The Anxious Patient and the Missed Medical History
A 34-year-old woman attends for a routine scale and polish. She mentions she is 'a bit nervous' and that she fainted at her last dental appointment. As you seat her, she reports feeling light-headed and clammy. You notice she is pale and her breathing is shallow. Her medical history form, completed six months ago, lists no conditions and no medications. While preparing the surgery you also notice the autoclave log shows the last cycle as 'failed' but the instruments in the drawer are marked as sterilised. The dentist is running 20 minutes behind and asks you to 'get her ready and start the suction'.
1. What is your immediate priority in the first 60 seconds, and how does your medical-history finding change your approach?

Immediate priority: patient safety over throughput.
- Recognise the vasovagal picture: pale, clammy, light-headed, shallow breathing after a previous faint. Do not seat her upright and lean her back abruptly.
- Lay her flat (or head-down, legs raised) to restore cerebral perfusion, loosen tight clothing, and stay with her. Do not leave her alone.
- Do not start treatment or apply suction to an unwell, unassessed patient. The dentist's request to 'start the suction' must wait until the patient is stable and assessed.
Why the history matters: a blank form completed six months ago is not evidence of no disease. Fainting may relate to anxiety, but could also reflect hypoglycaemia, arrhythmia, or medication effects. You should re-take a focused history once she is stable, including medications, previous faints, and whether she has eaten.
The judgement tested: you escalate and stabilise rather than comply with an instruction that would compromise the patient.
2. The failed autoclave cycle is discovered. What should you do, and what does this reveal about your professional accountability?

Action:
- Quarantine the instruments marked as sterilised from the failed cycle. Do not use them.
- Report the failed cycle to the person responsible for decontamination and record it in the log.
- Use only instruments with a validated, passed cycle for this patient.
Accountability:
- You are accountable for the safety of the environment you prepare, even when the dentist is behind schedule. Time pressure is not a justification for using unvalidated instruments.
- A failed cycle with instruments still labelled 'sterilised' is a systems failure; documenting and escalating it protects every subsequent patient, not just this one.
- Raising it may feel like it delays the list, but the professional standard is to speak up and record, not to stay silent to avoid conflict.
