The idea of endoscopic surgery has me concerned about how safe it is for me. For example, during inspiration, the entire larynx falls downward in the neck, a movement that pulls the epiglottis up and away from the glottis, further opening the airway. Early diagnosis and aggressive treatment of laryngospasm are imperative, since succinylcholine administration in the face of hypoxia and hypercarbia may result in profound bradycardia and asystole. folding of epiglottis over glottic opening, lifts the epiglottis and tongue off the glottic opening, rocks the larynx forward, counteracting some of the tension bunching the vocal cordstogether, pulls the aryepiglottic folds connecting the sides of the epiglottis to the back of the arytenoids, opening a small gap between the vocal cords, stimulates the patient because its painful, perhaps awakeningthe patient out of Stage II toward consciousness. My recommendation would be to discuss this with your primary care physician as you are at high risk of pulmonary aspiration.

However, it may be detrimental if there is sustained closure of the glottis resulting in blockage of respiration that hinders the free flow of air. May I ask one very crucial question- It is time sensitive. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Laryngospasm LITFL Medical Blog CCC Ventilation The swallowing mechanism helped open my airway and I took in sipping breaths of air until it began to recede. } Laryngospasm accounts for more than 50% of the cases of negative pressure/post obstructive pulmonary edema. ok so does the laryngospasm or larson manuever work on awake patients who happen to get laryngospasms for no reason? PubMed PMID. Typically, laryngospasm is promptly recognized and routinely managed with airway manipulation, such as with the jaw-thrust maneuver and administration of CPAP with a mask, and briefly increasing the depth of anesthesia.6 Laryngospasm can be reduced with propofol, a strong depressant of airway reflexes7; propofol also can reduce [2][8], In children, rapid detection and management are imperative to prevent deadly complications such as cardiac arrest, hypoxia and bradycardia. It does not surprise me that it took an hour for the combination of drugs they most likely used to wear off and it certainly does not imply that you were in danger during that time. Absolutely.

There has been a report of total airway obstruction after topical anesthesia of the larynx before fiberoptic intubation [76]. Secretions, irrigating solutions, blood, surgical debris, insufficient level of anesthesia, irritating gases, and pain may all initiate laryngospasm.

Half of the analyzed countries witnessed no substantial excess deaths versus pre-pandemic levels, [11] Treatment requires clearing secretions from the oropharynx, applying continuous positive airway pressure with 100% oxygen, followed by deepening the plane of anaesthesia with propofol, and/or paralyzing with succinylcholine.[10].
