Larson’s maneuver, a jaw thrust with bilateral pressure on the body of the mandible anterior to the mastoid process. If these fail, quickly deepend the anesthetic (using intravenous agents), followed by SCh (0.1-0.5 mg/kg). Laryngospasm Treatment
What is laryngospasm and Larson maneuver?
Larson's manoeuvre is bilateral firm digital pressure on the styloid process behind the posterior ramus of the mandible. It is essentially a vigorous jaw thrust with pressure between the posterior ramus of the mandible and anterior to the mastoid process. Click to see full answer. Then, how is Laryngospasm treated?
What is Larson maneuver in dentistry?
What is Larson's maneuver? Larson's manoeuvre is bilateral firm digital pressure on the styloid process behind the posterior ramus of the mandible. It is essentially a vigorous jaw thrust with pressure between the posterior ramus of the mandible and anterior to the mastoid process.
How did the anesthesiologist perform Larson's maneuver?
The anesthesiologist used his both third fingers to press both points between the mastoid and the ascending ramus of the mandible, the “laryngospasm notch,” (fig. 1) doing what is known as “Larson’s maneuver.” The pressure was applied with both fingers, inward and upward the point.
How does Larson's maneuver work?

Press the middleMoreProcess of the temporal bone and posterior to the ascending ramus of the mandible. Press the middle finger firmly on the notch in a cephalad. Direction some degree of jaw thrust may also be applied.
How do you release a laryngospasm?
Push both sides firmly inward towards the skull base. Simultaneously, push anteriorly similar to a jaw-thrust maneuver. This should break the laryngospasm within 1-2 breaths.
What's the name of the maneuver that can relieve laryngospasm?
Attempt to break the laryngospasm by applying painful inward and anterior pressure at 'Larson's point' bilaterally while performing a jaw thrust. Larson's point is also called the 'laryngospasm notch'. Consider deepening sedation/ anesthesia (e.g. low dose propofol) to reduce laryngospasm.
What happens during laryngospasm?
Laryngospasm (luh-RING-o-spaz-um) is a condition in which your vocal cords suddenly spasm (involuntarily contract or seize). As a result, your airway becomes temporarily blocked, making it difficult to breathe or speak. Laryngospasms are rare and typically last for fewer than 60 seconds.
Can you pass out from laryngospasm?
A person may suddenly awaken feeling as though they are suffocating. This condition is called sleep-related laryngospasm. It also is often related to GERD. Some people will actually lose consciousness during these episodes.
What does a laryngospasm sound like?
If you're able to breathe during a laryngospasm, you may hear a hoarse whistling sound, called stridor, as air moves through the smaller opening.
What is the best treatment for laryngospasm?
Treatment of laryngospasm should proceed traditionally by clearing supraglottic airway obstruction and soiling, CPAP with 100% O2, deepening of anaesthesia i.v., and paralysis using succinylcholine by the i.v., i.m., or i.o. route as appropriate.
What is Burp maneuver?
Applying backward, upward, rightward, and posterior pressure on the larynx (i.e., displacement of the larynx in the backward and upward directions with rightward pressure on the thyroid cartilage) is called the “BURP” maneuver and has been well described by Knill.
What causes laryngeal spasm?
The cause of vocal cord spasms is often unknown, and it is usually in response to a trigger such as anxiety or acid reflux. Acid reflux may cause a few drops of stomach acid backwash to touch the vocal cords, setting off the spasm. Laryngospasm can sometimes occur after an endotracheal tube is removed from the throat.
Is laryngospasm an emergency?
Laryngospasm is one of the more frightening events in anesthesia: the protective, reflex, spasmodic closure of the vocal cords that occurs when the vocal cords are stimulated.
What kind of doctor treats laryngospasm?
In contrast to respiratory physicians, otolaryngologists and anesthesiologists are experts in managing paroxysmal laryngospasm. Articles related to this condition are also published in otolaryngology, anesthesiology, and other specialized journals.
Laryngospasm quickly blunted by Larson Maneuver in a pediatric patient. A case report
Giuseppe and I, mask induction. Photo sent to 2013 Euroanaesthesia photo contest.
Case report
A six-year-old boy presented for cataract surgery in the right eye. The patient entered the operating room with his mother; he was calm and did not receive pre-anesthetic medication. After monitoring (pulse oximeter and cardioscope), a facial mask was adapted, and a mix of oxygen and nitrous oxide started to flow, in a Mapleson D circuit.
Trick of the Trade
This maneuver, mentioned in the anesthesia literature, is more based on a single physician’s longitudinal experiences (Dr. Philip Larsen, Professor of Clinical Anesthesiology at UCLA). Anecdotally, many pediatricians and anesthetists use it. I haven’t found any published studies on this maneuver though.
Technique
Firmly push the soft tissue just behind the earlobes of the patient’s ears. Be sure not to go too inferiorly along the ramus of the mandible. You want to push at a point as superior as you can go in this notch. Push both sides firmly inward towards the skull base. Simultaneously, push anteriorly similar to a jaw-thrust maneuver.
