2011 National Ear Care Day Promotional Materials

Source: Sichuan Online-Tianfu Morning News (Chengdu) According to relevant statistics, the number of people with hearing and speech impairment in my country is as high as 20.57 million, of which about 2 million are children, about 800,000 are children under 7 years old, and newborns have hearing impairment. The total incidence rate of impairment is 9.52‰. In addition, the number of hearing-impaired people is increasing at a rate of 20,000 to 40,000 per year. Some data show that elderly people over 30 have hearing impairment and need rehabilitation services and help.

Listen, listen, headphones sound the best! The heart-warming headphone advertisement has convinced many students to believe it. MP3, MP4, and mobile phones can be "played" by plugging in earphones. They look cool and handsome, but in fact, there is a danger of being deafened for 10 years early. Xue Kang, an ear, nose and throat expert, said that deafness among teenagers has increased significantly, and parents should pay close attention to it.

Infatuation with MP3 caused explosive deafness

According to Xue Kang, an ear, nose and throat expert, a student patient often listens to MP3 and puts on headphones to listen to music every night before going to bed. , often the MP3 player is still playing music while the person has already fallen asleep. During the winter vacation, the patient found that his ears began to ring, which he could not hear clearly, and he had to ask others to repeat it many times. Later, it developed to the point where the entire nervous system developed abnormal symptoms, with frequent dizziness and headaches, which were unbearable. The ears may even hurt when touched, which seriously affects study and life. After a doctor's tuning fork examination and pure tone test, it was found that his hearing had dropped by 40 decibels compared with ordinary people.

Xue Kang explained that in medical terms, this symptom of the above-mentioned patient is called "violent deafness".

Temporary deafness can evolve into permanent deafness

It is understood that students use MP3 and MP4 very frequently. Many students read, eat, and sleep with headphones on, which seems to have become a way of life for some students. What do parents think about their children's frequent use of MP3 and MP4? Many parents said that they do not use headphones themselves and have no in-depth understanding of them. They have never thought that long-term use of headphones can cause noise-induced deafness. They mistakenly believe that this is a way for children to entertain themselves, and they underestimate its harmfulness and do not take it seriously.

According to Xue Kang, an ear, nose and throat specialist, wearing headphones for a long time will cause a serious lack of blood supply to the ears and cause edema of ear cells. If not treated in time, it is easy to suffer from "occupational deafness". If you are still in a noisy environment, it will gradually evolve from temporary deafness to permanent deafness.

Improper use of headphones can lead to deafness for 10 years!

Headphones, players, etc. are the killers of noise-induced deafness. Long-term irrational use can damage hearing and cause hearing loss before reaching old age. It is not alarmist to say that teenagers will be deafened for 10 years early due to improper use of various types of players. Expert Xue Kang said that when people use earplugs to listen to sound, the sound energy goes directly to the cochlea without being digested by the outer ear and middle ear. Over time, it will damage the delicate hair cells of the inner ear. According to statistics, about 30% of outpatients with sensorineural deafness have damaged inner ear hair cells and nerves. It is worth noting that the hair cells in the inner ear cannot regenerate, so there is basically no effective treatment for sensorineural hearing loss.

Ear-loving tipsgt; , when the sound is adjusted to the highest setting, it will exceed 130 decibels, and the volume is equivalent to the sound of a jet taking off. The volume that human ears feel comfortable should not exceed 75 decibels. It is more appropriate to select a volume level of no more than 60 for music playing appliances.

Tip 2: Use over-ear headphones

Wearing earphones for a long time will directly stimulate the ear nerves and cause insufficient blood supply to the ears. By collecting sound waves from the outside, the user does not need to increase the MP3 volume to compete with the noise. It can better protect hearing and relieve ear pressure and insufficient blood supply. However, it should not be listened to for a long time.

Health concerns>gt; Antibiotics, but the former has a wider antibacterial range, but it is not needed at all for tonsillitis and minor colds.

"Relevant pharmaceutical experts said that in recent years, minor illnesses such as colds have often been treated "seriously". Nowadays, let alone penicillin, even first-generation cephalosporin drugs such as cefazolin and cephalexin are rare, but third- and fourth-generation cephalosporin drugs are rare. It is widely used and often used to treat colds. The fundamental reason for the abuse of antibiotics is the promotion of profit. The first, second, third and fourth generation cephalosporins are also used to treat colds. Therefore, the higher the level, the higher the price. It is not surprising to spend 1,800 yuan.

It is estimated that the irregular use of antibiotics leads to an unreasonable increase in medical expenses and the health of the people is sacrificed behind the huge benefits. Respiratory experts said that data show that antibiotic abuse is also one of the main culprits in cases of death from adverse drug reactions in my country. About 80,000 patients die from adverse drug reactions every year. Moreover, it takes about 10 years to develop an antibiotic. However, drug-resistant bacteria develop within two years. In clinical practice, we often encounter sad events in which antibiotics are no longer available due to misuse. “For the sake of health, the principle that should be followed in the use of antibiotics is to not use them when they are available. This must be done. Also start from the lowest. "Pharmaceutical experts said that after the implementation of the national essential drug system in all primary hospitals, classic antibiotic drugs such as penicillin and gentamicin have returned, and only these drugs can be used, which is very beneficial to curb the abuse of antibiotics.
