12月5日星期一,預約了 GH ENT 部門給你做Hearing test.這一次應該會採用BERA,sedation讓你入睡再做測試.雖然爸爸媽媽很不願意讓你用藥.問過了GH的小兒科醫生,醫生說沒關係.也請教 過LGL Mr. Alex跟DAN! DR.他們不怎麼鼓勵用藥.媽媽選擇了讓你明天不夠睡,就半夜叫你醒,然後陪你玩到天亮.希望你能乖乖在預約的時間睡著.這樣可以不用藥就能完成測試.這是Tongtong給媽媽提出的建議.真的是太好了,太感恩了.
媽媽今晚就搜索些有關資料讀看.

Common sedative used
To achieve the highest-quality recordings for any recording potential, good patient relaxation is generally necessary. However, many recordings can be filled and contaminated with myogenic and movement artifacts. Patient restlessness and movement will contribute to threshold overestimation and inaccurate test results. In most cases, an adult is usually more than capable to provide a good extratympanic recording. In transtympanic recordings, a sedative can be used when time consuming events need to take place. Most patients (especially infants) are given light anesthesia when test transtympanically.

Chloral Hydrate is a commonly prescribed sedative, and most common for inducing sleep in young children and infants for AEP recordings. It uses alcohol to depress the central nervous system, specifically the cerebral cortex. Side effects of chloral hydrate include vomiting, nausea, gastric irritation, delirium, disorientation, allergic reactions and occasionally excitement – a high level of activity rather than becoming tired and falling asleep. Chloral Hydrate is readily available in three forms – syrup, capsule and suppository. Syrup is most successful for those 4 months and older, proper dosage is poured in an oral syringe or cup. The syringe is used to squirt in the back of the mouth and then the child is encouraged to swallow. To induce sleep, dosages range anywhere from 500 mg to 2g, the recommended pediatric dose is equal to 50 mg per kg of body weight. A second dose no greater than the first dose, and an overall dose not exceeding 100 mg/kg of body weight can be used if the child does not fall asleep after the first dose. Sedation personnel should include a physician and a registered or practical nurse. Documentation and monitoring of physiologic parameters is required throughout the entire process. Sedatives should only be administered in the presence of those who are knowledgeable and skilled in airway management and cardiopulmonary resuscitation (CPR).
