PROCEDURES

For patients with altered mental status or meningismus,

a lumbar puncture should be performed to evaluate the

cerebrospinal fluid for infectious causes (see Chapter 5).

MEDICAL DECISION MAKING

The differential diagnosis for fever is extensive, and the cause

can be infectious or noninfectious. The majority of causes of

fever are infectious (Table 33-2). Noninfectious causes

include pulmonary embolism, intracranial hemorrhage,

cerebrovascular accident, neuroleptic malignant syndrome/

serotonin syndrome, malignant hyperthermia, thyroid
