What You Need to Know About the SALAD Technique

Every year, more than 60,000 Americans die from complications of dysphagia and other swallowing disorders. The most common of these complications is aspiration pneumonia. Traumatic injuries that cause continuous bleeding into the airway can also lead to aspiration. Even with treatment, aspiration has a high mortality rate because it introduces contaminants into the airway. Mortality estimates vary depending on the population studied, but are at least 20-30 percent higher in the elderly and those with preexisting respiratory disorders.

 

Suction Assisted Laryngoscopy and Airway Decontamination (SALAD) can lower morbidities and mortality associated with aspiration and related syndromes. This technique allows first responders to deliver continuous suction, clearing the airway and reducing the volume of contaminants a patient aspirates.

 

What Is the SALAD Technique?

Blood in the airway and airway edema are the two most significant predictors of intubation failure. Dr. James DuCanto developed his SALAD technique to quickly clear the airway, eliminating the most common source of intubation failure and reducing the mortality rate associated with aspiration.

 

The SALAD technique uses aggressive suction to quickly clear the airway, allowing a first responder or other provider to intubate the patient. The catheter can be left in place during intubation, providing an easy route for removing blood or other contaminants during and after intubation. The technique offers easy access to the trachea, even when patients are continuously vomiting or bleeding. The technique is simple:

  • Use a rigid suction catheter, such as our SSCOR DuCanto catheter, which was specifically designed for the technique.
  • As you continuously suction, insert a laryngoscope blade while shifting the catheter to the corner of the patient’s mouth and left of the blade. Then position the tip of the catheter at the esophagus, allowing you to continue suctioning while visualizing the vocal cords.
  • Intubate the patient, suctioning the endotracheal tube before commencing ventilation.

 

Benefits of SALAD

Guides to airway contamination often treat it as a discrete incident, such as when a patient inhales vomit or drowns. But airway contamination may be ongoing, especially for the most critical and vulnerable patients. SALAD is the only technique specifically designed to address this scenario. The benefits of this revolutionary technique include:

  • Ease of use and modeling. The SALAD technique is easy to learn and even easier to train using mannequins. A 2017 study found that a modification to the airway of a mannequin made it possible to easily simulate a SALAD technique scenario.
  • Fewer inhaled contaminants. Aspiration can cause a patient to choke or become hypoxic, but also presents several long-term risks. The 30-day mortality rate is higher in patients who have aspirated because of their exposure to bacteria and other pathogens.
  • Real-world practicality. Traditional suction techniques do not work well on patients with continuously obstructed airways. Likewise, intubation ranges from dangerous to impossible in patients at risk of aspiration.
  • Compatible with virtually any suction device. The SALAD technique does not require any specific device. It can also work with a range of catheters, though the DuCanto catheter is the easiest and most effective option.

 

The Importance of the Right Equipment

In developing the SALAD technique, Dr. DuCanto found that using a wooden tongue depressor to open a patient’s jaw could aid insertion of the laryngoscope. At a time when seconds count, this saves up to 30 seconds. Seeking a better option, he worked with SSCOR to develop the DuCanto catheter. Its large inner diameter, curved and anatomically correct shape, and rigid plastic all allow for greater control, offering rapid airway access.

 

In emergency scenarios, being able to tend to the patient wherever they are is key. A portable emergency suction device shaves seconds and sometimes even minutes off of your response time. SSCOR’s battery-powered devices offer continuous and reliable suction and are compatible with the DuCanto catheter.
