Syncopal episode vasovagal10/2/2023 ![]() ![]() This usually causes a slowing of the heart beat, and dilatation and pooling of the blood vessels in the leg, which lowers the blood pressure. Syncope usually occurs when the nervous system that controls the heart rate and blood pressure (the autonomic nervous system) starts to malfunction transiently in response to a trigger. ![]() This condition is very common, with 1 in 3 individuals experiencing syncope at some stage in their life. McGraw-Hill Education.Vasovagal syncope (pronounced sin-cope-pee) is a term used to describe an episode of fainting due to a low blood pressure, or heart rate, or a combination of both these factors. CURRENT Medical Diagnosis & Treatment (15th ed.). MEDICAL-SURGICAL NURSING: Patient-Centered Collaborative Care (8th ed.). Ignatavicius, D., Workman, M., Blair, M., Rebar, C., & Winkelman, C. In conclusion, vasovagal syncope common faint which usually does not involve any dangerous underlying health problem.īy leg crossing combined with tensing muscles of both extremities can postpone or prevent the vasovagal attack. Avice to wear compression stockings or abdominal binders.Advice to talk to consulting doctor regarding discontinuing the medicine like diuretic which could lower blood pressure.Sit down and put the head between both knees until the patient feels better.Lie down and elevating foot above heart level to increase blood flow to the brain by gravity.For instance, crossing legs along with squeezing the muscles of hands and foot to increase peripheral vascular resistance to.Teach the patient maneuvers to prevent the vasovagal attack.For example, standing for a long time or the sight of blood. Ask the patient to identify and avoid triggers that cause a vasovagal reaction.Reassure the patient after the vasovagal attack.Be aware of the most common triggers for a vasovagal reaction such as,.Closely observe for any signs and symptoms of vasovagal attack during procedures.Ensure adequate hydration before the procedure.If the patient is likely to have a vasovagal attack, briefly explain the maneuver to prevent a syncopal episode by intensely contracting hands, hands, arms, feet, and legs while releasing the muscles of the belly, bottom, and chest.Take a thorough patient medical and surgical history. ![]() Inserting an electrical pacemaker to regulate the heartbeat.Serotonin reuptake inhibitors (SSRIs), to moderate the nervous system response.Corticosteroids, to help increase the sodium and fluid levels.Alpha-1-adrenergic agonists, to increase blood pressure.For instance, the frequency of recurring vasovagal attacks interferes with the quality of life of the patient. The majority of the patients experiencing vasovagal syncope don’t need any treatment because episodes are self-limiting in nature.īut in rare cases, medical or surgical intervention may be needed. Like any other health condition, diagnosing a vasovagal syncope begins with in-depth past medical history along with a thorough physical examination. A sudden sensation of feeling hot or cold.Visual disturbances such as blurred vision, tunnel vision.Causes of vasovagal syncopeįollowing are the sign and symptoms of the vasovagal attack. This sudden hemodynamic imbalance results in transient loss of consciousness – syncope. The combination of bradycardia and hypotension reduces the normal blood flow to the brain significantly. Ultimately, causing a sudden drop in blood returning to the heart. As a result, peripheral vascular resistance decreases. This leads to peripheral vasodilatation and the pooling of blood in the extremities. Pathophysiology of vasovagal syncope is initiated by stressful, painful, or claustrophobic intense emotions, causing hyper-stimulated vagus nerve. Vasovagal Syncope is characterized by transient loss of consciousness due to hypotension, peripheral vasodilation, and bradycardia as a result of over-stimulation of the vagus nerve. The frequency of vasovagal attacks may vary from once a year to a weekly or even daily basis. Also, the sense of lack of physical control could lead to low self-esteem. Although, fainting poses a risk of trauma. Generally, there is no serious underlying cause of vasovagal reflex syncope. For instance, the sight of blood, stress, severe pain, or intense emotions and phobias. It happens as a result of certain triggers. Vasovagal Syncope is the most common type of syncope – faint.
