The preoperative visit of all patients by an anesthetist is an essential requirement for the safe and successful conduct of anesthesia.

Patients with a proven history of myocardial infarction are at a greater risk of perioperative reinfarction, the incidence of which is related to the time interval between infarct and surgery. Elective surgery should be postponed until at least 6 months after the event. Untreated or poorly controlled hypertension (diastolic consistently >110 mmHg ) may lead to exaggerated cardiovascular responses during anesthesia. Both hypertension and hypotension can be precipitated which increase the risk of myocardial ischaemia. Heart failure will be worsened by the depressant effects of anesthetic drugs on the heart, thereby impairing the perfusion valves may be on anticoagulants. These may need to be stopped or changed prior to surgery. Antibiotic prophylaxis will be required during certain types of surgery.
发生过心肌梗塞的病人有很大危险在术中发生在梗塞。择期手术应在心肌梗塞6个月后施行。在麻醉过程中，无治疗或者控制差的高血压（舒张压>110mmHg）或者低血压可能会导致循环大的波动。高血压和低血压均会增加心衰的危险性。心衰将会使得麻醉药在心脏的作用，减少心肌供血。以上的情况必须在术前纠正。预防性应用抗生素是必须的。

Ideally, the anesthetist should take a full history and examine each patient, but for the reasons already identified this is seldom possible. This section concentrates on features of particular relevance to the anesthetist.
理想的状况是麻醉医生应该充分了解患者病史并检查每一位患者，但是由于一些已知的原因却很难做到这一点。本部分将集中探讨与麻醉医生相关的方面。

For elective surgery, patients are rarely admitted more than 24 hours in advance and may not be seen by the anesthetist until the evening prior to surgery.

对于选择性手术，病人很少在24小时前入院，因而有可能在手术前晚麻醉医生才有机会看到病人。

英语中一些关于否定方面的用法只能接合前后文翻译，例如，not..because...，不同的场合表示的意思完全和中文相反。
本句的意思应该为：择期手术，少数病人事先住院不超过24h,可能到手术前一天晚上才被麻醉医师看到。

请问楼主以上帖是来自一篇文章么？是的话能不能给一个全文和出处啊？

1.     Sleep is an active process generated in the brain.
   2.     Structures in the brainstem, diencephalon, and basal forebrain control the sleep-wake cycle and are directly modulated by general anesthetics.
   3.     Sleep and anesthesia are similar states with distinct traits, with each satisfying neurobiologic features of the other.
   4.     Distinct memory functions are subserved by distinct neural structures.
   5.     Limbic system structures such as the hippocampus and amygdala are critical for memory and play a role in anesthetic-induced amnesia.
   6.     Although brainstem, diencephalon, and basal forebrain structures generate wakefulness, the contents of consciousness are thought to be generated by the cortex.
   7.     Multiple neural correlates of consciousness are thought to be the targets of general anesthetics.
   8.     Consciousness and subsequent explicit recall of intraoperative events—known as “awareness during general anesthesia”—occur in 1 to 2 cases per 1000.
   9.     Monitoring anesthetic depth has evolved to electroencephalographic methods, although limitations still exist.

Cardiovascular system
Specific inquiries must be made about:
        angina (its incidence, precipitating factors, duration, use of anti-anginal medications, e.g. glyceryl trinitrate (GTN) tablets or spray);
        previous myocardial infarction and subsequent symptoms;
        symptoms indicative of heart failure.
