Study Notes
Definitions and Overview
- Syncope refers to a sudden, transient loss of consciousness and postural tone with spontaneous recovery, indicating a brief period of unconsciousness.
- Often caused by cerebral ischemia due to loss of cerebral oxygenation and blood perfusion.
- Can signal underlying medical conditions, frequently triggered by stress, particularly during dental visits.
Predisposing Factors
- Psychogenic Factors: Fright, anxiety, stress, pain, and sight of blood or dental instruments contribute to syncope risks.
- Non-Psychogenic Factors: Exhaustion, hunger, poor physical condition, hot environments, male gender, pregnant women, and ages between 16-35 are notable risks.
- Male societal expectations may deter emotional expression, increasing the risk of fainting.
- Pregnant women experience orthostatic hypotension and reduced lung capacity, heightening syncopal risks.
Types of Syncope
-
Neurocardiac Syncope:
- Most common type; often triggered by unexpected pain, fear, or exhaustion.
- Manifests from a sudden drop in blood pressure and heart rate; stress response leads to inadequate blood flow to the brain.
-
Cardiac Syncope:
- Second most common; linked to inadequate cardiac output due to arrhythmias or heart obstructions, potentially fatal.
- Requires immediate medical referral.
-
Non-Cardiac Syncope:
- Can result from seizures, hyperventilation, metabolic disorders (e.g., hypoglycemia), and orthostatic hypotension.
- Situational occurrences, such as strenuous efforts (e.g., Valsalva maneuver), can trigger episodes.
Signs and Symptoms of Pre-Syncope
- Early indications include pallor, pupil dilation, cold sweats, goosebumps, dizziness, nausea, heart palpitations, chest pain, and shortness of breath.
- Symptoms may progressively worsen, leading to syncope characterized by reduced heart rate and weak pulse.
Emergency Preparedness and Patient Care
- Immediate action during a syncopal episode includes:
- Removing all instruments from the mouth and positioning the patient supine with elevated feet.
- Ensuring circulation, airway, and breathing (C-A-B) are stable.
- Administering oxygen, monitoring vital signs, and loosening tight clothing.
Additional Treatment Considerations
- An ammonia inhalant may be used cautiously for non-injured patients; however, caution is advised for those with respiratory or eye issues.
- If unconsciousness persists over one minute, emergency medical services (EMS) must be summoned.
- After regaining consciousness, patients should remain supine until fully recovered before resuming normal positioning.
Post-Episode Guidance
- Treatment should be suspended for the day, and an emergency contact should escort the patient home due to high reoccurrence within the first 24 hours.
- Document syncopal episodes thoroughly in the patient's chart for future reference and care continuity.
