As a foreign body in the throat, the catheter that goes deep into the throat will definitely stimulate some parts of the throat, thus forming a conditioned reflex, and the patient will feel sick and want to vomit. Therefore, patients are usually required to have an empty stomach examination, which can alleviate the pain. Of course, under such a strong stimulus, doctors usually give local anesthesia to the patient's throat, and the muscles related to the throat will be relaxed after anesthesia. At the same time, the stimulation of laryngoscope entering the patient is greatly reduced. Don't make any noise after laryngoscopy, and try not to eat spicy food and frozen drinks. Because the larynx will be more or less stimulated during laryngoscopy, it will appear more fragile than normal, so it is necessary to protect the larynx after laryngoscopy.
What is the difference between acute pharyngitis and chronic pharyngitis?
1. Although both of them are pharyngolaryngitis, the causes are different. Acute pharyngitis is an acute inflammation caused by bacterial infection of pharyngeal mucosa and lymphoid tissue, which is generally closely related to acute rhinitis and tonsillitis. Chronic pharyngitis of the ear is a chronic inflammation of the pharyngeal mucosa, which is mostly caused by long-term stimulation of the pharynx.
2, the symptoms and reactions of the two are also different. Acute pharyngitis is more acute. At first, my throat was dry and hot, and there was a strong pain in my throat. The pain is more severe when eating, which leads to difficulty in eating and loss of appetite. In the worst case, swallowing saliva can also cause pain, and some patients will also have symptoms of headache and fever. Chronic pharyngolaryngitis has no obvious sore throat, and is generally manifested as pharyngeal discomfort, mainly manifested as foreign body sensation, dryness and itching, and the condition is aggravated in the case of talking too much and fatigue. There is nothing wrong with eating, but eating irritating food often leads to coughing.
Warm reminder, laryngoscopy needs to go to a regular hospital, the doctor will be relatively professional, and more detailed suggestions will be given before laryngoscopy. In order to avoid the problem of laryngeal spasm caused by insufficient anesthesia and careless operation during operation.
