Can’t Intubate, Can’t Ventilate (CICV) Situation Following Airway Hemorrhage

A “can’t intubate, can’t ventilate” (CICV) situation is a critical and life-threatening scenario that can occur in anesthesia and emergency medicine, especially when complicated by airway hemorrhage. In such situations, immediate and organized actions are essential to secure the patient’s airway and provide adequate ventilation and oxygenation.

Common Causes of CICV Following Airway Hemorrhage:

  1. Hemorrhagic Airway Obstruction: Severe bleeding within the upper airway can obstruct the passage of both ventilation and intubation devices.
  2. Coagulopathy: Patients with bleeding disorders or those on anticoagulant medications are at increased risk of uncontrolled hemorrhage.
  3. Airway Tumors: Tumors or masses in the airway or adjacent structures may bleed profusely and impede access to the airway.
  4. Trauma: Blunt or penetrating trauma to the airway, neck, or face can cause hemorrhage and compromise the airway.

Plan of Action for Anesthesiologists in CICV Following Airway Hemorrhage:

  1. Immediate Recognition: Rapidly recognize the signs of CICV, including inadequate ventilation, severe hemorrhage, and worsening oxygen saturation.
  2. Activate the Emergency Response: Alert the healthcare team and initiate a “Code CICV” or similar emergency response, which should involve additional experienced personnel, including a surgical airway specialist, if available.
  3. Positioning: Place the patient in the optimal sniffing position to align the airway and facilitate visualization during any attempted intubation.
  4. Initial Attempts at Intubation: a. Attempt Laryngoscopy: Make an initial attempt at laryngoscopy with a direct laryngoscope equipped with a Macintosh or Miller blade to visualize the glottis. b. External Laryngeal Manipulation (ELM): Apply external laryngeal manipulation to optimize the laryngeal view if possible. c. Alternate Blades: Consider switching to an alternate laryngoscope blade type (e.g., from Macintosh to Miller or vice versa) if the initial blade does not provide a clear view. d. Video Laryngoscopy: If available, use video laryngoscopy for improved visualization of the airway.
  5. Supraglottic Airway Devices: If intubation attempts are unsuccessful or if hemorrhage makes visualization impossible, consider inserting a supraglottic airway device (e.g., laryngeal mask airway, LMA) as a bridge to secure the airway. Ensure proper placement and ventilation through the device.
  6. Surgical Airway Consideration: If all attempts at intubation and supraglottic device placement fail, prepare for a surgical airway (cricothyroidotomy or tracheostomy). This should be considered an urgent procedure and performed by an experienced provider.
  7. Hemostasis: Simultaneously, attempt to control hemorrhage using direct pressure, hemostatic agents, or other interventions as appropriate to maintain a clear field of view.
  8. Communication: Maintain clear communication with the healthcare team, providing updates on the situation and the progress of interventions.
  9. Continuous Monitoring: Continuously monitor oxygen saturation, end-tidal CO2, and other relevant vital signs to assess the effectiveness of interventions and patient status.
  10. Blood and Fluid Resuscitation: Administer blood products and fluids to manage hemorrhagic shock and maintain hemodynamic stability.
  11. Prepare for Definitive Airway: Once the airway is secured, either temporarily or definitively, evaluate the underlying cause of hemorrhage and plan for appropriate management, which may include further intervention or surgical procedures.

It is crucial to have a well-rehearsed CICV protocol in place and to engage in regular team training to ensure a coordinated response to these high-risk situations. Quick decision-making, effective teamwork, and a systematic approach are paramount in managing CICV following airway hemorrhage to optimize patient outcomes and minimize complications.
