Low-BMI Patient with COPD Requests Deep Needling at Thoracic Points
A 68-year-old man, 170 cm tall and 52 kg (BMI 18.0), seeks care for upper trapezius and interscapular pain that worsens with coughing. He has a 40-pack-year smoking history and mild COPD; today he has a productive cough but no fever, and SpO2 is 96% on room air. Pain is 6/10. He points to GB21, BL13, SI11, and LU1 as the areas that helped after a previous course of acupuncture. He asks for deep needling like before because a prior practitioner used long needles. The clinic has 0.25 x 40 mm and 0.30 x 75 mm needles. He becomes restless and coughs during point palpation. He has no history of pneumothorax, but his ribs are visible and his intercostal spaces are thin.
1. Select safe needling parameters for the named points and justify them.

The risk is iatrogenic pneumothorax. GB21 lies over the apex of the lung, BL13 is at the T3 level paraspinally, and LU1 is over the first intercostal space; all three require shallow, angled needling, especially in a thin patient with COPD. I would use 0.25 x 25 mm or 0.25 x 30 mm needles and avoid the 75 mm needles entirely. At GB21 I would needle obliquely or nearly transversely to 0.5-0.8 cun, not perpendicularly toward the lung. At BL13 I would needle obliquely toward the spine at 0.5-0.8 cun. At LU1 I would use a transverse or oblique direction at 0.5-0.8 cun. SI11 is in the infraspinous fossa and is less risky, but I would still use a standard depth of about 1-1.5 cun and avoid angling medially toward the chest wall. Because he coughs during palpation, I would treat him seated or side-lying, stop if he coughs while a needle is in place, and avoid retaining needles at thoracic points during a coughing paroxysm.
2. What signs would make you suspect a pneumothorax, and what would you do?
Read the worked answer
I would suspect pneumothorax if he develops sudden pleuritic chest pain, shortness of breath, a dry cough, tachycardia, anxiety, diminished breath sounds on one side, or subcutaneous emphysema after needling. Symptoms may be delayed, so I would give explicit return precautions. If any sign appears, I would stop treatment, remove all needles, assess airway, breathing, and circulation, place him upright as tolerated, give oxygen if available, and call emergency services. I would not attempt to need another point or to treat through the symptoms. I would monitor pulse, blood pressure, respiratory rate, and SpO2 while waiting and document the time of onset and the points used. The reasoning is that pneumothorax can progress rapidly and is a medical emergency; the acupuncture clinic's role is recognition and transfer, not definitive management.
3. How would you document informed consent and the rationale for not using deep needling?
Read the worked answer
I would record that the patient requested deep needling based on prior experience, that his low BMI and COPD increase thoracic risk, and that I explained the risk of pneumothorax. I would document that I offered a modified shallow technique and that he agreed. I would list the exact points, needle dimensions, angles, depths, and retention time, and note that long needles were not used. I would also note his coughing during treatment and any positioning changes. The purpose is not defensive paperwork but a clear record that the technique was chosen deliberately for his anatomy and that he understood the reason for the change. If he insisted on deep needling, I would document the refusal and offer a referral rather than proceed.
