Study Notes
Partially Obstructed Airway
- Signs include forceful coughing, ability to breathe, wheezing, hand position on the throat, signs of panic, and cyanosis.
- Management involves placing the patient on their side, leaning into a head-down position, and encouraging coughing until the object is expelled.
- Back blows are no longer recommended for partially obstructed airways.
- After expulsion of the object, the patient should remain upright.
- If the patient stops coughing and cannot speak, treatment must proceed as for complete airway obstruction.
Completely Obstructed Airway
- Signs include distress, gripping the throat, inability to speak or breathe, panic, and potential loss of consciousness.
- Very poor air exchange may present as crowing or stridor; treat as a complete obstruction.
Emergency Management for Conscious Patients
- With good airway exchange: do not interfere, allow the victim to attempt to remove the object, and monitor their condition.
- With poor airway exchange: perform the Heimlich maneuver continuously until the object is expelled or the person loses consciousness.
- Consent should be obtained by asking the patient if they are choking.
Emergency Management for Unconscious Patients
- Position the patient supine on a hard surface and call EMS.
- Retrieve an AED and initiate Basic Life Support (BLS).
- Check for pulse and breathing, administer 30 chest compressions, check for the object, and provide breathing at a ratio of 30:2.
Aspiration of Objects
- Involves entry of objects into the lung, which can lead to serious conditions requiring removal to prevent infection or death.
Signs and Symptoms of Airway Aspiration
- Immediate symptoms may include dyspnea, hoarseness, wheezing, coughing, and cyanosis.
- Long-term symptoms can develop within a week, such as fever, chest pain, tachypnea, weight loss, and possible death if untreated.
Treatment of Aspirated Objects
- Contact EMS if breathing is difficult and conduct a chest radiograph.
- If an object is located, bronchoscopy is often performed for removal.
- Untreated aspiration may result in inflammation, infection, and necrosis of lung tissue.
Ingestion of Foreign Objects
- Approximately 90% of ingested objects pass through the GI tract without issue within 2-12 days; 10% may cause impaction or perforation.
- Most incidents occur when individuals are in supine or semi-supine positions, common in dental practices.
Prevention Techniques for Dental Practices
- Effective measures include using rubber dams, floss for quick retrieval, and other isolation methods.
- Maintain adequate visibility and never leave patients unattended with items in their mouths.
General Considerations
- The most common aspirated objects are food (like grapes, hot dogs) and dental appliances.
- Young children are particularly at risk, with hundreds of deaths reported annually from aspiration-related incidents.
