Essential Techniques for Opening an Obstructed Airway in an Unconscious Patient

Ensuring an unobstructed airway in an unconscious patient is crucial for effective breathing and overall survival. When a patient is unconscious, their muscles, including those controlling the airway, relax, which can lead to airway obstruction. Here are common techniques for managing and opening an obstructed airway in such scenarios.



1. Head-Tilt/Chin-Lift Maneuver

The head-tilt/chin-lift maneuver is a fundamental and widely used technique to open an airway.

  • Steps to perform the head-tilt/chin-lift maneuver:
    • Place one hand on the patient's forehead and apply firm, backward pressure with your palm to tilt the head back.
    • Place the fingertips of your other hand under the bony part of the chin and lift the chin upwards. This lifts the tongue away from the back of the throat, thereby opening the airway.

This maneuver is particularly effective in patients without suspected spinal injuries. However, caution is needed if spinal injury is suspected, as it could exacerbate the injury.

2. Jaw-Thrust Maneuver

The jaw-thrust maneuver is an alternative to the head-tilt/chin-lift and is especially useful when a spinal injury is suspected.

  • Steps to perform the jaw-thrust maneuver:
    • Kneel behind the patient's head.
    • Place your hands on each side of the patient's head, with your fingers under the angles of the lower jaw.
    • Lift the jaw forward by applying upward pressure with your fingers, which will move the jaw and tongue forward, opening the airway.

This technique minimizes neck movement, reducing the risk of further spinal injury.

3. Recovery Position

If the patient is breathing and has no suspected spinal injury, placing them in the recovery position can help keep the airway clear.

  • Steps to place a patient in the recovery position:
    • Kneel beside the patient and straighten their limbs.
    • Place the arm nearest to you at a right angle to the body, with the elbow bent.
    • Bring the far arm across the chest and hold the back of the hand against the patient’s cheek nearest to you.
    • With your other hand, grasp the far leg just above the knee and pull it up, keeping the foot flat on the ground.
    • Pull the knee towards you and roll the patient onto their side.
    • Tilt the head back to ensure the airway remains open.

This position allows any fluids, such as vomit, to drain from the mouth, preventing aspiration and further airway obstruction.

4. Oropharyngeal and Nasopharyngeal Airways

For more advanced airway management, healthcare providers may use oropharyngeal (OPA) or nasopharyngeal (NPA) airways.

  • Oropharyngeal Airway (OPA): This device is inserted into the mouth to keep the tongue from covering the epiglottis, which could block the airway. It's typically used in deeply unconscious patients who have no gag reflex.

    • To insert an OPA:
      • Open the patient's mouth and clear any obstructions.
      • Insert the airway with the curved end facing the roof of the mouth.
      • Once it reaches the back of the throat, rotate it 180 degrees so that the curved part follows the natural curve of the tongue.

  • Nasopharyngeal Airway (NPA): This is a tube inserted through the nose into the throat, providing a passage for air. It's useful when the patient has a gag reflex or if the mouth is injured.

    • To insert an NPA:
      • Lubricate the tube.
      • Insert it gently into one nostril, guiding it along the floor of the nasal cavity until it reaches the pharynx.

5. Suctioning

Suctioning is crucial for removing secretions, blood, or vomit from the airway.

  • Steps for effective suctioning:
    • Use a suction catheter or device.
    • Insert the catheter into the patient's mouth or nasopharynx.
    • Apply suction while withdrawing the catheter, ensuring not to suction for more than 15 seconds at a time to avoid hypoxia.

6. Advanced Airway Techniques

In critical situations, advanced techniques such as endotracheal intubation or surgical airway interventions (e.g., cricothyrotomy) may be necessary. These procedures should only be performed by trained medical professionals.

  • Endotracheal Intubation: Involves inserting a tube through the mouth into the trachea to secure the airway.
  • Cricothyrotomy: An emergency procedure to provide an airway by making an incision in the neck and inserting a tube into the trachea.

Conclusion

Opening an obstructed airway in an unconscious patient requires prompt and appropriate action. The head-tilt/chin-lift maneuver, jaw-thrust maneuver, recovery position, and use of oropharyngeal and nasopharyngeal airways are fundamental techniques. Suctioning is essential for clearing fluids, and advanced interventions are reserved for trained professionals. By mastering these techniques, first responders and healthcare providers can significantly improve patient outcomes in emergencies.

When Google collided with the Indian Institute of Emergency Medicine!

Many individuals still believe that emergency medical training is something that only doctors should perform. However, as you are aware, the term "emergency" refers to a situation that cannot wait for someone or anything to happen! This emergency can occur anywhere and at any moment, and it often does so at the most inconvenient times. This is where persons who have taken courses in emergency and disaster preparedness come in handy. In life-threatening situations, such people can save lives. On a typical day, a person spends the most of his time at work rather than at home. As a result, there are increased chances of an emergency situation occurring at work! Working professionals might benefit from corporate first aid training by assisting and supporting one another in such instances. This is why corporations should adopt the fundamentals of CPR training (AHA) and first aid training (AHA). The AHA recognised First Aid CPR AED Heartsaver course from IIEMS was provided to Googl

Best Institute of Emergency Medical Services in India

  Why Emergency Medical Services in India? Did you know there are more than 100,000 road/traffic-related deaths a year?  There are still around 40-60% of ambulances that do not have any medical equipment and around 95% of ambulances do not have trained personnel. All of these lead to one result- the death of the victim! Emergency Medical Services consist of a set up an initial response team along with facilities to efficiently respond to accidents and save deaths. Such a team and facilities  How do other countries reduce deaths caused by accidents? Well, we are not going into the comparison of road infrastructures of many developed countries with ours. In terms of emergency services, the least time the emergency response team takes to arrive at the place of the incident is 7 minutes. They still keep on improving the speed at which the response team arrives and the skills of the team. The aim here is to save the victim before getting them to ICU. India has a lot to learn from the countr

Commonly held reservations regarding the ACLS course!

 The need for BLS and ACLS courses has been recognised by the healthcare industry worldwide. Almost every hospital emergency department now demands ACLS certification for medical personnel. When compared to other healthcare professionals, those who hold genuine ACLS certification get 97.2 percent industry recognition. As a result, it's understandable that the demand for ACLS courses would be stronger. As a result of the increased demand, there is a surge in false information and phoney ACLS course providers. Huge discounts and certification in a short period of time are two frequent marketing strategies used to entice candidates. This leads to negative experiences for students who enrol in these bogus schools, which can have a negative impact on their careers. Overall, negative experiences with institutions can cause applicants to have doubts about their ability to achieve their goals. 1. Is it possible to take an ACLS course online? Ans. Yes, both online and offline versions of th
