Martin et al described a risk stratification system that predicted an increased incidence of death at 1 year on the basis of abnormal ECG findings, a history of ventricular arrhythmia, a history of CHF, and age older than 45 years. Reassess after intervention. Ann Emerg Med. In patients brought to the emergency department with a presumptive diagnosis of syncope, appropriate initial interventions may include the following: The treatment choice for syncope depends on the cause or precipitant of the syncope, as follows: See Treatment and Medication for more detail. Cerebral perfusion is maintained relatively constant by an intricate and complex feedback system involving cardiac output (CO), systemic vascular resistance (SVR), mean arterial pressure (MAP), intravascular volume status, cerebrovascular resistance with intrinsic autoregulation, and metabolic regulation. Ann Emerg Med. Syncope in a patient with poor baseline cardiac function portends a poor prognosis, irrespective of etiology. Morbidity from syncope includes recurrent syncope, which occurs in 20% of patients within 1 year of the initial episode. Other conditions can mimic syncope. Potential complications of being unconscious for a long period of time include coma and brain damage. [Medline]. One small retrospective study by Pratt and Fleisher reported a prevalence of less than 0.1% in children. The San Francisco Syncope Rule (SFSR) was determined to have a 96% sensitivity for identifying patients at immediate risk for serious outcomes within 7 days, on the basis of  the presence of abnormal ECG findings, a history of CHF, dyspnea, a hematocrit level lower than 0.30, and hypotension. [Medline]. A risk score to predict arrhythmias in patients with unexplained syncope. 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. Nursing 1st year 2. (If the patient is stable, I will usually start with a much lower dose (0.04mg IV) to avoid precipitating rapid opioid withdrawal.) Clinical policy: critical issues in the evaluation and management of adult patients presenting to the emergency department with syncope. Although most causes of syncope are benign, this symptom presages a life-threatening event in a small subset of patients. 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.

[17], Sarasin et al demonstrated a risk of arrhythmia that is proportional to the number of cardiac risk factors, including abnormal ECG findings, history of CHF, and age older than 65 years. Because people in a coma can't express themselves, doctors must rely on physical clues and information provided by families and friends. Clinical judgment, Osservatorio Epidemiologico sulla Sincope nel Lazio (OESIL) score, Complications of Unconsciousness including hidden complications, secondary medical conditions, symptoms, or other types of Unconsciousness complication. In non-trauma patients, however, there are no such firm recommendations regarding airway management and the GCS score may be less useful. [2] The following considerations are relevant: Other diagnostic tests and procedures include the following: Prehospital management of syncope may require the following: Advanced triage decisions, such as direct transport to multispecialty tertiary care centers, may be required in select cases. Seizure. Lacerations, extremity fractures, head injuries, and motor vehicle accidents can occur secondary to syncope. [Medline]. [1] with an inability to maintain postural tone that is followed by spontaneous recovery. It is unclear whether hospital inpatient admission of asymptomatic patients after syncope affects outcomes. Background Tracheal intubation is recommended in unconscious trauma patients to protect the airway from pulmonary aspiration of gastric contents and also to ensure ventilation and oxygenation. Emerg Med J. Syncope Evaluation in the Emergency Department Study (SEEDS): a multidisciplinary approach to syncope management. 1984 Apr 1. [25] and SFSR criteria all have relatively low sensitivities individually for predicting severe short-term outcomes.

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. Consciousness is not a lights-on/lights-off proposition, which the term unconscious implies. Signs of impending herniation: Intubate; provide analgesia and sedation; elevated the head of the bed; respirate to a target pCO 2 of 35mmHg; Mannitol 0.5-1gram IV or 3% hypertonic saline 2-3ml/kg IV bolus.

David A Peak, MD Associate Residency Director of Harvard Affiliated Emergency Medicine Residency; Attending Physician, Massachusetts General Hospital; Assistant Professor, Harvard Medical School Drugs such as alcohol cause orthostatic intolerance, and medications such as vasodilators and antidepressants block orthostatic reflexes. 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. Preliminary data suggests that although syncope may recur in this subset of patients, the frequency is reduced by more than 50%. Syncope can also result from an acute myocardial infarction (MI), acute aortic dissection, and pulmonary embolus. Sheldon R, Connolly S, Rose S, et al. Guse SE, Neuman MI, O'Brien M, et al.

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. SVR can drop secondary to vasomotor instability, autonomic failure, or vasodepressor/vasovagal response. 2016 Sep. 18 (9):1427-33. 5(2):80-2. Middlekauff et al studied 491 patients with NYHA functional class III or IV disease and noted that, regardless of the cause, 45% of those with syncope died within 1 year, whereas 12% of those without syncope died during the same interval.

Am J Cardiol. Bradyarrhythmias include sick sinus syndrome, sinus bradycardia, high-grade atrioventricular blocks, pacemaker malfunction, and adverse medication reactions. Orthostatic hypotension increases in prevalence with age as a blunted baroreceptor response results in failure of compensatory cardioacceleration. These patients tend to have fewer recurrences and have a more sudden onset with few, if any, presyncopal symptoms. [7] but can occur at any age. Studies evaluating mortality within 4 weeks of presentation and 1 year after presentation both report statistically significant increases in this patient group. [Medline].

At times, however, the diagnosis is uncertain even after the examination is completed, and it is necessary to defer even the preliminary categorization of patients until the imaging or metabolic tests are carried out and the most serious infections or metabolic abnormalities have been considered. 98(4):365-73. Research-based and consensus guideline recommendations are as follows: Imaging studies that may be helpful include the following: A standard 12-lead ECG is a level A recommendation in the 2007 ACEP consensus guidelines for syncope. These may be associated with palpitations, chest pain, or dyspnea. Various studies suggest categorizing patients older than 45 years, 65 years, and 80 years as being at higher risk.

Am J Med. Inpatient admission should be reserved for patients in whom identification of specific immediate risk is needed (eg, those with structural heart disease or a history of ventricular arrhythmia). Volume depletion due to blood loss, vomiting, diarrhea, poor oral intake, and diuretics also causes orthostatic syncope. [Medline]. Management of-unconscious-patient 1.
