Reflex (neurally mediated) syncope may be due to vasovagal syncope, which is mediated by emotional distress such as fear or physical pain. [15], Risk of serious outcome and death in patients with syncope increases with higher peak troponin concentrations, according to a prospective cohort study of 338 patients who had plasma troponin I levels measured with a sensitive assay 12 hours after syncope. Syncope is defined as a transient, self-limited loss of consciousness Nursing Standard, 20,1, 54-64.

Outpatient management can be used for patients who are at low risk for a cardiac etiology to define a precise cause so that mechanism-specific treatment can be effected. 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.

The authors concluded that further study was needed. Patients with cardiac syncope may be significantly restricted in their daily activities, and the occurrence of syncope may be a symptom of their underlying disease progression. Emerg Med J. The ventilatory rate should not exceed 10-12 breaths per minute. The unconscious patient is completely dependent on the nurse to manage all their activities of daily living and to monitor their vital functions. Syncope in children and adolescents. Situational syncope is essentially a reproducible vasovagal syncope with a known precipitant.

Clin Auton Res. Atkins D, Hanusa B, Sefcik T, Kapoor W. Syncope and orthostatic hypotension. Evaluation by a cardiologist for pacemaker placement should be considered in select patients older than 40 years who have recurrent syncope that is confirmed to be neurally mediated syncope (NMS) with a documented period of asystole. In order to achieve the best possible outcomes while decreasing the risk of undetected injuries, the management of trauma patients requires a highly systematic approach. Supraventricular tachyarrhythmias include supraventricular tachycardia and atrial fibrillation with rapid response. The approach is based on the belief that after a history and a general physical and neurologic examination, the informed physician can, with reasonable confidence, place the patient into one of four major groups of illnesses that cause coma. Vasovagal syncope is the most common type in young adults 2005 Nov. 150(5):1065. Most published methods of risk stratification take into account cardiac symptoms and risk factors.
