Mismanaging syncope (positioning/oxygen/glucose check ignored)
What it is
When a patient (or accompanying parent) develops vasovagal syncope (fainting), the clinician delays or skips the basic first-line measures, especially: • Not placing the patient flat (supine) and elevating the legs • Not following ABC assessment (airway/breathing/circulation) and not giving oxygen when clinically indicated • Not considering hypoglycaemia when relevant (and not giving oral glucose after recovery when appropriate) • Allowing rapid sitting/standing → repeat syncope / falls Syncope is widely described as the most common medical emergency encountered in dental practice.
Why it happens
• Mislabeling presyncope as "just anxiety" and not acting at early signs (pallor, sweating, nausea, dizziness) • Keeping the patient upright (chair position), worsening cerebral hypoperfusion • No team routine (no assigned roles for positioning, vitals, glucose check, documentation) • Confusion about positioning: guidance supports lying flat with leg elevation rather than extreme head-down positioning
