Complications of Unconsciousness including hidden complications, secondary medical conditions, symptoms, or other types of Unconsciousness complication. Cardiac (cardiopulmonary) syncope may be due to vascular disease, cardiomyopathy, arrhythmia, or valvular dysfunction and predicts a worse short-term and long-term prognosis.  and SFSR criteria all have relatively low sensitivities individually for predicting severe short-term outcomes. Fortunately, with constant attention to the changing state of consciousness and a willingness to reconsider the situation minute by minute, few mistakes should be made. Management of-unconscious-patient 1. At all times during the diagnostic evaluation and treatment of a patient who is stuporous or comatose, the physician must ask him-or herself whether the diagnosis could possibly be wrong and whether he or she needs to seek consultation or undertake other diagnostic or therapeutic measures.

In the United States alone, an estimated $2 billion annually is spent on patients hospitalized with syncope. Syncope due to orthostatic hypotension can occur through several mechanisms. In non-trauma patients, however, there are no such firm recommendations regarding airway management and the … Management of the unconscious trauma patient may be limited in the prehospital setting, as surgical intervention may be necessary. Birnbaum A, Esses D, Bijur P, Wollowitz A, Gallagher EJ. Was loss of consciousness with rapid onset and short duration? Patients with New York Heart Association (NYHA) functional class III or IV who have any type of syncope have a mortality as high as 25% within 1 year. Risk factors associated with severe short-term outcomes included abnormal ECG, history of CHF, age older than 65 years, male gender, history of chronic obstructive pulmonary disease (COPD), structural heart disease, presence of trauma, and lack of prodromal symptoms.

Syncope is a prevalent disorder, accounting for 1-3% of emergency department (ED) visits and as many as 6% of hospital admissions each year in the United States. Although unconscious patients most commonly present to the Emergency Department, the competencies to care for these patients are required by acute and general physicians. This type of syncope is generally unrelated to posture and can occur during lying, sitting, or standing. Usability of the head upright tilt test for differentiating between syncopal and seizure-like events in children. Patients may be trained to avoid situations that prompt syncope in situational cases.

Ann Emerg Med. Prolonged loss of consciousness (coma, defined as a Glasgow Coma Score of 8 or less) is seen commonly: (1) following head injury, (2) after an overdose of sedating drugs, and (3) in the situation of ‘nontraumatic coma’, where there are many possible diagnoses, but the most common are postanoxic, postischaemic, systemic infection, and metabolic derangement, e.g. Failure to validate the San Francisco Syncope Rule in an independent emergency department population.

These causes tend to be more benign and do not predict poor outcomes. 2014 Feb 17. Studies evaluating mortality within 4 weeks of presentation and 1 year after presentation both report statistically significant increases in this patient group. The syncope is thought to occur secondary to efferent vasodepressor reflexes by a number of mechanisms, resulting in decreased peripheral vascular resistance. 1985 Jul-Aug. 16(4):626-9.

SVR can drop secondary to vasomotor instability, autonomic failure, or vasodepressor/vasovagal response. Am J Cardiol. Generally, these patients have a history of cardiac problems and are symptomatic. The rule performed with a sensitivity of 90% (44/49 outcomes; 95% confidence interval [CI] 79-96%) and a specificity of 33%, which was much lower than previously reported. In the United States, the leading cause of death in young adults is trauma. Low flow states, such as those associated with advanced cardiomyopathy, congestive heart failure (CHF) , and valvular insufficiency, may result in hypotension and cause transient global cerebral hypoperfusion. Brain tissue cannot store energy in the form of the high-energy phosphates found elsewhere in the body; consequently, a cessation of cerebral perfusion lasting only 3-5 seconds can result in syncope. Classically, nausea, diaphoresis, fading or "graying out" of vision, epigastric discomfort, and light-headedness precede syncope by a few minutes. Syncope-related injury during driving is rare, but it has been documented. 110(24):3636-45. History and physical examination are the most specific and sensitive ways of evaluating syncope.
