(3) 如何治疗?

答案

参考答案:治疗原则:① 控制感染:参考细菌学检查结果选用适当的抗生素;细菌学结果明确以前,可根据常见致病菌选择1~2种广谱抗生素。提倡足量、联用并注意选用血脑屏障通透性较好的药物。② 通畅引流:在大剂量抗生素应用的同时,尽早施行乳突手术,清除病灶,通畅引流;一旦影像学检查提示脑脓肿形成,应及时引流或切除。③ 加强支持疗法,注意水与电解质平衡。④ 对症处理:包括全身中毒症状的处理、颅内高压及脑疝的预防和治疗等。

New research has revealed that which song drivers listen to can influence how safe they are on the roads.Among the top ten safest songs to drive to are Come Away With Me by Norah Jones,I Don't Want to Miss a Thing by Aerosmith and Tiny Dancer by Elton John.Each of the songs has an optimum tempo(最佳节奏) for safe driving,imitating the human heartbeat at around 60 to 80 beats per minute.The Scientist by Coldplay and Justin Timberlake's Cry Me a River also appeared in the top 10.

The study,conducted at London Metropolitan University,also revealed the type of songs that cause motorists to drive dangerously.Unsurprisingly,music that is noisy increases a driver's heart rate,which can be deadly.Fast beats cause excitement that can lead people to concentrate more on the music than on the road and to speed up to match the beat of the song.Styles of music were also measured during the experiment and revealed differences between male and female drivers.Hip­hop made a female driver drive far more aggressively,speeding up faster than male driver.The heavy metal music caused the fastest driving among males in the group while the dance music had the same effect among women.The male and female drivers who listened to the classical music drove the most irregularly.

The experiment involved eight people driving 500 miles each using the confused.com MotorMate app,which monitored driving behaviors through GPS technology.
