases of TURBT syndrome during bladder surgery complicated by bladder perforation and discuss issues relevant to pathophysiology, diagnosis, and treatment of this rare condition.
