Acupuncture: Point Selection, Needling Method and Safety
What to master
Three layers must be secure: point location and functions (channel, regional anatomy, key indications), treatment strategy (local, adjacent, distal, and symptom-specific points; front–back, left–right, and channel-pairing approaches), and needling technique and safety (depth, angle, Deqi, retention, moxibustion and cupping adjuncts).
Traps to expect
- Anatomy near danger zones - pneumothorax risk at upper thoracic and supraclavicular points; vascular and nerve structures at the neck, axilla, and popliteal fossa. Questions ask for angle and depth, not just location.
- Absolute versus relative contraindications - needling through infected or broken skin, over lymphoedematous limbs after cancer surgery, in severe coagulopathy, or on a patient who has not eaten; distinguish these from conditions needing merely modified technique.
- Point function confusion - points sharing a region but differing in action (e.g. one clears heat, its neighbour moves qi).
- Deqi - described as a subjective ache, distension, or heaviness; its absence is not automatically an error, but sharp radiating pain suggests nerve contact and requires withdrawal.
- Adverse events - fainting (needle shock), haematoma, retained or bent needle, burns from moxa. Know immediate management: stop, lie flat, elevate legs, keep warm, monitor.
Worked example
A patient reports dizziness and pallor minutes after needling; the needle is still in place. Rule of thumb: stop needling, withdraw needles, position supine with legs elevated, ensure airway and warmth, monitor pulse and consciousness, and escalate if no rapid recovery. Document the event, the points, and the patient's state beforehand - including whether they had eaten. Most needle-shock questions are answered by this sequence plus prevention advice (treat relaxed, fed patients; use fewer points initially; stay with first-time patients).
