22 SHOCK IN THE AVIAN PATIENT

23 INITIAL STABILIZATION OF THE AVIAN PATIENT:DEFINITION OF SHOCK SHOCK a syndrome precipitated by a systemic derangement of perfusion leading to widespread cellular hypoxia and vital organ dysfunction the state in which profound and widespread reduction of effective tissue perfusion leads first to reversible, and if prolonged, irreversible cellular injury inadequate blood volume - most commonly hypovolemic shock effective tissue perfusion may be reduced by either global reduction of systemic perfusion (cardiac output) increased ineffective tissue perfusion due to maldistribution of blood flow, or a defect of substrate utilization at the subcellular level

24 INITIAL STABILIZATION OF THE AVIAN PATIENT:DEFINITION OF SHOCK SHOCK a syndrome precipitated by a systemic derangement of perfusion leading to widespread cellular hypoxia and vital organ dysfunction the state in which profound and widespread reduction of effective tissue perfusion leads first to reversible, and if prolonged, irreversible cellular injury WHAT THE HECK DOES THAT MEAN? inadequate blood volume - most commonly hypovolemic shock effective tissue perfusion may be reduced by either global reduction of systemic perfusion (cardiac output) increased ineffective tissue perfusion due to maldistribution of blood flow, or a defect of substrate utilization at the subcellular level

25 INITIAL STABILIZATION OF THE AVIAN PATIENT:ASSESSMENT OF SHOCK, THE ABC AIRWAY Ensure that the patient has a clear airway Endotracheal intubation or air sac tube placement may be warranted ET or air sac tube placement

26 INITIAL STABILIZATION OF THE AVIAN PATIENT:ASSESSMENT OF SHOCK, THE ABC BREATHING Dyspneic or collapsed birds may be placed in oxygen enclosure while treatment is considered and organized Respiratory rate and effort closely monitored Upper vs. Lower Respiratory Oxygen supplementation Manual ventilation 1 breath per 4-5 seconds if intubated/air sac tube placed

27 INITIAL STABILIZATION OF THE AVIAN PATIENT:ASSESSMENT OF SHOCK, THE ABC CIRCULATION Maintenance of cardiac output and circulatory volume is essential to ensure adequate tissue oxygenation Control hemorrhage if present Assess ulnar/basilic/jugular vein filling time (>0.5s is indicative of poor peripheral perfusion) Mainstay of this is fluid therapy Birds deal with hemorrhage better than mammals respiratory tract Hypovolemic shock is commonly seen and caused by inadequate blood volume. Absolute hypovolemia occurs due to hemorrhage from trauma, coagulopathies or gastrointestinal tract bleed. Relative hypovolemia occurs with severe dehydration from the GIT or with extreme loss of fluids into a third body space (e.g., abdominal ascites.)birds tolerate hemorrhage better than mammals but if there is severe ongoing hemorrhage monitor the PCV and give intravenous or intraosseous fluids. Give vitamin K, calcium and antibiotics as necessary. The use of steroids in hemorrhage and hypovolemic shock is not currently recommended.
