While our ability to detect and manage fever has evolved since its conceptualization in the 5thcentury BC, controversy remains over the best evidence-based practices regarding if and when to treat this physiologic derangement in the critically ill.
In the worst case, if you have cancer, ‘letting the sickness run its course’ is dying. Cancer treatment is very bad for you (why only people who are proven to have cancer will be offered it) but cancer is even worse!
(II) fever is a protective adaptive response that should be allowed to run its course under most circumstances. The latter approach, sometime referred to as the “let it ride” philosophy, has been supported by several recent randomized controlled trials like that of Young et al.
There are two basic fields of thought: (I) fever should be suppressed because its metabolic costs outweigh its potential physiologic benefit in an already stressed host; vs. (II) fever is a protective adaptive response that should be allowed to run its course under most circumstances.
Experts have identified three types of delirium:Hyperactive delirium. Probably the most easily recognized type, this may include restlessness (for example, pacing), agitation, rapid mood changes or hallucinations, and refusal to cooperate with care.Hypoactive delirium. ... Mixed delirium.

Delirium can be triggered by a serious medical illness such as an infection, certain medications, and other causes, such as drug withdrawal or intoxication.

All types of delirium can include the following symptoms:confusion or disorientation.memory loss.slurred speech or difficulty speaking coherently.difficulty concentrating.hallucinations.changes in sleep patterns.changes in mood or personality.
Physical and neurological exams. The doctor performs a physical exam, checking for signs of health problems or underlying disease. A neurological exam — checking vision, balance, coordination and reflexes — can help determine if a stroke or another neurological disease is causing the delirium.
A DNR is a request not to have CPR if your heart stops or if you stop breathing. You can use an advance directive form or tell your doctor that you don't want to be resuscitated. Your doctor will put the DNR order in your medical chart. Doctors and hospitals in all states accept DNR orders.
It is also used to support breathing during surgery. Ventilators, also known as life-support machines, won't cure an illness, but they can keep patients alive while they fight an infection or their body heals from an injury.
Hospice service is often recommended when: Curative treatments are no longer effective or a cure for the disease is not available. Potential treatments are offered with the goal of extending life, but the patient may see the side effects of treatment as worse than the condition itself. The patient has uncontrolled pain ...
Late afternoon and early evening can be difficult for some people with Alzheimer's disease. They may experience sundowning—restlessness, agitation, irritability, or confusion that can begin or worsen as daylight begins to fade—often just when tired caregivers need a break.
