Misconception 1: Abusing antibiotics and actually trying to generate revenue. Your baby just has a minor sinus infection and your doctor prescribes a month’s worth of antibiotics, trying to generate revenue? Antibiotics play a pivotal role in the treatment of sinusitis. The antibiotics used for acute and chronic sinusitis are different due to different causes. Dongguan Children’s Hospital pediatric otolaryngology Jan Jiang, deputy chief physician, said that according to the 2012 Chinese Medical Association Ear, Nose and Throat Branch of the nasal ~ sinusitis treatment guidelines, for acute sinusitis (symptoms last no more than 12 weeks), the second or third generation cephalosporin antibiotics, amoxicillin clavulanic acid potassium are generally preferred; while for chronic sinusitis (symptoms last more than 12 weeks), clarithromycin is recommended. Sinusitis medications do take quite a long time to administer. For example, acute sinusitis requires about 2 weeks or 3-5 days of continued medication after the purulent nasal discharge subsides; chronic sinusitis requires more than 12 weeks of medication. Many parents are unaware of this and suspect that the doctor’s motives are impure, so they refuse to use the medication or use it intermittently, resulting in inflammation that is difficult to cure. Misconception 2: Hormones are fiercer than tigers. It is said that hormones have adverse effects when used in excess, but the doctor even let his daughter spray her nose for at least two months! The application of topical glucocorticosteroids (such as endosulfan, co-corticosteroids, and ryanodine, etc.) is crucial to the treatment of sinusitis. However, some parents have a deep-rooted negative impression of hormones and refuse to accept long-term medication. In fact, the amount of steroid hormones absorbed locally is very small when used in the nasal cavity; moreover, the high receptor affinity and low bioavailability of these hormones have even more minimal effects on the human body. Therefore, even in chronic sinusitis, which requires medication for more than 12 weeks, there is no need to be overly concerned. However, we do not advocate oral or intravenous or nasal hormone injections. Misconception 3: Use vasoconstrictors for nasal congestion. When my son first started using nasal drops, the effect was not bad, but then the more he used it, the worse it got, and now the nasal congestion is more powerful than before. The use of low concentration vasoconstrictors when nasal congestion, such as nasal drip (the main component is naphthazoline hydrochloride), ephedrine, etc., can indeed contract the nasal mucosa blood vessels, reduce mucus secretion, thus playing a role in reducing nasal congestion, nasal cavity. But the medication generally should not exceed 7 days, otherwise, excessive vasoconstriction may lead to secondary expansion of the mucosal vessels, ‘rebound congestion’, the turbinates are more swollen, worse nasal ventilation, but also may cause the destruction of nasal cilia off, resulting in drug rhinitis, affecting the defense function of the nasal cavity. Misconception 4: Replacement therapy is very powerful. Not only patients, but also doctors have some treatment misconceptions. At present, there are also hospitals that carry out negative pressure replacement therapy, the principle of which is to use negative pressure to suck out the purulent secretions from the sinuses and then instill drugs such as antibiotics into them. However, the disadvantage is that while the negative pressure sucks out the sinus secretions, it may also bring the purulent secretions in the nasal cavity into the sinuses, thus causing secondary infection. Therefore, the therapy is not really advisable. The use of nasal irrigation can clean the purulent nasal secretions from the child’s nose and prevent them from irritating the nasal mucosa.
