<p>Here are some precautions for <a href="https://www.hondemedical.com/laryngeal-mask" rel="noopener noreferrer" target="_blank">laryngeal mask</a>:</p><p>(1) It is basically the same as that of endotracheal intubation, pay attention to the effect of ventilation, especially PetCO2, which often has an upward trend in children.</p><p>(2) Listen closely to the breathing sounds in order to find the reflux inhalation in time.</p><p>(3) During positive pressure ventilation, the internal airway pressure should not exceed 20cmH2O, air leakage or gas into the stomach may easily occur.</p><p>(4) After the operation, when the anesthesia has not been completely shallow, it can attract secretions accumulated in the hood, but it should be noted that the suction tube cannot directly contact the throat, because it is easy to induce laryngospasm.</p><p>5) The laryngeal mask is less irritating to the trachea. Remove the laryngeal mask when the patient is awake or can open the mouth by himself under instructions.</p><p>(6) The laryngeal mask does not produce the closing effect of the esophageal sphincter, but instead lowers the tension of the lower esophageal sphincter. Therefore, you should always be alert to the risk of sudden aspiration of stomach contents. Laryngeal masks are contraindicated in patients who are full of stomach or whose stomach contents remain high.</p><p>(7) Patients with severe obesity or reduced lung compliance often require higher airway pressure (> 20cmH2O) to perform assisted breathing or controlled breathing under the laryngeal mask. Therefore, it is prone to air leakage and the risk of gas induced vomiting, so it should be taboo. Once regurgitation and aspiration occur, the laryngeal mask should be removed immediately, the respiratory tract should be cleaned, and other ventilation methods should be used.</p><p>(
Patients with potential respiratory tract obstruction, such as tracheal compression, tracheal softening, throat tumors, abscesses, hematoma, etc., are prohibited from using laryngeal masks.</p><p>(9) Laryngeal masks are not suitable for patients who need special surgical positions such as prone position.</p><p>(10) Putting the laryngeal mask under light anesthesia is prone to laryngospasm, and the laryngeal mask should be inserted after the laryngeal reflex as deep anesthesia.</p><p>(11) Before the laryngeal mask comes into contact with the hard palate, the laryngeal mask must be fully unfolded and then gradually fed into the pharyngeal cavity. If the laryngeal mask meets resistance behind the tongue, it cannot be forcibly inserted, and the catheter at the end of the mask cannot be discounted to prevent damage. The laryngeal mask should be properly fixed after the insertion.</p><p>(12) Pay attention to choose a proper size laryngeal mask. If the laryngeal mask is too small, it will be inserted too deeply, causing poor ventilation; if the laryngeal mask is too large, it is not easy to be in place and easy to leak.</p><p>(13) Before use, the laryngeal mask should be routinely checked for leaks around the mask.</p><p>(14) After the laryngeal mask is placed, the mandibular jaw operation cannot be performed, it is easy to cause laryngeal spasm or laryngeal mask displacement.</p><p>(15) Pay close attention to the presence of airway obstruction during the operation. Patients with many respiratory secretions are not easy to clear through the laryngeal mask.</p><p><br></p>
