当人们生病的时候,医生会用各种办法帮助病人缓解病痛。在有些情况下,医生会通过实施手术,深入人体内部去修复受损的不能正常工作的器官。随着技术的发展,外科医生能够成功地完成越来越多的难度惊人的手术。化学睡眠现代外科手术依赖麻醉(通过药物接触使身体失去知觉)。麻醉确保人在手术过程中感觉不到疼痛。麻醉药可以通过注入血液或从口中吸入身体。普通麻醉会使人进入深度睡眠状态,这时仪器会为人检查心跳、血压和呼吸。 When people get sick, the doctor can use various methods to help the patient relieve the pain. In some cases, the surgeon will go deep into the body to repair damaged organs that do not work properly. As technology advances, surgeons can successfully accomplish more and more difficult and surprising operations. Chemical Sleep Modern surgery relies on anesthesia (unconsciousness through drug contact). Anesthesia ensures that people do not feel pain during surgery. Narcotics can be injected into the blood or from the mouth into the body. Ordinary anesthesia will make people into deep sleep, then the instrument will check heart rate, blood pressure and breathing.
