We believe that critical care is not simply a location or a unit in a hospital, but the practice of providing care to those who need urgent support to treat or prevent a life-threatening illness. Whether you’re a paramedic, nurse, EM, IM, CCM doc, etc…


will help you critically appraise the literature so that you can deliver the highest quality, evidence based and compassionate care to your patients.

REBELCrit not only review’s recent publications, but has many review article’s, on often complex topics, to help you, the busy provider, continue to provide the best care possible. Soon, REBELCrit will be launching a critical care podcast through our already popular REBELCast!

REBELCrit strives to give you the most up to date and timely information so that you can be the best provider you can be and deliver the best care to your critically ill patients!

Background: It has well been established that low tidal volume ventilation minimizes potentially iatrogenic harms of mechanical ventilation.  What is less clear is the use of higher positive end expiratory pressure (PEEP) in patients without acute respiratory distress syndrome (ARDS). Use of PEEP helps prevent alveolar collapse and maintains recruitment of atelectatic and diseased alveoli.  This improves the distribution of lung aeration over a more homogenously inflated lung surface which in turn may improve oxygenation. Although PEEP reduces cyclical opening and closing of alveoli during ventilation, a higher PEEP could also lead to new lung injury (ventilator-induced lung injury), impair hemodynamics (reducing venous return) and could delay weaning/extubation.

Background Information: Out-of-hospital cardiac arrest (OHCA) remains a diagnostic challenge to providers and a significant burden on healthcare systems globally. Despite the advancement of invasive medical therapies such as percutaneous coronary intervention (PCI) and extracorporeal membranous oxygenation (ECMO) at designated cardiac catherization centers, the majority of these patients sustain poor outcomes due to hypoxic brain injury. Clinical features of neurologic injury are typically delayed until 72 hours after admission. As a result, many neuro-prognostication tools have been developed to assist with clinical decision making as well as reduce expensive futile interventions.1 Some of these neuroprognostication tools include the Cardiac Arrest Hospital Prognosis (CAHP), OHCA and Targeted Temperature Management (TTM) risk tools. Unfortunately, these are complex and time consuming, thus limiting their use in the emergency department (ED). The authors of the following study sought out to develop and validate a point-based risk score to support clinical decision making and predict neurologic outcomes using the cerebral performance category (CPC) scale (Figure 1)

Introduction: Respiratory failure is an uncommon but important complication in pregnancy and the postpartum period, occurring 1 in 500 pregnancies.1 Respiratory failure can result from pregnancy-related conditions, conditions exacerbated by pregnancy, or pathologies common to the general population (Table 1). Understanding of respiratory failure and mechanical ventilation in pregnant patients is limited by the relative rarity of the condition as well as the exclusion or underrepresentation of pregnant patients in the majority of the trials that have informed our understanding of respiratory failure. As such, respiratory failure in this vulnerable population is a stressful emergency that requires understanding of the anatomical and physiological changes of gestation as well as meticulous preparation for a difficult airway.

Background:  Vasopressors are usually given through central venous catheters (CVC). This, however, is a time-consuming process and placement of a peripheral venous catheter (PIV) is much faster. Each hour of delay has been associated with a 2% increase in in-hospital mortality.2 Using PIV for the infusion of vasopressors can be an effective alternative for time-sensitive patient care in the emergency department (ED). Previous studies, however, have been inconclusive regarding complications of vasopressor infusion through PIV.

Background: In the US out-of-hospital cardiac arrest (OHCA) has an estimated survival rate of <10% overall, but slightly better survival rates with shockable rhythms of approximately 30% [2]. A small proportion of these patients will have refractory VF/VT OHCA not treatable by standard ACLS guidelines.  One possible modality for these patients is extracorporeal membrane oxygenation (ECMO, followed by immediate coronary angiography and percutaneous coronary intervention (PCI).  How would this ECMO-facilitated resuscitation strategy fair when applied in a US metropolitan community?
